The effect of equations of state on transient burning of pyrotechnic materials burning in a closed system is discussed. The effect of condensed species and appropriate equations of state parameters as generated from chemical equilibrium codes such as the BLAKE and the TIGER are presented. It is shown that defining a co-volume for use in transient burning analysis in the presence of condensed species requires careful considerations. A variable co-volume is defined for use in simplified transient burning analysis. Furthermore, its effect on pressure-time history of pyrotechnic materials burning in a closed system is presented. A pressure dependent co-volume for the analysis of a particular pyrotechnic material greatly simplifies its transient burning analysis under zero-volume firing conditions. The formulation of transient burning in a closed system is developed using the NBS equation of state. 9 refs., 3 figs.
