Electric propulsion systems for space vehicles must be able to restart and operate at zero and low gravity. This operation can be achieved if the tankage delivers only single-phase propellants. The requirements for feed systems of electric engines are described briefly. Also, the 1.85-second drop- test facility is described and the testing techniques are discussed. The minimum energy principle is presented along with a method for determining the direction of mass transfer in tapered tubes and liquid-vapor interface shapes in an annular space between concentric cylinders. Possible feed systems for electric engines are given, which utilize surface tension for fluid positioning and transfer. Zero-gravity and static-fluid configurations in cylindrical and spherical containers are discussed along with experimental observations. The interface 'overshoot' of the equilibrium zero-gravity configuration is also discussed.

This book presents the fundamentals of low gravity fluid dynamics and heat transfer. It investigates fluid behavior in low gravity environments such as those found in earth orbiting and space vehicles. The two major fluid phenomena affected by gravity (buoyancy and surface tension) are treated thoroughly from both the theoretical and applications points of view, and limitations of fluid and thermal responses to gravitational fields in space-based settings are clearly delineated. Summaries of all data available from low gravity flight and terrestrial experiments performed to date are also presented.

The University of Colorado and the National Bureau of Standards have once again served as hosts for the Cryogenic Engineering Conference in Boulder, Colorado. In presenting the papers of this twelfth annual meeting, the 1966 Cryogenic Engineering Conference Committee has again recognized the excellent cooperation which has existed between these two organizations over the past decade with regard to both cryogenic research and conference activity. This cooperation was demonstrated not only at the 1966 Cryogenic Engineering Conference but also at the International Institute of Refrigeration, Commission I Meeting, which was also hosted by these two organizations immediately following the Cryogenic Engineering Conference. These two meetings have provided attendees with one of the most comprehensive coverages of cryogenic topics that has ever been presented at one location. Emphasis on major international advances in helium technology at the International Institute of Refrigeration, Commission I Meeting has been possible largely through the National Science Foundation Grant GK 1116 to the University of Colorado. The Cryogenic Engineering Conference Committee gratefully acknowledges this support because of its valuable international contribution to the Cryogenic Engineering Conference. As in the past, the Cryogenic Engineering Conference Committee is grateful for the continued assistance of all the dedicated workers in the cryogenic field who have contributed their time reviewing the preliminary papers for the program and the final manuscripts for this volume.
