ABSTRACT:
An air inlet for an aircraft engine is disclosed. The inlet includes a nacelle and a fairing spaced therefrom for defining an inlet duct to the engine. The fairing includes a plurality of inlet apertures in flow communication with ambient air and the nacelle includes at least one outlet aperture which is also in flow communication with ambient air. A plurality of struts extends between the fairing and the nacelle and a plurality of flow channels is provided therein, each extending in flow communication from respective ones of said inlet apertures through said struts and nacelle and to said outlet aperture. During operation, the air inlet receives air, and a portion thereof adjacent to the fairing is channeled through the inlet apertures and flow channels out the outlet aperture into the ambient air flowing over the nacelle to bleed off relatively low pressure recovery air.
