Tumansky R-11 Turbojet Engine

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

Transferred from the United States Air Force.
