摘要:

为解决单一飞行员驾驶(SPO)模式下综合模块化航电(IMA)系统安全性分析状态空间爆炸、致因关系不明确等问题,首先,定义SPO模式多阶段任务剖面,确定不同任务阶段的IMA系统驻留应用及失效判据;然后,引入级联影响分析(CEA)概念,构建级联故障传播定量计算模型,设计级联失效概率和级联风险系数评估故障在IMA系统中的传播速度、传播范围及影响程度;最后,针对SPO模式案例对比不同任务阶段和不同初始故障条件下IMA系统的故障传播影响趋势。结果表明:所提模型能够表征IMA系统故障的直接影响和间接影响,若以主飞行控制和综合导航为初始故障事件则更容易造成级联失效,需要针对性地对关键驻留应用采取备份、监控或重构措施。

Abstract:

To address the problems of state-space explosion and unclear causal relationships in the safety analysis of IMA system under the future SPO mode, multi-phase mission profiles for the SPO mode were first defined, and the resident applications and fault criteria for different mission phases were identified. The concept of CEA was introduced, and a quantitative computational model for cascading fault propagation was developed. Methods for evaluating the probability of cascading faults and the cascade risk coefficient were designed to assess the propagation speed, scope, and impact severity of faults within the IMA system. Finally, a comparative analysis was conducted under an SPO scenario to examine how cascading faults affect the IMA system across different mission phases and initial fault conditions. The results show that the proposed model can characterize both the direct and indirect impacts of faults in the IMA system. When primary flight control and integrated navigation are initial fault events, cascading faults are more likely to occur, indicating that targeted backup, monitoring, or reconfiguration measures for key resident applications are required.

Key words: single-pilot operations (SPO), multi-phased mission, integrated modular avionics (IMA), cascading effect analysis (CEA), resident applications
