context_page_description: Rolls-Royce produced a range of piston engine types for aircraft use in the first half of the 20th Century. Production of own-design engines ceased in 1955 with the last versions of the Griffon; licensed production of Teledyne Continental Motors general aviation engines was carried out by the company in the 1960s and 1970s.
  Examples of Rolls-Royce aircraft piston engine types remain airworthy today with many more on public display in museums.
context_section_description: 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.
