Bacha log, in this Module we are going to see different, different Marketing Strategic
Techniques. To start with Social Marketing, now it aims to increase the acceptability of a
social idea, cause or practice among a target group. Example is campaign for prohibition of
smoking, right. Second example would be P&G, they collect or they donate, right, for every
product that we buy out of which 2 or 3 rupees is donated towards Girl Child Shiksha
Abhiyan. Isn’t it good, yes?
Next we see is Augmented Marketing, now in here it is the provision of additional customer
services and benefit built around the core and the actual products that relate to the
introduction of hi-tech services like, online computer services, etc. Herein example could be
Asian Paints, they give five years warranty on certain paints.
Direct Marketing, is a marketing strategy that interacts directly with the consumers asking
them to make a direct response. Example through catalogues selling, mail, electronic
marketing, Television shopping, etc.
Relationship Marketing, it is a process of creating, maintaining and enhancing strong value
laden relationships with customers and other stakeholders. It will go a long way in building
relationships. Example, Emirates, right, when you fly by Emirates they send a Mercedes,
right, per passenger at your residence, so if it is a family of four, you can even ask for four
Mercedes and they provide. And they pick you up from your door, that is your home till
airport. And again from your destination airport to the hotel a Mercedes service is
provided. Same, British Airways, offers special lounges with showers at 199 airports for
frequent fliers. Isn’t it amazing, yes.
Next, Services Marketing, It is applying the concepts, tools and techniques of marketing to
services. Services is any activity that one party can offer to another that is essentially

The shape of these old Tin Mine buildings is so pleasing. I guess if they were built today they would be a steel frame with some panelling bolted on to the outside and would have a prefabricated metal chimney. These techniques weren't available then, but even so I get the feeling that some effort was put into making them look pleasing. Why doesn't this happen these days? It seems all too often that when we put up a building now the drive for efficiency and cost control far outweigh any consideration for making the thing pleasing to the eye and making it enhance its' surroundings.
I'm sure these mines were pretty horrible to work in but at least these purely industrial buildings enhanced the landscape.
172 333 rushes through Bordesley Station with 2S50 Worcester Foregate Street to Whitlocks End viewed through the 'windows' of the main entrance stairwell. The station does see only one timetabled departure, in one direction, per week. That would be 2V30 13.18 Whitlocks End to Great Malvern, which would call here at 13.36, don't be late as there could be a long wait. Although it can see up to a dozen departures when Birmingham City play at home with St Andrews a shortish walk from here.

This old public toilet by the harbor appears to be used mainly by the fisherman who launch their boats nearby, but apparently someone was afraid a foreigner might wander by and not recognize the Japanese character for male, and decided a more universal symbol was also needed, just in case.

With a simple pull of the lever, these decorative figures can open and close their jaws like authentic nutcrackers!
Both of these models were built in the recent weeks leading up to Christmas. The design was pretty straightforward, but two major issues were making the faces look good, and finally getting the hats right. In fact, the green nutcracker's crown took the longest to figure out, and was finally made with hinge plates.
As mentioned in the tutorial, although these can in fact function as real nutcrackers, they're somewhat rickety and best suited for holiday decorations.

These chairs weren't part of an exhibit; they were scattered all over the courtyard and are actual seating. Every chair has a designer behind it, though. Even when everyone's too distracted by the gigantic steel Serra sculpture in front of them to notice.
Since they're just, y'know, seating, these weren't labelled or any such thing, but I believe that they are Bertoia side chairs, by Harry Bertoia, designed in 1952. The chairs are made of welded steel rods and have a powder-coat finish.
If they are not Bertoias, they are very good imitations of them. However, since this is MoMA, I'm inclined to believe that they're the real deal.
Not level track but functional. Here US Steel's Granite City Works SW1200 #1248 pokes out across Madison Av while switching the mill. A 24/7 operation, most of the railroad activity takes place within the mill or when they run to the east across IL 203 to the iron making division/slag area. It's a common occurrence but still a treat when they poke out of the western side of the property.
As the TIE-Striker is the only ship from the TIE-series with articulated solar panels so far, it was very important to me, to include that function into my MOC.
The access to change the wings position from upward to horizontal position is hidden underneath the pilot cockpit hatch.
By rotating a technic axle, the wings go up and down and will stay in any position you stop the movement.
Off course the wing still can move in its set positino when turning the TIE-Striker around. That function works best when the TIE-Striker rests on its stand, as the wings are quit heavy for the little mechanism to get moved (but it´s still possible without the stand).
All of the technic is hidden inside the tiny space between the pilot and bombardier cockpit.
The technic beam to lift the wings up and down is located right under the wings to maintain the cylindrical design of the cockpit pod.
It was a real hard chanllange to get the wings move to in the right angles and more than that to include all of the technic nearly invisible inside the pod.
I hope you like it!

Pasted from Wikipedia: Bell-Boeing V-22 Osprey
• • • • •
The Bell-Boeing V-22 Osprey is a multi-mission, military, tiltrotor aircraft with both a vertical takeoff and landing (VTOL), and short takeoff and landing (STOL) capability. It is designed to combine the functionality of a conventional helicopter with the long-range, high-speed cruise performance of a turboprop aircraft.
The V-22 originated from the U.S. Department of Defense Joint-service Vertical take-off/landing Experimental (JVX) aircraft program started in 1981. It was developed jointly by the Bell Helicopter, and Boeing Helicopters team, known as Bell Boeing, which produce the aircraft.[4] The V-22 first flew in 1989, and began years of flight testing and design alterations.
The United States Marine Corps began crew training for the Osprey in 2000, and fielded it in 2007. The Osprey's other operator, the U.S. Air Force fielded their version of the tiltrotor in 2009. Since entering service with the U.S. Marine Corps and Air Force, the Osprey has been deployed for combat operations in Iraq and Afghanistan.

