Rolls-Royce Aircraft Piston Engines - Inter-war Years

Inter-war Years

The Kestrel was a post-war redesign of the Eagle featuring wet cylinder liners in (two) common cylinder blocks. It was developed into the supercharged Peregrine and later the Goshawk.

Developed concurrently with the Kestrel was the unusual Rolls-Royce Eagle XVI X engine that was cancelled in favour of the Kestrel despite performing well on the test stand.

The Buzzard was an enlargement of the Kestrel of Condor size, developed in its most extreme form into the Rolls-Royce R racing engine used for the Schneider Trophy competition.

The Vulture of 1939 was essentially two Peregrines on a common crankshaft in an X-24 configuration, both of these types being deemed unsuccessful.
