The paper presents a study of the lateral motion stability of a geophysical capsule on the cable suspension using experimental, analytical and numerical methods. The variable area vertical tail (VT) was used to stabilize the capsule. The cable length was also varying. Physical experiment and numerical simulation were introduced to identify two zones of stable motion in the “speed – VT relative area” parameters plane corresponding to the low and high motion speed. Those zone boundaries were in good quantitative agreement; and the left boundary corresponding to the capsule low velocities was also quite accurately predicted by the analytical model. Capsule stability in the “speed – cable length” parameters plane was studied using the analytical method. Decrease in the stable motion zone was established with the increasing cable length. It was shown that an increase in the vertical tail relative area by 4 times led to a decrease in the capsule critical speed by 3 times.
