COMBINED INLET LAMINAR AND THRUST REVERSER CASCADE EFFLUX FLOW CONTROL SYSTEM

摘要

A nacelle assembly (16) for a gas turbine engine includes a fan nacelle (62) bounding a bypass flow path (B). The fan nacelle (62) includes a first nacelle section (68A) and a second nacelle section (68B). The second nacelle section (68B) includes a moveable portion (79) movable relative to a forward portion (81) to define a secondary flow passage (74). The first nacelle section (68A) includes an inlet lip (71). A thrust reverser (72) is configured to selectively communicate a portion of bypass airflow between the bypass flow path (B) and the secondary flow passage (74). A pump (88) is configured to selectively communicate airflow between the inlet lip (71) and the secondary flow passage (74).
