The Bartini T-117, was a twin-engined cargo aircraft designed by Robert Ludvigovich Bartini in the USSR from 1944-1948.
From 1944 to 1948 Bartini devoted much effort to the development of the T-117 heavy transport aircraft. Work on the project started whilst Bartini was working at TsKB 29 NKVD as a detainee. Initially designated P-7, the aircraft, designed in both passenger and cargo versions, was a high-wing monoplane with triple vertical tails powered by two Shvetsov ASh-73 18-cylinder radial engines, with take-off rating of 1,700 kW (2,300 hp).
A peculiarity of the project was the fuselage of elliptical cross-section with the larger axis horizontal. The basic assault transport version was designed to carry a load of 8,000 kg (18,000 lb), carrying self-propelled guns, lorries, motorcycles, mortars, artillery pieces of up to 122 mm (4.80 in) calibre and other items loaded through a rear cargo hatch with detachable loading ramps. Because of the wide fuselage, it was possible to transport two GAZ-67 jeeps side by side. Alternatively, 80 troops could be carried on 4 lengthwise rows of seats. There were several passenger versions with different cabin layouts, allowing the carriage of up to 50 passengers over a distance of 1,600 km (990 mi) at a cruising speed of 365 km/h (197 kn; 227 mph).
Construction of a prototype started in 1946, but in 1948 work was halted due to a shortage of ASh-7 engines which were needed for the Tupolev Tu-4 strategic bomber, which had been given priority on the personal directive of Joseph Stalin. There were several projected variants of the T-117 with alternative powerplants, including the Shvetsov ASh-82FN, the experimental Shvetsov ASh-2 four-row radial and the 3,600 kW (4,800 hp) Klimov VK-2 turboprop, but this did not save the project. The uncompleted T-117 prototype never had engines fitted and was scrapped.

General characteristics
Performance
The Tupolev Tu-80 was a Soviet prototype for a longer-ranged version of the Tupolev Tu-4 bomber, an unlicensed, reverse engineered copy of the Boeing B-29 Superfortress. It was cancelled in 1949 in favor of the Tupolev Tu-85 program which offered even more range. The sole prototype was used in various test programs before finally being used as a target.
The Tupolev Tu-75 was a military transport variant of the Tu-4 bomber, an unlicensed, reverse engineered copy of the Boeing B-29 Superfortress. The Tu-75 was similar to the Tu-70 airliner, both using a new, purpose-designed fuselage. The first Soviet military machine of this class, it was equipped with a rear fuselage loading ramp. It was not placed into production because the VVS decided it would be cheaper to modify its existing Tu-4s for the transport mission and to use its existing Lisunov Li-2 and Ilyushin Il-12 transports.
The Tupolev Tu-70 was a Soviet passenger variant of the Tu-4 bomber, an unlicensed, reverse engineered copy of the Boeing B-29 Superfortress. Designed immediately after the end of World War II, it used a number of components from Boeing B-29s that had made emergency landings in the Soviet Union after bombing Japan. It had the first pressurized fuselage in the Soviet Union and first flew on 27 November 1946. The aircraft was successfully tested, recommended for serial production, but ultimately not produced because of more pressing military orders and because Aeroflot had no requirement for such an aircraft. A military cargo aircraft version was the Tupolev Tu-75.
The Mikoyan-Gurevich MiG-8 Utka was a Soviet experimental aircraft. Built of wood, the aircraft was designed and built in 1945 to test the novel canard configuration. It also used a tricycle undercarriage, the first used by the OKB. It was modified to test a variety of vertical stabilizer and wingtip configurations and was later used as a liaison aircraft for many years by the design bureau.
The Yakovlev Yak-11 is a trainer aircraft used by the Soviet Air Force and other Soviet-influenced air forces from 1947 until 1962.
The Antonov An-8 is a Soviet-designed twin-turboprop, high-wing light military transport aircraft.
The Yakovlev Yak-24 is a Soviet twin-engine, tandem rotor, transport helicopter developed by Yakovlev in the 1950s. The Yak-24 saw limited use in the Soviet Air Force, and the exact number produced and duration of service are unknown due to inconsistencies in data.
The Yakovlev Yak-16 was a Soviet light transport that first flew in 1947. Prototypes were built in both passenger and military cargo versions, but neither was put into production as the Antonov An-2 was felt to be more versatile.
The Beriev Be-6 was a flying boat produced by the Soviet Beriev OKB. It was capable of accomplishing a wide variety of missions, such as long-range maritime reconnaissance, coastal and supply line patrols, torpedo/bombing strikes, mine-laying, and transport operations.
The Lisunov Li-2, originally designated PS-84, was a license-built Soviet-version of the Douglas DC-3. It was produced by Factory #84 in Moscow-Khimki and, after evacuation in 1941, at TAPO in Tashkent. The project was directed by aeronautical engineer Boris Pavlovich Lisunov.
The Yakovlev Yak-6 was a Soviet twin-engined utility aircraft, developed and built during World War II. It was used as a short-range light night bomber and a light transport.
The Yakovlev EG (Eksperimentalnyi Gelikopter), also commonly known as the Yak-M11FR-1 and Sh (Shootka), was an experimental aircraft with coaxial rotors. The prototype was first flown by V.V. Tezavrovsky in December 1947.
The Yakovlev Yak-58 is a small, multi-role utility transport and business aircraft. The aircraft features a pusher engine and twin boom tail. It saw limited production in the late 1990s.
The Ilyushin Il-18 was a Soviet four-engined airliner designed and built by Ilyushin immediately after World War II. Although the aircraft itself was successful, its Shvetsov ASh-73TK engines were too unreliable for civilian use and were further needed to equip the Tupolev Tu-4 bomber, so it was cancelled in 1948.
The Polikarpov NB was a Soviet twin-engined bomber designed during World War II. Only a single prototype had been built before the program was terminated upon the death of Nikolai Nikolaevich Polikarpov, the head of the aircraft's design bureau, in 1944.
The Ilyushin DB-4 or TsKB-56 was a Soviet twin-engined bomber aircraft of the early 1940s. It was a development of the Ilyushin DB-3 and was intended as a replacement for the earlier aircraft, but only two prototypes were built; engine problems and the need to concentrate production on existing types following the German invasion of the Soviet Union in June 1941 meant that no more examples were built.
The Yakovlev AIR-6 was a Soviet light utility aircraft of the 1930s. It was a single-engined high-wing monoplane designed by Alexander Sergeyevich Yakovlev, with 128 being built.
The Yakovlev AIR-7 was a prototype Soviet high performance light aircraft of the 1930s. It was a two-seat single-engined monoplane, which demonstrated excellent performance during testing. After the prototype almost crashed as a result of flutter, its designer, Alexander Sergeyevich Yakovlev suffered temporary disgrace and no production followed.
The Capital Machinery Factory Capital-1 was a twin-engined monoplane light transport/utility aircraft designed and built in the People's Republic of China at Beijing in the late 1950s.
The Yakovlev AIR-12 was a long-range sport aircraft designed and built in the Soviet Union during the late 1930s.
