Mikulin AM-35

From Wikipedia, the free encyclopedia

The Mikulin AM-35 was a 1930s Soviet aircraft piston engine. Derived from the AM-34FRN, AM-35 entered production in 1940 and was used on MiG-1 and MiG-3 World War II fighters as well as the Petlyakov Pe-8 heavy bomber. The engine was very similar to AM-38F the of the Ilyushin Il-2 Shturmovik, and built in the same plant (Kuybyshev, in late 1941). It was for this fact that Mikulin was forced to focus production on the AM-38F, thus discontinuing construction of the AM-35.
