FAN NACELLE, NACELLE ASSEMBLY AND METHOD FOR CHANGING ANNULAR FAN OUTLET AREA

摘要

PROBLEM TO BE SOLVED: To provide an effective variable area nozzle for a gas turbine engine fan nacelle for relatively reducing cost. SOLUTION: The variable area nozzle FVAN 28 for a fan adjusts a flap assembly 44 via a link mechanism 46, by rotating a synchronous ring 46 to a stationary ring 42, for changing the annular fan outlet area of releasing fan air. Engine thrust and fuel saving are maximized in respective flying states by adjusting the FVAN 28. COPYRIGHT: (C)2008,JPO&INPIT
