摘　　要：为有效满足民航对于安全性和经济性的综合需求,运用全权限数字电子式系统冗余架构故障的限时派遣决策技术,通过梳理限时派遣分析应用的安全性方法,明确了系统理论分析的限时派遣安全性要素,发展了系统理论分析法辅助进行系统危险性评估方法,并通过建立安全性分析流程对限时派遣分析作出解释。结果表明该方法可以在传统安全性方法上对航空发动机型号适航评估提供系统性参考,也可以为判断故障对发动机LOTC事件的影响等级做出参考。In order to meet the comprehensive needs of safety and economy of civil aviation, this paper uses the decision technology of time-limited dispatch of redundant architecture failure of digital electronic system with full authority, summarizes the security methods of time-limited dispatch analysis and application, defines safety elements of time-limited dispatch in systematic theory process analysis, and uses the method of risk assessment of system aided by systematic theory process analysis to explain the time-limited dispatch by establishing a safety analysis process. The results show that this method can provide a systematic reference for the airworthiness evaluation of aeroengine model on the basis of traditional safety methods, and can also be a reference for judging the impact of faults on engine LOTC events.
