System Effects on Propellant Storability and Vehicle Performance

摘要

The objective of the program is to study the influence of pertinent system design features and parameters on propellant storability and vehicle performance for a hypothetical LF2/LH2 maneuvering space propulsion system. The approach taken is to (1) perform theoretical studies on each basic sub-system and use the resulting data to optimize critical parameters for the overall system; (2) design and fabricate a test apparatus for evaluating as completely as possible, in a space simulation chamber, the analytical models used and the appropriate influence coefficients for inclusion into these models; (3) evolve a test plan for utilizing this test apparatus; and (4) use the test results to appropriately modify the analytical models and reoptimize the vehicle design parameters where necessary.
