Rolls-Royce R revolutions. Although not directly related to the Spitfire, the Supermarine engineers gained valuable experience of high-speed flight with the S.5 and S.6 aircraft, their next project being the Rolls-Royce Goshawk-powered Supermarine Type 224 prototype fighter aircraft. Technological advances used in the R engine, such as sodium-cooled valves and spark plugs able to operate under high boost pressures, were incorporated into the Rolls-Royce Merlin design. The author Steve Holter sums up the design of the Rolls-Royce R with these words: The Schneider Trophy was a prestigious annual prize competition for seaplanes that was first held in 1913. The 1926 race was
Rolls-Royce RB211 Rolls-Royce RB211 The Rolls-Royce RB211 is a British family of high-bypass turbofan engines made by Rolls-Royce plc. Mismanagement of the initial development and consequent cost issues led to the effective nationalisation of Rolls-Royce Limited, in order to save the workforce and the engine businesses important to the nation and many other aerospace and aircraft operating companies. The engines are capable of generating of thrust. Originally developed for the Lockheed L-1011 TriStar, it entered service in 1972 and was the only engine to power this type of aircraft. The RB211 engine was the first production three-spool engine, and it was to
