The invention concerns a ventilating air intake arrangement with mobile sealing device. The arrangement comprises at least one air passage channel (12) with an air vent (14), and is designed to ventilate at least one confined zone (11) in an aircraft with fresh air entering upstream, through the air vent, in the channel and exiting downstream thereof towards the zone to be ventilated. The invention is characterized in that the cross-section of the air passage channel (12) is automatically adjustable based on the speed and the altitude of the aircraft and the arrangement comprises therefor controllable mobile-element closing means (17) associated with the channel and for varying its cross-section.
Agencement d'entrée d'air de ventilation à élément d'obturation mobile. L'agencement comporte au moins un canal (12) de passage d'air avec un orifice (14) de prise d'air, et est destiné à ventiler au moins une zone confinée (11) dans un aéronef par de l'air extérieur entrant en amont, par l'orifice de prise d'air, dans le canal et sortant en aval de celui-ci en direction de la zone à ventiler. Selon l'invention, la section transversale du canal (12) de passage d'air est réglable automatiquement en fonction de la vitesse et de l'altitude de l'aéronef et l'agencement comporte pour cela des moyens d'obturation à élément mobile commandable (17) associés au canal et permettant de faire varier sa section transversale.
