微流星及空间碎片高速撞击航天器风险度分析

摘要

The risk analysis approach has been illustrated. Taking cylinder spacecraft in LEO as an example, the effects of various shield configurations, flight attitudes, thickness of shield bumper and operation duration etc. on meteoroid and space debris impact probability of no perforation have been performed by using risk analysis program. The analysis results were presented.%给出了微流星及空间碎片高速撞击航天器风险分析的方法，并采用风险分析软件，以柱状近地轨道航天器为例，对不同防护结构方案、航天器的飞行姿态、防护屏的厚度以及航天器的运行时间等因素对航天器不发生穿孔损伤的影响进行了分析，给出了分析的结果。
