摘　　要：用均匀设计和多元回归分析方法研究了纳米含能有机铅盐n-ONPP、纳米有机铜盐n-PAC和炭黑复配对无烟改性双基推进剂燃烧性能的影响，并建立了多元回归数学分析模型。结果表明，n-ONPP和n-PAC复配或n-ONPP和炭黑的复配，对提高无烟改性双基推进剂2～6MPa的燃速效果显著，而对提高该推进剂在6～22MPa的燃速效果不明显。但一定量且比例适当的n-ONPP、n-PAC和炭黑复配，能显著提高无烟改性双基推进剂在中低压下的燃速，且在中高压段使推进剂出现平台燃烧，但平台燃烧的压强范围随着催化剂比例的不同而不同。理论分析表明，在2～4MPa，对无烟改性双基推进剂燃速起决定作用的是n-PAC和炭黑；n-ONPP、n-PAC和炭黑三者之间的相互作用对燃速也有一定的作用。在6MPa以上，n-ONPP和n-PAC对燃速起决定作用，炭黑起辅助作用。The effect of energetic nano-scale organic lead salt（n-ONPP）, nano-scale organic cupric salt （n-PAC） and carbon black（CB） on the combustion characteristics of smokeless composite modified double-base propellant （SLCMDB Propellant） is studied by uniform design and multi-factors regression analysis method, and the multifactors regression analysis mathematics model （MFRAMM） is proposed. The results show that the mixture of n-ONPP and n-PAC,or n-ONPP and CB can obviously increase the burning rates of SLCMDB propellant at pressure less than 6MPa, while the increase is a little above 6MPa. The mixture of n-ONPP, n-PAC and CB with appropriate ratios, can not only increase the burning rates of the propellant in low and middle pressure zone ,but also make the propellant produce plateau combustion in middle and high pressure zone. But the pressure range of plateau combustion is related to the various ratio of catalysts. Theoretical calculation show that n-PAC and Ct3 play a major role of increasing the burning rate of the propellant in the pressure range of 2--4MPa, the interaction of n-ONPP; n-PAC and CB also has some effect on it. When the pressure is above 6MPa, n-ONPP and n-PAC have major effect on enhancing the burning rate of the propellant ,while CB has supplementary effect on it.
