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.

Famous quotes containing the word years:
“Competition is. In every business, no matter how small or how large, someone is just around the corner forever trying to steal your ideas and build his success out of your imagination, struggling after that which you have toiled endless years to secure, striving to outdo you in each and every way. If such a competitor would work as hard to originate as he does to copy, he would much more quickly gain success.”
—Alice Foote MacDougall (1867–1945)
