|Preserved D-12 engine|
The Curtiss D-12 was an aero engine of 18.8 litres capacity. It was a water-cooled V12, producing 443 hp (330 kW) and weighing 693 lb (314 kg). It was designed by Arthur Nutt in 1921 and used in the Curtiss CR-3 for the 1923 Schneider Trophy race. Fairey Aviation of England imported 50 Curtiss built examples in 1926, renaming them the Fairey Felix.
The D-12 was one of the first truly successful aluminum cast-block engines, and was extremely influential in the inter-war period. Numerous subsequent engines trace their design to the D-12, among them the Packard 1A-1500, Rolls-Royce Kestrel and Junkers Jumo 210.
