1. A method for articulating an exhaust nozzle to vary at least one of a nozzle throat area and a nozzle exit area, the method comprising:
moving a first nozzle actuator to vary an angle of an outer articulating panel of the exhaust nozzle with respect to a forward bulkhead and to at least one of maintain or vary the nozzle exit area;
moving a second nozzle actuator to vary an angle of an inner articulating panel of the exhaust nozzle with respect to the forward bulkhead;
varying an angle between a forward inner skin of the inner articulating panel and an aft inner skin of the inner articulating panel in response to performing the step of moving the second nozzle actuator to at least one of maintain or vary the nozzle throat area;
moving a first thrust reverser actuator to pivot an outer thrust reverser door between a stowed position and a deployed position, wherein the outer thrust reverser door is pivotally mounted to an outer skin of the outer articulating panel; and
moving a second thrust reverser actuator to pivot an inner thrust reverser door between a stowed position and a deployed position, wherein the inner thrust reverser door is pivotally mounted to the aft inner skin of the inner articulating panel.
