Abstract
La présente invention concerne un carter (1) d’échappement d’une turbomachine comprenant : - un moyeu (2) centré sur un axe (XX’) du carter (1) ; - une virole (3) s’étendant autour du moyeu (2) ; - une pluralité de bras (4) qui s’étendent du moyeu (2) à la virole (3), chaque bras (4) comprenant une paroi interne (41) délimitant un logement (40) s’étendant entre le moyeu (2) et la virole (3) ; et - au moins une nervure (5) fixée sur la paroi interne (41) d’au moins un bras (4), ladite nervure (5) s’étendant en saillie de la paroi interne (41) du bras (4) entre le moyeu (2) et la virole (3), l’au moins une nervure (5) s’étendant jusqu’au moyeu (2) de sorte à former un pont thermique. Figure pour l’abrégé : Fig. 1The present invention relates to an exhaust casing (1) of a turbomachine comprising: - a hub (2) centered on an axis (XX') of the casing (1); - a ferrule (3) extending around the hub (2); - a plurality of arms (4) which extend from the hub (2) to the ferrule (3), each arm (4) comprising an internal wall (41) delimiting a housing (40) extending between the hub (2 ) and the ferrule (3); and - at least one rib (5) fixed to the internal wall (41) of at least one arm (4), said rib (5) extending projecting from the internal wall (41) of the arm (4) between the hub (2) and the ferrule (3), the at least one rib (5) extending to the hub (2) so as to form a thermal bridge. Figure for abstract: Fig. 1
