The invention claimed is: 1. A mechanism included in a convergent-divergent nozzle configured to be connected to an aftward portion of a gas turbine engine, the mechanism comprising:at least one actuator configured to be connected to the aftward portion of the engine and to move a first coupling point through one or more positions;an annular ring connected to the at least one actuator, providing to the at least one actuator a second coupling point to move through the one or more positions, the second coupling point being disposed radially outward from the first coupling point and a main axis of the engine;a first link pivotally connected directly to the first coupling point of the at least one actuator;a convergent flap pivotally connected to the first link;a divergent flap rotatably connected to the convergent flap and configured to be kinematically connected to the second coupling point; andat least one track configured to extend from the aftward portion of the engine and which movably and pivotally receives the connection between the convergent flap and the first link.
