DLR Results from the Fourth AIAA CFD Drag Prediction Workshop

Abstract

A summary about the DLR, German Aerospace Center, results from the fourth AIAA Computational Fluid Dynamics (CFD) Drag Prediction Workshop (DPW) is presented. Compared to the investigations in the previous three workshops the latest workshop had a stronger focus on drag and trim drag predictions as well as pitching moment calculations. Therefore the new Common Research Model (CRM) developed by NASA's Subsonic Fixed Wing Aerodynamics Technical Working Group is applied. It represents a state of the art transonic transport aircraft configuration and in contrast to the configurations previously used it includes a horizontal tail plane (HTP) with three different tail settings.
