In order to meet the need of thermal-vibration joint test of high-speed cruise missile heat-resistant components, a high-temperature thermal-vibration test environment simulation system for high-speed aircraft is established. The system consists of a vibration excitation test system and a thermal environment simulation test system. The continuous change of the surface temperature of the projectile during the high-speed flight of a missile performs a dynamic reappearance of the simulation process of the aerodynamic heating, and the vibration excitation system applies a vibration excitation to the heat-proof component. The experimental results show that the environmental test system can provide a high- State of safe flight to provide a reliable basis.
