The Wright R-975 Whirlwind was a series of nine-cylinder air-cooled radial aircraft engines built by the Wright Aeronautical division of Curtiss-Wright.These engines had a displacement of about 975 cu in (15.98 L) and power ratings of 300–450 hp (220–340 kW).
Wright's J-1 was the first engine in its nine-cylinder R-790 Whirlwind series and was quickly followed by the J-3, J-4, J-4A, J-4B, and finally the popular and successful J-5 of 1925. In 1928, Wright replaced the R-790 series with the J-6 Whirlwind family, in which a supercharger was added to boost engine power and the cylinders were enlarged ...
The Wright R-790 Whirlwind was a series of nine-cylinder air-cooled radial aircraft engines built by Wright Aeronautical Corporation, with a total displacement of about 790 cubic inches (12.9 L) and around 200 horsepower (150 kW). These engines were the earliest members of the Wright Whirlwind engine family.

The BT-14 featured a Pratt & Whitney R-985 engine versus the Wright R-975 used on the BT-9. As well as metal skin replacing the fabric on the fuselage, the fin was moved aft slightly, lengthening the rear fuselage while the engine was moved forward to maintain the center of gravity. The rudder was also changed from the rounded shape used ...
