Development

Development of the TV-022 began in 1947[2] at the State Union Experimental Plant No. 2 near Kuybyshev.[3] A team of both Soviet and deported German engineers worked on the project.[3]

The TV-022 was based on the uncompleted Junkers Jumo 022 turboprop designed by Junkers during the later stages of World War II.[2]

Factory tests of the TV-022 took place in June 1949[1] and state tests where passed in October 1950.[1] The TV-022 featured a reduction gearbox (i=0.145)[1] for two coaxial contra-rotating AB-41 propellers.[1] The engine was started with a 50 kW "Rut" air starter.[1]

Modifications to the TV-022 resulted in the TV-2, which had more power (6,250 hp).[1] The TV-2 was then further modified into the NK-12.[2]
