Drag Decomposition Analysis of CFD Data of the DLR-F6 Model

The wake integration method, a method that analyzes aerodynamic forces by integration in the wake of a model, was applied to three-dimensional CFD data and a quantitative assessment of aerodynamic forces produced by airplane elements was performed. The method allows the drag force exerted on a body to be decomposed into profile and induced drag components, and provides their distributions. By using this method, a designer can expect to obtain insight into aerodynamic drag production factors from CFD data and wind tunnel wake traverse data. In this study, CFD spatial data of the DLR F6 wing-body model were analyzed and the insights gained into the aerodynamic force distributions were examined.
