About Hobart

Hobart is the state capital and most populous city of the Australian island state of Tasmania. Founded in 1803 as a penal colony, Hobart is Australia's second oldest capital city after Sydney. In 2009, the city had a greater area population of approximately 212,019. A resident of Hobart is known as a "Hobartian". The city is located in the state's south-east on the estuary of the Derwent River. The skyline is dominated by Mount Wellington at 1,271 metres high.

 

The city is the financial and administrative heart of Tasmania, and also serves as the home port for both Australian and French Antarctic operations.

 

Hobart was named Australia's 6th most sustainable city, by the Australian Conservation Foundation in 2010. For economic and social innovation, Hobart was the 11th placed in Australia in 2009, and listed as an innovation influencer city in the Innovation Cities Global Index scoring equal with Reykjavik, Katowice and Casablanca by 2thinknow.

 

About the Tasman Bridge

The Tasman Bridge is a five-lane bridge crossing the Derwent River, near the CBD of Hobart, Tasmania. The bridge has a total length (including approaches) of 1,395 metres (4,576 ft). It provides the main traffic route from the CBD (on the western shore) to the eastern shore - particularly Hobart International Airport and Bellerive Oval. It has a pedestrian foot way on each side, but no dedicated lane for bicycles. However, steps to the pedestrian foot way have recently been replaced with on-ramps.

 

On Sunday 5 January 1975, at 9:27 p.m. Australian Eastern Summer Time, the Tasman Bridge was struck by the bulk ore carrier Lake Illawarra, bound for the Electrolytic Zinc Company with a cargo of 10,000 tons of zinc concentrate. It caused two pylons and three sections of concrete decking, totaling 127 metres (417 ft), to fall from the bridge and sink the ship. Seven of the ship's crewmen were killed, and five motorists died when four cars drove over the collapsed sections before the traffic was stopped.

Undergoing repair (HT capacitor replacement)

 

The bias electrolytics have already been replaced on the rectifier board. The removed units checked out fine on my capacitor tester.

 

The root cause of my problem (low and ripply HT) was that one of the two main HT smoothing capacitors had completely failed open circuit. My capacitor tester didn't even register there was a capacitor present when I tested the faulty component!

 

All of the other high voltage capacitors actually checked out OK, though they all tended to be somewhat high in value, which is often regarded as a sign that they are on their way out.

 

The main replacement HT capacitors are of the newer "snap-in" design which required some work to fabricate mounting points for the existing wiring to connect to. This was achieved using stout tinned copper wire, and appears so far to have been a success.

JJ read there was a stall at the kite festival that sold Himalayan salt, and having read somewhere that it was a cure for migraines, I was keen to get down there to see if I could get some. Luckily there were a few jars on the stall, so I bought one for £3. The guy recommended sprinkling in the bath from time to time, but I am keen to try and follow this info that I found on the internet:

 

People that suffer from Migraine are often anxious to get rid of the terrible and annoying pain characterizing this condition. There is a common thinking that a migraine is not a big deal, but a really bad migraine can pretty much handicap and take you down for the rest of the day.

 

In worst cases, there are some migraines that can’t be defeated with your usual pain killers. So, here is the best thing to use for migraine relief – Himalayan Salt!

 

This salt will reduce the severity of your migraine headaches. It will strengthen your immune system, increase your energy levels, and balance the serotonin levels in your bloodstream. Also it will restore the body’s electrolyte and alkaline balance and much more.

 

In a glass mix a high concentration of Himalayan crystal salt (2 teaspoons) with cup of lemon juice, together with the lemon zest (use organic lemons) and cup of water. You will feel instant migraine relief.

THE RUNCORN BRIDGE CHESHIRE

 

The Silver Jubilee Bridge crosses the River Mersey and the Manchester Ship Canal at Runcorn Gap between Runcorn and Widnes in Cheshire, England. It is a through arch bridge which was opened in 1961 and widened in 1975–77. It carries the A533 road and a cantilevered footway. The bridge is a grade II listed building.

 

History

 

Until 1868, when Runcorn Railway Bridge was opened, the only means of crossing the Mersey at or near Runcorn Gap were by fording or by ferry.Before that the lowest crossing of the river had been the road bridge at Warrington.The first bridge to carry vehicular traffic across Runcorn Gap was the Widnes-Runcorn Transporter Bridge which opened in 1905.This was an inefficient means of transport and it had become inadequate for the amount of traffic using it before the outbreak of the Second World War. In 1946 the Ministry of Transport agreed that the transporter bridge should be replaced when sufficient funds were available. Mott, Hay and Anderson were appointed as consultant engineers.

  

Planning

 

The new bridge had to allow the passage of shipping along the Manchester Ship Canal. Many ideas were considered, including a new transporter bridge or a swing bridge. These were considered to be impractical and it was decided that the best solution was a high-level bridge upstream from the railway bridge. This would allow the least obstruction to shipping and would also be at the narrowest crossing point. The first plan for a high-level bridge was a truss bridge with three or five spans, giving a 24 feet (7 m) dual carriageway with a cycle track and footpaths. This was abandoned because it was too expensive, and because one of the piers would be too close to the wall of the ship canal. The next idea was for a suspension bridge with a span of 1,030 feet (314 m) between the main towers with a 24 feet (7 m) single carriageway and a 6 feet (2 m) footpath. However aerodynamic tests on models of the bridge showed that, while the bridge itself would be stable, the presence of the adjacent railway bridge would cause severe oscillation. The finally accepted design was for a steel arch bridge with a 30 feet (9 m) single carriageway.The design of the bridge is similar to that of Sydney Harbour Bridge but differs from it in that the side spans are continuous with the main span rather than being separate from them. This design feature was necessary to avoid the problem of oscillation due to the railway bridge. The main span measures 1,082 feet (330 m) and each side span is 250 feet (76 m).

   

Construction

 

This began on 25 April 1956. The contractors for the first phase of work, Leonard Fairclough of Adlington, cleared the ground and constructed the foundations for the piers. The contract for the second phase, the building of the main arch and the side arches, was given to Dorman Long who sub-contracted the building of the bridge deck, viaduct and roadworks to Leonard Fairclough. Building of the bridge itself began in March 1958 and the side spans were completed by November 1959. The main arch was built by cantilevering steelwork from the side spans until it met in the middle in November 1960. The carriageway was suspended from the arch by 48 lock-coil wire ropes.From February 1960 approach roads and viaducts were being built on both sides of the river; the total length of viaduct constructed was 1,574 feet (480 m).The approaches on the Runcorn side blocked the Bridgewater Canal at Waterloo Bridge and the line of locks leading down to the Mersey were filled in.The bridge was officially opened on 21 July 1961 by Princess Alexandra.

   

Statistics

 

The main arch is 1,082 feet (330 m) long and each side arch measures 250 feet (76 m). During its construction 720,000 rivets were used. Its height over the river bed is 285 feet (87 m) and the headroom over the ship canal is 80 feet (24 m). During its construction 5,900 tons of steel were used and 7,500 tons of concrete. The bridge requires constant repainting and for this one coat uses 6,000 imperial gallons (27,277 l) of paint. On the Runcorn side, the approach viaducts are 1,076 feet (328 m) in length, and on the Widnes side 498 feet (152 m). The cost of constructing the bridge was £2,433,000.At the time of its construction it had the third longest steel arch span in the world. It had the longest vehicular span in the country, but this record was held for only a few weeks until the Tamar Bridge was completed. By 2001 it was the 10th longest steel arch bridge, and at that time was just 20 centimetres (8 in) short of having Europe's largest span.

   

Consequences

 

The bridge transformed Runcorn from an effective cul-de-sac into a town with through traffic. Road communications between north Cheshire and south Lancashire were immediately improved. Trade at the Port of Runcorn increased sixfold between 1960 and 1970. The bridge provides a connection between the M56 and the M62. Its presence enabled the development of the New Town in Runcorn in the late 1960s and the 1970s. The amount of traffic using the bridge trebled between 1961 and 1970.This led to such severe congestion that in 1975 the bridge was widened and the approach roads were improved. The carriageway was widened to incorporate the footpaths, giving it four lanes, and a cantilevered footway was built on the east side of the bridge. This was completed in 1977 and in that year the bridge was re-named from Runcorn Bridge to the Silver Jubilee Bridge to commemorate the Queen's silver jubilee.Since 1994 the bridge has been illuminated at night by floodlights. Repairs to chloride corrosion of the bridge's deck were carried out in the early 21st century using an innovative electrolytic method; they were shortlisted for the Prime Minister's Award for Better Public Building of 2010.

 

Traffic on the bridge has continued to grow to over 80,000 vehicles a day, and there is frequent congestion.In order to alleviate this the building of further crossing is planned, known as the Mersey Gateway. This is planned to be a six-lane toll bridge to the east of the Silver Jubilee Bridge.

Triumph Stag (1970-77) Engine 2997cc V8 OC Total Production 25,877 (of which 6780 were exported to the USA)

Registration Number GVD 370 N (Luton)

TRIUMPH SET

www.flickr.com/photos/45676495@N05/sets/72157623847263736...

Built as a 2 door 2+2, convertible or hardtop. Originally conceived as a short chassis open top version of the Triumph 2000, but ended with a monocoque and a V8 engine of 145bhp not shared with any other Triumph. Overdrive at first optional, becoming standard in 1972, and many with Automatics.

The car initially received an enthusiastic welcome, but suffered from engine reliability problems, attributed to several design faults, firstly a coolant problem caused by the water pump being set above the engine, if coolant was lost via via the expansion bottle, the coolant level droppedbelow the level of the pump resulting in loss of fluid to the pump and water pump failure. Water pump failures also occurred due to poorly hardened drive gears, which wore out prematurely and stopped the water pump. Secondly the choice of materials, the engine block was constructed of iron and the heads of aluminium a combination that required the use of corrosion inhibiting anti freeze all year round a point often not realised by owners or the dealer network, resulting in cases of electrolytic corrosion, so that corroded alloy debris came loose and was distributed around inside the engine. A third cause of trouble was the engine's use of long, simplex roller link chains, which would first stretch and then often fail inside fewer than 25,000 miles , even before failure a stretched timing chain could skip links causing valve and piston damage. Another problem with the cylinder heads was the arrangement of cylinder head fixing studs, half of which were vertical and the other half at an angle. The angled studs when heated and cooled, expanded and contracted at a different rate to the alloy heads, causing sideways forces which caused premature failure of the cylinder head gaskets. Subsequently these design and maintainance faults have been recognise and addressed by owners and a well maintained Stag is a very desirable classic.

During the production run modifications evolved and consequently in Stag circles different period car are referred to as "Early" Mk I 1970, the Mk I (1971–1972/3), Mk II (1973) and "Late" Mk II (1974–1977), visually the Mark 1s and Mk.2s differed only in the addition of twin coachlines to indicate Mk.II variants.

Wallerscote Island Soda Ash Works – Northwich

 

John Brunner and Ludwig Mond were industrial chemists. Their company was originally formed in 1873. They built Winnington Works in Northwich, Cheshire and produced their first soda ash a year later. They used brine solution, ammonia and limestone to produce sodium carbonate in pure form, and with fewer by-products using the solvay process. They chose Winnington because it sits on a bed of salt 600 feet thick, is fairly close to the Buxton limestone quarries and had good transport links.

 

By 1881, the partnership was well established and became a limited company, producing 200,000 tons of soda ash each year. Brunner Mond established themselves as the country’s biggest soda ash producer and continued to expand. In time, Brunner Mond & Co. provided virtually all of Britain’s soda ash, and became the world’s largest alkali exporter. Wallerscote island Works was completed in 1926. An almost bizarre like construction of silos and huge metal sheds although all were integral parts of the original structure. The company later became part of ICI which is now owned by Tata.

 

Sodium Carbonate is a widely used in industry for casting and glassmaking. It is commonly used in chemistry as a base and an electrolyte. It is also used domestically in detergents, dyes and toothpaste as well as tasty sherbet sweets!

Especially after the moon landing, the further development of mankind to Mars and other planets into the powerful offensive, the world's major powers eager to Daxian hand of God, increase investment, vigorously develop new sophisticated technology projects for space to space. Satellite, space station, the new spacecraft, the new space suits, the new radiation protection materials, intelligent materials, new manufacturing technology, communications technology, computer technology, detector technology, rover, rover technology, biomedical technology, and so one after another, is expected to greater breakthroughs and leaps. For example, rocket technology, spacecraft design, large power spacecraft, spacesuits design improvements, radiation multifunctional composite materials, life health care technology and space medicine, prevention against microgravity microgravity applicable drugs, tracking control technology, landing and return technology. Mars lander and returned safely to Earth as a top priority. Secondly, Mars, the Moon base and the use of transforming Mars, the Moon and other development will follow. Whether the former or the latter, are the modern aerospace science, space science basic research, applied basic research and applied research in the major cutting-edge technology. These major cutting-edge technology research and innovation, not only for human landing on Mars and the safe return of great significance, but for the entire space science, impact immeasurable universe sciences, earth sciences and human life. Here the most critical of the most important research projects of several sophisticated technology research and development as well as its core technology brief. Limit non-scientific techniques include non-technical limits of technology, the key lies in technology research and development of technology maturity, advanced technology, innovative, practical, reliable, practical application, business value and investment costs, and not simply like the idea mature technology achievements, difficult to put into things. This is the high-tech research and development, testing, prototype, test application testing, until the outcome of industrialization. Especially in aerospace technology, advanced, novelty, practicality, reliability, economy, maturity, commercial value and so on. For technical and research purely science fiction and the like may be irrelevant depth, but not as aerospace engineering and technology practice. Otherwise, Mars will become a dream fantasy, and even into settling crashed out of danger.

 

Regardless of the moon or Mars, many technical difficulties, especially a human landing on Mars and return safely to Earth, technical difficulties mainly in the following aspects. (Transformation of Mars and the Moon and other planets and detect other livable technology more complex and difficult, at this stage it is difficult to achieve and therefore not discussed in detail in this study). In fact, Mars will be the safe return of a full set of technology, space science, aerospace crucial scientific research development, its significance is not confined to Mars simply a return to scientific value, great commercial value, can not be measure.

1. Powered rocket, the spacecraft overall structural design not be too complex large, otherwise, the safety factor to reduce the risk of failure accidents. Fusion rocket engine main problem to be solved is the high-temperature materials and fuel ignition chamber (reaction chamber temperatures of up to tens of millions of supreme billion degrees), fissile class rocket engine whose essence is the miniaturization of nuclear reactors, and placed on the rocket. Nuclear rocket engine fuel as an energy source, with liquid hydrogen, liquid helium, liquid ammonia working fluid. Nuclear rocket engine mounted in the thrust chamber of the reactor, cooling nozzle, the working fluid delivery and control systems and other components. This engine due to nuclear radiation protection, exhaust pollution, reactor control and efficient heat exchanger design and other issues unresolved. Electrothermal rocket engine utilizing heat energy (resistance heating or electric arc heating) working medium (hydrogen, amines, hydrazine ), vaporized; nozzle expansion accelerated after discharged from the spout to generate thrust. Static rocket engine working fluid (mercury, cesium, hydrogen, etc.) from the tank enter the ionization chamber is formed thrust ionized into a plasma jet. Electric rocket engines with a high specific impulse (700-2500 sec), extremely long life (can be repeated thousands of times a starter, a total of up to thousands of hours of work). But the thrust of less than 100N. This engine is only available for spacecraft attitude control, station-keeping and the like. One nuclear - power rocket design is as follows: Firstly, the reactor heats water to make it into steam, and then the high-speed steam ejected, push the rocket. Nuclear rocket using hydrogen as working substance may be a better solution, it is one of the most commonly used liquid hydrogen rocket fuel rocket carrying liquid hydrogen virtually no technical difficulties. Heating hydrogen nuclear reactor, as long as it eventually reaches or exceeds current jet velocity hydrogen rocket engine jet speed, the same weight of the rocket will be able to work longer, it can accelerate the Rockets faster. Here there are only two problems: First, the final weight includes the weight of the rocket in nuclear reactors, so it must be as light as possible. Ultra-small nuclear reactor has been able to achieve. Furthermore, if used in outer space, we can not consider the problem of radioactive residues, simply to just one proton hydrogen nuclei are less likely to produce induced radioactivity, thus shielding layer can be made thinner, injected hydrogen gas can flow directly through the reactor core, it is not easy to solve, and that is how to get back at high speed heated gas is ejected.

  

Rocket engine with a nuclear fission reactor, based on the heating liquid hydrogen propellant, rather than igniting flammable propellant

High-speed heavy rocket is a major cutting-edge technology. After all, space flight and aircraft carriers, submarines, nuclear reactors differ greatly from the one hand, the use of traditional fuels, on the one hand can be nuclear reactor technology. From the control, for security reasons, the use of nuclear power rocket technology, safe and reliable overriding indicators. Nuclear atomic energy in line with the norms and rules of outer space. For the immature fetal abdominal hatchery technology, and resolutely reject use. This is the most significant development of nuclear-powered rocket principle.

Nuclear-powered spaceship for Use of nuclear power are three kinds:

The first method: no water or air space such media can not be used propeller must use jet approach. Reactor nuclear fission or fusion to produce a lot of heat, we will propellant (such as liquid hydrogen) injection, the rapid expansion of the propellant will be heated and then discharged from the engine speed tail thrust. This method is most readily available.

The second method: nuclear reactor will have a lot of fast-moving ions, these energetic particles moving very fast, so you can use a magnetic field to control their ejection direction. This principle ion rocket similar to the tail of the rocket ejected from the high-speed mobile ions, so that the recoil movement of a rocket. The advantage of this approach is to promote the unusually large ratio, without carrying any medium, continued strong. Ion engine, which is commonly referred to as "electric rocket", the principle is not complicated, the propellant is ionized particles,

Plasma Engine

Electromagnetic acceleration, high-speed spray. From the development trend, the US research scope covers almost all types of electric thrusters, but mainly to the development of ion engines, NASA in which to play the most active intake technology and preparedness plans. "

The third method: the use of nuclear explosions. It is a bold and crazy way, no longer is the use of a controlled nuclear reaction, but to use nuclear explosions to drive the ship, this is not an engine, and it is called a nuclear pulse rocket. This spacecraft will carry a lot of low-yield atomic bombs out one behind, and then detonated, followed by a spacecraft propulsion installation disk, absorbing the blast pushing the spacecraft forward. This was in 1955 to Orion (Project Orion) name of the project, originally planned to bring two thousand atomic bombs, Orion later fetal nuclear thermal rocket. Its principle is mounted on a small rocket reactor, the reactor utilizing thermal energy generated by the propellant is heated to a high temperature, high pressure and high temperature of the propellant from the high-speed spray nozzle, a tremendous impetus.

  

Common nuclear fission technologies, including nuclear pulse rocket engines, nuclear rockets, nuclear thermal rocket and nuclear stamping rockets to nuclear thermal rocket, for example, the size of its land-based nuclear power plant reactor structure than the much smaller, more uranium-235 purity requirements high, reaching more than 90%, at the request of the high specific impulse engine core temperature will reach about 3000K, require excellent high temperature properties of materials.

  

Research and test new IT technologies and new products and new technology and new materials, new equipment, things are difficult, design is the most important part, especially in the overall design, technical solutions, technical route, technical process, technical and economic particularly significant. The overall design is defective, technology there are loopholes in the program, will be a major technical route deviation, but also directly related to the success of research trials. so, any time, under any circumstances, a good grasp of the overall control of design, technical design, is essential. otherwise, a done deal, it is difficult save. aerospace technology research and product development is true.

  

3, high-performance nuclear rocket

Nuclear rocket nuclear fission and fusion energy can rocket rocket two categories. Nuclear fission and fusion produce heat, radiation and shock waves and other large amounts of energy, but here they are contemplated for use as a thermal energy rocket.

Uranium and other heavy elements, under certain conditions, will split their nuclei, called nuclear fission reaction. The atomic bomb is the result of nuclear fission reactions. Nuclear fission reaction to release energy, is a million times more chemical rocket propellant combustion energy. Therefore, nuclear fission energy is a high-performance rocket rockets. Since it requires much less propellant than chemical rockets can, so to its own weight is much lighter than chemical rockets energy. For the same quality of the rocket, the rocket payload of nuclear fission energy is much greater than the chemical energy of the rocket. Just nuclear fission energy rocket is still in the works. 

Use of nuclear fission energy as the energy of the rocket, called the atomic rockets. It is to make hydrogen or other inert gas working fluid through the reactor, the hydrogen after the heating temperature quickly rose to 2000 ℃, and then into the nozzle, high-speed spray to produce thrust. 

A vision plan is to use liquid hydrogen working fluid, in operation, the liquid hydrogen tank in the liquid hydrogen pump is withdrawn through the catheter and the engine cooling jacket and liquid hydrogen into hydrogen gas, hydrogen gas turbine-driven, locally expansion. Then by nuclear fission reactors, nuclear fission reactions absorb heat released, a sharp rise in temperature, and finally into the nozzle, the rapid expansion of high-speed spray. Calculations show that the amount of atomic payload rockets, rocket high chemical energy than 5-8 times.

Hydrogen and other light elements, under certain conditions, their nuclei convergent synthesis of new heavy nuclei, and release a lot of energy, called nuclear fusion reaction, also called thermonuclear reaction. 

Using energy generated by the fusion reaction for energy rocket, called fusion energy rocket or nuclear thermal rockets. But it is also not only take advantage of controlled nuclear fusion reaction to manufacture hydrogen bombs, rockets and controlled nuclear fusion reaction needs still studying it.

Of course there are various research and development of rocket technology and technical solutions to try.

It is envisaged that the rocket deuterium, an isotope of hydrogen with deuterium nuclear fusion reaction of helium nuclei, protons and neutrons, and release huge amounts of energy, just polymerized ionized helium to temperatures up to 100 million degrees the plasma, and then nozzle expansion, high-speed ejection, the exhaust speed of up to 15,000 km / sec, atomic energy is 1800 times the rocket, the rocket is the chemical energy of 3700 times.

 

Nuclear rocket engine fuel as an energy source, with liquid hydrogen, liquid helium, liquid ammonia working fluid. Nuclear rocket engine mounted in the thrust chamber of the reactor, cooling nozzle, the working fluid delivery and control systems and other components.

2. radiation. Space radiation is one of the greatest threats to the safety of the astronauts, including X-rays, γ-rays, cosmic rays and high-speed solar particles. Better than aluminum protective effect of high polymer composite materials.

3. Air. Perhaps the oxygen needed to rely on oxidation-reduction reaction of hydrogen and ilmenite production of water, followed by water electrolysis to generate oxygen. Mars oxygen necessary for survival but also from the decomposition of water, electrolytically separating water molecules of oxygen and hydrogen, this oxygen equipment has been successfully used in the International Space Station. Oxygen is released into the air to sustain life, the hydrogen system into the water system.

4. The issue of food waste recycling. At present, the International Space Station on the use of dehumidifiers, sucked moisture in the air to be purified, and then changed back to drinkable water. The astronauts' urine and sweat recycling. 5. water. The spacecraft and the space station on purification system also makes urine and other liquids can be purified utilization. 6. microgravity. In microgravity or weightlessness long-term space travel, if protective measures shall not be treated, the astronauts will be muscle atrophy, bone softening health. 7. contact. 8. Insulation, 9 energy. Any space exploration are inseparable from the energy battery is a new super hybrid energy storage device, the asymmetric lead-acid batteries and supercapacitors in the same compound within the system - and the so-called inside, no additional separate electronic control unit, this is an optimal combination. The traditional lead-acid battery PbO2 monomer is a positive electrode plate and a negative electrode plate spongy Pb composition, not a super cell. : Silicon solar cells, multi-compound thin film solar cells, multi-layer polymer-modified electrode solar cells, nano-crystalline solar cells, batteries and super class. For example, the solar aircraft .10. To protect the health and life safety and security systems. Lysophosphatidic acid LPA is a growth factor-like lipid mediators, the researchers found that this substance can on apoptosis after radiation injury and animal cells was inhibited. Stable lysophosphatidic acid analogs having the hematopoietic system and gastrointestinal tract caused by acute radiation sickness protection, knockout experiments show that lysophosphatidic acid receptors is an important foundation for the protection of radiation injury. In addition to work under high pressure, the astronauts face a number of health threats, including motion sickness, bacterial infections, blindness space, as well as psychological problems, including toxic dust. In the weightless environment of space, the astronaut's body will be like in preadolescents, as the emergence of various changes.

Plantar molt

After the environment to adapt to zero gravity, the astronaut's body will be some strange changes. Weightlessness cause fluid flow around the main flow torso and head, causing the astronauts facial swelling and inflammation, such as nasal congestion. During long-term stay in space

 

Bone and muscle loss

Most people weightlessness caused by the impact may be known bone and muscle degeneration. In addition, the calcium bones become very fragile and prone to fracture, which is why some of the astronauts after landing need on a stretcher.

Space Blindness

Space Blindness refers astronaut decreased vision.

Solar storms and radiation is one of the biggest challenges facing the long-term space flight. Since losing the protection of Earth's magnetic field, astronauts suffer far more than normal levels of radiation. The cumulative amount of radiation exposure in low earth orbit them exceeded by workers close to nuclear reactors, thereby increasing the risk of cancer.

Prolonged space flight can cause a series of psychological problems, including depression or mood swings, vulnerability, anxiety and fear, as well as other sequelae. We are familiar with the biology of the Earth, the Earth biochemistry, biophysics, after all, the Earth is very different astrophysics, celestial chemistry, biophysics and astrophysics, biochemistry and other celestial bodies. Therefore, you must be familiar with and adapt to these differences and changes.

 

Osteoporosis and its complications ranked first in the space of disease risk.

  

Long-term health risks associated with flying Topics

  

The degree of influence long-term biological effects of radiation in human flight can withstand the radiation and the maximum limit of accumulated radiation on physiology, pathology and genetics.

 

Physiological effects of weightlessness including: long-term bone loss and a return flight after the maximum extent and severity of the continued deterioration of other pathological problems induced by the; maximum flexibility and severity of possible long-term Flight Center in vascular function.

 

Long-term risk of disease due to the high risk of flight stress, microbial variation, decreased immune function, leading to infections

 

Radiation hazards and protection

    

1) radiation medicine, biology and pathway effects Features

  

Radiation protection for interplanetary flight, since the lack of protective effect of Earth's magnetic field, and by the irradiation time is longer, the possibility of increased radiation hazard.

       

Analysis of space flight medical problems that may occur, loss of appetite topped the list, sleep disorders, fatigue and insomnia, in addition, space sickness, musculoskeletal system problems, eye problems, infections problems, skin problems and cardiovascular problems

  

---------------------------------------------------------

  

Development of diagnostic techniques in orbit, the development of the volume of power consumption, features a wide range of diagnostic techniques, such as applied research of ultrasound diagnostic techniques in the abdominal thoracic trauma, bone, ligament damage, dental / sinus infections and other complications and integrated;

 

Actively explore in orbit disposal of medical technology, weightlessness surgical methods, development of special surgical instruments, the role of narcotic drugs and the like.

  

——————————————————————————————-

 

However, space technology itself is integrated with the use of the most advanced technology, its challenging technical reserves and periodic demanding

 

With the continuous development of science and technology, space agencies plan a manned landing on the moon and Mars, space exploration emergency medicine current concern.

 

Space sickness

  

In the weightless environment of space, in the weightless environment of space, surgery may be extremely difficult and risky.

  

Robot surgeons

 

Space disease in three days after entering the space started to ease, although individual astronauts might subsequently relapse. January 2015 NASA declared working on a fast, anti-nausea and nasal sprays. In addition, due to the zero-gravity environment, and anti-nausea drugs can only be administered by injection or transdermal patches manner.

        

Manned spaceflight in the 21st century is the era of interplanetary flight, aerospace medicine is closely watched era is the era of China's manned space flourish. Only the central issue, and grasp the opportunity to open up a new world of human survival and development.

 

Various emergency contingency measures in special circumstances. Invisible accident risk prevention. Enhancing drugs and other screening methods immunity aerospace medicine and tissue engineering a microgravity environment. Drug mixture of APS, ginseng polysaccharides, Ganoderma lucidum polysaccharides, polysaccharides and Lentinan, from other compounds. Drug development space syndrome drug, chemical structure modification will be an important part.

These issues are very sensitive, cutting-edge technology is a major difficulty landing on Mars. Countries in the world, especially the world's major space powers in the country strategies and technical research, the results of all kinds continue to emerge. United States, Russia, China, Europe, India, Japan and other countries is different. United States, Russia extraordinary strength. Many patented technology and health, and most belong to the top-secret technology. Especially in aerospace engineering and technological achievements is different from the general scientific literature, practical, commercial, industrial great, especially the performance of patents, know-how, technical drawings, engineering design and other aspects. Present Mars and return safely to Earth, the first manned, significance, everything is hard in the beginning, especially the first person to land on Mars This Mars for Human Sciences Research Mars, the moon, the earth, the solar system and the universe, life and other significant. Its far greater than the value of direct investments and business interests.

 

In addition, it is the development of new materials, suitable for deep space operations universe, life, and other detection, wider field.

Many aerospace materials, continuous research and development of materials are key areas of aerospace development, including material rocket, the spacecraft materials, the suit materials, radiation materials, materials and equipment, instruments, materials and so on biochemistry.

Temperature metal-based compound with a metal matrix composite body with a more primordial higher temperature strength, creep resistance, impact resistance, thermal fatigue and other excellent high temperature performance.

In B, C, SiC fiber reinforced Ti3Al, TiAl, Ni3Al intermetallic matrix composites, etc.

W Fiber Reinforced with nickel-based, iron-based alloys as well as SiC, TiB2, Si3N4 and BN particle reinforced metal matrix composites

High temperature service conditions require the development of ceramic and carbon-based composite materials, etc., not in this eleven Cheung said.

  

Fuel storage

  

In order to survive in space, people need many things: food, oxygen, shelter, and, perhaps most importantly, fuel. The initial quality Mars mission somewhere around 80 percent of the space launch humans will be propellant. The fuel amount of storage space is very difficult.

  

This difference in low Earth orbit cause liquid hydrogen and liquid oxygen - rocket fuel - vaporization.

Hydrogen is particularly likely to leak out, resulting in a loss of about 4% per month.

