INSTRUCTIONS AVAILABLE FOR P558 SUPERDUTY - MULTIPLE CONFIGURATIONS

 

On September 24, 2015, Ford unveiled the 2017 Ford Super Duty line at the 2015 State Fair of Texas. he frame is made from 95% high strength steel and the body (like the contemporary F-150) is made from 6000 series aluminum alloy. For the first time since 1999, both the Super Duty and F-150 lines are constructed using the same cab.

 

For 2017 production, the Super Duty line shares its powertrain lineup with its 2016 predecessor: a 6.2L gasoline V8, 6.8L V10 (F-450 and above), with a 6.7L diesel V8 available in all versions. The 6.2L gasoline V8 engine remains at 385 hp but torque rises from 405 lb-ft to 430 lb-ft. Additionally, the gasoline V8 produces its max torque at over 700 rpm less than the previous 405 lb-ft engine. The 6.7L diesel engine also remains at the same 440 hp (323 kW) but torque increases from 860 lb-ft upwards to 925 lb-ft.

 

The 2020 Super Duty debuted at the 2019 Chicago Auto Show. It features a revised grille and tailgate design, new wheel options, and higher-quality interior materials for the Limited trim. A new 7.3-liter gasoline engine is available. Nicknamed "Godzilla", it makes 430 horsepower and 475 lb-ft of torque.

 

Cab configurations continue to be 2-Door Regular Cab, 4-Door Super Cab, and 4-Door Super Crew Cab, with Short Box (6' 9") and Long Box (8') bed lengths. The truck will be available in F-250, F-350, and F-450 pickup truck models, and F-350, F-450, and F-550 chassis cab models. All will be available in both 4X2 and 4X4 configurations. The F-350 will be the only model available in either Single Rear Wheel (SRW) or Dual Rear Wheel (DRW) configurations, the F-450 and F-550 will only be available in a Dual Rear Wheel (DRW) configuration, and the F-250 will only be available in a Single Rear Wheel configuration.

 

This configuration of tree limbs always seems to catch my attention when I use Riverside Walk to get to work in the morning. Where may it lead if you step through?

 

+++ DISCLAIMER +++

Nothing you see here is real, even though the conversion or the presented background story might be based historical facts. BEWARE!

  

Some background:

The P-74 "Charger" was a fighter aircraft built by Lockheed for the United States Army Air Forces (USAAF). Its configuration was unusual as it was designed as a twin boom pusher configuration, where the propeller is mounted in the rear of the fuselage, pushing the aircraft forward.

 

The P-74 entered service with the USAAF in late 1944, its conception dated back to 1939 when the U.S. Army Air Corps requested with the Circular Proposal R40C domestic manufacturers to develop high performance fighter types, allowing (even demanding) unusual configurations. Lockheed did not respond immediately and missed the chance to sign a development contract in mid-1940 until early 1941. Twenty-three proposals were submitted to R40C, and after a fist selection of ideas three companies, Vultee with the large XP-54 Swoose Goose, Curtiss with its XP-55 Ascender and Northrop's XP-56 Black Bullet were able to secure prototype contracts.

 

Vultee eventually won the competition, but all these innovative new aircraft suffered from various flaws or development delays, missing various performance goals, so that none ever entered service.

 

In the meantime, Lockheed had been working on the 1939 request in the background on a private venture basis, as it was clear that by 1944 a successor to the company's own P-38 Lightning had to be offered to the USAAC.

The new North American P-51 Mustang was also a sharp competitor, esp. for the Pacific conflict theatre where long range was needed. This role was filled out very well by the P-38, but it was a relatively large and complicated aircraft, so an alternative with a single engine was strived for. Even though jet engines already showed their potential, it was clear that the requested range for the new type could only be achieved through a piston engine.

 

This aircraft became the XP-74, originally christened “Laelaps”, following Lockheed’s tradition, after a female Greek mythological dog who never failed to catch what she was hunting. It was presented as a mock-up to USAAC officials on August 8th 1942 and immediately found sponsorship: with the disappointing results from the XP-54,55 and 56 was immediately ushered into the prototype stage. Its name, though, was rejected, and the more common name “Charger” was adopted.

 

Just like Lockheed’s successful P-38 the XP-74 Charger was designed as a twin-boom aircraft, but it was driven by only a single Packard (License-built Rolls Royce Merlin) V-1650 pusher engine in the aft part of the fuselage. The tail was mounted rearward between two mid-wing booms, with a four-bladed 12-ft propeller between them. The design also included a "ducted wing section" developed by the NACA that enabled installation of cooling radiators and intercoolers in the wing root section.

 

The advantages of a pusher design are that the view forward is unobstructed and armament can be concentrated in the nose, while a major drawback is difficulty in escaping from the aircraft in an emergency, as the pilot could get drawn into the propeller blades. Lockheed deliberated between systems that would eject the pilot, or jettison the propeller or the engine, via a system of explosive bolts. Lockheed eventually installed an early ejector seat which was driven by pressurized air, combined with a mechanism that would blow the canopy off. The system was successfully tested in summer 1943, even though skepticism remained among pilots.

 

Initial armament comprised one 20mm Hispano cannon and four 12.7mm Browning machine guns, the same as in the P-38, but two machine guns were relocated from the nose into the front ends of the tail booms because of the new aircraft’s smaller overall dimensions.

 

The first prototype was ready in October 1943, with a different engine and heavier armor fitted. The second prototype was built to this specification from the start, which would become the serial production standard, the P-74A.

The P-74A used the new V-1650-9 engine, a version of the Merlin that included Simmons automatic supercharger boost control with water injection, allowing War Emergency Power as high as 2,218 hp (1,500 kW). Another change concerned the armament: a longer weapon range was deemed necessary, so the gun armament was changed into four 20mm Hispano cannons, two of the placed in the fuselage nose and one in each tail boom front end. Each gun was supplied with 250 RPG.

 

Alternatively, a nose installment with a single 37mm cannon and two 12.7mm Browning MGs was tested on the first prototype, but this arrangement was found to be less effective than the four 20mm cannons. Another factor that turned this option down was the more complicated logistics demands for three different calibers in one aircraft.

 

The P-74A was ready for service in summer 1944, but its deployment into the Pacific region took until December – the 5th Air Force first units replaced most of its P-38 and also early P-47Ds with the P-74A.These new aircraft had their first clashes with Japanese forces in January 1945.

 

The P-74 was used in a variety of roles. It was designed as an intreceptor against bombers, but its good range and handling at all altitudes made it suitable for tasks like fighter sweeps against enemy airfields, support for U.S. ground forces and protection of sea convoys and transport routes.

While the P-74 could not out-turn the A6M Zero and most other Japanese fighters when flying below 200 mph (320 km/h), its superior speed coupled with a good rate of climb meant that it could utilize energy tactics, making multiple high-speed passes at its target. Also, its focused firepower was deadly to lightly armored Japanese warplanes.

 

Because of its late service introduction, only 305 P-74s were ever produced until the end of hostilities, and they were exclusively used in the Pacific theatre. The P-74's service record shows mixed results, but usually because of misinformation. P-74s have been described as being harder to fly than traditional, single-engined aircraft, but this was because of inadequate training in the first few months of service.

Another drawback was the ejection seat system – it worked basically well, but the tank for the pressurized air turned out to be very vulnerable to enemy fire. Several P-74s literally exploded in midair after cannon fire hits, and this poeblem could only be cured when the tank section behind the cockpit received a more rigid structure and additional armor. Anyway, the P-74 was quickly retired after WWII, as the USAAF focussed on P-47 and P-51.

The kit and its assembly:

This whif was inspired by a CG rendition of a Saab J21 in a natural metal finish and with (spurious) USAAF markings, probably a skin for a flight simulator. Anyway, I was more or less enchanted by the NMF on the Saab – I had to build one, and it would become the P-74, the only USAF fighter code that had never been used.

 

The kit is the venerable Heller Saab J21A, an “old style” design with raised panel lines. But it is still around and affordable. No big mods were made to the kit during its transition into a USAAF fighter, even though I changed some minor things:

● Main landing gear was completely exchanged through struts from an Airfix A-1 Skyraider and the wheels from a Hasegawa P-51D; thin wire was added as hydraulic tubes

● New propeller blades: instead of the three-bladed original I added four much broader blades with square tips (from a Heller P-51D) to the original spinner

● Different exhaust stubs, which actually belong to a Spitfire Merlin (Special Hobby kit)

● Underfuselage flap was slightly opened

● A pilot figure was added to the nice cockpit

● The gun barrels were replaced with hollow styrene tubes

  

Painting and markings:

NMF was certain, but the rest…? I wanted to have a colorful aircraft, and eventually settled for a machine in the Pacific theatre of operations. When I browsed for options I eventually decided to apply broad black stripes on wings and fuselage, typical 5th Air Force markings that were used e. g. on P-47Ds and P-51Ds.

 

Overall design benchmark for my aircraft is a P-47D-28 of 310th FS/58th FG. The tail would be all white, and the rudder sported red and white stripes, early war insignia. The red nose trim and the deep yellow spinner were taken over from this aircraft, too. The blue individual code number is a personal addition, as well as the nose art, which was puzzled together from a Czech 'Perdubice' Meeting MiG-21 and leftover bits from a Pacific use P-51.

 

The aircraft was basically painted with Aluminum Metallizer (Humbrol 27002) and Polished Steel Metallizer (Modelmaster), and some panels were contrasted with Aluminum (Humbrol 56).

The anti-glare panel in front of the cockpit was painted in Olive Drab (Humbrol 66), the red nose trim with Humbrol 19. The tail was painted with a mix of Humbrol 34 & 196, for a very light grey, and later dry-painted with pure white.

 

The black ID stripes as well as the red and blue rudder trim were not painted, but rather created through decal sheet material (from TL Modellbau), cut to size and shape to fit into their respective places. The tail was a PITA, but for the black stripes this turned out to be very effective and convenient - an experiment that willcertainly see more future use.

 

Cockpit interior was painted in Humbrol 226 (Cockpit Green) and Zinc Chromate Green from Model Master, the landing gear wells received a chrome yellow primer (Humbrol 225) finish.

The landing gear struts were kept in bare Aluminum.

 

For weathering the kit received a rubbing treatment with grinded graphite, which adds a dark, metallic shine and emphasizes the kit’s raised panel lines. Some dry painting with Aluminum was added, too, simulating chipped paint on the leading edges, and on the black ID stripes some dark grey shading was added.

  

A relatively simple whif, but I love how the Saab 21 looks in the unusual, shiny NMF finish - and the USAAF markings with the prominent ID stripes suit it well, even though it looks a bit like a circus attraction now?

The Citroën DS (French pronunciation: ​[si.tʁɔ.ˈɛn de ɛs]) is a front-engine, front-wheel-drive executive car manufactured and marketed by the French company Citroën from 1955 to 1975 in sedan, wagon/estate and convertible body configurations. Italian sculptor and industrial designer Flaminio Bertoni and the French aeronautical engineer André Lefèbvre styled and engineered the car. Paul Magès developed the hydropneumatic self-levelling suspension.

 

Noted for its aerodynamic, futuristic body design and innovative technology, the DS set new standards in ride quality, handling, and braking—and was the first production car equipped with disc brakes.

 

Citroën sold 1,455,746 examples, including 1,330,755 built at the manufacturer's Paris Quai André-Citroën production plant.

 

The DS came third in the 1999 Car of the Century poll recognizing the world's most influential auto designs and was named the most beautiful car of all time by Classic & Sports Car magazine

 

MODEL HISTORY

After 18 years of secret development as the successor to the Traction Avant, the DS 19 was introduced on 5 October 1955 at the Paris Motor Show. In the first 15 minutes of the show, 743 orders were taken, and orders for the first day totalled 12,000. During the 10 days of the show, the DS took in 80,000 deposits; a record that has stood for over 60 years.

 

Contemporary journalists said the DS pushed the envelope in the ride vs. handling compromise possible in a motor vehicle.

 

To a France still deep in reconstruction after the devastation of World War II, and also building its identity in the post-colonial world, the DS was a symbol of French ingenuity. The DS was distributed to many territories throughout the world.

 

It also posited the nation's relevance in the Space Age, during the global race for technology of the Cold War. Structuralist philosopher Roland Barthes, in an essay about the car, said that it looked as if it had "fallen from the sky". An American advertisement summarised this selling point: "It takes a special person to drive a special car".

 

Because they were owned by the technologically aggressive tire manufacturer Michelin, Citroën had designed their cars around the technically superior radial tire since 1948, and the DS was no exception.

 

The car featured a novel hydropneumatic suspension including an automatic leveling system and variable ground clearance, developed in-house by Paul Magès. This suspension allowed the DS to travel quickly on the poor road surfaces common in France.

 

In addition, the vehicle had power steering and a semi-automatic transmission (the transmission required no clutch pedal, but gears still had to be shifted by hand), though the shift lever controlled a powered hydraulic shift mechanism in place of a mechanical linkage, and a fibreglass roof which lowered the centre of gravity and so reduced weight transfer. Inboard front brakes (as well as independent suspension) reduced unsprung weight. Different front and rear track widths and tyre sizes reduced the unequal tyre loading, which is well known to promote understeer, typical of front-engined and front-wheel drive cars.

 

As with all French cars, the DS design was affected by the tax horsepower system, which effectively mandated very small engines. Unlike the Traction Avant predecessor, there was no top-of-range model with a powerful six-cylinder engine. Citroën had planned an air-cooled flat-6 engine for the car, but did not have the funds to put the prototype engine into production.

 

The DS placed third in the 1999 Car of the Century competition, and fifth on Automobile Magazine's "100 Coolest Cars" listing in 2005. It was also named the most beautiful car of all time by Classic & Sports Car magazine after a poll of 20 world-renowned car designers, including Giorgetto Giugiaro, Ian Callum, Roy Axe, Paul Bracq, and Leonardo Fioravanti.

 

NAME

Both the DS and its simpler sibling, the ID, used a punning name. "DS" is pronounced in French as "Déesse" (goddess); "ID" is pronounced as "Idée" (idea). An intermediate model was called the DW.

 

MOTORSPORT

The DS was successful in motorsports like rallying, where sustained speeds on poor surfaces are paramount, and won the Monte Carlo Rally in 1959. In the 1000 Lakes Rally, Pauli Toivonen drove a DS19 to victory in 1962.

 

In 1966, the DS won the Monte Carlo Rally again, with some controversy as the competitive BMC Mini-Cooper team was disqualified due to rule infractions. Ironically, Mini was involved with DS competition again two years later, when a drunk driver in a Mini in Sydney Australia crashed into the DS that was leading the 1968 London–Sydney Marathon, 98 miles from the finish line. The DS was still competitive in the grueling 1974 London-Sahara-Munich World Cup Rally, where it won over 70 other cars, only 5 of which even completed the entire event.

 

TECHNICAL INNOVATION - HYDRAULIC SYSTEMS

In conventional cars, hydraulics are only used in brakes and power steering. In the DS they were also used for the suspension, clutch and transmission. The cheaper 1957 ID19 did have manual steering and a simplified power-braking system. An engine driven pump pressurizes the closed system to 2,400 pounds per square inch.

 

At a time when few passenger vehicles had independent suspension on all wheels, the application of the hydraulic system to the car's suspension system to provide a self-levelling system was an innovative move. This suspension allowed the car to achieve sharp handling combined with very high ride quality, frequently compared to a "magic carpet".

 

The hydropneumatic suspension used was pioneered the year before, on the rear of another car from Citroën, the top of range Traction Avant 15CV-H.

 

IMPACT ON CITROEN BRAND DEVELOPMENT

The 1955 DS cemented the Citroën brand name as an automotive innovator, building on the success of the Traction Avant, which had been the world's first mass-produced unitary body front-wheel-drive car in 1934. In fact, the DS caused such a huge sensation that Citroën was apprehensive that future models would not be of the same bold standard. No clean sheet new models were introduced from 1955 to 1970.

 

The DS was a large, expensive executive car and a downward brand extension was attempted, but without result. Throughout the late 1950s and 1960s Citroën developed many new vehicles for the very large, profitable market segments between the 2CV and the DS, occupied by vehicles like the Peugeot 403, Renault 16 and Ford Cortina, but none made it into production. Either they had uneconomic build costs, or were ordinary "me too" cars, not up to the company's high standard of innovation. As Citroën was owned by Michelin from 1934 to 1974 as a sort of research laboratory, such broad experimentation was possible. Michelin after all was getting a powerful advertisement for the capabilities of the radial tire Michelin had invented, when such experimentation was successful.

 

New models based on the small, utilitarian 2CV economy car were introduced, notably the 1961 Ami. It was also designed by Flaminio Bertoni and aimed to combine Three-box styling with the chassis of the 2CV. The Ami was very successful in France, but less so on export markets. Many found the styling controversial, and the car noisy and underpowered. The Dyane, was a modernised 2CV with a hatchback, competed with the 2CV inspired Renault 4 Hatchback. All these 2 cylinder models were very small, so there remained a wide market gap to the DS range all through the 1960s.

 

In 1970, Citroën finally introduced a car to target the mid-range - the Citroën GS, which won the "European car of the Year" for 1971 and sold 2.5 million units. It combined a small 55 horsepower flat-4 air-cooled engine with Hydropneumatic suspension. The intended 106 horsepower Wankel rotary-engined version with more power did not reach full production.

 

REPLACING THE DS

The DS remained popular and competitive throughout its production run. Its peak production year was 1970. Certain design elements like the somewhat narrow cabin, column-mounted gearstick, and separate fenders began to seem a little old-fashioned in the 1970s.

 

Citroën invested enormous resources to design and launch an entirely new vehicle in 1970, the SM, which was in effect a thoroughly modernized DS, with similar length, but greater width. The manual gearbox was a modified DS unit. The front disc brakes were the same design. Axles, wheel bearings, steering knuckles, and hydraulic components were either DS parts or modified DS parts.

 

The SM had a different purpose than replacing the 15-year-old DS design however - it was meant to launch Citroën into a completely new luxury grand touring market segment. Only fitted with a costly, exotic Maserati engine, the SM was faster and much more expensive than the DS. The SM was not designed to be a practical 4-door saloon suitable as a large family car, the key market for vehicles of this type in Europe. Typically, manufacturers would introduce low-volume coupés based on parts shared with an existing saloon, not as unique models, a contemporary example being the Mercedes-Benz SLC-Class.

 

The SM's high price and limited utility of the 2+2 seating configuration, meant the SM as actually produced could not seize the mantle from the DS.

 

So, while the design funds invested would allow the DS to be replaced by two cars - a 'modern DS' and the smaller CX, it was left to the CX alone to provide Citroën's large family or executive car in the model range.

