摘要:
随着航天技术的发展,飞行器的热环境面临着新的变化,对热防护提出了挑战。对各类主动热防护方式的原理、研究进展和应用现状进行了归纳总结。结合飞行器未来发展,提出了适应于未来应用的基于相变工质的对流冷却、自适应膜相变冷却和发汗冷却的系统性主动热防护方式。并以此为基础,提出了结合被动、半被动和主动热防护的飞行器全时域综合热管理思路。

Abstract:
New challenge occurs in the field of thermal environment and thermal protection, with the development of space science In the paper, different methods of active thermal protection are reviewed In order to meet the demand of thermal protection system of future aerocraft, a systemic method of phayse-changed thermal protection is put forward, containing convection cooling, adaptive film cooling, and transpiration cooling Furthermore, a new design method called “full-time thermal management” is brought out containing passive, half-passive, and active thermal protection methods
Key words:  Hypersonic vehicle  Active thermal protection  Phase change  Transpiration cooling  Thermal management
