To decrease farther the burning rate and the flame temperature of DB propellant with low burning rate and low flame temperature, an experimental study was carried out to explore the effect of a nitro compound on the burning rate and the flame temperature. Series of DB formulations were designed with inorganic lead, organic copper salt and transition metal catalysts. The thermal decomposition and combustion of the propellants were studied by testing the burning rate and PDSC. There are three peaks of heat release on the DSC curves of DB propellant containing the energetic nitro compound, and the heat release temperatures are around 200 ℃, 280 ℃ and 350 ℃, but the third peak is not obvious. Results show that the energetic nitro compounds can effectively decrease the burning rate and the flame temperature of the DB propellant, but increase the pressure exponent, which can be improved by adding catalysts. The collaborations of the energetic nitro compounds and the catalysts can provide DB propellant lower burning rate, lower flame temperature, smaller pressure exponent, and less quantity of decomposition heat.
