Kurzfassung
Damping derivatives of the Exomars capsule have been measured using free oscillation technique in the Trisonic Windtunnel TMK. A cross flexure instrumented with strain gauges measured the dynamic motion of the model in a Mach number range from 1.8 to 3.5. Reynolds number and angle of attack of the capsule were also varied during experiments. The results show a strong dependency of damping derivatives on the Mach number and angle of attack. Compared to the laminar flow on the smooth surface roughness induced transition seems to effect the dynamic stability of the vehicle remarkably.
