摘要
通过运用故障树分析（ＦＴＡ）技术，对某运载火箭控制系统点火时序电路及紧急关机电路进行可靠性分析，发现了在设计中虽采取了冗余等可靠性设计措施，但仍存在着不易发现的薄弱环节，对此，提出了改进措施及建议。
By using Fault Tree Analysis (FTA) technology, we have analyzed the igniting sequential circuit and emergency cut-off circuit of a launch vehicle control system. Some problems had been found through FTA, even though some reliability design methods had been applied in the circuit design, for example, 2/3 vote. For these, improvement methods and suggestions had been provided in the paper.
