摘　　要：热防护技术是决定高超声速飞行器设计成败的关键要素。高超声速飞行器不同部位将承受不同的力、热载荷,需选择不同的热防护方案。以HTV-2、X-37B和NASA的亚轨道运输飞行器为例,系统介绍三类典型高超声速飞行器采用的热防护方案,并揭示了热防护技术的最新进展。未来,材料工艺技术的发展和创新型热防护方案的研发,将进一步提升热防护系统的技术成熟度和适用范围,为各类高超声速飞行器的设计研制提供重要的能力保障。Thermal protection technology is the key factor to the design of hypersonic vehicle. The different parts of hypersonic vehicle undertake different kinds of force and thermal loads,so different thermal protection projects are required. The paper takes HTV- 2,X- 37 B and NASA suborbital transportation vehicle as examples,introduces three kinds of thermal protection projects and discloses the latest developments of thermal protection technology. In future,the development of material technology and innovative thermal protection program can improve the technology maturity and the scope of application of thermal protection system and provide a guarantee for the design of each kind of hypersonic vehicle.
