Static and dynamic aerodynamic wind tunnel tests are performed on the Generic Hypersonic Glide Vehicle 1 (GHGV-1) designed by DLR. Two facilities at DLR Cologne are used to cover a test Mach range from 𝑀𝑎 = 8.8 down to 𝑀𝑎 = 2.0. The performance of the vehicle is investigated with respect to different aspects like trim ability, efficiency of the control surfaces or dynamic stability. Experimental data are compared to the results of a numerical simulation. Additionally, flow structures are visualised by means of Schlieren optic and oil flow visualisation. The aerodynamic performance is found promising so that in a further step the investigation will be extended to the determination of dynamic roll derivatives.
