The de Havilland DH.103 Hornet, developed by de Havilland, was a fighter aircraft driven by two piston engines. It further exploited the wooden construction techniques that had been pioneered by the de Havilland Mosquito. Development of the Hornet had started during the Second World War as a private venture. The aircraft was to conduct long range fighter operations in the Pacific Theatre against the Empire of Japan but the war ended before the Hornet reached operational squadron status.
The Ikarus Aero 2 was a piston-engined military trainer aircraft built in Yugoslavia in the years following World War II, although the design pre-dated the war.
The Miles M.77 Sparrowjet was a twin-engined jet-powered racing aircraft built by the British aircraft manufacturer F.G. Miles Limited. It was a one-off conversion, involving the fitting of Turbomeca Palas turbojet engines to the prototype Miles Sparrowhawk, enabling the aircraft to achieve higher performance than could be achieved with its conventional piston engine arrangement.
The McDonnell XP-67 "Bat" or "Moonbat" was a prototype for a twin-engine, long-range, single-seat interceptor aircraft for the United States Army Air Forces. Although the design was conceptually advanced, it was beset by numerous problems and never approached its anticipated level of performance. The project was cancelled after the sole completed prototype was destroyed by an engine fire.
The I.Ae. 30 "Ñancú" was an Argentine twin piston engined fighter designed by the Instituto Aerotécnico in the late 1940s, similar to the de Havilland Hornet, but made of metal rather than wood. Only one prototype was completed; the project was abandoned in favour of the FMA I.Ae. 27 Pulqui I jet aircraft.
The Turbomeca Palas is a diminutive centrifugal flow turbojet engine used to power light aircraft. An enlargement of the Turbomeca Piméné, the Palas was designed in 1950 by the French manufacturer Société Turbomeca, and was also produced under licence by Blackburn and General Aircraft in the United Kingdom and Teledyne Continental Motors in the United States as the Continental Model 320.
The Gotha G.II series was a heavy bomber used by the Luftstreitkräfte during World War I.
The Bellanca 28-92 Trimotor was a racing aircraft built to compete in the Istres-Damascus-Paris Air Race of 1937, and was paid for by popular subscription in Romania. Christened Alba Julia it was piloted by Captain Alexander Papana of the Romanian Air Force.
The Dassault M.D.320 Hirondelle was a French 14-seat utility transport aircraft of the 1960s, designed and built by Dassault Aviation, in prototype form only.
The Miles M.5 Sparrowhawk was a 1930s British single-seat racing and touring monoplane designed by Miles Aircraft Limited.
The Ikarus 452 was an experimental jet aircraft built in Yugoslavia in 1953. It was a stubby mid-wing cantilever monoplane of pod-and-boom configuration, with twin jets mounted one atop the other at the rear of the fuselage nacelle, with separate intakes for the lower engine and the upper engine. The twin tails and horizontal stabiliser were carried at the ends of booms that extended rearwards from the wings, with a short fin extending from the top of the rear fuselage to also meet the stabiliser. The flying surfaces were sharply swept, and construction throughout was of an experimental alloy.
The SNCASE SE.100 was a French two-seat, twin-engined fighter that first flew in 1939. Mass production was planned to begin late in 1940 but the Fall of France prevented this.
The Blohm & Voss P 194 was a German design for a mixed-power Stuka or ground-attack aircraft and tactical bomber, during World War II.
The Fokker D.XXIII was a Dutch single-seat fighter designed and built by Fokker. Only one aircraft was flown before the country was invaded by the Germans in May 1940.
The Ikarus 215 twin-engine plane, was a Yugoslav light bomber and a training aircraft of mixed construction, the prototype flew in 1949. It did not go into production. The prototype was used for training and as a liaison. It was designed and built at the Ikarus factory in Zemun-Belgrade.
The Payen Arbalète was a small, pusher configuration, experimental French tailless aircraft, designed by Nicolas Roland Payen, and first flown in 1965.
The Blohm & Voss P 204 was one of several design studies by Blohm & Voss for asymmetric dive bombers during World War II. It was also unusual in having hybrid propulsion comprising both piston and jet engines.
The Henri Farman HF.35 was a large 3-seat biplane designed and built in France by Henri Farman during 1915.
