accepted an official request to create a new engine that would later be designated as the NK-22.
The design of the NK-22 was based on the
NK-144 engine used on the
Tupolev Tu-144
The Tupolev Tu-144 (russian: Tyполев Ту-144; NATO reporting name: Charger) is a Soviet supersonic passenger airliner designed by Tupolev in operation from 1968 to 1999.
The Tu-144 was the world's first commercial supersonic transport ai ...
SST.
The first specimen of the engine was completed on April 10, 1968
and the first factory tests where passed in the same month.
State tests took place in October 1970.
The engines where later installed on
Tu-22M0, M1 and M2 bombers.
Serial production of the NK-22 started in 1969 and was terminated in 1984.
A modernised version of the NK-22, the NK-23, first ran in July 1976
and was tested in flight on a
Tupolev Tu-22M2 bomber.
Despite having more thrust (220 kN)
than its predecessor, the NK-23 was not put into serial production.
