AP/HMX丁羟复合推进剂燃烧转爆轰研究

AN INVESTIGATION OF THE DEFLAGRATION-TO-DETONATION TRANSITION OF THE AP/HMX/HTPB COMPOSITE PROPELLANT

详细地研究了AP/HMX丁羟复合推进剂的燃烧转爆轰（DDT）过程。分析了推进剂颗粒尺寸和形状，装药的氧平衡和渗透性对DDT的影响；讨论了由冲击波诱起爆轰和由燃烧导致爆轰的特点，并且分析了火箭发动机中实际使用的AP/HMX丁羟复合推进剂装药能否产生DDT的可能性。

In this paper,investigations into the deflagration-to-detonation transition (DDT)processes of the AP/HMX/HTPB composite propellants are given in some detail.The effects of the size and shape of propellat grains,oxygen balance of charges and its permeabilities on the DDT are analyzed.Characteristics of both the shock-todetonation transition and the defagration-to-detonation transition are discussed,and possibilities of occurance of DDT in charges of AP/HMX/HTPB composite propellants used in rocket motors are analysed.
