Wright R-1510 Whirlwind


During the mid-1930s, Wright also developed two fourteen-cylinder double-row versions of the Whirlwind, the R-1510 (introduced 1933) of 600 hp (450 kW), and the R-1670 of 800 hp (600 kW). These were used in a number of military aircraft prototypes, but neither engine reached the production stage.
