    摘要: Flow evacuation system for an aircraft engine comprising an engine nozzle (31) that conveys the engine exhaust flow (11) and an eductor (33) receiving said engine exhaust flow (11) and the engine ventilation flow (13), the engine nozzle (31) having a final section (32) in contact by its outer surface with said ventilation flow (13), the engine exhaust flow (11) having a low swirl when the engine operates under design conditions and a high swirl when the engine operates out of design conditions, the engine nozzle (31) comprising a plurality of local flow conditioners (41) placed in its inner surface in said final section (32) for reducing the swirl of the engine exhaust flow (11) at the exit of the engine nozzle (31).
