Abstract

A bypass valve assembly for a gas turbine engine includes a frame defining a first flow channel in flow communication, second and third flow channels separated by a splitter. A plurality of circumferentially juxtaposed bypass doors are disposed in the second channel and are positionable between a closed position preventing airflow into the second channel and an open position providing for airflow into the second channel. Means for automatically positioning the doors in the open and closed positions provides differential pressure across the doors in the second channel, and include a spring which provides a closing torque on the door.
