ABSTRACT:
An actuation assembly for selectively varying the throat area of a convergent-divergent exhaust nozzle of a gas turbine engine and simultaneously achieving predetermined fixed ratios of throat area versus exit area. The assembly structurally comprises a plurality of constituent components (including a linear actuator member on the port side, and another on the starboard side, of the nozzle in parallel spaced-apart relationship with the centerline common to the engine and to the exhaust nozzle) that interact and cooperate to pivot the convergent flaps to reduce the throat area while simultaneously moving the divergent flaps inwardly, or to pivot the convergent flaps to increase the throat area while simultaneously moving the divergent flaps outwardly, as desired, thereby permitting the selective varying of the throat area while attaining a predetermined fixed ratio of the throat area to the exit area of the convergent-divergent exhaust nozzle. In addition, and unlike the prior art, the respective lengths of linear movements required to effectuate either the convergent flaps from a minimum throat area position to a maximum throat area position or the divergent flaps from a minimum exit area position to a maximum exit area position are equal, as are the respective lengths in the converse. Thusly, only a single actuator per side is required.
