Kurzfassung
The accurate prediction of the sonic boom is essential for the development of a future low boom supersonic aircraft. In this paper the best practice for predicting near-field pressure signatures with the DLR TAU code is applied for geometries and grids provided by the third AIAA Sonic Boom Prediction Workshop. The near-field part of the workshop provided two cases, the Biconvex case and the NASA C608. Both geometries were analyzed by DLR. The Biconvex case is utilized to study shock-plume interactions and the NASA C608 case is used to assess the status of near-field simulations for a realistic low boom flight demonstrator. Results for the DLR TAU simulations on the workshop-provided grids are presented for different grid refinement levels using RANS simulations. In addition to the provided grids, a setup for mixed-element grids with varying setups is described. The predicted near-field signatures agree very well with other workshop participants' results and wind tunnel data.
