Abstract: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.
