PROCÉDÉ DE RÉALISATION D'UNE STRUCTURE D'ABSORPTION ACOUSTIQUE COMPRENANT UNE PEAU FORMANT UNE PLURALITÉ D'ENCEINTES, STRUCTURE D'ABSORPTION ACOUSTIQUE OBTENUE SELON LEDIT PROCÉDÉ ET AÉRONEF COMPRENANT LADITE STRUCTURE D'ABSORPTION ACOUSTIQUE
A method for producing an acoustic absorption structure comprising an acoustically resistive structure, an alveolar structure, a reflective layer and a plurality of acoustic elements positioned in the alveolar structure, against the acoustically resistive structure, the method comprising forming a skin forming enclosures of the acoustic elements by depositing a resin on a mold having a base on which are positioned projecting forms shaped like the cavities delimited by the enclosures of the acoustic elements, placing the mold supporting the resin together with the alveolar structure, the resin being intercalated between the mold and the alveolar structure, polymerizing the resin to simultaneously obtain a hardening of the skin and also the joint between the skin and the alveolar structure, and fitting the acoustically resistive structure and the reflective layer.
