Tumansky R-11 Turbojet Engine
The Tumansky AM-5, designed in 1950, was the first turbojet of entirely Soviet origin produced in quantity. A later version, the AM-9, powered the Mikoyan-Gurevich MiG-19 and Yakovlev Yak-25 aircraft, and, in early 1956, evolved into the R-11, a slightly larger two-shaft engine. The R-11 engine powered the Mikoyan-Gurevich MiG-21 fighter and Yakovlev Yak-28, which the Soviet air force used as a fighter, trainer, and reconnaissance aircraft.
Tumansky developed increasingly powerful versions of this engine. The 60,800 N (13,668 lb) thrust R-11 F2S-300 final production model was also manufactured under license by both India and China. Some 20,000 R-11 engines were manufactured before production ended in 1966.
