An acoustic liner is made by placing a raw adhesive septum between a pair of opposite honeycomb cores, and curing the septum to integrally bond the cores thereto.
Claims29
A method of making an acoustic liner comprising:
- placing a raw adhesive septum in abutting contact between a pair of opposite honeycomb cores aligned and sized to effect Helmholtz resonators for attenuating noise;
- and
- curing said septum to integrally bond said cores thereto.
A method of making an acoustic liner comprising:
- placing a raw, perforate adhesive septum in abutting contact between a pair of opposite honeycomb cores;
- curing said septum to integrally bond said cores thereto without plugging perforations in said septum;
- and
- sandwiching said pair of cores between a porous face sheet and an impervious back sheet.
