The hydroxy-terminated polybutadiene (HTPB) based composite propellants without any metal additive and with varying concentration of metal additives such as iron oxide, copperchromite, strontium carbonate and lithium fluoride have been cast and cured. These propellants have been characterized for density and calorimetric value (cal-val). Further, their temperature sensitivity has also been determined from the burning rates calculated from the P-t profiles obtained on static evaluation of Ballistic Evaluation Motor (BEM) after conditioning at different temperatures. The data indicate that iron oxide is best to enhance burning rates and at the same time, to reduce temperature sensitivity.
