Rolls-Royce Eagle 22
From Wikipedia, the free encyclopedia
for the First World War era engine, see Rolls-Royce Eagle
The Rolls-Royce Eagle 22 was a 24 cylinder sleeve valve aero engine of 46.2 Litres (2,820 cubic inches) displacement. Produced in the late 1940s it was liquid cooled, of flat H configuration with two crankshafts and capable of 3,200 hp (2,387 kW) at 18 psi boost.
The Eagle was extremely powerful, but was never fitted to a production front-line fighter, as it was overshadowed by a new wave of jet engines, such as the Rolls-Royce Derwent and Nene. Approximately 50 Eagles were produced. It was used in the prototypes of the Westland Wyvern fighter/torpedo bomber.
