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.

The system was an evident improvement over mechanical control but had its drawbacks, including common electronic noise interference and reliability issues. Full authority analogue control was used in the 1960s and introduced as a component of the Rolls-Royce/Snecma Olympus 593 engine of the supersonic transport aircraft Concorde. [3]
the rear of the F135 engine (nozzle rotated down) that powers the Rolls-Royce LiftSystem. Instead of using separate lift engines, like the Yakovlev Yak-38, or rotating nozzles for engine bypass air, like the Harrier, the "LiftSystem" has a shaft-driven LiftFan, designed by Lockheed Martin and developed by Rolls-Royce, [3] and a thrust vectoring nozzle for the engine exhaust that provides lift ...
The purchase was completed on 10 December 2012 and Aero Engine Controls became wholly owned by Rolls-Royce Plc and a part of the Rolls-Royce Group. in 2014 Rolls-Royce announced the merger of two wholly owned subsidiaries, Aero Engine Controls (AEC) and Optimized Systems and Solutions (OSyS), to form a new business, Controls and Data Services ...
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 ...
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 equivalent vanes on the Rolls-Royce Nene reduced the inlet losses to the extent that thrust was increased from 4,000 to 5,000 lb at the same turbine temperature. [ 103 ] Modern subsonic inlet with rounded inlet lip to prevent boundary layer separation in cross winds on the ground and high angle of attack during take-off rotation.
