Abstract: The spoiler redundancy system improves the reliability of new energy electric aircraft. A reliability model of electric airplane spoiler systems is established by the GO method, a SIMULINK simulation interface designed, and a new operation module provided for operator 11. To effectively reduce the workload of the traditional GO method in redundant system modeling, we design a kind of moment operator for the spoiler redundant system, with the results verified by fault tree analysis. The results show that the method proposed in this paper is feasible, therefore providing a new idea for reliability analysis of the spoiler system of new energy electric aircraft.

Key words: GO method, electric planes, matrix operation, spoiler systems, reliability
