Rolls-Royce Bristol Pegasus, engine of the vertical takeoff Harrier, in the Bristol Industrial Museum, England. Pegasus 1 (BE53-2) The two prototype engines were demonstrator engines which developed about 9,000 lbf (40 kN) on the test bed. Neither engine was installed in a P.1127. Pegasus 2 (BE53-3) Used in the initial P.1127s, 11,500 lbf (51 kN)

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.
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.

An RAF Harrier GR.7A at RIAT 2005 The GR.7A is a GR.7 with an uprated Rolls-Royce Pegasus 107 engine. The Mk 107 engine provides around 3,000 lbf (13 kN) extra thrust than the Mk 105's 21,750 lbf (98 kN) thrust, increasing aircraft performance during "hot and high" and carrier-borne operations.

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.
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 ...
