Bell XP-52
The Bell XP-52 and subsequent XP-59 were World War II fighter aircraft design projects by the American Bell Aircraft Corporation. Both projects featured a twin-boom layout with a rear-mounted engine driving pusher contra-rotating propellers. When the XP-59 project was canceled the designation XP-59A was used as a cover for a secret jet fighter prototype, which would enter production as the P-59 Airacomet. XP-52 The XP-52 design was begun by the Bell Company in 1940, separate from the R-40C competition, under the Air Material Command designator MX-3. The short fuselage carried a piston engine in the rear, driving a pair of contra-rotating propellers in a pusher configuration. The wings were swept back at an angle of 20 degrees, with a horizontal stabilizer mounted behind the propeller on twin booms running back from the wings. The fuselage was unusually streamlined, being round and barrel-shaped, with the forward-located pilot's cockpit fully faired-in to its lines and the ...

Twin-boom Aircraft
A twin-boom aircraft is characterised by two longitudinal booms (extended nacelle-like bodies). The booms may contain ancillary items such as fuel tanks and/or provide a supporting structure for other items. Typically, twin tailbooms support the tail surfaces, although on some types such as the Rutan Model 72 Grizzly the booms run forward of the wing. The twin-boom configuration is distinct from twin-fuselage designs in that it retains a central fuselage. Design The twin-boom configuration is distinct from the twin fuselage type in having a separate, short fuselage housing the pilot and payload. It has been adopted to resolve various design problems with the conventional empennage for aircraft in different roles. Engine mounting For a single engine with a propeller in the pusher configuration or a jet engine, a conventional tail requires the propeller or exhaust to be moved far aft, requiring either a very long driveshaft or jet pipe and thus reducing propulsive efficien ...

Bell Aircraft
The Bell Aircraft Corporation was an American aircraft manufacturer, a builder of several types of fighter aircraft for World War II but most famous for the Bell X-1, the first supersonic aircraft, and for the development and production of many important civilian and military helicopters. Bell also developed the Reaction Control System for the Mercury Spacecraft, North American X-15, and Bell Rocket Belt. The company was purchased in 1960 by Textron, and lives on as Bell Textron. History As a pilot, Larry Bell saw his first plane at an air show, starting a lifelong fascination with aviation. Bell dropped out of high school in 1912 to join his brother in the burgeoning aircraft industry at the Glenn L. Martin Company, where by 1914 he had become shop superintendent. By 1920, Bell was vice president and general manager of Martin, then based in Cleveland. Feeling that he deserved part ownership, in late 1924, he presented Martin with an ultimatum. Mr. Martin refused, and Bell q ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

SNCASO SO
SNCASO (abbreviated from ''Société nationale des constructions aéronautiques du Sud-Ouest'', or commonly, ''Sud-Ouest'') was a French aircraft manufacturer. Created during 1936 as one of seven nationalised aeronautical manufacturing companies, SNCASO became a key French aircraft manufacturer following the end of the Second World War. It produced numerous innovation aircraft; amongst the company's more notable projects was the first French jet aircraft, the Sud-Ouest Triton, and the first indigenously-developed French helicopter, the Sud-Ouest Djinn. On 1 March 1957, SNCASO merged with another French nationalised aviation company, SNCASE, (''Société nationale des constructions aéronautiques du Sud-Est''), to form Sud Aviation. History Following the resolution of the 1936 general strike of French heavy industry, the government of Léon Blum introduced an act to nationalize the French war industry. The act provided for the creation of seven nationalised aeronautical manufa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vultee XP-54
The Vultee XP-54 ''Swoose Goose'' was a prototype fighter built by the Vultee Aircraft Company for the United States Army Air Forces (USAAF). Design and development Vultee submitted a proposal in response to a U.S. Army Air Corps request for an unusual configuration. The Vultee design won the competition, beating the Curtiss XP-55 Ascender and the Northrop XP-56 Black Bullet. Vultee designated it Model 84, a descendant of their earlier Model 78. After completing preliminary engineering and wind tunnel tests, a contract for a prototype was awarded on 8 January 1941. A second prototype was ordered on 17 March 1942. Although it appeared to be a radical design, performance was lackluster, and the project was canceled. The XP-54 was designed with a pusher engine in the aft part of the fuselage. The tail was mounted rearward between two mid-wing booms, with the twelve-foot propeller between them. The design included a "ducted wing section" developed by the NACA to potentially enab ...

De Havilland Vampire
The de Havilland Vampire is a British jet fighter which was developed and manufactured by the de Havilland, de Havilland Aircraft Company. It was the second jet fighter to be operated by the Royal Air Force, RAF, after the Gloster Meteor, and the first to be powered by a single jet propulsion, jet engine. Development of the Vampire as an experimental aircraft began in 1941 during the Second World War, to exploit the revolutionary innovation of jet propulsion. From the company's design studies, it was decided to use a single-engine, twin-boom aircraft, powered by the de Havilland Goblin, Halford H.1 turbojet (later produced as the Goblin). Aside from its propulsion system and twin-boom configuration, it was a relatively conventional aircraft. In May 1944 it was decided to produce the aircraft as an interceptor aircraft, interceptor for the Royal Air Force (RAF). In 1946 the Vampire entered operational service with the RAF, only months after the war had ended. The Vampire quick ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bell P-63 Kingcobra
The Bell P-63 Kingcobra is an American fighter aircraft that was developed by Bell Aircraft during World War II. Based on the preceding Bell P-39 Airacobra, the P-63's design incorporated suggestions from P-39 pilots and was superior to its predecessor in virtually all respects. The P-63 was not accepted for combat use by the United States Army Air Forces. However, it was used during World War II by the Soviet Air Force,Angelucci and Matricardi 1978, p. 100. which had also been the most prolific user of the P-39. Design and development XP-39E While the P-39 had been introduced as an interceptor, later in its development it was decided to reduce the cost and complexity of the engine by removing the turbocharger. High-altitude performance suffered dramatically as a result, and Bell proposed an experimental series to test out a variety of solutions. The resulting XP-39E featured two primary changes from the earlier P-39D from which it was developed. One was a redesigned wing. Th ...

Continental XI-1430
The Continental XI-1430 ''Hyper engine'' (often identified as the IV-1430) was a liquid-cooled aircraft engine developed in the United States by a partnership between the US Army Air Corps and Continental Motors. It was the "official" result of the USAAC's hyper engine efforts that started in 1932, but never entered widespread production as it was not better than other available engines when it finally matured. In 1939, the I-1430-3 was designated as the engine to power the Curtiss XP-55, an extremely radical (for the time) pusher-engine fighter design that would not reach production.Balzer p 28 Development In the late 1920s Harry Ricardo wrote a paper on the sleeve valve design that led to the USAAC's hyper engine efforts. He claimed that the 1 hp/in³ goal was impossible to achieve with poppet valve type engines. The USAAC engineering team at Wright Field decided to test this claim by beating it. The I-1430 was the result of an experimental effort at Wright Field to bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
