During the coast phases of space flight, or under orbit conditions, there will be extended periods of time during which high energy liquid propellants and other liquids will be subjected to a state of virtual weightlessness. Liquid orientation is necessary for venting the propellant tank to keep the vapor pressure within allowable limits, for minimizing the boiloff of the cryogenic liquid, and for thermal conditioning of the propellant. Schemes for such liquid orientation also find application in the liquid-oxygen converters of life-support equipment. To restart a high-energy upper stage or a spacecraft from a prolonged coast phase, it is often necessary to guarantee that there will always be liquid propellant located at the tank outlet.
