Martin PS-30
The Martin 156, referred to in the press variously as the "Russian Clipper", "Moscow Clipper", or "Soviet Clipper" was a very large flying boat aircraft intended for trans-Pacific service. The single example of the M-156 was designed and built in response to a request from Pan American World Airways to provide a longer-range replacement for the Martin M-130. Design and development Glenn L. Martin Company, Martin delivered three Martin Ocean Transport Model-130s (M-130) to Pan Am in 1935 which were flown as the ''China Clipper'', ''Pan Am Flight 1104, Philippine Clipper'' and ''Hawaii Clipper''. Pan Am rejected the M-156 in preference to the Boeing 314 for its replacement. Pan Am was seeking to expand its trans-Pacific air service between San Francisco and Hong Kong in 1937 in aviation, 1937. This route had been pioneered by the Martin M-130 and Pan Am was in need of a larger aircraft. The San Francisco to Hawaii flight was and took 18 – 20 hours. Pan Am would have configur ...

Latécoère 631
The Latécoère 631 was a civil transatlantic flying boat built by Latécoère, the largest ever built up to its time. The type was not a success, being unreliable and uneconomic to operate. Five of the eleven aircraft built were written off in accidents and one was lost during World War II. Design and development The Latécoère 631 was the result of a specification issued in 1936 by the Direction Générale de l'Aviation Civile for a 40-passenger airliner with a range of . The aircraft was ordered in 1938. It was intended that it would be powered by six Gnome et Rhône P.18 engines of each. A competitor for this specification was the SNCASE SE.200 Amphitrite. Construction of the aircraft was stopped due to the outbreak of World War II and was not resumed until after the signing of the Franco-German Armistice. The prototype, registered F-BAHG, first flew on 4 November 1942. It was subsequently confiscated by the Germans, and passed to the Luftwaffe, who allocated the co ...

