双基推进剂稳态燃速特性计算研究

STUDY ON THE BURNING RATE CHARACTERISTICS CALCULATION OF DB PROPELLANTS

分析了双基推进剂燃烧波的结构特性，建立了一个双基推进剂稳态燃烧模型，利用该模型对现有文献值和实用推进剂配方的燃速特性进行了计算研究。计算结果表明，本模型合理、可行，具有较高的计算精度；双基推进剂燃速取决于其热力学特性和化学动力学性质。

Based on the analyzing the characteristics of DB propellant combustion wave structure and burning rate,a steady combustion model of DB propellant was developed.By means of this model the burning rate characteristics of practical propellant formulations were calulated with satisfactory accuracy and small relalive errors,compared with the literature reported data. Furthermore,the results show that the burning rates of DB propellants depend on their thermal and dynamical characteristics as well.
