Abstract

The invention relates to an arrangement (1) that comprises a mobile plate (18) controlled by a means for fluid communication (23) between the outer (18A) and inner surfaces of the mobile plate (18), wherein said means is located at least in the vicinity of a limited downstream area (24) of said outer surface (18A), are at a high pressure when the aircraft flies at cruising speed, and are capable of transmitting said high pressure to an extended area (26) of said inner surface.

Description

technical field [0001] The invention relates to an air intake device for an aircraft, comprising a ventilation channel with an air intake opening. Background technique [0002] It is known that such air intake devices are used extensively in the aviation sector for renewing the air in enclosed areas containing hazardous ambient media of the flammable or explosive type and / or heat-sensitive materials, It is necessary for them to ensure continuous ventilation of the area in order to avoid any risk of failure of the material or of accidents in the vicinity. [0003] This is especially the case for the plurality of mechanical and / or electrical devices arranged in the annular enclosure between the outer casings of the compressors and blowers of the aircraft turbojet and the nacelle. Said devices, such as the Full Authority Digital Engine Control (Full Authority Digital Engine Control in English), the auxiliary relay box (Gearbox in English), the engine oil container, the fluid p...
