Acoustic panel with folding chamber
A panel is provided for attenuating noise. This panel includes a perforated first skin, a second skin, an array of corrugations, a first channel, a second channel, a plurality of first sidewalls and a plurality of second sidewalls. The array of corrugations includes a first corrugation and a second corrugation. Each of the corrugations includes a baffle and a septum. The first channel is formed by the baffle of the first corrugation, the septum of the first corrugation and the first skin. The second channel is formed by the baffle of the second corrugation, the septum of the first corrugation and the second skin. The first sidewalls divide the first channel into a plurality of first chambers. The second sidewalls divide the second channel into a plurality of second chambers. A first of the second chambers is fluidly coupled with a subset of the first chambers through perforations in the septum of the first corrugation.
