Patent ID: 8584363

Claim:
A method for making an acoustic panel of an air intake lip of a nacelle comprising: A. producing an outer skin reproducing an aerodynamic line of the air intake lip; B. fastening a conductive layer on said outer skin, said conductive layer including conducting members; C. fastening a photosensitive layer on said conductive layer, said photosensitive layer including at least one photosensitive member; D. piercing the material thus formed using a piercing means to form acoustic holes; E. applying a mask on the photosensitive layer of material at the end of step D so as to form an array of conducting members not obstructing the holes resulting from step D; F. revealing said array using a photolithography method; G. electrically isolating the surface of the array resulting from step F; H. fastening a cellular core structure on the de-icing assembly obtained at the end of step G; I. applying a second skin on the de-icing assembly thus obtained at the end of step H, thereby forming an acoustic panel.
