    • An exhaust induced ejector nozzle (20) includes a convergent portion (30) and a divergent portion (34) disposed downstream from the convergent portion (30). The ejector nozzle (20) also includes an ejector (40) having an outlet (46) disposed within the divergent portion (34). The ejector (40) is operable to provide entrainment of a nacelle airflow (18) from a nacelle airflow area (44) into the divergent portion (34). The ejector nozzle (20) further includes a convergent ejector (60) extending between the convergent portion (30) and the nacelle airflow area (44). The convergent ejector (60) is operable to draw a portion of an exhaust airflow (42) into the nacelle airflow area (44) to increase a flow rate of the nacelle airflow (18).
    • 排气感应喷射器喷嘴(20)包括会聚部分(30)和设置在会聚部分(30)下游的发散部分(34)。 喷射器喷嘴(20)还包括具有设置在发散部分(34)内的出口(46)的喷射器(40)。 喷射器(40)可操作以将机舱气流(18)从机舱气流区域(44)引入到发散部分(34)中。 喷射器喷嘴(20)还包括在收敛部分(30)和机舱气流区域(44)之间延伸的会聚喷射器(60)。 会聚喷射器(60)可操作以将一部分排气气流(42)吸入机舱气流区域(44)中以增加机舱气流(18)的流量。
