Wright R-760
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 in the 1930s. These engines had a displacement of 756 in³ (12.4 L) and a power rating of up to 350 hp (261 kW).[1]

Design and development
Wright first introduced the J-6 Whirlwind family in 1928. This family, which had larger cylinders than the previous J-5, originally included varieties with seven and nine cylinders. In 1929, Wright introduced a seven-cylinder version, designated as R-760 by the US government.
Wright expanded the cylinder bore to 5.0 in (127 mm). The first engine of this series, the R-760, had fewer cylinders than the older Whirlwinds but was similar in displacement and power. Wright later followed it with the larger nine-cylinder R-975 and the smaller five-cylinder R-540, providing a range of power levels while using the same basic design.
Variants
- J-6-7 (R-760): 225 hp (168 kW) at 2,000 RPM.
- R-760E: 250 hp (186 kW) at 2,000 RPM. Higher power from improved cylinder head.
- R-760E-1: 285 hp (213 kW) at 2,100 RPM. Higher compression ratio.
- R-760E-2: 320 hp (239 kW) at 2,200 RPM, 350 hp (261 kW) at 2,400 RPM for takeoff. Increased supercharging, slightly higher compression ratio.
- R-760E-T: 235 hp (175 kW) at 2,000 RPM. Unsupercharged version of R-760E-1 for trainer aircraft.
