摘　　要：为提高通用航空飞行器(Common Aero Vehicle,CAV)的设计水平,采用三种参数化方法对两种不同类型的CAV构型进行参数化建模研究,并结合工程估算方法和优化算法分别对CAV进行了以最大升阻比为目标的构型优化以及以最大升阻比、最大容积率和最小热流量为目标的多目标设计优化。结果发现,最大升阻比大的构型往往比较细长,升阻比、容积率和热流量无法同时实现最优,仅以升阻比为优化目标所得构型很难符合实际需求。多目标优化过程得到了三个优化目标下的非劣解集,可为工程中的CAV构型选择提供参考依据。In order to improve the design level of common aero vehicle(CAV),three parametric methods are used to carry out parametric modeling studies on two different types of CAV configurations.Combining engineering estimation methods and optimization algorithms,the aircraft configuration optimization with the goal of maximum lift-to-drag ratio and multi-objective design optimization with the goals of maximum lift-to-drag ratio,maximum volumetric efficiency and minimum heat flow are carried out respectively.The results show that the configuration with large maximum lift-to-drag ratio is often relatively slender,and the lift-to-drag ratio,volumetric efficiency and heat flow cannot be optimized at the same time.The configuration only taking the lift-to-drag as the optimization goal is difficult to meet the actual needs.The multi-objective optimization process obtains the non-inferior solution set under the three optimization objectives,which can provide a reference for the selection of CAV configuration in engineering.
