ABSTRACT:
A turbofan engine includes a fan variable area nozzle having a multiple of vents through a fan nacelle and rotatable elements rotatable within the vents by an actuator system. Rotation of the rotatable element within each vent changes the effective area of the fan nozzle exit area to permit efficient operation at a multiple of flight conditions.
