Abstract:Waverider is an important designing reference in the design of hypersonic high L/D vehicle. L/D, volumetric efficiency and volumetric are factors to be considered in the designing process. A parameter design model of cone derived waverider was established in this paper and an improved multi-object Genetic Algorithm was chosen as the optimized algorithm. Lift to Drag ratio, volumetric and volumetric efficiency were chosen as optimized objective functions in the multi-object optimization of the cone derived waverider. The optimized model was designed and experiments of attack state's wind tunnel at KD-01 hypersonic gun wind tunnel were conducted. The experiment results were compared with those of CFD. It shows that the model has good L/D performance and can maintain high L/D at certain angle of attack's scope. The CFD results and experiment results are almost identical. The research result is helpful for the hypersonic glide aircraft's aerodynamic design.
