A nozzle includes a sideways split and aftwardly swept nozzle ramp extends between a fixed lower nozzle wall and a pivotal upper nozzle wall pivotally connected to an aft end of the nozzle and operable to vary a throat area of a throat of the nozzle. The upper and lower nozzle walls and the ramp extend transversely between first and second nozzle sidewalls. A sideways pivotable ramp structure pivotally connected to the lower nozzle wall and pivotable between the sidewalls includes a longitudinally extending upper pivotable wall spaced upwardly and aftwardly of a longitudinally extending lower pivotable wall and an aftwardly swept pivotable ramp extending between the upper and lower pivotable walls. Right hand and left hand upper ramp sections of the nozzle ramp may be connected to right hand and left hand upper nozzle wall sections respectively of the upper nozzle wall which are pivotally connected to right and left handed triangular side walls of the aft end.
