大孔径双向聚能射孔弹的研究
Study on Big Entry Hole Bidirectional Shaped Charge
摘要
Abstract
A shaped charge model,in which the biconical liner with the two-way charging structure was combined,was designed. Its jet formation mechanism was studied by means of numerical simulations, and the jet parameters were calculated. The obtained results were shown as follows. First, the small cone angle of the liner formed shaped charge jet, and the large cone angle formed explosively over- turned projectile. Second,the velocity of the jet tip and the projectile were respectively 6 250 m/s and 1 620.9 m/s. Third,the length and average diameter of the projectile were 26. 1 mm and 8. 6 mm. Based on the numerical results the jet penetrate formula was amended and then used to calculate the penetration depth of the shaped charge,and the calculated value was 69.6 mm. Finally,an experiment was carried out according to the model,the length and average diameter of the projectile were 28. 1 mm and 8.8 mm. Furthermore, the penetration depth and hole size were 70 mm and 17 mm. Good agreement is among the numerical, theoretical calculation and the experimental results. In addition, the superior penetration performance is proved by the experimental results.关键词
