Abstract:With the emerging trend of multi-electric/ all-electric vehicles, more and more researchers are engaged in this field. However, the coupling complexity, overall energy efficiency and economic balance of multi-electric/ all-electric vehicle systems are becoming more and more important. Traditional design experience is difficult to apply in the context of new technologies, resulting in increased R D costs and extended R D cycles. In order to meet the above challenges, an energy-optimal architecture optimization method for aircraft is proposed in this paper. By defining architecture optimization process and framework, the definition logic and simplification rules of architecture optimization space are defined. Among many parameters, the energy and weight which have the greatest influence on the performance of all-electric multi-electric vehicle are selected as optimization targets, and the optimization evaluation standard system is established. Combined with multi-objective discrete intelligent optimization algorithm, the effective evaluation and optimization of system architecture are realized. Aiming at the multi-electric development of a certain aircraft, the application practice of this optimization method is carried out, which verifies its effectiveness in improving energy and optimizing system configuration, solves the limitation of traditional design concept in complex flight scenarios, and provides a basis for future research and development of multi-electric/ all-electric aircraft. It provides important theoretical support and engineering guidance
