Abstract

L’invention concerne un carter (2) d’échappement pour une turbomachine (1) d’axe (X) longitudinal comprenant : une virole externe (3) centrée sur l’axe (X) ;un moyeu (4) présentant une surface radialement extérieure (49) centrée sur l’axe (X) qui délimite une veine (A) de circulation des gaz radialement vers l’intérieur ;une pluralité de bras radiaux (6) solidarisant ladite virole externe (3) audit moyeu (4), caractérisé en ce que ledit carter d’échappement (2) comprend en outre un circuit d’alimentation en air comprenant au moins une entrée d’air (50) débouchant sur cette surface radialement extérieure (49) et une sortie d’air (51) qui débouche sur cette surface radialement extérieure (49) et qui se situe en aval de ladite entrée d’air (50), de sorte à prélever de l’air provenant de ladite veine (A) et à la faire traverser au moins partiellement ladite surface radialement extérieure (49), ladite au moins une entrée d’air (50) et ladite au moins une sorte d’air (51) étant reliées par un premier réseau (52) de canaux thermiques.
