Abstract

TURBOMACHINE AXIALE TRIPLE-FLUX AVEC ÉCHANGEUR DE CHALEUR L’invention a trait à une turbomachine, comprenant : un premier bec de séparation apte à séparer un flux d’air entrant en un flux d’air radialement interne et un flux d’air secondaire ; un deuxième bec de séparation apte à séparer le flux d’air radialement interne en un flux primaire et un flux tertiaire parcourant une veine de flux tertiaire radialement externe à une veine de flux primaire parcourue par le flux primaire ; un échangeur de chaleur (18) disposé dans la veine de flux tertiaire ; et un carter interne (28) ;remarquable en ce que l’échangeur comprend un corps (32) et une bride (32.1) s’étendant radialement intérieurement et en saillie du corps, la bride étant fixée au carter interne, l’échangeur comprenant en outre, en aval de la bride, une partie aval (40) à laquelle est rapportée une paroi feu (46) formant un bouclier thermique.