 

The last DS came off the production line on 24 April 1975 - the manufacturer had taken the elementary precaution of building up approximately eight-month's of inventory of the "break" (estate/station wagon) version of the DS, to cover the period till Autumn 1975 when the estate/station wagon version of the CX would be introduced.

 

DEVELOPMENT

The DS always maintained its size and shape, with easily removable, unstressed body panels, but certain design changes did occur. During the 20-year production life improvements were made on an ongoing basis.

ID 19 submodel to extend brand downwards (1957–69)

 

The 1955 DS19 was 65% more expensive than the car it replaced, the Citroën Traction Avant. This affected potential sales in a country still recovering economically from World War II, so a cheaper submodel, the Citroën ID, was introduced in 1957.

 

The ID shared the DS's body but was less powerful and luxurious. Although it shared the engine capacity of the DS engine (at this stage 1,911 cc), the ID provided a maximum power output of only 69 hp compared to the 75 hp claimed for the DS19. Power outputs were further differentiated in 1961 when the DS19 acquired a Weber-32 twin bodied carburettor, and the increasing availability of higher octane fuel enabled the manufacturer to increase the compression ratio from 7.5:1 to 8.5:1. A new DS19 now came with a promised 83 hp of power. The ID19 was also more traditional mechanically: it had no power steering and had conventional transmission and clutch instead of the DS's hydraulically controlled set-up. Initially the basic ID19 was sold on the French market with a price saving of more than 25% against the DS, although the differential was reduced at the end of 1961 when the manufacturer quietly withdrew the entry level ID19 "Normale" from sale. A station wagon variant, the ID Break, was introduced in 1958.

 

D SPECIAL AND D SUPER (1970–75)

The ID was replaced by the D Spécial and D Super in 1970, but these retained the lower specification position in the range. The D Super was available with the DS21 2175ccm engine and a 5 speed gearbox, and named the D Super 5.

 

SERIE 2 - NOSE REDESIGN IN 1962

In September 1962, the DS was restyled with a more aerodynamically efficient nose, better ventilation and other improvements. It retained the open two headlamp appearance, but was available with an optional set of driving lights mounted on the front fenders. All models in the range changed nose design at the same time, including the ID and station wagon models.

Series 3 - Nose redesign in 1967 with Directional headlights

 

In late 1967, for the 1968 model year, the DS and ID was again restyled, by Robert Opron, who also styled the 1970 SM and 1974 CX. This version had a more streamlined headlamp design, giving the car a notably shark-like appearance. This design had four headlights under a smooth glass canopy, and the inner set swivelled with the steering wheel. This allowed the driver to see "around" turns, especially valuable on twisting roads driven at high speed at night.

 

Behind each glass cover lens, the inboard high-beam headlamp swivels by up to 80° as the driver steers, throwing the beam along the driver's intended path rather than uselessly across the curved road. The outboard low-beam headlamps are self-leveling in response to pitching caused by acceleration and braking.

 

However, this feature was not allowed in the US at the time (see World Forum for Harmonization of Vehicle Regulations), so a version with four exposed headlights that did not swivel was made for the US market.

 

This 'turning headlight' feature was new to the market - it had only been seen before on the very rare three headlight 1935 Tatra 77A. The Tucker, which never was mass-produced, had a central headlight that turned with the steering. 45 years later, it is now a commonly available feature, even in the United States.

 

NEW GREEN HYDRAULIC FLUID

The original hydropneumatic system used a vegetable oil liquide hydraulique végétal (LHV), similar to that used in other cars at the time, but later switched to a synthetic fluid liquide hydraulique synthétique (LHS). Both of these had the disadvantage that they are hygroscopic, as is the case with most brake fluids. Disuse allows water to enter the hydraulic components causing deterioration and expensive maintenance work. The difficulty with hygroscopic hydraulic fluid was exacerbated in the DS/ID due to the extreme rise and fall in the fluid level in the reservoir, which went from nearly full to nearly empty when the suspension extended to maximum height and the six accumulators in the system filled with fluid. With every "inhalation" of fresh moisture- (and dust-) laden air, the fluid absorbed more water.

 

For the 1967 model year, Citroën introduced a new mineral oil-based fluid LHM (Liquide Hydraulique Minéral). This fluid was much less harsh on the system. LHM remained in use within Citroën until the Xantia was discontinued in 2001.

 

LHM required completely different materials for the seals. Using either fluid in the incorrect system would completely destroy the hydraulic seals very quickly. To help avoid this problem, Citroën added a bright green dye to the LHM fluid and also painted all hydraulic elements bright green. The former LHS parts were painted black.

 

All models, including the station wagon and ID, were upgraded at the same time. The hydraulic fluid changed to the technically superior LHM in all markets except the US and Canada, where the change did not take place until January 1969, due to local regulations.

 

INTERNATIONAL SALES AND PRODUCTION

The DS was primarily manufactured at the Quai André-Citroën in the Javel neighborhood of Paris, with other manufacturing facilities in the United Kingdom, South Africa, the former Yugoslavia (mostly Break Ambulances), and Australia.

 

Australia constructed their own D variant in the 1960s at Heidelberg, Victoria, identified as the ID 19 "Parisienne." Australian market cars were fitted with options as standard equipment such as the "DSpecial DeLuxe" that were not available on domestic European models.

 

Until 1965, cars were assembled at the manufacturer's Slough premises, to the west of London, using a combination of French made knock down kits and locally sourced components, some of them machined on site. A French electrical system superseded the British one on the Slough cars in 1962, giving rise to a switch to "continental style" negative earthing. After 1965 cars for the British market were imported fully assembled from the company's French plant. The British-built cars are distinguished by their leather seats, wooden (early ID19 models) one piece plastic (early DS19 models) dashboards, chromed number plate mount let into the front bumper, and (on pre-1962 cars) Lucas-made electrics. These were all right hand drive cars.

 

The DS was built and sold in South Africa from 1959 to 1975.

 

The DS was sold in Japan, but the models were built in France and left hand drive.

 

DS IN NORTH AMERICA

The DS was sold in North America from 1956 to 1972. Despite its popularity in Europe, it didn't sell well in the United States, and little better in Canada. While promoted as a luxury car, it did not have the basic features that American buyers expected to find on such a vehicle, such as an automatic transmission, air conditioning, power windows, or a powerful engine. The DS was designed specifically to address the French market, with punitive tax horsepower taxation of large engines, as well as very poor roads – it's no great mystery that it was a fish out of water when those constraints were removed.

 

Jay Leno described the sporadic supply of spare parts as a problem for 1970s era customers, based on his early experiences working at a Citroën dealer in Boston.

 

The DS was expensive, with a 115 hp (86 kW) vehicle costing $4,170 in 1969, when the price was $4,500 for a 360 hp (268 kW) Buick Electra 225 4 door sedan. For all years, 38,000 units were sold.

 

US regulations at the time also banned one of the car's more advanced features: its composite headlamps with aerodynamic covered lenses. Based on legislation that dated from 1940, all automobiles sold in the U.S. were required to have round, sealed beam headlamps that produced a meager 75,000 candlepower. The powerful quartz iodine swiveling headlamps designed for the 1968 model DS represented so many performance improvements at once that they were far beyond what the regulations could allow.[50] Even the aerodynamic headlight covers were illegal – as seen on the 1968 Jaguar E-Type. It took the lobbying muscle of Ford to point out that the government was requiring two contradictory things – safety, by ensuring that all headlights were best-of-breed circa 1940, and fuel economy through the CAFE standard – by definition, cars with poor aerodynamics are sacrificing fuel economy. Composite bulb lamps and aerodynamic covered headlights were not permitted until 1983.

 

The European lamps were legal in Canada, including the directional headlamps.

 

The hydraulic fluid change in 1967 was another brain teaser for U.S. automotive regulators at the Department of Transportation. NHTSA follows the precautionary principle, also used by the Food and Drug Administration, where new innovations are prohibited until their developers can prove them to the regulators; this stifles the experimentation that automakers need to advance their products. NHTSA had already approved a brake fluid they considered safe – DOT 3 brake fluid, which is red and hygroscopic to promote internal rust. This completely different fluid, used in aircraft applications – the technically superior green LHM (Liquide Hydraulique Mineral) – took NHTSA two years to analyze for automotive use. Approval finally came in January 1969, so half the U.S. cars of the 1969 model year use red fluid and half use green fluid.

 

DESIGN VARIATIONS

PALLAS

In 1965 a luxury upgrade, the DS Pallas (after Greek goddess Pallas), was introduced. This included comfort features such as better noise insulation, a more luxurious (and optional leather) upholstery and external trim embellishments. From 1966 the Pallas model received a driver's seat with height adjustment.

 

STATION WAGON, FAMILIALE AND AMBULANCE

A station wagon version was introduced in 1958. It was known by various names in different markets (Break in France, Safari and Estate in the UK, Wagon in the US, and Citroën Australia used the terms Safari and Station-Wagon). It had a steel roof to support the standard roof rack. 'Familiales' had a rear seat mounted further back in the cabin, with three folding seats between the front and rear squabs. The standard Break had two side-facing seats in the main load area at the back.

 

The Ambulance configuration was similar to that of the Break, but with a 60/30 split in the rear folding seat to accommodate a stretcher. A 'Commerciale' version was also available for a time.

 

The Safari saw use as a camera car, notably by the BBC. The hydropneumatic suspension produces an unusually steady platform for filming while driving.

 

CONVERTIBLE

Rarest and most collectable of all DS variants, a convertible was offered from 1958 until 1973. The Cabriolet d'Usine (factory convertible) were built by French carrossier Henri Chapron, for the Citroën dealer network. It was an expensive car, so only 1,365 were sold. These DS convertibles used a special frame which was reinforced on the sidemembers and rear suspension swingarm bearing box, similar to, but not identical to the Break (Station Wagon) frame.

 

CHAPRON VARIATIONS

In addition, Chapron also produced a few coupés, non-works convertibles and special sedans (including the "Prestige", same wheelbase but with a central divider, and the "Lorraine" notchback).

 

BOSSAERT COUPE

Between 1959 and 1964, Hector Bossaert produced a coupé on a DS chassis shortened by 470 mm. While the front end remained unchanged, the rear end featured notchback styling.

 

THE REACTOR

In 1965, noted American auto customizer Gene Winfield created The Reactor, a Citroën DS chassis, with a turbocharged 180 hp (130 kW) flat-six engine from the Corvair driving the front wheels. Since the DS already had the engine behind the front wheels, the longer engine meant only one row of seats. This was draped in a streamlined, low slung, aluminum body.

 

The Reactor was seen in American Television programs of the era, such as Star Trek: The Original Series episode 2.25 ("Bread and Circuses)," Batman episodes 110 ("Funny Feline Felonies") and 111 (driven by Catwoman Eartha Kitt), and Bewitched, which devoted its episode 3.19 ("Super Car") to The Reactor.

 

MICHELIN PLR

The Michelin PLR is a mobile tire evaluation machine, based on the DS Break, built in 1972, later used for promotion.

Technical details

 

SUSPENSION

In a hydropneumatic suspension system, each wheel is connected, not to a spring, but to a hydraulic suspension unit consisting of a hydraulic accumulator sphere of about 12 cm in diameter containing pressurised nitrogen, a cylinder containing hydraulic fluid screwed to the suspension sphere, a piston inside the cylinder connected by levers to the suspension itself, and a damper valve between the piston and the sphere. A membrane in the sphere prevented the nitrogen from escaping. The motion of the wheels translated to a motion of the piston, which acted on the oil in the nitrogen cushion and provided the spring effect. The damper valve took place of the shock absorber in conventional suspensions. The hydraulic cylinder was fed with hydraulic fluid from the main pressure reservoir via a height corrector, a valve controlled by the mid-position of the anti-roll bar connected to the axle. If the suspension was too low, the height corrector introduced high-pressure fluid; if it was too high, it released fluid back to the fluid reservoir. In this manner, a constant ride height was maintained. A control in the cabin allowed the driver to select one of five heights: normal riding height, two slightly higher riding heights for poor terrain, and two extreme positions for changing wheels. (The correct term, oleopneumatic (oil-air), has never gained widespread use. Hydropneumatic (water-air) continues to be preferred overwhelmingly.)

 

The DS did not have a jack for lifting the car off the ground. Instead, the hydraulic system enabled wheel changes with the aid of a simple adjustable stand. To change a flat tyre, one would adjust the suspension to its topmost setting, insert the stand into a special peg near the flat tyre, then readjust the suspension to its lowermost setting. The flat tyre would then retract upwards and hover above ground, ready to be changed. This system, used on the SM also, was superseded on the CX by a screw jack that, after the suspension was raised to the high position, lifted the tire clear of the ground. The DS system, while impressive to use, sometimes dropped the car quite suddenly, especially if the stand was not placed precisely or the ground was soft or unlevel.

 

SOURCE AND RESERVE OF PRESSURE

The central part of the hydraulic system was the high pressure pump, which maintained a pressure of between 130 and 150 bar in two accumulators. These accumulators were very similar in construction to the suspension spheres. One was dedicated to the front brakes, and the other ran the other hydraulic systems. (On the simpler ID models, the front brakes operated from the main accumulator.) Thus in case of a hydraulic failure, the first indication would be that the steering became heavy, followed by the gearbox not working; only later would the brakes fail.

 

Two different hydraulic pumps were used. The DS used a seven-cylinder axial piston pump driven off two belts and delivering 175 bar (2,540 psi) of pressure. The ID19, with its simpler hydraulic system, had a single-cylinder pump driven by an eccentric on the camshaft.

 

GEARBOX AND CLUTCH

HYDRAULIQUE OR CITROMATIC

The DS was initially offered only with the "hydraulique" four-speed semi-automatic (bvh—"boîte de vitesses hydraulique") gearbox.

 

This was a four-speed gearbox and clutch, operated by a hydraulic controller. To change gears, the driver flicked a lever behind the steering wheel to the next position and eased-up on the accelerator pedal. The hydraulic controller disengaged the clutch, engaged the nominated gear, and re-engaged the clutch. The speed of engagement of the clutch was controlled by a centrifugal regulator sensing engine rpm and driven off the camshaft by a belt, the position of the butterfly valve in the carburettor (i.e., the position of the accelerator), and the brake circuit. When the brake was pressed, the engine idle speed dropped to an rpm below the clutch engagement speed, thus preventing friction while stopped in gear at traffic lights. When the brake was released, the idle speed increased to the clutch dragging speed. The car would then creep forward much like automatic transmission cars. This drop in idle throttle position also caused the car to have more engine drag when the brakes were applied even before the car slowed to the idle speed in gear, preventing the engine from pulling against the brakes. In the event of loss of hydraulic pressure (following loss of system fluid), the clutch would disengage, to prevent driving, while brake pressure reserves would allow safe braking to standstill.

 

MANUAL - FOUR SPEED AND FIVE-SPEED

The later and simpler ID19 had the same gearbox and clutch, manually operated. This configuration was offered as a cheaper option for the DS in 1963. The mechanical aspects of the gearbox and clutch were completely conventional and the same elements were used in the ID 19. In September 1970, Citroën introduced a five-speed manual gearbox, in addition to the original four-speed unit.

 

FULLY AUTOMATIC

In September 1971 Citroën introduced a 3-speed fully automatic Borg-Warner 35 transmission gearbox, on the DS 21 and later DS 23 models. It is ironic that the fully automatic transmission DS was never sold in the US market, where this type of transmission had gained market share so quickly that it became the majority of the market by this time. Many automatic DSs, fuel-injected DS 23 sedans with air conditioning, were sold in Australia.

 

ENGINES

The DS was originally designed around an air-cooled flat-six based on the design of the 2-cylinder engine of the 2CV, similar to the motor in the Porsche 911. Technical and monetary problems forced this idea to be scrapped.

 

Thus, for such a modern car, the engine of the original DS 19 was also old-fashioned. It was derived from the engine of the 11CV Traction Avant (models 11B and 11C). It was an OHV four-cylinder engine with three main bearings and wet liners, and a bore of 78 mm and a stroke of 100 mm, giving a volumetric displacement of 1911 cc. The cylinder head had been reworked; the 11C had a reverse-flow cast iron cylinder head and generated 60 hp (45 kW) at 3800 rpm; by contrast, the DS 19 had an aluminium cross-flow head with hemispherical combustion chambers and generated 75 hp (56 kW) at 4500 rpm.

 

Like the Traction Avant, the DS had the gearbox mounted in front of the engine, with the differential in between. Thus some consider the DS to be a mid engine front-wheel drive car.

 

The DS and ID powerplants evolved throughout its 20-year production life. The car was underpowered and faced constant mechanical changes to boost the performance of the four-cylinder engine. The initial 1911 cc three main bearing engine (carried forward from the Traction Avant) of the DS 19 was replaced in 1965 with the 1985 cc five-bearing wet-cylinder motor, becoming the DS 19a (called DS 20 from September 1969).

 

The DS 21 was also introduced for model year 1965. This was a 2175 cc, five main bearing engine; power was 109 hp This engine received a substantial increase in power with the introduction of Bosch electronic fuel injection for 1970, making the DS one of the first mass-market cars to use electronic fuel injection. Power of the carbureted version also increased slightly at the same time, owing to the employment of larger inlet valves.

 

Lastly, 1973 saw the introduction of the 2347 cc engine of the DS 23 in both carbureted and fuel-injected forms. The DS 23 with electronic fuel injection was the most powerful production model, producing 141 hp (105 kW).

 

IDs and their variants went through a similar evolution, generally lagging the DS by about one year. ID saloon models never received the DS 23 engine or fuel injection, although the Break/Familiale versions received the carburetted version of the DS 23 engine when it was introduced, supplemented the DS20 Break/Familiale.

 

The top of the range ID model, The DSuper5 (DP) gained the DS21 engine (the only model that this engine was retained in) for the 1973 model year and it was mated to a five-speed gearbox. This should not be confused with the 1985 cc DSuper fitted with an optional "low ratio" five-speed gearbox, or with the previous DS21M (DJ) five-speed.

 

IN POPULAR CULTURE

President Charles de Gaulle survived an assassination attempt at Le Petit-Clamart near Paris on August 22, 1962, planned by Algerian War veteran Jean-Marie Bastien-Thiry. The plan was to ambush the motorcade with machine guns, disable the vehicles, and then close in for the kill. De Gaulle praised the unusual abilities of his unarmoured DS with saving his life – the car was peppered with bullets, and the shots had punctured the tyres, but the car could still escape at full speed. This event was accurately recreated in the 1973 film The Day of the Jackal.

 

Beyond de Gaulle and the French aristocracy, the roomy DS also appealed to French taxi drivers.

 

Outside France, the car drew an eclectic customer mix, such as Cosmonaut Yuri Gagarin, Pope John XXIII, painter Marc Chagall, and actors Ken Berry, Jeff Bridges, and Rosamund Pike.

