Abstract

Accurate prediction of its thermal and structural response characteristics, when a hypersonic vehicle flies at high speed, is a very important issue in its design and manufacturing. Complex thermal and structural behavior is produced in the structure due to the interaction of aerodynamic force and aerodynamic heating applied to the vehicle, which in turn changes the flow field around the vehicle. In this study, as a Two-way fluid-thermal-structure coupling method, an ANSYS and CFX coupling method by ANSYS's MFX Multi-field Solver was established and applied to the study of thermal and structural response of hypersonic vehicles. In order to verify the validity of the coupling method proposed in this study, a comparison with NASA Langley's cylindrical leading-edge model test results is conducted. By analyzing the calculation results of the flow field, temperature field, and structure field of the cylindrical leading-edge model, it was concluded that this coupling method is effective with high accuracy. The numerical calculation results can provide accurate technical support for the thermal protection design and structural design of hypersonic vehicles.
