School of Mechatronical Engineering, Beijing Institute of Technology, Beijing 100081, China

摘要

摘要: 传统的破片式防空反导战斗部爆炸后产生的破片杀伤元数量虽多，却不能有效击毁来袭的不敏感弹药，存在威力不足问题，因而限制了其发展。周向多线性爆炸成型弹丸(multiple linear explosively-formed projectile, MLEFP)战斗部爆炸后在周向产生多个高速、大质量、大长径比的对折型线性爆炸成型弹丸(linear explosively-formed projectile, LEFP)，具备击穿、击爆厚壁壳体不敏感弹药的能力，因此在中近程防空反导作战中具备广阔的应用前景。从线性毁伤元的发展和对折型LEFP的成型技术出发，重点分析了炸药装药、药型罩等关键部件影响线性毁伤元成型的研究成果，对比了3种毁伤元初速工程计算模型的理论依据、优缺点等，概括了近年来对折型LEFP侵彻试验结果，最后总结了周向MLEFP战斗部及其毁伤元未来的发展方向。

Abstract: The traditional fragmental warhead used in air defense and antimissile can not effectively destroy the incoming insensitive ammunition due to the weak fragmentations, which limits its development. After explosion of the circumferential multiple linear explosively-formed projectile (MLEFP) warhead, a number of folded linear explosively formed projectiles (LEFP) are produced in the circumferential direction with high speed, large mass and large length to diameter ratio. These projectiles can penetrate thick cases and ignite insensitive ammunitions, so the MLEFP warhead has a great application prospect in the medium-short range air defense and anti-missile system. Based on the development of linear projectile and the forming method of new LEFPs, the influences of charge and liner are focused on. Theories, merits and demerits of three initial velocity models are compared. The results of penetration tests using folded LEFPs in recent years are summarized. Finally, the future development direction of circumferential MLEFP warhead and linear projectile is analyzed.
