The Wright R-1820 Cyclone

The Wright R-1820 Cyclone roared beneath the wings of some of the most iconic aircraft of the 20th century. Think Boeing B-17 Flying Fortress or the sleek Sikorsky H-34. Beyond these, the Cyclone lent its power to the Curtiss P-36 Hawk, Douglas B-18 Bolo, Douglas DC-3, Douglas SBD Dauntless, and the General Motors FM-2 Wildcat.
