A method for forming an acoustic panel assembly for an aircraft propulsion system is provided that includes: forming a plurality of cell rows of an acoustic core by, for each cell row of the plurality of cell rows, cutting and folding a sheet to form each cell row with a plurality of cells, and each cell includes a first transverse panel, first and second longitudinal panels and an oblique panel, and the first and second longitudinal panels extend transversely from the first transverse panel; positioning the cell rows on an inner skin extending circumferentially about an axial centerline; attaching the longitudinal panels of a cell to the oblique panel of that cell, and attaching each cell row of the plurality of cell rows to at least one other cell row to form the acoustic core.
