Use of Capacitance Level Gauging for Prelaunch Loading of Slush Hydrogen
It has been shown that a method of loading a specified solid fraction of slush hydrogen aboard a vehicle on the launch pad is feasible. This is based upon a loading equation derived from an energy balance of a slush tankage system over time[1,2] using surface level as a controlling parameter.
