The rotational behavior of a lifting capsule was investigated using 3DOF free rotational apparatus in a wind tunnel. Several sizes of glass beads were added on the frontal surface to simulate an ablated surface. The rotational behavior was compared and the effect of the surface roughness was investigated in a flow of Mach 0.3. The roughness of one percent of capsule diameter completely suppressed the rolling motion, which was peculiar to the capsule with smooth surface.
