摘要:

本文讨论了硝胺炸药RDX、HMX的热分解及其对固体推进剂燃速的影响.提出了一种适用于AP/RDX(HMX)/HTPB(PU)/Al体系复合固体推进剂燃速预估的计算程序,计算结果与实测值十分吻合.

Abstract:

In this paper the decomposition of RDX, HMX and the its influence on burning rate of solid propellants is discussed.A computer program to calculate the burning rate of AP/RDX(HMX)/HTPB(PU)/A1 composition prOpellants is presented. The quantitative predictions by the method under various propellant compositions and solid particle sizes appear to be basically in accordance with the exprimental results.
