ONE-STAGE STATOR VANE COOLING STRUCTURE AND GAS TURBINE

摘要

Provided is a one-stage stator vane cooling structure that is equipped with multiple linking members that are provided between multiple combustors disposed in the circumferential direction of a gas turbine, and cooling holes that are provided in each of the one-stage stator vanes to discharge a cooling gas from the inside to the outside of the one-stage stator vanes in order to cool the one-stage stator vanes on the periphery of the stagnation line of the combustion gas inflowing from the multiple combustors. The cooling holes are formed at positions that are determined according to the relative positions between the one-stage stator vanes and the linking members disposed near the one-stage stator vanes.
