"Originally published as 'Theoretical, Quasi-Static Analysis of Cavitation Compliance in Turbopumps', C. Brennen and A. J. Acosta. Journal of Spacecraft and Rockets 10(3):175-180 March 1973. Copyright 1973 by the American Institute of Aeronautics and Astronautics, Inc. Reprinted with permission." The serious POGO instability experienced by many liquid propellant rockets results from a closed loop interaction between the first longitudianl structural mode of vibration and the dynamics of the propulsion system. One of the most important features in the latter is the cavitation compliance of the turbopumps. This report presents calculations of the blade cavitation compliance obtained from free streamline cascade theory and demonstrates the various influences of angle of attack, blade angle, blade thickness and cavitation number. Discrepancies between calculated and experimentally derived values are discussed. 1973-03-00 published Journal of Spacecraft and Rockets 10 3 175-180 CaltechAUTHORS:BREjsr73 TRUE 0022-4650 http://resolver.caltech.edu/CaltechAUTHORS:BREjsr73 You are granted permission for individual, educational, research and non-commercial reproduction, distribution, display and performance of this work in any format.
