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 .
7-678: 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). The Ash-62
14-629: Is an American radial engine developed by Curtiss-Wright , widely used on aircraft in the 1930s through 1950s. It was produced under license in France as the Hispano-Suiza 9V or Hispano-Wright 9V , and in the Soviet Union as the Shvetsov M-25 . The R-1820 Cyclone 9 represented a further development of the Wright P-2 engine dating back to 1925. Featuring a greater displacement and a host of improvements,
21-662: The M-25 , with the R-1820's general design features used by the Shvetsov design bureau for many of their future radials for the Soviet air forces through the 1940s and onwards. In Spain the R-1820 was license-built as the Hispano-Suiza 9V or Hispano-Wright 9V . The R-1820 was at the heart of many famous aircraft including early Douglas airliners (the prototype DC-1 , the DC-2 , the first civil versions of
28-724: The DC-3 , and the limited-production DC-5 ), every wartime example of the Boeing B-17 Flying Fortress and Douglas SBD Dauntless bombers, the early versions of the Polikarpov I-16 fighter (as the M-25), and the Piasecki H-21 helicopter. The R-1820 also found limited use in armoured vehicles. The G-200 variant developed 900 hp (670 kW ) at 2,300 rpm and powered the strictly experimental M6 Heavy Tank . The Wright R-1820
35-605: The R-1820 entered production in 1931. The engine remained in production well into the 1950s. The R-1820 was built under license by Lycoming , Pratt & Whitney Canada , and also, during World War II , by the Studebaker Corporation . The Soviet Union had purchased a license for the design, and the Shvetsov OKB was formed to metricate the American specification powerplant for Soviet government-factory production as
42-660: 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
49-586: 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 4,500 m (14,800 ft) due to a higher compression ratio of 7.2:1 and a higher redline.
