Burning Rate Equations as a Function of Pressure and Temperature for 1HT/CuO/Additive Mixtures

The burning rate of energetic materials depends on pressure and initial 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. In this study, the burning rates of 1H-tetrazole, copper (II) oxide, and additive mixtures were examined under conditions ranging from 5 to 9 MPa and 243 to 343 K, and equations for the burning rate as a function of pressure and temperature were obtained. In general, the burning rates predicted by the correlation equations were in good agreement with the observed values. The temperature sensitivities were also predicted and compared with the observed values and good agreement was found between the predicted and observed values.
