Turbofan engine assembly operating method for aircraft, involves selectively positioning portion of core cowl baffle between operational positions with respect to another core cowl baffle to vary throat area of fan nozzle duct

摘要

The method involves varying an operating speed of a fan assembly (16) from an operating speed to another operating speed. A portion of a core cowl baffle (101) is selectively positioned between the operational positions with respect to another core cowl baffle (102) to vary a throat area of the fan nozzle duct. The latter core cowl baffle is positioned flush against a portion of the core cowl (22). Independent claims are also included for the following: (1) an inner core cowl baffle assembly for a turbofan engine assembly (2) a turbofan engine assembly.
