Abstract
A turbofan engine including an exhaust casing traversed by a primary flow and surrounded by a secondary flow and an outlet cone carried by this exhaust casing, the exhaust casing and the outlet cone together defining an internal space. The exhaust casing includes a hollow radial arm traversing the primary flow in order to convey part of the secondary flow so as to form a cooling flow for supplying the internal space, and the outlet cone is terminated by an opening for discharging the cooling flow.

1-7. (canceled)
A turbofan engine including an exhaust casing (21) through which passes a primary flow (FP) and surrounded by a secondary flow (FS) both circulating from upstream (AM) to downstream (AV) of the turbofan engine during operation, and an outlet cone (23) having an upstream end (25) carried by this exhaust casing (21), the outlet cone (23) delimiting an inner space (E), wherein the exhaust casing (21) includes a hollow radial arm (38) crossing the primary flow (FP) which conveys part of the secondary flow (FS) in order to form a cooling flow (Fr) to cool down one or several component(s) located in the inner space (E), and in that the outlet cone (23) terminates in an opening (S) for discharging the cooling flow (Fr).
