MOVABLE AIR OUTLET DEVICE FOR AN AIRCRAFT

摘要

The subject of the invention is an air outlet device fitted with a grid (10) fitted to an aerodynamic surface of an aircraft, wherein said grid comprises a plurality of openings defined by intermediate zones extending away from the aerodynamic surface of the aircraft, said device and the grid are characterized by an area known as the flow area through which air can flow, characterized in that it comprises at least one movable portion in order to increase the flow area of said device, particularly in the event of failure, and in that the grid (10) has a flow area determined according to the flow rate of air to be discharged in the most extreme normal flight conditions, in the absence of a failure.
