Rolls-Royce RB211

The Rolls-Royce RB211 is a family of high-bypass turbofan engines made by Rolls-Royce plc and capable of generating 37,400 to 60,600 pounds-force (166 to 270 kilonewtons) 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. Its RB211 engine was the first three-spool engine, and it was to turn Rolls-Royce from a significant player in the aero-engine industry into a global leader. Already in the early 1970s the engine was reckoned by the company to be capable of at least 50 years of continuous development.