Development
Early development
The failure of the Iran hostage rescue mission in 1980 demonstrated to the United States military a need[5] for "a new type of aircraft, that could not only take off and land vertically but also could carry combat troops, and do so at speed."[6] The U.S. Department of Defense began the Joint-service Vertical take-off/landing Experimental (JVX) aircraft program in 1981, under U.S. Army leadership. Later the U.S. Navy/Marine Corps took the lead.[7][8] The JVX combined requirements from the Marine Corps, Air Force, Army and Navy.[9][10] A request for proposals (RFP) was issued in December 1982 for JVX preliminary design work. Interest in the program was expressed by Aérospatiale, Bell Helicopter, Boeing Vertol, Grumman, Lockheed, and Westland. The DoD pushed for contractors to form teams. Bell partnered with Boeing Vertol. The Bell Boeing team submitted a proposal for a enlarged version of the Bell XV-15 prototype on 17 February 1983. This was the only proposal received and a preliminary design contract was awarded on 26 April 1983.[11][12]
The JVX aircraft was designated V-22 Osprey on 15 January 1985; by March that same year the first six prototypes were being produced, and Boeing Vertol was expanded to deal with the project workload.[13][14] Work has been split evenly between Bell and Boeing. Bell Helicopter manufactures and integrates the wing, nacelles, rotors, drive system, tail surfaces, and aft ramp, as well as integrates the Rolls-Royce engines and performs final assembly. Boeing Helicopters manufactures and integrates the fuselage, cockpit, avionics, and flight controls.[4][15] The USMC variant of the Osprey received the MV-22 designation and the Air Force variant received CV-22; reversed from normal procedure to prevent Marine Ospreys from having a conflicting designation with aircraft carriers (CV).[16] Full-scale development of the V-22 tilt-rotor aircraft began in 1986.[2] On 3 May 1986 the Bell-Boeing partnership was awarded a $1.714 billion contract for V-22 aircraft by the Navy, thus at this point the project had acquisition plans with all four arms of the U.S. military.[17]
The first V-22 was rolled out with significant media attention in May 1988.[18][19] However the project suffered several political blows. Firstly in the same year, the Army left the program, citing a need to focus its budget on more immediate aviation programs.[20] The project also faced considerable dialogue in the Senate, surviving two votes that both could have resulted in cancellation.[21][22] Despite the Senate's decision, the Department of Defense instructed the Navy not to spend more money on the Osprey.[23] At the same time, the Bush administration sought the cancellation of the project.[23]
Flight testing and design changes
The first of six MV-22 prototypes first flew on 19 March 1989 in the helicopter mode,[24] and on 14 September 1989 as a fixed-wing plane.[25] The third and fourth prototypes successfully completed the Osprey's first Sea Trials on the USS Wasp in December 1990.[26] However, the fourth and fifth prototypes crashed in 1991-92.[27] Flight tests were resumed in August 1993 after changes were incorporated in the prototypes.[2] From October 1992 until April 1993, Bell and Boeing redesigned the V-22 to reduce empty weight, simplify manufacture and reduce production costs. This redesigned version became the B-model.[28]
Flight testing of four full-scale development V-22s began in early 1997 when the first pre-production V-22 was delivered to the Naval Air Warfare Test Center, Naval Air Station Patuxent River, Maryland. The first EMD flight took place on 5 February 1997. The first of four low rate initial production aircraft, ordered on 28 April 1997, was delivered on 27 May 1999. Osprey number 10 completed the program's second Sea Trials, this time from the USS Saipan in January 1999.[2] During external load testing in April 1999, Boeing used a V-22 to lift and transport the M777 howitzer.[29] In 2000, Boeing announced that the V-22 would be fitted with a nose-mounted GAU-19 Gatling gun,[30] but the GAU-19 gun was later canceled.[31]
In 2000, there were two further fatal crashes, killing a total of 19 Marines, and the production was again halted while the cause of these crashes was investigated and various parts were redesigned.[32] The V-22 completed its final operational evaluation in June 2005. The evaluation was deemed successful; events included long range deployments, high altitude, desert and shipboard operations. The problems identified in various accidents had been addressed.[33]
Controversy
The V-22's development process has been long and controversial, partly due to its large cost increases.[34] When the development budget, first planned for $2.5 billion in 1986, increased to a projected $30 billion in 1988, then-Defense Secretary Dick Cheney tried to zero out its funding. He was eventually overruled by Congress.[32] As of 2008, $27 billion have been spent on the Osprey program and another $27.2 billion will be required to complete planned production numbers by the end of the program.[2]
The V-22 squadron's former commander at Marine Corps Air Station New River, Lt. Colonel Odin Lieberman, was relieved of duty in 2001 after allegations that he instructed his unit that they needed to falsify maintenance records to make the plane appear more reliable.[2][35] Three officers were later implicated in the falsification scandal.[34]
The aircraft is incapable of autorotation, and is therefore unable to land safely in helicopter mode if both engines fail. A director of the Pentagon's testing office in 2005 said that if the Osprey loses power while flying like a helicopter below 1,600 feet (490 m), emergency landings "are not likely to be survivable". But Captain Justin (Moon) McKinney, a V-22 pilot, says that this will not be a problem, "We can turn it into a plane and glide it down, just like a C-130".[31] A complete loss of power would require the failure of both engines, as a drive shaft connects the nacelles through the wing; one engine can power both proprotors.[36] While vortex ring state (VRS) contributed to a deadly V-22 accident, the aircraft is less susceptible to the condition than conventional helicopters and recovers more quickly.[5] The Marines now train new pilots in the recognition of and recovery from VRS and have instituted operational envelope limits and instrumentation to help pilots avoid VRS conditions.[32][37]
It was planned in 2000 to equip all V-22s with a nose-mounted Gatling gun, to provide "the V-22 with a strong defensive firepower capability to greatly increase the aircraft's survivability in hostile actions."[30] The nose gun project was canceled however, leading to criticism by retired Marine Corps Commandant General James L. Jones, who is not satisfied with the current V-22 armament.[31] A belly-mounted turret was later installed on some of the first V-22s sent to the War in Afghanistan in 2009.[38]
With the first combat deployment of the MV-22 in October 2007, Time Magazine ran an article condemning the aircraft as unsafe, overpriced, and completely inadequate.[31] The Marine Corps, however, responded with the assertion that much of the article's data were dated, obsolete, inaccurate, and reflected expectations that ran too high for any new field of aircraft.[39]
Recent development
On 28 September 2005, the Pentagon formally approved full-rate production for the V-22.[40] The plan is to boost production from 11 a year to between 24 and 48 a year by 2012. Of the 458 total planned, 360 are for the Marine Corps, 48 for the Navy, and 50 for the Air Force at an average cost of $110 million per aircraft, including development costs.[2] The V-22 had an incremental flyaway cost of $70 million per aircraft in 2007,[3] but the Navy hopes to shave about $10 million off that cost after a five-year production contract starts in 2008.[41]
