Schwezow ASch-62
The Schwezow ASch-62 ( Russian Швецов АШ-62 , before 1941 referred to as M-62 ) is an air-cooled nine-cylinder radial engine that was manufactured in the Soviet Union . One version of this engine is manufactured in the People's Republic of China as the HS-5 . The name refers to the initials of its designer Arkadi Schwezow .
construction and development
The ASch-62 is an air-cooled nine-cylinder gasoline engine with a star-shaped piston arrangement. It is a further development of the Wright R-1820 Cyclone , which was manufactured under license in the Soviet Union as the Schwezow M-25 . The main improvements included a two-stage compressor and a more powerful suction system. This increased the maximum output from 570 to around 746 kW . The engine was put into operation for the first time in 1937 and is still manufactured today (as of October 2015) as ASz-62IR in Kalisz (Poland) by WSK "PZL-Kalisz" . It is estimated that over 40,000 engines were built in the Soviet Union.
With the successor variant M-63, an increase in the compression ratio (7.2: 1) and the maximum permissible number of revolutions increased the maximum power to 809 kW.
