Research on Multiple Failure Analysis Method for Dynamic Reconfiguration Flight Control System of BWB Aircraft

For the multifunctional configuration of control surfaces in the flight control system of BWB aircraft, and the complex redundancy management and reconfiguration capabilities implemented in the event of failures, a multiple failure analysis method based on multiple failure state space is proposed. Taking a certain type of BWB aircraft as an example, a failure relationship matrix is defined to automate the analysis of Failure combinations under different state spaces. The results show that this method can effectively analyze the evolution process of system failure states and safety impacts across different state spaces, systematically identifying failure modes and the processes of redundancy switching and reconfiguration.