  

When you want to get people to Mars speed to minimize exposure to weightlessness and space radiation hazards

 

Mars

 

Landings on the Martian surface, they realized that they reached the limit. The rapid expansion of the thin Martian atmosphere can not be very large parachute, such as those that will need to be large enough to slow down, carry human spacecraft.

Therefore, the parachute strong mass ratio, high temperature resistance, Bing shot performance and other aspects of textile materials used have special requirements, in order to make a parachute can be used in rockets, missiles, Yu arrows spacecraft and other spacecraft recovery, it is necessary to improve the canopy heat resistance, a high melting point polymeric fiber fabric used, the metal fabric, ceramic fiber fabrics, and other devices.

  

Super rigid parachute to help slow the landing vehicle.

Spacecraft entered the Martian atmosphere at 24,000 km / h. Even after slowing parachute or inflatable, it will be very

  

Once we have the protection of the Earth magnetic field, the solar radiation will accumulate in the body, a huge explosion threw the spacecraft may potentially lethal doses of radiation astronauts.

  

In addition to radiation, the biggest challenge is manned trip to Mars microgravity, as previously described.

  

The moon is sterile. Mars is another case entirely.

 

With dust treatment measures.

  

Arid Martian environment to create a super-tiny dust particles flying around the Earth for billions of years.

 

Apollo moon dust encountered. Ultra-sharp and abrasive lunar dust was named something that can clog the basic functions of mechanical damage. High chloride salt, which can cause thyroid problems in people.

 

*** Mars geological structure and geological structure of the moon, water on Mars geology, geology of the Moon is very important, because he, like the Earth's geology is related to many important issues. Water, the first element of life, air, temperature, and complex geological formations are geological structure. Cosmic geology research methods, mainly through a variety of detection equipment equipped with a space probe, celestial observations of atmospheric composition, composition and distribution of temperature, pressure, wind speed, vertical structure, composition of the solar wind, the water, the surface topography and Zoning, topsoil the composition and characteristics of the component surface of the rock, type and distribution, stratigraphic sequence, structural system and the internal shell structure.

 

Mars internal situation only rely on its surface condition of large amounts of data and related information inferred. It is generally believed that the core radius of 1700 km of high-density material composition; outsourcing a layer of lava, it is denser than the Earth's mantle some; outermost layer is a thin crust. Compared to other terrestrial planets, the lower the density of Mars, which indicates that the Martian core of iron (magnesium and iron sulfide) with may contain more sulfur. Like Mercury and the Moon, Mars and lack active plate movement; there is no indication that the crust of Mars occurred can cause translational events like the Earth like so many of folded mountains. Since there is no lateral movement in the earth's crust under the giant hot zone relative to the ground in a stationary state. Slight stress coupled with the ground, resulting in Tharis bumps and huge volcano. For the geological structure of Mars is very important, which is why repeated explorations and studies of Martian geological reasons.

Core

Mars is about half the radius of the core radius, in addition to the primary iron further comprises 15 to 17% of the sulfur content of lighter elements is also twice the Earth, so the low melting point, so that the core portion of a liquid, such as outside the Earth nuclear.

 

Mantle

Nuclear outer coating silicate mantle.

 

Crust

The outermost layer of the crust.

Crustal thickness obtained, the original thickness of the low north 40 km south plateau 70 kilometers thick, an average of 50 kilometers, at least 80 km Tharsis plateau and the Antarctic Plateau, and in the impact basin is thin, as only about 10 kilometers Greece plains.

  

Canyon of Mars there are two categories: outflow channels (outflow channel) and tree valley (valley network). The former is very large, it can be 100 km wide, over 2000 km long, streamlined, mainly in the younger Northern Hemisphere, such as the plain around Tyre Chris Canyon and Canyon jam.

 

In addition, the volcanic activity sometimes lava formation lava channels (lava channel); crustal stress generated by fissures, faults, forming numerous parallel extending grooves (fossa), such as around the huge Tharsis volcanic plateau radially distributed numerous grooves, which can again lead to volcanic activity.

  

Presumably, Mars has an iron as the main component of the nucleus, and contains sulfur, magnesium and other light elements, the nuclear share of Mars, the Earth should be relatively small. The outer core is covered with a thick layer of magnesium-rich silicate mantle, the surface of rocky crust. The density of Earth-like planets Mars is the lowest, only 3.93g / cc.

Lunar core

The average density of the Moon is 3.3464 g / cc, the solar system satellites second highest (after Aiou). However, there are few clues mean lunar core is small, only about 350 km radius or less [2]. The core of the moon is only about 20% the size of the moon, the moon's interior has a solid, iron-rich core diameter of about 240 kilometers (150 miles); in addition there is a liquid core, mainly composed of iron outer core, about 330 km in diameter (205 miles), and for the first time compared with the core of the Earth, considered as the earth's outer core, like sulfur and oxygen may have lighter elements [4].

 

Chemical elements on the lunar surface constituted in accordance with its abundance as follows: oxygen (O), silicon (Si), iron (Fe), magnesium (Mg), calcium (Ca), aluminum (Al), manganese (Mn), titanium ( Ti). The most abundant is oxygen, silicon and iron. The oxygen content is estimated to be 42% (by weight). Carbon (C) and nitrogen (N) only traces seem to exist only in trace amounts deposited in the solar wind brings.

Moon geological history is an important event in recent global magma ocean crystallization. The specific depth is not clear, but some studies have shown that at least a depth of about 500 kilometers or more.

 

Lunar landscape

Lunar landscape can be described as impact craters and ejecta, some volcanoes, hills, lava-filled depressions.

  

Regolith

TABLE bear the asteroid and comets billions of years of bombardment. Over time, the impact of these processes have already broken into fine-grained surface rock debris, called regolith. Young mare area, regolith thickness of about 2 meters, while the oldest dated land, regolith thickness of up to 20 meters. Through the analysis of lunar soil components, in particular the isotopic composition changes can determine the period of solar activity. Solar wind gases possible future lunar base is useful because oxygen, hydrogen (water), carbon and nitrogen is not only essential to life, but also may be useful for fuel production. Lunar soil constituents may also be as a future source of energy.

Here, repeatedly stressed that the geological structure and geological structure of celestial bodies, the Earth, Moon, Mars, or that this human existence and development of biological life forms is very important, especially in a series of data Martian geological structure geological structure is directly related to human landing Mars and the successful transformation of Mars or not. for example, water, liquid water, water, oxygen, synthesis, must not be taken lightly.

Mars landing 10 Technology

 

Aerospace Science and space science and technology major innovation of the most critical of sophisticated technology R & D project

  

[

"1" rocket propulsion technology ion fusion nuclear pulse propulsion rocket powered high-speed heavy rocket technology, space nuclear reactors spacecraft] brought big problems reflected in the nuclear reaction, nuclear radiation on spacecraft launch, control, brakes and other impact.

In particular, for the future of nuclear power spacecraft, the need to solve the nuclear reactor design, manufacture, control, cooling, radiation shielding, exhaust pollution, high thermoelectric conversion efficiency and a series of technical problems.

In particular, nuclear reactors produce radiation on astronauts' health will pose a great threat, which requires the spacecraft to be nuclear radiation shielding to ensure astronaut and ship the goods from radiation and heat from the reactor influence, but this will greatly increase the weight of the detector.

Space nuclear process applications, nuclear reaction decay is not a problem, but in a vacuum, ultra-low temperature environment, the nuclear reaction materials, energy transport materials have very high demands.

Space facing the reality of a nuclear reactor cooling cooling problems. To prevent problems with the reactor, "Washington" aircraft carrier to take four heavy protective measures for the radiation enclosed in the warship. These four measures are: the fuel itself, fuel storage pressure vessel, reactor shell and the hull. US Navy fuel all metal fuel, designed to take the impact resistance of the war, does not release fission product can withstand more than 50 times the gravity of the impact load; product of nuclear fission reactor fuel will never enter loop cooling water. The third layer of protection is specially designed and manufactured the reactor shell. The fourth layer is a very strong anti-impact combat ship, the reactor is arranged in the center of the ship, very safe. Engage in a reactor can only be loaded up to the aircraft, so as to drive the motor, and then drive the propeller. That is the core advantage of the heat generated by the heated gas flow, high temperature high pressure gas discharge backward, thereby generating thrust.

After installation AMPS1000 type nuclear power plant, a nuclear fuel assembly: He is a core member of the nuclear fuel chain reaction. Usually made into uranium dioxide, of which only a few percent uranium-235, and most of it is not directly involved in the nuclear fission of uranium 238. The uranium dioxide sintered into cylindrical pieces, into a stainless steel or a zirconium alloy do metal tubes called fuel rods or the original, then the number of fuel rods loaded metal cylinder in an orderly composition of the fuel assembly, and finally put a lot of vertical distribution of fuel assemblies in the reactor.

 

Nuclear reactor pressure vessel is a housing for containing nuclear fuel and reactor internals, for producing high-quality high-strength steel is made to withstand the pressure of dozens MPa. Import and export of the coolant in the pressure vessel.

 

The top of the pressure vessel closure, and can be used to accommodate the fixed control rod drive mechanism, pressure vessel head has a semi-circular, flat-topped.

 

Roof bolt: used to connect the locking pressure vessel head, so that the cylinder to form a completely sealed container.

  

Neutron Source: Plug in nuclear reactors can provide sufficient neutron, nuclear fuel ignition, to start to enhance the role of nuclear reactors and nuclear power. Neutron source generally composed of radium, polonium, beryllium, antimony production. Neutron source and neutron fission reactors are fast neutron, can not cause fission of uranium 235, in order to slow down, we need to moderator ---- full of pure water in a nuclear reactor. Aircraft carriers, submarines use nuclear reactor control has proven more successful.

 

Rod: has a strong ability to absorb neutrons, driven by the control rod drive mechanism, can move up and down in a nuclear reactor control rods within the nuclear fuel used to start, shut down the nuclear reactor, and maintain, regulate reactor power. Hafnium control rods in general, silver, indium, cadmium and other metals production.

 

Control rod drive mechanism: He is the executive body of nuclear reactors operating system and security protection systems, in strict accordance with requirements of the system or its operator control rod drives do move up and down in a nuclear reactor, nuclear reactor for power control. In a crisis situation, you also can quickly control rods fully inserted into the reactor in order to achieve the purpose of the emergency shutdown

 

Upper and lower support plate: used to secure the fuel assembly. High temperature and pressure inside the reactor is filled with pure water (so called pressurized water reactors), on the one hand he was passing through a nuclear reactor core, cooling the nuclear fuel, to act as a coolant, on the other hand it accumulates in the pressure vessel in play moderated neutrons role, acting as moderator.

  

Water quality monitoring sampling system:

Adding chemical system: under normal circumstances, for adding hydrazine, hydrogen, pH control agents to the primary coolant system, the main purpose is to remove and reduce coolant oxygen, high oxygen water suppression equipment wall corrosion (usually at a high temperature oxygen with hydrogen, especially at low temperatures during startup of a nuclear reactor with added hydrazine oxygen); when the nuclear reactor control rods stuck for some reason can not shutdown time by the the system can inject the nuclear reactor neutron absorber (such as boric acid solution), emergency shutdown, in order to ensure the safety of nuclear submarines.

 

Water system: a loop inside the water will be reduced at work, such as water sampling and analysis, equipment leaks, because the shutdown process cooling water and reduction of thermal expansion and contraction.

 

Equipment cooling water system:

Pressure safety systems: pressure reactor primary coolant system may change rapidly for some reason, the need for effective control. And in severe burn nuclear fuel rods, resulting in a core melt accident, it is necessary to promptly increase the pressure. Turn the regulator measures the electric, heating and cooling water. If necessary, also temporary startup booster pump.

 

Residual Heat Removal System: reactor scram may be due to an accident, such as when the primary coolant system of the steam generator heat exchanger tube is damaged, it must be urgently closed reactors.

 

Safety Injection System: The main components of this system is the high-pressure injection pump.

 

Radioactive waste treatment systems:

 

Decontamination Systems: for the removal of radioactive deposits equipment, valves, pipes and accessories, and other surfaces.

 

Europe, the United States and Russia and other countries related to aircraft carriers, submarines, icebreakers, nuclear-powered research aircraft, there are lots of achievements use of nuclear energy, it is worth analysis. However, nuclear reactor technology, rocket ships and the former are very different, therefore, requires special attention and innovative research. Must adopt a new new design techniques, otherwise, fall into the stereotype, it will avail, nothing even cause harm Aerospace.

Aerospace Science and space science and technology major innovation of the most critical of sophisticated technology R & D project

-------------------------------------------------- -------------

Aerospace Science Space Science and Technology on behalf of the world's most cutting-edge leader in high technology, materials, mechatronics, information and communication, energy, biomedical, marine, aviation aerospace, microelectronics, computer, automation, intelligent biochips, use of nuclear energy, light mechanical and electrical integration, astrophysics, celestial chemistry, astrophysics and so a series of geological science and technology. Especially after the moon landing, the further development of mankind to Mars and other planets into the powerful offensive, the world's major powers eager to Daxian hand of God, increase investment, vigorously develop new sophisticated technology projects for space to space. Satellite, space station, the new spacecraft, the new space suits, the new radiation protection materials, intelligent materials, new manufacturing technology, communications technology, computer technology, detector technology, rover, rover technology, biomedical technology, and so one after another, is expected to greater breakthroughs and leaps. For example, rocket technology, spacecraft design, large power spacecraft, spacesuits design improvements, radiation multifunctional composite materials, life health care technology and space medicine, prevention against microgravity microgravity applicable drugs, tracking control technology, landing and return technology. Mars lander and returned safely to Earth as a top priority. Secondly, Mars, the Moon base and the use of transforming Mars, the Moon and other development will follow. Whether the former or the latter, are the modern aerospace science, space science basic research, applied basic research and applied research in the major cutting-edge technology. These major cutting-edge technology research and innovation, not only for human landing on Mars and the safe return of great significance, but for the entire space science, impact immeasurable universe sciences, earth sciences and human life. Here the most critical of the most important research projects of several sophisticated technology research and development as well as its core technology brief. Limit non-scientific techniques include non-technical limits of technology, the key lies in technology research and development of technology maturity, advanced technology, innovative, practical, reliable, practical application, business value and investment costs, and not simply like the idea mature technology achievements, difficult to put into things. This is the high-tech research and development, testing, prototype, test application testing, until the outcome of industrialization. Especially in aerospace technology, advanced, novelty, practicality, reliability, economy, maturity, commercial value and so on. For technical and research purely science fiction and the like may be irrelevant depth, but not as aerospace engineering and technology practice. Otherwise, Mars will become a dream fantasy, and even into settling crashed out of danger.

 

Regardless of the moon or Mars, many technical difficulties, especially a human landing on Mars and return safely to Earth, technical difficulties mainly in the following aspects. (Transformation of Mars and the Moon and other planets and detect other livable technology more complex and difficult, at this stage it is difficult to achieve and therefore not discussed in detail in this study). In fact, Mars will be the safe return of a full set of technology, space science, aerospace crucial scientific research development, its significance is not confined to Mars simply a return to scientific value, great commercial value, can not be measure.

1. Powered rocket, the spacecraft overall structural design not be too complex large, otherwise, the safety factor to reduce the risk of failure accidents. Fusion rocket engine main problem to be solved is the high-temperature materials and fuel ignition chamber (reaction chamber temperatures of up to tens of millions of supreme billion degrees), fissile class rocket engine whose essence is the miniaturization of nuclear reactors, and placed on the rocket. Nuclear rocket engine fuel as an energy source, with liquid hydrogen, liquid helium, liquid ammonia working fluid. Nuclear rocket engine mounted in the thrust chamber of the reactor, cooling nozzle, the working fluid delivery and control systems and other components. This engine due to nuclear radiation protection, exhaust pollution, reactor control and efficient heat exchanger design and other issues unresolved. Electrothermal rocket engine utilizing heat energy (resistance heating or electric arc heating) working medium (hydrogen, amines, hydrazine ), vaporized; nozzle expansion accelerated after discharged from the spout to generate thrust. Static rocket engine working fluid (mercury, cesium, hydrogen, etc.) from the tank enter the ionization chamber is formed thrust ionized into a plasma jet. Electric rocket engines with a high specific impulse (700-2500 sec), extremely long life (can be repeated thousands of times a starter, a total of up to thousands of hours of work). But the thrust of less than 100N. This engine is only available for spacecraft attitude control, station-keeping and the like. One nuclear - power rocket design is as follows: Firstly, the reactor heats water to make it into steam, and then the high-speed steam ejected, push the rocket. Nuclear rocket using hydrogen as working substance may be a better solution, it is one of the most commonly used liquid hydrogen rocket fuel rocket carrying liquid hydrogen virtually no technical difficulties. Heating hydrogen nuclear reactor, as long as it eventually reaches or exceeds current jet velocity hydrogen rocket engine jet speed, the same weight of the rocket will be able to work longer, it can accelerate the Rockets faster. Here there are only two problems: First, the final weight includes the weight of the rocket in nuclear reactors, so it must be as light as possible. Ultra-small nuclear reactor has been able to achieve. Furthermore, if used in outer space, we can not consider the problem of radioactive residues, simply to just one proton hydrogen nuclei are less likely to produce induced radioactivity, thus shielding layer can be made thinner, injected hydrogen gas can flow directly through the reactor core, it is not easy to solve, and that is how to get back at high speed heated gas is ejected.

  

Rocket engine with a nuclear fission reactor, based on the heating liquid hydrogen propellant, rather than igniting flammable propellant

High-speed heavy rocket is a major cutting-edge technology. After all, space flight and aircraft carriers, submarines, nuclear reactors differ greatly from the one hand, the use of traditional fuels, on the one hand can be nuclear reactor technology. From the control, for security reasons, the use of nuclear power rocket technology, safe and reliable overriding indicators. Nuclear atomic energy in line with the norms and rules of outer space. For the immature fetal abdominal hatchery technology, and resolutely reject use. This is the most significant development of nuclear-powered rocket principle.

Nuclear-powered spaceship for Use of nuclear power are three kinds:

The first method: no water or air space such media can not be used propeller must use jet approach. Reactor nuclear fission or fusion to produce a lot of heat, we will propellant (such as liquid hydrogen) injection, the rapid expansion of the propellant will be heated and then discharged from the engine speed tail thrust. This method is most readily available.

The second method: nuclear reactor will have a lot of fast-moving ions, these energetic particles moving very fast, so you can use a magnetic field to control their ejection direction. This principle ion rocket similar to the tail of the rocket ejected from the high-speed mobile ions, so that the recoil movement of a rocket. The advantage of this approach is to promote the unusually large ratio, without carrying any medium, continued strong. Ion engine, which is commonly referred to as "electric rocket", the principle is not complicated, the propellant is ionized particles,

Plasma Engine

Electromagnetic acceleration, high-speed spray. From the development trend, the US research scope covers almost all types of electric thrusters, but mainly to the development of ion engines, NASA in which to play the most active intake technology and preparedness plans. "

The third method: the use of nuclear explosions. It is a bold and crazy way, no longer is the use of a controlled nuclear reaction, but to use nuclear explosions to drive the ship, this is not an engine, and it is called a nuclear pulse rocket. This spacecraft will carry a lot of low-yield atomic bombs out one behind, and then detonated, followed by a spacecraft propulsion installation disk, absorbing the blast pushing the spacecraft forward. This was in 1955 to Orion (Project Orion) name of the project, originally planned to bring two thousand atomic bombs, Orion later fetal nuclear thermal rocket. Its principle is mounted on a small rocket reactor, the reactor utilizing thermal energy generated by the propellant is heated to a high temperature, high pressure and high temperature of the propellant from the high-speed spray nozzle, a tremendous impetus.

  

Common nuclear fission technologies, including nuclear pulse rocket engines, nuclear rockets, nuclear thermal rocket and nuclear stamping rockets to nuclear thermal rocket, for example, the size of its land-based nuclear power plant reactor structure than the much smaller, more uranium-235 purity requirements high, reaching more than 90%, at the request of the high specific impulse engine core temperature will reach about 3000K, require excellent high temperature properties of materials.

  

Research and test new IT technologies and new products and new technology and new materials, new equipment, things are difficult, design is the most important part, especially in the overall design, technical solutions, technical route, technical process, technical and economic particularly significant. The overall design is defective, technology there are loopholes in the program, will be a major technical route deviation, but also directly related to the success of research trials. so, any time, under any circumstances, a good grasp of the overall control of design, technical design, is essential. otherwise, a done deal, it is difficult save. aerospace technology research and product development is true.

  

3, high-performance nuclear rocket

Nuclear rocket nuclear fission and fusion energy can rocket rocket two categories. Nuclear fission and fusion produce heat, radiation and shock waves and other large amounts of energy, but here they are contemplated for use as a thermal energy rocket.

Uranium and other heavy elements, under certain conditions, will split their nuclei, called nuclear fission reaction. The atomic bomb is the result of nuclear fission reactions. Nuclear fission reaction to release energy, is a million times more chemical rocket propellant combustion energy. Therefore, nuclear fission energy is a high-performance rocket rockets. Since it requires much less propellant than chemical rockets can, so to its own weight is much lighter than chemical rockets energy. For the same quality of the rocket, the rocket payload of nuclear fission energy is much greater than the chemical energy of the rocket. Just nuclear fission energy rocket is still in the works. 

Use of nuclear fission energy as the energy of the rocket, called the atomic rockets. It is to make hydrogen or other inert gas working fluid through the reactor, the hydrogen after the heating temperature quickly rose to 2000 ℃, and then into the nozzle, high-speed spray to produce thrust. 

A vision plan is to use liquid hydrogen working fluid, in operation, the liquid hydrogen tank in the liquid hydrogen pump is withdrawn through the catheter and the engine cooling jacket and liquid hydrogen into hydrogen gas, hydrogen gas turbine-driven, locally expansion. Then by nuclear fission reactors, nuclear fission reactions absorb heat released, a sharp rise in temperature, and finally into the nozzle, the rapid expansion of high-speed spray. Calculations show that the amount of atomic payload rockets, rocket high chemical energy than 5-8 times.

Hydrogen and other light elements, under certain conditions, their nuclei convergent synthesis of new heavy nuclei, and release a lot of energy, called nuclear fusion reaction, also called thermonuclear reaction. 

Using energy generated by the fusion reaction for energy rocket, called fusion energy rocket or nuclear thermal rockets. But it is also not only take advantage of controlled nuclear fusion reaction to manufacture hydrogen bombs, rockets and controlled nuclear fusion reaction needs still studying it.

Of course there are various research and development of rocket technology and technical solutions to try.

It is envisaged that the rocket deuterium, an isotope of hydrogen with deuterium nuclear fusion reaction of helium nuclei, protons and neutrons, and release huge amounts of energy, just polymerized ionized helium to temperatures up to 100 million degrees the plasma, and then nozzle expansion, high-speed ejection, the exhaust speed of up to 15,000 km / sec, atomic energy is 1800 times the rocket, the rocket is the chemical energy of 3700 times.

 

Nuclear rocket engine fuel as an energy source, with liquid hydrogen, liquid helium, liquid ammonia working fluid. Nuclear rocket engine mounted in the thrust chamber of the reactor, cooling nozzle, the working fluid delivery and control systems and other components. In a nuclear reactor, nuclear energy into heat to heat the working fluid, the working fluid is heated after expansion nozzle to accelerate to the speed of 6500 ~ 11,000 m / sec from the discharge orifice to produce thrust. Nuclear rocket engine specific impulse (250 to 1000 seconds) long life, but the technology is complex, apply only to long-term spacecraft. This engine due to nuclear radiation protection, exhaust pollution, reactor control and efficient heat exchanger design and other issues not resolved, is still in the midst of trials. Nuclear rocket technology is cutting-edge aerospace science technology, centralized many professional and technical sciences and aerospace, nuclear physics, nuclear chemistry, materials science, the long term future ___-- wide width. The United States, Russia and Europe, China, India, Japan, Britain, Brazil and other countries in this regard have studies, in particular the United States and Russia led the way, impressive. Of course, at this stage of nuclear rocket technology, technology development there are still many difficulties. Fully formed, still to be. But humanity marching to the universe, nuclear reactor applications is essential.

Any space exploration are inseparable from the energy battery is a new super hybrid energy storage device, the asymmetric lead-acid batteries and supercapacitors in the same compound within the system - and the so-called inside, no additional separate electronic control unit, this is an optimal combination. The traditional lead-acid battery PbO2 monomer is a positive electrode plate and a negative electrode plate spongy Pb composition, not a super cell. : Silicon solar cells, multi-compound thin film solar cells, multi-layer polymer-modified electrode solar cells, nano-crystalline solar cells, batteries and super class. For example, the solar aircraft .10. To protect the health and life safety and security systems. Lysophosphatidic acid LPA is a growth factor-like lipid mediators, the researchers found that this substance can on apoptosis after radiation injury and animal cells was inhibited. Stable lysophosphatidic acid analogs having the hematopoietic system and gastrointestinal tract caused by acute radiation sickness protection, knockout experiments show that lysophosphatidic acid receptors is an important foundation for the protection of radiation injury. In addition to work under high pressure, the astronauts face a number of health threats, including motion sickness, bacterial infections, blindness space, as well as psychological problems, including toxic dust. In the weightless environment of space, the astronaut's body will be like in preadolescents, as the emergence of various changes.

Plantar molt

After the environment to adapt to zero gravity, the astronaut's body will be some strange changes. Weightlessness cause fluid flow around the main flow torso and head, causing the astronauts facial swelling and inflammation, such as nasal congestion. During long-term stay in space

 

Bone and muscle loss

Most people weightlessness caused by the impact may be known bone and muscle degeneration. In addition, the calcium bones become very fragile and prone to fracture, which is why some of the astronauts after landing need on a stretcher.

Space Blindness

Space Blindness refers astronaut decreased vision.

Solar storms and radiation is one of the biggest challenges facing the long-term space flight. Since losing the protection of Earth's magnetic field, astronauts suffer far more than normal levels of radiation. The cumulative amount of radiation exposure in low earth orbit them exceeded by workers close to nuclear reactors, thereby increasing the risk of cancer.

Prolonged space flight can cause a series of psychological problems, including depression or mood swings, vulnerability, anxiety and fear, as well as other sequelae. We are familiar with the biology of the Earth, the Earth biochemistry, biophysics, after all, the Earth is very different astrophysics, celestial chemistry, biophysics and astrophysics, biochemistry and other celestial bodies. Therefore, you must be familiar with and adapt to these differences and changes.

 

Osteoporosis and its complications ranked first in the space of disease risk.

  

Long-term health risks associated with flying Topics

However, space technology itself is integrated with the use of the most advanced technology, its challenging technical reserves and periodic demanding

 

With the continuous development of science and technology, space agencies plan a manned landing on the moon and Mars, space exploration emergency medicine current concern.

 

Space sickness

  

In the weightless environment of space, in the weightless environment of space, surgery may be extremely difficult and risky.

  

Robot surgeons

 

Space disease in three days after entering the space started to ease, although individual astronauts might subsequently relapse. January 2015 NASA declared working on a fast, anti-nausea and nasal sprays. In addition, due to the zero-gravity environment, and anti-nausea drugs can only be administered by injection or transdermal patches manner.

        

Manned spaceflight in the 21st century is the era of interplanetary flight, aerospace medicine is closely watched era is the era of China's manned space flourish. Only the central issue, and grasp the opportunity to open up a new world of human survival and development.

 

Various emergency contingency measures in special circumstances. Invisible accident risk prevention. Enhancing drugs and other screening methods immunity aerospace medicine and tissue engineering a microgravity environment. Drug mixture of APS, ginseng polysaccharides, Ganoderma lucidum polysaccharides, polysaccharides and Lentinan, from other compounds. Drug development space syndrome drug, chemical structure modification will be an important part.

These issues are very sensitive, cutting-edge technology is a major difficulty landing on Mars. Countries in the world, especially the world's major space powers in the country strategies and technical research, the results of all kinds continue to emerge. United States, Russia, China, Europe, India, Japan and other countries is different. United States, Russia extraordinary strength. Many patented technology and health, and most belong to the top-secret technology. Especially in aerospace engineering and technological achievements is different from the general scientific literature, practical, commercial, industrial great, especially the performance of patents, know-how, technical drawings, engineering design and other aspects. Present Mars and return safely to Earth, the first manned, significance, everything is hard in the beginning, especially the first person to land on Mars This Mars for Human Sciences Research Mars, the moon, the earth, the solar system and the universe, life and other significant. Its far greater than the value of direct investments and business interests.

 

In addition, it is the development of new materials, suitable for deep space operations universe, life, and other detection, wider field.

Many aerospace materials, continuous research and development of materials are key areas of aerospace development, including material rocket, the spacecraft materials, the suit materials, radiation materials, materials and equipment, instruments, materials and so on biochemistry.

W Fiber Reinforced with nickel-based, iron-based alloys as well as SiC, TiB2, Si3N4 and BN particle reinforced metal matrix composites

High temperature service conditions require the development of ceramic and carbon-based composite materials, etc., not in this eleven Cheung said.

  

Fuel storage

  

In order to survive in space, people need many things: food, oxygen, shelter, and, perhaps most importantly, fuel. The initial quality Mars mission somewhere around 80 percent of the space launch humans will be propellant. The fuel amount of storage space is very difficult.

  

This difference in low Earth orbit cause liquid hydrogen and liquid oxygen - rocket fuel - vaporization.

Hydrogen is particularly likely to leak out, resulting in a loss of about 4% per month.

  

When you want to get people to Mars speed to minimize exposure to weightlessness and space radiation hazards

 

Mars

 

Landings on the Martian surface, they realized that they reached the limit. The rapid expansion of the thin Martian atmosphere can not be very large parachute, such as those that will need to be large enough to slow down, carry human spacecraft.

Therefore, the parachute strong mass ratio, high temperature resistance, Bing shot performance and other aspects of textile materials used have special requirements, in order to make a parachute can be used in rockets, missiles, Yu arrows spacecraft and other spacecraft recovery, it is necessary to improve the canopy heat resistance, a high melting point polymeric fiber fabric used, the metal fabric, ceramic fiber fabrics, and other devices.

  

Super rigid parachute to help slow the landing vehicle.

Spacecraft entered the Martian atmosphere at 24,000 km / h. Even after slowing parachute or inflatable, it will be very

  

Once we have the protection of the Earth magnetic field, the solar radiation will accumulate in the body, a huge explosion threw the spacecraft may potentially lethal doses of radiation astronauts.

