The Bréguet Br 960 Vultur was a prototype two-seat carrier-based attack and anti-submarine aircraft (ASW) built for the French Navy during the early 1950s. Meeting contradictory endurance and speed requirements, it was designed as a "mixed-power" aircraft with a turboprop engine in the front and a turbojet in the rear. Only two examples were built, but the second aircraft was rebuilt as the prototype of the Bréguet 1050 Alizé ASW aircraft after the Navy dropped the idea of a turboprop attack aircraft in the mid-1950s.
The XB-59, Boeing model number 701, was a 1950s proposal for a United States supersonic bomber aircraft.
The Boulton Paul P.120 was a research aircraft designed and produced by the British aircraft manufacturer Boulton Paul. It was the last aircraft design by the company to be flown.
The Sukhoi Su-10 or Izdeliye Ye was a Soviet turbojet-powered bomber aircraft built shortly after World War II.
The Fokker V.1 was a small German sesquiplane experimental fighter prototype built in 1916 by the Fokker-Flugzeugwerke. Sporting a parasol wing, it was the first Fokker aircraft purportedly designed by Reinhold Platz—the respective roles played by Fokker himself, Platz, and possibly others in the conceptual design of Fokker airplanes are a matter of dispute among historians—and was an early experiment in cantilever wing construction, eliminating the bracing wires typical of aircraft design at the time, something that had already been achieved with metal materials in Hugo Junkers' own pioneering Junkers J 1 in 1915.
The Bell Model 65 Air Test Vehicle (ATV) was an experimental tiltjet VTOL aircraft built by Bell using parts from a number of general aviation aircraft.
The OKB-1 150 was a jet bomber designed and produced in the Soviet Union from 1948.
The Miles M.15 was a 1930s British single-engined monoplane trainer aircraft with two open cockpits, designed and developed by Miles Aircraft. Like other aircraft constructed to the official specification, it failed to meet the performance requirements, and only two were built.
The Yakovlev Yak-1000 was a Soviet supersonic technology demonstrator intended to evaluate the aerodynamic layout and field performance of the cropped delta wing discussed in captured German documents in combination with the new Lyulka AL-5 turbojet. The tandem undercarriage proved to be unsatisfactory and there were serious flight stability problems related to the delta wing, enough so that it never flew after an accident during taxiing tests.
The Yakovlev Yak-140 was a Soviet prototype lightweight supersonic fighter developed during the 1950s. The prototype was completed in 1954, but it was denied authorization to enter flight testing and the program was cancelled in 1956.
The Slingsby Type 51 Dart is a single seat competition glider designed in the early 1960s, initially as a 15 m span Standard Class aircraft but evolved into an Open Class, 17 m sailplane. It was the last Slingsby sailplane to be mostly constructed of wood.
The SNCASO SO.9000 Trident is a French mixed-power interceptor aircraft built by aircraft manufacturer SNCASO during the 1950s. As part of a wider effort to re-build French military power during the late 1940s and to furnish France with advanced, new domestically produced designs, a request for a supersonic-capable point-defence interceptor aircraft to equip the French Air Force was issued to SNCASO. In response, the firm designed the mixed-propulsion Trident, powered by a single SEPR rocket engine, which was augmented by wingtip-mounted turbojet engines, and the Air Force ordered two prototypes.
The Akaflieg Darmstadt D-34 sailplanes were a series of experimental single seat sailplanes, designed at the University of Darmstadt in the 1950s and early 1960s to explore the structural and aerodynamic advantages of the then emerging plastics and composite materials.
The Antonov A-9 was a single-seat sailplane designed and built in the USSR in the 1940s, a development of the record setting Red Front 7.
The Procaer Cobra was a two-seat turbojet powered light aircraft designed and built in Italy and flown in the early 1960s. Only one was completed.
The CVV-6 Canguro was a high performance two seat glider, designed at Milan Polytechnic University in 1940. A small batch was ordered for the Italian Air Force but few were delivered; more were produced after World War II, becoming the most common Italian gliding club machine. Some were still in use in the 1980s. In 1954 a Canguro came second at the World Gliding Championships at Camphill Great Hucklow, Derbyshire, England. One was modified into a powered aircraft, at first with a piston engine and later with a turbojet.
The Sud-Ouest SO.6020 Espadon (Swordfish) was a French post-war prototype interceptor designed and built by SNCASO during the late 1940s. The French Air Force judged the design a failure despite some records being set and cancelled plans to put it into service in 1951. Only four aircraft were built and they were later modified to serve as testbeds for the mixed rocket and turbojet-powered SNCASO SO.9000 Trident program. Only one badly damaged aircraft survives.
The 1923 Feiro I was the first Hungarian designed and built civil transport aircraft, modified in 1925 by an engine change into the Feiru Daru (Crane). Neither was a commercial success.
The WNF Wn 16 was an Austrian experimental aircraft built near the start of World War II to test the properties of the then-new tricycle undercarriage arrangement.
The Mauboussin M.112, M-12 or Mauboussin M.XII was originally called the Peyret-Mauboussin PM XII and was renamed when Mauboussin founded his own company in 1931, ending his partnership with Louis Peyret. It was a French, single-engine, two-seat, low cantilever wing touring monoplane. At least six were built.
