ABSTRACT:
An inboard wing trailing edge flap of an aircraft has a flap carriage mechanism located within the fuselage or a fuselage/wing fairing structure, and the flap is attached to the carriage by a torque tube which penetrates the side of the fuselage. A slot is required in the fuselage through which the torque tube can travel as the flap is extended and retracted. The slot is covered when the flap is fully retracted, but when the flap is fully extended, airflow through the slot toward the upper surface of the flap causes the flap to lose lift. Therefore, airflow blocker doors are provided for closure of the slot when the flap is fully extended. The doors are held in a closed position by a pressure differential across the slot and by spring-loaded hinges; and the doors are adapted to be opened by engagement of a ramp cam member mounted to the flap torque tube, as the flap is retracted.
