Kurzfassung
Dynamic stability of the IXV configuration has been investigated using free oscillation measurement technique in the Trisonic Windtunnel (TMK). In the transonic Mach number range an escalating behavior of the pitching moment damping derivative has been observed, although the vehicle is statically stable. At Mach 0.8 the vehicle showed the most unstable behavior. The instability becomes weaker with increasing Mach number. At Mach number 1.1 the vehicle is only slightly instable. In the supersonic regime experimental data showed an excellent repeatability. All supersonic tests provided a negative pitching moment damping coefficient, i.e. dynamically stable vehicle behavior.
