TURBOFAN ENGINE COWL ASSEMBLY AND METHOD OF OPERATING THE SAME

摘要

An inner core cowl baffle assembly (100) for a turbofan engine assembly (10) including a core gas turbine engine (20), a core cowl (22) which circumscribes the core gas turbine engine, a nacelle (24) positioned radially outward from the core cowl, and a fan nozzle duct (26) defined between the core cowl and the nacelle. The inner core cowl baffle assembly includes a first core cowl baffle (101) coupled to a portion (19) of the core cowl within the fan nozzle duct, a second core cowl baffle (102) coupled to a portion (21) of the core cowl and positioned a distance radially inward from the first core cowl baffle, and an actuator assembly (110) configured to vary the throat area of the fan nozzle duct by selectively repositioning the second core cowl baffle with respect to the first core cowl baffle.