The Bell-Boeing Joint Project Office in Amarillo, Texas will design a new integrated avionics processor to resolve electronics obsolescence issues and add new network capabilities.[42]
Design
The Osprey is the world's first production tiltrotor aircraft, with one three-bladed proprotor, turboprop engine, and transmission nacelle mounted on each wingtip. It is classified as a powered lift aircraft by the Federal Aviation Administration.[43] For takeoff and landing, it typically operates as a helicopter with the nacelles vertical (rotors horizontal). Once airborne, the nacelles rotate forward 90° in as little as 12 seconds for horizontal flight, converting the V-22 to a more fuel-efficient, higher-speed turboprop airplane. STOL rolling-takeoff and landing capability is achieved by having the nacelles tilted forward up to 45°. For compact storage and transport, the V-22's wing rotates to align, front-to-back, with the fuselage. The proprotors can also fold in a sequence taking 90 seconds.[44]
Most Osprey missions will use fixed wing flight 75 percent or more of the time, reducing wear and tear on the aircraft and reducing operational costs.[45] This fixed wing flight is higher than typical helicopter missions allowing longer range line-of-sight communications and so improved command and control.[2] Boeing has stated the V-22 design loses 10% of its vertical lift over a Tiltwing design when operating in helicopter mode because of airflow resistance due to the wings, but that the Tiltrotor design has better short takeoff and landing performance.[46]
The V-22 is equipped with a glass cockpit, which incorporates four Multi-function displays (MFDs) and one shared Central Display Unit (CDU), allowing the pilots to display a variety of images including: digimaps centered or decentered on current position, FLIR imagery, primary flight instruments, navigation (TACAN, VOR, ILS, GPS, INS), and system status. The flight director panel of the Cockpit Management System (CMS) allows for fully-coupled (aka: autopilot) functions which will take the aircraft from forward flight into a 50-foot hover with no pilot interaction other than programming the system.[47] The glass cockpit of the canceled CH-46X was derived from the V-22.[48]
The V-22 is a fly-by-wire aircraft with triple-redundant flight control systems.[49] With the nacelles pointing straight up in conversion mode at 90° the flight computers command the aircraft to fly like a helicopter, with cyclic forces being applied to a conventional swashplate at the rotor hub. With the nacelles in airplane mode (0°) the flaperons, rudder, and elevator fly the aircraft like an airplane. This is a gradual transition and occurs over the rotation range of the nacelles. The lower the nacelles, the greater effect of the airplane-mode control surfaces.[50] The nacelles can rotate past vertical to 97.5° for rearward flight.[51][52]
The Osprey can be armed with one M240 7.62x51mm NATO (.308 in caliber) or M2 .50 in caliber (12.7 mm) machine gun on the loading ramp, that can be fired rearward when the ramp is lowered. A GAU-19 three-barrel .50 in gatling gun mounted below the V-22's nose has also been studied for future upgrade.[31][53] BAE Systems developed a remotely operated turreted weapons system for the V-22,[54] which was installed on half of the first V-22s deployed to Afghanistan in 2009.[38] The 7.62 mm belly gun turret is remotely operated by a gunner inside the aircraft, who acquires targets with a separate pod using color television and forward looking infrared imagery.
U.S. Naval Air Systems Command is working on upgrades to increase the maximum speed from 250 knots (460 km/h; 290 mph) to 270 knots (500 km/h; 310 mph), increase helicopter mode altitude limit from 10,000 feet (3,000 m) to 12,000 feet (3,700 m) or 14,000 feet (4,300 m), and increase lift performance.[55]
Operational history
US Marine Corps
Marine Corps crew training on the Osprey has been conducted by VMMT-204 since March 2000. On 3 June 2005, the Marine Corps helicopter squadron Marine Medium Helicopter 263 (HMM-263), stood down to begin the process of transitioning to the MV-22 Osprey.[56] On 8 December 2005, Lieutenant General Amos, commander of the II MEF, accepted the delivery of the first fleet of MV-22s, delivered to HMM-263. The unit reactivated on 3 March 2006 as the first MV-22 squadron and was redesignated VMM-263. On 31 August 2006, VMM-162 (the former HMM-162) followed suit. On 23 March 2007, HMM-266 became Marine Medium Tiltrotor Squadron 266 (VMM-266) at Marine Corps Air Station New River, North Carolina.[57]
The Osprey has been replacing existing CH-46 Sea Knight squadrons.[58] The MV-22 reached initial operational capability (IOC) with the U.S. Marine Corps on 13 June 2007.[1] On 10 July 2007 an MV-22 Osprey landed aboard the Royal Navy aircraft carrier, HMS Illustrious in the Atlantic Ocean. This marked the first time a V-22 had landed on any non-U.S. vessel.[59]
On 13 April 2007, the U.S. Marine Corps announced that it would be sending ten V-22 aircraft to Iraq, the Osprey's first combat deployment. Marine Corps Commandant, General James Conway, indicated that over 150 Marines would accompany the Osprey set for September deployment to Al-Asad Airfield.[60][61] On 17 September 2007, ten MV-22Bs of VMM-263 left for Iraq aboard the USS Wasp. The decision to use a ship rather than use the Osprey's self-deployment capability was made because of concerns over icing during the North Atlantic portion of the trip, lack of available KC-130s for mid-air refueling, and the availability of the USS Wasp.[62]
The Osprey has provided support in Iraq, racking up some 2,000 flight hours over three months with a mission capable availability rate of 68.1% as of late-January 2008.[63] They are primarily used in Iraq's western Anbar province for routine cargo and troop movements, and also for riskier "aero-scout" missions. General David Petraeus, the top U.S. military commander in Iraq, used one to fly around Iraq on Christmas Day 2007 to visit troops.[64] Then-presidential candidate Barack Obama also flew in Ospreys during his high profile 2008 tour of Iraq.[65]
The only major problem has been obtaining the necessary spare parts to maintain the aircraft.[66] The V-22 had flown 3,000 sorties totaling 5,200 hours in Iraq as of July 2008.[67] USMC leadership expect to deploy MV-22s to Afghanistan in 2009.[66][68] General George J. Trautman, III praised the increased range of the V-22 over the legacy helicopters in Iraq and said that "it turned his battle space from the size of Texas into the size of Rhode Island."[69]
Naval Air Systems Command has devised a temporary fix for sailors to place portable heat shields under Osprey engines to prevent damage to the decks of some of the Navy's smaller amphibious ships, but they determined that a long term solution to the problem would require these decks be redesigned with heat resistant deck coatings, passive thermal barriers and changes in ship structure in order to operate V-22s and F-35Bs.[70]
A Government Accountability Office study reported that by January 2009 the Marines had 12 MV-22s operating in Iraq and they managed to successfully complete all assigned missions. The same report found that the V-22 deployments had mission capable rates averaging 57% to 68% and an overall full mission capable rate of only 6%. It also stated that the aircraft had shown weakness in situational awareness, maintenance, shipboard operations and the ability to transport troops and external cargo.[71] That study also concluded that the "deployments confirmed that the V-22’s enhanced speed and range enable personnel and internal cargo to be transported faster and farther than is possible with the legacy helicopters it is replacing".[71]
