Abstract
A variable area nozzle system for a gas turbine engine is provided which includes actuating means for opening and closing of the nozzle. The actuating means are adapted to operatively engage a convergent flap for rotating the flap in a first direction of rotation to close the nozzle. The actuating means are further adapted to engage a compression link for rotating the link in a second direction of rotation to open the nozzle.
Claims4
A variable area nozzle system for a gas turbine engine comprising in combination:
- a convergent flap pivotally connected to said engine;
- a divergent flap pivotally connected to said convergent flap;
- a rotatable compression link pivotally connected to said engine and to said divergent flap;
- an outer flap pivotally attached at its upstream end to said engine and at its downstream end to said divergent flap;
- and
- an actuator adapted to selectively modulate said variable area nozzle between a fully closed position and a fully open position, said actuator adapted to operatively engage said convergent flap for rotating said convergent flap in a first direction of rotation, said actuator further adapted to operatively engage said compression link for rotating said compression link in a second direction of rotation.
