Abstract: A passive propellant acquisition and feed system is disclosed which will acquire and feed gas-free propellant in low or zero-g environments during orbital maneuvers which will also retain this propellant under high axially directed acceleration such as may be experienced during launch of a space vehicle and orbit-to-orbit transfers wherein the propellant system includes a dual compartment propellant tank with independent surface tension acquisition channels in each compartment to provide gas-free flow of pressurized liquid propellant from one compartment to the other in one direction only.
