The effects of some catalysts on the thermal decomposition of HMX/AP/HTPB propellant are studied with the differential scanning calorimetry(DSC).The experiments demonstrate that the mixture of HMX/AP/=1/1(weight)has specific decomposition characteristics.The catalysts(such as PbO2
Na2S2O8
Fe3O4
CO2O3 and Pb Cr2O4)which are able to increase the burning rate of the propellant
primarily rais6e chemical reaction rate in gaseous phase.
