Abstract: Thermal contact resistance must be accurately evaluated to ensure proper design and safety of hypersonic vehicles. In terms of the C/SiC composite material for hypersonic vehicle structures, an approach for assessing the thermal contact resistance of this material is proposed and wind tunnel experiments are performed. The change law of the thermal contact resistance for the C/SiC composite material is also investigated. The results show that the thermal contact resistance and contact resistance proposed in this paper have good accuracy compared with the wind tunnel results, with a difference of only 4%. The proposed approach and test results serve as a reference for designing and evaluating the structure and thermal protection performance of hypersonic vehicles.
