Overview
The Fiat AS.2 was a liquid-cooled, 12-cylinder V-type piston engine developed by Fiat Aviazione in the mid-1920s, specifically engineered for participation in the 1926 Schneider Trophy seaplane competition.[1]
Design and Development
Created to compete in the 1926 Schneider Trophy race held at Hampton Roads, Virginia, the AS.2 drew significant design influence from the American Curtiss D-12 engine. However, unlike the D-12’s integrated cylinder and head design, the AS.2 utilized separate steel cylinders combined with cast aluminium alloy cylinder heads.[2] Its foundation was based on the earlier Fiat A.22 engine.[3] The letter 'S' in its designation stood for Spinto, meaning thrust. One notable challenge was its use of magnesium alloy pistons—a relatively novel material in engine manufacturing at that time—which led to frequent piston perforations. Despite these mechanical difficulties, the AS.2 achieved a remarkable outcome by securing first place in the Schneider Trophy on 13 November 1926, with another aircraft powered by the same engine model finishing third.[4]