 

The DS appeared in several episodes of contemporary television series Mission: Impossible, including substantial appearances in 'The Slave' (ep. 2.06) and 'Robot' (ep. 4.09).

 

An ode to Jane Child's DS21 appears on her 1989 self-titled album.

 

In 1989, the film Back to the Future Part II featured a modified Citroen DS as a flying taxicab, when the main characters travel 30 years into the future (2015). Scarface (1983 film) with Al Pacino and the 2009 television series The Mentalist both feature the DS in key roles. According to Internet Movie Cars Database, the DS/ID has made over 2,000 film and television appearances so far.

 

Two films focus on the DS, including The Goddess of 1967 about a Japanese man purchasing a DS (goddess or déesse in French) in Australia, and 1995's Icelandic-Japanese road movie Cold Fever.

 

LEGACY

Citroën DS values have been rising – a 1973 DS 23 Injection Electronique "Decapotable" (Chapron Convertible) sold for EUR €176,250 (USD $209,738) at Christie's Rétromobile in February 2006. and a similar car sold by Bonhams in February 2009 brought EUR €343,497 (USD $440,436). On 18 September 2009 a 1966 DS21 Decapotable Usine was sold by Bonhams for a hammer price of UK£131,300. Bonhams sold another DS21 Decapotable (1973) on 23 January 2010 for EUR €189,000.

 

The DS's beloved place in French society was demonstrated in Paris on 9 October 2005 with a celebration of the 50th anniversary of its launch. 1,600 DS cars drove in procession past the Arc de Triomphe.

 

From 2005 to 2008, a young Frenchman named Manuel Boileau travelled around the world in a 1971 DS ambulance. It was an 80,000 kilometer journey across 38 countries called Lunaya World Tour. While traveling through Laos, he located the forlorn 1974 DS Prestige belonging to Sisavang Vatthana, the last King of the Kingdom of Laos, which is now preserved and restored by specialists in Bangkok.

 

In 2009, Groupe PSA created a new brand - DS Automobiles, intended as high quality, high specification variations on existing models, with differing mechanics and bodywork. This brand ranges across four models, the DS3, DS4, DS5, and the China-only SUV DS 6. The DS3, launched in March 2010, is based on Citroen's new C3, but is more customisable and unique, bearing some resemblance to the original DS, with its "Shark Fin" side pillar. These have created their own niches, with the DS4 being a mix of a crossover and a coupe and the DS5 mixing a coupe and an estate. Many feature hybrid-diesel engines to maximise efficiency.

INSTRUCTIONS AVAILABLE FOR P558 SUPERDUTY - MULTIPLE CONFIGURATIONS

 

On September 24, 2015, Ford unveiled the 2017 Ford Super Duty line at the 2015 State Fair of Texas. he frame is made from 95% high strength steel and the body (like the contemporary F-150) is made from 6000 series aluminum alloy. For the first time since 1999, both the Super Duty and F-150 lines are constructed using the same cab.

 

For 2017 production, the Super Duty line shares its powertrain lineup with its 2016 predecessor: a 6.2L gasoline V8, 6.8L V10 (F-450 and above), with a 6.7L diesel V8 available in all versions. The 6.2L gasoline V8 engine remains at 385 hp but torque rises from 405 lb-ft to 430 lb-ft. Additionally, the gasoline V8 produces its max torque at over 700 rpm less than the previous 405 lb-ft engine. The 6.7L diesel engine also remains at the same 440 hp (323 kW) but torque increases from 860 lb-ft upwards to 925 lb-ft.

 

The 2020 Super Duty debuted at the 2019 Chicago Auto Show. It features a revised grille and tailgate design, new wheel options, and higher-quality interior materials for the Limited trim. A new 7.3-liter gasoline engine is available. Nicknamed "Godzilla", it makes 430 horsepower and 475 lb-ft of torque.

 

Cab configurations continue to be 2-Door Regular Cab, 4-Door Super Cab, and 4-Door Super Crew Cab, with Short Box (6' 9") and Long Box (8') bed lengths. The truck will be available in F-250, F-350, and F-450 pickup truck models, and F-350, F-450, and F-550 chassis cab models. All will be available in both 4X2 and 4X4 configurations. The F-350 will be the only model available in either Single Rear Wheel (SRW) or Dual Rear Wheel (DRW) configurations, the F-450 and F-550 will only be available in a Dual Rear Wheel (DRW) configuration, and the F-250 will only be available in a Single Rear Wheel configuration.

The Citroën DS (French pronunciation: ​[si.tʁɔ.ˈɛn de ɛs]) is a front-engine, front-wheel-drive executive car manufactured and marketed by the French company Citroën from 1955 to 1975 in sedan, wagon/estate and convertible body configurations. Italian sculptor and industrial designer Flaminio Bertoni and the French aeronautical engineer André Lefèbvre styled and engineered the car. Paul Magès developed the hydropneumatic self-levelling suspension.

 

Noted for its aerodynamic, futuristic body design and innovative technology, the DS set new standards in ride quality, handling, and braking—and was the first production car equipped with disc brakes.

 

Citroën sold 1,455,746 examples, including 1,330,755 built at the manufacturer's Paris Quai André-Citroën production plant.

 

The DS came third in the 1999 Car of the Century poll recognizing the world's most influential auto designs and was named the most beautiful car of all time by Classic & Sports Car magazine

 

MODEL HISTORY

After 18 years of secret development as the successor to the Traction Avant, the DS 19 was introduced on 5 October 1955 at the Paris Motor Show. In the first 15 minutes of the show, 743 orders were taken, and orders for the first day totalled 12,000. During the 10 days of the show, the DS took in 80,000 deposits; a record that has stood for over 60 years.

 

Contemporary journalists said the DS pushed the envelope in the ride vs. handling compromise possible in a motor vehicle.

 

To a France still deep in reconstruction after the devastation of World War II, and also building its identity in the post-colonial world, the DS was a symbol of French ingenuity. The DS was distributed to many territories throughout the world.

 

It also posited the nation's relevance in the Space Age, during the global race for technology of the Cold War. Structuralist philosopher Roland Barthes, in an essay about the car, said that it looked as if it had "fallen from the sky". An American advertisement summarised this selling point: "It takes a special person to drive a special car".

 

Because they were owned by the technologically aggressive tire manufacturer Michelin, Citroën had designed their cars around the technically superior radial tire since 1948, and the DS was no exception.

 

The car featured a novel hydropneumatic suspension including an automatic leveling system and variable ground clearance, developed in-house by Paul Magès. This suspension allowed the DS to travel quickly on the poor road surfaces common in France.

 

In addition, the vehicle had power steering and a semi-automatic transmission (the transmission required no clutch pedal, but gears still had to be shifted by hand), though the shift lever controlled a powered hydraulic shift mechanism in place of a mechanical linkage, and a fibreglass roof which lowered the centre of gravity and so reduced weight transfer. Inboard front brakes (as well as independent suspension) reduced unsprung weight. Different front and rear track widths and tyre sizes reduced the unequal tyre loading, which is well known to promote understeer, typical of front-engined and front-wheel drive cars.

 

As with all French cars, the DS design was affected by the tax horsepower system, which effectively mandated very small engines. Unlike the Traction Avant predecessor, there was no top-of-range model with a powerful six-cylinder engine. Citroën had planned an air-cooled flat-6 engine for the car, but did not have the funds to put the prototype engine into production.

 

The DS placed third in the 1999 Car of the Century competition, and fifth on Automobile Magazine's "100 Coolest Cars" listing in 2005. It was also named the most beautiful car of all time by Classic & Sports Car magazine after a poll of 20 world-renowned car designers, including Giorgetto Giugiaro, Ian Callum, Roy Axe, Paul Bracq, and Leonardo Fioravanti.

 

NAME

Both the DS and its simpler sibling, the ID, used a punning name. "DS" is pronounced in French as "Déesse" (goddess); "ID" is pronounced as "Idée" (idea). An intermediate model was called the DW.

 

MOTORSPORT

The DS was successful in motorsports like rallying, where sustained speeds on poor surfaces are paramount, and won the Monte Carlo Rally in 1959. In the 1000 Lakes Rally, Pauli Toivonen drove a DS19 to victory in 1962.

 

In 1966, the DS won the Monte Carlo Rally again, with some controversy as the competitive BMC Mini-Cooper team was disqualified due to rule infractions. Ironically, Mini was involved with DS competition again two years later, when a drunk driver in a Mini in Sydney Australia crashed into the DS that was leading the 1968 London–Sydney Marathon, 98 miles from the finish line. The DS was still competitive in the grueling 1974 London-Sahara-Munich World Cup Rally, where it won over 70 other cars, only 5 of which even completed the entire event.

 

TECHNICAL INNOVATION - HYDRAULIC SYSTEMS

In conventional cars, hydraulics are only used in brakes and power steering. In the DS they were also used for the suspension, clutch and transmission. The cheaper 1957 ID19 did have manual steering and a simplified power-braking system. An engine driven pump pressurizes the closed system to 2,400 pounds per square inch.

 

At a time when few passenger vehicles had independent suspension on all wheels, the application of the hydraulic system to the car's suspension system to provide a self-levelling system was an innovative move. This suspension allowed the car to achieve sharp handling combined with very high ride quality, frequently compared to a "magic carpet".

 

The hydropneumatic suspension used was pioneered the year before, on the rear of another car from Citroën, the top of range Traction Avant 15CV-H.

 

IMPACT ON CITROEN BRAND DEVELOPMENT

The 1955 DS cemented the Citroën brand name as an automotive innovator, building on the success of the Traction Avant, which had been the world's first mass-produced unitary body front-wheel-drive car in 1934. In fact, the DS caused such a huge sensation that Citroën was apprehensive that future models would not be of the same bold standard. No clean sheet new models were introduced from 1955 to 1970.

 

The DS was a large, expensive executive car and a downward brand extension was attempted, but without result. Throughout the late 1950s and 1960s Citroën developed many new vehicles for the very large, profitable market segments between the 2CV and the DS, occupied by vehicles like the Peugeot 403, Renault 16 and Ford Cortina, but none made it into production. Either they had uneconomic build costs, or were ordinary "me too" cars, not up to the company's high standard of innovation. As Citroën was owned by Michelin from 1934 to 1974 as a sort of research laboratory, such broad experimentation was possible. Michelin after all was getting a powerful advertisement for the capabilities of the radial tire Michelin had invented, when such experimentation was successful.

 

New models based on the small, utilitarian 2CV economy car were introduced, notably the 1961 Ami. It was also designed by Flaminio Bertoni and aimed to combine Three-box styling with the chassis of the 2CV. The Ami was very successful in France, but less so on export markets. Many found the styling controversial, and the car noisy and underpowered. The Dyane, was a modernised 2CV with a hatchback, competed with the 2CV inspired Renault 4 Hatchback. All these 2 cylinder models were very small, so there remained a wide market gap to the DS range all through the 1960s.

 

In 1970, Citroën finally introduced a car to target the mid-range - the Citroën GS, which won the "European car of the Year" for 1971 and sold 2.5 million units. It combined a small 55 horsepower flat-4 air-cooled engine with Hydropneumatic suspension. The intended 106 horsepower Wankel rotary-engined version with more power did not reach full production.

 

REPLACING THE DS

The DS remained popular and competitive throughout its production run. Its peak production year was 1970. Certain design elements like the somewhat narrow cabin, column-mounted gearstick, and separate fenders began to seem a little old-fashioned in the 1970s.

 

Citroën invested enormous resources to design and launch an entirely new vehicle in 1970, the SM, which was in effect a thoroughly modernized DS, with similar length, but greater width. The manual gearbox was a modified DS unit. The front disc brakes were the same design. Axles, wheel bearings, steering knuckles, and hydraulic components were either DS parts or modified DS parts.

 

The SM had a different purpose than replacing the 15-year-old DS design however - it was meant to launch Citroën into a completely new luxury grand touring market segment. Only fitted with a costly, exotic Maserati engine, the SM was faster and much more expensive than the DS. The SM was not designed to be a practical 4-door saloon suitable as a large family car, the key market for vehicles of this type in Europe. Typically, manufacturers would introduce low-volume coupés based on parts shared with an existing saloon, not as unique models, a contemporary example being the Mercedes-Benz SLC-Class.

 

The SM's high price and limited utility of the 2+2 seating configuration, meant the SM as actually produced could not seize the mantle from the DS.

 

So, while the design funds invested would allow the DS to be replaced by two cars - a 'modern DS' and the smaller CX, it was left to the CX alone to provide Citroën's large family or executive car in the model range.

 

The last DS came off the production line on 24 April 1975 - the manufacturer had taken the elementary precaution of building up approximately eight-month's of inventory of the "break" (estate/station wagon) version of the DS, to cover the period till Autumn 1975 when the estate/station wagon version of the CX would be introduced.

 

DEVELOPMENT

The DS always maintained its size and shape, with easily removable, unstressed body panels, but certain design changes did occur. During the 20-year production life improvements were made on an ongoing basis.

ID 19 submodel to extend brand downwards (1957–69)

 

The 1955 DS19 was 65% more expensive than the car it replaced, the Citroën Traction Avant. This affected potential sales in a country still recovering economically from World War II, so a cheaper submodel, the Citroën ID, was introduced in 1957.

 

The ID shared the DS's body but was less powerful and luxurious. Although it shared the engine capacity of the DS engine (at this stage 1,911 cc), the ID provided a maximum power output of only 69 hp compared to the 75 hp claimed for the DS19. Power outputs were further differentiated in 1961 when the DS19 acquired a Weber-32 twin bodied carburettor, and the increasing availability of higher octane fuel enabled the manufacturer to increase the compression ratio from 7.5:1 to 8.5:1. A new DS19 now came with a promised 83 hp of power. The ID19 was also more traditional mechanically: it had no power steering and had conventional transmission and clutch instead of the DS's hydraulically controlled set-up. Initially the basic ID19 was sold on the French market with a price saving of more than 25% against the DS, although the differential was reduced at the end of 1961 when the manufacturer quietly withdrew the entry level ID19 "Normale" from sale. A station wagon variant, the ID Break, was introduced in 1958.

 

D SPECIAL AND D SUPER (1970–75)

The ID was replaced by the D Spécial and D Super in 1970, but these retained the lower specification position in the range. The D Super was available with the DS21 2175ccm engine and a 5 speed gearbox, and named the D Super 5.

 

SERIE 2 - NOSE REDESIGN IN 1962

In September 1962, the DS was restyled with a more aerodynamically efficient nose, better ventilation and other improvements. It retained the open two headlamp appearance, but was available with an optional set of driving lights mounted on the front fenders. All models in the range changed nose design at the same time, including the ID and station wagon models.

Series 3 - Nose redesign in 1967 with Directional headlights

 

In late 1967, for the 1968 model year, the DS and ID was again restyled, by Robert Opron, who also styled the 1970 SM and 1974 CX. This version had a more streamlined headlamp design, giving the car a notably shark-like appearance. This design had four headlights under a smooth glass canopy, and the inner set swivelled with the steering wheel. This allowed the driver to see "around" turns, especially valuable on twisting roads driven at high speed at night.

 

Behind each glass cover lens, the inboard high-beam headlamp swivels by up to 80° as the driver steers, throwing the beam along the driver's intended path rather than uselessly across the curved road. The outboard low-beam headlamps are self-leveling in response to pitching caused by acceleration and braking.

 

However, this feature was not allowed in the US at the time (see World Forum for Harmonization of Vehicle Regulations), so a version with four exposed headlights that did not swivel was made for the US market.

 

This 'turning headlight' feature was new to the market - it had only been seen before on the very rare three headlight 1935 Tatra 77A. The Tucker, which never was mass-produced, had a central headlight that turned with the steering. 45 years later, it is now a commonly available feature, even in the United States.

 

NEW GREEN HYDRAULIC FLUID

The original hydropneumatic system used a vegetable oil liquide hydraulique végétal (LHV), similar to that used in other cars at the time, but later switched to a synthetic fluid liquide hydraulique synthétique (LHS). Both of these had the disadvantage that they are hygroscopic, as is the case with most brake fluids. Disuse allows water to enter the hydraulic components causing deterioration and expensive maintenance work. The difficulty with hygroscopic hydraulic fluid was exacerbated in the DS/ID due to the extreme rise and fall in the fluid level in the reservoir, which went from nearly full to nearly empty when the suspension extended to maximum height and the six accumulators in the system filled with fluid. With every "inhalation" of fresh moisture- (and dust-) laden air, the fluid absorbed more water.

 

For the 1967 model year, Citroën introduced a new mineral oil-based fluid LHM (Liquide Hydraulique Minéral). This fluid was much less harsh on the system. LHM remained in use within Citroën until the Xantia was discontinued in 2001.

 

LHM required completely different materials for the seals. Using either fluid in the incorrect system would completely destroy the hydraulic seals very quickly. To help avoid this problem, Citroën added a bright green dye to the LHM fluid and also painted all hydraulic elements bright green. The former LHS parts were painted black.

 

All models, including the station wagon and ID, were upgraded at the same time. The hydraulic fluid changed to the technically superior LHM in all markets except the US and Canada, where the change did not take place until January 1969, due to local regulations.

 

INTERNATIONAL SALES AND PRODUCTION

The DS was primarily manufactured at the Quai André-Citroën in the Javel neighborhood of Paris, with other manufacturing facilities in the United Kingdom, South Africa, the former Yugoslavia (mostly Break Ambulances), and Australia.

 

Australia constructed their own D variant in the 1960s at Heidelberg, Victoria, identified as the ID 19 "Parisienne." Australian market cars were fitted with options as standard equipment such as the "DSpecial DeLuxe" that were not available on domestic European models.

 

Until 1965, cars were assembled at the manufacturer's Slough premises, to the west of London, using a combination of French made knock down kits and locally sourced components, some of them machined on site. A French electrical system superseded the British one on the Slough cars in 1962, giving rise to a switch to "continental style" negative earthing. After 1965 cars for the British market were imported fully assembled from the company's French plant. The British-built cars are distinguished by their leather seats, wooden (early ID19 models) one piece plastic (early DS19 models) dashboards, chromed number plate mount let into the front bumper, and (on pre-1962 cars) Lucas-made electrics. These were all right hand drive cars.

 

The DS was built and sold in South Africa from 1959 to 1975.

 

The DS was sold in Japan, but the models were built in France and left hand drive.

 

DS IN NORTH AMERICA

The DS was sold in North America from 1956 to 1972. Despite its popularity in Europe, it didn't sell well in the United States, and little better in Canada. While promoted as a luxury car, it did not have the basic features that American buyers expected to find on such a vehicle, such as an automatic transmission, air conditioning, power windows, or a powerful engine. The DS was designed specifically to address the French market, with punitive tax horsepower taxation of large engines, as well as very poor roads – it's no great mystery that it was a fish out of water when those constraints were removed.

