An exhaust nozzle for a gas turbine engine including a plurality of primary and secondary flaps which are pivotally positionable for varying the geometry of the nozzle and for providing thrust vectoring. Electromechanical actuators preferably are used to position the flaps. The inner surfaces of the primary flaps are preferably curved convexly to continually maintain the location of the nozzle throat on the primary flaps. Reverser doors can be added to permit thrust reversal and fairing flaps can be included outwardly of the primary and secondary flaps to maintain a smooth, aerodynamic flow.

An exhaust nozzle for a gas turbine engine comprising: (a) a fixed structure; (b) a plurality of primary flaps each having a portion pivotally connected with said fixed structure and having an inner surface curved convexly in a downstream direction; (c) a plurality of secondary flaps disposed downstream of said primary flaps, each of said secondary flaps having a portion pivotally connected with a downstream end of one of said primary flaps in a cantilever arrangement therewith; and (d) means for pivotally positioning said primary and said secondary flaps; each of said primary flaps and each of said secondary flaps being pivotably positionable independently of any other primary or secondary flap.
