Abstract
This paper is dealing with the development of a new version of an existing burning model for predicting the burning rate of different pyrotechnic mixtures of magnesium and sodium nitrate. Modifying some parts of the model including burning time of magnesium particles, thermophysical properties of combustion products, and the mixture density, the burning rate has been predicted for different values of mixture composition and combustion pressure. Comparison of the predicted and available experimental values of the burning rates shows good agreements, especially in pressure dependency
