The Pratt & Whitney R-2270 was an American air-cooled radial aircraft engine. Displacing 2,270 cu in (37.2 L), it was Pratt & Whitney's first two-row radial engine,[1] developed using parts from existing Wasp and Hornet engines to produce an experimental engine.[2] Design of the engine was begun in January 1929;[2] it first ran on May 14, 1930, and in April 1931[2] was test-flown in a Boeing Model 40B aircraft.[1] The R-2270 was intended as a purely experimental engine;[2] studies indicated a smaller engine would be more favored by the market,[1] and Pratt & Whitney began development of the R-1830 engine in April 1931.[2]
