Patent ID: 6910328

Claim:
A vectorable variable area nozzle comprising: a pair of fixed parallel sidewalls; a pair of opposing elements which extend between the sidewalls and are mounted for rotation about a common first axis orthogonal to the sidewalls; a first actuator means for moving a first of the elements about the first axis, and a second actuator means for moving a second of the elements about the first axis, to define a convergent nozzle section; a pair of opposing flaps extending between the sidewalls downstream of the opposing elements, each of said flaps being mounted for rotation relative to an adjacent one of the elements at the downstream end of said adjacent element, a first of said flaps being mounted for rotation about a second axis orthogonal to the sidewalls and a second of said flaps being mounted for rotation about a third axis orthogonal to the sidewalls, the respective axis of rotation of each flap being situated between upstream and downstream ends of the flap; a third actuator means for moving the first of the flaps about the second axis, and a fourth actuator means for moving the second of the flaps about the third axis, to define a divergent nozzle section.
