Analysis of the Pressurizing Gas Requirements for an Evaporated Propellant Pressurization System
This paper describes the results of an analytical and experimental program for studying the expulsion of liquid from a missile propellant tank by means of an evaporated propellant. The analytical study has been directed toward obtaining a method for accurately determining the pressurizing gas requirements for expulsion. The test program was conducted to determine the required empirical coefficients for the analysis, to provide a means for checking the analysis, and to permit detailed studies of the phenomena taking place as a result of the dynamic and thermodynamic conditions imposed on the system. Although several propellants are being investigated in this study, only the results of the liquid-hydrogen program are presented in this paper.
