    • A system is provided in an aircraft that includes a power unit and an eductor. The power unit has a nozzle, and is configured to exhaust gas, a portion of which flows in a swirling motion, through the nozzle. The eductor communicates with the power unit and includes a housing and a plurality of flow straighteners. The housing has an inlet, an outlet, and an inner peripheral surface that defines a flow passage. The inlet is configured to surround at least a portion of the nozzle and to receive the gas, and the outlet is configured to exhaust the gas. The plurality of flow straighteners extend radially inwardly from the housing inner surface into the flow passage and are configured to reduce swirl motion of the gas that flows therethrough. The power unit may be an auxiliary power unit or a turboshaft engine.
    • 在包括动力单元和喷射器的飞行器中提供系统。 动力单元具有喷嘴,并被构造成通过喷嘴排出其一部分以旋转运动流动的气体。 喷射器与动力单元连通并且包括壳体和多个流动矫直机。 壳体具有入口,出口和限定流动通道的内周表面。 入口构造成围绕喷嘴的至少一部分并且接收气体,并且出口构造成排出气体。 多个流动矫直机从壳体内表面径向向内延伸到流动通道中并且构造成减少流过其中的气体的旋转运动。 动力单元可以是辅助动力单元或涡轮轴发动机。
