  • Patent number: 5064153
    Abstract: A system in which a surface tension device is connected at the outlet of the propellant tanks, said surface tension device having surface tension gas barrier means, the presence of gas bubbles at the inlet of said surface tension device is detected and a detect signal is produced, said detect signal indicating that the propellant tanks are empty. The detect signal then causes the spacecraft thrusters to be fed from an auxiliary propellant tank. The latter can be implemented inside a main propellant tank.
