  • For aerodynamic shape optimization,the approximation management framework(AMF) method was used to organize and manage the variable-fidelity models.The method can take full advantage of the low-fidelity,cheaper models to concentrate the main workload on the low-fidelity models in optimization iterative procedure.Furthermore,it can take high-fidelity,more expensive models to monitor the procedure to make the method globally convergent to a solution of high-fidelity problem.Finally,zero order variable-fidelity aerodynamic optimization management framework and search algorithm were demonstrated on an airfoil optimization of UAV with a flying wing.Compared with the original shape,the aerodynamic performance of the optimal shape is improved.The results show the method has good feasibility and applicability.
