Application of the Hydraulic System Frequency Response Program to Propellant Feed Systems
Abstract
This thesis applies the Hydraulic System Frequency Response (HSFR) computer program to a liquid propellant feed system analysis. During this investigation, the HSFR program was used to predict the oscillatory pressure, flow and impedance conditions existing in an experimental Saturn V first stage LOX suction duct. When necessary to model this system, additional capabilities were added to the program during this investigation. the results from the HSFR analysis are compared to previously published experimental and analytical data for this system. In this comparison, the HSFR program computed resonant frequencies which were between 0 and 3.6% higher than the test data. The sensitivity of the results to changes in the input model was also investigated. The results from this investigation indicate that the theoretical approach of the HSFR program is valid for large diameter feed systems, and recommendations for further model improvments are made. Originator-Supplied keywords include: Liquid Rocket Feed Systems, Frequency Response, SFR, and Computer program.
