Abstract

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.

Key words: aircraft power distribution system, complex network, reliability, depth-first search, minimal cut set
