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 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 ...
Combined with thrust from the LiftFan (20,000 lbf or 89.0 kN) and two roll posts (1,950 lbf or 8.67 kN each), the Rolls-Royce LiftSystem produced a total of 41,900 lbf (186 kN) of thrust. [35] This compares with the maximum thrust of 23,800 lbf (106 kN) for the Harrier's Rolls-Royce Pegasus engine.
A full authority digital engine (or electronics) control (FADEC) is a system consisting of a digital computer, called an "electronic engine controller" (EEC) or "engine control unit" (ECU), and its related accessories that control all aspects of aircraft engine performance.
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 ...
Rolls-Royce Pegasus The Bristol Siddeley Orpheus is a single-spool turbojet developed by Bristol Siddeley for various light fighter /trainer applications such as the Folland Gnat and the Fiat G.91 .
Despite Rolls-Royce hitting back hard on forecast growth and scoring a narrow-margin point for operating margin, BAE takes the round by three points to two. Round 2: dividends Rolls-Royce
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 ...
