Abstract

La présente invention se rapporte à un carter d'échappement (100) pour turbomachine comprenant un moyeu (4), une virole extérieure (6), des bras de raccord (24), ainsi qu'au moins une ferrure de passage d'efforts (20) destinée à l'accrochage du carter sur un élément extérieur (22). Selon l'invention, l'un des bras (24) comprend au moins un organe structural (28) s'étendant dans une direction donnée entre le moyeu et la ferrure (20), cet organe (28) traversant la virole (6) d'une manière autorisant localement un déplacement relatif, au moins selon la direction donnée, entre d'une part l'ensemble solidaire formé par l'organe structural (28) et la ferrure (20), et d' autre part la virole extérieure (6).
