Claims11
A defrosting and acoustic treatment device for an air intake lip of a turbojet engine nacelle comprising an embossed acoustic structure adapted to bear on an acoustic skin of the air intake lip, and delimiting a plurality of acoustic cells, each acoustic cell being delimited by an independent peripheral wall allowing circulation of a defrost air flow around each acoustic cell.
A method for manufacturing a defrosting and acoustic treatment device for an air intake lip of a turbojet engine nacelle, wherein the defrosting and acoustic treatment device comprises an embossed acoustic structure delimiting a plurality of acoustic cells, each acoustic cell being delimited by an independent peripheral wall allowing circulation of a defrost air flow around each acoustic cell, wherein the method comprises at least one manufacturing process producing the embossed acoustic structure made in one piece into a monolithic part.
