Variable area fan nozzle thrust reverser

摘要

A nozzle for use in a gas turbine engine includes nozzle doors coupled with a fan nacelle wherein the nozzle doors move in unison between a plurality of positions to influence a bypass airflow through a fan bypass passage. A linkage connects the nozzle doors and an actuator. A louver section coupled with the linkage moves in unison with the nozzle doors between a plurality of louver positions to direct a portion of the bypass airflow in a selected direction.

主权项

1. A method of controlling a gas turbine engine system disposed about a centerline axis and having a fan bypass passage for conveying a bypass airflow, comprising the steps of:
moving a first nozzle door, a second nozzle door that is located radially inwards of the first nozzle door relative to the centerline axis, and a louver section in unison between a plurality of positions to influence the bypass airflow through the fan bypass passage; moving each of the nozzle doors about a pivot point; and moving the first nozzle door in an aft direction about its pivot point in unison with moving the second nozzle door in a forward direction about its pivot point.