 

Jay Leno described the sporadic supply of spare parts as a problem for 1970s era customers, based on his early experiences working at a Citroën dealer in Boston.

 

The DS was expensive, with a 115 hp (86 kW) vehicle costing $4,170 in 1969, when the price was $4,500 for a 360 hp (268 kW) Buick Electra 225 4 door sedan. For all years, 38,000 units were sold.

 

US regulations at the time also banned one of the car's more advanced features: its composite headlamps with aerodynamic covered lenses. Based on legislation that dated from 1940, all automobiles sold in the U.S. were required to have round, sealed beam headlamps that produced a meager 75,000 candlepower. The powerful quartz iodine swiveling headlamps designed for the 1968 model DS represented so many performance improvements at once that they were far beyond what the regulations could allow.[50] Even the aerodynamic headlight covers were illegal – as seen on the 1968 Jaguar E-Type. It took the lobbying muscle of Ford to point out that the government was requiring two contradictory things – safety, by ensuring that all headlights were best-of-breed circa 1940, and fuel economy through the CAFE standard – by definition, cars with poor aerodynamics are sacrificing fuel economy. Composite bulb lamps and aerodynamic covered headlights were not permitted until 1983.

 

The European lamps were legal in Canada, including the directional headlamps.

 

The hydraulic fluid change in 1967 was another brain teaser for U.S. automotive regulators at the Department of Transportation. NHTSA follows the precautionary principle, also used by the Food and Drug Administration, where new innovations are prohibited until their developers can prove them to the regulators; this stifles the experimentation that automakers need to advance their products. NHTSA had already approved a brake fluid they considered safe – DOT 3 brake fluid, which is red and hygroscopic to promote internal rust. This completely different fluid, used in aircraft applications – the technically superior green LHM (Liquide Hydraulique Mineral) – took NHTSA two years to analyze for automotive use. Approval finally came in January 1969, so half the U.S. cars of the 1969 model year use red fluid and half use green fluid.

 

DESIGN VARIATIONS

PALLAS

In 1965 a luxury upgrade, the DS Pallas (after Greek goddess Pallas), was introduced. This included comfort features such as better noise insulation, a more luxurious (and optional leather) upholstery and external trim embellishments. From 1966 the Pallas model received a driver's seat with height adjustment.

 

STATION WAGON, FAMILIALE AND AMBULANCE

A station wagon version was introduced in 1958. It was known by various names in different markets (Break in France, Safari and Estate in the UK, Wagon in the US, and Citroën Australia used the terms Safari and Station-Wagon). It had a steel roof to support the standard roof rack. 'Familiales' had a rear seat mounted further back in the cabin, with three folding seats between the front and rear squabs. The standard Break had two side-facing seats in the main load area at the back.

 

The Ambulance configuration was similar to that of the Break, but with a 60/30 split in the rear folding seat to accommodate a stretcher. A 'Commerciale' version was also available for a time.

 

The Safari saw use as a camera car, notably by the BBC. The hydropneumatic suspension produces an unusually steady platform for filming while driving.

 

CONVERTIBLE

Rarest and most collectable of all DS variants, a convertible was offered from 1958 until 1973. The Cabriolet d'Usine (factory convertible) were built by French carrossier Henri Chapron, for the Citroën dealer network. It was an expensive car, so only 1,365 were sold. These DS convertibles used a special frame which was reinforced on the sidemembers and rear suspension swingarm bearing box, similar to, but not identical to the Break (Station Wagon) frame.

 

CHAPRON VARIATIONS

In addition, Chapron also produced a few coupés, non-works convertibles and special sedans (including the "Prestige", same wheelbase but with a central divider, and the "Lorraine" notchback).

 

BOSSAERT COUPE

Between 1959 and 1964, Hector Bossaert produced a coupé on a DS chassis shortened by 470 mm. While the front end remained unchanged, the rear end featured notchback styling.

 

THE REACTOR

In 1965, noted American auto customizer Gene Winfield created The Reactor, a Citroën DS chassis, with a turbocharged 180 hp (130 kW) flat-six engine from the Corvair driving the front wheels. Since the DS already had the engine behind the front wheels, the longer engine meant only one row of seats. This was draped in a streamlined, low slung, aluminum body.

 

The Reactor was seen in American Television programs of the era, such as Star Trek: The Original Series episode 2.25 ("Bread and Circuses)," Batman episodes 110 ("Funny Feline Felonies") and 111 (driven by Catwoman Eartha Kitt), and Bewitched, which devoted its episode 3.19 ("Super Car") to The Reactor.

 

MICHELIN PLR

The Michelin PLR is a mobile tire evaluation machine, based on the DS Break, built in 1972, later used for promotion.

Technical details

 

SUSPENSION

In a hydropneumatic suspension system, each wheel is connected, not to a spring, but to a hydraulic suspension unit consisting of a hydraulic accumulator sphere of about 12 cm in diameter containing pressurised nitrogen, a cylinder containing hydraulic fluid screwed to the suspension sphere, a piston inside the cylinder connected by levers to the suspension itself, and a damper valve between the piston and the sphere. A membrane in the sphere prevented the nitrogen from escaping. The motion of the wheels translated to a motion of the piston, which acted on the oil in the nitrogen cushion and provided the spring effect. The damper valve took place of the shock absorber in conventional suspensions. The hydraulic cylinder was fed with hydraulic fluid from the main pressure reservoir via a height corrector, a valve controlled by the mid-position of the anti-roll bar connected to the axle. If the suspension was too low, the height corrector introduced high-pressure fluid; if it was too high, it released fluid back to the fluid reservoir. In this manner, a constant ride height was maintained. A control in the cabin allowed the driver to select one of five heights: normal riding height, two slightly higher riding heights for poor terrain, and two extreme positions for changing wheels. (The correct term, oleopneumatic (oil-air), has never gained widespread use. Hydropneumatic (water-air) continues to be preferred overwhelmingly.)

 

The DS did not have a jack for lifting the car off the ground. Instead, the hydraulic system enabled wheel changes with the aid of a simple adjustable stand. To change a flat tyre, one would adjust the suspension to its topmost setting, insert the stand into a special peg near the flat tyre, then readjust the suspension to its lowermost setting. The flat tyre would then retract upwards and hover above ground, ready to be changed. This system, used on the SM also, was superseded on the CX by a screw jack that, after the suspension was raised to the high position, lifted the tire clear of the ground. The DS system, while impressive to use, sometimes dropped the car quite suddenly, especially if the stand was not placed precisely or the ground was soft or unlevel.

 

SOURCE AND RESERVE OF PRESSURE

The central part of the hydraulic system was the high pressure pump, which maintained a pressure of between 130 and 150 bar in two accumulators. These accumulators were very similar in construction to the suspension spheres. One was dedicated to the front brakes, and the other ran the other hydraulic systems. (On the simpler ID models, the front brakes operated from the main accumulator.) Thus in case of a hydraulic failure, the first indication would be that the steering became heavy, followed by the gearbox not working; only later would the brakes fail.

 

Two different hydraulic pumps were used. The DS used a seven-cylinder axial piston pump driven off two belts and delivering 175 bar (2,540 psi) of pressure. The ID19, with its simpler hydraulic system, had a single-cylinder pump driven by an eccentric on the camshaft.

 

GEARBOX AND CLUTCH

HYDRAULIQUE OR CITROMATIC

The DS was initially offered only with the "hydraulique" four-speed semi-automatic (bvh—"boîte de vitesses hydraulique") gearbox.

 

This was a four-speed gearbox and clutch, operated by a hydraulic controller. To change gears, the driver flicked a lever behind the steering wheel to the next position and eased-up on the accelerator pedal. The hydraulic controller disengaged the clutch, engaged the nominated gear, and re-engaged the clutch. The speed of engagement of the clutch was controlled by a centrifugal regulator sensing engine rpm and driven off the camshaft by a belt, the position of the butterfly valve in the carburettor (i.e., the position of the accelerator), and the brake circuit. When the brake was pressed, the engine idle speed dropped to an rpm below the clutch engagement speed, thus preventing friction while stopped in gear at traffic lights. When the brake was released, the idle speed increased to the clutch dragging speed. The car would then creep forward much like automatic transmission cars. This drop in idle throttle position also caused the car to have more engine drag when the brakes were applied even before the car slowed to the idle speed in gear, preventing the engine from pulling against the brakes. In the event of loss of hydraulic pressure (following loss of system fluid), the clutch would disengage, to prevent driving, while brake pressure reserves would allow safe braking to standstill.

 

MANUAL - FOUR SPEED AND FIVE-SPEED

The later and simpler ID19 had the same gearbox and clutch, manually operated. This configuration was offered as a cheaper option for the DS in 1963. The mechanical aspects of the gearbox and clutch were completely conventional and the same elements were used in the ID 19. In September 1970, Citroën introduced a five-speed manual gearbox, in addition to the original four-speed unit.

 

FULLY AUTOMATIC

In September 1971 Citroën introduced a 3-speed fully automatic Borg-Warner 35 transmission gearbox, on the DS 21 and later DS 23 models. It is ironic that the fully automatic transmission DS was never sold in the US market, where this type of transmission had gained market share so quickly that it became the majority of the market by this time. Many automatic DSs, fuel-injected DS 23 sedans with air conditioning, were sold in Australia.

 

ENGINES

The DS was originally designed around an air-cooled flat-six based on the design of the 2-cylinder engine of the 2CV, similar to the motor in the Porsche 911. Technical and monetary problems forced this idea to be scrapped.

 

Thus, for such a modern car, the engine of the original DS 19 was also old-fashioned. It was derived from the engine of the 11CV Traction Avant (models 11B and 11C). It was an OHV four-cylinder engine with three main bearings and wet liners, and a bore of 78 mm and a stroke of 100 mm, giving a volumetric displacement of 1911 cc. The cylinder head had been reworked; the 11C had a reverse-flow cast iron cylinder head and generated 60 hp (45 kW) at 3800 rpm; by contrast, the DS 19 had an aluminium cross-flow head with hemispherical combustion chambers and generated 75 hp (56 kW) at 4500 rpm.

 

Like the Traction Avant, the DS had the gearbox mounted in front of the engine, with the differential in between. Thus some consider the DS to be a mid engine front-wheel drive car.

 

The DS and ID powerplants evolved throughout its 20-year production life. The car was underpowered and faced constant mechanical changes to boost the performance of the four-cylinder engine. The initial 1911 cc three main bearing engine (carried forward from the Traction Avant) of the DS 19 was replaced in 1965 with the 1985 cc five-bearing wet-cylinder motor, becoming the DS 19a (called DS 20 from September 1969).

 

The DS 21 was also introduced for model year 1965. This was a 2175 cc, five main bearing engine; power was 109 hp This engine received a substantial increase in power with the introduction of Bosch electronic fuel injection for 1970, making the DS one of the first mass-market cars to use electronic fuel injection. Power of the carbureted version also increased slightly at the same time, owing to the employment of larger inlet valves.

 

Lastly, 1973 saw the introduction of the 2347 cc engine of the DS 23 in both carbureted and fuel-injected forms. The DS 23 with electronic fuel injection was the most powerful production model, producing 141 hp (105 kW).

 

IDs and their variants went through a similar evolution, generally lagging the DS by about one year. ID saloon models never received the DS 23 engine or fuel injection, although the Break/Familiale versions received the carburetted version of the DS 23 engine when it was introduced, supplemented the DS20 Break/Familiale.

 

The top of the range ID model, The DSuper5 (DP) gained the DS21 engine (the only model that this engine was retained in) for the 1973 model year and it was mated to a five-speed gearbox. This should not be confused with the 1985 cc DSuper fitted with an optional "low ratio" five-speed gearbox, or with the previous DS21M (DJ) five-speed.

 

IN POPULAR CULTURE

President Charles de Gaulle survived an assassination attempt at Le Petit-Clamart near Paris on August 22, 1962, planned by Algerian War veteran Jean-Marie Bastien-Thiry. The plan was to ambush the motorcade with machine guns, disable the vehicles, and then close in for the kill. De Gaulle praised the unusual abilities of his unarmoured DS with saving his life – the car was peppered with bullets, and the shots had punctured the tyres, but the car could still escape at full speed. This event was accurately recreated in the 1973 film The Day of the Jackal.

 

Beyond de Gaulle and the French aristocracy, the roomy DS also appealed to French taxi drivers.

 

Outside France, the car drew an eclectic customer mix, such as Cosmonaut Yuri Gagarin, Pope John XXIII, painter Marc Chagall, and actors Ken Berry, Jeff Bridges, and Rosamund Pike.

 

The DS appeared in several episodes of contemporary television series Mission: Impossible, including substantial appearances in 'The Slave' (ep. 2.06) and 'Robot' (ep. 4.09).

 

An ode to Jane Child's DS21 appears on her 1989 self-titled album.

 

In 1989, the film Back to the Future Part II featured a modified Citroen DS as a flying taxicab, when the main characters travel 30 years into the future (2015). Scarface (1983 film) with Al Pacino and the 2009 television series The Mentalist both feature the DS in key roles. According to Internet Movie Cars Database, the DS/ID has made over 2,000 film and television appearances so far.

 

Two films focus on the DS, including The Goddess of 1967 about a Japanese man purchasing a DS (goddess or déesse in French) in Australia, and 1995's Icelandic-Japanese road movie Cold Fever.

 

LEGACY

Citroën DS values have been rising – a 1973 DS 23 Injection Electronique "Decapotable" (Chapron Convertible) sold for EUR €176,250 (USD $209,738) at Christie's Rétromobile in February 2006. and a similar car sold by Bonhams in February 2009 brought EUR €343,497 (USD $440,436). On 18 September 2009 a 1966 DS21 Decapotable Usine was sold by Bonhams for a hammer price of UK£131,300. Bonhams sold another DS21 Decapotable (1973) on 23 January 2010 for EUR €189,000.

 

The DS's beloved place in French society was demonstrated in Paris on 9 October 2005 with a celebration of the 50th anniversary of its launch. 1,600 DS cars drove in procession past the Arc de Triomphe.

 

From 2005 to 2008, a young Frenchman named Manuel Boileau travelled around the world in a 1971 DS ambulance. It was an 80,000 kilometer journey across 38 countries called Lunaya World Tour. While traveling through Laos, he located the forlorn 1974 DS Prestige belonging to Sisavang Vatthana, the last King of the Kingdom of Laos, which is now preserved and restored by specialists in Bangkok.

 

In 2009, Groupe PSA created a new brand - DS Automobiles, intended as high quality, high specification variations on existing models, with differing mechanics and bodywork. This brand ranges across four models, the DS3, DS4, DS5, and the China-only SUV DS 6. The DS3, launched in March 2010, is based on Citroen's new C3, but is more customisable and unique, bearing some resemblance to the original DS, with its "Shark Fin" side pillar. These have created their own niches, with the DS4 being a mix of a crossover and a coupe and the DS5 mixing a coupe and an estate. Many feature hybrid-diesel engines to maximise efficiency.

 

WIKIPEDIA

The baseline configuration of the Oshkart SMTV (Scalable Medium Tactical Vehicle) family, the Mk601A is the standard two-door 6x6 cargo hauler configuration.

  

Features include opening doors and top hatch, a cab capable of seating 2 minifigs with body armor and headgear, foldable gunner’s seat, turning front wheels, center-pivoting rear axles, and spare tire with lift arm.

  

A special thanks needs to be given to Abdullah750Pakistan. This originally started as a project to clean up and make a buildable and more minifig-friendly version of his Ural 63708. As you can see though, it’s turned into a project to create a series of trucks in the same vein of the Oshkosh MTVR, Navistar 7000 MV, and Ural 63704-0010 families.

  

As with my other builds, all parts used in this are real production pieces.

Lovely weather today. I love the smell of Proofide in the morning.

 

I finally decided that the Carradice is cool, but I'd rather have more capacity. A rack is almost infinitely expandable. This bike is much better prepared now for camping and pizza-carrying.

 

The panniers are a couple of new faux army-surplus canvas backpacks. Didn't have to modify them at all! The straps are looped once around the top rail of the rack, and then criss-crossed and clicked into place at the D-rings on the bottom of the bags.

This is the rare "V" configuration shot where the winner (lane 4) is ahead and everyone fans out like a bunch of geese behind him (e.g. the further from the center of the track, the further back you are). I don't know that I have seen this exact phenomenon before.

 

This was a heat, not the finals.

Nikon D800E + 70-200mm F/2.8 Nikkor Lens vs. Sony A7r + 35mm F/2.8 Carl Zeiss Lens! Both in 45surfer bracket configurations, with Sony NEX-6 cameras attached to the upper cameras with a bracket, for shooting stills and video at the same time! Guess which is heavier! :) The new 45surfer rig is a bit lighter, but that will change a bit when Sony comes out with longer zooms for the Sony A7r.

 

Both are great! The Sony NEX-6 bracketed to the D800E has the 50mm F/1.8 lens on it, while the Sony NEX-6 bracketed to the Sony A7R has the 35mm F/2.8 lens on it!

+++ DISCLAIMER +++

Nothing you see here is real, even though the conversion or the presented background story might be based historical facts. BEWARE!

  

Some background:

The P-74 "Charger" was a fighter aircraft built by Lockheed for the United States Army Air Forces (USAAF). Its configuration was unusual as it was designed as a twin boom pusher configuration, where the propeller is mounted in the rear of the fuselage, pushing the aircraft forward.

 

The P-74 entered service with the USAAF in late 1944, its conception dated back to 1939 when the U.S. Army Air Corps requested with the Circular Proposal R40C domestic manufacturers to develop high performance fighter types, allowing (even demanding) unusual configurations. Lockheed did not respond immediately and missed the chance to sign a development contract in mid-1940 until early 1941. Twenty-three proposals were submitted to R40C, and after a fist selection of ideas three companies, Vultee with the large XP-54 Swoose Goose, Curtiss with its XP-55 Ascender and Northrop's XP-56 Black Bullet were able to secure prototype contracts.

 

Vultee eventually won the competition, but all these innovative new aircraft suffered from various flaws or development delays, missing various performance goals, so that none ever entered service.

 

In the meantime, Lockheed had been working on the 1939 request in the background on a private venture basis, as it was clear that by 1944 a successor to the company's own P-38 Lightning had to be offered to the USAAC.

The new North American P-51 Mustang was also a sharp competitor, esp. for the Pacific conflict theatre where long range was needed. This role was filled out very well by the P-38, but it was a relatively large and complicated aircraft, so an alternative with a single engine was strived for. Even though jet engines already showed their potential, it was clear that the requested range for the new type could only be achieved through a piston engine.

