Nacelle for an aircraft engine with inlet flow control system and corresponding operation method

摘要

An inlet flow control system disposed within a nacelle (12) includes a panel (26) on an inner surface (26) of that nacelle (12). The panel (26) includes a noise attenuation layer (30) that dissipates noise energy. A vacuum source generates a pressure differential across the noise attenuation layer (30) for drawing airflow through the panel (26) and away from an inner surface (16) of the nacelle (12).