  

In addition to radiation, the biggest challenge is manned trip to Mars microgravity, as previously described.

  

The moon is sterile. Mars is another case entirely.

 

With dust treatment measures.

  

Arid Martian environment to create a super-tiny dust particles flying around the Earth for billions of years.

 

Apollo moon dust encountered. Ultra-sharp and abrasive lunar dust was named something that can clog the basic functions of mechanical damage. High chloride salt, which can cause thyroid problems in people.

 

*** Mars geological structure and geological structure of the moon, water on Mars geology, geology of the Moon is very important, because he, like the Earth's geology is related to many important issues. Water, the first element of life, air, temperature, and complex geological formations are geological structure. Cosmic geology research methods, mainly through a variety of detection equipment equipped with a space probe, celestial observations of atmospheric composition, composition and distribution of temperature, pressure, wind speed, vertical structure, composition of the solar wind, the water, the surface topography and Zoning, topsoil the composition and characteristics of the component surface of the rock, type and distribution, stratigraphic sequence, structural system and the internal shell structure.

 

Mars internal situation only rely on its surface condition of large amounts of data and related information inferred. It is generally believed that the core radius of 1700 km of high-density material composition; outsourcing a layer of lava, it is denser than the Earth's mantle some; outermost layer is a thin crust. Compared to other terrestrial planets, the lower the density of Mars, which indicates that the Martian core of iron (magnesium and iron sulfide) with may contain more sulfur. Like Mercury and the Moon, Mars and lack active plate movement; there is no indication that the crust of Mars occurred can cause translational events like the Earth like so many of folded mountains. Since there is no lateral movement in the earth's crust under the giant hot zone relative to the ground in a stationary state. Slight stress coupled with the ground, resulting in Tharis bumps and huge volcano. For the geological structure of Mars is very important, which is why repeated explorations and studies of Martian geological reasons.

Crust

The outermost layer of the crust.

Crustal thickness obtained, the original thickness of the low north 40 km south plateau 70 kilometers thick, an average of 50 kilometers, at least 80 km Tharsis plateau and the Antarctic Plateau, and in the impact basin is thin, as only about 10 kilometers Greece plains.

  

Canyon of Mars there are two categories: outflow channels (outflow channel) and tree valley (valley network). The former is very large, it can be 100 km wide, over 2000 km long, streamlined, mainly in the younger Northern Hemisphere, such as the plain around Tyre Chris Canyon and Canyon jam.

 

In addition, the volcanic activity sometimes lava formation lava channels (lava channel); crustal stress generated by fissures, faults, forming numerous parallel extending grooves (fossa), such as around the huge Tharsis volcanic plateau radially distributed numerous grooves, which can again lead to volcanic activity.

  

Presumably, Mars has an iron as the main component of the nucleus, and contains sulfur, magnesium and other light elements, the nuclear share of Mars, the Earth should be relatively small. The outer core is covered with a thick layer of magnesium-rich silicate mantle, the surface of rocky crust. The density of Earth-like planets Mars is the lowest, only 3.93g / cc.

Lunar core

The average density of the Moon is 3.3464 g / cc, the solar system satellites second highest (after Aiou). However, there are few clues mean lunar core is small, only about 350 km radius or less [2]. The core of the moon is only about 20% the size of the moon, the moon's interior has a solid, iron-rich core diameter of about 240 kilometers (150 miles); in addition there is a liquid core, mainly composed of iron outer core, about 330 km in diameter (205 miles), and for the first time compared with the core of the Earth, considered as the earth's outer core, like sulfur and oxygen may have lighter elements [4].

 

Chemical elements on the lunar surface constituted in accordance with its abundance as follows: oxygen (O), silicon (Si), iron (Fe), magnesium (Mg), calcium (Ca), aluminum (Al), manganese (Mn), titanium ( Ti). The most abundant is oxygen, silicon and iron. The oxygen content is estimated to be 42% (by weight). Carbon (C) and nitrogen (N) only traces seem to exist only in trace amounts deposited in the solar wind brings.

Moon geological history is an important event in recent global magma ocean crystallization. The specific depth is not clear, but some studies have shown that at least a depth of about 500 kilometers or more.

 

Lunar landscape

Lunar landscape can be described as impact craters and ejecta, some volcanoes, hills, lava-filled depressions.

  

Regolith

TABLE bear the asteroid and comets billions of years of bombardment. Over time, the impact of these processes have already broken into fine-grained surface rock debris, called regolith. Young mare area, regolith thickness of about 2 meters, while the oldest dated land, regolith thickness of up to 20 meters. Through the analysis of lunar soil components, in particular the isotopic composition changes can determine the period of solar activity. Solar wind gases possible future lunar base is useful because oxygen, hydrogen (water), carbon and nitrogen is not only essential to life, but also may be useful for fuel production. Lunar soil constituents may also be as a future source of energy.

Here, repeatedly stressed that the geological structure and geological structure of celestial bodies, the Earth, Moon, Mars, or that this human existence and development of biological life forms is very important, especially in a series of data Martian geological structure geological structure is directly related to human landing Mars and the successful transformation of Mars or not. for example, water, liquid water, water, oxygen, synthesis, must not be taken lightly.

Mars landing 10 Technology

 

Aerospace Science and space science and technology major innovation of the most critical of sophisticated technology R & D project

  

[

"1" rocket propulsion technology ion fusion nuclear pulse propulsion rocket powered high-speed heavy rocket technology, space nuclear reactors spacecraft] brought big problems reflected in the nuclear reaction, nuclear radiation on spacecraft launch, control, brakes and other impact.

In particular, for the future of nuclear power spacecraft, the need to solve the nuclear reactor design, manufacture, control, cooling, radiation shielding, exhaust pollution, high thermoelectric conversion efficiency and a series of technical problems.

In particular, nuclear reactors produce radiation on astronauts' health will pose a great threat, which requires the spacecraft to be nuclear radiation shielding to ensure astronaut and ship the goods from radiation and heat from the reactor influence, but this will greatly increase the weight of the detector.

Space nuclear process applications, nuclear reaction decay is not a problem, but in a vacuum, ultra-low temperature environment, the nuclear reaction materials, energy transport materials have very high demands.

Space facing the reality of a nuclear reactor cooling cooling problems. To prevent problems with the reactor, "Washington" aircraft carrier to take four heavy protective measures for the radiation enclosed in the warship. These four measures are: the fuel itself, fuel storage pressure vessel, reactor shell and the hull. US Navy fuel all metal fuel, designed to take the impact resistance of the war, does not release fission product can withstand more than 50 times the gravity of the impact load; product of nuclear fission reactor fuel will never enter loop cooling water. The third layer of protection is specially designed and manufactured the reactor shell. The fourth layer is a very strong anti-impact combat ship, the reactor is arranged in the center of the ship, very safe. Engage in a reactor can only be loaded up to the aircraft, so as to drive the motor, and then drive the propeller. That is the core advantage of the heat generated by the heated gas flow, high temperature high pressure gas discharge backward, thereby generating thrust.

  

.

  

After installation AMPS1000 type nuclear power plant, a nuclear fuel assembly: He is a core member of the nuclear fuel chain reaction. Usually made into uranium dioxide, of which only a few percent uranium-235, and most of it is not directly involved in the nuclear fission of uranium 238. The uranium dioxide sintered into cylindrical pieces, into a stainless steel or a zirconium alloy do metal tubes called fuel rods or the original, then the number of fuel rods loaded metal cylinder in an orderly composition of the fuel assembly, and finally put a lot of vertical distribution of fuel assemblies in the reactor.

 

Nuclear reactor pressure vessel is a housing for containing nuclear fuel and reactor internals, for producing high-quality high-strength steel is made to withstand the pressure of dozens MPa. Import and export of the coolant in the pressure vessel.

 

The top of the pressure vessel closure, and can be used to accommodate the fixed control rod drive mechanism, pressure vessel head has a semi-circular, flat-topped.

 

Roof bolt: used to connect the locking pressure vessel head, so that the cylinder to form a completely sealed container.

  

Neutron Source: Plug in nuclear reactors can provide sufficient neutron, nuclear fuel ignition, to start to enhance the role of nuclear reactors and nuclear power. Neutron source generally composed of radium, polonium, beryllium, antimony production. Neutron source and neutron fission reactors are fast neutron, can not cause fission of uranium 235, in order to slow down, we need to moderator ---- full of pure water in a nuclear reactor. Aircraft carriers, submarines use nuclear reactor control has proven more successful.

 

Rod: has a strong ability to absorb neutrons, driven by the control rod drive mechanism, can move up and down in a nuclear reactor control rods within the nuclear fuel used to start, shut down the nuclear reactor, and maintain, regulate reactor power. Hafnium control rods in general, silver, indium, cadmium and other metals production.

 

Control rod drive mechanism: He is the executive body of nuclear reactors operating system and security protection systems, in strict accordance with requirements of the system or its operator control rod drives do move up and down in a nuclear reactor, nuclear reactor for power control. In a crisis situation, you also can quickly control rods fully inserted into the reactor in order to achieve the purpose of the emergency shutdown

 

Upper and lower support plate: used to secure the fuel assembly. High temperature and pressure inside the reactor is filled with pure water (so called pressurized water reactors), on the one hand he was passing through a nuclear reactor core, cooling the nuclear fuel, to act as a coolant, on the other hand it accumulates in the pressure vessel in play moderated neutrons role, acting as moderator.

  

Water quality monitoring sampling system:

Adding chemical system: under normal circumstances, for adding hydrazine, hydrogen, pH control agents to the primary coolant system, the main purpose is to remove and reduce coolant oxygen, high oxygen water suppression equipment wall corrosion (usually at a high temperature oxygen with hydrogen, especially at low temperatures during startup of a nuclear reactor with added hydrazine oxygen); when the nuclear reactor control rods stuck for some reason can not shutdown time by the the system can inject the nuclear reactor neutron absorber (such as boric acid solution), emergency shutdown, in order to ensure the safety of nuclear submarines.

 

Water system: a loop inside the water will be reduced at work, such as water sampling and analysis, equipment leaks, because the shutdown process cooling water and reduction of thermal expansion and contraction.

 

Equipment cooling water system:

Pressure safety systems: pressure reactor primary coolant system may change rapidly for some reason, the need for effective control. And in severe burn nuclear fuel rods, resulting in a core melt accident, it is necessary to promptly increase the pressure. Turn the regulator measures the electric, heating and cooling water. If necessary, also temporary startup booster pump.

 

Residual Heat Removal System: reactor scram may be due to an accident, such as when the primary coolant system of the steam generator heat exchanger tube is damaged, it must be urgently closed reactors.

 

Safety Injection System: The main components of this system is the high-pressure injection pump.

 

Radioactive waste treatment systems:

 

Decontamination Systems: for the removal of radioactive deposits equipment, valves, pipes and accessories, and other surfaces.

 

Europe, the United States and Russia and other countries related to aircraft carriers, submarines, icebreakers, nuclear-powered research aircraft, there are lots of achievements use of nuclear energy, it is worth analysis. However, nuclear reactor technology, rocket ships and the former are very different, therefore, requires special attention and innovative research. Must adopt a new new design techniques, otherwise, fall into the stereotype, it will avail, nothing even cause harm Aerospace.

Fangruida: human landing on Mars 10 cutting-edge technology

[Fangruida- human landing on Mars 10 innovative and sophisticated technologies]

Aerospace Science and space science and technology major innovation of the most critical of sophisticated technology R & D project

-------------------------------------------------- -------------

Aerospace Science Space Science and Technology on behalf of the world's most cutting-edge leader in high technology, materials, mechatronics, information and communication, energy, biomedical, marine, aviation aerospace, microelectronics, computer, automation, intelligent biochips, use of nuclear energy, light mechanical and electrical integration, astrophysics, celestial chemistry, astrophysics and so a series of geological science and technology. Especially after the moon landing, the further development of mankind to Mars and other planets into the powerful offensive, the world's major powers eager to Daxian hand of God, increase investment, vigorously develop new sophisticated technology projects for space to space. Satellite, space station, the new spacecraft, the new space suits, the new radiation protection materials, intelligent materials, new manufacturing technology, communications technology, computer technology, detector technology, rover, rover technology, biomedical technology, and so one after another, is expected to greater breakthroughs and leaps. For example, rocket technology, spacecraft design, large power spacecraft, spacesuits design improvements, radiation multifunctional composite materials, life health care technology and space medicine, prevention against microgravity microgravity applicable drugs, tracking control technology, landing and return technology. Mars lander and returned safely to Earth as a top priority. Secondly, Mars, the Moon base and the use of transforming Mars, the Moon and other development will follow. Whether the former or the latter, are the modern aerospace science, space science basic research, applied basic research and applied research in the major cutting-edge technology. These major cutting-edge technology research and innovation, not only for human landing on Mars and the safe return of great significance, but for the entire space science, impact immeasurable universe sciences, earth sciences and human life. Here the most critical of the most important research projects of several sophisticated technology research and development as well as its core technology brief. Limit non-scientific techniques include non-technical limits of technology, the key lies in technology research and development of technology maturity, advanced technology, innovative, practical, reliable, practical application, business value and investment costs, and not simply like the idea mature technology achievements, difficult to put into things. This is the high-tech research and development, testing, prototype, test application testing, until the outcome of industrialization. Especially in aerospace technology, advanced, novelty, practicality, reliability, economy, maturity, commercial value and so on. For technical and research purely science fiction and the like may be irrelevant depth, but not as aerospace engineering and technology practice. Otherwise, Mars will become a dream fantasy, and even into settling crashed out of danger.

Regardless of the moon or Mars, many technical difficulties, especially a human landing on Mars and return safely to Earth, technical difficulties mainly in the following aspects. (Transformation of Mars and the Moon and other planets and detect other livable technology more complex and difficult, at this stage it is difficult to achieve and therefore not discussed in detail in this study). In fact, Mars will be the safe return of a full set of technology, space science, aerospace crucial scientific research development, its significance is not confined to Mars simply a return to scientific value, great commercial value, can not be measure.

1. Powered rocket, the spacecraft overall structural design not be too complex large, otherwise, the safety factor to reduce the risk of failure accidents. Fusion rocket engine main problem to be solved is the high-temperature materials and fuel ignition chamber (reaction chamber temperatures of up to tens of millions of supreme billion degrees), fissile class rocket engine whose essence is the miniaturization of nuclear reactors, and placed on the rocket. Nuclear rocket engine fuel as an energy source, with liquid hydrogen, liquid helium, liquid ammonia working fluid. Nuclear rocket engine mounted in the thrust chamber of the reactor, cooling nozzle, the working fluid delivery and control systems and other components. This engine due to nuclear radiation protection, exhaust pollution, reactor control and efficient heat exchanger design and other issues unresolved. Electrothermal rocket engine utilizing heat energy (resistance heating or electric arc heating) working medium (hydrogen, amines, hydrazine ), vaporized; nozzle expansion accelerated after discharged from the spout to generate thrust. Static rocket engine working fluid (mercury, cesium, hydrogen, etc.) from the tank enter the ionization chamber is formed thrust ionized into a plasma jet. Electric rocket engines with a high specific impulse (700-2500 sec), extremely long life (can be repeated thousands of times a starter, a total of up to thousands of hours of work). But the thrust of less than 100N. This engine is only available for spacecraft attitude control, station-keeping and the like. One nuclear - power rocket design is as follows: Firstly, the reactor heats water to make it into steam, and then the high-speed steam ejected, push the rocket. Nuclear rocket using hydrogen as working substance may be a better solution, it is one of the most commonly used liquid hydrogen rocket fuel rocket carrying liquid hydrogen virtually no technical difficulties. Heating hydrogen nuclear reactor, as long as it eventually reaches or exceeds current jet velocity hydrogen rocket engine jet speed, the same weight of the rocket will be able to work longer, it can accelerate the Rockets faster. Here there are only two problems: First, the final weight includes the weight of the rocket in nuclear reactors, so it must be as light as possible. Ultra-small nuclear reactor has been able to achieve. Furthermore, if used in outer space, we can not consider the problem of radioactive residues, simply to just one proton hydrogen nuclei are less likely to produce induced radioactivity, thus shielding layer can be made thinner, injected hydrogen gas can flow directly through the reactor core, it is not easy to solve, and that is how to get back at high speed heated gas is ejected.

Rocket engine with a nuclear fission reactor, based on the heating liquid hydrogen propellant, rather than igniting flammable propellant

High-speed heavy rocket is a major cutting-edge technology. After all, space flight and aircraft carriers, submarines, nuclear reactors differ greatly from the one hand, the use of traditional fuels, on the one hand can be nuclear reactor technology. From the control, for security reasons, the use of nuclear power rocket technology, safe and reliable overriding indicators. Nuclear atomic energy in line with the norms and rules of outer space. For the immature fetal abdominal hatchery technology, and resolutely reject use. This is the most significant development of nuclear-powered rocket principle.

Nuclear-powered spaceship for Use of nuclear power are three kinds:

The first method: no water or air space such media can not be used propeller must use jet approach. Reactor nuclear fission or fusion to produce a lot of heat, we will propellant (such as liquid hydrogen) injection, the rapid expansion of the propellant will be heated and then discharged from the engine speed tail thrust. This method is most readily available.

The second method: nuclear reactor will have a lot of fast-moving ions, these energetic particles moving very fast, so you can use a magnetic field to control their ejection direction. This principle ion rocket similar to the tail of the rocket ejected from the high-speed mobile ions, so that the recoil movement of a rocket. The advantage of this approach is to promote the unusually large ratio, without carrying any medium, continued strong. Ion engine, which is commonly referred to as "electric rocket", the principle is not complicated, the propellant is ionized particles,

Plasma Engine

Electromagnetic acceleration, high-speed spray. From the development trend, the US research scope covers almost all types of electric thrusters, but mainly to the development of ion engines, NASA in which to play the most active intake technology and preparedness plans. "

The third method: the use of nuclear explosions. It is a bold and crazy way, no longer is the use of a controlled nuclear reaction, but to use nuclear explosions to drive the ship, this is not an engine, and it is called a nuclear pulse rocket. This spacecraft will carry a lot of low-yield atomic bombs out one behind, and then detonated, followed by a spacecraft propulsion installation disk, absorbing the blast pushing the spacecraft forward. This was in 1955 to Orion (Project Orion) name of the project, originally planned to bring two thousand atomic bombs, Orion later fetal nuclear thermal rocket. Its principle is mounted on a small rocket reactor, the reactor utilizing thermal energy generated by the propellant is heated to a high temperature, high pressure and high temperature of the propellant from the high-speed spray nozzle, a tremendous impetus.

Common nuclear fission technologies, including nuclear pulse rocket engines, nuclear rockets, nuclear thermal rocket and nuclear stamping rockets to nuclear thermal rocket, for example, the size of its land-based nuclear power plant reactor structure than the much smaller, more uranium-235 purity requirements high, reaching more than 90%, at the request of the high specific impulse engine core temperature will reach about 3000K, require excellent high temperature properties of materials.

Research and test new IT technologies and new products and new technology and new materials, new equipment, things are difficult, design is the most important part, especially in the overall design, technical solutions, technical route, technical process, technical and economic particularly significant. The overall design is defective, technology there are loopholes in the program, will be a major technical route deviation, but also directly related to the success of research trials. so, any time, under any circumstances, a good grasp of the overall control of design, technical design, is essential. otherwise, a done deal, it is difficult save. aerospace technology research and product development is true.

3, high-performance nuclear rocket

Nuclear rocket nuclear fission and fusion energy can rocket rocket two categories. Nuclear fission and fusion produce heat, radiation and shock waves and other large amounts of energy, but here they are contemplated for use as a thermal energy rocket.

Uranium and other heavy elements, under certain conditions, will split their nuclei, called nuclear fission reaction. The atomic bomb is the result of nuclear fission reactions. Nuclear fission reaction to release energy, is a million times more chemical rocket propellant combustion energy. Therefore, nuclear fission energy is a high-performance rocket rockets. Since it requires much less propellant than chemical rockets can, so to its own weight is much lighter than chemical rockets energy. For the same quality of the rocket, the rocket payload of nuclear fission energy is much greater than the chemical energy of the rocket. Just nuclear fission energy rocket is still in the works. 

Use of nuclear fission energy as the energy of the rocket, called the atomic rockets. It is to make hydrogen or other inert gas working fluid through the reactor, the hydrogen after the heating temperature quickly rose to 2000 ℃, and then into the nozzle, high-speed spray to produce thrust. 

A vision plan is to use liquid hydrogen working fluid, in operation, the liquid hydrogen tank in the liquid hydrogen pump is withdrawn through the catheter and the engine cooling jacket and liquid hydrogen into hydrogen gas, hydrogen gas turbine-driven, locally expansion. Then by nuclear fission reactors, nuclear fission reactions absorb heat released, a sharp rise in temperature, and finally into the nozzle, the rapid expansion of high-speed spray. Calculations show that the amount of atomic payload rockets, rocket high chemical energy than 5-8 times.

Hydrogen and other light elements, under certain conditions, their nuclei convergent synthesis of new heavy nuclei, and release a lot of energy, called nuclear fusion reaction, also called thermonuclear reaction. 

Using energy generated by the fusion reaction for energy rocket, called fusion energy rocket or nuclear thermal rockets. But it is also not only take advantage of controlled nuclear fusion reaction to manufacture hydrogen bombs, rockets and controlled nuclear fusion reaction needs still studying it.

Of course there are various research and development of rocket technology and technical solutions to try.

It is envisaged that the rocket deuterium, an isotope of hydrogen with deuterium nuclear fusion reaction of helium nuclei, protons and neutrons, and release huge amounts of energy, just polymerized ionized helium to temperatures up to 100 million degrees the plasma, and then nozzle expansion, high-speed ejection, the exhaust speed of up to 15,000 km / sec, atomic energy is 1800 times the rocket, the rocket is the chemical energy of 3700 times.

Nuclear rocket engine fuel as an energy source, with liquid hydrogen, liquid helium, liquid ammonia working fluid. Nuclear rocket engine mounted in the thrust chamber of the reactor, cooling nozzle, the working fluid delivery and control systems and other components. In a nuclear reactor, nuclear energy into heat to heat the working fluid, the working fluid is heated after expansion nozzle to accelerate to the speed of 6500 ~ 11,000 m / sec from the discharge orifice to produce thrust. Nuclear rocket engine specific impulse (250 to 1000 seconds) long life, but the technology is complex, apply only to long-term spacecraft. This engine due to nuclear radiation protection, exhaust pollution, reactor control and efficient heat exchanger design and other issues not resolved, is still in the midst of trials. Nuclear rocket technology is cutting-edge aerospace science technology, centralized many professional and technical sciences and aerospace, nuclear physics, nuclear chemistry, materials science, the long term future ___-- wide width. The United States, Russia and Europe, China, India, Japan, Britain, Brazil and other countries in this regard have studies, in particular the United States and Russia led the way, impressive. Of course, at this stage of nuclear rocket technology, technology development there are still many difficulties. Fully formed, still to be. But humanity marching to the universe, nuclear reactor applications is essential.

3. Air. Perhaps the oxygen needed to rely on oxidation-reduction reaction of hydrogen and ilmenite production of water, followed by water electrolysis to generate oxygen. Mars oxygen necessary for survival but also from the decomposition of water, electrolytically separating water molecules of oxygen and hydrogen, this oxygen equipment has been successfully used in the International Space Station. Oxygen is released into the air to sustain life, the hydrogen system into the water system.

4. The issue of food waste recycling. At present, the International Space Station on the use of dehumidifiers, sucked moisture in the air to be purified, and then changed back to drinkable water. The astronauts' urine and sweat recycling. 5. water. The spacecraft and the space station on purification system also makes urine and other liquids can be purified utilization. 6. microgravity. In microgravity or weightlessness long-term space travel, if protective measures shall not be treated, the astronauts will be muscle atrophy, bone softening health. 7. contact. 8. Insulation, 9 energy. Any space exploration are inseparable from the energy battery is a new super hybrid energy storage device, the asymmetric lead-acid batteries and supercapacitors in the same compound within the system - and the so-called inside, no additional separate electronic control unit, this is an optimal combination. The traditional lead-acid battery PbO2 monomer is a positive electrode plate and a negative electrode plate spongy Pb composition, not a super cell. : Silicon solar cells, multi-compound thin film solar cells, multi-layer polymer-modified electrode solar cells, nano-crystalline solar cells, batteries and super class. For example, the solar aircraft .10. To protect the health and life safety and security systems. Lysophosphatidic acid LPA is a growth factor-like lipid mediators, the researchers found that this substance can on apoptosis after radiation injury and animal cells was inhibited. Stable lysophosphatidic acid analogs having the hematopoietic system and gastrointestinal tract caused by acute radiation sickness protection, knockout experiments show that lysophosphatidic acid receptors is an important foundation for the protection of radiation injury. In addition to work under high pressure, the astronauts face a number of health threats, including motion sickness, bacterial infections, blindness space, as well as psychological problems, including toxic dust. In the weightless environment of space, the astronaut's body will be like in preadolescents, as the emergence of various changes.

Plantar molt

After the environment to adapt to zero gravity, the astronaut's body will be some strange changes. Weightlessness cause fluid flow around the main flow torso and head, causing the astronauts facial swelling and inflammation, such as nasal congestion. During long-term stay in space

Bone and muscle loss

Most people weightlessness caused by the impact may be known bone and muscle degeneration. In addition, the calcium bones become very fragile and prone to fracture, which is why some of the astronauts after landing need on a stretcher.

Space Blindness

Space Blindness refers astronaut decreased vision.

Solar storms and radiation is one of the biggest challenges facing the long-term space flight. Since losing the protection of Earth's magnetic field, astronauts suffer far more than normal levels of radiation. The cumulative amount of radiation exposure in low earth orbit them exceeded by workers close to nuclear reactors, thereby increasing the risk of cancer.

Prolonged space flight can cause a series of psychological problems, including depression or mood swings, vulnerability, anxiety and fear, as well as other sequelae. We are familiar with the biology of the Earth, the Earth biochemistry, biophysics, after all, the Earth is very different astrophysics, celestial chemistry, biophysics and astrophysics, biochemistry and other celestial bodies. Therefore, you must be familiar with and adapt to these differences and changes.

Osteoporosis and its complications ranked first in the space of disease risk.

Long-term health risks associated with flying Topics

The degree of influence long-term biological effects of radiation in human flight can withstand the radiation and the maximum limit of accumulated radiation on physiology, pathology and genetics.

However, space technology itself is integrated with the use of the most advanced technology, its challenging technical reserves and periodic demanding

With the continuous development of science and technology, space agencies plan a manned landing on the moon and Mars, space exploration emergency medicine current concern.

Space sickness

In the weightless environment of space, in the weightless environment of space, surgery may be extremely difficult and risky.

Robot surgeons

Space disease in three days after entering the space started to ease, although individual astronauts might subsequently relapse. January 2015 NASA declared working on a fast, anti-nausea and nasal sprays. In addition, due to the zero-gravity environment, and anti-nausea drugs can only be administered by injection or transdermal patches manner.

Manned spaceflight in the 21st century is the era of interplanetary flight, aerospace medicine is closely watched era is the era of China's manned space flourish. Only the central issue, and grasp the opportunity to open up a new world of human survival and development.

Various emergency contingency measures in special circumstances. Invisible accident risk prevention. Enhancing drugs and other screening methods immunity aerospace medicine and tissue engineering a microgravity environment. Drug mixture of APS, ginseng polysaccharides, Ganoderma lucidum polysaccharides, polysaccharides and Lentinan, from other compounds. Drug development space syndrome drug, chemical structure modification will be an important part.

These issues are very sensitive, cutting-edge technology is a major difficulty landing on Mars. Countries in the world, especially the world's major space powers in the country strategies and technical research, the results of all kinds continue to emerge. United States, Russia, China, Europe, India, Japan and other countries is different. United States, Russia extraordinary strength. Many patented technology and health, and most belong to the top-secret technology. Especially in aerospace engineering and technological achievements is different from the general scientific literature, practical, commercial, industrial great, especially the performance of patents, know-how, technical drawings, engineering design and other aspects. Present Mars and return safely to Earth, the first manned, significance, everything is hard in the beginning, especially the first person to land on Mars This Mars for Human Sciences Research Mars, the moon, the earth, the solar system and the universe, life and other significant. Its far greater than the value of direct investments and business interests.

In addition, it is the development of new materials, suitable for deep space operations universe, life, and other detection, wider field.

Many aerospace materials, continuous research and development of materials are key areas of aerospace development, including material rocket, the spacecraft materials, the suit materials, radiation materials, materials and equipment, instruments, materials and so on biochemistry.

W Fiber Reinforced with nickel-based, iron-based alloys as well as SiC, TiB2, Si3N4 and BN particle reinforced metal matrix composites

High temperature service conditions require the development of ceramic and carbon-based composite materials, etc., not in this eleven Cheung said.

Fuel storage

In order to survive in space, people need many things: food, oxygen, shelter, and, perhaps most importantly, fuel. The initial quality Mars mission somewhere around 80 percent of the space launch humans will be propellant. The fuel amount of storage space is very difficult.

This difference in low Earth orbit cause liquid hydrogen and liquid oxygen - rocket fuel - vaporization.

Hydrogen is particularly likely to leak out, resulting in a loss of about 4% per month.

When you want to get people to Mars speed to minimize exposure to weightlessness and space radiation hazards

Mars

Landings on the Martian surface, they realized that they reached the limit. The rapid expansion of the thin Martian atmosphere can not be very large parachute, such as those that will need to be large enough to slow down, carry human spacecraft.

Therefore, the parachute strong mass ratio, high temperature resistance, Bing shot performance and other aspects of textile materials used have special requirements, in order to make a parachute can be used in rockets, missiles, Yu arrows spacecraft and other spacecraft recovery, it is necessary to improve the canopy heat resistance, a high melting point polymeric fiber fabric used, the metal fabric, ceramic fiber fabrics, and other devices.

Super rigid parachute to help slow the landing vehicle.

Spacecraft entered the Martian atmosphere at 24,000 km / h. Even after slowing parachute or inflatable, it will be very

Once we have the protection of the Earth magnetic field, the solar radiation will accumulate in the body, a huge explosion threw the spacecraft may potentially lethal doses of radiation astronauts.

In addition to radiation, the biggest challenge is manned trip to Mars microgravity, as previously described.

