Abstract

L'objet principal de l'invention est un système (1) de circulation d'air de refroidissement (A1-A4) d'aubes (24a) de turbine (24) d'une turbomachine (10), caractérisé en ce qu'il comporte un conduit amont (2) de circulation d'air de refroidissement (A1) pour le prélèvement d'air de refroidissement (A1) depuis un compresseur (22) de la turbomachine (10), un conduit aval (3) de circulation d'air de refroidissement (A3) pour l'acheminement d'air de refroidissement (A4) vers les aubes (24a) de turbine (24), et un échangeur thermique (4) positionné entre le conduit amont (2) et le conduit aval (3) pour refroidir l'air de refroidissement (A1) prélevé depuis le compresseur (22) avant son acheminement vers les aubes (24a) de turbine (24) par l'intermédiaire du conduit aval (3).
