Abstract	A theoretical study has been conducted using the NASA-Lewis CEC 76 computer code to model the combustion of pyrotechnic compositions based on magnesium/Teflon/Viton. The study examines the effect of formulation changes on the distribution of reaction products, the reaction temperature and the heat of reaction. The maximum temperature and heat are produced in the stoichiometric fuel concentration whilst the reaction products change significantly with the concentration of magnesium. The Teflon and Viton oxidizers generally have only a minor effect on the system thermodynamics. The major reaction products are magnesium fluoride, magnesium and solid carbon. The proportion of carbon as a combustion product remains relatively constant over a large range of fuel or oxidant concentration. The choice of the optimal MTV composition for IR decoy applications appears to be based more on burn rate and ignitability requirements than on temperature, heat output or optimization of reaction products.
