Patent ID: 8398016

Claim:
An air intake arrangement for an aircraft, comprising: at least one air passage channel provided with an air intake hole receiving an external air flow, plugging means with controllable mobile plate associated with the at least one air passage channel, and means for controlling the controllable mobile plate allowing variation of the cross-section of the at least one air passage channel between a minimum cross-section enabling a minimum air flow rate toward an area to be ventilated of the aircraft and a maximum cross-section enabling a maximum air flow rate toward the area, the plate comprising an external side subjected to the air flow and an internal side directed toward the at least one air passage channel, the upstream end of the plate being connected to the at least one air passage channel, in the vicinity of the upstream edge of the air intake hole, and the downstream end of the plate being free to move through the cross-section of the at least one air passage channel, wherein when the aircraft is in a cruising flight, the downstream edge of the air intake hole is able to generate a high pressure on a limited downstream area of the external side; and wherein the controlling means comprise fluid communication means between the external and internal sides of the mobile plate, located at least in the vicinity of the limited downstream area of the external side and able to communicate the high pressure to an extended area of the internal side.