The MV-22 saw its first offensive combat mission, Operation Cobra's Anger on 4 December 2009. Ospreys assisted in inserting 1,000 Marines and 150 Afghan troops into the Now Zad Valley of Helmand Province in southern Afghanistan to disrupt communication and supply lines of the Taliban.[38] In January 2010 the MV-22 Osprey is being sent to Haiti as part of Operation Unified Response relief efforts after the earthquake there. This will be the first use the Marine V-22 in a humanitarian mission.[72]
US Air Force
The Air Force's first operational CV-22 Osprey was delivered to the 58th Special Operations Wing (58th SOW) at Kirtland Air Force Base, New Mexico on 20 March 2006. This and subsequent aircraft will become part of the 58th SOW's fleet of aircraft used for training pilots and crew members for special operations use.[73] On 16 November 2006, the Air Force officially accepted the CV-22 in a ceremony conducted at Hurlburt Field, Florida.[74]
The US Air Force's first operational deployment of the Osprey sent four CV-22s to Mali in November 2008 in support of Exercise Flintlock. The CV-22s flew nonstop from Hurlburt Field, Florida with in-flight refueling.[5] AFSOC declared that the 8th Special Operations Squadron reached Initial Operational Capability on 16 March 2009, with six of its planned nine CV-22s operational.[75]
In June 2009, CV-22s of the 8th Special Operations Squadron delivered 43,000 pounds (20,000 kg) of humanitarian supplies to remote villages in Honduras that were not accessible by conventional vehicles.[76] In November 2009, the 8th SO Squadron and its six CV-22s returned from a three-month deployment in Iraq.[77]
The first possible combat loss of an Osprey occurred on 9 April, 2010, as a CV-22 went down near Qalat, Zabul Province, Afghanistan, killing four.[78][79]
Potential operators
In 1999 the V-22 was studied for use in the United Kingdom's Royal Navy,[80] it has been raised several times as a candidate for the role of Maritime Airborne Surveillance and Control (MASC).[81]
Israel had shown interest in the purchase of MV-22s, but no order was placed.[82][83] Flightglobal reported in late 2009 that Israel has decided to wait for the CH-53K instead.[84]
The V-22 Osprey is a candidate for the Norwegian All Weather Search and Rescue Helicopter (NAWSARH) that is planned to replace the Westland Sea King Mk.43B of the Royal Norwegian Air Force in 2015.[85] The other candidates for the NAWSARH contract of 10-12 helicopters are AgustaWestland AW101 Merlin, Eurocopter EC225, NHIndustries NH90 and Sikorsky S-92.[86]
Bell Boeing has made an unsolicited offer of the V-22 for US Army medical evacuation needs.[87] However the Joint Personnel Recovery Agency issued a report that said that a common helicopter design would be needed for both combat recovery and medical evacuation and that the V-22 would not be suitable for recovery missions because of the difficulty of hoist operations and lack of self-defense capabilities.[88]
The US Navy remains a potential user of the V-22, but its role and mission with the Navy remains unclear. The latest proposal is to replace the C-2 Greyhound with the V-22 in the fleet logistics role. The V-22 would have the advantage of being able to land on and support non-carriers with rapid delivery of supplies and people between the ships of a taskforce or to ships on patrol beyond helicopter range.[89] Loren B. Thompson of the Lexington Institute has suggested V-22s for use in combat search and rescue and Marine One VIP transport, which also need replacement aircraft.[90]
Variants
• V-22A
•• Pre-production full-scale development aircraft used for flight testing. These are unofficially considered A-variants after 1993 redesign.[91]
• HV-22
•• The U.S. Navy considered an HV-22 to provide combat search and rescue, delivery and retrieval of special warfare teams along with fleet logistic support transport. However, it chose the MH-60S for this role in 1992.[92]
• SV-22
•• The proposed anti-submarine warfare Navy variant. The Navy studied the SV-22 in the 1980s to replace S-3 and SH-2 aircraft.[93]
• MV-22B
•• Basic U.S. Marine Corps transport; original requirement for 552 (now 360). The Marine Corps is the lead service in the development of the V-22 Osprey. The Marine Corps variant, the MV-22B, is an assault transport for troops, equipment and supplies, capable of operating from ships or from expeditionary airfields ashore. It is replacing the Marine Corps' CH-46E[57] and CH-53D.[94]

From 1991 to 2000 there were four significant crashes, and a total of 30 fatalities, during testing.[32] Since becoming operational in 2007, the V-22 has had one possible combat loss due to an unknown cause, no losses due to accidents, and seven other notable, but minor, incidents.
• On 11 June 1991, a mis-wired flight control system led to two minor injuries when the left nacelle struck the ground while the aircraft was hovering 15 feet (4.6 m) in the air, causing it to bounce and catch fire.[97]
• On 20 July 1992, a leaking gearbox led to a fire in the right nacelle, causing the aircraft to drop into the Potomac River in front of an audience of Congressmen and other government officials at Quantico, killing all seven on board and grounding the aircraft for 11 months.[98]
• On 8 April 2000, a V-22 loaded with Marines to simulate a rescue, attempted to land at Marana Northwest Regional Airport in Arizona, stalled when its right rotor entered vortex ring state, rolled over, crashed, and exploded, killing all 19 on board.[37]
• On 11 December 2000, after a catastrophic hydraulic leak and subsequent software instrument failure, a V-22 fell 1,600 feet (490 m) into a forest in Jacksonville, North Carolina, killing all four aboard. This caused the Marine Corps to ground their fleet of eight V-22s, the second grounding that year.[99][100]

An order from LEGO came in, so I finished the engine bay entirely. The chassis drives, steers, and the active aero mechanism is fully functional. Also, shortly after I took these pictures, I did the pneumatic tubing for the top shock absorber, and it works just as intended. I'm considering limiting the travel of the suspension so the ride height is slightly lower, which will let me pressurize the top shock even more (for proper anti-squat).
Further progress will come after a week and a half. I'll be going on a short vacation, after which I will be working hard on the Koenigsegg project and placing a few last-minute Bricklink orders. Definitely will be livestreaming the completion of the car, and I'll announce the dates and times for those next week!
This is from mid summer (I finished the car 2 days before I left for college). It gives you an idea of what can be done in 1.5 months when you're really committed to something.

With a simple pull of the lever, these decorative figures can open and close their jaws like authentic nutcrackers!
Both of these models were built in the recent weeks leading up to Christmas. The design was pretty straightforward, but two major issues were making the faces look good, and finally getting the hats right. In fact, the green nutcracker's crown took the longest to figure out, and was finally made with hinge plates.
As mentioned in the tutorial, although these can in fact function as real nutcrackers, they're somewhat rickety and best suited for holiday decorations.
Sunday mornings around my home are generally very low key and easy going. Early in the morning there's a feeling of tranquility which even seems to translate into the light that shines in through the windows. I get the same feeling from these gentle shades of coral and pink, that's why I have named this improvised, modern, and functional art quilt, "Early Sunday Morning".

By the early nineteenth century, as ways of consuming the seaside matured and diversified, there was a growing appreciation of the joys and benefits to be gained by not just being beside the sea but venturing out onto the water itself without the disadvantages and dangers associated with boats.
