The Mikoyan-Gurevich MiG-9 was the first turbojet fighter developed by Mikoyan-Gurevich in the years immediately after World War II. It used reverse-engineered German BMW 003 engines. Categorized as a first-generation jet fighter, it was moderately successful, but suffered from persistent problems with engine flameouts when firing its guns at high altitudes due to gun gas ingestion. A number of different armament configurations were tested, but nothing solved the problem. Several different engines were evaluated, but none were flown as the prototype of the Mikoyan-Gurevich MiG-15 promised superior performance.
The Fairchild PT-19 is an American Fairchild Aircraft monoplane primary trainer aircraft that served with the United States Army Air Forces, RAF and RCAF during World War II. It was a contemporary of the Kaydet biplane trainer and was used by the USAAF during Primary Flying Training. As with other USAAF trainers of the period, the PT-19 had multiple designation(s) based on the powerplant installed.
The Douglas Y1B-7 was a 1930s American bomber aircraft. It was the first US monoplane given the B- 'bomber' designation. The monoplane was more practical and less expensive than the biplane, and the United States Army Air Corps chose to experiment with monoplanes for this reason. At the time the XB-7 was ordered, it was being tested by Douglas Aircraft as an observational plane.
The PA-25 Pawnee was an agricultural aircraft produced by Piper Aircraft between 1959 and 1981. It remains a widely used aircraft in agricultural spraying and is also used as a tow plane, or tug, for launching gliders or for towing banners. In 1988 the design rights and support responsibility were sold to Latino Americana de Aviación of Argentina.
The Grumman JF "Duck" was an American single-engine amphibious biplane built by Grumman for the United States Navy during the 1930s. The J2F Duck was an improved version of the JF, with its main difference being a longer float.
The Grumman F3F was the last American biplane fighter aircraft delivered to the United States Navy, and served between the wars. Designed as an improvement on the single-seat F2F, it entered service in 1936. It was retired from front line squadrons at the end of 1941 before it could serve in World War II, and was first replaced by the Brewster F2A Buffalo. The F3F which inherited the Leroy Grumman-designed retractable main landing gear configuration first used on the Grumman FF served as the basis for a biplane design ultimately developed into the much more successful F4F Wildcat.
The Grumman G-164 Ag Cat is a single-engine biplane agricultural aircraft, developed by Grumman in the 1950s.
The Polikarpov I-153 Chaika was a late 1930s Soviet biplane fighter. Developed as an advanced version of the I-15 with a retractable undercarriage, the I-153 fought in the Soviet-Japanese combats in Mongolia and was one of the Soviets' major fighter types in the early years of the Second World War. Three I-153s are still flying.
The Short Sturgeon was a planned British carrier-borne reconnaissance bomber whose development began during Second World War with the S.6/43 requirement for a high-performance torpedo bomber, which was later refined into the S.11/43 requirement which was won by the Sturgeon. With the end of the war in the Pacific production of the aircraft carriers from which the Sturgeon was intended to operate was suspended and the original reconnaissance bomber specification was cancelled.
The Gregor FDB-1 was a Canadian biplane fighter, designed in 1938 by Michael Gregor and manufactured by Canadian Car and Foundry. Despite having some advanced design features such as flush rivetted all-metal construction and a retractable undercarriage, the final generation of biplane fighters was being supplanted by monoplanes and the Gregor FDB-1 was obsolete before it flew. Despite the Royal Canadian Air Force's desperation for modern fighters, the sole example remained unsold and was eventually lost in a fire in 1945. The Gregor FDB-1's model designation stood for Fighter Dive Bomber indicating its intended roles.
The Ilyushin Il-20 was a Soviet prototype for a heavily armored ground-attack aircraft to replace the Ilyushin Il-10. It featured a number of innovative concepts including a cockpit mounted on top of the engine, directly behind the propeller, and wing-mounted autocannon that could be adjusted on the ground to fire level or depressed 23° to allow the aircraft to strafe ground targets while remaining in level flight. However it was slower than the Il-10, and its M-47 engine was problematic in flight tests in 1948–49. It was not placed into production. The test pilots called the aircraft the Gorbach (Hunchback).
The Lockheed XF-104 Starfighter was a single-engine, high-performance, supersonic interceptor prototype for a United States Air Force (USAF) series of lightweight and simple fighters. Only two aircraft were built; one aircraft was used primarily for aerodynamic research and the other served as an armament testbed, both aircraft being destroyed in accidents during testing. The XF-104s were forerunners of over 2,500 production Lockheed F-104 Starfighters.
The Grumman XSBF, also known by the company designation G-14, was an American biplane scout bomber developed by Grumman Aircraft for the United States Navy during the 1930s. Derived from Grumman's successful "Fifi" fighter, the aircraft was developed at a time when the biplane was giving way to the monoplane. In competition against other aircraft it proved to possess inferior performance in its intended role, and did not enter production. The sole prototype went on to serve as a liaison aircraft, as well as being used in experiments by NACA, before being destroyed in a crash in 1939.
The Great Lakes XSG was an amphibious observation aircraft developed in the United States in the early 1930s for a US Navy competition. It was an ungainly and unorthodox biplane design with a single large pontoon mounted below the lower wing. This pontoon extended rearwards and carried the conventional empennage. On top of the lower wing, where the fuselage would normally be located, was a stubby nacelle containing the tractor-mounted engine and the pilot's cockpit. The rear of this nacelle was semi-enclosed with glazing and incorporated a position for a tail gunner. The main units of the wheeled undercarriage retracted into the sides of the central pontoon.
The Piasecki H-16 Transporter was a tandem-rotor transport or rescue helicopter designed by Frank Piasecki and built by Piasecki Helicopter. The prototypes were evaluated by the United States Air Force and Army, but the crash of the second test aircraft led to cancelling the project.
The Westland F.7/30 was a British fighter prototype. A single prototype was built in 1934, but the type was not put in production because its performance fell far below the RAF's requirements. The Gloster Gladiator won the F.7/30 competition.
The Baumann Brigadier was a prototype American light transport aircraft of the late 1940s. It was a twin-engined monoplane, which, unusually, was of pusher configuration. Only two were built, plans for production never coming to fruition.
The Short S.36 was a British two-seat tractor biplane, built by Short Brothers for Francis McClean in 1911. It was later developed into the Short S.41 and Short S.45, which were the first of a long series of similar aircraft built for the RNAS and RFC.
The Pemberton-Billing P.B.1, sometimes known as the "Supermarine", was a 1910s British single-seat flying-boat built by Pemberton-Billing Limited, which later became the Supermarine Aviation Works. Only one P.B.1 was built, and it never flew any distance further than a hop.
The Aerostar AG-6 was a prototype Romanian agricultural aircraft of the late 1980s, developed for IAv, of Bacău. The company was later known as Aerostar.
