装药缺陷对熔铸炸药爆速影响的实验研究

为研究装药缺陷对熔铸炸药爆速的影响,采用缺陷分类的研究方法对含有不同缺陷的RDX/TNT熔铸混合炸药进行了爆速实验研究.实验结果表明存在于不同组分中的缺陷会对爆速产生不同程度的影响,TNT中的缺陷使爆速降低幅度最大,若对炸药爆速有较高要求则应重点去除TNT内缺陷,并且推断缺陷尺寸大小可能是影响爆速的决定性因素.对现有ω-Г爆速计算公式进行改进使其能够体现装药缺陷对爆速的影响.

Experimental Research of the Charge Defects' Influence on Detonation Velocity of Melting-Cast Explosive

With the purpose of researching the defects’ influence on detonation velocity of melting-cast explosive,the detonation velocities of RDX/TNT melting-cast explosives with different kind of defects in charge were studied using experimental method.It is found that the defects in different components lead to different influences on detonation velocity,and the defects in TNT decrease the detonation velocity to the great extent.So the defects removal in TNT should be emphasized to ensure high performance of explosive.By inference,the key factor is the size of defects is the key factor to weaken the performance of explosive.Considering the experimental results,the ω-Г equation could be modified and the new equation would materialize the relationship between component density and detonation velocity.
