Abstract
The use of pressurized gas as a means to control liquid propellant migration in a teardrop tank system subjected to rotational unbalance caused by the detachment of an object from a spinning satellite is investigated. The effectiveness of this control method is ascertained by numerical computation that predicts the stationary position of the liquid propellant in the tank system. A multiloop iteration algorithm is developed to satisfy a continuity condition for the liquid pressure in the pipes connecting the tanks and to determine the position of the center of mass of the whole satellite-liquid system. Numerical results show that the critical total propellant mass below which some of the tanks empty can be controlled to a very small value by increasing the gas pressure, whereas the tilt of the principle inertia axis is reduced to about 50% level of its uncontrolled value by moderate gas pressure and is kept constant with the further increase in the gas pressure.
