摘要/Abstract

摘要： 为提高爆炸成型弹丸（EFP）的命中概率和炸药装药利用率，通过在药型罩上预制沟槽和开为提高爆炸成型弹丸（EFP）的命中概率和炸药装药利用率，通过在药型罩上预制沟槽和开孔的办法，设计了一种新型整体多枚爆炸成型弹丸(MEFP)战斗部。靶场静爆试验和数值模拟表明，这种MEFP战斗部能够产生预期的3枚成型弹丸。每枚成型弹丸均可穿透两层15 mm厚叠放的25SiMnMo装甲板，试验靶板上弹孔呈等边三角形分布，有效地提高了命中概率。这种MEFP战斗部对靶板总的穿透毁伤面积较结构相似的单枚EFP提高3倍以上。

Abstract: In order to improve the hit probability of explosively formed penetrator (EFP) and the efficiency of explosive charge, a new integral multi-explosively formed penetrator (MEFP) warhead was presented, of which the holes and grooves were fabricated on the whole liner. The static explosion test and numerical simulation of this warhead show that three EFPs were formed out, and each EFP penetrates 2×15 mm 25SiMnMo armor plates. The penetration holes were distributed in the form of equilateral triangle on the target, and the hit probability was improved greatly. The penetration area of MEFP was increased over three times compared to regular EFP with similar structure.

Key words: explosion mechanics, multi-explosively formed penetrator warhead, hit probability, groove, efficiency of explosive
