Rolls-Royce produced a range of piston engine types for aircraft use in the first half of the 20th century.
Examples of Rolls-Royce aircraft piston engine types remain airworthy today with many more on public display in museums.
The Buzzard was an enlargement of the Kestrel [3] of Condor size, developed in its most extreme form into the Rolls-Royce R racing engine used for the Schneider Trophy competition.
[9] However the successful development of the Merlin and Griffon, and the introduction of jet engines precluded significant production of these types.
Production of Rolls-Royce designed aircraft piston engines ceased in 1955 with the last variants of the Griffon.
