一种改进的推进剂燃速预示方法

摘要

Propellant burning rate calculations are performed by the use of BDP model for its practical application. Some improvements presented thereafter in burning rate predicitions are included to obtain more reasonable results. Predicted burning rates for AP-HTPB propellants in which AP is unimodal with single average particle size are compared with the experimental data of Reference[2]. A good agreement is found.%把Beckstead-Derr-Price (BDP)模式用于推进剂燃速计算.文中对燃速预测的某些改进使计算的结果更为合理.对单规格AP-HTPB推进剂,为计算方便起见其配方中只采用了单一规格的平均粒度的AP,所预测的燃速值与文献[2]中的实验结果进行了比较,其间良好吻合.
