The Bartini T-117 was a Soviet transport aircraft designed by Robert Lyudwigowitsch Bartini that was not built in series.
history
From 1944 to 1948 Bartini worked on the T-117, which first had the project name P-7. The aircraft was designed as a passenger aircraft and also in a cargo aircraft version. The cargo aircraft version had a tailgate with a loading ramp. The aircraft was a high- wing aircraft, each with a Schwezow ASch-73 18-cylinder radial engine with 2400 hp and a four-blade propeller. The main landing gear had two wheels and went into the engine pod. The wings, the engine and the arrangement of the main landing gear are comparable to the Antonov An-26 . The T-117 had an elevator with a triple vertical stabilizer, one vertical stabilizer each at the end of the horizontal stabilizer and one in the middle. The tail units at the ends of the horizontal stabilizers were one third below the level of the horizontal stabilizer. The configuration of the elevator and rudder unit is comparable to that of the Lockheed Super Constellation . The fuselage was elliptical in cross-section with the major axis horizontal. The T-117 was thus the first Soviet "wide body" aircraft . The transport version could transport up to 8000 kg. The rear loading ramp made it possible to transport motorcycles, guns up to 122 mm caliber, mortars, trucks and jeeps. The wide fuselage made it possible to transport two GAZ-67 jeeps side by side in two rows . Alternatively, up to 80 soldiers could be transported on four benches along the ship's side and the middle of the fuselage. For the passenger version, various cabin designs for up to 50 passengers were developed with a range of up to 1600 km and a cruising speed of 365 km / h.
Construction of the prototype began in 1946, but was stopped in 1948 because the ASch-73 engines were needed for the Tupolev Tu-4 . At that time, the Tu-4 had absolute priority due to a personal order from Josef Stalin . Therefore, plans were made for the use of alternative engines, such as the ASch-82FN , the experimental ASch-2 four-row radial engine or the 353 kW (480 PS) Klimow WK-2 turboprop engine. All of this was unsuccessful. The only T-117 built was never equipped with engines and was scrapped. The tasks for which the T-117 was intended in the military sector were later taken over by the An-8 .
