- Hypersonic vehicles operating under wide flight-envelope conditions, high heat flux, and long-duration service are subjected to extremely complex thermal environments. Consequently, thermal protection and thermal management of hypersonic engines have become one of the key bottlenecks restricting the development of advanced propulsion systems. With the rapid advancement of air-breathing hypersonic engines, combined-cycle propulsion systems, and reusable flight vehicles, traditional passive thermal protection methods can no longer satisfy the integrated demands of high heat-flux resistance, severe temperature-rise mitigation, and lightweight design. Therefore, there is an urgent need to develop novel thermal management technologies featuring efficient heat dissipation, structural load-bearing capability, and integrated energy utilization. This forum focuses on the fundamental theories, key technologies, and engineering applications of thermal protection and thermal management for hypersonic engines. Discussions will mainly cover regenerative cooling, fuel heat-sink utilization, active cooling, advanced thermal-structural design, heat transfer mechanisms under extreme conditions, multi-physics coupled numerical simulation, intelligent optimization design, and advanced experimental diagnostics and testing techniques. The forum aims to explore future development trends and critical challenges in thermal management technologies for hypersonic propulsion systems, thereby promoting academic innovation and engineering applications in related fields.
