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.
When Airbus launched its A330 twin-jet in June 1987, its only engine options included the General Electric CF6-80C2 and the Pratt & Whitney PW4000. [4] Rolls-Royce was studying whether to launch a RB211-700, 65,000 lbf (290 kN) development of the RB211 for the A330, the long-range Boeing 767 and McDonnell Douglas MD-11, derived from the Boeing 747-400's -524D4D, with growth potential to 70,000 ...
The UK government granted Rolls-Royce £450 million of repayable launch investment, repaid with interest, to develop the RB.211 engine and the Trent family up to the Trent 900. [8] Rolls-Royce obtained £200 million for the Trent 8104, 500 and 600 variants in 1997, and £250 million for the Trent 600 and 900 variants in 2001.
Rolls-Royce took over Bristol Siddeley in 1967 so the configuration for the RB199 was decided jointly, a three-shaft engine. The overall design concept for the international collaborative program, three shafts and a bypass ratio (BPR) of about 1.2, was decided by Rolls-Royce. The bypass ratio was chosen for long-range, with low fuel consumption ...
The Tu-204 was designed as a family of aircraft incorporating passenger, cargo, combi and quick-change variants. It is powered by either two Aviadvigatel PS-90 or Rolls-Royce RB211 engines. The Tu-204 is produced at two of the largest Russian aircraft manufacturing plants in Ulyanovsk (Tu-204 series) and Kazan (Tu-214). [8]
Rolls-Royce went on to develop the high-thrust RB211-524 for the L-1011-200 and -500, but this took many years. [25] The resultant delay in Lockheed and Rolls-Royce offering a high gross variant with a longer range, coupled with the TriStar's delayed introduction, meant that only 250 TriStars were sold compared to over 400 DC-10s.
