The Rolls-Royce RB211 is a British family of high-bypass turbofan engines made by Rolls-Royce. The engines are capable of generating 41,030 to 59,450 lbf (182.5 to 264.4 kN) of thrust . The RB211 engine was the first production three-spool engine and turned Rolls-Royce from a significant player in the aero-engine industry into a global leader.
[132] [133] The first engine to power the 757-200, the Rolls-Royce RB211-535C, was succeeded by the upgraded RB211-535E4 in October 1984. [134] Other engines used include the Rolls-Royce RB211-535E4B, along with the Pratt & Whitney PW2037 and Pratt & Whitney PW2000-37/40/43. [28] Its range with full payload is 3,850 nautical miles (7,130 km ...
In December 1980, Pratt & Whitney changed to a new naming system for its engines and the JT10D became the PW2037. The PW2000 is a dual-spool, axial air flow, annular combustion, high bypass turbofan with a dual-channel full authority digital engine control system. It was certified in 1984 as the first civilian FADEC-controlled aviation engine.
The following is a list of current Boeing 757 operators. There were 572 aircraft on operator registries as of December 2024 [update] ; 520 757-200s and 52 757-300s. Of the 572 aircraft, the status of 525 were listed as active, with 47 aircraft listed as parked.
A large order by Iran Air Tours is under threat because of sanctions against the Iranian economy, as the American company Pratt & Whitney has been involved in the development of the engine with the Perm Engine Company. Completing the sale by re-equipping the Tu-204SMs with the Tu-204's Russian-made PS-90A engines has been proposed. [27]
The Merlin was a powerful supercharged V12 engine and was fitted into many World War II aircraft: the British Hawker Hurricane, Supermarine Spitfire, de Havilland Mosquito (twin-engine), Avro Lancaster (four-engine) (a development of the Avro Manchester with its unreliable Rolls-Royce Vulture engines), Vickers Wellington (twin-engine); it also ...
The engine first ran in 1950 and quickly outperformed its design goals. [5] Initially used in the Vulcan, later versions added reheat for use in the supersonic BAC TSR-2. Bristol Aero Engines merged with Armstrong Siddeley Motors in 1959 to form Bristol Siddeley Engines Limited (BSEL), which in turn was taken over by Rolls-Royce in 1966.
Some info in a 1971 Flight editorial on the receivership here: - apparently airlines offered to pay an additional £80,000 per-engine on top of the original stated price to prevent the RB211's loss. ...and the rest of the article here; [3] — Preceding unsigned comment added by 80.7.147.13 ( talk ) 12:48, 26 July 2012 (UTC) [ reply ]
