The Rolls-Royce Pegasus is a British turbofan engine originally designed by Bristol Siddeley. It was manufactured by Rolls-Royce plc. The engine is not only able to power a jet aircraft forward, but also to direct thrust downwards via swivelling nozzles. [1] Lightly loaded aircraft equipped with this engine can manoeuvre like a helicopter.
Sporting a retractable tricycle landing gear and low wing arrangement, this modern aircraft is powered by a Rolls-Royce M250 340 kW turboprop engine, achieving a maximum speed of 354 km/h, a range of 1,000 km, and a service ceiling of approximately 6,500 m.
Rolls-Royce Trent 970s were the first engines to power the new Airbus A380. The famous thrust vectoring Pegasus – actually a Bristol Siddeley design taken on by Rolls-Royce when they took over that company – is the primary powerplant of the Harrier "Jump Jet" and its derivatives.
Bristol Siddeley had under development another vectored thrust turbofan, the "plenum chamber burner" (similar to an afterburner) equipped BS100, which was intended for the supersonic Hawker Siddeley P.1154 VSTOL fighter, but the project was cancelled in 1965. The two shaft BS143 was proposed for the MRCA (later the Tornado), but the takeover by ...
The weight savings from deleting a bearing and associated parts listed below gave an engine with a thrust of 5,000 lbf but weighing only 800 lb. [2] [i] Eliminating the usual centre support bearing for the shaft joining the compressor and turbine meant the shaft would whirl, assuming a bowed shape, and damage the engine. Whirling was prevented ...

Rolls-Royce is the world's second-largest maker of aircraft engines [3] (after CFM International) [4] and has major businesses in the marine propulsion and energy sectors. Rolls-Royce was the world's 16th largest defence contractor in 2018 when measured by defence revenues. [5]
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 ...
