LARGE LIFTING FORCE SYSTEM FOR AIRCRAFT WITH MAIN WING AND RE-INSTALLABLE SLIP

摘要

1. A system for providing a large lift for an aircraft with a main wing and a slat that is repositioned in relation to it by means of a repositioning device in different repositionable states, between the rear side (1b) of which facing the main wing and the main wing (2) a slot (5) is formed, the size of which follows from the resettable state of the slat (1) relative to the main wing (2),! characterized in that! an air duct (11) with at least one air duct inlet (20) and one air duct outlet is formed inside the slat,! the inlet (20) of the air duct is located on the rear side (1b) facing the main wing, so that air flows from the slot (5) through the inlet (20) of the air duct into the air duct (11). ! 2. The high lift system according to claim 1, characterized in that the mass flow at the inlet (20) of the air duct on the rear side (1b) facing the main wing can be adjusted by a flow controller in order to influence the flow in the slot (5 ). ! 3. The high lift system according to claim 1, characterized in that the flow regulator has a locking device that can be opened and closed based on the pressure acting on the rear side (1b). ! 4. The system for providing high lift according to claim 2, characterized in that the flow regulator has an opening part located at the inlet (20) of the air duct and displaced to the closed position of the inlet (20) of the air duct, which is adjusted in such a way that the opening part when predefined, emerging
