Kuznetsov NK-6

The Kuznetsov NK-6 was a low-bypass afterburning turbofan engine, designed by the Kuznetsov Design Bureau.

Development
Development of the NK-6 started in 1955 at the Kuznetsov Design Bureau. It was the first afterburning by-pass engine made in the Soviet Union. With a maximum thrust of 216 kN, it was the most powerful jet engine in the world in the early 1960s. Despite this fact, development of the NK-6 was halted in July 1963. The accumulated experience of the NK-6 project was subsequently used in the development of the NK-144.

A modified version of this engine, the NK-7, was intended for the Soviet Navy and had a takeoff thrust of 216 kN.
