The Wright R-3350 Duplex-Cyclone is an American air cooled radial piston engine developed in the early 1940s, most famously powering the Boeing B-29 Superfortress bomber. It later powered postwar airliners such as the Lockheed Super Constellation and the Douglas DC-7 before piston engines gave way to jets on major airline routes.
