System Effects on Propellent Storability and Vehicle Performance.
Abstract
The overall objective of this total program was to investigate the tradeoff between propellant storability and vehicle performance for the propellant storage and feed subsystem of a hypothetical LF2/LH2 space propulsion system. Detailed parametric analyses were conducted on such subsystem problem areas as booster-pump feed system utilization, feed line design, venting requirements and provisions, selection of thermal-control coatings, propellant utilization requirements, selection and design of insulation and tank supports, and pressurization system design. Each area was optimized for a spectrum of mission requirements and design ground rules. Design recommendations were derived on the basis of these results. A full-scale, non-flightweight test article utilizing LH2 and LN2 was designed and fabricated to simulate the propellant storage and feed subsystem. This incorporated, wherever practical, the recommendations of the study effort. The apparatus was tested by AFRPL personnel in the AFRPL space simulator to obtain experimental data for correlating the critical thermodynamic analytical models used in this study. This report presents the results of this test data analysis and theoretical correlation with respect to system pressurization requirements and high performance insulation characteristics. (Author)