The moon is sterile. Mars is another case entirely.

Arid Martian environment to create a super-tiny dust particles flying around the Earth for billions of years.

Apollo moon dust encountered. Ultra-sharp and abrasive lunar dust was named something that can clog the basic functions of mechanical damage. High chloride salt, which can cause thyroid problems in people.

Mars geological structure and geological structure of the moon, water on Mars geology, geology of the Moon is very important, because he, like the Earth's geology is related to many important issues. Water, the first element of life, air, temperature, and complex geological formations are geological structure. Cosmic geology research methods, mainly through a variety of detection equipment equipped with a space probe, celestial observations of atmospheric composition, composition and distribution of temperature, pressure, wind speed, vertical structure, composition of the solar wind, the water, the surface topography and Zoning, topsoil the composition and characteristics of the component surface of the rock, type and distribution, stratigraphic sequence, structural system and the internal shell structure.

Mars internal situation only rely on its surface condition of large amounts of data and related information inferred. It is generally believed that the core radius of 1700 km of high-density material composition; outsourcing a layer of lava, it is denser than the Earth's mantle some; outermost layer is a thin crust. Compared to other terrestrial planets, the lower the density of Mars, which indicates that the Martian core of iron (magnesium and iron sulfide) with may contain more sulfur. Like Mercury and the Moon, Mars and lack active plate movement; there is no indication that the crust of Mars occurred can cause translational events like the Earth like so many of folded mountains. Since there is no lateral movement in the earth's crust under the giant hot zone relative to the ground in a stationary state. Slight stress coupled with the ground, resulting in Tharis bumps and huge volcano. For the geological structure of Mars is very important, which is why repeated explorations and studies of Martian geological reasons.

Canyon of Mars there are two categories: outflow channels (outflow channel) and tree valley (valley network). The former is very large, it can be 100 km wide, over 2000 km long, streamlined, mainly in the younger Northern Hemisphere, such as the plain around Tyre Chris Canyon and Canyon jam.

In addition, the volcanic activity sometimes lava formation lava channels (lava channel); crustal stress generated by fissures, faults, forming numerous parallel extending grooves (fossa), such as around the huge Tharsis volcanic plateau radially distributed numerous grooves, which can again lead to volcanic activity.

Presumably, Mars has an iron as the main component of the nucleus, and contains sulfur, magnesium and other light elements, the nuclear share of Mars, the Earth should be relatively small. The outer core is covered with a thick layer of magnesium-rich silicate mantle, the surface of rocky crust. The density of Earth-like planets Mars is the lowest, only 3.93g / cc.

The average density of the Moon is 3.3464 g / cc, the solar system satellites second highest (after Aiou). However, there are few clues mean lunar core is small, only about 350 km radius or less [2]. The core of the moon is only about 20% the size of the moon, the moon's interior has a solid, iron-rich core diameter of about 240 kilometers (150 miles); in addition there is a liquid core, mainly composed of iron outer core, about 330 km in diameter (205 miles), and for the first time compared with the core of the Earth, considered as the earth's outer core, like sulfur and oxygen may have lighter elements [4].

Chemical elements on the lunar surface constituted in accordance with its abundance as follows: oxygen (O), silicon (Si), iron (Fe), magnesium (Mg), calcium (Ca), aluminum (Al), manganese (Mn), titanium ( Ti). The most abundant is oxygen, silicon and iron. The oxygen content is estimated to be 42% (by weight).

Mars landing 10 Technology

Aerospace Science and space science and technology major innovation of the most critical of sophisticated technology R & D project

[

"1" rocket propulsion technology ion fusion nuclear pulse propulsion rocket powered high-speed heavy rocket technology, space nuclear reactors spacecraft] brought big problems reflected in the nuclear reaction, nuclear radiation on spacecraft launch, control, brakes and other impact.

In particular, for the future of nuclear power spacecraft, the need to solve the nuclear reactor design, manufacture, control, cooling, radiation shielding, exhaust pollution, high thermoelectric conversion efficiency and a series of technical problems.

In particular, nuclear reactors produce radiation on astronauts' health will pose a great threat, which requires the spacecraft to be nuclear radiation shielding to ensure astronaut and ship the goods from radiation and heat from the reactor influence, but this will greatly increase the weight of the detector.

Space nuclear process applications, nuclear reaction decay is not a problem, but in a vacuum, ultra-low temperature environment, the nuclear reaction materials, energy transport materials have very high demands.

Space facing the reality of a nuclear reactor cooling cooling problems. To prevent problems with the reactor, "Washington" aircraft carrier to take four heavy protective measures for the radiation enclosed in the warship. These four measures are: the fuel itself, fuel storage pressure vessel, reactor shell and the hull. US Navy fuel all metal fuel, designed to take the impact resistance of the war, does not release fission product can withstand more than 50 times the gravity of the impact load; product of nuclear fission reactor fuel will never enter loop cooling water. The third layer of protection is specially designed and manufactured the reactor shell. The fourth layer is a very strong anti-impact combat ship, the reactor is arranged in the center of the ship, very safe. Engage in a reactor can only be loaded up to the aircraft, so as to drive the motor, and then drive the propeller. That is the core advantage of the heat generated by the heated gas flow, high temperature high pressure gas discharge backward, thereby generating thrust.

.

After installation AMPS1000 type nuclear power plant, a nuclear fuel assembly: He is a core member of the nuclear fuel chain reaction. Usually made into uranium dioxide, of which only a few percent uranium-235, and most of it is not directly involved in the nuclear fission of uranium 238. The uranium dioxide sintered into cylindrical pieces, into a stainless steel or a zirconium alloy do metal tubes called fuel rods or the original, then the number of fuel rods loaded metal cylinder in an orderly composition of the fuel assembly, and finally put a lot of vertical distribution of fuel assemblies in the reactor.

Nuclear reactor pressure vessel is a housing for containing nuclear fuel and reactor internals, for producing high-quality high-strength steel is made to withstand the pressure of dozens MPa. Import and export of the coolant in the pressure vessel.

The top of the pressure vessel closure, and can be used to accommodate the fixed control rod drive mechanism, pressure vessel head has a semi-circular, flat-topped.

Roof bolt: used to connect the locking pressure vessel head, so that the cylinder to form a completely sealed container.

Neutron Source: Plug in nuclear reactors can provide sufficient neutron, nuclear fuel ignition, to start to enhance the role of nuclear reactors and nuclear power. Neutron source generally composed of radium, polonium, beryllium, antimony production. Neutron source and neutron fission reactors are fast neutron, can not cause fission of uranium 235, in order to slow down, we need to moderator ---- full of pure water in a nuclear reactor. Aircraft carriers, submarines use nuclear reactor control has proven more successful.

Rod: has a strong ability to absorb neutrons, driven by the control rod drive mechanism, can move up and down in a nuclear reactor control rods within the nuclear fuel used to start, shut down the nuclear reactor, and maintain, regulate reactor power. Hafnium control rods in general, silver, indium, cadmium and other metals production.

Control rod drive mechanism: He is the executive body of nuclear reactors operating system and security protection systems, in strict accordance with requirements of the system or its operator control rod drives do move up and down in a nuclear reactor, nuclear reactor for power control. In a crisis situation, you also can quickly control rods fully inserted into the reactor in order to achieve the purpose of the emergency shutdown

Upper and lower support plate: used to secure the fuel assembly. High temperature and pressure inside the reactor is filled with pure water (so called pressurized water reactors), on the one hand he was passing through a nuclear reactor core, cooling the nuclear fuel, to act as a coolant, on the other hand it accumulates in the pressure vessel in play moderated neutrons role, acting as moderator.

Water quality monitoring sampling system:

Adding chemical system: under normal circumstances, for adding hydrazine, hydrogen, pH control agents to the primary coolant system, the main purpose is to remove and reduce coolant oxygen, high oxygen water suppression equipment wall corrosion (usually at a high temperature oxygen with hydrogen, especially at low temperatures during startup of a nuclear reactor with added hydrazine oxygen); when the nuclear reactor control rods stuck for some reason can not shutdown time by the the system can inject the nuclear reactor neutron absorber (such as boric acid solution), emergency shutdown, in order to ensure the safety of nuclear submarines.

Water system: a loop inside the water will be reduced at work, such as water sampling and analysis, equipment leaks, because the shutdown process cooling water and reduction of thermal expansion and contraction.

Equipment cooling water system:

Pressure safety systems: pressure reactor primary coolant system may change rapidly for some reason, the need for effective control. And in severe burn nuclear fuel rods, resulting in a core melt accident, it is necessary to promptly increase the pressure. Turn the regulator measures the electric, heating and cooling water. If necessary, also temporary startup booster pump.

Residual Heat Removal System: reactor scram may be due to an accident, such as when the primary coolant system of the steam generator heat exchanger tube is damaged, it must be urgently closed reactors.

Safety Injection System: The main components of this system is the high-pressure injection pump.

Radioactive waste treatment systems:

Decontamination Systems: for the removal of radioactive deposits equipment, valves, pipes and accessories, and other surfaces.

Europe, the United States and Russia and other countries related to aircraft carriers, submarines, icebreakers, nuclear-powered research aircraft, there are lots of achievements use of nuclear energy, it is worth analysis. However, nuclear reactor technology, rocket ships and the former are very different, therefore, requires special attention and innovative research. Must adopt a new new design techniques, otherwise, fall into the stereotype, it will avail, nothing even cause harm Aerospace.

Casey died last night at 7:05 p.m. She died within 17 hours after having surgery for a twisted stomach (also known as bloat or Gastric Dilatation and Volvulus).

 

This came completely out of the blue and it was so sudden which makes this all the more difficult and painful to deal with.

 

If you go here: www.marvistavet.com/html/body_bloat.html this explains what the problem is.

 

If you have a larger breed dog (which are the ones that tend to be affected), PLEASE go to website and read this so you know what the symptoms are and what they look like.

 

According to the site, there are many injuries and physical disorders which represent life-threatening emergencies. There is only one condition so drastic that it over shadows them all in terms of rapidity of consequences and effort in emergency treatment...and this is the one.

 

Basically what happened to Casey was that she had two seizures last Tuesday (February 5th) during the night. Never had them before. She had another one on Monday, February 11th. This was was more intense and the duration was much longer.

 

The vet said to bring her in Tuesday, February 12th to have blood and urine work done to see if there's an underlying reason for the seizures. So, I brought her in for the tests in the morning. Picked her up in the afternoon.

 

Fed her a normal dinner when she got home since I figured she be hungry after a long day at the vet. Montague (the golden retreiver) and Casey had dinner.

 

After her dinner, I tried giving Casey her first pill to control seizures. Put it in a peach. She didn't want it (normally she would have eaten it). Put it in a piece of cheese. She struggled to eat it. Thought that was unusual.

 

Then I noticed she was starting to pace, drink water, wanted to outside. Repeatedly. Wouldn't sit down or rest. Felt her side and her heart was beating VERY rapidly. This went on for a little while.

 

Called the vet. He thought, perhaps, it could have been overstimulation at the vet...too many things going on, new noises, etc. Suggested letting her go outside on walks since that seems to calm her down a bit.

 

Bundled up and took her for a walk. She walked very slowly through the backyard and then out into the pasture. Stopped a couple of times. Paws were cold. Warmed them up for her.

 

Then she didn't want to go any further once she got to the corner of the pasture. Tried to encourage her. Ended up picking her up (a good 65+ pounds) and carrying her back to the house. This was VERY strange because normally she does not let me carry her...especially on walks (not that I ever tried to do that..but she didn't like to be picked up even to help her get into the car).

 

Back inside, I looked at her and she seemed large right around the lower ribs and immediately below that. She kept pacing, breathing heavily, wouldn't sit down. I thought she may know a seizure is coming. Turned the lights out. Had the girls go upstairs so it was quiet. Finally she found a spot and rested for a while.

 

Read bedtime stories to the girls. Came back downstairs to check on Casey. Now she was sitting on the couch where I like to sit. Hadn't seen her there for AGES. Okay. Something strange IS going on.

 

Sat down next to her and put my hand under her chin and lifted it up. Looked into her eyes and just KNEW something wasn't right. Called the vet. Described what was going on. Told me to get there right away.

 

At the vet, an ultrasound was done. Looked fine. For some reason, the x-ray machine didn't work (which would have immediately showed a twisted stomach)...suggested having her walk outside to observe her.

 

Outside, she didn't want to go to the bathroom. Just walked slowly away. Didn't respond to my voice. "Is this normal behavior for Casey?" he asked. "No, not at all." Looked at her and her back seemed to be arching a bit and she was still rather large.

 

Ended up heading down to the emergency animal hospital about 50 minutes away (the closest one) while the vet called in the information and prepared them for Casey's arrival.

 

Once there, they immediately x-rayed her. Her stomach was twisted. Two options: surgery or euthanasia. Chose surgery. Wanted her to have a chance. There were no guarantees since some dogs do well after surgery while others don't survive surgery or the critical couple days following surgery. Still...go ahead and try.

 

Surgery was difficult and there were complications. She was bleeding a lot and had to have a blood transfusion. Blood pressure was VERY low. Spleen was removed since it was necrotic. A growth was on the spleen (not sure if it was cancerous or not).

 

She spent the remainder of the night there on IVs and monitors. She was released at 7:30 so I could transport her to the University of Minnesota's Veterinary Hospital.

 

They literally ran her on a gurney into the emergency room. Within a 15-20 minute car ride there, her heart rate elevated substantially and blood pressure dropped dangerously low. She was bleeding from the incision site.

 

She was hooked up to multiple IVs and monitors. From 8-11 a.m., I stayed there. She was unstable and in critical condition throughout this time period. Multiple problems. However, she was heavily sedated and had lots of pain medicine so she wouldn't feel any pain. This was SO critical for me to know that she wasn't feeling any pain.

 

I visited her back in the emergency room about every 20 minutes. During one of the visits when they had placed her on oxygen and she was still heavily sedated and non-responsive, I leaned down and said, "Hi Casey. It's Ann. What a good girl you are..." and she lifted her head off the table and looked at me. (Later when talking with one of Casey's regular vets at Osceola, she said that it is amazing what animals will do to let their owners know they can hear them despite the pain or compromised situation they are in.)

 

By 11, Casey had stabalized, but was still critical. They were transferring her to an ICU unit (rather than the emergency room). At that point the team that was working with her suggested I go home and rest. They would call with updates. "No news is good news," they said.

 

So I said "goodbye" to Casey. Pet her for a long time. Told her I would see her later and that she was a good girl...and that everyone...and all the animals are looking forward to seeing her again. "I love you, Casey," was the last thing I said to her.

 

At 3, I called for an update. There was some progress, albeit small. But there were more issues (protein and electrolyte levels were low; clotting issues - she needed a plasma transfusion; red blood cell count was low; white blood cell count was low; etc. etc.). It was pretty dismal.

 

Around 7:00, I received a call from the U of M. Casey was arresting. Her heart rate was plummeting. Her breathing was labored. I could hear a dog whimpering loudly in the background. "Please tell me that isn't Casey," I said to the vet.

 

"No, that's another dog. Casey is quiet. It looks like she is making the choice to leave us. You have two choices: CPR or we can help her along by doing euthanasia. What would you like us to do?"

 

"Please take her out of her suffering. Euthanasia."

 

The vet immediately told the team what to do. "They are giving her the shot as we speak." Of course...then I start crying even more knowing that I'm not there holding her as she's dying. I had to end the phone call.

 

The other vet who worked with Casey from when she was admitted (11 hours earlier) called me back a few minutes later to explain what had happened in more detail.

 

So, at 7:05 p.m., Casey died. "You did everything you could for Casey. You gave her every opportunity to help her recover. I'm so sorry for your loss," the vet said.

 

Casey tried as hard as she could during and after the surgery. Teams of people tried to help her. It was just Casey's time to go.

 

She lived 12 years (would have been 13 in April). For a large-breed dog, that's like being a 94 year old human.

 

She had a great life. She was a devoted, loving, friendly dog. She loved to make snow angels. She was a good sport about wearing clothes and costumes the girls put her in. She loved the nature trail, chasing bunnies, and finding pheasants and watch them fly off from the tall grass.

 

She got to be around two other dogs (Montague and Sydne), six cats, horses, sheep, chickens, and turkeys. She was curious and loving towards new life on the farm...from the lambs and chicks...to Sophia and Olivia when they were infants to young girls.

 

She was one of the official "camp dogs" when I ran an art and farm camp for children here at the farm (she and Sydne were the two dogs here at the time). She touched the lives of literally hundreds of children, teens, and adults through that program. There were children who were very fearful of large dogs who, during their week at camp, overcame their fear of dogs thanks to Casey.

 

Needless to say, last night was a VERY sad. Lots of tears.

 

This morning, I took Casey's collar out from my bag for Montague. He heard the jingle of Casey's metal nametag. He immediately stopped eating breakfast and ran over, his tail wagging. Obviously thinking his friend was back. He looked sad as he sniffed her collar...realizing she was no longer there.

 

We all miss Casey. A lot.

Dr. Jennifer Williams, a NASA research chemical engineer, displays two fatigue samples that will be tested in the Plasma Rapid Oxidation Technique for Extending Component Tenability (PROTECT) experiments inside the Prototype Laboratory at NASA’s Kennedy Space Center in Florida on Nov. 2, 2022. Plasma electrolytic oxidation is a surface coating technology that produces oxide layers on the surface of light metals and their alloys to improve their performance characteristics. These coatings are tailored to provide a combination of characteristics such as corrosion protection, wear resistance, thermal management, extreme hardness, and fatigue performance. PROTECT is expected to demonstrate a 10 percent improved fatigue performance and a 70 percent improvement in corrosion characteristics on the interior of treated 3-D printed metallic parts when compared to non-treated parts. PROTECT could be applied to spacecraft and launch vehicles. Photo credit: NASA/Kim Shiflett

I've seen the videos of gummi bears (sugar) burning in potassium chlorate on the internet. I have a bit of potassium perchlorate around (after several weeks of electrolytic conversion of salt) so decided to try the same demonstration with that.

 

Basically you melt the oxidizer and drop in the gummi bear. I wore a face shield during the experiment since I had never done it before. It's apparently a predictable event since I did it four times with no problems.

 

I got my trellis painted and it looks good. Maybe when the day cools off some more I'll transplant a few tomatoes and sow some pumpkin seeds.

 

Cheers.

Triumph Stag (1970-77) Engine 2997cc V8 OC Total Production 25,877 (of which 6780 were exported to the USA)

Registration Number XTP 805 L

TRIUMPH SET

www.flickr.com/photos/45676495@N05/sets/72157623847263736...

Built as a 2 door 2+2, convertible or hardtop. Originally conceived as a short chassis open top version of the Triumph 2000, but ended with a monocoque and a V8 engine of 145bhp not shared with any other Triumph. Overdrive at first optional, becoming standard in 1972, and many with Automatics.

The car initially received an enthusiastic welcome, but suffered from engine reliability problems, attributed to several design faults, firstly a coolant problem caused by the water pump being set above the engine, if coolant was lost via via the expansion bottle, the coolant level droppedbelow the level of the pump resulting in loss of fluid to the pump and water pump failure. Water pump failures also occurred due to poorly hardened drive gears, which wore out prematurely and stopped the water pump. Secondly the choice of materials, the engine block was constructed of iron and the heads of aluminium a combination that required the use of corrosion inhibiting anti freeze all year round a point often not realised by owners or the dealer network, resulting in cases of electrolytic corrosion, so that corroded alloy debris came loose and was distributed around inside the engine. A third cause of trouble was the engine's use of long, simplex roller link chains, which would first stretch and then often fail inside fewer than 25,000 miles , even before failure a stretched timing chain could skip links causing valve and piston damage. Another problem with the cylinder heads was the arrangement of cylinder head fixing studs, half of which were vertical and the other half at an angle. The angled studs when heated and cooled, expanded and contracted at a different rate to the alloy heads, causing sideways forces which caused premature failure of the cylinder head gaskets. Subsequently these design and maintainance faults have been recognise and addressed by owners and a well maintained Stag is a very desirable classic.

During the production run modifications evolved and consequently in Stag circles different period car are referred to as "Early" Mk I 1970, the Mk I (1971–1972/3), Mk II (1973) and "Late" Mk II (1974–1977), visually the Mark1s and Mk.2s differed only in the addition of twin coachlines to indicate Mk.II variants.

Bailey returned to the Vet today. He is in the early stages of kidney insufficiency.

 

His blood creatinine and sodium levels were elevated.

His white blood cell count was normal, indicating no infection, in his body.. ie bladder/kidneys.

 

His urine analysis, had blood in the urine, but no bacteria, or crystals. So no infection.

 

His blood pressure was also elevated today, taking into account the vet "fear factor."

 

So he was put on 1) Fortekor tablets (benazaprilhydrochloride... 2nd generation angiotensinn converting enzyme (ACE) inhibitor) 2.5 mg a day.

If his blood pressure remains high it could further stress/damage his kidneys.

 

2) an electrolyte solution (chicken flavor! ;) to add to his food 75 cc's a day.

 

3) KD = Science diet wet food... so we can easily add the electrolyte sol.

  

We will return in 2 weeks to have hi BP rechecked, and in one month for a recheck of his blood tests.

 

The vet definitely feels his spraying problem was NOT related to his high blood creatinine. I have all copies of all his labs from last Dec to now. They were all normal even when he was spraying.... with the exception of yesterday's blood work.

  

TODAY... He seems to be feeling a bit better. I even got him to purr, and he showed some interest in his fave toy.... Cat Prancer toy....(Cardboard thingy on a wire)

 

He LOVED his wet KD food mixed with the electrolyte sol. and his BP pill.

So this is ALL a plus!!!!! :-))

 

Again thanks to all my Flickr friends for all the love and support you've shown me and my Bailey Boy.... and Jakey too.

 

Thanks for all the emails as well. I will try to email you back as soon as I can.

 

Bailey Boy and me are resting together on my bed now.

 

I just got a cortisone injection in my left knee, and booked surgery for October. ;-(

 

What a pair.. LOL.

Thank goodness for "normal" Jake. :-D

A Candelabra That I Have Restored

 

Restored EPNS Candlesticks

 

Most silver plated cutlery and hollow ware is marked 'E.P.N.S.' - the abbreviation for 'Electro-Plated Nickel-Silver'. 'Nickel-Silver' identifies the base metal as a copper-zinc-nickel alloy; it contains no silver but, because its nickel content imparts a colour more akin to silver than brass, it has always been known as 'nickel-silver'. 'Electro-plated' in this context means that the articles are electro-plated with silver - the first metal to be used extensively in electro-plating. In many countries including USA, nickel silver is not used, but brass is used instead.

 

Stainless steel cutlery or hollowware is sometimes silver plated, in which case it may be marked 'E.P.S.S.'. Knife blades with a cutting edge are made from stainless and are not plated with silver because it would blunt their edges. The life of silver plate depends upon its thickness and how often it is used. A household that saves its silver plated cutlery for special occasions may use it on average only once a month - elsewhere it may be used several times a day. When selecting cutlery, it is advisable to compare the thickness of silver claimed to be present on each and every piece (averages based upon half a dozen pieces are less meaningful because some pieces are likely to have a significantly thinner silver thickness than that average). Silver thickness is normally quoted in 'microns'. (One micron is one thousandth of a millimeter). As a very approximate guide, work on at least 1 micron of silver thickness for every year of intended use.

 

CARE OF SILVER

 

The characteristic white 'patina' of silver which is responsible for much of its aesthetic appeal becomes more pronounced with age due to the optical effect of the multitude of very fine scratches that develop in use. On new highly polished silver, however, the few fine isolated scratches that first appear tend to be somewhat conspicuous until the white patina has fully developed.

 

Tarnish

 

Silver, being a noble metal, is highly resistant to corrosion, but it can be tarnished by sulphides that are always present to some extent in the atmosphere and in many foods, green vegetables and eggs being the most potent. Tarnish consists of a superficial film of silver sulphides. Initially it is a light gold colour, but, with prolonged exposure to sulphides, it can develop into a blue-black discolouration.

 

Sulphides in the atmosphere originate mainly from combustion of gas oil, coke, wood etc. and from living creatures. To avoid the need for frequent cleaning, it is best to store silver cutlery in a box or drawer in a room without a fire of any type and, if convenient, in one of the lesser used rooms. To avoid tarnishing by food, rinse it off the cutlery as soon as convenient. Tarnish resisting papers and cloths are available to store silver, which certainly reduce the rate of tarnishing.

 

Tarnish Removal

 

Four methods of detarnishing silver are available: polishing powders or pastes, chemical dip solutions, electrolytic methods and ball burnishing.

 

Polishing Powders and Pastes

 

Only those sold specifically for silver should be used; cleaners intended for chromium plate, stainless steel etc will scratch silver. Always apply the cleaner with a soft cloth or sponge - either of which should be thoroughly and freshly washed to eliminate any abrasive dust particles which could cause scratching.

 

Some cleaners that are available in paste or emulsion form, not only remove tarnish but contain tarnish inhibitors. Such products are particularly useful for hollowware (being handled, washed and wiped less frequently than cutlery, the inhibiting effect lasts longer).

 

Over zealous pressure when cleaning with powders may remove significant amounts of silver which ultimately will wear through the plate completely.

 

Chemical Dip Solutions (Often referred to as silver dip)

 

Provide a rapid, less arduous method of detarnishing, especially on heavily embossed designs whose crevices are difficult to clean with silver powders. These dip solutions convert the film of tarnish (silver sulphides) back to silver by removing the sulphides without removing any silver. However, the following precautions must be taken:

 

- (1) Never leave silver plated cutlery in the dip solution for more than 10 seconds.

 

- (2) Do not use dip solutions to remove very heavy tarnish. They will convert the silver sulphides to silver but, because heavy tarnish is thicker, the surface of the restored silver may have a matt finish.

 

- (3) Dip solutions can stain or even etch stainless steel knife blades. Any drops that fall onto blades or other stainless steel equipment should be rinsed off immediately.

 

Electrolytic Methods

 

Tarnish can be removed from silver by immersing it in a hot solution of washing soda of about 30 grams per 5 litres whilst the cutlery or hollowware is in contact with aluminium.

 

Proprietary kits are available but the process can be carried out on a DIY basis in a plastic bowl with a sheet of aluminium foil laid in the bottom so that the cutlery is in contact with the foil. When the foil eventually darkens and becomes brittle, it becomes ineffective and needs replacing.

 

As in the case of chemical dip solutions, the process is not suitable for use on very heavily tarnished silver upon which it can produce a dull white finish.

 

Ball Burnishing

 

This is a bulk process for use in large catering establishments. The cutlery is placed in a rotating drum containing steel ball bearings, water and a corrosion inhibitor to prevent the steel balls from rusting. Its prime purpose is to brighten and harden the surface so that it becomes more resistant to scratching and wear. However, it will also remove light to moderate tarnish, except in the crevices of heavily patterned pieces.

 

Despite the apparent severity of the process, it does not wear off the silver if carried out under intelligent supervision and in accordance with the machine supplier's instructions. Problems likely to occur are:

 

Entanglement of fork prongs which may cause some to bend. This can be avoided by positioning the compartment separators closer together so that the forks stay orientated across the barrel.

 

A matt scratched finish, caused by having insufficient water in the burnisher - this can occur as a result of leakage if the machine's lid has not been adequately tightened or if its seal is defective.

 

Developments of grooves on the sides of vessels such as tea post. This is caused by the compartment separators being too close together, thus allowing steel balls to become entrapped between the separators and the sides of the vessel - to the detriment of the latter. Compartment widths should be adjusted to suit the width of vessel being burnished.

 

Hollowware can be damaged if large heavy items are burnished in the same compartment.

 

Silver cutlery should be washed thoroughly after cleaning.

 

CARE OF STAINLESS STEEL CUTLERY

 

Stains

 

First, it must be emphasised that staining is a rare phenomenon and that in most cases it is due to something that becomes firmly deposited on the steel, rather than to any attack of the steel itself. Probably the most common cause of staining is attack by one of the proprietary dip solutions used for removing tarnish from silver. Although excellent for cleaning silver and E.P.N.S., these solutions should never be allowed to come into contact with stainless steel; they contain acids that etch the steel, first giving it an iridescent rainbow stain and ultimately etching it a dull grey. Even if care is taken to dip only the silver handle of a knife, it is so easy, when lifting it from the solution, to let drips fall onto the stainless steel blades of other cutlery that happen to be lying around.

All tap water contains dissolved mineral salts that would leave an extremely thin film on any article on which it was allowed to dry out without wiping. In most cases, the resultant stain will wipe off, but occasionally more vigorous treatment is needed, using a polishing preparation, such as stainless steel cleaners.

 

Detergents, especially unnecessarily strong solutions of detergent, can leave an indelible rainbow stain on stainless steel if they are not rinsed off and are allowed to dry, out on its surface. This is a common problem with some dishwashing machines when the rinse cycle is malfunctioning.

 

Very hard water can deposit a chalky film on stainless steel, but this is only likely to occur in dishwashers that use un-softened or incompletely softened water.

 

Very hot grease, fat or meat juices sometimes leave stubborn rainbow coloured stains on stainless steel, but this is more likely to occur on meat dishes than cutlery - again this does not mean there is anything wrong this the stainless steel and the articles will be as good as new after the stain has been removed.

 

Heat by itself will impart a rainbow coloured heat tint to stainless steel, but this is only likely to occur if the cutlery is accidentally left on a hot plate or gas burner, when the cause would be immediately obvious.

 

Prolonged immersion in synthetic 'vinegar' (condiment) can stain stainless steel knives if left on for several hours, but more rapidly if the 'vinegar' also contains salt.

 

Sometimes rust coloured stains occur. Wet fragments of steel wool that find their way onto cutlery may go rusty and leave indelible rust stains on the stainless steel. Other rust coloured stains may come from corrosion pits in the cutlery, although the pits themselves may be so small as to be barely visible.

 

Most stains that resist ordinary rubbing with a soapy cloth can be removed with stainless steel cleaners.

 

Finally, it must be pointed out that there may be other causes of staining that have not yet been identified.

 

Pits

 

When stainless steel corrodes, it does not rust all over like non stainless steel but acquires small localised pits or holes. Remember its STAIN LESS steel which means it will rust or corroded under some circumstances.