The West Pier was designed and engineered by Eugenius Birch to attract visitors and survive in the hostile environment of the seashore. Built in 1866, it was a simple and functional structure built out from the sea using dozens of cast iron threaded columns screwed into the seabed and strengthened by a lattice of ties and girders that provide the necessary strength to support the promenade deck whilst allowing seas to pass harmlessly underneath.
Originally the West Pier had an open deck with only six small ornamental houses of Oriental design, two toll houses, glass screens at the pier head to protect visitors from the wind and lamps, with columns decorated with entwined serpents, placed around the perimeter and lit by gas. In 1875 a central bandstand was added and in the 1880′s weather screens the full length of the pier, steamer landing stages and a large pier head pavilion were constructed.
The final building, completed in 1916, was a graceful concert hall. The result was seaside architecture at its finest, designed to attract and entertain holiday-makers with all the pomp and frippery that is the essence of the English seaside resort.
The West Pier story closely follows the changing fortunes of the English seaside holiday. It began simply as a promenade pier where visitors could enjoy the thrill of walking on water; it was the place for the Victorian middle classes to socialise and exhibit their wealth, to see and be seen, to take in the sea air and admire the panoramic views of the land. By WW1 it had evolved into a pleasure pier with a great variety of seaside entertainment both indoors and out. Throughout the twenties it was immensely popular with attractions ranging from paddle steamer excursions, daring high divers and bathing from the pier head to military bands, recitals by the pier’s resident orchestra in the Concert Hall and an all-year-round programme of plays, pantomimes and ballets in the Theatre.
During WWII, the Pier was closed and mined for security reasons and sections were dismantled to prevent enemy landings. When the mines were removed and the pier reopened, after the repair of its war wounds, it completed its evolution into a funfair pier. The Theatre was converted into a restaurant on one floor and on the other the ‘Laughter Land’ games pavilion. The Concert Hall became a tea room, and the delights of the dodgems, helter-skelter, ghost train and miniature racing track could be enjoyed by all.
The pier was shut to the public in 1975 as it was deemed unsafe. A huge storm in December 2002 resulted in the dramatic collapse of the south east corner of the Concert Hall; in March 2003 the Pavilion was destroyed in an arson attack, and in May 2003 the Concert Hall was also burnt out deliberately. 2003 was a catastrophic year for the West Pier and by December 2003, a report concluded that despite the significant damage, given the wealth of salvaged material from the pier and the considerable photographic and video archive, repair and reconstruction of the pier was still viable. Unfortunately funding was not available.
The collapsed Concert Hall, being close to the beach, became a public hazard and in 2010 was removed. However, the skeletal ruin of the pier Pavilion has become an iconic feature of Brighton’s seafront. Its unique desolate beauty makes it much discussed, wondered about and photographed. The Pier has been too dangerous to access since the fires of 2003 and cannot be maintained. Over the coming years it will be reclaimed by nature and will inevitably degenerate and decay. The Trust has no intention of removing the remains unless overwhelming safety issues arise.
In 2006, planning permission was granted to the creators of the London eye to build the i360, an observation tower. It will be sited on the root-end of the pier and will open an exciting new chapter for the West Pier. This new landmark, which will be tied in with the original pier, has now commenced construction. At 175 metres high, and with an observation pod rising to 141 metres, the i360 will be Britain's highest observation tower outside London – taller even than the London Eye. The i360 follows in the spirit of the original pier, inviting visitors to "walk on air" and gain a different perspective of the city, just as they "walked on water" in the past and viewed the city from the sea. Chairman of the Brighton West Pier Trust, which owns the site of the former pier “believes that the Brighton i360 – a 'vertical pier' – is entirely in the spirit of the original pier's history and the best option to replicate its success and ethos." The i360 will restore parts of the original pier to their former glory, including the Victorian tollbooths. Parts of the cast iron supporting structure will be reused in the new visitor centre and an exhibition will enable visitors to learn about the pier's history. The cast iron structure off shore, known as the sea island, will stay but the wreckage of the derelict pier on the beach will be removed. A proportion of ticket revenues from the i360 will also go to the West Pier Trust charity, enabling it to continue promoting the pier's unique heritage.
This part of the plan really appeals to me - in the evenings, the Brighton i360 will transform into the Sky Bar – a chic, modern and accessible venue in which to relax and enjoy a glass of champagne, wine or a cocktail while taking in the stunning night-time views. The ride will be extended to 30 minutes to allow people plenty of time to enjoy their drink!!
The changing weather over a 3 day period is reflected in the photos I took of this fascinating and haunting structure – it looks quite eerie in the fog.

The Amsterdam suburb Bijlmermeer has a rather controversial reputation. Designed by the Indonesian-born city planner Siegfried Nassuth in the 1960's, it was one of the most radical interpretations of Le Corbusier's functional city, with a strict segregation of housing, offices and recreational facilities and an equally strict segregation between roads, bicycle paths and footpaths. The Bijlmermeer was also an example of excessive egalitarianism. When one of the architects designed windows in the sidewalls, the Burma Railroad survivor Nassuth dismissed this as an extravagant privilege for those who rented the outermost flats.
Although the flats were considered an improvement upon the crammed housing of the 19th century and pre-war era, the uniformity of the Bijlmer never became popular. In 1971 the first Dutch erotic film Blue Movie juxtaposed the standardised concrete blocks of the Bijlmer with the lusts a released prisoner satisfied with lonely single women in the suburb. Nassuth had hoped that the people would liked the park-like surroundings and walk barefeet in the grass like he had done in the Javanese city of Pekalongan, but Amsterdammers opted for houses with private gardens outside the city. Consequently, the area became a haven for many immigrants in the mid 1970's. Eventually, this would be the death knell for parts of the plan. The anonymity caused by the scale of the Bijlmer and the segregation of traffic streams reinforced the lack of social cohesion. Drug addicts and dealers roamed the concrete garages that the original inhabitants found so expensive. In the 1990's the city knew no better solution than to knock down a large part of the blocks.
Enough of the original plan remains to make it a potentially interesting subject for photography. In a way, the Bijlmer looks like the old-fashioned futurism in Jacques Tati's film Playtime. I have tried it a few times, but I find it very difficult to find interesting angles and get beyond purely documentary pictures. During the day, the area has become quite successful in offering the "light, air and space" that the planners had hoped to offer. Sedateness is a difficult subject to photograph.
Pasted from Wikipedia: Bell-Boeing V-22 Osprey
• • • • •
The Bell-Boeing V-22 Osprey is a multi-mission, military, tiltrotor aircraft with both a vertical takeoff and landing (VTOL), and short takeoff and landing (STOL) capability. It is designed to combine the functionality of a conventional helicopter with the long-range, high-speed cruise performance of a turboprop aircraft.
