Abstract

Ensemble propulsif (2) comportant un générateur de gaz muni d’une soufflante entouré par un carter externe (3) annulaire, ledit générateur et ledit carter (3) définissant entre eux une veine d’écoulement d’un flux d’air, ledit ensemble (2) comprenant un dispositif de refroidissement d’air destiné à l’aéronef (1) comportant un échangeur de chaleur (6) traversé par un circuit primaire ainsi qu’un circuit secondaire dont l’entrée est reliée à des moyens de prélèvement d’air (10) dudit flux d’air et la sortie est reliée à des moyens d’évacuation de l’air prélevé (11) à l’extérieur, caractérisé en ce que ledit dispositif de refroidissement d’air destiné à l’aéronef (1) est configuré pour permettre le passage d’air via le circuit secondaire depuis lesdits moyens de prélèvement (10) jusqu’aux moyens d’évacuation (11) de manière à décharger ladite veine lors d’une surpression du flux d’air dans ladite veine en aval de ladite soufflante suivant le sens d’écoulement dudit flux d’air.
