Title (EN) METHOD FOR MANUFACTURING A CELLULAR CORE FOR AN ACOUSTIC PANEL
(FR) PROCEDE DE FABRICATION D'UNE AME ALVEOLAIRE POUR PANNEAU ACOUSTIQUE
Abstract:
(EN) The invention relates to a method for manufacturing a cellular core (34) for an acoustic panel (30), the cellular core (34) comprising at least one plurality of acoustic cells (36) and a plurality of de-icing channels (48) that extend longitudinally, each de-icing channel (48) being transversely interposed between two successive cells (36), the de-icing channels (48) being adapted to channel a de-icing fluid, characterised in that it comprises a manufacturing step that involves producing the acoustic cells (36) and the de-icing channels (48) as a single piece, the cellular core (34) thus manufactured during the manufacturing step forming a monolithic part.
(FR) L'invention concerne un procédé de fabrication d'une âme alvéolaire (34) pour panneau acoustique (30), l'âme alvéolaire (34) comportant au moins une pluralité de cellules (36) acoustiques et une pluralité de canaux (48) de dégivrage qui s'étendent longitudinalement, chaque canal (48) de dégivrage étant interposé transversalement entre deux cellules (36) successives,les canaux (48) de dégivrage étant adaptés pour canaliser un fluide de dégivrage, caractérisé en ce qu'il comporte une étape de fabrication qui consiste à réaliser les cellules (36) acoustiques et les canaux (48) de dégivrage venus de matière, l'âme alvéolaire (34) ainsi fabriquée au cours de l'étape de fabrication formant une pièce monolithique.
