 note = {The MUSES-C sample return capsule is expected to carry back to earth the collected sample from Asteroid 1998SF36 in 2007. The capsule has a blunted-cone forebody with a semi-apex angle of 45 degree, and has no active equipment for attitude control. Therefore, it should have passive aerodynamic stability all over the reentry flight. For a dispersion analysis of a landing point, it is indispensable the aerodynamic characteristics of the SRC over an entire flight regime, from rarefied gas to low-subsonic regime. The damping characteristics of the capsule over the entire flight is also required for a six-degree-of-freedom motion analysis. In the present study, the data base of the aerodynamic characteristics of the capsule were constructed by a combination of various available techniques. The source of the data were mainly obtained by a series experiments in several types of wind tunnels. Special attention was paid on the transonic damping in pitch, since it is known that a relatively flat-shaped body has a tendency of the dynamic instability in transonic regime. The grown oscillation might result in a failure of the parachute deployment. This damping-in-pitch characteristics were investigated by the special device which enabled the capsule model to rotate freely around the pitch axis in wind tunnels. A series of free-fall tests from balloons was conducted to validate the transonic and subsonic aerodynamic characteristics with emphasis on the damping-in-pitch characteristics. Another attention was paid on the damping-in-roll characteristics to ensure the spin during the reentry. The details of the experiments and the data base were described herein., 資料番号: SA0200033000},
