ABSTRACT:
Positionable deflector means are provided in a gas turbine engine inlet duct. The deflector means are actuated to change the axial and circumferential location of a forward protruding extension of the inlet duct in order to selectively reduce noise propagation. A method is disclosed for directional noise shielding as a gas turbine engine experiences altitude and operational changes.
