摘　　要：飞机燃油系统是飞机获得动力的来源,燃油系统的可靠性对保障飞机安全至关重要。传统故障树分析法(FTA)对多状态下的飞机燃油系统可靠性分析过程较为复杂,工作量较大。GO法适用于多状态下的系统可靠性分析,利用GO法结合SIMULINK仿真平台,计算飞机燃油系统对APU供油的可靠性。针对GO法中第12类操作符路径分离器给出了对应SIMULINK的表达模块。结果表明,使用GO法对飞机燃油系统对APU供油的可靠性分析精确,为多状态下的系统可靠性分析提供了新的思路。Aircraft fuel system is the source of power for aircraft,and the reliability of fuel system is very important to ensure the safety of aircraft.The reliability analysis process of aircraft fuel system under multi-state by traditional fault tree analysis(FTA)is complicated and the workload is large.The GO method is suitable for multi-state system reliability analysis.The reliability of aircraft fuel system for APU fuel supply is calculated by using GO method combined with SIMULINK simulation platform.The corresponding SIMULINK expression module is given for the 12 th operator path separator in the GO method.The results show that the GO method is used to analyze the reliability of APU fuel supply for aircraft fuel system accurately,which provides a new idea for system reliability analysis under multiple states.
