一种射流源和炸药射流感度的研究

Studies on a shaped charge jet and the jet sensitivity of explosives

为了研究各种炸药射流感度,采用多种途径研制了能量输出较稳定的射流源;并用三种方法对射流源能量输出稳定性进行了判定。利用自行研制的射流源对TNT、B炸药J、B-B等多种炸药进行了射流感度的评定试验,获得了多种炸药射流感度的顺序排列结果,并与文献值符合得很好;利用X光机获得了射流头部速度与隔板厚度的关系,并拟合了经验公式。

A shaped charge with steady energy output was developed to study all kinds of the explosives sensitivity to shaped charge jets, and its stability was validated by three methods. The jet sensitivities of such explosives as TNT, Comp B, and JB-B were experimentally evaluated by using the standard shaped charge. The obtained result is consistent with that from literature. The relationship between the velocity of jet head and the cover thickness was determined, and the experimental formula was obtained.
