PROBLEM TO BE SOLVED: To provide an air intake duct which suppresses solid propagation of a specific frequency to be discharged outside caused by vibration of a wall of an air intake duct body.SOLUTION: An air intake duct includes an air intake duct body 41 and a resonator 50. The air intake duct body 41 is an air flow passage Ain on an air intake side of a gas turbine. The resonator 50 includes an opening 43 which is opened in the air intake duct body 41, and a resonance chamber 53 communicating with the air flow passage Ain via the opening 43. The resonator 50 is then resonated with respect to a specific frequency component. |
