VARIABLE AREA NOZZLE ASSEMBLY AND METHOD FOR OPERATING SAME
DRIVE
October 23, 2024
A variable area nozzle assembly (50) for a gas turbine engine (20) includes a fixed structure (52) including a first fixed ring (64) and a second fixed ring (66). The second fixed ring (66) is spaced axially aft from the first fixed ring (64) to define a first portion of an ejector passage (68) therebetween. A nozzle (58) defines an inner radial exhaust flow path surface (74). The nozzle (58) includes a forward ejector door (86) and an aft ejector door (88). The forward ejector door (86) and the aft ejector door (88) define a first surface portion of the inner radial exhaust flow path surface (74). Each of the forward ejector door (86) and the aft ejector door (88) are pivotable between respective closed positions and respective open positions. A translating ejector sleeve (108) is mounted within the fixed structure (52) and configured to axially translate within the fixed structure (52) between a first axial position and a second axial position.
