DNTF基炸药燃烧转爆轰影响因素实验研究
Experiment Study on the Influence Factors of the Deflagration to Detonation Transition for DNTF-based Explosives
摘要
Abstract
To study the effective regulation and control technology of the deflagration to detonation transition (DDT) process for DNTF-based composite explosive,the effect of ignition charge mass,DDT tube wall thickness constraint and molding way etc.on the performance of DDT for DNTF-based composite explosive was investigated by the coaxial ionization probe test technology.The test results were analyzed from the view of the change in rupture state of DDT tube,wave front velocity at different location of DDT process and inducement detonation distance etc.Results show that the DDT tube wall thickness constraint has no significant effect on the inducement detonation distance of DDT for DNTF-based composite explosive,which is at about 375 mm,but decreasing wall thickness can make the duration time of deflagration stage increase and the initial velocity to detonation reduce to 551 5 m · s-1.Increasing ignition charge mass has no significant effect on the reaction violence of DDT for DNTF-based composite explosive,but it can reduce the duration time of initial combustion and detonation induced distance.The duration time of initial combustion,duration time of deflagration and detonation induced distance of the pressed molding specimen are greater than those of the cast specimen,but there is no obvious difference in the violence of the reaction.关键词
