- Summary
- Several former engineers of the failed Franklin Automobile Company formed Air Cooled Motors in 1935. By 1938 a range of flat-4 and 6 aircraft engines was being produced, retaining the Franklin name. This post-war product was the largest model. In 1975, the company disbanded and sold all rights to the Polish government, becoming part of PZL, an association of Polish aero and engine manufacturers. Following the 1989 fall of Communism, the firm became WSK PZL – Rzeszów.
- This is an early vertically-mounted, fan-cooled helicopter engine. The Aircooled Motors (Franklin) O-405-9 was installed in the Sikorsky XH-6A, YH-6A, H-6A, YH-6, Sikorsky XH-7, Kellett XH-8, and XH-8A helicopters. The Franklin designation for this engine was 6ACV-403.
