Abstract: To address the insufficient actual operational effectiveness of the flight vehicle caused by the independence between the traditional flight vehicle design and the System of Systems (SOS) design, and the defects of manual iteration, the optimal coupling design of flight vehicle and system of systems is studied in this paper. First, based on the principle of System of Systems Engineering (SOSE), this paper presents the basic concept and general mathematical definition of the optimal design of the flight vehicle system of systems combined SOS architeclure design and flight vehicle design. Then, based on the multi-level system of systems architecture, a model for the optimal design of the flight vehicle system of systems is built, and a general modeling and solving process for such a problem is proposed, which includes the definition of the problem, its architecture modeling, its discipline modeling, and its optimization of problem solving. Finally, taking LAM/PAM cooperative weapon system combat application case as an example, an optimization task of pursing the shortest attacking time and the lowest cost is built and solved. Calculation results show that the design result of the decoupling design mode, which designs the flight vehicle first and then the system of systems, cannot meet the demand of combat operations, but the design result of the coupling design method can complete the combat mission much better and produce flight vehicle conceptual design schemes that can maximize the effectiveness of the system of systems.

Key words: flight vehicle design, system of systems engineering, multidisciplinary design optimization, multi-objective optimization, LAM/PAM cooperative weapon system
