HIGH-TEMPERATURE COMPONENT OF GAS TURBINE, GAS TURBINE EQUIPPED WITH SAME, AND METHOD FOR MANUFACTURING HIGH-TEMPERATURE COMPONENT OF GAS TURBINE

摘要

This high-temperature component (450) of a gas turbine is equipped with a plate-like member that has a gas path surface (451) facing the inner side and/or the outer side of a combustion gas flow path in the radial direction of a rotor. A cooling flow path is formed in the plate-like member internally along the outer periphery (452), which intersects the gas path surface (451). The plate-like member has an outer periphery-side turbulator (482) that protrudes from an outer periphery (452) side of the inner surface of the cooling flow path.
