The Shvetsov ASh-62 (Russian: АШ-62, designated M-62 before 1941) is a nine-cylinder, air-cooled, radial aircraft engine produced in the Soviet Union. A version of this engine is produced in Poland as the ASz-62 and the People's Republic of China as the HS-5.

Design and development

The ASh-62 was a development of the Wright R-1820 Cyclone that had been built in Russia under licence as the Shvetsov M-25, the main improvements including a two-speed supercharger and a more efficient induction system. Power was increased from the Cyclone's 775 hp to 1,000 hp. First run in 1937, licensed versions are still in production by WSK "PZL-Kalisz" in Poland (as of 2017).Gruszczyński, Jerzy. W pierwszej lidze dostawców, "Lotnictwo Aviation International" Nr. 9/2017, p. 34-37 (in Polish) The Ash-62 was also produced in China. It is estimated that 40,361 were produced in the USSR.

Polish-built ASz-62IR engines (Polish transcription of Russian name), by WSK "PZL-Kalisz" in Kalisz, are compatible with FAR-33 requirements. Further developments in Poland are the K9-AA, K9-BA and K9-BB engines, with take-off power of 1178 hp (860 kW), indicated power 698 kW. From 2015 the ASz-62IR-16E was produced with electronic fuel injection, offering greater power and the possibility of running on commercial automotive fuel.

The M-63 was an improved version of the M-62 with the 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 {{convert|4500|m|ft|abbr=on}} due to a higher compression ratio of 7.2:1 and a higher redline.
