The Research on Aerodynamic Coupling Optimization Model Based on Swarm Formation

为提高小型蜂群无人机紧密编队协同飞行时的整体气动效率,强化系统作战效能,文中以某蜂群无人机平台为研究对象,对其集群编队飞行时的气动耦合问题进行了深入研究。针对不同作战任务场景,设计了几类以典型长-僚机编队为模块单元的编队飞行结构,利用耦合涡流模型的数值仿真方法,完成了双机编队单元的寻优设计,同时基于双机编队单元优化结果,运用遗传算法,得到集群飞行时,各无人机单元气动增量数据传递信息,并辅以计算流体力学仿真验证,确定了完整的气动数据传递体系。最终建立了多任务、多条件、多目标导向的气动耦合优化模型,实现了集群优化飞行策略方法,达到了作战能力倍增的效果。