 

This aircraft became the XP-74, originally christened “Laelaps”, following Lockheed’s tradition, after a female Greek mythological dog who never failed to catch what she was hunting. It was presented as a mock-up to USAAC officials on August 8th 1942 and immediately found sponsorship: with the disappointing results from the XP-54,55 and 56 was immediately ushered into the prototype stage. Its name, though, was rejected, and the more common name “Charger” was adopted.

 

Just like Lockheed’s successful P-38 the XP-74 Charger was designed as a twin-boom aircraft, but it was driven by only a single Packard (License-built Rolls Royce Merlin) V-1650 pusher engine in the aft part of the fuselage. The tail was mounted rearward between two mid-wing booms, with a four-bladed 12-ft propeller between them. The design also included a "ducted wing section" developed by the NACA that enabled installation of cooling radiators and intercoolers in the wing root section.

 

The advantages of a pusher design are that the view forward is unobstructed and armament can be concentrated in the nose, while a major drawback is difficulty in escaping from the aircraft in an emergency, as the pilot could get drawn into the propeller blades. Lockheed deliberated between systems that would eject the pilot, or jettison the propeller or the engine, via a system of explosive bolts. Lockheed eventually installed an early ejector seat which was driven by pressurized air, combined with a mechanism that would blow the canopy off. The system was successfully tested in summer 1943, even though skepticism remained among pilots.

 

Initial armament comprised one 20mm Hispano cannon and four 12.7mm Browning machine guns, the same as in the P-38, but two machine guns were relocated from the nose into the front ends of the tail booms because of the new aircraft’s smaller overall dimensions.

 

The first prototype was ready in October 1943, with a different engine and heavier armor fitted. The second prototype was built to this specification from the start, which would become the serial production standard, the P-74A.

The P-74A used the new V-1650-9 engine, a version of the Merlin that included Simmons automatic supercharger boost control with water injection, allowing War Emergency Power as high as 2,218 hp (1,500 kW). Another change concerned the armament: a longer weapon range was deemed necessary, so the gun armament was changed into four 20mm Hispano cannons, two of the placed in the fuselage nose and one in each tail boom front end. Each gun was supplied with 250 RPG.

 

Alternatively, a nose installment with a single 37mm cannon and two 12.7mm Browning MGs was tested on the first prototype, but this arrangement was found to be less effective than the four 20mm cannons. Another factor that turned this option down was the more complicated logistics demands for three different calibers in one aircraft.

 

The P-74A was ready for service in summer 1944, but its deployment into the Pacific region took until December – the 5th Air Force first units replaced most of its P-38 and also early P-47Ds with the P-74A.These new aircraft had their first clashes with Japanese forces in January 1945.

 

The P-74 was used in a variety of roles. It was designed as an intreceptor against bombers, but its good range and handling at all altitudes made it suitable for tasks like fighter sweeps against enemy airfields, support for U.S. ground forces and protection of sea convoys and transport routes.

While the P-74 could not out-turn the A6M Zero and most other Japanese fighters when flying below 200 mph (320 km/h), its superior speed coupled with a good rate of climb meant that it could utilize energy tactics, making multiple high-speed passes at its target. Also, its focused firepower was deadly to lightly armored Japanese warplanes.

 

Because of its late service introduction, only 305 P-74s were ever produced until the end of hostilities, and they were exclusively used in the Pacific theatre. The P-74's service record shows mixed results, but usually because of misinformation. P-74s have been described as being harder to fly than traditional, single-engined aircraft, but this was because of inadequate training in the first few months of service.

Another drawback was the ejection seat system – it worked basically well, but the tank for the pressurized air turned out to be very vulnerable to enemy fire. Several P-74s literally exploded in midair after cannon fire hits, and this poeblem could only be cured when the tank section behind the cockpit received a more rigid structure and additional armor. Anyway, the P-74 was quickly retired after WWII, as the USAAF focussed on P-47 and P-51.

The kit and its assembly:

This whif was inspired by a CG rendition of a Saab J21 in a natural metal finish and with (spurious) USAAF markings, probably a skin for a flight simulator. Anyway, I was more or less enchanted by the NMF on the Saab – I had to build one, and it would become the P-74, the only USAF fighter code that had never been used.

 

The kit is the venerable Heller Saab J21A, an “old style” design with raised panel lines. But it is still around and affordable. No big mods were made to the kit during its transition into a USAAF fighter, even though I changed some minor things:

● Main landing gear was completely exchanged through struts from an Airfix A-1 Skyraider and the wheels from a Hasegawa P-51D; thin wire was added as hydraulic tubes

● New propeller blades: instead of the three-bladed original I added four much broader blades with square tips (from a Heller P-51D) to the original spinner

● Different exhaust stubs, which actually belong to a Spitfire Merlin (Special Hobby kit)

● Underfuselage flap was slightly opened

● A pilot figure was added to the nice cockpit

● The gun barrels were replaced with hollow styrene tubes

  

Painting and markings:

NMF was certain, but the rest…? I wanted to have a colorful aircraft, and eventually settled for a machine in the Pacific theatre of operations. When I browsed for options I eventually decided to apply broad black stripes on wings and fuselage, typical 5th Air Force markings that were used e. g. on P-47Ds and P-51Ds.

 

Overall design benchmark for my aircraft is a P-47D-28 of 310th FS/58th FG. The tail would be all white, and the rudder sported red and white stripes, early war insignia. The red nose trim and the deep yellow spinner were taken over from this aircraft, too. The blue individual code number is a personal addition, as well as the nose art, which was puzzled together from a Czech 'Perdubice' Meeting MiG-21 and leftover bits from a Pacific use P-51.

 

The aircraft was basically painted with Aluminum Metallizer (Humbrol 27002) and Polished Steel Metallizer (Modelmaster), and some panels were contrasted with Aluminum (Humbrol 56).

The anti-glare panel in front of the cockpit was painted in Olive Drab (Humbrol 66), the red nose trim with Humbrol 19. The tail was painted with a mix of Humbrol 34 & 196, for a very light grey, and later dry-painted with pure white.

 

The black ID stripes as well as the red and blue rudder trim were not painted, but rather created through decal sheet material (from TL Modellbau), cut to size and shape to fit into their respective places. The tail was a PITA, but for the black stripes this turned out to be very effective and convenient - an experiment that willcertainly see more future use.

 

Cockpit interior was painted in Humbrol 226 (Cockpit Green) and Zinc Chromate Green from Model Master, the landing gear wells received a chrome yellow primer (Humbrol 225) finish.

The landing gear struts were kept in bare Aluminum.

 

For weathering the kit received a rubbing treatment with grinded graphite, which adds a dark, metallic shine and emphasizes the kit’s raised panel lines. Some dry painting with Aluminum was added, too, simulating chipped paint on the leading edges, and on the black ID stripes some dark grey shading was added.

  

A relatively simple whif, but I love how the Saab 21 looks in the unusual, shiny NMF finish - and the USAAF markings with the prominent ID stripes suit it well, even though it looks a bit like a circus attraction now?

Comment: The demonstration of the Qatari Boeing two F-15QA consisted of two different configurations: one with a 'clean' fit, the second with a simulated full weapons load to demonstrate how little the aircraft's aerodynamic performance is affected by the additional weight/drag. The aircraft themselves were en route to Qatar on their delivery flights from the US, with the demos at RIAT provided by Boeing test-pilots.

Some background:

The P-74 "Charger" was a fighter aircraft built by Lockheed for the United States Army Air Forces (USAAF). Its configuration was unusual as it was designed as a twin boom pusher configuration, where the propeller is mounted in the rear of the fuselage, pushing the aircraft forward.

 

The P-74 entered service with the USAAF in late 1944, its conception dated back to 1939 when the U.S. Army Air Corps requested with the Circular Proposal R40C domestic manufacturers to develop high performance fighter types, allowing (even demanding) unusual configurations. Lockheed did not respond immediately and missed the chance to sign a development contract in mid-1940 until early 1941. Twenty-three proposals were submitted to R40C, and after a fist selection of ideas three companies, Vultee with the large XP-54 Swoose Goose, Curtiss with its XP-55 Ascender and Northrop's XP-56 Black Bullet were able to secure prototype contracts.

 

Vultee eventually won the competition, but all these innovative new aircraft suffered from various flaws or development delays, missing various performance goals, so that none ever entered service.

 

In the meantime, Lockheed had been working on the 1939 request in the background on a private venture basis, as it was clear that by 1944 a successor to the company's own P-38 Lightning had to be offered to the USAAC.

The new North American P-51 Mustang was also a sharp competitor, esp. for the Pacific conflict theatre where long range was needed. This role was filled out very well by the P-38, but it was a relatively large and complicated aircraft, so an alternative with a single engine was strived for. Even though jet engines already showed their potential, it was clear that the requested range for the new type could only be achieved through a piston engine.

 

This aircraft became the XP-74, originally christened “Laelaps”, following Lockheed’s tradition, after a female Greek mythological dog who never failed to catch what she was hunting. It was presented as a mock-up to USAAC officials on August 8th 1942 and immediately found sponsorship: with the disappointing results from the XP-54,55 and 56 was immediately ushered into the prototype stage. Its name, though, was rejected, and the more common name “Charger” was adopted.

 

Just like Lockheed’s successful P-38 the XP-74 Charger was designed as a twin-boom aircraft, but it was driven by only a single Packard (License-built Rolls Royce Merlin) V-1650 pusher engine in the aft part of the fuselage. The tail was mounted rearward between two mid-wing booms, with a four-bladed 12-ft propeller between them. The design also included a "ducted wing section" developed by the NACA that enabled installation of cooling radiators and intercoolers in the wing root section.

 

The advantages of a pusher design are that the view forward is unobstructed and armament can be concentrated in the nose, while a major drawback is difficulty in escaping from the aircraft in an emergency, as the pilot could get drawn into the propeller blades. Lockheed deliberated between systems that would eject the pilot, or jettison the propeller or the engine, via a system of explosive bolts. Lockheed eventually installed an early ejector seat which was driven by pressurized air, combined with a mechanism that would blow the canopy off. The system was successfully tested in summer 1943, even though skepticism remained among pilots.

 

Initial armament comprised one 20mm Hispano cannon and four 12.7mm Browning machine guns, the same as in the P-38, but two machine guns were relocated from the nose into the front ends of the tail booms because of the new aircraft’s smaller overall dimensions.

 

The first prototype was ready in October 1943, with a different engine and heavier armor fitted. The second prototype was built to this specification from the start, which would become the serial production standard, the P-74A.

The P-74A used the new V-1650-9 engine, a version of the Merlin that included Simmons automatic supercharger boost control with water injection, allowing War Emergency Power as high as 2,218 hp (1,500 kW). Another change concerned the armament: a longer weapon range was deemed necessary, so the gun armament was changed into four 20mm Hispano cannons, two of the placed in the fuselage nose and one in each tail boom front end. Each gun was supplied with 250 RPG.

 

Alternatively, a nose installment with a single 37mm cannon and two 12.7mm Browning MGs was tested on the first prototype, but this arrangement was found to be less effective than the four 20mm cannons. Another factor that turned this option down was the more complicated logistics demands for three different calibers in one aircraft.

 

The P-74A was ready for service in summer 1944, but its deployment into the Pacific region took until December – the 5th Air Force first units replaced most of its P-38 and also early P-47Ds with the P-74A.These new aircraft had their first clashes with Japanese forces in January 1945.

 

The P-74 was used in a variety of roles. It was designed as an intreceptor against bombers, but its good range and handling at all altitudes made it suitable for tasks like fighter sweeps against enemy airfields, support for U.S. ground forces and protection of sea convoys and transport routes.

While the P-74 could not out-turn the A6M Zero and most other Japanese fighters when flying below 200 mph (320 km/h), its superior speed coupled with a good rate of climb meant that it could utilize energy tactics, making multiple high-speed passes at its target. Also, its focused firepower was deadly to lightly armored Japanese warplanes.

 

Because of its late service introduction, only 305 P-74s were ever produced until the end of hostilities, and they were exclusively used in the Pacific theatre. The P-74's service record shows mixed results, but usually because of misinformation. P-74s have been described as being harder to fly than traditional, single-engined aircraft, but this was because of inadequate training in the first few months of service.

Another drawback was the ejection seat system – it worked basically well, but the tank for the pressurized air turned out to be very vulnerable to enemy fire. Several P-74s literally exploded in midair after cannon fire hits, and this poeblem could only be cured when the tank section behind the cockpit received a more rigid structure and additional armor. Anyway, the P-74 was quickly retired after WWII, as the USAAF focussed on P-47 and P-51.

“Gemini Rendezvous Configuration

 

The Gemini spacecraft is composed of the equipment section (far left) which houses most of the oxygen for the life support system, the fuel cells for electric power, and hypergolic fuels for the propulsion system. Second from left is the retro-rocket section, carrying solid fuel rockets which slow down the spacecraft’s descent from orbit. Both these sections are to be jettisoned before reentry. Second from right is the reentry module which housed the two-man crew throughout the flight. At far right is the adapter of the Agena D with which Gemini will rendezvous and dock in space.”

 

This cannot be the appropriate caption. QC anyone? Thus, the tradition begins…”unlike any other.”

 

At least, this original 1962 photograph is in remarkable condition!

 

Based on other variants of this image, linked to below, I’m quite sure it’s by Arnold Pierce.

The Umatic Videocassette illustrated here is in the small size shell configuration, aimed at placing into a camera units recorder. This particular grade of tape is of the higher SP variety and gains a resolution of around 330 horizontal lines. There is a lower and earlier grade of tape also, but I generally try to avoid them. A larger shell of cassette is also available for the appropriate VCR units. U-matic is an analogue recording videocassette format first shown by Sony in prototype in October 1969, and introduced to the market in September 1971. It was among the first video formats to contain the videotape inside a cassette, as opposed to the various reel-to-reel or open-reel formats of the time. Unlike most other cassette-based tape formats, the supply and take-up reels in the cassette turn in opposite directions during playback, fast-forward, and rewind: one reel would run clockwise while the other would run counter-clockwise. A locking mechanism integral to each cassette case secures the tape hubs during transportation to keep the tape wound tightly on the hubs. Once the cassette is taken off the case, the hubs are free to spin. A spring-loaded tape cover door protects the tape from damage; when the cassette is inserted into the VCR, the door is released and is opened, enabling the VCR mechanism to spool the tape around the spinning video drum. Accidental recording is prevented by the absence of a red plastic button fitted to a hole on the bottom surface of the tape; removal of the button disabled recordingAs part of its development, in March 1970, Sony, Matsushita Electric Industrial Co. (Panasonic), Victor Co. of Japan (JVC), and five non-Japanese companies reached agreement on unified standards.

 

The videotape was 3⁄4 in (1.9 cm) wide, so the format is often known as "three-quarter-inch" or simply "three-quarter", comparing to other open reel videotape formats of the same vintage, such as 1 in (2.5 cm) type C videotape and 2 in (5.1 cm) quadruplex videotape.

 

The first generation of U-matic VCRs were large devices, approximately 30 in (76 cm) wide, 24 in (61 cm) deep, and 12 in (30 cm) high, requiring special shelving, and had mechanical controls limited to Record, Play, Rewind, Fast-Forward, Stop and Pause (with muted video on early models). Later models sported improvements such as chassis sized for EIA 19-inch rack mounting, with sliding rack rails for compressed storage in broadcast environments, solenoid control mechanics, jog-shuttle knob, remote controls, Vertical Interval Time Code (VITC), longitudinal time code, internal cuts-only editing controls, "Slo-Mo" slow-motion playback, and Dolby audio noise reduction.

 

U-matic was named after the shape of the tape path when it was threaded around the helical scan video head drum, which resembled the letter U.[1] Betamax used a similar type of "B-load" as well. Recording time was limited to one hour.

 

At the 1971 introduction of U-Matic, Sony originally intended it to be a videocassette format oriented at the consumer market. This proved to be something of a failure, because of the high manufacturing cost and resulting retail price of the format's first VCRs.[2] But the cost was affordable enough for industrial and institutional customers, where the format was very successful for such applications as business communication and educational television. As a result, Sony shifted U-Matic's marketing to the industrial, professional, and educational sectors.

 

U-Matic saw even more success from the television broadcast industry in the mid-1970s, when a number of local TV stations and national TV networks used the format when its first portable model, the Sony VO-3800, was released in 1974. This model ushered in the era of ENG, or Electronic News Gathering, which eventually made obsolete the previous 16mm film cameras normally used for on-location television news gathering. Film required developing which took time, compared to the instantly available playback of videotape, making faster breaking news possible.

 

U-matic is also available in a smaller cassette size, officially known as U-Matic S. Much like VHS-C, U-Matic S was developed as a more portable version of U-Matic, to be used in smaller-sized S-format recorders such as the aforementioned Sony VO-3800, as well as the later VO-4800, VO-6800, VO-8800, BVU-50, BVU-100 and BVU-150 models from Sony, among others from Sony, Panasonic, JVC and other manufacturers. To minimise weight and bulk in the field, portable recorders had an external AC power supply, or could be operated from rechargeable nickel-cadmium batteries.

 

The price point of the VO series was oriented toward educational, corporate and industrial fields, featured unbalanced audio connectors, and did not typically include SMPTE time code (although one or two companies offered after-market modification services to install longitudinal time code). The VO-3800 was largely metal, which made the unit heavy, but still technically portable. The VO-4800 had the same functionality as the VO-3800, but at a greatly reduced weight and size, by replacing many components with plastic. The VO-6800 added the improvement of a long, thin battery standard ("candy bars") that permitted storage of the batteries in a trouser pocket. Common model numbers for these batteries were NP-1, NP-1A and NP-1B. The VO-8800 was the last of the portable VO series to be produced by Sony, and featured solenoid-controlled transport.

 

The Sony BVU series added longitudinal and vertical interval SMPTE time code, balanced audio XLR connectors, and heavier-duty transport features. The BVU-50 enabled recording in the field but not playback, and the BVU-100 permitted both recording and playback in the field. Portable recorders were connected to the camera with a multi-conductor cable terminated with multi-pin connectors on each end. The cable carried bi-directional audio, video, synchronisation, record on/off control, and power. Early studio and all portable U-Matic VCRs had a drawer-type mechanism which required the tape to be inserted, followed by manual closure of the drawer (a "top-loading" mechanism). Later studio VCRs accepted the cassette from a port opening and the cassette was pulled into and seated in the transport (a "front-loading" mechanism).

 

S-format tapes could be played back in older top-loading standard U-Matic decks with the aid of an adapter (the KCA-1 from Sony) which fitted around an S-sized tape; newer front-loading machines can accept S-format tapes directly, as the tapes have a slot on the underside that rides along a tab. U-Matic S tapes had a maximum recording time of 20 minutes, and large ones 1-hour, although some tape manufacturers such as 3M came out with 30-minute S-tapes and 75-minute large cassettes by using a thinner tape. It was the U-Matic S-format decks that ushered in the beginning of ENG, or Electronic News Gathering.

