An air distribution system for an impeller mar cavity (30), including an air bleed (46) at the compressor impeller (22) tip for bleeding pressurized air into the rear cavity, and a second stream of P3 air is passed into the rear cavity area (30) after having been cooled by a heat exchanger (36). The mixing of the cooled P3 air (46) with the bleed air from the impeller tip reduces the temperature of the pressurized air in the rear cavity to reduce degradation of the impeller as well as to provide a flow of cooling air for the central bearing.

L'invention concerne un système de distribution d'air destiné à une cavité arrière (30) d'hélice, comprenant un prélèvement d'air (46) au niveau du bout de l'hélice (22) du compresseur, servant à décharger de l'air sous pression dans une cavité arrière, un second jet d'air P3 (air haute pression) étant dirigé dans la zone de la cavité arrière (30), après avoir été refroidi par un échangeur de chaleur (36). Le mélange de l'air P3 refroidi (46) et de l'air prélevé à partir du bout de l'hélice diminue la température de l'air sous pression dans la cavité arrière, de manière à réduire la dégradation de l'hélice et en même temps à constituer un écoulement d'air de refroidissement destiné au direction du palier central.
