Ground Testing of the HyShot II Scramjet Configuration in HEG

Ground based testing of the HyShot II supersonic combustion ramjet flight configuration was carried out in the High Enthalpy Shock Tunnel Gottingen, HEG, of the German Aerospace Center, DLR. The main focus of these investigations was to obtain surface pressure and surface heat transfer data on the intake and the cowl and body side surfaces of the combustion chamber and the nozzle. Further, high speed flow visualisation of the combustor flow was performed. Two HEG operating conditions which are related to 33km and 27km flight altitude were applied. Computational fluid dynamics (CFD) was applied to support the analysis of the experimental results and for the prediction of the free stream conditions in the HEG test section.
