The combustion of TiH/sub x//KClO/sub 4/ in a closed system with densities of 50 to 85 percent of the theoretical void free density is investigated. The thermodynamic properties are determined assuming equilibrium conditions using the TIGER computer program. Assuming complete combustion of the TiH/sub x//KClO/sub 4/ and a constant volume for the closed system, the calculated results indicate an equilibrium pressure that increases with the TiH/sub x//KClO/sub 4/ density. The high equilibrium pressures that were calculated suggested that accurate equations of state must be used; therefore the effect of different equations of state was investigated. As expected, the flame temperature and the concentrations of the combustion product species are not strong functions of the TiH/sub x//KClO/sub 4/ density. The calculated temperature of the gaseous products of combustion is close to the isochoric flame temperature. This is due to the fact that the heat loss from the combustion products is neglected and the system is assumed to initially have a negligible amount of gas present. The equilibrium pressure is an important parameter in determining the burning rate of TiH/sub x//KClO/sub 4/ in both the conductive and convective modes. In the conductive mode, the heat feedback from gaseous combustion products depends on the pressure and in the convective mode, both the flow of combustion products into the pores and the heat feedback are pressure dependent. 16 refs., 3 figs., 6 tabs.
