FLAP ASSEMBLY FOR EXHAUST NOZZLE DEVICE, AIRCRAFT ENGINE NOZZLE ASSEMBLY, AND METHOD FOR ADJUSTING SIZE OF EXHAUST OUTLET AREA OF AIRCRAFT ENGINE NOZZLE ASSEMBLY

摘要

PROBLEM TO BE SOLVED: To provide an exhaust nozzle assembly capable of allowing increase of a scope of flap moving while suppressing friction junction to the minimum extent. SOLUTION: This aircraft engine nozzle assembly includes an adjustable flap 24 that is movable about a pivot for changing the size of an exhaust exit area. A bracket 36 having a curved slot 64 establishes a range of possible movement of the flap part 34. A link 40 includes a guide member 72 that is received in the curved slot 64 for guiding the movement of the flap part 34. The link 40 is connected to a static engine structure and the bracket 36 is movable with the flap part 34. The curved slot 64 establishes a range of possible movement of the flap part 34 along the direction of the curved slot. COPYRIGHT: (C)2007,JPO&INPIT
