Beschreibung
Zusammenfassung:	The invention relates to an exhaust casing for a turbine engine of an aircraft, including: a collar (4), a hub (5), hollow arms (63) connecting said collar (4) to said hub (5), and an opening piece (3) which is located on the collar (4) and is suitable for being connected to an outlet tube (30) of a transient-operation valve of the turbine engine. In said exhaust casing, said opening piece (3) is attached onto the collar (4) and forms an extension of a hollow arm (63) such that an air flow (7) leaving the outlet tube (30) of the transient-operation valve penetrates the hollow arm (63) and flows into the hub (5). L'invention concerne un carter d'échappement pour une turbomachine d'un aéronef comprenant une virole (4), un moyeu (5), des bras creux (63) reliant ladite virole (4) audit moyeu (5), et une bouche (3) située sur la virole (4) et qui est adaptée pour être connectée à un tube de sortie (30) d'une vanne de régime transitoire de la turbomachine, où ladite bouche (3) est fixée sur la virole (4) dans le prolongement d'un bras creux (63), de manière qu'un flux d'air (7) sortant du tube de sortie (30) de la vanne de régime transitoire pénètre dans le bras creux (63) et circule à l'intérieur du moyeu (5).
