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 .
This new airframe later formed the basis for the Rolls-Royce Griffon powered Spitfires. This article presents a history of the Spitfire powered by two-stage engine variants and also describes some of the "drawing board" projects and experimental Spitfires. The Griffon powered variants are described in a separate article.
The Supermarine Seafang was a British Rolls-Royce Griffon–engined fighter aircraft designed by Supermarine to Air Ministry specification N.5/45 for naval use. It was based on the Spiteful, which was a development of Supermarine's Griffon-engined Spitfire aircraft. By that time the Spitfire was a 10-year-old design in a period of rapid ...
Contra-rotating propellers Contra-rotating propellers on the Rolls-Royce Griffon-powered P-51XR Mustang Precious Metal at the 2014 Reno Air Races. Aircraft equipped with contra-rotating propellers (CRP) [1] coaxial contra-rotating propellers, or high-speed propellers, apply the maximum power of usually a single piston engine or turboprop engine to drive a pair of coaxial propellers in contra ...
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 ...
