Abstract

Une nacelle (500) peut comprendre une structure de suppression de bruit (100). La structure de suppression de bruit (100) peut comprendre une pluralité de cellules de suppression de bruit (102a, 102b, 102c) placée entre une couche perforée de matériau (202) et une couche non-perforée de matériau (204). La pluralité de cellules de suppression de bruit (102a, 102b, 102c) peut entrer en contact avec la couche perforée de matériau (202) et la couche non-perforée de matériau (204) à un angle aigu (par exemple, entre 20° et 75°) de sorte que la pluralité de cellules de suppression de bruit (102a, 102b, 102c) est en position non-orthogonale par rapport à la couche perforée de matériau (202) et la couche non-perforée de matériau (204). En outre, chacune de la pluralité de cellules de suppression de bruit (102a, 102b, 102c) peut avoir un profil hexagonal en coupe. En outre, la structure de suppression de bruit (100) peut comprendre une structure de support comprenant une pluralité d'éléments de support (402a, 402b, 402c, 402d), la pluralité de cellules de suppression de bruit (102a, 102b, 102c) étant située dans la structure de support.
