AbstractIn this paper, a variable fidelity Kriging model approach, which is also referred to as cokriging, is proposed for efficient aerodynamic data modeling. In this approach, an accurate response surface is constructed by utilizing variable fidelity information. The variable fidelity information can be defined by different physical models, different accuracies of flow simulation as well as combination of experimental data and numerical data. The effectiveness of the developed variable fidelity Kriging model approach is discussed by using EFD/CFD aerodynamic data of a DLR-F6 configuration. The developed approach is promising for accurate aerodynamic data modeling by efficiently integrating EFD and CFD data.
