Nucleonic Propellant Gaging and Utilization Systems for Space Vehicles

A typical nucleonic propellant gaging and utilization system for space vehicles is described, together with a detailed discussion of the individual components. Photographs of prototype installations and test results of these configurations are presented to substantiate the theoretical analyses for signal propagation and radiation pattern mapping including measurements under zero gravity conditions. The results are concluded as verifying the nucleonic measurement system capability for providing an accurate, highly reliable approach to maximum cost effectiveness of propellant gaging and utilization system design.
