Mikulin AM-3

The Mikulin AM-3 (also called RD-3M) was a turbojet engine developed in the Soviet Union by Alexander Mikulin.

Design and development

The development of the high-performance single-shaft engine began in 1948. The engine was used in different versions for the Tupolev Tu-16 and Tu-104, as well as the Myasishchev M-4. It had a single-stage low-pressure and an eight-stage high-pressure compressor, powered by a two-stage high-pressure turbine.
