The Shvetsov ASh-82 (M-82) is a 14-cylinder, two-row, air-cooled radial aircraft engine developed from the Shvetsov M-62. The M-62 was the result of development of the M-25, which was a licensed version of the Wright R-1820 Cyclone.

Design and development

Arkadiy Shvetsov re-engineered the Wright Cyclone design for Russian aviation engine manufacturing practices and metric dimensions and fasteners, reducing the stroke, dimensions and weight. This allowed the engine to be used in light aircraft, where a Twin Cyclone could not be installed.[1] It entered production in 1940 and saw service in a number of Soviet aircraft. It powered the Tupolev Tu-2 and Pe-8 bombers and the inline engine-powered LaGG-3 was adapted for the ASh-82 producing the famous Lavochkin La-5 fighter and its development, Lavochkin La-7, additionally the Lavochkin La-9 with its Lavochkin La-11 escort variant and Ilyushin Il-14 airliner were created around the engine. Over 70,000 ASh-82s were built. They were built in fifties to sixties under licence also in Czechoslovakia (as the M-82) by the Walter (Motorlet) factory in Prague-Jinonice and in the German Democratic Republic by the VEB Industriewerke Karl-Marx-Stadt.

Variants
