Rolls-Royce Peregrine Rolls-Royce Peregrine The Rolls-Royce Peregrine was a , liquid-cooled V-12 aero engine designed and built by the British manufacturer Rolls-Royce in the late 1930s. It was essentially the ultimate development of the company's Kestrel engine, which had seen widespread use in military aircraft of the pre-war period. Due to the wartime priority of Rolls-Royce Merlin development and production, the Peregrine saw limited use and was cancelled with only 301 engines being built. During the 1930s the use of superchargers to increase "effective displacement" of an aircraft engine came into common use. Charging of some form was a requirement for high-altitude
Rolls-Royce RB162 change from vertical to horizontal installation. With the RB162 fitted the Trident 3B had a 15% increase in thrust over the earlier variants for an engine weight penalty of only 5%. A design study for a turbofan version of the RB162 was designated RB175. Another projected derivative, the RB181 was to be a scaled-down version of the RB162 producing approximately 2,000 lbs of thrust. Seven of these lift engines were to power the unbuilt Lockheed/Short Brothers CL-704 VTOL variant of the F-104 Starfighter.