Latécoère 521
The Latécoère 521 was a French six-engined double deck flying boat designed and manufactured by Pierre-Georges Latécoère. At the time of its completion, it held the distinction of being the largest aircraft to be built in France as well as one of the first large passenger aircraft capable of flying trans-Atlantic routes. First flown on 10 January 1935, the Laté 521 achieved several world records relating to payload and endurance. It was introduced to passenger service by national operator Air France, who was able to launch several previously-unattainable long distance passenger routes. As a civilian aircraft, the Laté 521 was outfitted as a luxurious airliner, providing a high level of comfort for up to 72 passengers. Shortly after the outbreak of the Second World War, the Laté 521 were taken over by the French Navy, who typically operated the type as a long distance maritime patrol aircraft. None survived the conflict due to sabotage by the retreating German forces. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kawanishi H6K
The Kawanishi H6K was an Imperial Japanese Navy flying boat produced by the Kawanishi Aircraft Company and used during World War II for maritime patrol duties. The Allied reporting name for the type was Mavis; the Navy designation was . Design and development The aircraft was designed in response to a Navy requirement of 1934 for a long-range flying boat and incorporated knowledge gleaned by a Kawanishi team that visited the Short Brothers factory in the UK, at that time one of the world's leading producers of flying boats, and from building the Kawanishi H3K, a license-built, enlarged version of the Short Rangoon. The "Type S", as Kawanishi called it, was a large, four-engined monoplane with twin tails, and a hull suspended beneath the parasol wing by a network of struts. Three prototypes were constructed, each one making gradual refinements to the machine's handling both in the water and in the air, and finally fitting more powerful engines. The first of these flew on 14 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dornier Do X
The Dornier Do X was the largest, heaviest, and most powerful flying boat in the world when it was produced by the Dornier company of Germany in 1929. First conceived by Claude Dornier in 1924, planning started in late 1925 and after over 240,000 work-hours it was completed in June 1929. Dornier Museum, 45 seconds During the years between the two World Wars, only the Soviet Tupolev ANT-20 ''Maksim Gorki'' landplane of a few years later was physically larger, but at 53 metric tonnes maximum takeoff weight it was not as heavy as the Do X's 56 tonnes. The Do X was financed by the German Transport Ministry and in order to circumvent conditions of the Treaty of Versailles, which forbade any aircraft exceeding set speed and range limits to be built by Germany after World War I, a specially designed plant was built at Altenrhein, on the Swiss side of Lake Constance. The type was popular with the public, but a lack of commercial interest and a number of non-fatal accidents preven ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boeing 314 Clipper
The Boeing 314 Clipper was an American long-range flying boat produced by Boeing from 1938 to 1941. One of the largest aircraft of its time, it had the range to cross the Atlantic and Pacific oceans. For its wing, Boeing re-used the design from the earlier XB-15 bomber prototype. Twelve Clippers were built, nine of which served with Pan Am. Design and development Pan American had requested a truly trans-Pacific flying boat with unprecedented range and double the passenger payload of the airline's Martin M-130. Boeing's bid was successful and on July 21, 1936, Pan American signed a contract for six. Boeing engineers adapted the cancelled XB-15's wing, and replaced the Pratt & Whitney Twin Wasp radial engines with the Wright Twin Cyclone. Pan Am ordered six more aircraft with increased engine power and capacity for 77 daytime passengers as the Boeing 314A. The huge flying boat was assembled at Boeing's Plant 1 on the Duwamish River in Seattle, and towed to Ellio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wright R-1820 Cyclone
The Wright R-1820 Cyclone 9 is an American radial engine developed by Curtiss-Wright, widely used on aircraft in the 1930s through 1950s. It was produced under license in France as the Hispano-Suiza 9V or Hispano-Wright 9V, and in the Soviet Union as the Shvetsov M-25. Design and development The R-1820 Cyclone 9 represented a further development of the Wright P-2 engine dating back to 1925. Featuring a greater displacement and a host of improvements, the R-1820 entered production in 1931. The engine remained in production well into the 1950s. The R-1820 was built under license by Lycoming, Pratt & Whitney Canada, and also, during World War II, by the Studebaker Corporation. The Soviet Union had purchased a license for the design, and the Shvetsov '' OKB'' was formed to metricate the American specification powerplant for Soviet government-factory production as the '' M-25'', with the R-1820's general design features used by the Shvetsov design bureau for many of their future ...

Wright Cyclone Series
Wright Cyclone was the name given to a family of air-cooled radial piston engines designed by the Wright Aeronautical Corporation and used in numerous American aircraft in the 1930s and 1940s. Background The Wright Aeronautical Corporation was formed in 1919, initially to develop liquid-cooled Hispano-Suiza V8 engines under license. The Corporation's first original design, the R1, was also the first successful high-powered radial in the USA. Funded by contracts from the US Navy for new air-cooled radials, Wright started a new design (initially called the P2) in 1924. The resignation of Frederick Rentschler to form the Pratt & Whitney Aircraft Company, along with several key engineering personnel, seriously affected the development of the P2 and it did not go into production. Cyclone family R-1300 Cyclone 7 R-1750 Cyclone 9 A new design was launched in 1926, known as the R-1750 Cyclone. This was a nine-cylinder radial with a displacement of 1750 cu in and internally coole ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flap (aircraft)
A flap is a high-lift device used to reduce the stalling speed of an aircraft wing at a given weight. Flaps are usually mounted on the wing trailing edges of a fixed-wing aircraft. Flaps are used to reduce the take-off distance and the landing distance. Flaps also cause an increase in drag so they are retracted when not needed. The flaps installed on most aircraft are partial-span flaps; spanwise from near the wing root to the inboard end of the ailerons. When partial-span flaps are extended they alter the spanwise lift distribution on the wing by causing the inboard half of the wing to supply an increased proportion of the lift, and the outboard half to supply a reduced proportion of the lift. Reducing the proportion of the lift supplied by the outboard half of the wing is accompanied by a reduction in the angle of attack on the outboard half. This is beneficial because it increases the margin above the stall of the outboard half, maintaining aileron effectiveness and reduc ...
