Title (EN) ACOUSTIC DEVICE, AND GAS TURBINE
(FR) DISPOSITIF ACOUSTIQUE ET TURBINE À GAZ
(JA) 音響装置、ガスタービン
Abstract:
(EN) This acoustic device (4) is provided with: a porous plate (32) having, on one plate-thickness-direction side, a plurality of holes (34) which pass through in the plate thickness direction and through which a main current flows; and a housing (33) which is provided to the other plate-thickness-direction side of the porous plate (32) and which is sectioned off from the porous plate (32) by a space, at least a part of each of the holes (34) on one plate-thickness-direction side being inclined toward either one side or the other side in the direction in which the main current flows.
(FR) La présente invention concerne un dispositif acoustique (4) qui est pourvu de : une plaque poreuse (32) comportant, sur un côté de direction d’épaisseur de plaque, une pluralité de trous (34) qui traversent dans la direction de l’épaisseur de la plaque et à travers lesquels un courant principal circule ; et un boîtier (33) qui est disposé sur l’autre côté de direction d’épaisseur de plaque de la plaque poreuse (32) et qui est séparé de la plaque poreuse (32) par un espace, au moins une partie de chacun des trous (34) sur un côté de direction d’épaisseur de plaque étant inclinés vers un côté ou l’autre côté dans la direction dans laquelle le courant principal circule.
(JA) 音響装置(4)は、板厚方向の一方側に主流が流通し、板厚方向に貫通する複数の孔部(34)を有する多孔板(32)と、多孔板(32)の板厚方向他方側に設けられて、多孔板(32)との間に空間を区画するハウジング(33)とを備え、孔部(34)における少なくとも板厚方向一方側の部分が、主流の流通方向の一方側及び他方側の少なくともいずれかに傾斜している。
