Abstract

L'invention concerne un ensemble pour turbomachine comprenant une partie aval de turbine (10) et un carter d'échappement (40) situé en aval de la partie aval de turbine (10), la partie aval de turbine (10) comprenant un carter de turbine (30). Le carter d'échappement (40) comprend une virole externe (400) et au moins une chape de fixation (48) du carter d'échappement (40) à un mât d'accrochage de turbomachine. Selon l'invention, une portion amont (410) de la virole externe (400) loge au moins une partie d'un dernier étage de turbine (10) de la partie aval de turbine (10).