The V-22 originated from the U.S. Department of Defense Joint-service Vertical take-off/landing Experimental (JVX) aircraft program started in 1981. It was developed jointly by the Bell Helicopter, and Boeing Helicopters team, known as Bell Boeing, which produce the aircraft.[4] The V-22 first flew in 1989, and began years of flight testing and design alterations.
The United States Marine Corps began crew training for the Osprey in 2000, and fielded it in 2007. The Osprey's other operator, the U.S. Air Force fielded their version of the tiltrotor in 2009. Since entering service with the U.S. Marine Corps and Air Force, the Osprey has been deployed for combat operations in Iraq and Afghanistan.

Development
Early development
The failure of the Iran hostage rescue mission in 1980 demonstrated to the United States military a need[5] for "a new type of aircraft, that could not only take off and land vertically but also could carry combat troops, and do so at speed."[6] The U.S. Department of Defense began the Joint-service Vertical take-off/landing Experimental (JVX) aircraft program in 1981, under U.S. Army leadership. Later the U.S. Navy/Marine Corps took the lead.[7][8] The JVX combined requirements from the Marine Corps, Air Force, Army and Navy.[9][10] A request for proposals (RFP) was issued in December 1982 for JVX preliminary design work. Interest in the program was expressed by Aérospatiale, Bell Helicopter, Boeing Vertol, Grumman, Lockheed, and Westland. The DoD pushed for contractors to form teams. Bell partnered with Boeing Vertol. The Bell Boeing team submitted a proposal for a enlarged version of the Bell XV-15 prototype on 17 February 1983. This was the only proposal received and a preliminary design contract was awarded on 26 April 1983.[11][12]
The JVX aircraft was designated V-22 Osprey on 15 January 1985; by March that same year the first six prototypes were being produced, and Boeing Vertol was expanded to deal with the project workload.[13][14] Work has been split evenly between Bell and Boeing. Bell Helicopter manufactures and integrates the wing, nacelles, rotors, drive system, tail surfaces, and aft ramp, as well as integrates the Rolls-Royce engines and performs final assembly. Boeing Helicopters manufactures and integrates the fuselage, cockpit, avionics, and flight controls.[4][15] The USMC variant of the Osprey received the MV-22 designation and the Air Force variant received CV-22; reversed from normal procedure to prevent Marine Ospreys from having a conflicting designation with aircraft carriers (CV).[16] Full-scale development of the V-22 tilt-rotor aircraft began in 1986.[2] On 3 May 1986 the Bell-Boeing partnership was awarded a $1.714 billion contract for V-22 aircraft by the Navy, thus at this point the project had acquisition plans with all four arms of the U.S. military.[17]
The first V-22 was rolled out with significant media attention in May 1988.[18][19] However the project suffered several political blows. Firstly in the same year, the Army left the program, citing a need to focus its budget on more immediate aviation programs.[20] The project also faced considerable dialogue in the Senate, surviving two votes that both could have resulted in cancellation.[21][22] Despite the Senate's decision, the Department of Defense instructed the Navy not to spend more money on the Osprey.[23] At the same time, the Bush administration sought the cancellation of the project.[23]
Flight testing and design changes
The first of six MV-22 prototypes first flew on 19 March 1989 in the helicopter mode,[24] and on 14 September 1989 as a fixed-wing plane.[25] The third and fourth prototypes successfully completed the Osprey's first Sea Trials on the USS Wasp in December 1990.[26] However, the fourth and fifth prototypes crashed in 1991-92.[27] Flight tests were resumed in August 1993 after changes were incorporated in the prototypes.[2] From October 1992 until April 1993, Bell and Boeing redesigned the V-22 to reduce empty weight, simplify manufacture and reduce production costs. This redesigned version became the B-model.[28]
Flight testing of four full-scale development V-22s began in early 1997 when the first pre-production V-22 was delivered to the Naval Air Warfare Test Center, Naval Air Station Patuxent River, Maryland. The first EMD flight took place on 5 February 1997. The first of four low rate initial production aircraft, ordered on 28 April 1997, was delivered on 27 May 1999. Osprey number 10 completed the program's second Sea Trials, this time from the USS Saipan in January 1999.[2] During external load testing in April 1999, Boeing used a V-22 to lift and transport the M777 howitzer.[29] In 2000, Boeing announced that the V-22 would be fitted with a nose-mounted GAU-19 Gatling gun,[30] but the GAU-19 gun was later canceled.[31]
In 2000, there were two further fatal crashes, killing a total of 19 Marines, and the production was again halted while the cause of these crashes was investigated and various parts were redesigned.[32] The V-22 completed its final operational evaluation in June 2005. The evaluation was deemed successful; events included long range deployments, high altitude, desert and shipboard operations. The problems identified in various accidents had been addressed.[33]
Controversy
The V-22's development process has been long and controversial, partly due to its large cost increases.[34] When the development budget, first planned for $2.5 billion in 1986, increased to a projected $30 billion in 1988, then-Defense Secretary Dick Cheney tried to zero out its funding. He was eventually overruled by Congress.[32] As of 2008, $27 billion have been spent on the Osprey program and another $27.2 billion will be required to complete planned production numbers by the end of the program.[2]
The V-22 squadron's former commander at Marine Corps Air Station New River, Lt. Colonel Odin Lieberman, was relieved of duty in 2001 after allegations that he instructed his unit that they needed to falsify maintenance records to make the plane appear more reliable.[2][35] Three officers were later implicated in the falsification scandal.[34]
The aircraft is incapable of autorotation, and is therefore unable to land safely in helicopter mode if both engines fail. A director of the Pentagon's testing office in 2005 said that if the Osprey loses power while flying like a helicopter below 1,600 feet (490 m), emergency landings "are not likely to be survivable". But Captain Justin (Moon) McKinney, a V-22 pilot, says that this will not be a problem, "We can turn it into a plane and glide it down, just like a C-130".[31] A complete loss of power would require the failure of both engines, as a drive shaft connects the nacelles through the wing; one engine can power both proprotors.[36] While vortex ring state (VRS) contributed to a deadly V-22 accident, the aircraft is less susceptible to the condition than conventional helicopters and recovers more quickly.[5] The Marines now train new pilots in the recognition of and recovery from VRS and have instituted operational envelope limits and instrumentation to help pilots avoid VRS conditions.[32][37]
It was planned in 2000 to equip all V-22s with a nose-mounted Gatling gun, to provide "the V-22 with a strong defensive firepower capability to greatly increase the aircraft's survivability in hostile actions."[30] The nose gun project was canceled however, leading to criticism by retired Marine Corps Commandant General James L. Jones, who is not satisfied with the current V-22 armament.[31] A belly-mounted turret was later installed on some of the first V-22s sent to the War in Afghanistan in 2009.[38]
