高能单元推进剂化学结构和热分解特征与燃速的相关性

Correlation between Structure Thermal Decomposition Characteristics and Burning Rate of the Monopropellants

利用以准一维气相反应流为基础的固体推进剂稳态燃烧模型,研究了高能单元推进剂AP、HM X、RDX、CL-20和NQ的化学结构、热分解特征与燃烧性能的相关性。改进了高能单元推进剂燃速预估模型,使其可由高能单元推进剂的化学结构和基本热分解特性出发,预估单元推进剂的燃烧性能。通过与实测燃速的比较,验证了模型假设的合理性。

The correlation between structure, thermal decomposition characteristics and burning rate of the monopropellants, including AP, HMX, RDX, CL-20 and NQ, was studied by the steady state combustion model based on the single-dimensional gas flow of solid propellants. The combustion characteristics of the monopropellants were estimated by the improved model of burning rate, whose algorithm was based on the structures and thermal decomposition characteristics of the high energy materials. With the help of the comparison of the measured and predicted burning rates of the monopropellants, the rationality of hypothesis of the improved model was substantiated.
