Abstract
A gas turbine has a compressor for compressing air as a working fluid, a combustor for producing combustion gas by mixing fuel with the compressed air, and a turbine for generating a rotating force at the time of expansion of combustion gas. The gas turbine further includes a cylindrical liner; a transition piece for transferring the working fluid from the liner to the turbine; an outlet portion of the transition piece, which has a region parallel with a direction of a rotating shaft of the turbine; cooling holes formed in the region so that longitudinal intervals thereof are lengthened; and a picture frame portion provided to secure stiffness at an outlet of the outlet portion.
