The Fiat AS.2 was an Italian 12-cylinder, liquid-cooled V engine designed and built in the mid-1920s by Fiat Aviazione especially for the 1926 Schneider Trophy air race.[1]

Design and development

Designed for the 1926 Schneider Trophy contest held at Hampton Roads, Virginia, the AS.2 was inspired by the American Curtiss D-12 engine. Unlike the D-12 the engine featured separate steel cylinders and cast aluminium alloy cylinder heads.[2] The starting point for the Italian engine was the earlier Fiat A.22.[3] The 'S' in AS stood for 'Spinto' (thrust). A weakness of the engine was its magnesium alloy pistons, a new engineering material at the time. Many pistons were holed. Despite the engine's technical problems it was successful at the Schneider Trophy event, winning on 13 November 1926, with a second AS.2 powered aircraft placing third.[4]
