Mikulin AM-3

The Mikulin AM-3 (also known as RD- 3M) is a system developed in the Soviet Union by the designer Alexander Alexandrovich Mikulin turbojet engine, which was used from 1952.

The development of high-performance single- engine began in 1948. 1947 a delegation of Soviet engine specialist at Rolls -Royce were the engines Nene and Derwent shown. During this visit Mikulins mitgereister deputy Subzow got to see with axial compressor accidentally parts of the new Avon engine. This was new, as is often claimed, not, as they had for the Russians in 1946 on patterns of German engine Junkers 012, which corresponded to the then Avon in the interpretation and performance. Subzow now developed during the year 1948 its own axial compressors for future AM- third Mid-year 1949, the development work was completed, at the end were the finished drawings before and after 1950 began series production.

Was used the engine in different versions for the types of aircraft Tupolev Tu -16 and Tu- 104 and M- Mjassischtschew fourth It had a single stage fan, and an eight -stage high- pressure compressor, which was powered by a two-stage high pressure turbine. Developed with the help of similarity theory Mikulin from the AM -3 shortly after the proportionally reduced AM -5 ( also RE -5 ), which was finished in 1950 and produced from 1953. It was ( again modified and now referred to as Tumanski RD -9), for example, in the Yak- 25 and used in the MiG -19.
