Shvetsov ASh-62

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).[1] 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.[1]

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 4,500 m (14,764 ft) due to a higher compression ratio of 7.2:1 and a higher redline.

gollark: "If they start doing stuff you don't want with it, you just have to hope someone notices and stops it, but it might stop transactions you actually want to make randomly anyway."
gollark: "Ah yes, you need to give someone these numbers to make a transaction, and they're literally all written on the card anyway, and if they have the numbers they can arbitrarily make any amount of transactions they want."
gollark: I don't like bitcoin generally, but... well, you have to explicitly make a transaction, what moron designed credit cards?
gollark: Credit cards are a stupid system anyway.
gollark: Alternatively, you can read it as "basically semantics and complaining about people who do not like their stuff tested on".
