摘要: 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).
