Abstract:

Aiming at the problems of numerous and overlapping functional requirements in the design process of aircraft systems, which lead to a large amount of functional redundancy in the design results and the difficulty in fully utilizing the design space, an aircraft integrated design methodology via system action clustering is proposed. Based on the axiomatic design framework, the design process of subsystems and physical domain components is modeled, and the functional requirements, system behavior, and interaction relationships between actions are analyzed in depth. Similar actions are clustered to obtain several action subsets, and the integrated physical domain components corresponding to the action sets are obtained through branch and bound method to achieve integrated design and improve the utilization rate of design space. Taking the integrated design of the top-level subsystem architecture and the power subsystem of the orbital spacecraft as an example, the rationality of the method is verified. The design results showed that the proposed method can effectively reduce the number of subsystems and physical domain components, thereby reducing the redundancy of the aircraft system design.

Key words: integrated aircraft, axiomatic design, action clustering, branch and bound
