Abstract
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).
Claims15
An exhaust casing for an aircraft turbine engine comprising a shroud, a hub forming a cavity, at least one hollow arms connecting said shroud to said hub, and at least one mouth situated on the shroud and which is suitable to be connected to an outlet tube of a transient-operation valve of the turbine engine, said at least one mouth is attached to the shroud in the extension of the at least one hollow arm, so that an air flow exiting the outlet tube of the transient-operation valve penetrates into the at least one hollow arm and circulates in the cavity of the hub, wherein the exhaust casing comprises at least one yoke arm connecting said shroud to said hub, wherein the at least one yoke arm is solid and comprises a first stiffener, the first stiffener being situated in the hub, and that the at least one hollow arm adjoins said at least one yoke arm and comprises a deflector so as to deflect the air flow exiting said at least one hollow arm toward the first stiffener of the at least one yoke arm.
