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.
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 ...

Wright Aeronautical (1919–1929) was an American aircraft manufacturer headquartered in Paterson, New Jersey. [1] It was the successor corporation to Wright-Martin. [1] It built aircraft and was a supplier of aircraft engines to other builders in the golden age of aviation. [1]
In 1929 one clipped-wing Phaeton was tested as a racer, then fitted with 200–220 hp (150–160 kW) nine cylinder R-790 Whirlwind engine. Piloted by Jack Foster, this competed in the 1930 National Air Races, resulting in the sale of another 24 similarly-powered, though full span, Phaetons. [3] American Eagle ceased trading in 1932. [4]
The Wright R-760 Whirlwind was a series of seven-cylinder air-cooled radial aircraft engines built by the Wright Aeronautical division of Curtiss-Wright. These engines had a displacement of 756 in³ (12.4 L) and power ratings of 225-350 hp (168-261 kW).
Two-seat primary trainer biplane, powered by a 220 hp (160 kW) Wright R-790 Whirlwind (J-5) radial piston engine. 179 were built. XN3N-2 One prototype only (Bureau number 0265) powered by a 240 hp (180 kW) Wright R-760-96 Whirlwind (J-6-7) radial piston engine. XN3N-3 One production N3N-1 (0020) converted into a 'dash three' prototype. N3N-3
This was made into a fighter simply by covering over the front cockpit of the observation plane, mounting machine guns in that area, and upgrading to a 220 hp (160 kW) Wright R-790 Whirlwind with a supercharger. With the help of the supercharger, the newly designated FU-1 was able to reach a speed of 147 mph (237 km/h) at 13,000 ft (4,000 m).
