Atmospheric entry capsules shaped as spherically blunted, large apex-angle cones are widely used in space missions. Measurements on these types of capsules are performed in the High Enthalpy Shock Tunnel (HEG). The HEG is a large scale facility of the German Aerospace Center (DLR) and it is operated by the Department Spacecraft of the Institute of Aerodynamics and Flow Technology in Göttingen. The experimental investigations are focusing on a free stream Mach number of Ma = 7.4 at a flow speed of 2.4 km/s which corresponds to a total specific enthalpy of 3.2 MJ/kg of the test gas air. Experiments using the free flight model technique are performed. Free flying means that the models are not restricted in their movement during the hypersonic testing in any way. Shock shapes and acting forces on the models can be inferred during the experiments and this data can be used to validate modelling assumptions in the numerical rebuilding of the experiment.
