VARIABLE AREA NOZZLE FOR GAS TURBINE ENGINE

摘要

A variable area fan nozzle (100) comprises an actuator flap (114) and a follower flap (106). The actuator flap (114) has a portion in contact with a portion of the follower flap (106). A bias member (112) biases the follower flap (114) outwardly. An actuator (120) actuates the actuator flap (114) inwardly and outwardly to, in turn, move the follower flap (106) against the bias member (112) and to vary an area of an exhaust nozzle. The flap actuator (120) is operable to drive the actuator flap (114) out of contact with the follower flap (106) into a thrust reverser position.
