- Shvetsov ASh-62
__NOTOC__The
Shvetsov ASh-62 (designated M-62 before 1941) is a nine-cylinder, air-cooled, radialaircraft engine produced in theSoviet Union . It was a development of theWright Cyclone that had been built there under licence as theShvetsov M-25 , the main improvements including a two-stage supercharger and a more efficient induction system. Power was increased from the Cyclone's 775 hp to 1,000 hp. First run in 1937, licenced versions are still in production by WSK "PZL-Kalisz" in Poland as the ASz-62 (as of 2007). The Ash-62 was also produced in China. It is estimated that 40,361 were produced in the USSR.Polish-built ASz-62IR are compatible with FAR-33 requirements. Further development in Poland are K9-AA, K9-BA and K9-BB engines, with take-off power 1178 hp (860 kW), indicated power 698 kW. The K9-BA engine might be fitted to
DC-3 Dakota .M-63 was an improved version of M-62 with power output increased to 821 kW (1,100 hp) at 2,300 rpm for takeoff and 671 kW (900 hp) at 2,200 rpm at 4,500 m (14,764 ft) thanks to a greater compression ratio of 7.2:1 and a higher redline.
