实验研究了含铝AP/HTPB推进剂的配方,讨论了燃速及压力指数与配方参数的关系。结果表明,推进剂燃速随平均AP粒子直径的增大而降低,但在大直径范围,这种趋势减缓。液体二茂铁催化剂可提高50%的推进剂燃速,而固体氧化铁可提高22%。液体二茂铁催化剂能比固体氧化铁更有效地提高燃速。燃速与压力指数的实验结果同燃烧模型的理论计算结果进行了比较,预估结果与实验数据符合较好。 The formula of aluminum-containing AP / HTPB propellants was experimentally studied, and the relationship between burning rate and pressure index and formulation parameters was discussed. The results show that the burning rate of propellant decreases with the increase of average AP particle diameter, but this tendency is slowed down in large diameter range. Liquid ferrocene catalyst can increase the burning rate of propellant by 50%, while the solid iron oxide can increase 22%. Liquid ferrocene catalysts are more efficient at burning rate than solid iron oxide. The experimental results of burning rate and pressure index are compared with the theoretical results of combustion model. The predicted results are in good agreement with the experimental data.
