摘要
对金属热防护系统隔热材料在航天器再入过程中的传热进行了分析,在此基础上,对纤维隔热材料、多层隔热材料和纳米复合材料涂层进行了介绍;比较了3种隔热材料应用到金属热防护系统上的优缺点;最后总结了金属热防护系统隔热材料正向低成本、低质量、低导热系数的方向发展。
Having analyzed the heat transfer of insulations for metallic thermal protection system during spacecraft reentry, 3 kinds of insulations, including fibrous insulation, multi-layer insulation and nano-composite coating, are introduced. Their advantages and disadvantages shown while they are applied to metallic thermal protection systems are compared. Development trend of insulations for metallic thermal protection system which is low in cost, weight and thermal conductivity is summarized.
