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.
Harrier GR3 XW920 Engine flame out over Sardinia due to fuel supply failure, Flight Lieutenant James Downey ejected safely. [18] [23] 27 June 1972 No. 4 Squadron RAF: Harrier GR1 XV780 Crashed after engine fire near RAF Gutersloh, West Germany due to bird strike; Wing Commander McKee ejected safely.

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. [1] GR.9
Both versions of Harrier experienced reduced engine performance (Pegasus Mk 106 in FA2 and Mk 105 in GR7) in the higher ambient temperatures of the Middle East, which restricted the weight of payload that the Harrier could return to the carrier in 'vertical' recoveries. [20] This was due to the safety factors associated with aircraft landing ...
The Harrier, informally referred to as the Harrier jump jet, is a family of jet-powered attack aircraft capable of vertical/short takeoff and landing operations (V/STOL). Named after a bird of prey, [1] it was originally developed by British manufacturer Hawker Siddeley in the 1960s. The Harrier emerged as the only truly successful V/STOL ...
On her voyage home, Hawker Siddeley demonstrated a RAF Harrier GR.Mk.1 (XV757) but Argentina opted for the A-4Q Skyhawk instead. There were several problems to supply Argentina with Harrier jets and engines that prevented the deal from being closed, and when the US learned of the Harrier negotiations they quickly offered a better deal to Argentina.
The Mk 107 engine provides around 3,000 lbf (13 kN) extra thrust over the Mk 105's 21,750 lbf (98 kN) thrust. GR.9 The GR9 is an upgrade of the GR7, focused on the Harrier II's avionics and weapons.
In 1984 they assembled in a test rig at Shoeburyness a Harrier airframe created from the damaged remains of T.Mk.2 XW264 and GR.Mk.1 XV798 to assist in their investigations in the effects of PCB. [1] The project was extant from 1980 to 1988 and showed promise with only some hot gas recirculation issues having been identified. [3]