 

The majority of spoons and forks are made from stainless steels that have such excellent corrosion resistance that they are virtually immune to pitting. For knives, however, the blade steel is selected to give a compromise between corrosion resistance and cutting properties. In order to achieve a lasting edge, a steel that is much harder but of lower corrosion resistance that spoon and fork steel is used. The corrosion resistance of this steel is strongly influenced by care in manufacture (thorough hardening and avoidance of overheating when grinding etc) but only marginal improvements are achieved by the selection of alternative steels, however, expensive. Research is continually being carried out in the search for significantly better steels and method of treatment.

 

Prolonged contact with water is probably responsible for more pitting trouble than anything else. Knives have been made from stainless steel for such a long time that the highly corrosive effect of tap water, caused by the traces of mineral salts it contains is not appreciated. Why then do blades in one establishment last for years without trouble, whilst in others pitting becomes apparent within a few months? The answer lies in the length of time the blades are wet; knives that are left undried or actually immersed in water overnight can receive, in this time, as much exposure to the corrosive effect of water as three or four months' ordinary use where they are in contact with water for only a few minutes each time they are washed.

 

Common salt and liquid bleaches or disinfectants are very corrosive and will greatly accelerate the corrosive action of water. Some water softeners are regenerated with salt. If they are not functioning correctly, the softened water can have a high salt content. After adding salt to water softeners in a dishwasher, make certain that it is put through the rinse programme recommended by the supplier before washing knives in the machine. Detergents, on the other hand, are normally harmless when fully dissolved - indeed they often inhibit corrosion by water. If, however, certain powder detergents are allowed to come into contact with blades in hot water before the detergent is fully dissolved, pits and/or stains can form within a few minutes. Un-dissolved table salt can have a similar effect.

 

If pitting does occur, a diligent enquiry into the washing procedure is recommended to find out whether the cutlery is ever left in contact with water for a long item. Managers of catering establishments are not always aware of what really happens in their kitchens - for example, probably only the person directly involved may know that dirty cutlery is always left soaking in a bucket of water until someone has time to wash it, or that the last batch of knives to be washed in the early hours is left unwiped to dry overnight in a humid basement.

 

WASHING CUTLERY IN DISHWASHERS

 

Dishwashing machines provide a welcome relief from the task of washing up but to maintain knives in good condition a few simple precautions are necessary. Special hardenable stainless steels are generally used for knives to give them a lasting edge but these steels can become slightly pitted or corroded if left repeatedly and for too long in contact with moisture.

- Whenever possible wash knives immediately; do not leave them wet overnight and do not subject knives to the 'rinse and hold' cycle. The use of the dishwasher as a dirty storage cabinet causes many cases of knife corrosion.

- As soon as the dishwasher has completed its cycle, remove the knives and wipe them dry. It is particularly undesirable to leave them overnight in the damp atmosphere of a dishwasher.

- Observe the dishwasher manufacturer's instructions concerning the type and quality of detergent used and the method of loading cutlery in the compartments provided.

- Water with a high salt content is particularly corrosive to stainless steel. Dishwashers are often fitted with water softeners that must be regenerated with salt. After adding salt, make certain that the machine is put through the programme recommended by the supplier before washing knives in the machine.

- Cutlery with handles of wood, plastic, bone or china should be washed by hand unless it is stated to be suitable for dishwashers.

- If any stains are produced by hard water, detergent or by any other cause, they can usually be removed by rubbing them with a non-abrasive metal cleaning paste or liquid. Detergent stains can often occur with regular dishwasher use and show themselves as rainbow like stains, these can easily be removed with lemon juice.

- Do not allow undiluted dishwasher detergent to come into contact with silver or silver plated items as this may result in permanent staining of the surface. Some dishwasher manufacturers are not aware of this and position the cutlery basket immediately below the detergent dispenser.

- Do don't place silver plated or silver cutlery in at the same time stainless steel items, as it can increase the risk of the stainless steel corroding. Don't place knives with silver/ silver plated handles in the dishwasher at all.

MacSimski purchased a broken 1930's Philips 529 HU vacuum tube radio at a flea market. When opening it up, he found a molten capacitor. After replacing it with a modern (Philips!) replacement part, he managed to get a bit of sound out of it. The radio probably needs some more fine-tuning and a few part replacements. For instance, the electrolytic capacitor has dried out and lost its function. The entire unit also needs quite a bit of cleaning. Most of the wiring is deteriorated and previously flexible material has gone stiff and brittle.

I made the chain portion of this bracelet from jump rings made from upcycled 14 gauge electrical wire. (My husband made the jump rings.)

 

The small Czech glass beads were attached using my handmade 20 gauge rosy copper headpins.

 

I fashioned a button clasp from a disc that I electrolytically etched with a design found in a vintage metalsmithing text. The disc was domed and I then soldered a shank inside and copper plated the silver solder seams. The hook portion of the clasp was formed from a short length of torch balled 18 gauge wire. The bracelet was finished with one of my custom etched copper dragonfly logo charms.

 

The bracelet was treated with liver of sulphur and hand polished.

Nice bit of UN number spotting here.

 

The UN numbers range from UN0001 to about UN3600 and are assigned by the United Nations Committee of Experts on the Transport of Dangerous Goods.

 

UN1824 = Sodium hydroxide solution.

 

"At room temperature, sodium hydroxide is a white crystalline odorless solid that absorbs moisture from the air. It is a manufactured substance. When dissolved in water or neutralized with acid it liberates substantial heat, which may be sufficient to ignite combustible materials. Sodium hydroxide is very corrosive. It is generally used as a solid or a 50% solution. Other common names include caustic soda and lye. Sodium hydroxide is used to manufacture soaps, rayon, paper, explosives, dyestuffs, and petroleum products. It is also used in processing cotton fabric, laundering and bleaching, metal cleaning and processing, oxide coating, electroplating, and electrolytic extracting. It is commonly present in commercial drain and oven cleaners."

Thank you ~ to Bon & Han . . who both jumped-in to the comment-box within seconds of the photo appearing . . . I'm O.K. now, thanks to the wonderful treatment I received today at the U.M.C. ~

The "University Medical Centre" . . . a state-of-the-art Research Institute, Doctors' Training College, and District Hospital . . . all in one vast building, run by the de-la-Salle University, across the road !!

 

I had a bad stomach-upset mid-week ~ and expected a plain diet to put it right quickly . . .

But unfortunately, it got much worse ~ leading to Diarrhoea & sickness by the weekend.

My family here insisted on taking me to U.M.C. ~ where I spent most of Sunday, being thoroughly

tested, assessed, and diagnosed !

 

I told the young doctor that I never eat "street-corner-food" here, but that I am addicted to ice-skramble !!

He told me that ice-skramble is one of the commonest causes of tummy-trouble, because much of it is made using 'tap-water' ~ not purified drinking water !" . . and many manufacturers use cheap imported powdered skimmed-milk from China, which has not been Pasteurized !!

A further discussion with the doctor, after he had examined my 'samples', led us to conclude that my tummy-trouble was nothing to do with ice-skramble . . . in fact, it probably wasn't food-related !

They found Amoeboid parasites in my stools, of the kind which lurk in foul water in a stagnant river . . . so my attack may have been started by a bite from a mosquito ~ which had recently hatched near the sewage-works !!

 

I was examined within two minute of arriving at the Emergency-Unit . . and discharged five hours later with a raft of anti-biotics and 'electrolytes' to top-up my potassium deficiency.

This delightful little nurse, just 17 years old, is positioning the last few electrodes for my ECG.

The results were shown-to-me, and explained, on the spot . . . as the print-out appeared.

The results of the blood-tests were revealed six minutes later ( not sent to my G.P. next week !! )

 

Total cost was about 53-pounds-sterling . . . an amazing service . . .

They are light-years ahead of the U.K. !!!

About Hobart

Hobart is the state capital and most populous city of the Australian island state of Tasmania. Founded in 1803 as a penal colony, Hobart is Australia's second oldest capital city after Sydney. In 2009, the city had a greater area population of approximately 212,019. A resident of Hobart is known as a "Hobartian". The city is located in the state's south-east on the estuary of the Derwent River. The skyline is dominated by Mount Wellington at 1,271 metres high.

 

The city is the financial and administrative heart of Tasmania, and also serves as the home port for both Australian and French Antarctic operations.

 

Hobart was named Australia's 6th most sustainable city, by the Australian Conservation Foundation in 2010. For economic and social innovation, Hobart was the 11th placed in Australia in 2009, and listed as an innovation influencer city in the Innovation Cities Global Index scoring equal with Reykjavik, Katowice and Casablanca by 2thinknow.

 

About the Tasman Bridge

The Tasman Bridge is a five-lane bridge crossing the Derwent River, near the CBD of Hobart, Tasmania. The bridge has a total length (including approaches) of 1,395 metres (4,576 ft). It provides the main traffic route from the CBD (on the western shore) to the eastern shore - particularly Hobart International Airport and Bellerive Oval. It has a pedestrian foot way on each side, but no dedicated lane for bicycles. However, steps to the pedestrian foot way have recently been replaced with on-ramps.

 

On Sunday 5 January 1975, at 9:27 p.m. Australian Eastern Summer Time, the Tasman Bridge was struck by the bulk ore carrier Lake Illawarra, bound for the Electrolytic Zinc Company with a cargo of 10,000 tons of zinc concentrate. It caused two pylons and three sections of concrete decking, totaling 127 metres (417 ft), to fall from the bridge and sink the ship. Seven of the ship's crewmen were killed, and five motorists died when four cars drove over the collapsed sections before the traffic was stopped.

Soft Vinyl Mold Preparation

 

Continuing on from the previous section, now we look at how the molds are made for the soft vinyl outer shell.

 

1. Taking the 3D printouts of the body parts in the previous section, the next step is to make silicone molds which we will then use to make wax duplicates of the pieces. We then tie the two pieces of mold back together again and then pour in some hot wax.

 

2. Once the wax has cured, we can remove it from the silicon mold. Notice the wrist has a funnel attached - this is to enable us to pour in the soft vinyl when this eventually becomes a mold.

 

3. As soon as the wax copy is taken out of the silicone, the surfaces are rough and need to be polished down - if there are blemishes on the wax then it will end up being in the mold meaning anything made from the mold will also inherit blemishes.

 

4. Next up is preparing to make the wax copy into a mold and this is done in a process called Electroforming. Each part is first sprayed with graphite-based ink that makes it electrically conductive.

 

5. Each piece is has copper wire tied to it and hugh up to dry.

 

6. The wax copy is then dipped into an electrolytic bath. Deposits of copper then build up on the conductive surface to replicate the surface atom by atom.

 

7. Depending on the size of the wax piece, it can take a week for the copper to build up - this is the end result after the wax inside has been melted and poured away.

 

8. The copper molds are then welded on to a plate of metal called a "Frypan."

 

9. We currently only have one set of molds but discovered that we need to increase our mold count as we can't keep up with demands with this single set ><

 

10. The manufacturing process used to mold the body shell is called "Slush Casting." Here liquid vinyl is poured into one of the molds. The vinyl we use is the same material as other soft vinyl dolls on the market and does not pose any general risk to human health unless you eat or suck it - no sucking!

 

11. When the liquid vinyl is poured into the copper molds, air pockets get trapped in the liquid which must be removed - we do that by using a centrifugal separator which spins round for 30 seconds or so.

 

12. Even still, air pockets may be stubborn so they need to be removed using brute force - introducing a deaerator which removes all trace of oxygen from inside the chamber where the mold is placed.

 

13. The mold is the placed in a bath of oil which has been heated up to about 180 - 190 Celsius. The thickness of the doll piece is determined by how long you leave the mold in the oil. The heat penetrates through the mold and heats up the vinyl closest to the inner wall of the mold.

 

14. The copper mold is then placed into a cold water bath to cool down.

 

15. Next we need to pull the part out of the mold - pull to early and the part could end up being stretched - pull too late and it could be too hard to pull out or end up being damaged.

 

16. The mold has hoops attached - a slight change in the angle of the hoops affects the quality of the pull.

 

17. And this a hand freshly pulled from the mold - we then need to cut off the flash which is the funnel attached to it.

 

18. Together with the boss of mold maker Kamijo who have won awards for the quality of their molds.

 

19. This has nothing to do with soft vinyl but wanted to show you how we made the frame prototypes at one stage - we would use 3D printouts and copy them using silicone molds.

 

20. Some resin frame parts ready to be cut off the runners.

Scentless Apprentice

 

Like most babies smell like butter

his smell smelled like no other

he was born scentless and senseless

he was born a scentless apprentice

 

Go away - get away, get away, get a-way

every wet nurse refused to feed him

electrolytes smell like semen

 

I promise not to sell your perfumed secrets

there are countless formulas for pressing flowers

 

I lie in the soll and fertilize mushrooms

Leaking out gas fumes are made into perfume

 

You can't fire me because I quit

Throw me in the fire and I won't throw a fit

Mary Amanda Turney was born 10 January 1851 in Brooklyn, New York, the daughter of James Turney (1813-1895) and Catherine Ann Bogardus (born circa 1828). James Turney was a skilled electrotypist (one who duplicates a printing plate made by electrolytically depositing a layer of copper or nickel onto a mould of the original) in Brooklyn for over 20 years. Mary Turney was married on 23 November 1875 to Adam Hill (1838-1915), who was a buyer of metals for manufacturing. In 1880, the couple was living in Brookyn with Mary’s parents. Mary Amanda Turney passed away in 1891.

Fangruida: human landing on Mars 10 cutting-edge technology

[Fangruida- human landing on Mars 10 innovative and sophisticated technologies]

Aerospace Science and space science and technology major innovation of the most critical of sophisticated technology R & D project

-------------------------------------------------- -------------

Aerospace Science Space Science and Technology on behalf of the world's most cutting-edge leader in high technology, materials, mechatronics, information and communication, energy, biomedical, marine, aviation aerospace, microelectronics, computer, automation, intelligent biochips, use of nuclear energy, light mechanical and electrical integration, astrophysics, celestial chemistry, astrophysics and so a series of geological science and technology. Especially after the moon landing, the further development of mankind to Mars and other planets into the powerful offensive, the world's major powers eager to Daxian hand of God, increase investment, vigorously develop new sophisticated technology projects for space to space. Satellite, space station, the new spacecraft, the new space suits, the new radiation protection materials, intelligent materials, new manufacturing technology, communications technology, computer technology, detector technology, rover, rover technology, biomedical technology, and so one after another, is expected to greater breakthroughs and leaps. For example, rocket technology, spacecraft design, large power spacecraft, spacesuits design improvements, radiation multifunctional composite materials, life health care technology and space medicine, prevention against microgravity microgravity applicable drugs, tracking control technology, landing and return technology. Mars lander and returned safely to Earth as a top priority. Secondly, Mars, the Moon base and the use of transforming Mars, the Moon and other development will follow. Whether the former or the latter, are the modern aerospace science, space science basic research, applied basic research and applied research in the major cutting-edge technology. These major cutting-edge technology research and innovation, not only for human landing on Mars and the safe return of great significance, but for the entire space science, impact immeasurable universe sciences, earth sciences and human life. Here the most critical of the most important research projects of several sophisticated technology research and development as well as its core technology brief. Limit non-scientific techniques include non-technical limits of technology, the key lies in technology research and development of technology maturity, advanced technology, innovative, practical, reliable, practical application, business value and investment costs, and not simply like the idea mature technology achievements, difficult to put into things. This is the high-tech research and development, testing, prototype, test application testing, until the outcome of industrialization. Especially in aerospace technology, advanced, novelty, practicality, reliability, economy, maturity, commercial value and so on. For technical and research purely science fiction and the like may be irrelevant depth, but not as aerospace engineering and technology practice. Otherwise, Mars will become a dream fantasy, and even into settling crashed out of danger.

Regardless of the moon or Mars, many technical difficulties, especially a human landing on Mars and return safely to Earth, technical difficulties mainly in the following aspects. (Transformation of Mars and the Moon and other planets and detect other livable technology more complex and difficult, at this stage it is difficult to achieve and therefore not discussed in detail in this study). In fact, Mars will be the safe return of a full set of technology, space science, aerospace crucial scientific research development, its significance is not confined to Mars simply a return to scientific value, great commercial value, can not be measure.

1. Powered rocket, the spacecraft overall structural design not be too complex large, otherwise, the safety factor to reduce the risk of failure accidents. Fusion rocket engine main problem to be solved is the high-temperature materials and fuel ignition chamber (reaction chamber temperatures of up to tens of millions of supreme billion degrees), fissile class rocket engine whose essence is the miniaturization of nuclear reactors, and placed on the rocket. Nuclear rocket engine fuel as an energy source, with liquid hydrogen, liquid helium, liquid ammonia working fluid. Nuclear rocket engine mounted in the thrust chamber of the reactor, cooling nozzle, the working fluid delivery and control systems and other components. This engine due to nuclear radiation protection, exhaust pollution, reactor control and efficient heat exchanger design and other issues unresolved. Electrothermal rocket engine utilizing heat energy (resistance heating or electric arc heating) working medium (hydrogen, amines, hydrazine ), vaporized; nozzle expansion accelerated after discharged from the spout to generate thrust. Static rocket engine working fluid (mercury, cesium, hydrogen, etc.) from the tank enter the ionization chamber is formed thrust ionized into a plasma jet. Electric rocket engines with a high specific impulse (700-2500 sec), extremely long life (can be repeated thousands of times a starter, a total of up to thousands of hours of work). But the thrust of less than 100N. This engine is only available for spacecraft attitude control, station-keeping and the like. One nuclear - power rocket design is as follows: Firstly, the reactor heats water to make it into steam, and then the high-speed steam ejected, push the rocket. Nuclear rocket using hydrogen as working substance may be a better solution, it is one of the most commonly used liquid hydrogen rocket fuel rocket carrying liquid hydrogen virtually no technical difficulties. Heating hydrogen nuclear reactor, as long as it eventually reaches or exceeds current jet velocity hydrogen rocket engine jet speed, the same weight of the rocket will be able to work longer, it can accelerate the Rockets faster. Here there are only two problems: First, the final weight includes the weight of the rocket in nuclear reactors, so it must be as light as possible. Ultra-small nuclear reactor has been able to achieve. Furthermore, if used in outer space, we can not consider the problem of radioactive residues, simply to just one proton hydrogen nuclei are less likely to produce induced radioactivity, thus shielding layer can be made thinner, injected hydrogen gas can flow directly through the reactor core, it is not easy to solve, and that is how to get back at high speed heated gas is ejected.

Rocket engine with a nuclear fission reactor, based on the heating liquid hydrogen propellant, rather than igniting flammable propellant

High-speed heavy rocket is a major cutting-edge technology. After all, space flight and aircraft carriers, submarines, nuclear reactors differ greatly from the one hand, the use of traditional fuels, on the one hand can be nuclear reactor technology. From the control, for security reasons, the use of nuclear power rocket technology, safe and reliable overriding indicators. Nuclear atomic energy in line with the norms and rules of outer space. For the immature fetal abdominal hatchery technology, and resolutely reject use. This is the most significant development of nuclear-powered rocket principle.

Nuclear-powered spaceship for Use of nuclear power are three kinds:

The first method: no water or air space such media can not be used propeller must use jet approach. Reactor nuclear fission or fusion to produce a lot of heat, we will propellant (such as liquid hydrogen) injection, the rapid expansion of the propellant will be heated and then discharged from the engine speed tail thrust. This method is most readily available.

The second method: nuclear reactor will have a lot of fast-moving ions, these energetic particles moving very fast, so you can use a magnetic field to control their ejection direction. This principle ion rocket similar to the tail of the rocket ejected from the high-speed mobile ions, so that the recoil movement of a rocket. The advantage of this approach is to promote the unusually large ratio, without carrying any medium, continued strong. Ion engine, which is commonly referred to as "electric rocket", the principle is not complicated, the propellant is ionized particles,

Plasma Engine

Electromagnetic acceleration, high-speed spray. From the development trend, the US research scope covers almost all types of electric thrusters, but mainly to the development of ion engines, NASA in which to play the most active intake technology and preparedness plans. "

The third method: the use of nuclear explosions. It is a bold and crazy way, no longer is the use of a controlled nuclear reaction, but to use nuclear explosions to drive the ship, this is not an engine, and it is called a nuclear pulse rocket. This spacecraft will carry a lot of low-yield atomic bombs out one behind, and then detonated, followed by a spacecraft propulsion installation disk, absorbing the blast pushing the spacecraft forward. This was in 1955 to Orion (Project Orion) name of the project, originally planned to bring two thousand atomic bombs, Orion later fetal nuclear thermal rocket. Its principle is mounted on a small rocket reactor, the reactor utilizing thermal energy generated by the propellant is heated to a high temperature, high pressure and high temperature of the propellant from the high-speed spray nozzle, a tremendous impetus.

Common nuclear fission technologies, including nuclear pulse rocket engines, nuclear rockets, nuclear thermal rocket and nuclear stamping rockets to nuclear thermal rocket, for example, the size of its land-based nuclear power plant reactor structure than the much smaller, more uranium-235 purity requirements high, reaching more than 90%, at the request of the high specific impulse engine core temperature will reach about 3000K, require excellent high temperature properties of materials.

Research and test new IT technologies and new products and new technology and new materials, new equipment, things are difficult, design is the most important part, especially in the overall design, technical solutions, technical route, technical process, technical and economic particularly significant. The overall design is defective, technology there are loopholes in the program, will be a major technical route deviation, but also directly related to the success of research trials. so, any time, under any circumstances, a good grasp of the overall control of design, technical design, is essential. otherwise, a done deal, it is difficult save. aerospace technology research and product development is true.

3, high-performance nuclear rocket

Nuclear rocket nuclear fission and fusion energy can rocket rocket two categories. Nuclear fission and fusion produce heat, radiation and shock waves and other large amounts of energy, but here they are contemplated for use as a thermal energy rocket.

Uranium and other heavy elements, under certain conditions, will split their nuclei, called nuclear fission reaction. The atomic bomb is the result of nuclear fission reactions. Nuclear fission reaction to release energy, is a million times more chemical rocket propellant combustion energy. Therefore, nuclear fission energy is a high-performance rocket rockets. Since it requires much less propellant than chemical rockets can, so to its own weight is much lighter than chemical rockets energy. For the same quality of the rocket, the rocket payload of nuclear fission energy is much greater than the chemical energy of the rocket. Just nuclear fission energy rocket is still in the works. 

Use of nuclear fission energy as the energy of the rocket, called the atomic rockets. It is to make hydrogen or other inert gas working fluid through the reactor, the hydrogen after the heating temperature quickly rose to 2000 ℃, and then into the nozzle, high-speed spray to produce thrust. 

A vision plan is to use liquid hydrogen working fluid, in operation, the liquid hydrogen tank in the liquid hydrogen pump is withdrawn through the catheter and the engine cooling jacket and liquid hydrogen into hydrogen gas, hydrogen gas turbine-driven, locally expansion. Then by nuclear fission reactors, nuclear fission reactions absorb heat released, a sharp rise in temperature, and finally into the nozzle, the rapid expansion of high-speed spray. Calculations show that the amount of atomic payload rockets, rocket high chemical energy than 5-8 times.

Hydrogen and other light elements, under certain conditions, their nuclei convergent synthesis of new heavy nuclei, and release a lot of energy, called nuclear fusion reaction, also called thermonuclear reaction. 

Using energy generated by the fusion reaction for energy rocket, called fusion energy rocket or nuclear thermal rockets. But it is also not only take advantage of controlled nuclear fusion reaction to manufacture hydrogen bombs, rockets and controlled nuclear fusion reaction needs still studying it.

Of course there are various research and development of rocket technology and technical solutions to try.

It is envisaged that the rocket deuterium, an isotope of hydrogen with deuterium nuclear fusion reaction of helium nuclei, protons and neutrons, and release huge amounts of energy, just polymerized ionized helium to temperatures up to 100 million degrees the plasma, and then nozzle expansion, high-speed ejection, the exhaust speed of up to 15,000 km / sec, atomic energy is 1800 times the rocket, the rocket is the chemical energy of 3700 times.

Nuclear rocket engine fuel as an energy source, with liquid hydrogen, liquid helium, liquid ammonia working fluid. Nuclear rocket engine mounted in the thrust chamber of the reactor, cooling nozzle, the working fluid delivery and control systems and other components. In a nuclear reactor, nuclear energy into heat to heat the working fluid, the working fluid is heated after expansion nozzle to accelerate to the speed of 6500 ~ 11,000 m / sec from the discharge orifice to produce thrust. Nuclear rocket engine specific impulse (250 to 1000 seconds) long life, but the technology is complex, apply only to long-term spacecraft. This engine due to nuclear radiation protection, exhaust pollution, reactor control and efficient heat exchanger design and other issues not resolved, is still in the midst of trials. Nuclear rocket technology is cutting-edge aerospace science technology, centralized many professional and technical sciences and aerospace, nuclear physics, nuclear chemistry, materials science, the long term future ___-- wide width. The United States, Russia and Europe, China, India, Japan, Britain, Brazil and other countries in this regard have studies, in particular the United States and Russia led the way, impressive. Of course, at this stage of nuclear rocket technology, technology development there are still many difficulties. Fully formed, still to be. But humanity marching to the universe, nuclear reactor applications is essential.

2. radiation. Space radiation is one of the greatest threats to the safety of the astronauts, including X-rays, γ-rays, cosmic rays and high-speed solar particles. Better than aluminum protective effect of high polymer composite materials.

3. Air. Perhaps the oxygen needed to rely on oxidation-reduction reaction of hydrogen and ilmenite production of water, followed by water electrolysis to generate oxygen. Mars oxygen necessary for survival but also from the decomposition of water, electrolytically separating water molecules of oxygen and hydrogen, this oxygen equipment has been successfully used in the International Space Station. Oxygen is released into the air to sustain life, the hydrogen system into the water system.

4. The issue of food waste recycling. At present, the International Space Station on the use of dehumidifiers, sucked moisture in the air to be purified, and then changed back to drinkable water. The astronauts' urine and sweat recycling. 5. water. The spacecraft and the space station on purification system also makes urine and other liquids can be purified utilization. 6. microgravity. In microgravity or weightlessness long-term space travel, if protective measures shall not be treated, the astronauts will be muscle atrophy, bone softening health. 7. contact. 8. Insulation, 9 energy. Any space exploration are inseparable from the energy battery is a new super hybrid energy storage device, the asymmetric lead-acid batteries and supercapacitors in the same compound within the system - and the so-called inside, no additional separate electronic control unit, this is an optimal combination. The traditional lead-acid battery PbO2 monomer is a positive electrode plate and a negative electrode plate spongy Pb composition, not a super cell. : Silicon solar cells, multi-compound thin film solar cells, multi-layer polymer-modified electrode solar cells, nano-crystalline solar cells, batteries and super class. For example, the solar aircraft .10. To protect the health and life safety and security systems. Lysophosphatidic acid LPA is a growth factor-like lipid mediators, the researchers found that this substance can on apoptosis after radiation injury and animal cells was inhibited. Stable lysophosphatidic acid analogs having the hematopoietic system and gastrointestinal tract caused by acute radiation sickness protection, knockout experiments show that lysophosphatidic acid receptors is an important foundation for the protection of radiation injury. In addition to work under high pressure, the astronauts face a number of health threats, including motion sickness, bacterial infections, blindness space, as well as psychological problems, including toxic dust. In the weightless environment of space, the astronaut's body will be like in preadolescents, as the emergence of various changes.

Plantar molt

After the environment to adapt to zero gravity, the astronaut's body will be some strange changes. Weightlessness cause fluid flow around the main flow torso and head, causing the astronauts facial swelling and inflammation, such as nasal congestion. During long-term stay in space

Bone and muscle loss

Most people weightlessness caused by the impact may be known bone and muscle degeneration. In addition, the calcium bones become very fragile and prone to fracture, which is why some of the astronauts after landing need on a stretcher.

Space Blindness

Space Blindness refers astronaut decreased vision.

Solar storms and radiation is one of the biggest challenges facing the long-term space flight. Since losing the protection of Earth's magnetic field, astronauts suffer far more than normal levels of radiation. The cumulative amount of radiation exposure in low earth orbit them exceeded by workers close to nuclear reactors, thereby increasing the risk of cancer.

Prolonged space flight can cause a series of psychological problems, including depression or mood swings, vulnerability, anxiety and fear, as well as other sequelae. We are familiar with the biology of the Earth, the Earth biochemistry, biophysics, after all, the Earth is very different astrophysics, celestial chemistry, biophysics and astrophysics, biochemistry and other celestial bodies. Therefore, you must be familiar with and adapt to these differences and changes.

Osteoporosis and its complications ranked first in the space of disease risk.

Long-term health risks associated with flying Topics

The degree of influence long-term biological effects of radiation in human flight can withstand the radiation and the maximum limit of accumulated radiation on physiology, pathology and genetics.

Physiological effects of weightlessness including: long-term bone loss and a return flight after the maximum extent and severity of the continued deterioration of other pathological problems induced by the; maximum flexibility and severity of possible long-term Flight Center in vascular function.

Long-term risk of disease due to the high risk of flight stress, microbial variation, decreased immune function, leading to infections

Radiation hazards and protection

1) radiation medicine, biology and pathway effects Features

Radiation protection for interplanetary flight, since the lack of protective effect of Earth's magnetic field, and by the irradiation time is longer, the possibility of increased radiation hazard.

Analysis of space flight medical problems that may occur, loss of appetite topped the list, sleep disorders, fatigue and insomnia, in addition, space sickness, musculoskeletal system problems, eye problems, infections problems, skin problems and cardiovascular problems

---------------------------------------------------------

Development of diagnostic techniques in orbit, the development of the volume of power consumption, features a wide range of diagnostic techniques, such as applied research of ultrasound diagnostic techniques in the abdominal thoracic trauma, bone, ligament damage, dental / sinus infections and other complications and integrated;

Actively explore in orbit disposal of medical technology, weightlessness surgical methods, development of special surgical instruments, the role of narcotic drugs and the like.

——————————————————————————————-

However, space technology itself is integrated with the use of the most advanced technology, its challenging technical reserves and periodic demanding

With the continuous development of science and technology, space agencies plan a manned landing on the moon and Mars, space exploration emergency medicine current concern.

Space sickness

In the weightless environment of space, in the weightless environment of space, surgery may be extremely difficult and risky.

