ACOUSTIC PANEL WITH SIDEWALL STRINGERS
A panel for attenuating noise includes a porous first skin, a second skin, and a core (26) connected between the porous first skin and the second skin. The core (26) includes a corrugated body (42) and a stringer body (44). The corrugated body (42) includes a plurality of corrugations (48) configured from at least a plurality of baffles (52) and a plurality of porous septums (53). Each of the corrugations (48) includes a respective one of the baffles (52) and a respective one of the porous septums (53). A first of the corrugations (48) forms a first channel (76) that extends laterally between and longitudinally along a first of the baffles (52) and a first of the porous septums (53). The stringer body (44) includes a plurality of sidewalls (80) arranged longitudinally along the first channel (76). Each of the sidewalls (80) is disposed within the first channel (76) and configured to fluidly isolate longitudinally adjacent portions of the first channel (76) from one another.
