A STUDY OF SYSTEM COUPLED INSTABILITY ANALYSIS TECHNIQUES. PART II.
Abstract
This report is concerned with the study of instabilities, generally referred to as POGO, resulting from coupling between liquid fueled propulsion system and structural dynamics. This report deals with both the liquid system POGO experienced on the Thor and Titan vehicles as well as the gas POGO associated with the pressurization system of the Atlas vehicle. Results of tests and analysis indicate that systems response trends resulting from parameter characteristics affected by both steady state and varying operating conditions can be studied on relatively inexpensive subscale test configurations. Neither tests nor analysis were, however, carried far enough to establish any scaling parameters that could be applied between subscale and full scale systems. (Author)
