Wright Cyclone series
Wright Cyclone was the name given to a family of air-cooled radial piston engines designed by the Wright Aeronautical Corporation and used in numerous American aircraft in the 1930s, 1940s and 1950s.
BackgroundEdit
The Wright Aeronautical Corporation was formed in 1919, initially to develop liquid-cooled Hispano-Suiza V8 engines under license.Template:Sfn In 1923 the Wright purchased the Lawrance Aero Engine Company, and with the purchase Charles Lawrance came to Wright as the Vice-President.Template:Sfn Later that year the US Navy awarded Wright a contract to develop two new air-cooled radial engines. The first, called the P-1, was a 9-cylinder single row design of Template:Cvt displacement that was derived from an earlier Lawrence design, it produced Template:Cvt.Template:Sfn The second, the P-2, had the same Template:Cvt displacement as the P-1, but was an improved design that produced Template:Cvt.Template:Sfn Neither engine entered production, with the Navy selecting the superior Pratt & Whitney R-1340 Wasp, so in 1926 work started on the improved Template:Cvt design, which became the R-1750 Cyclone.Template:Sfn
