Abstract

The paper describes the method of obtaining the equation for spatial-temporal dependence of the heat transfer intensity of model samples under standardized thermo-fatigue damage studies of gas turbine blades in gas flow of variable parameters. Methods of the theory of the similarity of thermal processes underlie in the equation’s structure. The described numerical analysis uses results of complex bench tests of models under different regimes of non-stationary gas overflow. The obtained equation in criteria form allows describing conditions of samples’ heat exchange under thermal loading on the gas-dynamic test bench under a wide range of sizes and regimes.
