Abstract : The objective of this 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 having the general features itemized in Table I and the duty cycles covered in Table II. The approach that will be 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 coordinate with RPL personnel to implement this test plan; and (4) use the test results to appropriately modify the analytical models and reoptimize the vehicle design parameters where necessary. This approach shall be implemented by a nine-phase program as summarized below. (Author)
