Summary:An afterburner nozzle actuation system includes a case, an actuation structure, a plurality of cam plates, a plurality of nozzle flaps and seals, and a plurality of rollers. The actuation structure surrounds at least a portion of the case and includes an aft end that has a polygonal cross section shape. The cam plates are removably coupled to an inner surface of the actuation structure, and each includes a cam surface. The nozzle flaps are rotationally coupled to the case and extend at least partially from the actuation structure aft end. Each nozzle flap is movably coupled to a different one of the cam plates. The rollers are each rotationally mounted on a different one of the nozzle flaps and engage the cam surface of one of the cam plates.
