中文摘要:
      从无人机外形设计的总体、气动设计要求出发,根据多目标优化的基本概念,将Pareto方法与遗传优化搜索相结合,并采用了群体排序、基于共享机制的小生境等技术,使解集具有良好分布特性。在此基础上建立了一套可满足无人机气动外形综合优化设计优化模型和优化方法。针对无人机外形优化设计要求,提出了复杂外形参数化和设计变量的选取原则。根据某无人机的设计要求,以亚声速和超声速气动特性为设计目标的无人机外形综合优化设计,取得了良好的优化设计结果。
英文摘要:
      According to requirements of configuration and aerodynamic in UAV configuration design, the optimization design model and analysis method of UAV aerodynamic layout optimization design are built by combining the Pareto method and genetic algorithm based on the concept of multiobjective optimization. To get the results with favorable distribution, the population sorting, Niche faring are used. For the design requirement, the parameterization of complicated UAV geometry and design variables selecting principles are presented. To meet the design requirement, the UAV configuration integral optimization is carried out by the subsonic and supersonic aerodynamic performance , and the optimization result is satisfying.
