1. An exhaust nozzle assembly for use with a propulsion system for an aircraft, the propulsion system including an engine configured to produce a jet, the exhaust nozzle assembly comprising:
a nozzle body configured to be fluidly coupled with the engine and to receive the jet;
an outer cover at least partially covering the nozzle body;
a movable component configured to move between a first position and a second position when a force is applied to the movable component, the movable component disposed and configured to have an effect on one of the jet and an exhaust plume produced by the propulsion system when the movable component moves between the first position and the second position; and
a linkage coupled to the movable component and adapted for coupling to an actuator configured to generate the force, the linkage transmitting the force to the moveable component when the linkage is coupled with the actuator and when the actuator is actuated,
wherein a gap exists between an inner surface of the outer cover and an outer surface of the nozzle body,
wherein the linkage is partially disposed within the gap,
wherein the exhaust nozzle assembly is free of the actuator, and
wherein a cross-sectional dimension of the linkage is smaller than a smallest dimension of the actuator, and wherein a dimension of the gap is smaller than the smallest dimension of the actuator and greater than the cross-sectional dimension of the linkage.
