Abstract:

The HarrierAV-8 aircraft, with its Rolls-Royce Pegasus engine, was developed primarily for vertical or short takeoff and landing operations. To achieve this it employs nozzles capable of vectoring through more than 90 deg to provide lift and a reaction control system to provide aircraft have also been employed to achieve a tactical advantage during combat by vectoring in forward flight VIFFING. Operational analysis studies have identified the potential combat advantage of post-stall manoeuvring PSM to improve rate of turn and vehicleweapon pointing. To achieve any or all of these capabilities ie VSTOL, VIFF and PSM will require some degree of propulsion system thrust vectoring. Some particular requirements that the need for thrust vectoring place on the engine design and the technologies involved are addressed in this paper.
