Three-dimensional diagrams for burning rate and temperature sensitivity as a function of pressure and temperature for a 5-ATZ/Sr (NO3)2 mixture
Kazuo Hasue and Makoto Matsukawa


The burning rate of propellants is affected by pressure and temperature. The relation between the burning rate and pressure has been well-studied. However, the effect of the initial temperature on the burning rate has not been investigated quantitatively except in the authors' reports. In this study, the burning rate of 5-amino-1H-tetrazole and strontium nitrate mixtures was examined and an equation for the burning rate as a function of pressure and temperature was obtained. In general, the burning rates predicted by the regression equation were in good agreement with the observed values. The temperature sensitivities were also predicted using the regression equation and compared with the observed values and good agreement was found between the predicted and observed values.
