A variable area nozzle assembly (54) for a gas turbine engine (20) includes a nozzle (60) disposed about a nozzle centerline (146) and a fixed ring (82) radially surrounding the nozzle (60). The nozzle (60) includes a radially outer surface (64) and a radi...

A variable area fan nozzle comprising an array of rigid petals and a petal actuation system comprising left and right assemblies, each assembly comprising: a multiplicity of tracks attached to or integrally formed with respective petals; a curved pivoting ...

A variable area fan nozzle comprising an array of hinged rigid petals and a petal actuation system in which the principle of actuation is realized by changes in shape (i.e., deformation) of the actuators rather than by movement of cooperating mechanical pa...

Methods and apparatus for sealing variable area fan nozzles (214) of jet engines (200) are disclosed. An apparatus in accordance with the teachings of this disclosure includes a frame and a seal (218) to be coupled to the frame. The seal to enclose petals ...

A fan case (72) of a gas turbine engine (20) includes a fan blade containment section (78) defined about an engine axis (A), a thrust reverser cascade section (80) downstream of the blade containment section (78) and a Fan Exit Guide Vane section (82) down...

The nozzle has a control system for controlling movable flaps (12a, 12b, 13). The system has control levers composed of controlled levers (16a) directly actuated by jacks (18) and follower levers (16b) actuated by the levers (16a) through a transmission li...

A gas turbine engine (10) includes a variable area nozzle (30) having a plurality of flaps (38). The flaps (38) are actuated by a plurality of actuating mechanisms (40) driven by shape memory alloy (SMA) actuators (68) to vary fan exist nozzle area (36). T...
