ABSTRACT

This paper presents the results of a study to compare the stability results of the SPP/SSP code to actual T-Burner experimental data. The SPP/SSP code is the standard solid rocket motor performance program coupled to the Standard Stability Program. Four unique propellants were compared. Two were reduced smoke and two were metallized propellants. Pressure coupled response data was already available for these propellants. This experimental data was evaluated by the T-burner. For the metallized propellants, aluminum oxide particle analysis was also previously performed on the combustion products. The stability analysis was performed using the three- dimensional grain design and ballistic modules and the one dimensional stability module. Types of driving and damping mechanisms included in the analysis included pressure coupling, wall damping and for the metallized propellants, particle damping. The total predicted stability was then compared against the decay and/or growth measured in the T-Burner during a test. The results were surprising in that both the magnitude and trends in the analysis were verified by the data.
