Abstract
An acoustic liner 20 includes a remote panel 26, a proximate panel 28 transversely spaced from the remote panel and a resonator chamber 34b residing between the panels. Perforations 38 penetrate the proximate panel in registration with the resonator chamber 34b. A neck 56 with an inlet 58 recessed from the proximate panel establishes communication between the chamber and a fluid stream G flowing past the proximate panel. A bypass coolant passage 66 guides coolant through the perforations without guiding it through the resonator chamber.
