摘要:

在ＢＤＰ模型和ＫＵＢＯＴＡ模型的基础上，提出了适合于有催化剂的改性双基推进剂燃烧模型。计算表明，模型适用于有、无催化剂改性双基推进剂的各种配方，对稳态超速燃烧有较好的模拟效果。

Abstract:

ased on the model BDP and Kubota’s model, this paper provides a revised combustionmodel of catalyzed double-base propellants and makes some calculations using this model. The resultsshow that this model is applicable to both of catalyzed and noncatalyzed double-base propellants withdifferent component. It can well describe the super-rate burning of catalyzed double-base propellants,but it needs further understanding of chemical reactive mechanism to explain the plateau and mesaphenonena of catalyzed double-base propellants.
