Optimized Design of Osculating Cone Derived Waverider Based on Surrogate Model
In order to find optimum aerodynamics performance waverider shapes with lower compute costs, this paper presents a surrogate model based multi-objective design approach for conceptual design of an osculating cone derived waverider shapes.By parameterized the design process of osculating cone derived waverider，it can generate waverider shapes from changing the parameters reasonably.Latin hypercube sampling is selected as design of experiments method, radial basis functions (RBF) is introduced as approximation method into construct surrogate model, and goodness of surrogate model is valued by calculating root-mean-square error of additional points.Aerodynamic data of the osculating cone derived waverider are collected at Mach 6 with a height of 30km.The multi-objective evolutionary algorithm NSGA-Ⅱ which produces a set of Pareto solutions is employed as optimization strategy to obtain trade-offs between maximization of lift-to-drag-ratio and volumetric efficiency．
