摘要
根据中国航天系统安全性分析的现状 ,对在美国国家航空航天管理局 ( NASA )、欧洲空间局( ESA )均得到广泛应用的航天系统安全性分析概率风险评估 ( PRA)方法加以改进 ,使其适用于我国的航天系统 ,并且将改进后的 PRA方法 (简称为 CPRA)运用于我国某一型号运载火箭的重要子系统的具体安全性分析 。
On the basis of the practical situation of safety analysis of space systems in China, we improved probabilistic risk assessment approach, which has been applied broadly in NASA and ESA, so as to make it suitable to our country's space systems. We have applied the improved PRA approach (named CPRA) to analyze the safety of some important subsystems of one particular type of launch vehicle of China, then to analyze the safety of the whole launch vehicle in the not\|so\|far future.
