Aerodynamic heating and structural heat transfer coupling issues are very important in the aerospace field. It points out the necessity of coupling in the process of experiment and analysis. Aiming at the existing coupling, the method of combining the structural thermal test with the calculation of the aerodynamic heating is presented. The full-scale heat flux density control method is proposed to simulate the whole trajectory, and the experimental control of the aerodynamic analysis coupled with the thermal test is realized. It provides a solution to aerodynamic heating and structural thermal response coupling analysis of aircraft fuel system. At the same time, a new method is proposed for the thermal load condition of structural thermal test. The aerodynamic analysis and structural heat of aircraft with complex thermal structure Test is of great significance. The numerical simulation results are compared with the experimental results, the two agree well.
