A nonaxisymmetric, variable area, exhaust nozzle is provided with thrust vectoring capabilities in one plane. The nozzle incorporates an upper, thrust vectoring flap to control direction of thrust over various flight conditions, and a lower, area control flap that is pivoted to modify size and location of the nozzle throat. The structural aspects of this nozzle provide a unique capability to vector thrust up to 60 degrees while changing the nozzle throat position to a region downstream of the vectoring of the exhaust gases.

Vectorable nozzle

A propulsion nozzle having a substantially axial nozzle shroud and an articulated plug mounted in spacial relation therewith to form a motive fluid flow path having a throat therebetween. The plug is articulative to permit the throat of the nozzle to be disposed, as required, in a position at the downstream end of the shroud or at a position upstream of the downstream end without translating either the shroud or the plug.
