The Rolls-Royce Griffon is a British 37-litre (2,240 cu in) capacity, 60-degree V-12, liquid-cooled aero engine designed and built by Rolls-Royce Limited. In keeping with company convention, the Griffon was named after a bird of prey , in this case the griffon vulture .
A preserved Rolls-Royce Griffon 58, one of the last Rolls-Royce piston engines to be produced. The red and white "dumb bell" object to the left of the engine is an air raid siren exhibit Rolls-Royce produced a range of piston engine types for aircraft use in the first half of the 20th century.
The first Griffon-powered Spitfires suffered from poor high altitude performance due to having only a single stage supercharged engine. By 1943, Rolls-Royce engineers had developed a new Griffon engine, the 61 series, with a two-stage supercharger. In the end it was a slightly modified engine, the 65 series, which was used in the Mk XIV.
The Rolls-Royce Merlin and Griffon engines [ edit ] A key factor which allowed the continued development of the Spitfire was the development of progressively more powerful and improved engines, starting with the Rolls-Royce Merlin and progressing to the bigger and more powerful Rolls-Royce Griffon .
The Supermarine Spiteful was a British fighter aircraft designed by Supermarine during the Second World War as a successor to the Spitfire.Powered by a Rolls-Royce Griffon engine, it had a radical new wing design to allow safe operations at higher speeds and incorporating inwards-retracting undercarriage.
The early Spitfire variants powered by the Rolls-Royce Griffon were adaptations of Mk Vc (early Mk XII) or Mark VIII (late Mk XII and Mk XIV) airframes. The later Griffon-engined Spitfire variants embodied new wings, tail units and undercarriages and were very different from any of the earlier Spitfire marks.
The experience gained by Rolls-Royce and Supermarine designers from the R engine was invaluable in the subsequent development of the Rolls-Royce Merlin engine and the Spitfire. A de-rated R engine, known as the Griffon , was tested in 1933, but it was not directly related to the production Rolls-Royce Griffon of 1939, of the same exact bore ...
