Abstract

L'invention concerne un ensemble propulsif d'aéronef, comportant : - un générateur de gaz comportant une soufflante entourée par un carter (30), et - une nacelle (32) s'étendant autour dudit carter et définissant avec ce carter un compartiment (36) annulaire dans lequel sont logés des équipements, - des moyens d'entrée d'air (38) agencés pour qu'un débit d'air de ventilation pénètre dans ledit compartiment, et - des moyens de sortie d'air (44) agencés pour qu'un débit d'air de ventilation soit évacué dudit compartiment, caractérisé en ce qu'il comporte également : - des moyens de réglage de débit (40) configurés pour maintenir une valeur nominale du débit d'air de ventilation traversant au moins l'un desdits moyens d'entrée d'air et desdits moyens de sortie d'air en fonctionnement nominal, et pour réduire la valeur de ce débit d'air de ventilation lorsqu'un feu est détecté dans ledit compartiment.
