Tumansky RD-9

The Tumansky RD-9 is a Soviet turbojet engine, originally designated as AM-5, developed in the early 1950s by the Tumansky Design Bureau. This engine powered several prominent Soviet aircraft, including the MiG-19. The RD-9 was a single-shaft turbojet with an axial compressor and an annular combustion chamber. It had a thrust output of approximately 25.5 kN in its early variants, which was later increased to around 31.9 kN in the RD-9B version. The engine featured an afterburner, significantly boosting its thrust during combat situations. Known for its reliability and performance, the RD-9 contributed to the MiG-19's status as one of the first mass-produced supersonic fighters.
