Tumansky RD-9
The Tumansky RD-9 (initially designated Mikulin AM-5) was an early Soviet turbojet engine, one of the first not based on pre-existing German or British designs. The AM-5, developed by scaling down the AM-3, was available in 1952 and completed testing in 1953; it produced 25.5 kN (5,700 lbf) thrust without afterburner.
