Reliability Evaluation of Aircraft Power Supply System Based on Factoring Algorithm

The reliable operation of the aircraft power supply system is an important factor in ensuring the safe flight of the aircraft. Taking an aircraft HVDC power supply system as an example, a reliability assessment method suitable for large aircraft power supply networks is introduced. With the goal of ensuring that all bus bars are supplied with power, the method uses graph theory and other related knowledge to transform the aircraft power supply network into a cyclic directed rooted communication network. Thereby converting the problem into solving the network%s rooted communication reliability; then using factoring algorithm performs binary tree decomposition on the generated rooted communication network to gradually reduce the network scale, and put forward the rules for selecting points that can improve the efficiency of the algorithm. Finally, in the process of generating the binary tree, the overall reliability function of the network can be obtained, so that typical reference indicators such as reliability and MTBF can be calculated.
