A lightweight multifunction exhaust nozzle is designed with a specially contoured short length transition casing and a correspondingly contoured pair of convergent flaps. The change in flowpath section from circular to rectangular takes place partly within the transition casing and partly between the pair of convergent flaps such that the transition section of the exhaust nozzle is integrated with its convergent section. The convergent flaps are pivotally mounted in the exhaust nozzle so that exhaust gasses impacting the convergent flaps produce counteracting moments about a convergent flap shaft pivot axis thereby reducing the load on the convergent flap actuators.
