Factory tests of the TV-022 took place in June 1949
and state tests where passed in October 1950.
The TV-022 featured a reduction gearbox (i=0.145)
for two
coaxial contra-rotating AB-41 propellers.
The engine was started with a 50 kW "Rut" air starter.
Modifications to the TV-022 resulted in the
TV-2, which had more power (6,250 hp).
The TV-2 was then further modified into the
NK-12.
