Device for discharging oil ventilation air from lubrication oil venting system of dual flow jet engine, has air outlet formed at suction side and at pressure side such that oil ventilation air is exhausted over air outlet into flow channel

摘要

The device has a low pressure turbine (70) provided with multiple turbine stages, which comprise stator wheels (71, 73) and stator disks (72, 74). Each stator disk comprises a set of guide vanes arranged in a flow channel (3) of the turbine, where each guide vane comprises a suction side and a pressure side. Each guide vane comprises a cavity (145) into which oil ventilation air is introduced before exhaust. An air outlet (150) is formed at the suction side and/or at the pressure side such that the oil ventilation air is exhausted over the air outlet into the flow channel.
