PB-2
The Consolidated P-30 (PB-2) was a 1930s United States two-seat fighter aircraft. An attack version called the A-11 was also built, along with 2 Y1P-25 prototypes and YP-27, Y1P-28, and XP-33 proposals. The P-30 is significant for being the first fighter in United States Army Air Corps service to have retractable landing gear, an enclosed and heated cockpit for the pilot, and an exhaust-driven turbo-supercharger for altitude operation. Design and development In 1931, the Detroit Aircraft Corporation, parent company of the Lockheed Aircraft Company, built a two-seat single-engined fighter aircraft based on the Lockheed Altair high-speed transport as a private venture. The prototype, the Detroit-Lockheed XP-900, flew in September 1931 and was purchased by the United States Army Air Corps as the Lockheed YP-24. It had impressive performance, being faster than any fighter then in service with the Air Corps, and an order for five Y1P-24 fighters and four Y1A-9 attack aircraft was plac ...

94th Pursuit Squadron
The 94th Fighter Squadron is a unit of the United States Air Force 1st Operations Group located at Joint Base Langley–Eustis, Virginia. The 94th is equipped with the F-22 Raptor. The 94 FS is one of the oldest units in the United States Air Force, first being organized on 20 August 1917 as the 94th Aero Squadron of the United States Army Air Service at Kelly Field, Texas. The squadron deployed to France and fought on the Western Front during World War I as a pursuit squadron. It took part in the Champagne-Marne defensive; Aisne-Marne offensive; St. Mihiel offensive, and Meuse-Argonne offensive.Gorrell, History of the 94th Aero Squadron In 1924, it was consolidated with the 103d Aero Squadron (Pursuit). The 103d was largely composed of former members of the French Air Service Lafayette Escadrille (from the French ''Escadrille de Lafayette''). This was a squadron of American volunteer pilots who had joined the French Air Service prior to the United States entry into ...

Seversky P-35
The Seversky P-35 is an American fighter aircraft built by the Republic Aviation, Seversky Aircraft Company in the late 1930s. A contemporary of the Hawker Hurricane and Messerschmitt Bf 109, the P-35 was the first single-seat fighter in United States Army Air Corps to feature Aluminum, all-metal construction, Landing gear, retractable landing gear, and an enclosed cockpit. Design and development The origins of the P-35 can be traced back to the Seversky SEV-3 three-seat amphibian aircraft, amphibian, designed by Alexander Kartveli, Seversky's chief designer and Seversky's first aircraft. The SEV-3 first flew in June 1933 and was developed into the Seversky BT-8 basic trainer, 30 of which were ordered by the United States Army Air Corps (USAAC) in 1935.Green and Swanborough 1979, pp. 8–9. This proved grossly underpowered and was quickly replaced by the North American BT-9.Davies 1994, p. 4. The second prototype SEV-3 was completed as a two-seat fighter derivative, the SEV-2XP. ...

Radial Engine
The radial engine is a reciprocating engine, reciprocating type internal combustion engine, internal combustion engine configuration in which the cylinder (engine), cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized Star polygon, star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings ar ...

Curtiss V-1570-27
The Curtiss V-1570 Conqueror was a V12 liquid-cooled aircraft engine. Representing a more powerful version of the Curtiss D-12, the engine entered production in 1926 and flew in numerous aircraft.Gunston 1989, p. 46. Design and development Designed in 1924 as a military successor to the Curtiss D-12, initially named the Conqueror, it was later given the military designation of V-1570 based on its displacement of 1,570 cubic inches (26 L). The engine featured open-ended cylinder liners (advanced technology for the period) and pressurized liquid cooling. Developments including the use of a supercharger gradually increased power output until reliability problems due to overheating and coolant leaks became apparent. Military funding for further development of the Conqueror was cut in 1932, efforts by Curtiss to market the engine for civil airliners failed and the line was dropped from production.

Curtiss P-36 Hawk
The Curtiss P-36 Hawk, also known as the Curtiss Hawk Model 75, is an American-designed and built fighter aircraft of the 1930s and 40s. A contemporary of the Hawker Hurricane and Messerschmitt Bf 109, it was one of the first of a new generation of combat aircraft—a sleek monoplane design with a retractable undercarriage making extensive use of metal in its construction. Perhaps best known as the predecessor of the Curtiss P-40 Warhawk, the P-36 saw little combat with the United States Army Air Forces during World War II. It was the fighter used most extensively and successfully by the French Air Force during the Battle of France. The P-36 was also ordered by the governments of the Netherlands and Norway but did not arrive in time to see action before both were occupied by Nazi Germany. The type was also manufactured under license in China, for the Development of Chinese Nationalist air force (1937–1945), Republic of China Air Force, as well as in British India, for the Royal ...

Allison V-1710
The Allison V-1710 aircraft engine designed and produced by the Allison Engine Company was the most common United States, US-developed V12 engine, V-12 Internal combustion engine cooling, liquid-cooled engine in service during World War II. Versions with a turbocharger gave excellent performance at high altitude in the twin-engined Lockheed P-38 Lightning, and turbo-superchargers were fitted to experimental single-engined fighters with similar results. The United States Army Air Corps (USAAC) preference for turbochargers early in the V-1710's development program meant that less effort was spent on developing suitable mechanically driven centrifugal superchargers for the Allison V-12 design, as other V-12 designs from friendly nations like the British Rolls-Royce Merlin were already using. When smaller-dimensioned or lower-cost versions of the V-1710 were desired, they generally had poor performance at higher altitudes. Design and development The Allison Engine Company, Allis ...

Boeing P-26 Peashooter
The Boeing P-26 "Peashooter" is the first American production all-metal fighter aircraft and the first pursuit monoplane to enter squadron service with the United States Army Air Corps. Designed and built by Boeing, the prototype first flew in 1932, and the type was still in use with the U.S. Army Air Corps as late as 1941 in the Philippines. There are two surviving Peashooters and three reproductions on display, with two more under construction. Design and development The project, funded by Boeing, to produce the Boeing Model 248 began in September 1931, with the US Army Air Corps supplying the engines and the instruments. The open cockpit, fixed landing gear, externally braced wing design was the last such design procured by the USAAC as a fighter. The Model 248 had a high landing speed, which caused a number of accidents. To remedy this, Flap (aircraft), flaps were fitted to reduce the landing speed. The Army Air Corps ordered three prototypes, designated ''XP-936'', which fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Race
Air racing is a type of motorsport that involves airplanes or other types of aircraft that compete over a fixed course, with the winner either returning the shortest time, the one to complete it with the most points, or to come closest to a previously estimated time. History The first 'heavier-than-air' air race was held on 23 May 1909 in aviation, 1909 - the Prix de Lagatinerie, at the Port-Aviation aerodrome (often called "Juvisy Airfield") in Viry-Châtillon south of Paris, France. Four pilots entered the race, two started, but nobody completed the full race distance; though this was not unexpected, as the rules specified that whoever travelled furthest would be the winner if no-one completed the race. Léon Delagrange, who covered slightly more than half of the ten laps was declared the winner. Some other minor events were held before the ''Grande Semaine d'Aviation de la Champagne'' in 22–29 August 1909 at Reims, France, Reims, France. This was the first major intern ...