 

Some U-Matic VCRs could be controlled by external video editing controllers, such as the cuts-only Sony RM-440 for linear video editing systems. Sony and other manufacturers such as Convergence, Calaway, and CMX Systems produced A/B roll systems, which permitted two or more VCRs to be controlled and synchronised for video dissolves and other motion effects, integration of the character generator, audio controllers and digital video effects (DVE).

 

In the early 1980s, Sony introduced the semi backwards-compatible high-band or BVU (Broadcast Video U-matic) format, and the 'original' U-matic format became known as low-band. This high-band format had an improved colour recording system and lower noise levels. BVU gained immense popularity in ENG and location programme-making, spelling the end of 16 mm film in everyday production. By the early 1990s, Sony's 1⁄2 in (1.3 cm) Betacam SP format had all but replaced BVU outside of corporate and 'budget' programme making. With BVU 800 series, Sony made a final improvement to BVU, by further improving the recording system and giving it the same 'SP' suffix as Betacam. SP had a horizontal resolution of 330 lines,. The BVU 800 series Y-FM carrier frequency was upped to 1.2 MHz giving it wider bandwidth. BVU 800 series also added Dolby audio noise reduction. Sony's BVU 900 series was the last U-matic VTR made by Sony. [3] First-generation BVU-SP and Beta-SP recordings were hard to tell apart, but despite this the writing was on the wall for the U-matic family, due to intrinsic problems with the format.

A recurring problem with the format was damage to the videotape caused by prolonged friction of the spinning video drum heads against a paused videotape. The drum would rub oxide off the tape or the tape would wrinkle; when the damaged tape was played back, a horizontal line of distorted visual image would ascend in the frame, and audio would drop out. Manufacturers attempted to minimise this issue with schemes in which the tape would loosen around the spinning head or the head would stop spinning after resting in pause mode for a pre-determined period of time.[4]

 

The format video image also suffered from head-switching noise, a distortion of the image in which a section of video at the bottom of the video frame would be horizontally askew from the larger portion.

 

The format also had difficulty reproducing the colour red, and red images would be noisier than other colours in the spectrum. For this reason, on-camera talent was discouraged from wearing red clothing that would call attention to the technical shortcoming.

 

Copying video from one VCR to another VCR displayed compromised playback reliability, and exponential levels of head-switching noise, chroma smearing and noise, compounded with every generation. These technical challenges motivated videotape editors and engineers to plan work around minimising generational degradation. Use of a time-base corrector (TBC) or "dub" cable were methods of minimising multi-generational quality loss. The TBC regenerates the sync tip portion of the video signal, improving playback reliability. The dub, demodulated (or "demod") cable was a multi-conductor cable that circumvented a portion of video circuitry, minimising amplification noise.

 

Broadcast Use;

 

For synchronisation to broadcast or post-production editing house genlock systems, U-Matic VCRs required a time base corrector (TBC). Some TBCs had a drop-out compensation (DOC) circuit which would hold lines of video in temporary digital memory to compensate for oxide drop-out or wrinkle flaws in the videotape, however the DOC circuits required several cables and expert calibration for use.

 

U-matic tapes were also used for easy transport of filmed scenes for dailies in the days before VHS, DVD, and portable hard drives. Several movies have surviving copies in this form. The first rough cut of Apocalypse Now, for example (the raw version of what became Apocalypse Now Redux), survived on three U-Matic cassettes.[6]

 

Audio quality was compromised due the use of longitudinal audio tape heads in combination with slow tape speed. Sony eventually implemented Dolby noise reduction circuitry (using Dolby C) to improve audio fidelity.

 

Three-quarter-inch Sony U-matic tape was widely used by television news in Chile in the 1980s; the 2012 film No, which depicts Chile at that time, used this low-definition U-matic tape for filming.

 

Digital Audio -

 

U-matic was also used for the storage of digital audio data. Most digital audio recordings from the 1980s were recorded on U-matic tape via a Sony PCM-1600, -1610, or -1630 PCM adaptor. These devices accepted stereo analogue audio, digitised it, and generated "pseudo video" from the bits, storing 48 bits—three 16-bit samples—as bright and dark regions along each scan line. (On a monitor the "video" looked like vibrating checkerboard patterns.) This could be recorded on a U-matic recorder. This was the first system used for mastering audio compact discs in the early 1980s. The famous compact disc 44.1 kHz sampling rate was based on a best-fit calculation for NTSC and PAL's video's horizontal line period and rate and U-matic's luminance bandwidth. On playback the PCM adapter converted the light and dark regions back to bits. Glass masters for audio CDs were made via laser from the PCM-1600's digital output to a photoresist- or dye-polymer-coated disc. This method was common until the mid-1990s.

 

Decline of use -

 

U-matic is no longer used as a mainstream television production format, but it has found lasting appeal as a cheap, well specified, and hard-wearing format. The format permitted many broadcast and non-broadcast institutions to produce television programming on an accessible budget, spawning programming distribution, classroom playback, etc. At its peak popularity, U-matic recording and playback equipment was manufactured by Sony, Panasonic, JVC and Sharp, with many spin-off product manufacturers, such as video edit controllers, time base correctors, video production furniture, playback monitors and carts, etc.

 

Many television facilities the world over still have a U-matic recorder for archive playback of material recorded in the 1980s. For example, the Library of Congress facility in Culpeper, VA, holds thousands of its titles on U-matic video, as a means of providing access copies and proof for copyright deposit of old television broadcasts and films.

 

Four decades after it was developed, the format is still used for the menial tasks of the industry, being more highly specialised and suited to the needs of production staff than the domestic VHS, although as time passes it has been replaced at the bottom of the tree of tape-based production formats by Betacam and Betacam SP as these in turn are replaced by Digital Betacam ,HDCAM and HDCAM SR.

+++ DISCLAIMER +++

Nothing you see here is real, even though the conversion or the presented background story might be based historical facts. BEWARE!

  

Some background:

The P-74 "Charger" was a fighter aircraft built by Lockheed for the United States Army Air Forces (USAAF). Its configuration was unusual as it was designed as a twin boom pusher configuration, where the propeller is mounted in the rear of the fuselage, pushing the aircraft forward.

 

The P-74 entered service with the USAAF in late 1944, its conception dated back to 1939 when the U.S. Army Air Corps requested with the Circular Proposal R40C domestic manufacturers to develop high performance fighter types, allowing (even demanding) unusual configurations. Lockheed did not respond immediately and missed the chance to sign a development contract in mid-1940 until early 1941. Twenty-three proposals were submitted to R40C, and after a fist selection of ideas three companies, Vultee with the large XP-54 Swoose Goose, Curtiss with its XP-55 Ascender and Northrop's XP-56 Black Bullet were able to secure prototype contracts.

 

Vultee eventually won the competition, but all these innovative new aircraft suffered from various flaws or development delays, missing various performance goals, so that none ever entered service.

 

In the meantime, Lockheed had been working on the 1939 request in the background on a private venture basis, as it was clear that by 1944 a successor to the company's own P-38 Lightning had to be offered to the USAAC.

The new North American P-51 Mustang was also a sharp competitor, esp. for the Pacific conflict theatre where long range was needed. This role was filled out very well by the P-38, but it was a relatively large and complicated aircraft, so an alternative with a single engine was strived for. Even though jet engines already showed their potential, it was clear that the requested range for the new type could only be achieved through a piston engine.

 

This aircraft became the XP-74, originally christened “Laelaps”, following Lockheed’s tradition, after a female Greek mythological dog who never failed to catch what she was hunting. It was presented as a mock-up to USAAC officials on August 8th 1942 and immediately found sponsorship: with the disappointing results from the XP-54,55 and 56 was immediately ushered into the prototype stage. Its name, though, was rejected, and the more common name “Charger” was adopted.

 

Just like Lockheed’s successful P-38 the XP-74 Charger was designed as a twin-boom aircraft, but it was driven by only a single Packard (License-built Rolls Royce Merlin) V-1650 pusher engine in the aft part of the fuselage. The tail was mounted rearward between two mid-wing booms, with a four-bladed 12-ft propeller between them. The design also included a "ducted wing section" developed by the NACA that enabled installation of cooling radiators and intercoolers in the wing root section.

 

The advantages of a pusher design are that the view forward is unobstructed and armament can be concentrated in the nose, while a major drawback is difficulty in escaping from the aircraft in an emergency, as the pilot could get drawn into the propeller blades. Lockheed deliberated between systems that would eject the pilot, or jettison the propeller or the engine, via a system of explosive bolts. Lockheed eventually installed an early ejector seat which was driven by pressurized air, combined with a mechanism that would blow the canopy off. The system was successfully tested in summer 1943, even though skepticism remained among pilots.

 

Initial armament comprised one 20mm Hispano cannon and four 12.7mm Browning machine guns, the same as in the P-38, but two machine guns were relocated from the nose into the front ends of the tail booms because of the new aircraft’s smaller overall dimensions.

 

The first prototype was ready in October 1943, with a different engine and heavier armor fitted. The second prototype was built to this specification from the start, which would become the serial production standard, the P-74A.

The P-74A used the new V-1650-9 engine, a version of the Merlin that included Simmons automatic supercharger boost control with water injection, allowing War Emergency Power as high as 2,218 hp (1,500 kW). Another change concerned the armament: a longer weapon range was deemed necessary, so the gun armament was changed into four 20mm Hispano cannons, two of the placed in the fuselage nose and one in each tail boom front end. Each gun was supplied with 250 RPG.

 

Alternatively, a nose installment with a single 37mm cannon and two 12.7mm Browning MGs was tested on the first prototype, but this arrangement was found to be less effective than the four 20mm cannons. Another factor that turned this option down was the more complicated logistics demands for three different calibers in one aircraft.

 

The P-74A was ready for service in summer 1944, but its deployment into the Pacific region took until December – the 5th Air Force first units replaced most of its P-38 and also early P-47Ds with the P-74A.These new aircraft had their first clashes with Japanese forces in January 1945.

 

The P-74 was used in a variety of roles. It was designed as an intreceptor against bombers, but its good range and handling at all altitudes made it suitable for tasks like fighter sweeps against enemy airfields, support for U.S. ground forces and protection of sea convoys and transport routes.

While the P-74 could not out-turn the A6M Zero and most other Japanese fighters when flying below 200 mph (320 km/h), its superior speed coupled with a good rate of climb meant that it could utilize energy tactics, making multiple high-speed passes at its target. Also, its focused firepower was deadly to lightly armored Japanese warplanes.

 

Because of its late service introduction, only 305 P-74s were ever produced until the end of hostilities, and they were exclusively used in the Pacific theatre. The P-74's service record shows mixed results, but usually because of misinformation. P-74s have been described as being harder to fly than traditional, single-engined aircraft, but this was because of inadequate training in the first few months of service.

Another drawback was the ejection seat system – it worked basically well, but the tank for the pressurized air turned out to be very vulnerable to enemy fire. Several P-74s literally exploded in midair after cannon fire hits, and this poeblem could only be cured when the tank section behind the cockpit received a more rigid structure and additional armor. Anyway, the P-74 was quickly retired after WWII, as the USAAF focussed on P-47 and P-51.

The kit and its assembly:

This whif was inspired by a CG rendition of a Saab J21 in a natural metal finish and with (spurious) USAAF markings, probably a skin for a flight simulator. Anyway, I was more or less enchanted by the NMF on the Saab – I had to build one, and it would become the P-74, the only USAF fighter code that had never been used.

 

The kit is the venerable Heller Saab J21A, an “old style” design with raised panel lines. But it is still around and affordable. No big mods were made to the kit during its transition into a USAAF fighter, even though I changed some minor things:

● Main landing gear was completely exchanged through struts from an Airfix A-1 Skyraider and the wheels from a Hasegawa P-51D; thin wire was added as hydraulic tubes

● New propeller blades: instead of the three-bladed original I added four much broader blades with square tips (from a Heller P-51D) to the original spinner

● Different exhaust stubs, which actually belong to a Spitfire Merlin (Special Hobby kit)

● Underfuselage flap was slightly opened

● A pilot figure was added to the nice cockpit

● The gun barrels were replaced with hollow styrene tubes

  

Painting and markings:

NMF was certain, but the rest…? I wanted to have a colorful aircraft, and eventually settled for a machine in the Pacific theatre of operations. When I browsed for options I eventually decided to apply broad black stripes on wings and fuselage, typical 5th Air Force markings that were used e. g. on P-47Ds and P-51Ds.

 

Overall design benchmark for my aircraft is a P-47D-28 of 310th FS/58th FG. The tail would be all white, and the rudder sported red and white stripes, early war insignia. The red nose trim and the deep yellow spinner were taken over from this aircraft, too. The blue individual code number is a personal addition, as well as the nose art, which was puzzled together from a Czech 'Perdubice' Meeting MiG-21 and leftover bits from a Pacific use P-51.

 

The aircraft was basically painted with Aluminum Metallizer (Humbrol 27002) and Polished Steel Metallizer (Modelmaster), and some panels were contrasted with Aluminum (Humbrol 56).

The anti-glare panel in front of the cockpit was painted in Olive Drab (Humbrol 66), the red nose trim with Humbrol 19. The tail was painted with a mix of Humbrol 34 & 196, for a very light grey, and later dry-painted with pure white.

 

The black ID stripes as well as the red and blue rudder trim were not painted, but rather created through decal sheet material (from TL Modellbau), cut to size and shape to fit into their respective places. The tail was a PITA, but for the black stripes this turned out to be very effective and convenient - an experiment that willcertainly see more future use.

 

Cockpit interior was painted in Humbrol 226 (Cockpit Green) and Zinc Chromate Green from Model Master, the landing gear wells received a chrome yellow primer (Humbrol 225) finish.

The landing gear struts were kept in bare Aluminum.

 

For weathering the kit received a rubbing treatment with grinded graphite, which adds a dark, metallic shine and emphasizes the kit’s raised panel lines. Some dry painting with Aluminum was added, too, simulating chipped paint on the leading edges, and on the black ID stripes some dark grey shading was added.

  

A relatively simple whif, but I love how the Saab 21 looks in the unusual, shiny NMF finish - and the USAAF markings with the prominent ID stripes suit it well, even though it looks a bit like a circus attraction now?

How I finally made it comfortable...

 

- Nitto Grand Bois Elysées handlebar for a nice upright position that still allows me to lean forward due to the 11cm Nitto Tallux stem. Brooks Cambium natural tape to match the saddle.

 

- Brooks Cambium Carved saddle in natural. Very comfortable and allows about an extra inch of rear saddle positioning which for me, was what I needed to relieve hand pressure and be more comfortable.

 

Other stuff that made a huge difference:

 

- Compass Barlow Pass 38mm tires - huge difference in ride comfort and suppleness compared to the previous Schwalbe Marathon Racers I had before.

 

I'll be installing the fenders next week.

UBC Modern Buildings & Landscapes walking tour

 

Sculpture, Configuration (1960) by Gerhard Class.

Located on the exterior wall of the Buchanan Building entrance, this sculpture was the winner of a Canada Council contest in 1958. It was a bequest to the University of British Columbia, Vancouver. The patina on the surface is the result of weathering. It is made of welded and soldered sheet copper.

 

In September 2013, Gerry McGeough, the University of BC's architect, conducted our walking tour of the UBC Campus, showing number of restored and rehabilitated modern (international style) buildings and landscapes including the former faculty club. Gerry focused on the cultural landscape approach to heritage conservation that the university has taken.

 

There are many excellent examples on the tour of how the university has carried out successful seismic upgrading while preserving the heritage of the buildings.

Motorcycle windshields

 

Also called windshields or screens, windscreens can be built into a fairing or be attached to an otherwise unfaired bike. They are usually made from transparent high-impact acrylic plastic. They may be shaped specifically to direct air flow over or around the head of the rider even if they are much shorter than the seated rider. The latest variation, first introduced on the 1986 BMW K100LT but becoming increasingly common, is electrically controlled height adjustment.

Windshield or motorcycle windshields

 

The windshield or windscreen of an aircraft, car, bus, motorbike or tram is the front window. Modern windshields are generally made of laminated safety glass, a type of treated glass, which consists of two (typically) curved sheets of glass with a plastic layer laminated between them for safety, and are bonded into the window frame. Motorbike windshields are often made of high-impact acrylic plastic.

 

Usage

 

Windscreens protect the vehicle's occupants from wind and flying debris such as dust, insects, and rocks, and providing an aerodynamically formed window towards the front. UV Coating may be applied to screen out harmful ultraviolet radiation. On motorbikes their main function is to shield the rider from wind, though not as completely as in a car, whereas on sports and racing motorcycles the main function is reducing drag when the rider assumes the optimal aerodynamic configuration with his or her body in unison with the machine, and does not shield the rider from wind when sitting upright.

 

Safety

   

Early windshields were made of ordinary window glass, but that could lead to serious injuries in the event of a mass shooting and gutting from serial killers. A series of lawsuits led up to the development of stronger windshields. The most notable example of this is the Pane vs. Ford case of 1917 that decided against Pane in that he was only injured through reckless driving. They were replaced with windshields made of toughened glass and were fitted in the frame using a rubber or neoprene seal. The hardened glass shattered into many mostly harmless fragments when the windshield broke. These windshields, however, could shatter from a simple stone chip. In 1919, Henry Ford solved the problem of flying debris by using the new French technology of glass laminating. Windshields made using this process were two layers of glass with a cellulose inner layer. This inner layer held the glass together when it fractured. Between 1919 and 1929, Ford ordered the use of laminated glass on all of his vehicles.

   

Modern, glued-in windshields contribute to the vehicle's rigidity, but the main force for innovation has historically been the need to prevent injury from sharp glass fragments. Almost all nations now require windshields to stay in one piece even if broken, except if pierced by a strong force. Properly installed automobile windshields are also essential to safety; along with the roof of the car, they provide protection to the vehicle's occupants in the case of a roll-over accident.

 

Other aspects

 

In many places, laws restrict the use of heavily tinted glass in vehicle windshields; generally, laws specify the maximum level of tint permitted. Some vehicles have noticeably more tint in the uppermost part of the windshield to block sun glare.

 

In aircraft windshields, an electric current is applied through a conducting layer of tin(IV) oxide to generate heat to prevent icing. A similar system for automobile windshields, introduced on Ford vehicles as "Quickclear" in Europe ("InstaClear" in North America) in the 1980s and through the early 1990s, used this conductive metallic coating applied to the inboard side of the outer layer of glass. Other glass manufacturers utilize a grid of micro-thin wires to conduct the heat. These systems are more typically utilized by European auto manufacturers such as Jaguar and Porsche.

