发明名称 TRANSLATING VARIABLE AREA FAN NOZZLE PROVIDING AN UPSTREAM BYPASS FLOW EXIT
摘要 A variable area fan nozzle assembly for a turbofan engine includes a nacelle having an aft edge and a translating nozzle segment having a forward edge and a first end. The nozzle segment is movably disposed behind the aft edge such that an upstream bypass flow exit is defined between the aft edge and the forward edge when the nozzle segment is in a deployed position. A deflector is disposed between the aft edge and the forward edge proximate to the first end. The deflector substantially prevents bypass flow from exiting the upstream bypass flow exit in a region that is proximate to the first end.

主权项 1. A variable area fan nozzle assembly for a turbofan engine, the assembly comprising: (a) a nacelle having an aft edge; (b) a translating nozzle segment having a forward edge and a first end, the nozzle segment being movably disposed behind the aft edge, wherein an upstream bypass flow exit is defined between the aft edge and the forward edge when the nozzle segment is in a deployed position; (c) a deflector disposed between the aft edge and the forward edge proximate to the first end, wherein the deflector substantially prevents bypass flow from exiting the upstream bypass flow exit in a region that is proximate to the first end, wherein at least a portion of the deflector is received in a void in one of the nozzle segment and the nacelle, when the nozzle segment is in the stowed position.
