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。
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.
