Since the conditions in which the hollow static blade of the turbine is located are very harsh, mainly surrounded by high-temperature combustion gas with a large temperature difference, the guide core is installed in the hollow cavity of the hollow static blade of the turbine. Its function is to guide the flow direction of the compressed air in the hollow static blade of the turbine when the hollow static blade of the turbine is working, increase the residence time of the compressed air in the hollow static blade of the turbine to cool the hollow static blade of the turbine and prevent the burning of the hollow static blade of the turbine. Therefore, when the guide core performs cooling work in the hollow static blade of the turbine, it needs to meet the gas flow test requirements to achieve the cooling effect, so there are strict requirements on the external dimensions and profile deviation of the guide core.
