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 four Rolls-Royce RB162 lift engines seen from the bottom of a nacelle. The design of the Do 31 was heavily reliant upon its engine configuration. Dornier had opted to incorporate the British-built Bristol Pegasus [note 1] vectored-thrust turbofan engine, an existing powerplant that was most famously used to power the Harrier jump jet.

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.

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 ...
To meet the heavier weight of the aircraft, Rolls-Royce was expected to design a Pegasus engine variant that would have produced 4,000 lbf (18 kN) more thrust than the latest production variant at the time. The Harrier III would have carried weapons such as AIM-120 AMRAAM and AIM-132 ASRAAM missiles.
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.
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.
