设计了以新型碳系纳米材料（CN）为载体的负载燃速催化剂 BC-1／CN 和 BC-2／CN，通过热重（TG）分析和差示扫描量热法（DSC）联用研究了负载燃速催化剂对 AP 热分解行为的影响，研究了负载燃速催化剂种类和含量对 NEPE 推进剂燃烧性能的影响。结果表明，CN 能够增强 BC-1和 BC-2对 AP 热分解的催化作用，从而显著降低AP 的分解温度；随着负载燃速催化剂中 CN 含量的提高，NEPE 推进剂在15 MPa 下的燃速由15．72 mm／s 增至24．68 mm／s，增幅达57％，压强指数由0．60降至0．46；当负载燃速催化剂中 CN 的质量分数为10％时，NEPE 推进剂的燃速高达34．8 mm／s，而药浆的工艺性能没有明显恶化，综合作用效果最好。

Two loading burning-rate catalysts BC-1/CN and BC-2/CN introducing a new type of carbon nanomaterial CN as the carrier were designed.The influence of loading burning-rate catalysts on the thermal decomposition behavior of AP was studied by the TG-DSC coupling method.Effects of variety and content of loading burning-rate catalysts on the combustion properties of NEPE propellants were investigated.Results show that the BC-1/CN and BC-2/CN can enhance the catalytic action of BC-1 and BC-2 on the thermal decomposition of AP and significantly reduce the decomposition temperature of AP.With the increase of CN content in the catalyst,the burning-rate of NEPE propellants under 15 MPa increases from 15.72 mm/s to 24.68 mm/s,which increases by 57%,while the pressure exponent also decreases from 0.60 to 0.46.When the mass fraction of CN in the loading burning-rate catalyst is 10%,the burning-rate of NEPE propellant is up to 34.8 mm/s,while the process performance of the propellant slurry is not significantly deteriorated and the comprehensive effect is the best.
