在固体推进剂BDP燃烧模型基础上,引入膏体推进剂燃烧热效应这一新参数将模型推广于膏体推进剂和固体推进剂药浆燃烧研究。模型考虑了氧化剂粒度分布、组分配比、催化剂性能和膏体推进剂燃烧热效应等对燃速的影响,以及药浆固化前后燃速差别。还用靶线法测量了某批次复合推进剂药浆固化前后燃速变化。论文结果可用于膏体推进剂的配方研制和性能预测,以及利用药浆燃速预示固化后推进剂燃速,监控固体推进剂制造质量。
Based on the solid propellant BDP combustion model, a new parameter, which is introduced into the combustion heat effect of the paste propellant, is extended to study the slurry combustion of paste propellant and solid propellant. The model considers the effect of oxidant particle size distribution, component ratio, catalyst performance and combustion heat effect of paste propellant on the combustion rate, and the differences of burning rate before and after curing. The target line method was also used to measure the burning rate of a certain batch of compound propellant before and after curing. The results of the thesis can be used to formulate the formulation of paste propellant and predict the performance of the paste propellant, and predict the burning speed of the propellant after curing by using the pulverized coal combustion speed, and monitor the manufacturing quality of the solid propellant.