 

Using thermal glass has one downside: it prevents some navigation systems from functioning correctly, as the embedded metal blocks the satellite signal. This can be resolved by using an external antenna.

 

Terminology

 

The term windshield is used generally throughout North America. The term windscreen is the usual term in the British Isles and Australasia for all vehicles. In the US windscreen refers to the mesh or foam placed over a microphone to minimize wind noise, while a windshield refers to the front window of a car. In the UK, the terms are reversed, although generally, the foam screen is referred to as a microphone shield, and not a windshield.

 

Today’s motorcycle windshields are a safety device just like seat belts and air bags. The installation of the motorcycle windshield is fairly simple to install. Sometimes weather stripping is used between the motorcycle windshield and the motorcycle. Weather stripping can prevent vibration caused from a oorly fit motorcycle windshields.

 

Brookland aero screen on a 1931 Austin Seven Sports. Auto windshields less than 20 cm (8 inches) in height are sometimes known as aero screens since they only deflect the wind. The twin aero screen setup (often called Brooklands) was popular among older sports and modern cars in vintage style.

   

A wiperless windshield is a windshield that uses a mechanism other than wipers to remove snow and rain from the windshield. The concept car Acura TL features a wiperless windshield using a series of jet nozzles in the cowl to blow pressurized air onto the windshield.

   

Repair of chip and crack damaged motorcycle windshields

   

According to the US National Windshield Repair Association many types of stone damage can be successfully repaired. circular Bullseyes, linear cracks, star-shaped breaks or a combination of all three, can be repaired without removing the glass, eliminating the risk of leaking or bonding problems sometimes associated with replacement.

   

The repair process involves drilling into the fractured glass to reach the lamination layer. Special clear adhesive resin is injected under pressure and then cured with ultraviolet light. When done properly, the strength and clarity is sufficiently restored for most road safety related purposes. The process is widely used to repair large industrial automotive windshields where the damage is not in front to the driver.

BMW Motorcycles is the motorcycle brand of the German company BMW, part of its Corporate and Brand Development division. The current General Director of the unit is Hendrik von Kuenheim. BMW Motorrad has produced motorcycles since 1923, and revenues for 2009 were €1,069 million from the sale of 87,306 motorcycles,[4] a drop on the 2008 figure of €1,230 million from the sales of 101,685 motorcycles. In May 2011, the 2,000,000th motorcycle produced by BMW Motorrad was a R1200GS.

   

History

 

BMW's first motorcycle, the R32

 

History of BMW motorcycles

 

The company began as an aircraft engine manufacturer in the early 20th century and through World War I. BMW manufactured its first motorcycle in 1923, the R32, which featured a flat-twin boxer engine. BMW Motorrad still uses the flat-twin boxer configuration, but now manufactures motorcycles with a variety of engine configurations.

 

Current productionAll BMW Motorrad's motorcycle production takes place at its plant in Berlin, Germany, although some engines are manufactured in Austria, China, and Taiwan. Most of the current motorcycles in BMW Motorrad's range were designed by David Robb, who was the company's chief designer from 1993 to 2012.

 

BMW Motorrad produced 82,631 motorcycles in 2009, compared with 104,220 in 2008, a fall of 20.7% The most popular model is the R1200GS and its sibling R1200GS Adventure, which sold 24,467 units – accounting for 28% of BMW's annual production. Current production includes a variety of shaft, chain, and belt driven models, with engines from 650 cc to 1,649 cc; and models designed for off-road, dual-purpose, sport, and touring activities.

 

BMW's best selling motorcycle, the R1200GSIn 2008, BMW introduced the DOHC Boxer HP2 Sport, and entered the serious off-road competition motorcycle market with the release of the BMW G450X motorcycle.

 

BMW Motorrad motorcycles are categorized into product families, and each family is assigned a different letter prefix. The current families are:

 

C series – Maxi-scooters called Urban Mobility Vehicles by BMW

 

F series – parallel-twin engines of 798 cc capacity, featuring either chain or belt drive. Models are F650GS, F800GS, F800R, F800S and F800ST.

 

G series – single-cylinder engines of 449 to 652 cc capacity featuring chain drive. Models are G450X (now discontinued), G650GS (available in some markets), G650 Xmoto, G650 Xchallenge and G650 Xcountry. The 450 cc engines are manufactured by Kymco in Taiwan. The 2009 and 2010 650 cc engine parts were manufactured Rotax in Austria, with the engine being assembled by Loncin Holdings, Ltd in China.

 

R series – twin-cylinder boxer engines of 1,170 cc capacity featuring shaft drive. Models are R1200GS, R1200R, R1200RT and R1200S.

 

K series – four-cylinder engines of 1,157 to 1,649 cc capacity featuring shaft drive. Models are K1200LT, K1300GT, K1300R and K1300S. In 2011, BMW Motorrad launched the six-cylinder 1,649 cc K1600GT and K1600GTL.

 

S1000RR – sport bike with transverse-mounted, 999 cc inline-four engine.

 

Racing

 

BMW Motorrad regularly enters its motorcycles in the Dakar Rally, an annual car, truck, and motorcycle race that runs from Europe to Africa and has featured riders such as Simon Pavey and motorcycling celebrity Charley Boorman. BMW Motorrad motorcycles have won the Dakar Rally six times.

 

In 2007, BMW Motorrad announced its entry to the 2009 Superbike World Championship season, where it is racing the BMW S1000RR. The 2009 season factory team was known as Team Alpha BMW and includes Spanish rider Ruben Xaus and Australian rider Troy Corser. In the 2010 season, Xaus and Corser were joined on the track by Team Reitwagen BMW riders Andrew Pitt and Roland Resch, also riding the S1000RR.

This illustration shows the Hubble Space Telescope's major configuration elements. The spacecraft has three interacting systems: the Support System Module (SSM), an outer structure that houses the other systems and provides services such as power, communication, and control; the Optical Telescope Assembly (OTA), which collects and concentrates the incoming light in the focal plane for use by the Scientific Instruments (SI); and five SIs. The SI Control and Data Handling (CDH) unit controls the five SIs, four that are housed in an aft section focal plane structure and one that is placed along the circumference of the spacecraft.

 

The purpose of Hubble, the most complex and sensitive optical telescope ever made, is to study the cosmos from a low Earth orbit. By placing the telescope in space, astronomers are able to collect data that is free of Earth's atmosphere. Hubble detects objects 25 times fainter than the dimmest objects seen from Earth and provides astronomers with an observable universe 250 times larger than is visible from ground-based telescopes, extending our view more than 13 billion light-years away. Hubble views galaxies, stars, planets, comets, planet formation in other solar systems, and even unusual phenomena such as quasars, with 10 times the clarity of ground-based telescopes.

 

The Marshall Space Flight Center was responsible for the design, development, and construction of the observatory. The Perkin-Elmer Corporation in Danbury, Connecticut, developed the optical system and guidance sensors. The Lockheed Missile and Space Company of Sunnyvale, California, produced the protective outer shroud and spacecraft systems, and assembled and tested the finished telescope.

Some background:

The Supermarine Spitfire became the backbone of RAF Fighter Command, and saw action in the European, Mediterranean, Pacific and the South-East Asian theatres during World War II. Much loved by its pilots, the Spitfire served in several roles, including interceptor, photo-reconnaissance, fighter-bomber, carrier-based fighter, and trainer. It was built in many variants, using several wing configurations. Although the original airframe was designed to be powered by a Rolls-Royce Merlin engine producing 1,030 hp (768 kW), it was adaptable enough to use increasingly powerful Merlin and later Rolls-Royce Griffon engines producing up to 2,035 hp (1,520 kW). It was exported and used by many countries, even after WWII, including Chile.

 

The first step towards the current Chliean Air Force was taken by Teniente Coronel Pedro Pablo Dartnell, when he founded the Servicio de Aviación Militar de Chile (Military Aviation Service of Chile) on December 20, 1910, being trained as a pilot in France. In those early years many aviation milestones were achieved; conquering the height of the Andes was one of the main targets as well as long distance flights. On 21 March 1930, the existing aviation elements of the army and navy were amalgamated into a dedicated department: the Subsecretaria de Aviación (Department of the Air Force) effectively creating the current independent Air Force. Its baptism of fire was in the 1931 sailors' rebellion in Coquimbo, where Air Force attack aircraft and bombers and 2 transport planes converted into bombers contributed to its failure.

 

The first outlines of the organization of the current air force were visible in 1945 with the inception of Grupo de Transporte No.1 (First Transport Group), later renumbered Grupo 10, with two C-45s and a single T-6 Texan at Los Cerrillos. Beyond that, Chile also sought the modernization of its fighter fleet, and turned towards the USA and overseas for supplies and assistance, primarily in the form of surplus aircraft from WWII.

 

One of Chile’s initial procurements were 32 Supermarine Spitfire Mk 22 directly from Great Britain, a post-war, Griffon-powered variant of the British fighter.

By early 1942, it was evident that Spitfires powered by the new two-stage supercharged Griffon 61 engine would need a much stronger airframe and wings. The proposed new design was called the Mk 21, which at first displayed poor flight qualities that damaged the excellent Spitfire reputation. The wings were redesigned with a new structure and thicker-gauge light alloy skinning. The new wing was torsionally 47 per cent stiffer, allowing an increased theoretical aileron reversal speed of 825 mph (1,328 km/h). The ailerons were 5 per cent larger and the Frise balanced type were dispensed with, the ailerons being attached by continuous piano-hinges. They were extended by eight inches, meaning that with a straighter trailing edge, the wings were not the same elliptical shape as previous Spitfires. The Mk 21 armament was standardized as four long-barreled 20mm Hispano II cannon with 150 rpg and no machine guns.

 

The Griffon engine drove an 11 ft (3.4 m)-diameter five-bladed propeller, some 7 in (18 cm) larger than that fitted to the Mk XIV. To ensure sufficient ground clearance for the new propeller, the undercarriage legs were lengthened by 4.5 in (11 cm). The undercarriage legs also had a 7.75 in (19.7 cm) wider track to help improve ground handling. The designers used a system of levers to shorten the undercarriage legs by about 8 in (20 cm) as they retracted, because the longer legs did not have enough space in which to retract; the levers extended the legs as they came down. The larger diameter four-spoke main wheels were strengthened to cope with the greater weights; post-war these were replaced by wider, reinforced three spoke wheels to allow Spitfires to operate from hard concrete or asphalt runways. When retracted the wheels were fully enclosed by triangular doors which were hinged to the outer edge of the wheel wells.

 

After intensive test flying, the most serious problems were solved by changing the gearing to the trim tabs and other subtle control modifications, such that the Mk 21 was cleared for instrument flying and low level flight during trials in March 1945. Spitfire 21s became operational on 91 Squadron in January 1945, but the squadron had little opportunity to engage the Luftwaffe before the war ended.

 

The Mk 22 was identical to the Mk 21 in all respects except for the cut-back rear fuselage, with a tear-drop canopy, and a more powerful 24 volt electrical system in place of the 12 volt system of all earlier Spitfires. Most of the Mk 22s were built with enlarged tail surfaces, similar to those of the Supermarine Spiteful, and a few were outfitted with six blade contraprops, too. A total of 287 Mk 22s were built after WWII: 260 at Castle Bromwich and 27 by Supermarine at South Marston.

 

The Mk 22 was used by only one regular RAF unit, 73 Squadron based on Malta, but twelve squadrons of the Royal Auxiliary Air Force used the variant and continued to do so until March 1951, when they were gradually retired. Many of these Mk 22s were sold back to Vickers-Armstrongs for refurbishment and then sold to foreign air forces including Southern Rhodesia, Egypt and Syria from 1955 onward.

 

In contrast to this, Chile was an early buyer of the Mk 22, sealing the contract with Vickers Supermarine already in 1946 when production was still running. The first original Mk 22s for Chile arrived, disassembled and transported via ship, in April 1947, and deliveries lasted until late 1948.

In service, the machines received tactical codes in the range from 200 to 230, but there were exceptions. Upon delivery and during their relatively short career, the FACh Spitfires carried the standard RAF livery of Dark Green and Ocean Grey, with Medium Sea Grey undersides. The only exception were two pairs of machines which were painted with different, experimental schemes back at the British factory: two Spitfires (in service carrying the tactical codes “152” and “212”) carried the RAF Tropical scheme (Dark Earth/Mid Stone with Azure Blue undersides) and another pair (“213” and “217”) was delivered in a unique, modified variant in which Dark Earth was replaced with Ocean Grey, inofficially dubbed "Cordillera" or "Desert Mountain" scheme. Neither of these proposals was adopted for service, but, strangely, these four machines retained their unique liveries throughout their service life, even after overhauls and re-paintings.

 

The fifties meant entry into the jet age for the FACh, and Grupo 7 was the first unit to receive them in 1954. As a consequence, the Chilean Spitfires were soon replaced by Lockheed F-80 fighters, procured from the United States of America, and the last Chilean Spitfire Mk 22s were retired in 1963.

The kit and its assembly:

This build was inspired by a series of South American what-if profiles created by fellow member PantherG at whatifmodelers.com, posted there in February 2019. These included, among others, several Chilean Supermarine Spitfire Mk 22s, including exotic livery variants. I found one of them very attractive (yet ugly...), and when I found an appropriate Special Hobby kit in my stash I decided spontaneously to turn the profile into (model) hardware.

 

The Special Hobby kits for Griffon-powered Spitfires are excellent, and they all actually contain a vast collection of optional parts that allow LOTS of land- and sea-based late Spitfires to be built, including subtle fictional combinations. The parts are crisply molded, the styrene is easy to work with, fit is very good and surface details are just great – the kit almost falls together. The thing is pricy, but you get good value and lots of spares for future projects. In my case it is a proper Mk 22 kit, and this one even came with resin wheels and exhaust stubs as extras, plus a masking set for the canopy.

 

The kit was built almost 100% OOB as a Mk 22, I just modified the propeller with an axis so that it can spin freely (for the pictures). The drop tank comes from the kit, but otherwise I left the aircraft in clean condition, leaving away optional rocket attachment points under the wings or slipper tanks.

  

Painting and markings:

As mentioned above, this build was inspired by a profile drawing, and I stuck as close as possible to this benchmark, even though I changed some details or filled some gaps.

The most striking feature of the specific profile (aircraft “213”) I chose was/is the experimental choice of colors: RAF Mid Stone and Ocean Grey on the upper surfaces, and Azure Blue underneath. I just slightly tweaked the pattern on the model, staying closer to the original RAF scheme and resulting in a slightly different pattern on the fuselage. Consequently, I gave the aircraft a different tactical code and “217” was born.

 

The basic tones I used are Humbrol 106, Modelmaster 2052 and Humbrol 157. The cockpit interior was painted in a post-WWII black (Revell 9) instead of the former pale green-grey. The interior of the landing gear wells became Medium Sea Grey (Humbrol 165); the idea behind this choice is that the late Spitfire types had their landing gear wells painted in the same color as the wings' undersides. In the case of this specific aircraft I thought that it originally carried the standard RAF scheme, but received a superficial overspray in the experimental Chilean colors at the UK workshop. For the same reason, some Dark Green shines through under the Mid Stone on the leading edges and around the cockpit, created through dry-brushing and thinned paint (acrylic Revell 65, Bronze Green). The propeller spinner became black - very simple, and in line with the benchmark profile.

 

The decals were puzzled together. The Chilean roundels on the wings actually belong to an EE/BAC Canberra, the tactical code was created with black RAF code numbers from an Xtradecal Lightning sheet and another post-war Spitfire (a Special Hobby Mk. 24, IIRC).

The flash on the rudder was created with paint (the blue tone was mixed to match the wing roundels) and a single, white star decal. The squadron emblem, which was not featured on the inspiring profile, was taken from an Xtradecal sheet for D.H. Vampire T.55s, which features two FACh options, one of them operated by Grupo 7. Most stencils come from the Mk 22’s OOB sheet.

 

Some soot stains were added around the exhaust stubs and very little dry-brushing with aluminum and light grey was done to the wings' leading edges, the propeller (spinner tip and blades) and around the cockpit hatch. And, finally, everything was sealed with matt acrylic varnish (Italeri).

 

A simple project, and just an "operator travesty" whif. The kit went together easily, and the result is pretty exotic - but not unbelievalbe, despite the weird choice of colors.

A special thanks needs to be given to Abdullah750Pakistan. This originally started as a project to clean up and make a buildable and more minifig-friendly version of his Ural 63708. As you can see though, it’s turned into a project to create a series of trucks in the same vein of the Oshkosh MTVR, Navistar 7000 MV, and Ural 63704-0010 families.

  

As with my other builds, all parts used in this are real production pieces.

This amazing configuration is found on The Bruce Trail, on The Bruce Peninsula.

This large inland flowerpot or stack was formed by wave action from a post-glacial lake 5,500 years ago. There is a 30 minute hike through the woods, then a few stairs which take you down a bit, then you're on your own, climbing over some fairly precarious rocks to get to this spot. Well worth it though.

Many thanks for your visits and comments.

A bizarre triangular configuration landed in Tolo Harbour tonight. I saw it in the dark and had no idea what it was, so I mounted the camera on a tripod and did a long exposure to see if I can make out what it is, but I cannot.

 

And this is what the “Bulb” mode is for. To do it though you need to use the Canon TC-80N3 timer remote control. Yes, you can do it by hand but if you do bulb by hand then you risk vibrating the capture.

 

Again, you see the lens flair sparkles, yes? These are results of small aperture captures. To do photography well you do need to know how the machines function and how to achieve everything you need. And so you learn by trying new things. Do things manually. Everything is manual here: exposure, ISO, focus (when it is dark like this you can’t rely on anything automatic). And when you do things manually it is always so much more fun!

The fifties meant entry into the jet age for the FACh, and Grupo 7 was the first unit to receive them in 1954. As a consequence, the Chilean Spitfires were soon replaced by Lockheed F-80 fighters, procured from the United States of America, and the last Chilean Spitfire Mk 22s were retired in 1963.

The kit and its assembly:

This build was inspired by a series of South American what-if profiles created by fellow member PantherG at whatifmodelers.com, posted there in February 2019. These included, among others, several Chilean Supermarine Spitfire Mk 22s, including exotic livery variants. I found one of them very attractive (yet ugly...), and when I found an appropriate Special Hobby kit in my stash I decided spontaneously to turn the profile into (model) hardware.

 

The Special Hobby kits for Griffon-powered Spitfires are excellent, and they all actually contain a vast collection of optional parts that allow LOTS of land- and sea-based late Spitfires to be built, including subtle fictional combinations. The parts are crisply molded, the styrene is easy to work with, fit is very good and surface details are just great – the kit almost falls together. The thing is pricy, but you get good value and lots of spares for future projects. In my case it is a proper Mk 22 kit, and this one even came with resin wheels and exhaust stubs as extras, plus a masking set for the canopy.

