|} The Mikulin AM-37 was a Soviet aircraft piston engine designed prior to Russia's entry into World War II. An improved version of the Mikulin AM-35 V-12 engine, it was only produced in small numbers because of its unreliability.

Development

Design work on a development of the AM-35 with boosted supercharging and an intercooler positioned behind the supercharger began on the factory's initiative in December 1939. A batch of ten prototypes was completed in 1940 and bench-testing began on 5 January 1941. It passed its State acceptance trials the following April and was approved for production. It was tested in a variety of aircraft, but proved to be unreliable and prone to overheating. Factory No. 24 in Moscow built only twenty-nine AM-37s, as the new engine was designated, in 1941 before the German advance forced the factory to evacuate in October. Mikulin had been unable to resolve the issues with the AM-37 in the meantime and production was not resumed.[1]
