  • Patent number: 11022304
    Abstract: A combustor is provided with a combustion liner (12) in which a combustion gas flows through the inner peripheral side and a plurality of through-holes (14) are formed, and a sound attenuator (20) having a space-forming member (21) configured to form a space (S) connected to the plurality of through-holes (14) at the outer peripheral side of the combustion liner (12). The space-forming member has a main body having an opening configured to bring an outside and the space in communication with each other, and a lid joined to an outer surface of the main body via a welded portion and configured to protrude outward and close the opening.
    Type: Grant
