A STUDY OF SYSTEM COUPLED INSTABILITY ANALYSIS TECHNIQUES.

Abstract

This report is concerned with the subject of coupled structural/propulsion system instability generally referred to as POGO. The prime objective of the study is to determine the feasibility of using small-scale test configurations to define the parameters critically affecting stability. This report deals with both the liquid system pogo experienced on Thor and Titan vehicles as well as the gas system pogo experienced on Atlas vehicles. This report discusses sub-scale test methods and configurations, as well as analysis of physical generation of cavitation compliance in turbopumps. Preliminary test results indicate that inexpensive commercial turbopumps can be used effectively to study cavitation phenomenon in rocket-engine propulsion systems. (Author)