Robot surgeons

Space disease in three days after entering the space started to ease, although individual astronauts might subsequently relapse. January 2015 NASA declared working on a fast, anti-nausea and nasal sprays. In addition, due to the zero-gravity environment, and anti-nausea drugs can only be administered by injection or transdermal patches manner.

Manned spaceflight in the 21st century is the era of interplanetary flight, aerospace medicine is closely watched era is the era of China's manned space flourish. Only the central issue, and grasp the opportunity to open up a new world of human survival and development.

Various emergency contingency measures in special circumstances. Invisible accident risk prevention. Enhancing drugs and other screening methods immunity aerospace medicine and tissue engineering a microgravity environment. Drug mixture of APS, ginseng polysaccharides, Ganoderma lucidum polysaccharides, polysaccharides and Lentinan, from other compounds. Drug development space syndrome drug, chemical structure modification will be an important part.

These issues are very sensitive, cutting-edge technology is a major difficulty landing on Mars. Countries in the world, especially the world's major space powers in the country strategies and technical research, the results of all kinds continue to emerge. United States, Russia, China, Europe, India, Japan and other countries is different. United States, Russia extraordinary strength. Many patented technology and health, and most belong to the top-secret technology. Especially in aerospace engineering and technological achievements is different from the general scientific literature, practical, commercial, industrial great, especially the performance of patents, know-how, technical drawings, engineering design and other aspects. Present Mars and return safely to Earth, the first manned, significance, everything is hard in the beginning, especially the first person to land on Mars This Mars for Human Sciences Research Mars, the moon, the earth, the solar system and the universe, life and other significant. Its far greater than the value of direct investments and business interests.

In addition, it is the development of new materials, suitable for deep space operations universe, life, and other detection, wider field.

Many aerospace materials, continuous research and development of materials are key areas of aerospace development, including material rocket, the spacecraft materials, the suit materials, radiation materials, materials and equipment, instruments, materials and so on biochemistry.

Temperature metal-based compound with a metal matrix composite body with a more primordial higher temperature strength, creep resistance, impact resistance, thermal fatigue and other excellent high temperature performance.

In B, C, SiC fiber reinforced Ti3Al, TiAl, Ni3Al intermetallic matrix composites, etc.

W Fiber Reinforced with nickel-based, iron-based alloys as well as SiC, TiB2, Si3N4 and BN particle reinforced metal matrix composites

High temperature service conditions require the development of ceramic and carbon-based composite materials, etc., not in this eleven Cheung said.

Fuel storage

In order to survive in space, people need many things: food, oxygen, shelter, and, perhaps most importantly, fuel. The initial quality Mars mission somewhere around 80 percent of the space launch humans will be propellant. The fuel amount of storage space is very difficult.

This difference in low Earth orbit cause liquid hydrogen and liquid oxygen - rocket fuel - vaporization.

Hydrogen is particularly likely to leak out, resulting in a loss of about 4% per month.

When you want to get people to Mars speed to minimize exposure to weightlessness and space radiation hazards

Mars

Landings on the Martian surface, they realized that they reached the limit. The rapid expansion of the thin Martian atmosphere can not be very large parachute, such as those that will need to be large enough to slow down, carry human spacecraft.

Therefore, the parachute strong mass ratio, high temperature resistance, Bing shot performance and other aspects of textile materials used have special requirements, in order to make a parachute can be used in rockets, missiles, Yu arrows spacecraft and other spacecraft recovery, it is necessary to improve the canopy heat resistance, a high melting point polymeric fiber fabric used, the metal fabric, ceramic fiber fabrics, and other devices.

Super rigid parachute to help slow the landing vehicle.

Spacecraft entered the Martian atmosphere at 24,000 km / h. Even after slowing parachute or inflatable, it will be very

Once we have the protection of the Earth magnetic field, the solar radiation will accumulate in the body, a huge explosion threw the spacecraft may potentially lethal doses of radiation astronauts.

In addition to radiation, the biggest challenge is manned trip to Mars microgravity, as previously described.

The moon is sterile. Mars is another case entirely.

With dust treatment measures.

Arid Martian environment to create a super-tiny dust particles flying around the Earth for billions of years.

Apollo moon dust encountered. Ultra-sharp and abrasive lunar dust was named something that can clog the basic functions of mechanical damage. High chloride salt, which can cause thyroid problems in people.

Mars geological structure and geological structure of the moon, water on Mars geology, geology of the Moon is very important, because he, like the Earth's geology is related to many important issues. Water, the first element of life, air, temperature, and complex geological formations are geological structure. Cosmic geology research methods, mainly through a variety of detection equipment equipped with a space probe, celestial observations of atmospheric composition, composition and distribution of temperature, pressure, wind speed, vertical structure, composition of the solar wind, the water, the surface topography and Zoning, topsoil the composition and characteristics of the component surface of the rock, type and distribution, stratigraphic sequence, structural system and the internal shell structure.

Mars internal situation only rely on its surface condition of large amounts of data and related information inferred. It is generally believed that the core radius of 1700 km of high-density material composition; outsourcing a layer of lava, it is denser than the Earth's mantle some; outermost layer is a thin crust. Compared to other terrestrial planets, the lower the density of Mars, which indicates that the Martian core of iron (magnesium and iron sulfide) with may contain more sulfur. Like Mercury and the Moon, Mars and lack active plate movement; there is no indication that the crust of Mars occurred can cause translational events like the Earth like so many of folded mountains. Since there is no lateral movement in the earth's crust under the giant hot zone relative to the ground in a stationary state. Slight stress coupled with the ground, resulting in Tharis bumps and huge volcano. For the geological structure of Mars is very important, which is why repeated explorations and studies of Martian geological reasons.

Crust

The outermost layer of the crust.

Crustal thickness obtained, the original thickness of the low north 40 km south plateau 70 kilometers thick, an average of 50 kilometers, at least 80 km Tharsis plateau and the Antarctic Plateau, and in the impact basin is thin, as only about 10 kilometers Greece plains.

Canyon of Mars there are two categories: outflow channels (outflow channel) and tree valley (valley network). The former is very large, it can be 100 km wide, over 2000 km long, streamlined, mainly in the younger Northern Hemisphere, such as the plain around Tyre Chris Canyon and Canyon jam.

In addition, the volcanic activity sometimes lava formation lava channels (lava channel); crustal stress generated by fissures, faults, forming numerous parallel extending grooves (fossa), such as around the huge Tharsis volcanic plateau radially distributed numerous grooves, which can again lead to volcanic activity.

Presumably, Mars has an iron as the main component of the nucleus, and contains sulfur, magnesium and other light elements, the nuclear share of Mars, the Earth should be relatively small. The outer core is covered with a thick layer of magnesium-rich silicate mantle, the surface of rocky crust. The density of Earth-like planets Mars is the lowest, only 3.93g / cc.

Lunar core

The average density of the Moon is 3.3464 g / cc, the solar system satellites second highest (after Aiou). However, there are few clues mean lunar core is small, only about 350 km radius or less [2]. The core of the moon is only about 20% the size of the moon, the moon's interior has a solid, iron-rich core diameter of about 240 kilometers (150 miles); in addition there is a liquid core, mainly composed of iron outer core, about 330 km in diameter (205 miles), and for the first time compared with the core of the Earth, considered as the earth's outer core, like sulfur and oxygen may have lighter elements [4].

Chemical elements on the lunar surface constituted in accordance with its abundance as follows: oxygen (O), silicon (Si), iron (Fe), magnesium (Mg), calcium (Ca), aluminum (Al), manganese (Mn), titanium ( Ti). The most abundant is oxygen, silicon and iron. The oxygen content is estimated to be 42% (by weight). Carbon (C) and nitrogen (N) only traces seem to exist only in trace amounts deposited in the solar wind brings.

Moon geological history is an important event in recent global magma ocean crystallization. The specific depth is not clear, but some studies have shown that at least a depth of about 500 kilometers or more.

Lunar landscape

Lunar landscape can be described as impact craters and ejecta, some volcanoes, hills, lava-filled depressions.

Regolith

TABLE bear the asteroid and comets billions of years of bombardment. Over time, the impact of these processes have already broken into fine-grained surface rock debris, called regolith. Young mare area, regolith thickness of about 2 meters, while the oldest dated land, regolith thickness of up to 20 meters. Through the analysis of lunar soil components, in particular the isotopic composition changes can determine the period of solar activity. Solar wind gases possible future lunar base is useful because oxygen, hydrogen (water), carbon and nitrogen is not only essential to life, but also may be useful for fuel production. Lunar soil constituents may also be as a future source of energy.

Here, repeatedly stressed that the geological structure and geological structure of celestial bodies, the Earth, Moon, Mars, or that this human existence and development of biological life forms is very important, especially in a series of data Martian geological structure geological structure is directly related to human landing Mars and the successful transformation of Mars or not. for example, water, liquid water, water, oxygen, synthesis, must not be taken lightly.

Mars landing 10 Technology

Aerospace Science and space science and technology major innovation of the most critical of sophisticated technology R & D project

[

"1" rocket propulsion technology ion fusion nuclear pulse propulsion rocket powered high-speed heavy rocket technology, space nuclear reactors spacecraft] brought big problems reflected in the nuclear reaction, nuclear radiation on spacecraft launch, control, brakes and other impact.

In particular, for the future of nuclear power spacecraft, the need to solve the nuclear reactor design, manufacture, control, cooling, radiation shielding, exhaust pollution, high thermoelectric conversion efficiency and a series of technical problems.

In particular, nuclear reactors produce radiation on astronauts' health will pose a great threat, which requires the spacecraft to be nuclear radiation shielding to ensure astronaut and ship the goods from radiation and heat from the reactor influence, but this will greatly increase the weight of the detector.

Space nuclear process applications, nuclear reaction decay is not a problem, but in a vacuum, ultra-low temperature environment, the nuclear reaction materials, energy transport materials have very high demands.

Space facing the reality of a nuclear reactor cooling cooling problems. To prevent problems with the reactor, "Washington" aircraft carrier to take four heavy protective measures for the radiation enclosed in the warship. These four measures are: the fuel itself, fuel storage pressure vessel, reactor shell and the hull. US Navy fuel all metal fuel, designed to take the impact resistance of the war, does not release fission product can withstand more than 50 times the gravity of the impact load; product of nuclear fission reactor fuel will never enter loop cooling water. The third layer of protection is specially designed and manufactured the reactor shell. The fourth layer is a very strong anti-impact combat ship, the reactor is arranged in the center of the ship, very safe. Engage in a reactor can only be loaded up to the aircraft, so as to drive the motor, and then drive the propeller. That is the core advantage of the heat generated by the heated gas flow, high temperature high pressure gas discharge backward, thereby generating thrust.

.

After installation AMPS1000 type nuclear power plant, a nuclear fuel assembly: He is a core member of the nuclear fuel chain reaction. Usually made into uranium dioxide, of which only a few percent uranium-235, and most of it is not directly involved in the nuclear fission of uranium 238. The uranium dioxide sintered into cylindrical pieces, into a stainless steel or a zirconium alloy do metal tubes called fuel rods or the original, then the number of fuel rods loaded metal cylinder in an orderly composition of the fuel assembly, and finally put a lot of vertical distribution of fuel assemblies in the reactor.

Nuclear reactor pressure vessel is a housing for containing nuclear fuel and reactor internals, for producing high-quality high-strength steel is made to withstand the pressure of dozens MPa. Import and export of the coolant in the pressure vessel.

The top of the pressure vessel closure, and can be used to accommodate the fixed control rod drive mechanism, pressure vessel head has a semi-circular, flat-topped.

Roof bolt: used to connect the locking pressure vessel head, so that the cylinder to form a completely sealed container.

Neutron Source: Plug in nuclear reactors can provide sufficient neutron, nuclear fuel ignition, to start to enhance the role of nuclear reactors and nuclear power. Neutron source generally composed of radium, polonium, beryllium, antimony production. Neutron source and neutron fission reactors are fast neutron, can not cause fission of uranium 235, in order to slow down, we need to moderator ---- full of pure water in a nuclear reactor. Aircraft carriers, submarines use nuclear reactor control has proven more successful.

Rod: has a strong ability to absorb neutrons, driven by the control rod drive mechanism, can move up and down in a nuclear reactor control rods within the nuclear fuel used to start, shut down the nuclear reactor, and maintain, regulate reactor power. Hafnium control rods in general, silver, indium, cadmium and other metals production.

Control rod drive mechanism: He is the executive body of nuclear reactors operating system and security protection systems, in strict accordance with requirements of the system or its operator control rod drives do move up and down in a nuclear reactor, nuclear reactor for power control. In a crisis situation, you also can quickly control rods fully inserted into the reactor in order to achieve the purpose of the emergency shutdown

Upper and lower support plate: used to secure the fuel assembly. High temperature and pressure inside the reactor is filled with pure water (so called pressurized water reactors), on the one hand he was passing through a nuclear reactor core, cooling the nuclear fuel, to act as a coolant, on the other hand it accumulates in the pressure vessel in play moderated neutrons role, acting as moderator.

Water quality monitoring sampling system:

Adding chemical system: under normal circumstances, for adding hydrazine, hydrogen, pH control agents to the primary coolant system, the main purpose is to remove and reduce coolant oxygen, high oxygen water suppression equipment wall corrosion (usually at a high temperature oxygen with hydrogen, especially at low temperatures during startup of a nuclear reactor with added hydrazine oxygen); when the nuclear reactor control rods stuck for some reason can not shutdown time by the the system can inject the nuclear reactor neutron absorber (such as boric acid solution), emergency shutdown, in order to ensure the safety of nuclear submarines.

Water system: a loop inside the water will be reduced at work, such as water sampling and analysis, equipment leaks, because the shutdown process cooling water and reduction of thermal expansion and contraction.

Equipment cooling water system:

Pressure safety systems: pressure reactor primary coolant system may change rapidly for some reason, the need for effective control. And in severe burn nuclear fuel rods, resulting in a core melt accident, it is necessary to promptly increase the pressure. Turn the regulator measures the electric, heating and cooling water. If necessary, also temporary startup booster pump.

Residual Heat Removal System: reactor scram may be due to an accident, such as when the primary coolant system of the steam generator heat exchanger tube is damaged, it must be urgently closed reactors.

Safety Injection System: The main components of this system is the high-pressure injection pump.

Radioactive waste treatment systems:

Decontamination Systems: for the removal of radioactive deposits equipment, valves, pipes and accessories, and other surfaces.

Europe, the United States and Russia and other countries related to aircraft carriers, submarines, icebreakers, nuclear-powered research aircraft, there are lots of achievements use of nuclear energy, it is worth analysis. However, nuclear reactor technology, rocket ships and the former are very different, therefore, requires special attention and innovative research. Must adopt a new new design techniques, otherwise, fall into the stereotype, it will avail, nothing even cause harm Aerospace.

Aerospace technology, space technology a lot, a lot of cutting-edge technology. Human landing on Mars technology bear the brunt. The main merge the human landing on Mars 10 cutting-edge technology, in fact, these 10 cutting-edge technology, covering a wide range, focused, and is the key to key technologies. They actually shows overall trends and technology Aerospace Science and Technology space technology. Human triumph Mars and safe return of 10 cutting-edge technology is bound to innovation. Moreover, in order to explore the human Venus, Jupiter satellites and the solar system, the Milky Way and other future development of science and laid the foundation guarantee. But also for the transformation of human to Mars, the Moon and other planets livable provides strong technical support. Aerospace Science and Technology which is a major support system.

Preparation of oxygen, water, synthesis, temperature, radiation, critical force confrontation. Regardless of the moon or Mars, survive three elements bear the brunt.

Chemical formula: H₂O

Formula: H-O-H (OH bond between two angle 104.5 °).

Molecular Weight: 18.016

Chemical Experiment: water electrolysis. Formula: 2H₂O = energized = 2H₂ ↑ + O₂ ↑ (decomposition)

Molecules: a hydrogen atom, an oxygen atom.

Ionization of water: the presence of pure water ionization equilibrium following: H₂O == == H⁺ + OH⁻ reversible or irreversible H₂O + H₂O = = H₃O⁺ + OH⁻.

NOTE: "H₃O⁺" hydronium ions, for simplicity, often abbreviated as H⁺, more accurate to say the H9O4⁺, the amount of hydrogen ion concentration in pure water material is 10⁻⁷mol / L.

Electrolysis of water:

Water at DC, decomposition to produce hydrogen and oxygen, this method is industrially prepared pure hydrogen and oxygen 2H₂O = 2H₂ ↑ + O₂ ↑.

. Hydration Reaction:

Water with an alkaline active metal oxides, as well as some of the most acidic oxide hydration reaction of unsaturated hydrocarbons.

Na₂O + H₂O = 2NaOH

CaO + H₂O = Ca (OH) ₂

SO₃ + H₂O = H₂SO₄

P₂O₅ + 3H₂O = 2H₃PO₄ molecular structure

CH₂ = CH₂ + H₂O ← → C₂H₅OH

6. The diameter of the order of magnitude of 10 water molecules negative power of ten, the water is generally believed that a diameter of 2 to 3 this organization. water

7. Water ionization:

In the water, almost no water molecules ionized to generate ions.

H₂O ← → H⁺ + OH⁻

Heating potassium chlorate or potassium permanganate preparation of oxygen

Pressurized at low temperatures, the air into a liquid, and then evaporated, since the boiling point of liquid nitrogen is -196 deg.] C, lower than the boiling point of liquid oxygen (-183 ℃), so the liquid nitrogen evaporated from the first air, remaining the main liquid oxygen.

Of course, the development of research in space there is a great difference, even more special preparation harsh environments on Earth and sy

Appalachian Trail north of Bull's Bridge, Connecticut.

 

I hiked Schaghticoke Ridge again from Rt. 341 in Kent south to Bull's Bridge and again didn't find a lot to shoot (or just didn't feel like shooting).

 

While on a water break near the end of the hike I looked up and found that I was in a small grove of beech trees. I attempted some shots looking up at their smooth trunks but they didn't work out. Small groups of leaves overhead were making interesting patterns as light passed through their overlapping layers and I took a few pictures as place markers as this type of shot needs more experimentation.

 

This is the high contrast black and white JPEG almost straight out of the Ricoh GR with the added grain. This in-camera processing gives small bits of contrast like the leaf veins a bit more contrast, which I like.

 

An aside: I've had a few leg cramps in the evening after big hikes like this and they were bad enough so that I did a bit of research on why I might be having them. It seems dehydration can cause cramps and while I drink enough water to "pee clear" I decided to try an electrolyte replacement called "Salt Stick."

 

I'm not a serious athlete (any more) but doing long hikes in the heat and humidity of summer can dehydrate anyone.

 

Bottom line: it really works. It's a gel-cap that's got sodium and potassium and a few other things in it but it's not Gatorade (ugh) and it doesn't need to be mixed with water, just swallowed. I took one each hour on the hike with plenty of water and there is no doubt that I felt better throughout the hike and afterwards. Less heavy legs, no cramps and I had more left at the end. If this is something you might be interested in, look up "Salt Stick" on Amazon.

Aerospace Science and space science and technology major innovation of the most critical of sophisticated technology R & D project

-------------------------------------------------- -------------

Aerospace Science Space Science and Technology on behalf of the world's most cutting-edge leader in high technology, materials, mechatronics, information and communication, energy, biomedical, marine, aviation aerospace, microelectronics, computer, automation, intelligent biochips, use of nuclear energy, light mechanical and electrical integration, astrophysics, celestial chemistry, astrophysics and so a series of geological science and technology. Especially after the moon landing, the further development of mankind to Mars and other planets into the powerful offensive, the world's major powers eager to Daxian hand of God, increase investment, vigorously develop new sophisticated technology projects for space to space. Satellite, space station, the new spacecraft, the new space suits, the new radiation protection materials, intelligent materials, new manufacturing technology, communications technology, computer technology, detector technology, rover, rover technology, biomedical technology, and so one after another, is expected to greater breakthroughs and leaps. For example, rocket technology, spacecraft design, large power spacecraft, spacesuits design improvements, radiation multifunctional composite materials, life health care technology and space medicine, prevention against microgravity microgravity applicable drugs, tracking control technology, landing and return technology. Mars lander and returned safely to Earth as a top priority. Secondly, Mars, the Moon base and the use of transforming Mars, the Moon and other development will follow. Whether the former or the latter, are the modern aerospace science, space science basic research, applied basic research and applied research in the major cutting-edge technology. These major cutting-edge technology research and innovation, not only for human landing on Mars and the safe return of great significance, but for the entire space science, impact immeasurable universe sciences, earth sciences and human life. Here the most critical of the most important research projects of several sophisticated technology research and development as well as its core technology brief. Limit non-scientific techniques include non-technical limits of technology, the key lies in technology research and development of technology maturity, advanced technology, innovative, practical, reliable, practical application, business value and investment costs, and not simply like the idea mature technology achievements, difficult to put into things. This is the high-tech research and development, testing, prototype, test application testing, until the outcome of industrialization. Especially in aerospace technology, advanced, novelty, practicality, reliability, economy, maturity, commercial value and so on. For technical and research purely science fiction and the like may be irrelevant depth, but not as aerospace engineering and technology practice. Otherwise, Mars will become a dream fantasy, and even into settling crashed out of danger.

 

Regardless of the moon or Mars, many technical difficulties, especially a human landing on Mars and return safely to Earth, technical difficulties mainly in the following aspects. (Transformation of Mars and the Moon and other planets and detect other livable technology more complex and difficult, at this stage it is difficult to achieve and therefore not discussed in detail in this study). In fact, Mars will be the safe return of a full set of technology, space science, aerospace crucial scientific research development, its significance is not confined to Mars simply a return to scientific value, great commercial value, can not be measure.

1. Powered rocket, the spacecraft overall structural design not be too complex large, otherwise, the safety factor to reduce the risk of failure accidents. Fusion rocket engine main problem to be solved is the high-temperature materials and fuel ignition chamber (reaction chamber temperatures of up to tens of millions of supreme billion degrees), fissile class rocket engine whose essence is the miniaturization of nuclear reactors, and placed on the rocket. Nuclear rocket engine fuel as an energy source, with liquid hydrogen, liquid helium, liquid ammonia working fluid. Nuclear rocket engine mounted in the thrust chamber of the reactor, cooling nozzle, the working fluid delivery and control systems and other components. This engine due to nuclear radiation protection, exhaust pollution, reactor control and efficient heat exchanger design and other issues unresolved. Electrothermal rocket engine utilizing heat energy (resistance heating or electric arc heating) working medium (hydrogen, amines, hydrazine ), vaporized; nozzle expansion accelerated after discharged from the spout to generate thrust. Static rocket engine working fluid (mercury, cesium, hydrogen, etc.) from the tank enter the ionization chamber is formed thrust ionized into a plasma jet. Electric rocket engines with a high specific impulse (700-2500 sec), extremely long life (can be repeated thousands of times a starter, a total of up to thousands of hours of work). But the thrust of less than 100N. This engine is only available for spacecraft attitude control, station-keeping and the like. One nuclear - power rocket design is as follows: Firstly, the reactor heats water to make it into steam, and then the high-speed steam ejected, push the rocket. Nuclear rocket using hydrogen as working substance may be a better solution, it is one of the most commonly used liquid hydrogen rocket fuel rocket carrying liquid hydrogen virtually no technical difficulties. Heating hydrogen nuclear reactor, as long as it eventually reaches or exceeds current jet velocity hydrogen rocket engine jet speed, the same weight of the rocket will be able to work longer, it can accelerate the Rockets faster. Here there are only two problems: First, the final weight includes the weight of the rocket in nuclear reactors, so it must be as light as possible. Ultra-small nuclear reactor has been able to achieve. Furthermore, if used in outer space, we can not consider the problem of radioactive residues, simply to just one proton hydrogen nuclei are less likely to produce induced radioactivity, thus shielding layer can be made thinner, injected hydrogen gas can flow directly through the reactor core, it is not easy to solve, and that is how to get back at high speed heated gas is ejected.

  

Rocket engine with a nuclear fission reactor, based on the heating liquid hydrogen propellant, rather than igniting flammable propellant

High-speed heavy rocket is a major cutting-edge technology. After all, space flight and aircraft carriers, submarines, nuclear reactors differ greatly from the one hand, the use of traditional fuels, on the one hand can be nuclear reactor technology. From the control, for security reasons, the use of nuclear power rocket technology, safe and reliable overriding indicators. Nuclear atomic energy in line with the norms and rules of outer space. For the immature fetal abdominal hatchery technology, and resolutely reject use. This is the most significant development of nuclear-powered rocket principle.

Nuclear-powered spaceship for Use of nuclear power are three kinds:

The first method: no water or air space such media can not be used propeller must use jet approach. Reactor nuclear fission or fusion to produce a lot of heat, we will propellant (such as liquid hydrogen) injection, the rapid expansion of the propellant will be heated and then discharged from the engine speed tail thrust. This method is most readily available.

The second method: nuclear reactor will have a lot of fast-moving ions, these energetic particles moving very fast, so you can use a magnetic field to control their ejection direction. This principle ion rocket similar to the tail of the rocket ejected from the high-speed mobile ions, so that the recoil movement of a rocket. The advantage of this approach is to promote the unusually large ratio, without carrying any medium, continued strong. Ion engine, which is commonly referred to as "electric rocket", the principle is not complicated, the propellant is ionized particles,

Plasma Engine

Electromagnetic acceleration, high-speed spray. From the development trend, the US research scope covers almost all types of electric thrusters, but mainly to the development of ion engines, NASA in which to play the most active intake technology and preparedness plans. "

The third method: the use of nuclear explosions. It is a bold and crazy way, no longer is the use of a controlled nuclear reaction, but to use nuclear explosions to drive the ship, this is not an engine, and it is called a nuclear pulse rocket. This spacecraft will carry a lot of low-yield atomic bombs out one behind, and then detonated, followed by a spacecraft propulsion installation disk, absorbing the blast pushing the spacecraft forward. This was in 1955 to Orion (Project Orion) name of the project, originally planned to bring two thousand atomic bombs, Orion later fetal nuclear thermal rocket. Its principle is mounted on a small rocket reactor, the reactor utilizing thermal energy generated by the propellant is heated to a high temperature, high pressure and high temperature of the propellant from the high-speed spray nozzle, a tremendous impetus.

  

Common nuclear fission technologies, including nuclear pulse rocket engines, nuclear rockets, nuclear thermal rocket and nuclear stamping rockets to nuclear thermal rocket, for example, the size of its land-based nuclear power plant reactor structure than the much smaller, more uranium-235 purity requirements high, reaching more than 90%, at the request of the high specific impulse engine core temperature will reach about 3000K, require excellent high temperature properties of materials.

  

Research and test new IT technologies and new products and new technology and new materials, new equipment, things are difficult, design is the most important part, especially in the overall design, technical solutions, technical route, technical process, technical and economic particularly significant. The overall design is defective, technology there are loopholes in the program, will be a major technical route deviation, but also directly related to the success of research trials. so, any time, under any circumstances, a good grasp of the overall control of design, technical design, is essential. otherwise, a done deal, it is difficult save. aerospace technology research and product development is true.

  

3, high-performance nuclear rocket

Nuclear rocket nuclear fission and fusion energy can rocket rocket two categories. Nuclear fission and fusion produce heat, radiation and shock waves and other large amounts of energy, but here they are contemplated for use as a thermal energy rocket.

Uranium and other heavy elements, under certain conditions, will split their nuclei, called nuclear fission reaction. The atomic bomb is the result of nuclear fission reactions. Nuclear fission reaction to release energy, is a million times more chemical rocket propellant combustion energy. Therefore, nuclear fission energy is a high-performance rocket rockets. Since it requires much less propellant than chemical rockets can, so to its own weight is much lighter than chemical rockets energy. For the same quality of the rocket, the rocket payload of nuclear fission energy is much greater than the chemical energy of the rocket. Just nuclear fission energy rocket is still in the works. 

Use of nuclear fission energy as the energy of the rocket, called the atomic rockets. It is to make hydrogen or other inert gas working fluid through the reactor, the hydrogen after the heating temperature quickly rose to 2000 ℃, and then into the nozzle, high-speed spray to produce thrust. 

A vision plan is to use liquid hydrogen working fluid, in operation, the liquid hydrogen tank in the liquid hydrogen pump is withdrawn through the catheter and the engine cooling jacket and liquid hydrogen into hydrogen gas, hydrogen gas turbine-driven, locally expansion. Then by nuclear fission reactors, nuclear fission reactions absorb heat released, a sharp rise in temperature, and finally into the nozzle, the rapid expansion of high-speed spray. Calculations show that the amount of atomic payload rockets, rocket high chemical energy than 5-8 times.

Hydrogen and other light elements, under certain conditions, their nuclei convergent synthesis of new heavy nuclei, and release a lot of energy, called nuclear fusion reaction, also called thermonuclear reaction. 

Using energy generated by the fusion reaction for energy rocket, called fusion energy rocket or nuclear thermal rockets. But it is also not only take advantage of controlled nuclear fusion reaction to manufacture hydrogen bombs, rockets and controlled nuclear fusion reaction needs still studying it.

Of course there are various research and development of rocket technology and technical solutions to try.

It is envisaged that the rocket deuterium, an isotope of hydrogen with deuterium nuclear fusion reaction of helium nuclei, protons and neutrons, and release huge amounts of energy, just polymerized ionized helium to temperatures up to 100 million degrees the plasma, and then nozzle expansion, high-speed ejection, the exhaust speed of up to 15,000 km / sec, atomic energy is 1800 times the rocket, the rocket is the chemical energy of 3700 times.

 

Nuclear rocket engine fuel as an energy source, with liquid hydrogen, liquid helium, liquid ammonia working fluid. Nuclear rocket engine mounted in the thrust chamber of the reactor, cooling nozzle, the working fluid delivery and control systems and other components. In a nuclear reactor, nuclear energy into heat to heat the working fluid, the working fluid is heated after expansion nozzle to accelerate to the speed of 6500 ~ 11,000 m / sec from the discharge orifice to produce thrust. Nuclear rocket engine specific impulse (250 to 1000 seconds) long life, but the technology is complex, apply only to long-term spacecraft. This engine due to nuclear radiation protection, exhaust pollution, reactor control and efficient heat exchanger design and other issues not resolved, is still in the midst of trials. Nuclear rocket technology is cutting-edge aerospace science technology, centralized many professional and technical sciences and aerospace, nuclear physics, nuclear chemistry, materials science, the long term future ___-- wide width. The United States, Russia and Europe, China, India, Japan, Britain, Brazil and other countries in this regard have studies, in particular the United States and Russia led the way, impressive. Of course, at this stage of nuclear rocket technology, technology development there are still many difficulties. Fully formed, still to be. But humanity marching to the universe, nuclear reactor applications is essential.

