摘要：

The influence on the burning rate was investigated by adding N203. N211 or N401 catalyst (NIKKI CHEMICAL Co., Ltd.) to AP/ (HTPB + IPDI) Composite propellant, of which catalysts were composed by CuO+Cr2O3. CuO+ ZnO. Al2O3 + Cr2O3. respectively. It was found that N203 and N211 catalysts were quite effective on the burning rate and more effective than copper oxide which was added to a composite propellant. Some important views were also obtained from the observations of soot produced by burning and of the surface of the propellant ended in smoke. That is, a straight relationship was seen between the soot yields and the mass burning rates at the different mixing ratio of fuel and oxidizer of the composite propellant. From the observation of the surface of the composite propellant interrupted combustion by SEM, holes of spouting of gases, crystals by condensation of AP vapor and patterns of lines based on the flow combustion flame were seen.
