随着对太空探索的深入,空间飞行器所面临的环境也越趋恶劣:太空飞行过程中的高温羽流防护,高速返回再入过程中高温气动加热;长时间日光下飞行会使飞行器表面温度越来越高;一些星球上高温的大气环境导致人类现有制造飞行器的材料无法抵挡。本文搜集国内外先进热防护系统研究资料,了解重点发展方向,介绍了我国神舟飞船热防护材料以及已经开发出的新型轻质高效热防护材料,为我国今后用于恶劣环境下的飞行器材料提供一些信息和材料基础。
With the deepening of space exploration, space vehicles are facing even worse environment: high-temperature plume protection during space flight and high-temperature aerodynamic heating during high-speed return and reentry; long-time sunlight flight will make aircraft surface temperature more The higher the temperature, the hotter the atmosphere on some planets leads to the unmanageable material available to mankind to make aircraft. This paper collects the research materials of advanced thermal protection system both at home and abroad, understand the key development direction, introduces the thermal protection material of Shenzhou spacecraft and the new light and high efficient thermal protection material that have been developed, and provides some materials for aircraft materials used in harsh environment in our country Information and material base.