Insulation, 9 energy. Any space exploration are inseparable from the energy battery is a new super hybrid energy storage device, the asymmetric lead-acid batteries and supercapacitors in the same compound within the system - and the so-called inside, no additional separate electronic control unit, this is an optimal combination. The traditional lead-acid battery PbO2 monomer is a positive electrode plate and a negative electrode plate spongy Pb composition, not a super cell. : Silicon solar cells, multi-compound thin film solar cells, multi-layer polymer-modified electrode solar cells, nano-crystalline solar cells, batteries and super class. For example, the solar aircraft .10. To protect the health and life safety and security systems. Lysophosphatidic acid LPA is a growth factor-like lipid mediators, the researchers found that this substance can on apoptosis after radiation injury and animal cells was inhibited. Stable lysophosphatidic acid analogs having the hematopoietic system and gastrointestinal tract caused by acute radiation sickness protection, knockout experiments show that lysophosphatidic acid receptors is an important foundation for the protection of radiation injury. In addition to work under high pressure, the astronauts face a number of health threats, including motion sickness, bacterial infections, blindness space, as well as psychological problems, including toxic dust. In the weightless environment of space, the astronaut's body will be like in preadolescents, as the emergence of various changes.

Plantar molt

After the environment to adapt to zero gravity, the astronaut's body will be some strange changes. Weightlessness cause fluid flow around the main flow torso and head, causing the astronauts facial swelling and inflammation, such as nasal congestion. During long-term stay in space

 

Bone and muscle loss

Most people weightlessness caused by the impact may be known bone and muscle degeneration. In addition, the calcium bones become very fragile and prone to fracture, which is why some of the astronauts after landing need on a stretcher.

Space Blindness

Space Blindness refers astronaut decreased vision.

Solar storms and radiation is one of the biggest challenges facing the long-term space flight. Since losing the protection of Earth's magnetic field, astronauts suffer far more than normal levels of radiation. The cumulative amount of radiation exposure in low earth orbit them exceeded by workers close to nuclear reactors, thereby increasing the risk of cancer.

Prolonged space flight can cause a series of psychological problems, including depression or mood swings, vulnerability, anxiety and fear, as well as other sequelae. We are familiar with the biology of the Earth, the Earth biochemistry, biophysics, after all, the Earth is very different astrophysics, celestial chemistry, biophysics and astrophysics, biochemistry and other celestial bodies. Therefore, you must be familiar with and adapt to these differences and changes.

 

Osteoporosis and its complications ranked first in the space of disease risk.

  

Long-term health risks associated with flying Topics

  

The degree of influence long-term biological effects of radiation in human flight can withstand the radiation and the maximum limit of accumulated radiation on physiology, pathology and genetics.

 

Physiological effects of weightlessness including: long-term bone loss and a return flight after the maximum extent and severity of the continued deterioration of other pathological problems induced by the; maximum flexibility and severity of possible long-term Flight Center in vascular function.

 

Long-term risk of disease due to the high risk of flight stress, microbial variation, decreased immune function, leading to infections

 

Radiation hazards and protection

However, space technology itself is integrated with the use of the most advanced technology, its challenging technical reserves and periodic demanding

 

With the continuous development of science and technology, space agencies plan a manned landing on the moon and Mars, space exploration emergency medicine current concern.

 

Space sickness

  

In the weightless environment of space, in the weightless environment of space, surgery may be extremely difficult and risky.

  

Robot surgeons

 

Space disease in three days after entering the space started to ease, although individual astronauts might subsequently relapse. January 2015 NASA declared working on a fast, anti-nausea and nasal sprays. In addition, due to the zero-gravity environment, and anti-nausea drugs can only be administered by injection or transdermal patches manner.

        

Manned spaceflight in the 21st century is the era of interplanetary flight, aerospace medicine is closely watched era is the era of China's manned space flourish. Only the central issue, and grasp the opportunity to open up a new world of human survival and development.

 

Various emergency contingency measures in special circumstances. Invisible accident risk prevention. Enhancing drugs and other screening methods immunity aerospace medicine and tissue engineering a microgravity environment. Drug mixture of APS, ginseng polysaccharides, Ganoderma lucidum polysaccharides, polysaccharides and Lentinan, from other compounds. Drug development space syndrome drug, chemical structure modification will be an important part.

These issues are very sensitive, cutting-edge technology is a major difficulty landing on Mars. Countries in the world, especially the world's major space powers in the country strategies and technical research, the results of all kinds continue to emerge. United States, Russia, China, Europe, India, Japan and other countries is different. United States, Russia extraordinary strength. Many patented technology and health, and most belong to the top-secret technology. Especially in aerospace engineering and technological achievements is different from the general scientific literature, practical, commercial, industrial great, especially the performance of patents, know-how, technical drawings, engineering design and other aspects. Present Mars and return safely to Earth, the first manned, significance, everything is hard in the beginning, especially the first person to land on Mars This Mars for Human Sciences Research Mars, the moon, the earth, the solar system and the universe, life and other significant. Its far greater than the value of direct investments and business interests.

 

In addition, it is the development of new materials, suitable for deep space operations universe, life, and other detection, wider field.

Many aerospace materials, continuous research and development of materials are key areas of aerospace development, including material rocket, the spacecraft materials, the suit materials, radiation materials, materials and equipment, instruments, materials and so on biochemistry.

W Fiber Reinforced with nickel-based, iron-based alloys as well as SiC, TiB2, Si3N4 and BN particle reinforced metal matrix composites

High temperature service conditions require the development of ceramic and carbon-based composite materials, etc., not in this eleven Cheung said.

  

Fuel storage

  

In order to survive in space, people need many things: food, oxygen, shelter, and, perhaps most importantly, fuel. The initial quality Mars mission somewhere around 80 percent of the space launch humans will be propellant. The fuel amount of storage space is very difficult.

  

This difference in low Earth orbit cause liquid hydrogen and liquid oxygen - rocket fuel - vaporization.

Hydrogen is particularly likely to leak out, resulting in a loss of about 4% per month.

  

When you want to get people to Mars speed to minimize exposure to weightlessness and space radiation hazards

 

Mars

 

Landings on the Martian surface, they realized that they reached the limit. The rapid expansion of the thin Martian atmosphere can not be very large parachute, such as those that will need to be large enough to slow down, carry human spacecraft.

Therefore, the parachute strong mass ratio, high temperature resistance, Bing shot performance and other aspects of textile materials used have special requirements, in order to make a parachute can be used in rockets, missiles, Yu arrows spacecraft and other spacecraft recovery, it is necessary to improve the canopy heat resistance, a high melting point polymeric fiber fabric used, the metal fabric, ceramic fiber fabrics, and other devices.

  

Super rigid parachute to help slow the landing vehicle.

Spacecraft entered the Martian atmosphere at 24,000 km / h. Even after slowing parachute or inflatable, it will be very

  

Once we have the protection of the Earth magnetic field, the solar radiation will accumulate in the body, a huge explosion threw the spacecraft may potentially lethal doses of radiation astronauts.

  

In addition to radiation, the biggest challenge is manned trip to Mars microgravity, as previously described.

  

The moon is sterile. Mars is another case entirely.

 

With dust treatment measures.

  

Arid Martian environment to create a super-tiny dust particles flying around the Earth for billions of years.

 

Apollo moon dust encountered. Ultra-sharp and abrasive lunar dust was named something that can clog the basic functions of mechanical damage. High chloride salt, which can cause thyroid problems in people.

 

*** Mars geological structure and geological structure of the moon, water on Mars geology, geology of the Moon is very important, because he, like the Earth's geology is related to many important issues. Water, the first element of life, air, temperature, and complex geological formations are geological structure. Cosmic geology research methods, mainly through a variety of detection equipment equipped with a space probe, celestial observations of atmospheric composition, composition and distribution of temperature, pressure, wind speed, vertical structure, composition of the solar wind, the water, the surface topography and Zoning, topsoil the composition and characteristics of the component surface of the rock, type and distribution, stratigraphic sequence, structural system and the internal shell structure.

 

Mars internal situation only rely on its surface condition of large amounts of data and related information inferred. It is generally believed that the core radius of 1700 km of high-density material composition; outsourcing a layer of lava, it is denser than the Earth's mantle some; outermost layer is a thin crust. Compared to other terrestrial planets, the lower the density of Mars, which indicates that the Martian core of iron (magnesium and iron sulfide) with may contain more sulfur. Like Mercury and the Moon, Mars and lack active plate movement; there is no indication that the crust of Mars occurred can cause translational events like the Earth like so many of folded mountains. Since there is no lateral movement in the earth's crust under the giant hot zone relative to the ground in a stationary state. Slight stress coupled with the ground, resulting in Tharis bumps and huge volcano. For the geological structure of Mars is very important, which is why repeated explorations and studies of Martian geological reasons.

Crust

The outermost layer of the crust.

Crustal thickness obtained, the original thickness of the low north 40 km south plateau 70 kilometers thick, an average of 50 kilometers, at least 80 km Tharsis plateau and the Antarctic Plateau, and in the impact basin is thin, as only about 10 kilometers Greece plains.

  

Canyon of Mars there are two categories: outflow channels (outflow channel) and tree valley (valley network). The former is very large, it can be 100 km wide, over 2000 km long, streamlined, mainly in the younger Northern Hemisphere, such as the plain around Tyre Chris Canyon and Canyon jam.

 

In addition, the volcanic activity sometimes lava formation lava channels (lava channel); crustal stress generated by fissures, faults, forming numerous parallel extending grooves (fossa), such as around the huge Tharsis volcanic plateau radially distributed numerous grooves, which can again lead to volcanic activity.

  

Presumably, Mars has an iron as the main component of the nucleus, and contains sulfur, magnesium and other light elements, the nuclear share of Mars, the Earth should be relatively small. The outer core is covered with a thick layer of magnesium-rich silicate mantle, the surface of rocky crust. The density of Earth-like planets Mars is the lowest, only 3.93g / cc.

Lunar core

The average density of the Moon is 3.3464 g / cc, the solar system satellites second highest (after Aiou). However, there are few clues mean lunar core is small, only about 350 km radius or less [2]. The core of the moon is only about 20% the size of the moon, the moon's interior has a solid, iron-rich core diameter of about 240 kilometers (150 miles); in addition there is a liquid core, mainly composed of iron outer core, about 330 km in diameter (205 miles), and for the first time compared with the core of the Earth, considered as the earth's outer core, like sulfur and oxygen may have lighter elements [4].

 

Chemical elements on the lunar surface constituted in accordance with its abundance as follows: oxygen (O), silicon (Si), iron (Fe), magnesium (Mg), calcium (Ca), aluminum (Al), manganese (Mn), titanium ( Ti). The most abundant is oxygen, silicon and iron. The oxygen content is estimated to be 42% (by weight). Carbon (C) and nitrogen (N) only traces seem to exist only in trace amounts deposited in the solar wind brings.

Moon geological history is an important event in recent global magma ocean crystallization. The specific depth is not clear, but some studies have shown that at least a depth of about 500 kilometers or more.

 

Lunar landscape

Lunar landscape can be described as impact craters and ejecta, some volcanoes, hills, lava-filled depressions.

  

Regolith

TABLE bear the asteroid and comets billions of years of bombardment. Over time, the impact of these processes have already broken into fine-grained surface rock debris, called regolith. Young mare area, regolith thickness of about 2 meters, while the oldest dated land, regolith thickness of up to 20 meters. Through the analysis of lunar soil components, in particular the isotopic composition changes can determine the period of solar activity. Solar wind gases possible future lunar base is useful because oxygen, hydrogen (water), carbon and nitrogen is not only essential to life, but also may be useful for fuel production. Lunar soil constituents may also be as a future source of energy.

Here, repeatedly stressed that the geological structure and geological structure of celestial bodies, the Earth, Moon, Mars, or that this human existence and development of biological life forms is very important, especially in a series of data Martian geological structure geological structure is directly related to human landing Mars and the successful transformation of Mars or not. for example, water, liquid water, water, oxygen, synthesis, must not be taken lightly.

Mars landing 10 Technology

 

Aerospace Science and space science and technology major innovation of the most critical of sophisticated technology R & D project

  

[

"1" rocket propulsion technology ion fusion nuclear pulse propulsion rocket powered high-speed heavy rocket technology, space nuclear reactors spacecraft] brought big problems reflected in the nuclear reaction, nuclear radiation on spacecraft launch, control, brakes and other impact.

In particular, for the future of nuclear power spacecraft, the need to solve the nuclear reactor design, manufacture, control, cooling, radiation shielding, exhaust pollution, high thermoelectric conversion efficiency and a series of technical problems.

In particular, nuclear reactors produce radiation on astronauts' health will pose a great threat, which requires the spacecraft to be nuclear radiation shielding to ensure astronaut and ship the goods from radiation and heat from the reactor influence, but this will greatly increase the weight of the detector.

Space nuclear process applications, nuclear reaction decay is not a problem, but in a vacuum, ultra-low temperature environment, the nuclear reaction materials, energy transport materials have very high demands.

Space facing the reality of a nuclear reactor cooling cooling problems. To prevent problems with the reactor, "Washington" aircraft carrier to take four heavy protective measures for the radiation enclosed in the warship. These four measures are: the fuel itself, fuel storage pressure vessel, reactor shell and the hull. US Navy fuel all metal fuel, designed to take the impact resistance of the war, does not release fission product can withstand more than 50 times the gravity of the impact load; product of nuclear fission reactor fuel will never enter loop cooling water. The third layer of protection is specially designed and manufactured the reactor shell. The fourth layer is a very strong anti-impact combat ship, the reactor is arranged in the center of the ship, very safe. Engage in a reactor can only be loaded up to the aircraft, so as to drive the motor, and then drive the propeller. That is the core advantage of the heat generated by the heated gas flow, high temperature high pressure gas discharge backward, thereby generating thrust.

  

.

  

After installation AMPS1000 type nuclear power plant, a nuclear fuel assembly: He is a core member of the nuclear fuel chain reaction. Usually made into uranium dioxide, of which only a few percent uranium-235, and most of it is not directly involved in the nuclear fission of uranium 238. The uranium dioxide sintered into cylindrical pieces, into a stainless steel or a zirconium alloy do metal tubes called fuel rods or the original, then the number of fuel rods loaded metal cylinder in an orderly composition of the fuel assembly, and finally put a lot of vertical distribution of fuel assemblies in the reactor.

 

Nuclear reactor pressure vessel is a housing for containing nuclear fuel and reactor internals, for producing high-quality high-strength steel is made to withstand the pressure of dozens MPa. Import and export of the coolant in the pressure vessel.

 

The top of the pressure vessel closure, and can be used to accommodate the fixed control rod drive mechanism, pressure vessel head has a semi-circular, flat-topped.

 

Roof bolt: used to connect the locking pressure vessel head, so that the cylinder to form a completely sealed container.

  

Neutron Source: Plug in nuclear reactors can provide sufficient neutron, nuclear fuel ignition, to start to enhance the role of nuclear reactors and nuclear power. Neutron source generally composed of radium, polonium, beryllium, antimony production. Neutron source and neutron fission reactors are fast neutron, can not cause fission of uranium 235, in order to slow down, we need to moderator ---- full of pure water in a nuclear reactor. Aircraft carriers, submarines use nuclear reactor control has proven more successful.

 

Rod: has a strong ability to absorb neutrons, driven by the control rod drive mechanism, can move up and down in a nuclear reactor control rods within the nuclear fuel used to start, shut down the nuclear reactor, and maintain, regulate reactor power. Hafnium control rods in general, silver, indium, cadmium and other metals production.

 

Control rod drive mechanism: He is the executive body of nuclear reactors operating system and security protection systems, in strict accordance with requirements of the system or its operator control rod drives do move up and down in a nuclear reactor, nuclear reactor for power control. In a crisis situation, you also can quickly control rods fully inserted into the reactor in order to achieve the purpose of the emergency shutdown

 

Upper and lower support plate: used to secure the fuel assembly. High temperature and pressure inside the reactor is filled with pure water (so called pressurized water reactors), on the one hand he was passing through a nuclear reactor core, cooling the nuclear fuel, to act as a coolant, on the other hand it accumulates in the pressure vessel in play moderated neutrons role, acting as moderator.

  

Water quality monitoring sampling system:

Adding chemical system: under normal circumstances, for adding hydrazine, hydrogen, pH control agents to the primary coolant system, the main purpose is to remove and reduce coolant oxygen, high oxygen water suppression equipment wall corrosion (usually at a high temperature oxygen with hydrogen, especially at low temperatures during startup of a nuclear reactor with added hydrazine oxygen); when the nuclear reactor control rods stuck for some reason can not shutdown time by the the system can inject the nuclear reactor neutron absorber (such as boric acid solution), emergency shutdown, in order to ensure the safety of nuclear submarines.

 

Water system: a loop inside the water will be reduced at work, such as water sampling and analysis, equipment leaks, because the shutdown process cooling water and reduction of thermal expansion and contraction.

 

Equipment cooling water system:

Pressure safety systems: pressure reactor primary coolant system may change rapidly for some reason, the need for effective control. And in severe burn nuclear fuel rods, resulting in a core melt accident, it is necessary to promptly increase the pressure. Turn the regulator measures the electric, heating and cooling water. If necessary, also temporary startup booster pump.

 

Residual Heat Removal System: reactor scram may be due to an accident, such as when the primary coolant system of the steam generator heat exchanger tube is damaged, it must be urgently closed reactors.

 

Safety Injection System: The main components of this system is the high-pressure injection pump.

 

Radioactive waste treatment systems:

 

Decontamination Systems: for the removal of radioactive deposits equipment, valves, pipes and accessories, and other surfaces.

 

Europe, the United States and Russia and other countries related to aircraft carriers, submarines, icebreakers, nuclear-powered research aircraft, there are lots of achievements use of nuclear energy, it is worth analysis. However, nuclear reactor technology, rocket ships and the former are very different, therefore, requires special attention and innovative research. Must adopt a new new design techniques, otherwise, fall into the stereotype, it will avail, nothing even cause harm Aerospace.

Aerospace Science and space science and technology major innovation of the most critical of sophisticated technology R & D project

-------------------------------------------------- -------------

Aerospace Science Space Science and Technology on behalf of the world's most cutting-edge leader in high technology, materials, mechatronics, information and communication, energy, biomedical, marine, aviation aerospace, microelectronics, computer, automation, intelligent biochips, use of nuclear energy, light mechanical and electrical integration, astrophysics, celestial chemistry, astrophysics and so a series of geological science and technology. Especially after the moon landing, the further development of mankind to Mars and other planets into the powerful offensive, the world's major powers eager to Daxian hand of God, increase investment, vigorously develop new sophisticated technology projects for space to space. Satellite, space station, the new spacecraft, the new space suits, the new radiation protection materials, intelligent materials, new manufacturing technology, communications technology, computer technology, detector technology, rover, rover technology, biomedical technology, and so one after another, is expected to greater breakthroughs and leaps. For example, rocket technology, spacecraft design, large power spacecraft, spacesuits design improvements, radiation multifunctional composite materials, life health care technology and space medicine, prevention against microgravity microgravity applicable drugs, tracking control technology, landing and return technology. Mars lander and returned safely to Earth as a top priority. Secondly, Mars, the Moon base and the use of transforming Mars, the Moon and other development will follow. Whether the former or the latter, are the modern aerospace science, space science basic research, applied basic research and applied research in the major cutting-edge technology. These major cutting-edge technology research and innovation, not only for human landing on Mars and the safe return of great significance, but for the entire space science, impact immeasurable universe sciences, earth sciences and human life. Here the most critical of the most important research projects of several sophisticated technology research and development as well as its core technology brief. Limit non-scientific techniques include non-technical limits of technology, the key lies in technology research and development of technology maturity, advanced technology, innovative, practical, reliable, practical application, business value and investment costs, and not simply like the idea mature technology achievements, difficult to put into things. This is the high-tech research and development, testing, prototype, test application testing, until the outcome of industrialization. Especially in aerospace technology, advanced, novelty, practicality, reliability, economy, maturity, commercial value and so on. For technical and research purely science fiction and the like may be irrelevant depth, but not as aerospace engineering and technology practice. Otherwise, Mars will become a dream fantasy, and even into settling crashed out of danger.

 

Regardless of the moon or Mars, many technical difficulties, especially a human landing on Mars and return safely to Earth, technical difficulties mainly in the following aspects. (Transformation of Mars and the Moon and other planets and detect other livable technology more complex and difficult, at this stage it is difficult to achieve and therefore not discussed in detail in this study). In fact, Mars will be the safe return of a full set of technology, space science, aerospace crucial scientific research development, its significance is not confined to Mars simply a return to scientific value, great commercial value, can not be measure.

1. Powered rocket, the spacecraft overall structural design not be too complex large, otherwise, the safety factor to reduce the risk of failure accidents. Fusion rocket engine main problem to be solved is the high-temperature materials and fuel ignition chamber (reaction chamber temperatures of up to tens of millions of supreme billion degrees), fissile class rocket engine whose essence is the miniaturization of nuclear reactors, and placed on the rocket. Nuclear rocket engine fuel as an energy source, with liquid hydrogen, liquid helium, liquid ammonia working fluid. Nuclear rocket engine mounted in the thrust chamber of the reactor, cooling nozzle, the working fluid delivery and control systems and other components. This engine due to nuclear radiation protection, exhaust pollution, reactor control and efficient heat exchanger design and other issues unresolved. Electrothermal rocket engine utilizing heat energy (resistance heating or electric arc heating) working medium (hydrogen, amines, hydrazine ), vaporized; nozzle expansion accelerated after discharged from the spout to generate thrust. Static rocket engine working fluid (mercury, cesium, hydrogen, etc.) from the tank enter the ionization chamber is formed thrust ionized into a plasma jet. Electric rocket engines with a high specific impulse (700-2500 sec), extremely long life (can be repeated thousands of times a starter, a total of up to thousands of hours of work). But the thrust of less than 100N. This engine is only available for spacecraft attitude control, station-keeping and the like. One nuclear - power rocket design is as follows: Firstly, the reactor heats water to make it into steam, and then the high-speed steam ejected, push the rocket. Nuclear rocket using hydrogen as working substance may be a better solution, it is one of the most commonly used liquid hydrogen rocket fuel rocket carrying liquid hydrogen virtually no technical difficulties. Heating hydrogen nuclear reactor, as long as it eventually reaches or exceeds current jet velocity hydrogen rocket engine jet speed, the same weight of the rocket will be able to work longer, it can accelerate the Rockets faster. Here there are only two problems: First, the final weight includes the weight of the rocket in nuclear reactors, so it must be as light as possible. Ultra-small nuclear reactor has been able to achieve. Furthermore, if used in outer space, we can not consider the problem of radioactive residues, simply to just one proton hydrogen nuclei are less likely to produce induced radioactivity, thus shielding layer can be made thinner, injected hydrogen gas can flow directly through the reactor core, it is not easy to solve, and that is how to get back at high speed heated gas is ejected.

  

Rocket engine with a nuclear fission reactor, based on the heating liquid hydrogen propellant, rather than igniting flammable propellant

High-speed heavy rocket is a major cutting-edge technology. After all, space flight and aircraft carriers, submarines, nuclear reactors differ greatly from the one hand, the use of traditional fuels, on the one hand can be nuclear reactor technology. From the control, for security reasons, the use of nuclear power rocket technology, safe and reliable overriding indicators. Nuclear atomic energy in line with the norms and rules of outer space. For the immature fetal abdominal hatchery technology, and resolutely reject use. This is the most significant development of nuclear-powered rocket principle.

Nuclear-powered spaceship for Use of nuclear power are three kinds:

The first method: no water or air space such media can not be used propeller must use jet approach. Reactor nuclear fission or fusion to produce a lot of heat, we will propellant (such as liquid hydrogen) injection, the rapid expansion of the propellant will be heated and then discharged from the engine speed tail thrust. This method is most readily available.

The second method: nuclear reactor will have a lot of fast-moving ions, these energetic particles moving very fast, so you can use a magnetic field to control their ejection direction. This principle ion rocket similar to the tail of the rocket ejected from the high-speed mobile ions, so that the recoil movement of a rocket. The advantage of this approach is to promote the unusually large ratio, without carrying any medium, continued strong. Ion engine, which is commonly referred to as "electric rocket", the principle is not complicated, the propellant is ionized particles,

Plasma Engine

Electromagnetic acceleration, high-speed spray. From the development trend, the US research scope covers almost all types of electric thrusters, but mainly to the development of ion engines, NASA in which to play the most active intake technology and preparedness plans. "

The third method: the use of nuclear explosions. It is a bold and crazy way, no longer is the use of a controlled nuclear reaction, but to use nuclear explosions to drive the ship, this is not an engine, and it is called a nuclear pulse rocket. This spacecraft will carry a lot of low-yield atomic bombs out one behind, and then detonated, followed by a spacecraft propulsion installation disk, absorbing the blast pushing the spacecraft forward. This was in 1955 to Orion (Project Orion) name of the project, originally planned to bring two thousand atomic bombs, Orion later fetal nuclear thermal rocket. Its principle is mounted on a small rocket reactor, the reactor utilizing thermal energy generated by the propellant is heated to a high temperature, high pressure and high temperature of the propellant from the high-speed spray nozzle, a tremendous impetus.

  

Common nuclear fission technologies, including nuclear pulse rocket engines, nuclear rockets, nuclear thermal rocket and nuclear stamping rockets to nuclear thermal rocket, for example, the size of its land-based nuclear power plant reactor structure than the much smaller, more uranium-235 purity requirements high, reaching more than 90%, at the request of the high specific impulse engine core temperature will reach about 3000K, require excellent high temperature properties of materials.

  

Research and test new IT technologies and new products and new technology and new materials, new equipment, things are difficult, design is the most important part, especially in the overall design, technical solutions, technical route, technical process, technical and economic particularly significant. The overall design is defective, technology there are loopholes in the program, will be a major technical route deviation, but also directly related to the success of research trials. so, any time, under any circumstances, a good grasp of the overall control of design, technical design, is essential. otherwise, a done deal, it is difficult save. aerospace technology research and product development is true.

  

3, high-performance nuclear rocket

Nuclear rocket nuclear fission and fusion energy can rocket rocket two categories. Nuclear fission and fusion produce heat, radiation and shock waves and other large amounts of energy, but here they are contemplated for use as a thermal energy rocket.

Uranium and other heavy elements, under certain conditions, will split their nuclei, called nuclear fission reaction. The atomic bomb is the result of nuclear fission reactions. Nuclear fission reaction to release energy, is a million times more chemical rocket propellant combustion energy. Therefore, nuclear fission energy is a high-performance rocket rockets. Since it requires much less propellant than chemical rockets can, so to its own weight is much lighter than chemical rockets energy. For the same quality of the rocket, the rocket payload of nuclear fission energy is much greater than the chemical energy of the rocket. Just nuclear fission energy rocket is still in the works. 

Use of nuclear fission energy as the energy of the rocket, called the atomic rockets. It is to make hydrogen or other inert gas working fluid through the reactor, the hydrogen after the heating temperature quickly rose to 2000 ℃, and then into the nozzle, high-speed spray to produce thrust. 

A vision plan is to use liquid hydrogen working fluid, in operation, the liquid hydrogen tank in the liquid hydrogen pump is withdrawn through the catheter and the engine cooling jacket and liquid hydrogen into hydrogen gas, hydrogen gas turbine-driven, locally expansion. Then by nuclear fission reactors, nuclear fission reactions absorb heat released, a sharp rise in temperature, and finally into the nozzle, the rapid expansion of high-speed spray. Calculations show that the amount of atomic payload rockets, rocket high chemical energy than 5-8 times.

Hydrogen and other light elements, under certain conditions, their nuclei convergent synthesis of new heavy nuclei, and release a lot of energy, called nuclear fusion reaction, also called thermonuclear reaction. 

Using energy generated by the fusion reaction for energy rocket, called fusion energy rocket or nuclear thermal rockets. But it is also not only take advantage of controlled nuclear fusion reaction to manufacture hydrogen bombs, rockets and controlled nuclear fusion reaction needs still studying it.

Of course there are various research and development of rocket technology and technical solutions to try.

It is envisaged that the rocket deuterium, an isotope of hydrogen with deuterium nuclear fusion reaction of helium nuclei, protons and neutrons, and release huge amounts of energy, just polymerized ionized helium to temperatures up to 100 million degrees the plasma, and then nozzle expansion, high-speed ejection, the exhaust speed of up to 15,000 km / sec, atomic energy is 1800 times the rocket, the rocket is the chemical energy of 3700 times.

 

Nuclear rocket engine fuel as an energy source, with liquid hydrogen, liquid helium, liquid ammonia working fluid. Nuclear rocket engine mounted in the thrust chamber of the reactor, cooling nozzle, the working fluid delivery and control systems and other components. In a nuclear reactor, nuclear energy into heat to heat the working fluid, the working fluid is heated after expansion nozzle to accelerate to the speed of 6500 ~ 11,000 m / sec from the discharge orifice to produce thrust. Nuclear rocket engine specific impulse (250 to 1000 seconds) long life, but the technology is complex, apply only to long-term spacecraft. This engine due to nuclear radiation protection, exhaust pollution, reactor control and efficient heat exchanger design and other issues not resolved, is still in the midst of trials. Nuclear rocket technology is cutting-edge aerospace science technology, centralized many professional and technical sciences and aerospace, nuclear physics, nuclear chemistry, materials science, the long term future ___-- wide width. The United States, Russia and Europe, China, India, Japan, Britain, Brazil and other countries in this regard have studies, in particular the United States and Russia led the way, impressive. Of course, at this stage of nuclear rocket technology, technology development there are still many difficulties. Fully formed, still to be. But humanity marching to the universe, nuclear reactor applications is essential.

2. radiation. Space radiation is one of the greatest threats to the safety of the astronauts, including X-rays, γ-rays, cosmic rays and high-speed solar particles. Better than aluminum protective effect of high polymer composite materials.

