主要探讨了ＲＤＸ丁羟推进剂燃烧性能的规律。研究结果表明：高硝胺配方（硝胺炸药含量不小于４０％）中使用过多的细粒度高氯酸铵（ＡＰ），导致压强指数（ｎ）增加；低硝胺配方中（硝胺炸药含量小于３０％），增加４０～６０目的粗ＡＰ，对燃速（ｒ）、压强指数无改善作用；使用细的ＲＤＸ对降低ｎ值有利。还研究了硝胺炸药（ＮＡ）含量以及不同的粘合剂对ｎ值的影响，并给出了平台推进剂配方的ｒ、ｎ结果。
Mainly discussed the RDX butyrolactone combustion performance of the law. The results show that the use of too much fine-grained ammonium perchlorate (AP) in high-nitroamine formulations (nitramine explosives content not less than 40%) leads to an increase in the pressure index (n) Content of less than 30%), the increase of 40 ~ 60 mesh crude AP, no improvement on the burning rate (r), pressure index; the use of fine RDX to reduce n value is beneficial. The effects of nitric amine explosives (NA) content and different binders on the n value were also studied. The r and n results of the propellant formulations were also given.
