The Wright R-540 Whirlwind was a series of five-cylinder air-cooled radial aircraft engines built by the Wright Aeronautical division of Curtiss-Wright, with a displacement of 540 cubic inches (8.85 litres) and power ratings of about 165 to 175 horsepower. It was the smallest member of the Wright Whirlwind family. Wright introduced the J-6 Whirlwind family in 1928 to replace the nine-cylinder R-790; the five-cylinder version began as the J-6-5 and took the government designation R-540, which Wright then adopted. It had a larger bore than the R-790 and a gear-driven supercharger. Designed for light aircraft, it powered types such as the Curtiss Robin, and over 400 were built in 1929 before Depression-era sales fell away. Wright ended five-cylinder Whirlwind production in 1937, leaving the small radial market to firms such as Kinner and Warner. It was also built in Spain as the Hispano-Suiza 5Q.
