Abstract

The burning rate of energetic materials 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. The burning rate of a guanidine nitrate / strontium nitrate / basic copper nitrate mixture was examined and an equation for the burning rate as a function of pressure and temperature was obtained. The predicted burning rates 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. The three-dimensional diagrams of the burning rate and the temperature sensitivity are presented. Without complicated calculations, the burning rate and the temperature sensitivity can be predicted at any pressure and temperature within the range of study.
