PROBLEM TO BE SOLVED: To suppress combustion vibration of a combustor throughout by a wide range of frequency bands. SOLUTION: A resonance box having a resonance pipe bent like a labyrinth is attached to the combustor. Porous metals are attached to two or more portions of the resonance pipe. The resonance box having the labyrinth like resonance pipe is small, and it resonates with vibration of a low frequency. By the porous metals attached to two or more portions, vibration throughout a wide range of frequency bands is damped. COPYRIGHT: (C)2006,JPO&NCIPI
