Kurzfassung
The DLR results for the 4th AIAA CFD Drag Prediction Workshop are presented. Summary: 1. Solar quad-dominant unstructured surface meshes and hex-BL-resolution technique produce very good hierarchy of grids with high quality. 2. Better leading edge and shock resolution with less overall nodes achievable. 3. Aerodynamic coefficients and deltas for medium Centaur/Solar grids are similar. 4. Grid refinement indicates a nearly linear behaviour for 1/N2/3. 5. Wing fuselage separation is influenced by the grid type/size. 6. Trailing edge separation size is mainly influenced by the turbulence model. 7. Trimmed polars: the grid influence is less important than the turbulence model.
