Abstract

This report describes DLR's task 2 contribution to the EUROSUP (Reduction of wave and lift-dependent drag for supersonic transport aircraft) project. EUROSUP task 2 focuses on the evaluation of different cfd methods for numerical flow prediction around supersonic transport configurations at subsonic, transonic and supersonic onflow conditions. DLR uses the Navier-Stokes code (CEVCATS/FLOWer) to calculate numerical flow solutions. Three onflow Mach numbers are investigated at windtunnel conditions. At all onflow speeds two angles of attack on three different dense meshes are investigated. Furthermore free flight conditions for the full scale ATSF-1 generic aircraft are calculated at transonic speeds. Special focus is put on the analysis of viscous flow solutions with respect to numerical accuracy and mesh density effects. Also comparisons with experimental data obtained from an ATSF-1 windtunnel model (scale 1/60) are presented.
