Abstract (en)
[origin: WO2008104716A2] The invention relates to a method for making an acoustic treatment coating particularly applied at a leading edge, such as the air intake of an aircraft nacelle, said acoustic treatment coating including a reflective layer, a cellular structure (30) and an acoustically-resistive structure, characterised in that it comprises: digitising the shape that the cellular structure (30) will assume once it is applied on the surface to be treated; virtually positioning, in order to define their geometries, two series of strips (38, 40) in order to define a duct between two adjacent strips (38) of the first series on the one hand, and two adjacent strips (40) of the second series on the other hand; cutting each of the strips (38, 40) according to their previously defined geometries; forming in each of the strips (38, 40) cut-outs for assembling said strips (38, 40); assembling said strips (38, 40) in order to obtain a cellular structure having shapes conforming to the surface to be treated.
