STUDY OF INTEGRATED CRYOGENIC FUELED POWER GENERATING AND ENVIRONMENTAL CONTROL SYSTEMS. VOLUME I

Abstract

An investigation was made to determine the feasibility of combining space vehicle subsystems into one integrated system using cryogenic hydrogen and oxygen. The objective of such integration is to produce a lighter and more reliable means of accomplishing the vehicle functions as compared to the use of independent subsystems. Results show that it is feasible to integrate the propellant storage, environmental control and auxiliary power systems. Cryogenic propellant storage and expulsion is best accomplished using overcritical storage techniques though advances in the art will make positive expulsion (bladder) techniques competitive for short duty cycles. The most reliable environmental control systems will use an intermediate heat transport fluid between the heat source and cryogenic heat sink. Liquid or gaseous fluid systems are competitive for this function on a weight basis, but the gaseous appears to be the simpler system. Analysis of APU prime movers indicates that the fourstage hybrid turbine design, based re-entry staging principles offers the best characteristics for use with the high energy propellants. (Author)
