LLM-105炸药晶形对射孔弹穿深性能的影响

Influence of LLM-105 Power Crystal Form on Penetrating Performance of Shaped Charge

基于正交试验方法,采用X状晶形LLM-105造型粉为主装药装填102型超高温射孔弹,以相同的药型罩结构、装药结构和壳体为条件,通过选择LLM-105传爆药晶形、传爆药药量和传爆孔孔径作为影响射孔弹穿深的主要因素,用L9(34)正交试验表设计了3因素3水平的正交试验方案。试验结果表明,LLM-105传爆药晶形(A)对射孔弹的穿深影响最大,通过对比R值得到的主次关系为A>C>B,根据射孔弹最佳穿深得到了Y状LLM-105传爆药、传爆药药量为2g和传爆孔孔径为4mm的最优组合。

Based on the orthogonal test method, the X crystalline form of LLM-105 power filled 102 ultra-high temperature shaped charge is used as main charge. On the condition that the liner structure, charge form and shell are the same, the LLM-105 booster crystal form, explosive load and boosteraperture diameter are selected as major factors affecting deep-perforation of shaped charge. The 3-factor and 3-level orthogonal experiment plan is obtained using L9 （3^4） orthogonal table. The testing result shows that LLM-105 booster crystal form （A） is the biggest influence factor. By contrasting R, the primary and secondary relationship is A〉C〉B. According to the deepest perforation the optimum assembly is the Y crystal LLM-105 booster, 2 g of booster primer and 4 mm diameter of booster hole.
