Turbomachine with collection of a compressed air flow

A turbine engine comprising:

• an exhaust casing, comprising a plurality of arms, the space separating the arms defining openings in which a primary airflow of the turbine engine circulates, said exhaust casino further comprising an internal hub and an external shroud between which the arms extend:
• at least one duct,
• configured to collect at one of its ends a compressed airflow,
• the other end of the duct being connected to at least one opening of the exhaust casing, so as to insert the collected airflow into said primary airflow, said collected airflow haying, during its insertion in the opening, a Mach number less than or equal to 0.5,
• the duct terminating at its other end in a plurality of secondary ducts, the secondary ducts being connected to the openings of the exhaust casing, to insert the collected airflow into said exhaust casing, the end of the secondary ducts passing through the outer shroud of the exhaust casing to pour into the openings the collected airflow, each secondary duct being connected to a different opening of the exhaust casing, to send the collected airflow to the exhaust casing.
