- Rolls-Royce Eagle
:"For the 1940s engine, see
Rolls-Royce Eagle (1944) "The Rolls-Royce Eagle was an aero-engine developed during the
First World War by Rolls-Royce that was used to power a number of military aircraft.Design and development
The design was a liquid cooled V12 engine with the cylinders inclined at 60 degrees and the valves driven by overhead
camshaft s. It first ran in 1915. Bore and stroke were 4.5 inches by 6.5 inches (115 x 165 mm) giving a 20litre capacity. The whole engine weighed 900 lb (408 kg) producing 360 hp (268 kW) at 1800 rpm.Production ran until 1928 by which point 4,681 had been built. [Lumsden 2003, p.183.]
There is an example of this engine in the Science Museum,
London .Applications
