微流星体及空间碎片是航天器的公认威胁 .微流星体及空间碎片的高速撞击能导致航天器严重的损伤和灾难性的失效 .防护结构设计是航天器设计的一个重要问题 .在综合分析国际上已采用和研究航天器微流星体及空间碎片防护结构防护性能预报方程的基础上 ,给出了不同防护材料和结构形式防护在超高速撞击下的撞击极限曲线 .讨论了防护结构参数变化对防护性能的影响 .通过曲线分析得出各防护结构在第一门槛值速度区间的防护性能是比较低的 ,正撞击损伤更严重 ,填充防护结构的性能优于其他防护结构
Micrometeoroid and space debris are the accepted threats of spacecraft.The high-speed impact of micrometeoroid and space debris can lead to serious damage and catastrophic failure of spacecraft.Design of protective structure is an important issue in the design of spacecraft.In a comprehensive analysis Internationally, the impact prediction curves of the spacecraft micrometeoroid and space debris protection structures have been adopted and studied, and the impact limit curves of the different protection materials and structure protection under hypervelocity impact have been given. The changes of the parameters of the protection structures On the protective performance.According to the curve analysis, the protective performance of each protective structure in the first threshold speed range is relatively low, the impact damage is more serious, the performance of filling protective structure is superior to other protective structures
