ABSTRACT:
A gas jet engine nozzle such as a turbine engine nozzle is provided for directing an axial flow in a downstream direction of exhaust gases to obtain thrust vectoring. The gas jet engine nozzle comprises an exhaust nozzle member for channeling the axial flow of the exhaust gases into a flow field, and a plug movably positioned substantially within the exhaust nozzle member and in the flow field for interacting with the gases to control the direction of flow of the gases. The plug has a substantially continuous surface including a diverging forebody portion and a monotonically converging afterbody portion. The afterbody portion is in the downstream direction relative to the forebody portion. A support structure is coupled to the plug for movably supporting the plug within the exhaust nozzle member and in the flow field. A hydraulic actuating system is operatively coupled to the plug for selectively controlling the position of the plug.
