N2 - One-to-one multi-block structural grid is generated. Analyzing the effect of the grid quality acts on numerical simulation accuracy, the grid generation strategy is investigated. Taking transonic flow of Wing/body/Pylon/Nacelle configuration as a typical numerical example, Navier-Stokes equation is solved based on Roe spatial scheme, and SA turbulence model is adopted. The computational result is compared with wind tunnel experimental data, and shows that the CFD platform is reliable. Discussing the aerodynamic characteristic of DLR-F6 Wing/body configuration, the phenomenon of aerodynamic interference between nacelle and Wing/body configuration is investigated. A platform for aircraft aerodynamic particular design is provided.
