The patent application relates to a deformable plug for use within an aircraft engine exhaust nozzle system. It has thrust vectoring and thrust reversing capability, as well as the capability to vary the nozzle area thereby improving propulsion efficiency. This invention uses an exhaust nozzle passageway having a rectangular nozzle exit area with the aerodynamically shaped plug centrally located in the path of the engine exhaust gases. The portion of the plug extending aft to the nozzle exit plane comprises of a pair of oppositely facing flaps that can be actuated to provide thrust vector and thrust reversal control as desired. The portion of the plug extending forward of the nozzle exit plane provides for variable throat area control.
