Results from the Second AIAA Drag Prediction Workshop are summarized. The workshop focused on absolute and configuration delta drag prediction of the DLR, German Aerospace Research Center F6 geometry, which is representative of transport aircraft designed for transonic flight. Both wing body and wing body nacelle pylon configurations are considered. Comparisons are made using industry relevant test cases that include single point conditions, drag polars, and drag rise curves. Drag, lift, and pitching moment predictions from several different Reynolds averaged Navier Stokes computational fluid dynamics codes are presented and compared to experimental data. Solutions on multiblock structured, unstructured, and overset structured grids using a variety of turbulence models are considered. Results of a grid refinement study and a comparison of tripped transition vs fully turbulent boundary layer computations are reported. [PUBLICATION ABSTRACT]
