RAF.8 design proposal of 1916. The RAF.8 was the work of a design team led by F.M. Green, and incorporated the findings of research into aluminium air-cooled cylinders by Samuel D. Heron and
Professor A. H. Gibson. Disillusioned by political and press criticism of the Royal Air Factory, Green and his

Initial performance was not as expected; as a result the stroke was increased to 5.5 in (139.7 mm) on all variants after the Jaguar I. By that time, the engine had been fitted with a gear-driven

into effective service, an engine that had been ordered in large numbers despite a lack of testing. As a result, the RAF.8 design, then known as the Jaguar, was not run until 21 June 1922.