With the first combat deployment of the MV-22 in October 2007, Time Magazine ran an article condemning the aircraft as unsafe, overpriced, and completely inadequate.[31] The Marine Corps, however, responded with the assertion that much of the article's data were dated, obsolete, inaccurate, and reflected expectations that ran too high for any new field of aircraft.[39]
Recent development
On 28 September 2005, the Pentagon formally approved full-rate production for the V-22.[40] The plan is to boost production from 11 a year to between 24 and 48 a year by 2012. Of the 458 total planned, 360 are for the Marine Corps, 48 for the Navy, and 50 for the Air Force at an average cost of $110 million per aircraft, including development costs.[2] The V-22 had an incremental flyaway cost of $70 million per aircraft in 2007,[3] but the Navy hopes to shave about $10 million off that cost after a five-year production contract starts in 2008.[41]
The Bell-Boeing Joint Project Office in Amarillo, Texas will design a new integrated avionics processor to resolve electronics obsolescence issues and add new network capabilities.[42]
Design
The Osprey is the world's first production tiltrotor aircraft, with one three-bladed proprotor, turboprop engine, and transmission nacelle mounted on each wingtip. It is classified as a powered lift aircraft by the Federal Aviation Administration.[43] For takeoff and landing, it typically operates as a helicopter with the nacelles vertical (rotors horizontal). Once airborne, the nacelles rotate forward 90° in as little as 12 seconds for horizontal flight, converting the V-22 to a more fuel-efficient, higher-speed turboprop airplane. STOL rolling-takeoff and landing capability is achieved by having the nacelles tilted forward up to 45°. For compact storage and transport, the V-22's wing rotates to align, front-to-back, with the fuselage. The proprotors can also fold in a sequence taking 90 seconds.[44]
Most Osprey missions will use fixed wing flight 75 percent or more of the time, reducing wear and tear on the aircraft and reducing operational costs.[45] This fixed wing flight is higher than typical helicopter missions allowing longer range line-of-sight communications and so improved command and control.[2] Boeing has stated the V-22 design loses 10% of its vertical lift over a Tiltwing design when operating in helicopter mode because of airflow resistance due to the wings, but that the Tiltrotor design has better short takeoff and landing performance.[46]
The V-22 is equipped with a glass cockpit, which incorporates four Multi-function displays (MFDs) and one shared Central Display Unit (CDU), allowing the pilots to display a variety of images including: digimaps centered or decentered on current position, FLIR imagery, primary flight instruments, navigation (TACAN, VOR, ILS, GPS, INS), and system status. The flight director panel of the Cockpit Management System (CMS) allows for fully-coupled (aka: autopilot) functions which will take the aircraft from forward flight into a 50-foot hover with no pilot interaction other than programming the system.[47] The glass cockpit of the canceled CH-46X was derived from the V-22.[48]
The V-22 is a fly-by-wire aircraft with triple-redundant flight control systems.[49] With the nacelles pointing straight up in conversion mode at 90° the flight computers command the aircraft to fly like a helicopter, with cyclic forces being applied to a conventional swashplate at the rotor hub. With the nacelles in airplane mode (0°) the flaperons, rudder, and elevator fly the aircraft like an airplane. This is a gradual transition and occurs over the rotation range of the nacelles. The lower the nacelles, the greater effect of the airplane-mode control surfaces.[50] The nacelles can rotate past vertical to 97.5° for rearward flight.[51][52]
The Osprey can be armed with one M240 7.62x51mm NATO (.308 in caliber) or M2 .50 in caliber (12.7 mm) machine gun on the loading ramp, that can be fired rearward when the ramp is lowered. A GAU-19 three-barrel .50 in gatling gun mounted below the V-22's nose has also been studied for future upgrade.[31][53] BAE Systems developed a remotely operated turreted weapons system for the V-22,[54] which was installed on half of the first V-22s deployed to Afghanistan in 2009.[38] The 7.62 mm belly gun turret is remotely operated by a gunner inside the aircraft, who acquires targets with a separate pod using color television and forward looking infrared imagery.
U.S. Naval Air Systems Command is working on upgrades to increase the maximum speed from 250 knots (460 km/h; 290 mph) to 270 knots (500 km/h; 310 mph), increase helicopter mode altitude limit from 10,000 feet (3,000 m) to 12,000 feet (3,700 m) or 14,000 feet (4,300 m), and increase lift performance.[55]
Operational history
US Marine Corps
Marine Corps crew training on the Osprey has been conducted by VMMT-204 since March 2000. On 3 June 2005, the Marine Corps helicopter squadron Marine Medium Helicopter 263 (HMM-263), stood down to begin the process of transitioning to the MV-22 Osprey.[56] On 8 December 2005, Lieutenant General Amos, commander of the II MEF, accepted the delivery of the first fleet of MV-22s, delivered to HMM-263. The unit reactivated on 3 March 2006 as the first MV-22 squadron and was redesignated VMM-263. On 31 August 2006, VMM-162 (the former HMM-162) followed suit. On 23 March 2007, HMM-266 became Marine Medium Tiltrotor Squadron 266 (VMM-266) at Marine Corps Air Station New River, North Carolina.[57]
The Osprey has been replacing existing CH-46 Sea Knight squadrons.[58] The MV-22 reached initial operational capability (IOC) with the U.S. Marine Corps on 13 June 2007.[1] On 10 July 2007 an MV-22 Osprey landed aboard the Royal Navy aircraft carrier, HMS Illustrious in the Atlantic Ocean. This marked the first time a V-22 had landed on any non-U.S. vessel.[59]
On 13 April 2007, the U.S. Marine Corps announced that it would be sending ten V-22 aircraft to Iraq, the Osprey's first combat deployment. Marine Corps Commandant, General James Conway, indicated that over 150 Marines would accompany the Osprey set for September deployment to Al-Asad Airfield.[60][61] On 17 September 2007, ten MV-22Bs of VMM-263 left for Iraq aboard the USS Wasp. The decision to use a ship rather than use the Osprey's self-deployment capability was made because of concerns over icing during the North Atlantic portion of the trip, lack of available KC-130s for mid-air refueling, and the availability of the USS Wasp.[62]
The Osprey has provided support in Iraq, racking up some 2,000 flight hours over three months with a mission capable availability rate of 68.1% as of late-January 2008.[63] They are primarily used in Iraq's western Anbar province for routine cargo and troop movements, and also for riskier "aero-scout" missions. General David Petraeus, the top U.S. military commander in Iraq, used one to fly around Iraq on Christmas Day 2007 to visit troops.[64] Then-presidential candidate Barack Obama also flew in Ospreys during his high profile 2008 tour of Iraq.[65]
The only major problem has been obtaining the necessary spare parts to maintain the aircraft.[66] The V-22 had flown 3,000 sorties totaling 5,200 hours in Iraq as of July 2008.[67] USMC leadership expect to deploy MV-22s to Afghanistan in 2009.[66][68] General George J. Trautman, III praised the increased range of the V-22 over the legacy helicopters in Iraq and said that "it turned his battle space from the size of Texas into the size of Rhode Island."[69]
