飞行器体系优化设计问题

针对传统的飞行器设计与体系（SOS）设计相互独立造成的飞行器实际作战效能不足的问题，对同时考虑飞行器与体系耦合设计的飞行器体系优化设计问题展开研究。首先，根据体系工程（SOSE）原理给出了耦合飞行器设计与体系结构设计的飞行器体系优化设计问题的基本概念与通用数学定义；其次，基于多层体系架构，构建了飞行器体系设计优化模型，提出了包含问题定义、体系架构建模、学科建模、优化求解4个步骤的通用建模求解流程；最后，以巡飞/精确打击武器协同作战为例，构建了面向任务成本最低、时间最短的协同作战体系最优化问题并对其进行优化求解。与先设计飞行器后设计体系结构的解耦设计结果对比表明，解耦优化设计忽略了体系结构与飞行器的强耦合特征，无法最优化体系效能；耦合优化设计能够获得体系效能最大化的飞行器设计方案。

Optimal design problem of system of systems of flight vehicle

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.
