摘要
以固体火箭发动机装药安全性为背景，从高能固体推进剂的燃烧转爆轰（简称ＤＤＴ）危险性、燃烧转爆轰机理和燃烧转爆轰的模拟三方面对该问题的研究工作进行了综述，重点讨论了ＤＤＴ过程中起关键作用的动态压缩现象、压缩燃烧和热点形成机理，以及ＤＤＴ建模中的本构关系和封闭问题，指出了今后进一步研究的方向。
he hazards,the mechanism of Deflagration to Detonation Transition(DDT) and the numerical simulation of DDT for a high energy solid propellant are reviewed with a view of grain safety consideration of solid rocket motor.The key processes in DDT such as dynamic compaction,compressive combustion,hot spot formation,constitutive models and closure are specially discussed in this paper.The subjects for future research are proposed.