3. Air. Perhaps the oxygen needed to rely on oxidation-reduction reaction of hydrogen and ilmenite production of water, followed by water electrolysis to generate oxygen. Mars oxygen necessary for survival but also from the decomposition of water, electrolytically separating water molecules of oxygen and hydrogen, this oxygen equipment has been successfully used in the International Space Station. Oxygen is released into the air to sustain life, the hydrogen system into the water system.

4. The issue of food waste recycling. At present, the International Space Station on the use of dehumidifiers, sucked moisture in the air to be purified, and then changed back to drinkable water. The astronauts' urine and sweat recycling. 5. water. The spacecraft and the space station on purification system also makes urine and other liquids can be purified utilization. 6. microgravity. In microgravity or weightlessness long-term space travel, if protective measures shall not be treated, the astronauts will be muscle atrophy, bone softening health. 7. contact. 8. Insulation, 9 energy. Any space exploration are inseparable from the energy battery is a new super hybrid energy storage device, the asymmetric lead-acid batteries and supercapacitors in the same compound within the system - and the so-called inside, no additional separate electronic control unit, this is an optimal combination. The traditional lead-acid battery PbO2 monomer is a positive electrode plate and a negative electrode plate spongy Pb composition, not a super cell. : Silicon solar cells, multi-compound thin film solar cells, multi-layer polymer-modified electrode solar cells, nano-crystalline solar cells, batteries and super class. For example, the solar aircraft .10. To protect the health and life safety and security systems. Lysophosphatidic acid LPA is a growth factor-like lipid mediators, the researchers found that this substance can on apoptosis after radiation injury and animal cells was inhibited. Stable lysophosphatidic acid analogs having the hematopoietic system and gastrointestinal tract caused by acute radiation sickness protection, knockout experiments show that lysophosphatidic acid receptors is an important foundation for the protection of radiation injury. In addition to work under high pressure, the astronauts face a number of health threats, including motion sickness, bacterial infections, blindness space, as well as psychological problems, including toxic dust. In the weightless environment of space, the astronaut's body will be like in preadolescents, as the emergence of various changes.

Plantar molt

After the environment to adapt to zero gravity, the astronaut's body will be some strange changes. Weightlessness cause fluid flow around the main flow torso and head, causing the astronauts facial swelling and inflammation, such as nasal congestion. During long-term stay in space

 

Bone and muscle loss

Most people weightlessness caused by the impact may be known bone and muscle degeneration. In addition, the calcium bones become very fragile and prone to fracture, which is why some of the astronauts after landing need on a stretcher.

Space Blindness

Space Blindness refers astronaut decreased vision.

Solar storms and radiation is one of the biggest challenges facing the long-term space flight. Since losing the protection of Earth's magnetic field, astronauts suffer far more than normal levels of radiation. The cumulative amount of radiation exposure in low earth orbit them exceeded by workers close to nuclear reactors, thereby increasing the risk of cancer.

Prolonged space flight can cause a series of psychological problems, including depression or mood swings, vulnerability, anxiety and fear, as well as other sequelae. We are familiar with the biology of the Earth, the Earth biochemistry, biophysics, after all, the Earth is very different astrophysics, celestial chemistry, biophysics and astrophysics, biochemistry and other celestial bodies. Therefore, you must be familiar with and adapt to these differences and changes.

 

Osteoporosis and its complications ranked first in the space of disease risk.

  

Long-term health risks associated with flying Topics

  

The degree of influence long-term biological effects of radiation in human flight can withstand the radiation and the maximum limit of accumulated radiation on physiology, pathology and genetics.

 

Physiological effects of weightlessness including: long-term bone loss and a return flight after the maximum extent and severity of the continued deterioration of other pathological problems induced by the; maximum flexibility and severity of possible long-term Flight Center in vascular function.

 

Long-term risk of disease due to the high risk of flight stress, microbial variation, decreased immune function, leading to infections

 

Radiation hazards and protection

    

1) radiation medicine, biology and pathway effects Features

  

Radiation protection for interplanetary flight, since the lack of protective effect of Earth's magnetic field, and by the irradiation time is longer, the possibility of increased radiation hazard.

With the continuous development of science and technology, space agencies plan a manned landing on the moon and Mars, space exploration emergency medicine current concern.

 

Space sickness

  

In the weightless environment of space, in the weightless environment of space, surgery may be extremely difficult and risky.

  

Robot surgeons

 

Space disease in three days after entering the space started to ease, although individual astronauts might subsequently relapse. January 2015 NASA declared working on a fast, anti-nausea and nasal sprays. In addition, due to the zero-gravity environment, and anti-nausea drugs can only be administered by injection or transdermal patches manner.

        

Manned spaceflight in the 21st century is the era of interplanetary flight, aerospace medicine is closely watched era is the era of China's manned space flourish. Only the central issue, and grasp the opportunity to open up a new world of human survival and development.

 

Various emergency contingency measures in special circumstances. Invisible accident risk prevention. Enhancing drugs and other screening methods immunity aerospace medicine and tissue engineering a microgravity environment. Drug mixture of APS, ginseng polysaccharides, Ganoderma lucidum polysaccharides, polysaccharides and Lentinan, from other compounds. Drug development space syndrome drug, chemical structure modification will be an important part.

These issues are very sensitive, cutting-edge technology is a major difficulty landing on Mars. Countries in the world, especially the world's major space powers in the country strategies and technical research, the results of all kinds continue to emerge. United States, Russia, China, Europe, India, Japan and other countries is different. United States, Russia extraordinary strength. Many patented technology and health, and most belong to the top-secret technology. Especially in aerospace engineering and technological achievements is different from the general scientific literature, practical, commercial, industrial great, especially the performance of patents, know-how, technical drawings, engineering design and other aspects. Present Mars and return safely to Earth, the first manned, significance, everything is hard in the beginning, especially the first person to land on Mars This Mars for Human Sciences Research Mars, the moon, the earth, the solar system and the universe, life and other significant. Its far greater than the value of direct investments and business interests.

 

In addition, it is the development of new materials, suitable for deep space operations universe, life, and other detection, wider field.

Many aerospace materials, continuous research and development of materials are key areas of aerospace development, including material rocket, the spacecraft materials, the suit materials, radiation materials, materials and equipment, instruments, materials and so on biochemistry.

High temperature service conditions require the development of ceramic and carbon-based composite materials, etc., not in this eleven Cheung said.

  

Fuel storage

  

In order to survive in space, people need many things: food, oxygen, shelter, and, perhaps most importantly, fuel. The initial quality Mars mission somewhere around 80 percent of the space launch humans will be propellant. The fuel amount of storage space is very difficult.

  

This difference in low Earth orbit cause liquid hydrogen and liquid oxygen - rocket fuel - vaporization.

Hydrogen is particularly likely to leak out, resulting in a loss of about 4% per month.

  

When you want to get people to Mars speed to minimize exposure to weightlessness and space radiation hazards

 

Mars

 

Landings on the Martian surface, they realized that they reached the limit. The rapid expansion of the thin Martian atmosphere can not be very large parachute, such as those that will need to be large enough to slow down, carry human spacecraft.

Therefore, the parachute strong mass ratio, high temperature resistance, Bing shot performance and other aspects of textile materials used have special requirements, in order to make a parachute can be used in rockets, missiles, Yu arrows spacecraft and other spacecraft recovery, it is necessary to improve the canopy heat resistance, a high melting point polymeric fiber fabric used, the metal fabric, ceramic fiber fabrics, and other devices.

  

Super rigid parachute to help slow the landing vehicle.

Spacecraft entered the Martian atmosphere at 24,000 km / h. Even after slowing parachute or inflatable, it will be very

  

Once we have the protection of the Earth magnetic field, the solar radiation will accumulate in the body, a huge explosion threw the spacecraft may potentially lethal doses of radiation astronauts.

  

In addition to radiation, the biggest challenge is manned trip to Mars microgravity, as previously described.

  

The moon is sterile. Mars is another case entirely.

*** Mars geological structure and geological structure of the moon, water on Mars geology, geology of the Moon is very important, because he, like the Earth's geology is related to many important issues. Water, the first element of life, air, temperature, and complex geological formations are geological structure. Cosmic geology research methods, mainly through a variety of detection equipment equipped with a space probe, celestial observations of atmospheric composition, composition and distribution of temperature, pressure, wind speed, vertical structure, composition of the solar wind, the water, the surface topography and Zoning, topsoil the composition and characteristics of the component surface of the rock, type and distribution, stratigraphic sequence, structural system and the internal shell structure.

 

Mars internal situation only rely on its surface condition of large amounts of data and related information inferred. It is generally believed that the core radius of 1700 km of high-density material composition; outsourcing a layer of lava, it is denser than the Earth's mantle some; outermost layer is a thin crust. Compared to other terrestrial planets, the lower the density of Mars, which indicates that the Martian core of iron (magnesium and iron sulfide) with may contain more sulfur. Like Mercury and the Moon, Mars and lack active plate movement; there is no indication that the crust of Mars occurred can cause translational events like the Earth like so many of folded mountains. Since there is no lateral movement in the earth's crust under the giant hot zone relative to the ground in a stationary state. Slight stress coupled with the ground, resulting in Tharis bumps and huge volcano. For the geological structure of Mars is very important, which is why repeated explorations and studies of Martian geological reasons.

Crust

The outermost layer of the crust.

Crustal thickness obtained, the original thickness of the low north 40 km south plateau 70 kilometers thick, an average of 50 kilometers, at least 80 km Tharsis plateau and the Antarctic Plateau, and in the impact basin is thin, as only about 10 kilometers Greece plains.

  

Canyon of Mars there are two categories: outflow channels (outflow channel) and tree valley (valley network). The former is very large, it can be 100 km wide, over 2000 km long, streamlined, mainly in the younger Northern Hemisphere, such as the plain around Tyre Chris Canyon and Canyon jam.

 

In addition, the volcanic activity sometimes lava formation lava channels (lava channel); crustal stress generated by fissures, faults, forming numerous parallel extending grooves (fossa), such as around the huge Tharsis volcanic plateau radially distributed numerous grooves, which can again lead to volcanic activity.

  

Presumably, Mars has an iron as the main component of the nucleus, and contains sulfur, magnesium and other light elements, the nuclear share of Mars, the Earth should be relatively small. The outer core is covered with a thick layer of magnesium-rich silicate mantle, the surface of rocky crust. The density of Earth-like planets Mars is the lowest, only 3.93g / cc.

Lunar core

The average density of the Moon is 3.3464 g / cc, the solar system satellites second highest (after Aiou). However, there are few clues mean lunar core is small, only about 350 km radius or less [2]. The core of the moon is only about 20% the size of the moon, the moon's interior has a solid, iron-rich core diameter of about 240 kilometers (150 miles); in addition there is a liquid core, mainly composed of iron outer core, about 330 km in diameter (205 miles), and for the first time compared with the core of the Earth, considered as the earth's outer core, like sulfur and oxygen may have lighter elements [4].

 

Chemical elements on the lunar surface constituted in accordance with its abundance as follows: oxygen (O), silicon (Si), iron (Fe), magnesium (Mg), calcium (Ca), aluminum (Al), manganese (Mn), titanium ( Ti). The most abundant is oxygen, silicon and iron. The oxygen content is estimated to be 42% (by weight). Carbon (C) and nitrogen (N) only traces seem to exist only in trace amounts deposited in the solar wind brings.

Moon geological history is an important event in recent global magma ocean crystallization. The specific depth is not clear, but some studies have shown that at least a depth of about 500 kilometers or more.

 

Lunar landscape

Lunar landscape can be described as impact craters and ejecta, some volcanoes, hills, lava-filled depressions.

  

Regolith

TABLE bear the asteroid and comets billions of years of bombardment. Over time, the impact of these processes have already broken into fine-grained surface rock debris, called regolith. Young mare area, regolith thickness of about 2 meters, while the oldest dated land, regolith thickness of up to 20 meters. Through the analysis of lunar soil components, in particular the isotopic composition changes can determine the period of solar activity. Solar wind gases possible future lunar base is useful because oxygen, hydrogen (water), carbon and nitrogen is not only essential to life, but also may be useful for fuel production. Lunar soil constituents may also be as a future source of energy.

Here, repeatedly stressed that the geological structure and geological structure of celestial bodies, the Earth, Moon, Mars, or that this human existence and development of biological life forms is very important, especially in a series of data Martian geological structure geological structure is directly related to human landing Mars and the successful transformation of Mars or not. for example, water, liquid water, water, oxygen, synthesis, must not be taken lightly.

Mars landing 10 Technology

 

Aerospace Science and space science and technology major innovation of the most critical of sophisticated technology R & D project

  

[

"1" rocket propulsion technology ion fusion nuclear pulse propulsion rocket powered high-speed heavy rocket technology, space nuclear reactors spacecraft] brought big problems reflected in the nuclear reaction, nuclear radiation on spacecraft launch, control, brakes and other impact.

In particular, for the future of nuclear power spacecraft, the need to solve the nuclear reactor design, manufacture, control, cooling, radiation shielding, exhaust pollution, high thermoelectric conversion efficiency and a series of technical problems.

In particular, nuclear reactors produce radiation on astronauts' health will pose a great threat, which requires the spacecraft to be nuclear radiation shielding to ensure astronaut and ship the goods from radiation and heat from the reactor influence, but this will greatly increase the weight of the detector.

Space nuclear process applications, nuclear reaction decay is not a problem, but in a vacuum, ultra-low temperature environment, the nuclear reaction materials, energy transport materials have very high demands.

Space facing the reality of a nuclear reactor cooling cooling problems. To prevent problems with the reactor, "Washington" aircraft carrier to take four heavy protective measures for the radiation enclosed in the warship. These four measures are: the fuel itself, fuel storage pressure vessel, reactor shell and the hull. US Navy fuel all metal fuel, designed to take the impact resistance of the war, does not release fission product can withstand more than 50 times the gravity of the impact load; product of nuclear fission reactor fuel will never enter loop cooling water. The third layer of protection is specially designed and manufactured the reactor shell. The fourth layer is a very strong anti-impact combat ship, the reactor is arranged in the center of the ship, very safe. Engage in a reactor can only be loaded up to the aircraft, so as to drive the motor, and then drive the propeller. That is the core advantage of the heat generated by the heated gas flow, high temperature high pressure gas discharge backward, thereby generating thrust.

  

.

  

After installation AMPS1000 type nuclear power plant, a nuclear fuel assembly: He is a core member of the nuclear fuel chain reaction. Usually made into uranium dioxide, of which only a few percent uranium-235, and most of it is not directly involved in the nuclear fission of uranium 238. The uranium dioxide sintered into cylindrical pieces, into a stainless steel or a zirconium alloy do metal tubes called fuel rods or the original, then the number of fuel rods loaded metal cylinder in an orderly composition of the fuel assembly, and finally put a lot of vertical distribution of fuel assemblies in the reactor.

 

Nuclear reactor pressure vessel is a housing for containing nuclear fuel and reactor internals, for producing high-quality high-strength steel is made to withstand the pressure of dozens MPa. Import and export of the coolant in the pressure vessel.

 

The top of the pressure vessel closure, and can be used to accommodate the fixed control rod drive mechanism, pressure vessel head has a semi-circular, flat-topped.

 

Roof bolt: used to connect the locking pressure vessel head, so that the cylinder to form a completely sealed container.

  

Neutron Source: Plug in nuclear reactors can provide sufficient neutron, nuclear fuel ignition, to start to enhance the role of nuclear reactors and nuclear power. Neutron source generally composed of radium, polonium, beryllium, antimony production. Neutron source and neutron fission reactors are fast neutron, can not cause fission of uranium 235, in order to slow down, we need to moderator ---- full of pure water in a nuclear reactor. Aircraft carriers, submarines use nuclear reactor control has proven more successful.

 

Rod: has a strong ability to absorb neutrons, driven by the control rod drive mechanism, can move up and down in a nuclear reactor control rods within the nuclear fuel used to start, shut down the nuclear reactor, and maintain, regulate reactor power. Hafnium control rods in general, silver, indium, cadmium and other metals production.

 

Control rod drive mechanism: He is the executive body of nuclear reactors operating system and security protection systems, in strict accordance with requirements of the system or its operator control rod drives do move up and down in a nuclear reactor, nuclear reactor for power control. In a crisis situation, you also can quickly control rods fully inserted into the reactor in order to achieve the purpose of the emergency shutdown

 

Upper and lower support plate: used to secure the fuel assembly. High temperature and pressure inside the reactor is filled with pure water (so called pressurized water reactors), on the one hand he was passing through a nuclear reactor core, cooling the nuclear fuel, to act as a coolant, on the other hand it accumulates in the pressure vessel in play moderated neutrons role, acting as moderator.

  

Water quality monitoring sampling system:

Adding chemical system: under normal circumstances, for adding hydrazine, hydrogen, pH control agents to the primary coolant system, the main purpose is to remove and reduce coolant oxygen, high oxygen water suppression equipment wall corrosion (usually at a high temperature oxygen with hydrogen, especially at low temperatures during startup of a nuclear reactor with added hydrazine oxygen); when the nuclear reactor control rods stuck for some reason can not shutdown time by the the system can inject the nuclear reactor neutron absorber (such as boric acid solution), emergency shutdown, in order to ensure the safety of nuclear submarines.

 

Water system: a loop inside the water will be reduced at work, such as water sampling and analysis, equipment leaks, because the shutdown process cooling water and reduction of thermal expansion and contraction.

 

Equipment cooling water system:

Pressure safety systems: pressure reactor primary coolant system may change rapidly for some reason, the need for effective control. And in severe burn nuclear fuel rods, resulting in a core melt accident, it is necessary to promptly increase the pressure. Turn the regulator measures the electric, heating and cooling water. If necessary, also temporary startup booster pump.

 

Residual Heat Removal System: reactor scram may be due to an accident, such as when the primary coolant system of the steam generator heat exchanger tube is damaged, it must be urgently closed reactors.

 

Safety Injection System: The main components of this system is the high-pressure injection pump.

 

Radioactive waste treatment systems:

 

Decontamination Systems: for the removal of radioactive deposits equipment, valves, pipes and accessories, and other surfaces.

 

Europe, the United States and Russia and other countries related to aircraft carriers, submarines, icebreakers, nuclear-powered research aircraft, there are lots of achievements use of nuclear energy, it is worth analysis. However, nuclear reactor technology, rocket ships and the former are very different, therefore, requires special attention and innovative research. Must adopt a new new design techniques, otherwise, fall into the stereotype, it will avail, nothing even cause harm Aerospace.

The SS Comboyne was designed by John Wright and built by his son Ernest Wright at the Wright Shipyards in Tuncurry to the order of Allen Taylor and Co. Ltd. John Wright died on 28th May 1910, shortly after construction commenced. She was launched at Tuncurry on 16th June 1911 by Mabel Wright, Ernest’s wife.

She was a twin screw steamer with a wooden single deck with 2 masts and an elliptical stern. She was especially designed for the shallow bar trade.

Engines Fitted

In late June she was towed by the steamer Tuncurry to Sydney to be fitted with engines by Chapman and Co., Druitt-street. “The machinery was installed by Chapman and Co., Ltd. Engines 11in x 22in, stroke 16in, boiler 12ft 6in x 10ft, hatch 36ft x 13ft. Electric light has been fitted throughout, and she has a steam windlass, McFarlane's patent winches, and all the latest appliances for the expeditious handling of heavy cargo. The steamer is for the Camden Haven trade, and is specially adapted for the carriage of passengers, timber, butter, and fish. Designed specially for bar-harbour work, she will carry at least 230 tons on the light draft of 7ft, and must prove a great boon to the trade.” The Sydney Morning Herald 7th November 1911

She underwent trials in Sydney and undertook her maiden voyage to Camden Haven on 6th September 1911.

 

Hits rocks at Port Kembla and sinks

Just 12 months later she struck the end of the eastern breakwater at Port Kembla and foundered. reported on the event. "She left Sydney on the night of 6th September Saturday night to deliver a cargo of turpentine piles for the new low level jetty in course of construction at Port Kembla. Everything went well till entering the port at about 3 o'clock on Sunday morning [7th September 1912], when the vessel struck the end of the eastern breakwater. Captain Lucey ordered the crew to leave the ship in the lifeboat. When the steamer took her final plunge into 40ft of water, the captain commenced a swim of a quarter of a mile to the shore in the darkness. “The water was bitterly cold, and before he had gone a great distance the captain was attacked with cramps, and it was with the greatest difficulty that he reached the rocks in the vicinity of the Port Kembla Company's jetty, in an exhausted condition. The only article of clothing he had on was a pair of trousers.

The party in the boat made for the Electrolytic Company's works, where they were received by the night watchman, and allowed to dry their clothes in front of the furnaces. At daylight they repaired to the Port Kembla Hotel, where they were accommodated, and remained throughout the day. The major portion of the crew left by this evening's train for Sydney.” The Sydney Morning Herald - Monday 9 September 1912

 

A few weeks later in late September it was reported that the Comboyne had been re-floated and would be towed back to Sydney by the tug Hero and that extensive repairs would be required.

 

A Gruesome Find.

The Comboyne again made headlines in early September 1915 when the steamer was coming up the Camden Haven River and the action of the propeller swirled up the head of a man. The Ballarat Courier 22nd September 1915 reported "Investigations by police discovered a body, which was fastened by a rope to a ship's anchor-weighing at least a half a hundredweight. Further scrutiny showed that the head, which has been identified as that of William Purcell, who is believed to have lived at one time at Hunter's Hill, Sydney, had been smashed in."

 

Total loss near Kiama

Eight years later she foundered again – on this occasion off Bass Point near Kiama. The Sydney Morning Herald 28th September 1920 reported: “The steamer Comboyne, when off Bass Point, near Kiama, early on Saturday morning [27 Sept 1920], in a fog struck a submerged obstruction and sank. The members of the crew took to the boats and were later picked up by the steamer Kiama and convoyed to Kiama, whence they proceeded to Sydney by train.

The Comboyne, bound for Wollongong with a full cargo of timber, was in the charge of Captain Woods. Shortly after midnight a thick fog banked up, but as the master knew the coast and the vessel was standing well off from the shore she proceeded on her way. At about 3 o'clock on Saturday morning the Comboyne had passed Kiama, and was abreast of Bass Point, steaming well over a mile off shore, when a slight bump was felt. Almost immediately the alarm was given from below the deck that the vessel was leaking.

The pumps were manned, and an inspection of the ship was ordered. The water, however, commenced to pour into the vessel so rapidly that the pumps were quite inadequate to cope with it and an examination was made impossible. The master then ordered the boats to be got ready, and attempted to head the Comboyne for the nearest spot where he could beach her. His efforts, however, were unavailing. The vessel, in striking the obstruction, had apparently torn part of her bottom out, and through the holes the water poured in to such an extent that she quickly took a big list and commenced to settle down.

The order was then given to abandon the ship, and in two boats the crew left her. Within a minute or so, and within eight minutes of the accident, the Comboyne heeled over and sank.

The occupants of the boats cruised about until the fog lifted, when they commenced to make for the nearest safe landing. They had not gone far, however, when the steamer Kiama hove in sight. The Kiama, noticing the distress signals, stood by and took them aboard, landing them at Kiama.

All the possessions of the crew were lost with the ship. The Comboyne was a well-known coaster. Owned by Allen Taylor and Co., Ltd., she was a twin-screw steamer of 281 tons, built especially for the timber trade at Tuncurry, N.S.W., in 1911."

KITGUM, Uganda -- When 1st Lt. Victoria Lynn Watson deployed to Uganda for Natural Fire 10, she never imagined using her labor and delivery nursing skills during the exercise.

 

But when a Ugandan woman, Linda, arrived in labor at Pajimo medical clinic, where the Army Reserve's 7225th Medical Support Unit was partnering with East African medics to offer healthcare to the Kitgum community, Watson sprang into action.

 

She checked her watch. It was nearly 2:30 pm when medics hurried the 19-year-old expectant mother from the clinic gates where hundreds had gathered to receive care.

 

During the 10-day exercise, the medics run a daily clinic to treat upwards of 700 Ugandans a day for ailments such as arthritis, minor wounds, skin infections --and dental and optometry care. Soldiers from Uganda, Rwanda, Tanzania, Kenya and Burundi are working alongside U.S. troops on medical, dental and engineering projects in the Kitgum region. Meanwhile, each nation is also taking part in security training and a simulated disaster relief exercise.

 

While pregnancy was not a planned treatment, the Pajimo clinic staffs a midwife and Watson was eager to assist. If the U.S. Army Reserve officer were back home in Abilene, Texas, she would do the same.

 

"This is what I do. I'm a labor and delivery nurse in my civilian job," Watson said, hurrying past Ugandan families clutching medicines and awaiting dental checks, "This is what I live for."

 

Watson serves with the 7231st Medical Support Unit in Lubbock, Texas, but volunteered to augment the 7225th for Uganda.

 

Once in the clinics maternity ward, Watson and Pfc. Kendra Hinds, a U.S. Army Reserve medic from Lubbock, Texas, joined Stella, the Ugandan midwife. Stella asked the lieutenant to work with her to deliver the child.

 

Stella and her Ugandan assistant prepared the delivery room. Watson's examined the woman - nine centimeters and having contractions. Her watch read 3 p.m.

 

Hinds never helped a woman give birth. So, Watson talked her through the exam as they felt the mother's stomach to see where the baby was.

 

"You can feel the contractions," Watson said to Hines. "Her sides and belly get hard. Feel here...that's the head. It's in the right place, that's good. The baby is aligned right."

 

The midwife, Stella Betty Lamono – who goes by Stella, produced a Pinnard Horn - a wooden listening device not often seen in America that is used to hear the baby's heartbeat. Watson and Hinds took turns listening.

 

Then Stella posed a question.

 

"You are delivering," Stella said. "You should name the baby."

 

"OK, I'll name the baby," Watson said, in a light-hearted way. "How about, let's see...Gracie for a girl? Yes, I like Gracie."

 

"And a boy?" asked Stella.

 

"Okay, for a boy...Cage. I like Cage."

 

Stella translated. The mother smiled, amused despite her obvious discomfort. It was nearly 3:30 p.m., the baby was coming but the delivery team still had things to do. They tried to start an intravenous drip.

 

There was a problem, they couldn't find a vein. They spoke with the mother and found she had not eaten anything for two days.

 

"She's dehydrated, she needs something with sugar," Watson said.

 

Soldiers offered sweet powdered drink pack from their daily rations - MRE's, such as lemon-flavored ice tea and a lemon-lime electrolyte drinks.

 

Watson stirred each drink in a green plastic cup and gave it to the mother, who drank thirstily.

 

The team then found a vein for an IV, the mother tried to relax. From time to time, she would lift a pink curtain and gaze through the window into the dusty yard. Things quieted.

 

Meanwhile, her sister arranged swaddling clothes on the receiving table at the other side of the room.

 

"How many weeks is she?" Hinds asked.

 

"Thirty-eight," Stella said, confidently.

 

Ugandan midwives determine the duration of the pregnancy by feeling the stomach for the size of the baby's head versus the height of the fundus -- how high the uterus has pressed upwards into the diaphragm.

 

"This is amazing," Watson said. "In the States, doctors run a sonogram over the belly, ask for the date of the last menstrual period, and go from there. We learn the 'old school' way, but we never actually do it like Stella has."

 

Certified Ugandan midwifes attend a three-year school, Stella said, herself a midwife with seven years experience who delivers up to 28 babies each month -- often in rural clinics.

 

The contractions continued. The mother remained stoic despite the lack of any pain medicine. Sweat beaded on her face, veins throbbed along her neck. She would lay calm more moments, the moan softly and slap the nearby wall. Hinds grabbed a cloth and patted her face and held her hands through contractions.

  

"Most girls in the States would be yelling and hollering by now," Watson said.

 

Unlike in the States, the clinic had no monitors, electrical gadgetry or air conditioning. It did have clean water, sterilized equipment and a trained midwife, plus her U.S. counterparts.

 

It was around 4 p.m., when the mother groaned and slapped the wall again.

 

"She's in second stage," Watson said. "All she has to do now is push."

 

A few minutes passed, the mother began to push – Hinds held her hand and continued to comfort her. Then came a loud cry from a healthy baby boy. It was 4:30 p.m.

 

Watson wiped him down. He waved his tiny hands and stared around the room with large, alert eyes. Stella tied up the stump of the umbilical cord

 

"You delivered the baby, what name did you pick for a baby boy,” Stella said, reminding Watson.

 

“Cage," Watson replied. "But I can't name her baby. It's her baby!"

 

Hinds placed the infant into his mother's arms. The new mom smiled.

 

"What is she going to name him?" Watson asked. Stella translated. The mother answered --and Stella began to laugh.

 

"What did she say?" Watson asked.

 

"She decided she liked the name you picked," Stella said. "She named her little boy 'Cage'."

 

Outside, U.S. and East African medics were closing up for the day, handing out the final doses of vitamins and routine medications, when they learned the good news. An officer took out the records reflecting the number of people treated, changing 714 to 715, to add Cage - Kitgum's newest resident.

 

"It's pretty amazing there's a little one out here that I named and that I helped bring into this world," Watson said. "Pretty amazing."

Watson, an Army Reserve Soldier from Abilene, Texas, and deployed with the 7225th Medical Support Unit (MSU), is a labor and delivery nurse in her civilian occupation and was called upon to assist when the 19-year-old expectant mother arrived at the clinic in an advanced state of labor. The mother gave birth to a healthy, 5.5 lb. baby boy about 90 minutes later --and asked that Watson name her son. Watson named the baby "Cage." (Photo credit Maj.

Army Reserve Nurse Delivers Baby in Rural Uganda

 

By Maj.Corey Schultz, U.S. Army Reserve Command

 

KITGUM, Uganda -- When 1st Lt. Victoria Lynn Watson deployed to Uganda for Natural Fire 10, she never imagined using her labor and delivery nursing skills during the exercise.

 

But when a Ugandan woman, Linda, arrived in labor at Pajimo medical clinic, where the Army Reserve's 7225th Medical Support Unit was partnering with East African medics to offer healthcare to the Kitgum community, Watson sprang into action.

 

She checked her watch. It was nearly 2:30 pm when medics hurried the 19-year-old expectant mother from the clinic gates where hundreds had gathered to receive care.

 

During the 10-day exercise, the medics run a daily clinic to treat upwards of 700 Ugandans a day for ailments such as arthritis, minor wounds, skin infections --and dental and optometry care.
