An inlet flow control system disposed within a nacelle includes a panel on an inner surface of that nacelle. The panel includes a noise attenuation layer that dissipates noise energy. A vacuum source generates a pressure differential across the noise attenuation layer for drawing airflow through the panel and away from an inner surface of the nacelle.
1. A method for preventing separation of air flow from an inner surface of a nacelle for a gas turbine engine comprising the steps of: communicating air along the inner surface of the nacelle with a noise attenuation structure, wherein the noise attenuation structure comprises a face sheet including a plurality of openings communicating with a plurality of cells with uninterrupted solid walls, and a back sheet supporting the plurality of cells and including a plurality of openings in communication with the plurality of cells;generating a pressure differe...
