高超音速飞行器气动热研究进展

高超音速飞行器具有普通超音速飞行器无法比拟的优势，因而成为航空航天领域重要的发展方向。当飞行器高速飞行时，空气粘性作用将在机体上产生强烈的气动热，这给飞行器的安全造成严重影响，成为制约高超音速飞行器快速发展的瓶颈问题；无疑，掌握气动热变化规律是合理设计高超音速飞行器热防护的基础。本文从实验与数值仿真两方面系统地归纳、总结国内外学者在高超音速飞行器气动热方面的研究成果，并展望其未来的发展。

Research Advan ces of Aerodynamic Heating for Hypersonic Aircraft

Due to the unparallel advantage of the hypersonic vehicles compared with the common su-personic ones, it becomes the important development direction in the area of the aeronautics and astronau-tics.However , this technology is dramatically restricted by the violent aerodynamic heating which is caused by the ultra-high speed viscous flow of air through the aircraft surfaces and will affect the security of aircrafts.Obviously, it is the key technology for the design of hypersonic aircrafts to comprehend the change rules of the aerodynamic heating.The current research results and prospective on the aerodynamic heating for hypersonic aircrafts are summarized including experiments and numerical simulations.
