The Rolls-Royce Eagle was a 24-cylinder, sleeve valve, H-block aero engine of 46 litre (2,807 cubic inches) displacement. It was designed and built in the late 1940s by Rolls-Royce Limited. It was liquid cooled, of flat H configuration with two crankshafts and was capable of 3,200 hp (2,387 kW) at 18 psi boost.
The Eagle was never fitted to a production front-line fighter, as it was overshadowed by a new wave of turbojet engines, such as the Rolls-Royce Derwent and turboprops such as the Dart and Armstrong Siddeley Python. Approximately 50 Eagles were produced. It was used in the prototypes of the Westland Wyvern fighter / torpedo bomber.
