<p>A damping device (63) is provided in a bypass pipe (61) for supplying high-pressure air to a combustor tail pipe. The damping device (63) has a fluid introduction portion (71) covering the outer periphery of the bypath pipe (61) to form a fluid introduction space (B), acoustic boxes (73a, 73b) having base ends connected to the fluid introduction portion (71) and also having head ends circumferentially extending on the outer periphery of the bypass pipe (61) to form resonance spaces (Da, Db), and partition plates (74a, 74b) forming resonance ducts (Ea, Eb), having a predetermined length, by partitioning the resonance spaces (Da, Db).</p> |
