摘要

飞机供配电系统的可靠运行是关系飞机飞行安全的关键因素。以某供配电网络为例介绍了一种适合大型飞机复杂供配电网络的可靠性评估方法,并对该供配电网络的可靠性指标进行了评估和分析。该评估方法利用图论的知识,首先将飞机配电系统抽象为网络图;然后采用深度优先搜索法求出电源点到负荷点的最小路集,进而求出相应的最小割集,找出系统运行的薄弱环节;最后,通过对最小割集的不交化处理结合配电系统部件的原始可靠性数据得出大型飞机供配电系统的可靠性指标。本文方法可以为大型飞机复杂供配电网络的设计和可靠性评估提供参考。

Abstract

Reliable operation of the aircraft power distribution system (APDS) is critical to the flight safety of a plane. In this paper, a reliability assessment algorithm suited to a complex large aircraft power distribution network is introduced, and the reliability of a certain power distribution system is assessed and analyzed. The algorithm abstracts the power distribution system as a network graph. The minimal path sets are searched from the source node to the sink nodes by depth-first search (DFS). Then the corresponding minimal cut sets are found, which can point out the weaknesses in the system operation. Finally the minimal cut sets are converted to disjoint sets. According to the raw reliability data of the components, the reliability of a large aircraft power distribution system can be evaluated. This method has the advantage of strong logicality and universality, which may provide reference for the design and reliability evaluation of a complex large aircraft power distribution network.
