Abstract : Combustion instability data obtained with the same propellants utilizing a T-burner and an L-burner are presented and compared. Analyses for these burners are combined directly with results of a transient analysis of the combustion. The form of the combustion analysis contains two parameters and by the proper combination of the various analyses, these two parameters can be evaluated directly in terms of the experimental variables. The results indicate the parameter values are not consistent nor necessarily realistic. It appears that the theoretical models of transient combustion result in a general, qualitative agreement with experimental data, but that extensive revisions in these models will be necessary in order to obtain quantitative agreement.
