초록

A nacelle structure for a gas turbine engine includes an inlet aft of an exit guide vane for supplying air flow to a forward plenum. Air is exhausted from the plenum into an air intake opening and over an inner surface of the nacelle for controlling air flow characteristics within the nacelle.

청구항

What is claimed is: 1. An inlet flow control system for a nacelle comprising: an air intake opening; an inlet disposed in an aft portion of the nacelle for drawing in airflow; a plenum disposed adjacent said air intake opening for receiving air flow from said inlet; and an outlet disposed on an outer surface of the nacelle for communicating air flow from said plenum along the outside of the nacelle and into said air intake opening of the nacelle for tailoring airflow within said nacelle to current operating conditions. 2. The system as recited in cla...