Naval Air Systems Command has devised a temporary fix for sailors to place portable heat shields under Osprey engines to prevent damage to the decks of some of the Navy's smaller amphibious ships, but they determined that a long term solution to the problem would require these decks be redesigned with heat resistant deck coatings, passive thermal barriers and changes in ship structure in order to operate V-22s and F-35Bs.[70]
A Government Accountability Office study reported that by January 2009 the Marines had 12 MV-22s operating in Iraq and they managed to successfully complete all assigned missions. The same report found that the V-22 deployments had mission capable rates averaging 57% to 68% and an overall full mission capable rate of only 6%. It also stated that the aircraft had shown weakness in situational awareness, maintenance, shipboard operations and the ability to transport troops and external cargo.[71] That study also concluded that the "deployments confirmed that the V-22’s enhanced speed and range enable personnel and internal cargo to be transported faster and farther than is possible with the legacy helicopters it is replacing".[71]
The MV-22 saw its first offensive combat mission, Operation Cobra's Anger on 4 December 2009. Ospreys assisted in inserting 1,000 Marines and 150 Afghan troops into the Now Zad Valley of Helmand Province in southern Afghanistan to disrupt communication and supply lines of the Taliban.[38] In January 2010 the MV-22 Osprey is being sent to Haiti as part of Operation Unified Response relief efforts after the earthquake there. This will be the first use the Marine V-22 in a humanitarian mission.[72]
US Air Force
The Air Force's first operational CV-22 Osprey was delivered to the 58th Special Operations Wing (58th SOW) at Kirtland Air Force Base, New Mexico on 20 March 2006. This and subsequent aircraft will become part of the 58th SOW's fleet of aircraft used for training pilots and crew members for special operations use.[73] On 16 November 2006, the Air Force officially accepted the CV-22 in a ceremony conducted at Hurlburt Field, Florida.[74]
The US Air Force's first operational deployment of the Osprey sent four CV-22s to Mali in November 2008 in support of Exercise Flintlock. The CV-22s flew nonstop from Hurlburt Field, Florida with in-flight refueling.[5] AFSOC declared that the 8th Special Operations Squadron reached Initial Operational Capability on 16 March 2009, with six of its planned nine CV-22s operational.[75]
In June 2009, CV-22s of the 8th Special Operations Squadron delivered 43,000 pounds (20,000 kg) of humanitarian supplies to remote villages in Honduras that were not accessible by conventional vehicles.[76] In November 2009, the 8th SO Squadron and its six CV-22s returned from a three-month deployment in Iraq.[77]
The first possible combat loss of an Osprey occurred on 9 April, 2010, as a CV-22 went down near Qalat, Zabul Province, Afghanistan, killing four.[78][79]
Potential operators
In 1999 the V-22 was studied for use in the United Kingdom's Royal Navy,[80] it has been raised several times as a candidate for the role of Maritime Airborne Surveillance and Control (MASC).[81]
Israel had shown interest in the purchase of MV-22s, but no order was placed.[82][83] Flightglobal reported in late 2009 that Israel has decided to wait for the CH-53K instead.[84]
The V-22 Osprey is a candidate for the Norwegian All Weather Search and Rescue Helicopter (NAWSARH) that is planned to replace the Westland Sea King Mk.43B of the Royal Norwegian Air Force in 2015.[85] The other candidates for the NAWSARH contract of 10-12 helicopters are AgustaWestland AW101 Merlin, Eurocopter EC225, NHIndustries NH90 and Sikorsky S-92.[86]
Bell Boeing has made an unsolicited offer of the V-22 for US Army medical evacuation needs.[87] However the Joint Personnel Recovery Agency issued a report that said that a common helicopter design would be needed for both combat recovery and medical evacuation and that the V-22 would not be suitable for recovery missions because of the difficulty of hoist operations and lack of self-defense capabilities.[88]
The US Navy remains a potential user of the V-22, but its role and mission with the Navy remains unclear. The latest proposal is to replace the C-2 Greyhound with the V-22 in the fleet logistics role. The V-22 would have the advantage of being able to land on and support non-carriers with rapid delivery of supplies and people between the ships of a taskforce or to ships on patrol beyond helicopter range.[89] Loren B. Thompson of the Lexington Institute has suggested V-22s for use in combat search and rescue and Marine One VIP transport, which also need replacement aircraft.[90]
Variants
• V-22A
•• Pre-production full-scale development aircraft used for flight testing. These are unofficially considered A-variants after 1993 redesign.[91]
• HV-22
•• The U.S. Navy considered an HV-22 to provide combat search and rescue, delivery and retrieval of special warfare teams along with fleet logistic support transport. However, it chose the MH-60S for this role in 1992.[92]
• SV-22
•• The proposed anti-submarine warfare Navy variant. The Navy studied the SV-22 in the 1980s to replace S-3 and SH-2 aircraft.[93]
• MV-22B
•• Basic U.S. Marine Corps transport; original requirement for 552 (now 360). The Marine Corps is the lead service in the development of the V-22 Osprey. The Marine Corps variant, the MV-22B, is an assault transport for troops, equipment and supplies, capable of operating from ships or from expeditionary airfields ashore. It is replacing the Marine Corps' CH-46E[57] and CH-53D.[94]
• CV-22B
•• Air Force variant for the U.S. Special Operations Command (USSOCOM). It will conduct long-range, special operations missions, and is equipped with extra fuel tanks and terrain-following radar.[95][96]

Notable accidents
Main article: Accidents and incidents involving the V-22 Osprey
From 1991 to 2000 there were four significant crashes, and a total of 30 fatalities, during testing.[32] Since becoming operational in 2007, the V-22 has had one possible combat loss due to an unknown cause, no losses due to accidents, and seven other notable, but minor, incidents.
• On 11 June 1991, a mis-wired flight control system led to two minor injuries when the left nacelle struck the ground while the aircraft was hovering 15 feet (4.6 m) in the air, causing it to bounce and catch fire.[97]
• On 20 July 1992, a leaking gearbox led to a fire in the right nacelle, causing the aircraft to drop into the Potomac River in front of an audience of Congressmen and other government officials at Quantico, killing all seven on board and grounding the aircraft for 11 months.[98]
• On 8 April 2000, a V-22 loaded with Marines to simulate a rescue, attempted to land at Marana Northwest Regional Airport in Arizona, stalled when its right rotor entered vortex ring state, rolled over, crashed, and exploded, killing all 19 on board.[37]
• On 11 December 2000, after a catastrophic hydraulic leak and subsequent software instrument failure, a V-22 fell 1,600 feet (490 m) into a forest in Jacksonville, North Carolina, killing all four aboard. This caused the Marine Corps to ground their fleet of eight V-22s, the second grounding that year.[99][100]