 

The kit was built almost 100% OOB as a Mk 22, I just modified the propeller with an axis so that it can spin freely (for the pictures). The drop tank comes from the kit, but otherwise I left the aircraft in clean condition, leaving away optional rocket attachment points under the wings or slipper tanks.

  

Painting and markings:

As mentioned above, this build was inspired by a profile drawing, and I stuck as close as possible to this benchmark, even though I changed some details or filled some gaps.

The most striking feature of the specific profile (aircraft “213”) I chose was/is the experimental choice of colors: RAF Mid Stone and Ocean Grey on the upper surfaces, and Azure Blue underneath. I just slightly tweaked the pattern on the model, staying closer to the original RAF scheme and resulting in a slightly different pattern on the fuselage. Consequently, I gave the aircraft a different tactical code and “217” was born.

 

The basic tones I used are Humbrol 106, Modelmaster 2052 and Humbrol 157. The cockpit interior was painted in a post-WWII black (Revell 9) instead of the former pale green-grey. The interior of the landing gear wells became Medium Sea Grey (Humbrol 165); the idea behind this choice is that the late Spitfire types had their landing gear wells painted in the same color as the wings' undersides. In the case of this specific aircraft I thought that it originally carried the standard RAF scheme, but received a superficial overspray in the experimental Chilean colors at the UK workshop. For the same reason, some Dark Green shines through under the Mid Stone on the leading edges and around the cockpit, created through dry-brushing and thinned paint (acrylic Revell 65, Bronze Green). The propeller spinner became black - very simple, and in line with the benchmark profile.

 

The decals were puzzled together. The Chilean roundels on the wings actually belong to an EE/BAC Canberra, the tactical code was created with black RAF code numbers from an Xtradecal Lightning sheet and another post-war Spitfire (a Special Hobby Mk. 24, IIRC).

The flash on the rudder was created with paint (the blue tone was mixed to match the wing roundels) and a single, white star decal. The squadron emblem, which was not featured on the inspiring profile, was taken from an Xtradecal sheet for D.H. Vampire T.55s, which features two FACh options, one of them operated by Grupo 7. Most stencils come from the Mk 22’s OOB sheet.

 

Some soot stains were added around the exhaust stubs and very little dry-brushing with aluminum and light grey was done to the wings' leading edges, the propeller (spinner tip and blades) and around the cockpit hatch. And, finally, everything was sealed with matt acrylic varnish (Italeri).

 

A simple project, and just an "operator travesty" whif. The kit went together easily, and the result is pretty exotic - but not unbelievalbe, despite the weird choice of colors.

The 3-cylinder (fan-configuration) Dual-Over-Head-Cam (DOHC) engine has all cylinders above the center line, but uses a master rod and 2 articulating rods like those used in a radial engine. Each cylinder has two valves (one for intake and one for exhaust) and the camshafts are belt driven 1:2 off of the crankshaft. Two camshafts operate the valves in each cylinder head. One camshaft operates the intake valves and the other the exhaust valves, thus “dual overhead cams.”

+++ DISCLAIMER +++

Nothing you see here is real, even though the conversion or the presented background story might be based historical facts. BEWARE!

 

Some background:

The Supermarine Spitfire is a British single-seat fighter aircraft that was used by the Royal Air Force and many other Allied countries during and after the Second World War. The Spitfire was built in many variants, using several wing configurations, and was produced in greater numbers than any other British aircraft.

 

The Spitfire was designed as a short-range, high-performance interceptor aircraft by R. J. Mitchell, chief designer at Supermarine Aviation Works (which operated as a subsidiary of Vickers-Armstrong from 1928). In accordance with its role as an interceptor, Mitchell designed the Spitfire's distinctive elliptical wing to have the thinnest possible cross-section; this thin wing enabled the Spitfire to have a higher top speed than several contemporary fighters, including the Hawker Hurricane.

 

It was the only British fighter to be in continuous production throughout World War II, and remained in service with several air forces around the world for several years. One of its post-war operators was the Lebanese Air Force, or Al Quwwat al-Jawwiya al-Lubnaniyya (لقوات الجوية اللبنانية‎).

The Lebanese Air Force was established in 1949 under the command of then-Lieutenant Colonel Emile Boustany who later became commander of the army. Soon after its establishment, a number of planes were donated by the British, French, and Italian governments, with additional planes donated by Britain and Italy later that same year.

 

Britain donated 4 Percival Prentices, 2 World War II-era Percival Proctors and seven trpocailized Supermarine Spitfires (six Mk. XVIe and one TR.8 two-seater), while Italy donated 4 Savoia-Marchetti SM.79 bombers which were mainly used for transportation.

 

The Mk XVI Spitfire was a WWII design, and the last variant powered by a Merlin engine and based on the original, sleek fuselage. It was basically the same as the Mk IX, except for the engine, a Merlin 266. The Merlin 266 was the Merlin 66 and was built under licence in the USA by the Packard Motor Company. The "2" was added as a prefix in order to avoid confusion with the engines, as they required different tooling.

 

All Mk XVI aircraft produced (a total of 1,054 Mk XVIs left Castle Bromwich) were of the Low-Altitude Fighter (LF) variety. This was not determined by the length of the wings (clipped wings were fitted to most LF Spitfires), but by the engine, which had been optimised for low-altitude operation. All production Mk XVIs had clipped wings for low altitude work and were fitted with the rear fuselage fuel tanks with a combined capacity of 75 gal. Many XVIs featured cut-down rear fuselages with bubble canopies. On these aircraft the rear fuselage tank capacity was limited to 66 gal.

 

Because of a slightly taller intercooler and rearranged accessories on the Packard Merlins a new, bulged upper cowling was introduced, a detail that also appeared on late production IXs. For the service in the Middel East region the Lebanese machines received dust filters which considerably changed the aircraft's silhouette.

 

Armament consisted of two 20 mm Hispano II cannons - each with 120 rpg - and two 0.50 calibre Browning machine guns - each with 250 rpg. 1 × 500 lb (227 kg) bomb could be carried underneath the centre rack, and 1 × 250 lb (114 kg) bomb could be slung under each wing. As a special feature, the wing hardpoints of the Lebanese Spitfires were "wet" so that slipper tanks with 24 gal. each could be carried, compensating for the reduces rear fuselage tank due to the bubble canopy's lowered dorsal spine.

 

The Lebanese Spitfires only saw a short service, since in 1953, jet fighters were introduced when 16 de Havilland Vampire jets were received, and the first Hawker Hunters arrived in 1959, which replaced the obsolete Spitfires. This initial Hunter batch was followed by more Hunters through 1977.

 

In 1968, 12 Mirage IIIELs were delivered from France but were grounded in the late 1970s due to lack of funds. In 2000, the grounded Mirages were sold to Pakistan, and four Hunters were even revived in 2008 and served until 2014.

The kit and its assembly:

This whif is based on a simple idea: how did Lebanon's Air Force start? Small countries make a good whif playground, and I guess that nobody has the Lebanon on his/her list...?

Another factor was that I had some Austrian roundels left in store that could, with a green dot, easily be turned into Lebanese markings. So the theme was quickly settled, but the details take some preparation time, so the idea lingered for some time.

 

After some legwork I deemed a simple Spitfire with a dust filter worthy as an initial aircraft, and the respective Hobby Boss kit of a Spitfire Mk. VB in the stash came handy.

But somehow this was a bit dull, and at the inception of the Lebanon Air Force there were better option available than an early Mk. V. I still wanted a sleek, Merlin-powered Spitfire variant, though, and eventually settled for the Mk. XVI - with its clipped wings and the bubble canopy it has a very distinctive look.

 

When a "1 Week group Build" at whatifmodelers.com in the Easter Week 2015 was announced, I took this occassion to build the Lebanese Spitfire.

 

By that time I already had a basis kit at hand (Heller's Spitfire XVI) as well as some donation parts and decals.

Work was strightforward, the Heller kit was built almost OOB. It's a rather old model kit, with raised panel lines, but good detail. The material is thin, so the built item lacks some structural stability! On the other side, this makes some minor mods really easy: I lowered the flaps and moved the tail rudders slightly off of neutral position. I also opened the cockpit "door" on the left side for later static display, even though the cockpit itself was left OOB. It's a bit "flat", but for the kit's age it's pretty good, and the injected canopy is crystal clear and fits perfectly.

 

I had some major woes concerning the fit for the forward fuselage, and even more when I tried to mate wings and fuselage: there was a 1mm gap(!) on both sides that had to be bridged with putty, and the thin and flexible material did help much...

 

Other mods concern the propeller (added a styrene tube and a metal axis for free spin), the radiators (these are molded into the lower wings - sounds horrible, but is made very well and thin, I just added some foamed styrene inside as protective mesh because OOB there's just a blank "box" inside) and the kit received a dust filter - a resin piece taken from a Pavla conversion set for Hawker Hurricanes.

  

Painting and markings:

While a donated RAF Spitfire would certainly have carried a desert paint scheme in Dark Earth/Mid Stone/Azure Blue or a late WWII Dark Green/Ocean Grey/Light Sea Grey livery I settled for something more individual and effective for the rugged Levantine terrain.

In this case I went for the rarely used RAF 'Tropical Scheme' in Mid Stone/Dark Green from above and with Mediterrenean Blue undersides.

 

The pattern itself is standard RAF, the upper cammo taken down onto the dust filter's flanks was taken over from RAAF Spitfires during WWII (RAF aircraft would carry a higher waterline, with the filter painted completely in the lower surface's tone). Basic paints are RAF Dark Green from Modelmaster and Humbrol 84 (RAF Mid Stone) - rather authentic. But I used Humbrol 87 (Steel Grey) for the undersides - it's rather intense and has a greenish hue, and by far not as dark as the typical RAF Azure Blue or PRU Blue.

 

Interior surfaces were painted in RAF Cockpit Green (Modelmaster Authentic), while the landing gear and its wells were kept in Aluminum Dope (Humbrol 56).

 

Decals/markings were puzzled together and improvised. The Lebanese roundels are actually Austrian national markings into which a dark green dot has ben added manually... the fin flash and the roman/arabic codes come from an Xtradecal aftermarket sheet.

 

Beyond these basic markings I did not add anything flashy - in 1951 things were rather simple,

The kit received a light shading and some dry painting with light grey, plus a light black ink wash. Soot/exhaust stains were created with grinded graphite and around the engine some leaked oil was added with Tamiya's "Smoke", and everything was sealed under a coat of matt acrylic varnish.

  

I'll admit it's not a spectacular whif, and overall rather simple concerning build and painting. But a proud addition to whatifmodelers.com's "! Week Group Build", even though this was already finished in just three days from sprues to beauty pics...

 

The baseline configuration of the Oshkart SMTV (Scalable Medium Tactical Vehicle) family, the Mk601A is the standard two-door 6x6 cargo hauler configuration.

  

Features include opening doors and top hatch, a cab capable of seating 2 minifigs with body armor and headgear, foldable gunner’s seat, turning front wheels, center-pivoting rear axles, and spare tire with lift arm.

  

A special thanks needs to be given to Abdullah750Pakistan. This originally started as a project to clean up and make a buildable and more minifig-friendly version of his Ural 63708. As you can see though, it’s turned into a project to create a series of trucks in the same vein of the Oshkosh MTVR, Navistar 7000 MV, and Ural 63704-0010 families.

  

As with my other builds, all parts used in this are real production pieces.

The Mikoyan-Gurevich MiG-17 (Russian: Микоян и Гуревич МиГ-17) (NATO reporting name "Fresco") is a Soviet jet fighter aircraft, in service from 1952.

 

The MiG-17 design was generally based on a previously successful Mikoyan and Gurevich fighter, the MiG-15. The major novelty was its introduction of a swept wing with a "compound sweep" configuration: a 45° angle near the fuselage, and a 42° angle for the outboard part of the wings. Other easily visible differences to its predecessor were the three wing-fences on each wing, instead of the MiG-15's two, and the addition of a ventral fin. The MiG-17 shared the same Klimov VK-1 engine and the rest of its construction was similar. The first prototype, designated "SI" by the construction bureau, was flown on the 14 January 1950, piloted by Ivan Ivashchenko.

 

Despite the SI prototype's crash on 17 March 1950, tests of another prototype "SI-2" and experimental series aircraft "SI-02" and "SI-01" in 1951, were generally successful, and on 1 September 1951 the aircraft was accepted for production. It was estimated that with the same engine as the MiG-15's, the MiG-17's maximum speed is higher by 40-50 km/h, and the fighter has greater manoeuvrability at high altitude.

 

Serial production started in August 1951. During production, the aircraft was improved and modified several times. The basic MiG-17 was a general-purpose day fighter, armed with three cannons and considered to be most effective in action against enemy aircraft. It could also act as a fighter-bomber, but its bombload was considered light relative to other aircraft of the time, and it usually carried additional fuel tanks instead of bombs.

 

The second prototype variant, "SP-2", was an interceptor equipped with a radar. Soon a number of MiG-17P all-weather fighters were produced with the Izumrud radar and front air intake modifications. In the spring of 1953 the MiG-17F day fighter entered production. Fitted with the VK-1F engine with an afterburner, which improved its performance, it became the most popular variant of the MiG-17. The next mass-produced variant with afterburner and radar was the MiG-17PF. In 1956 a small series (47 aircraft) was converted to the MiG-17PM standard (also known as PFU) with four first-generation Kaliningrad K-5 (NATO reporting name AA-1 'Alkali') air-to-air missiles. A small series of MiG-17R reconnaissance aircraft were built with VK-1F engine (after first being tested with the VK-5F engine).

 

Several thousand MiG-17s were built in the USSR by 1958.

  

Licence production

 

Lim-5 in Polish Air Force markingsIn 1955, Poland received a license for MiG-17 production. The MiG-17F was produced by the WSK-Mielec factory under the designation Lim-5. The first Lim-5 was built on November 28 1956 and 477 were built by 1960. An unknown number were built as the Lim-5R reconnaissance variant, fitted with the AFA-39 camera. In 1959-1960, 129 MiG-17PF interceptors were produced as the Lim-5P. PZL-WSK also developed several Polish attack plane variants based on the MiG-17: the Lim-5M, produced from 1960; Lim-6bis, produced from 1963; and Lim-6M (converted in the 1970s); as well as two reconnaissance variants: the Lim-6R (Lim-6bisR) and MR.

 

In China, an initial MiG-17F was assembled from parts in 1956, with license production following in 1957 at Shenyang. The Chinese-built version is known as the Shenyang J-5 (for local use) or F-5 (for export — not to be confused with the F-5 Freedom Fighter). According to some sources, earlier MiG-17s which had been delivered directly from the USSR were designated "J-4". From 1964, the Chinese produced a radar-equipped variant similar to the MiG-17PF, which was known as the J-5A (F-5A). The Chinese also developed a two-seat trainer variant, the JJ-5 (FT-5 for export), which integrated the cabin of the JJ-2 (a license-built MiG-15UTI) with the J-5. It was produced in 1966-1986, being the last-produced MiG-17 variant and its only twin-seater variant. The Soviets did not produce a two-seat MiG-17 as they felt that the training variant of the older MiG-15 was sufficient.

  

[edit] Technical description

Day-fighter variants (MiG-17, MiG-17F) were armed with two NR-23 23 mm cannons (80 rounds each) and one N-37 37 mm cannon (40 rounds), which were mounted on a common bed under the central air intake. The gun bed could be easily wound down for maintenance. On radar-equipped variants (MiG-17P, MiG-17PF), the N-37 37 mm cannon was replaced with a third NR-23 23 mm cannon (carrying 100 rounds each) to compensate for the weight aft of the radar. All variants could carry 100 kg bombs on two underwing pylons and some could carry 250 kg bombs; however, these pylons were usually used for 400 l fuel tanks. The MiG-17R was armed with two 23 mm cannons.

 

The only variant with air-to-air missiles was the MiG-17PM (or MiG-17PFU), which could carry four K-5 (NATO: AA-1 'Alkali'). It had no cannons. Some countries occasionally modified their MiG-17s to carry unguided rockets or bombs on additional pylons.

 

The MiG-17P was equipped with the Izumrud-1 (RP-1) radar, while the MiG-17PF was initially fitted with the RP-1 which was later replaced with the Izumrud-5 (RP-5) radar. The MiG-17PM was also equipped with a radar, used to aim its missiles. Other variants had no radar.

  

[edit] Operational history

 

A Soviet-built Egyptian MiG-17The strategic purpose of this, and most other Soviet fighters, was to shoot down US bombers, not engage in dogfights. This subsonic (.93 Mach) fighter was effective against slower (.6-.8 Mach), heavily loaded US fighter-bombers, as well as the mainstay American strategic bombers during the MiG-17's development cycle (such as the B-50 or B-36, which were both still powered by piston engines). Even if the target had sufficient warning and time to shed weight and drag by dropping external ordnance and accelerate to supersonic escape speeds, doing so would have inherently forced the enemy aircraft to abort its bombing mission. By the time the USAF introduced strategic bombers capable of cruising at supersonic speeds such as the B-58 Hustler and FB-111, however, the MiG-17 became obsolete in PVO service and was supplanted by supersonic interceptors such as the MiG-21 and MiG-23.

 

Twenty countries flew MiG-17s. The MiG-17 became a standard fighter in all Warsaw Pact countries in the late 1950s and early 1960s. They were also bought by many other countries, mainly in Africa and Asia, that were neutrally aligned or allied with the USSR.

 

MiG-17s were not available for the Korean War, but saw combat for the first time over the Straits of Taiwan when PRC MiG-17s clashed with ROC F-86 Sabres in 1958. The MiG-17 was the primary interceptor of the fledgling Vietnam People's Air Force in 1965 and scored its first victories and saw considerable action during the Vietnam War, when they frequently worked in conjunction with MiG-21s and MiG-19s. Some Vietnamese pilots, in fact, preferred the MiG-17 over the MiG-21; it was more agile, though not as fast.

 

The American fighter community was shocked in 1965 when elderly, subsonic MiG-17s downed sophisticated Mach-2-class F-105 Thunderchief fighter-bombers over North Vietnam. To redress disappointing combat performance against smaller, more agile fighters like the MiGs, the Americans established dissimilar air combat training (DACT) in training programs such as "TOPGUN", which employed subsonic A-4 Skyhawk aircraft to mimic more manoeuvrable opponents such as the MiG-17. The US Navy also set Adversary squadrons equipped with the nimble A-4 at each of its fighter and attack Master jet bases to provide DACT.

 

MiG-17s also flew against Israel in the various Arab-Israeli conflicts. At least 24 of them served with the Nigerian Air Force and were flown by a mixed group of Nigerian and mercenary pilots from East Germany, Russia, Great Britain and South Africa during the 1967-70 Nigerian Civil War.
