ACOUSTIC PANEL WITH SIDEWALL STRINGERS
A panel is provided for attenuating noise. This panel includes a porous first skin, a second skin and a core (26), which is connected between the porous first skin and the second skin. The core (26) includes a corrugated body (42) and a plurality of stringer bodies (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 (54). Each of the corrugations (48) includes a respective one of the baffles (52) and a respective one of the porous septums (54). A first of the corrugations (48) forms a first channel (78) that extends laterally between a first of the baffles (52) and a first of the porous septums (54). The stringer bodies (44) are spaced longitudinally along the first channel (78). Each of the stringer bodies (44) includes a first sidewall (82) disposed within the first channel (78) and configured to fluidly isolate longitudinally adjacent portions of the first channel (78) from one another.
