Rolls-Royce Eagle

The Engine Specifications
 
Early in World War I, the British Admiralty asked Rolls-Royce to develop a 200 hp aircraft engine.  Like many engines of the time, Rolls-Royce's design was strongly influenced by Mercedes.  The prototype Eagle was first run in 1915 and was soon producing 225 hp.

The Eagle was subjected to constant improvement; the Eagle VIII was producing 350 hp by 1917.  In the immediate post-war period, this engine was the leading British engine for large aircraft.  The Eagle powered the first direct transatlantic flight as well as the first flight from England to Australia both in the Vickers Vimy aircraft.
