The invention concerns an arrangement comprising at least one air passage channel (12) with an air vent (14), and 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 adjustable based on the speed and the altitude of the aircraft and the arrangement comprises therefor a membrane (19) elastically deformable under the action of a fluid control (18) to enable said channel cross-section to be varied.
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 en fonction de la vitesse et de l'altitude de l'aéronef et l'agencement comporte pour cela une membrane (19) élastiquement déformable sous l'action d'une commande fluidique (18) pour permettre de faire varier la section transversale dudit canal.
