Abstract
Structure utilisant les avantages inhérents du matériau sandwich en nid d'abeilles sans le soumettre à des niveaux élevés de contraintes thermiques. La structure comporte une paroi de conduit 18 dans laquelle un panneau acoustique basse fréquence 38 est encastré en retrait de façon à former une poche dans laquelle coulisse un panneau acoustique haute fréquence du type sandwich en nid d'abeilles 26 au moyen de joints glissants 54, le panneau basse fréquence étant également du type sandwich comportant une série de cellules munies de tubes saillants 42 qui traversent avec jeu des ouvertures 52 formées dans le panneau haute fréquence pour déboucher dans le conduit où le bruit est engendré. Application à l'insonorisation des tuyères des moteurs à turbines à gaz.
