The Tumansky R-11 (initially AM-11) is a turbojet engine.
The Tumansky R-11 was developed by A.A. Mikulin, S.K. Tumansky, and B.S. Stechkin as a twin-spool axial-flow high-altitude non-afterburning turbojet for Yakovlev Yak-25RV reconnaissance aircraft. This engine was the first Soviet twin-spool turbojet. It was first run in early 1956. The basic design was very successful and it was evolved into Tumansky R-13 and Tumansky R-25. Also experimental Tumansky R-21 was an evolution of R-11. A total of 20,900 R-11 engines were built.
