Considering the problem that the comprehensive cooling efficiency test of turbine blades is carried out under stationary conditions and the difference with the real rotation conditions of the engine leads to the failure of reflecting accurately the cooling performance of the blades under real working conditions, a modeling method suitable for the comprehensive cooling efficiency test results of turbine blades was proposed. Through theoretical derivation and sensitivity analysis, the influence laws of multiple factors such as rotation on the comprehensive cooling efficiency of turbine blades were obtained. The flow ratio had the greatest impact on the comprehensive cooling efficiency, the mainstream Reynolds number and the equivalent speed were the second, and the temperature ratio had the lowest impact. Compared with the traditional molding method without considering the influence of rotation, the molding method improved the prediction accuracy of the comprehensive cooling efficiency of the turbine blade by more than 50%, and the final average error was 3%, and the maximum error was 6%.
