초록

A noise suppression system for a jet engine, the system having a substrate formed of open cell material, a layer of microporous material covering at least a portion of one surface of the substrate, a layer of substantially non-porous material covering at least one portion of an opposite surface of the substrate, and a pressurized air source for providing pressurized air to the substrate. The substrate, the microporous material, and the non-porous material are configured to define an inner surface of an inlet for the jet engine. The pressurized air is com...
