| 内容記述 | In order to investigate the dynamic stability of MUSES-C capsule, both dynamic-wind tunnel tests and free flight test are carried out. In the wind tunnel tests using free-rotation method, it is measured not only an amplitude of an oscillation caused by dynamic instability in a transonic regime, but also a pressure distribution over the frontal and base surfaces, which reveals that the oscillation is promoted primarily by the force acting on the base surface. Based on the results obtained in the dynamic wind-tunnel test, the aerodynamic moments are described in a simple form on each Mach number. Applying this expression of aerodynamic moments into equation of motion, the prediction of the motion of the capsule become possible. In order to validate this prediction method, the free-flight test using a balloon is carried out. In it the maximum Mach number reaches 1.1, and the oscillation of the capsule during descent from altitude of 36 km is measured. The result obtained in the free-flight test shows the almost same oscillation as the prediction gives. It validates the proposed method in a reasonable accuracy in terms of predicting maximum amplitude of the oscillation. | |||||||||
