高超声速飞行器内流道燃料超声速气膜防热/减阻协同技术研究进展

Supersonic film thermal protection/drag reduction cooperative technology is considered to be an important method for realizing thermal protection and drag reduction simultaneously for internal flow of hypersonic vehicles. The current paper first analyzes the demands and challenges of thermal protection and drag reduction for the internal flow of hypersonic vehicles， and on this basis introduces thermal protection technology for internal flow of hypersonic vehicles， drag reduction technology for internal flow of hypersonic vehicles， and the proposing and basic principle for fuel supersonic film thermal protection/drag reduction cooperative technology respectively. Furthermore， the investigations related to fuel supersonic film thermal protection/drag reduction cooperative technology are summarized and reviewed. The related investigations had confirmed the feasibility and revealed the mechanism of the thermal protection and drag reduction coordination for fuel supersonic film. However， few present studies focused on fuel supersonic film thermal protection/drag reduction cooperative technology had been conducted， the technology worth further study and research. Finally， the current paper proposes several suggestions for the future investigation.
