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.

A gas jet engine nozzle for directing an axial flow in a downstream direction along an axis of exhaust gases to obtain thrust vectoring, the engine nozzle comprising: an exhaust nozzle member for channeling the axial flow of the exhaust gases into a flow field; flow directing means 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 flow directing means having a substantially continuous surface including a diverging forebody portion and a converging afterbody portion, the afterbody portion being in the downstream direction relative to the forebody portion and including a segment having a substantially conical shape, the flow directing means being pivotally movable so that the afterbody portion moves to nonaxial positions in two dimensions perpendicular to each other and perpendicular to the axis; support means coupled to the flow directing means for movably supporting the flow directing means within the exhaust nozzle member and in the flow field; and actuating means operatively coupled to the flow directing means for selectively controlling the position of the flow directing means.
