摘要： A wall breaching explosive fragmentation ammunition having a tungsten alloy nose cap with ceramic cone nose which make possible penetration into a hardened target with survivability of the warhead. The ammunition employs a unitary construction with fuze completely within the projectile's shell case. The ammunition has an external plastic rotating band which also encloses an induction antenna. The antenna may signal the fuze on a wire, through a hole in the shell case. The fuze signals may be fed through a gun barrel, then picked up on the antenna. The ammunition also employs a controlled pattern fragmentation mechanism incorporating a patterned plastic liner.

摘要： The invention describes a wall breaching explosive fragmentation ammunition and further a warhead having means for efficiently penetrating concrete and masonry walls, effectively delivering an explosive fragmentation case payload with minimum structural damage to the ammunition's projectile body. The effective wall breaching is achieved using an ogive-shaped, high strength, light weight boron carbide ceramic nose cone cap disposed adjacent to a tungsten alloy nose insert, at the fore of the ammunition. The projectile body is generally cylindrically shaped, preferably made of steel or aluminum to withstand expected forces in the launch environment. The ogive-shaped nose cone may be secured circumferentially to the projectile body with a rubber O-ring to ensure a tight seal. The ogive-shaped nose cone minimizes the penetration resistance force and provides more favorable loading onto the ammunition projectile's wall structure, ultimately minimizing the damage to the projectile's fragmenting case and the explosive payload which follows it. The remaining back projectile area may be filled with propellant. Use of light-weight boron carbide material also minimizes interference with possible steel fragment and tungsten alloy fragment spray. The projectile body includes rotating bands to trap propellant gases from escaping during launch which bands can be attached to the projectile body as a separate part.
摘要翻译： 本发明描述了一种破坏爆炸性碎片的弹药弹，另外一种弹头具有有效穿透混凝土和砖石墙壁的手段，有效地提供爆炸性破碎物体有效载荷，弹药弹丸体的结构损伤最小。 使用位于弹药前方的与钨合金鼻插件相邻设置的ogive形，高强度，重量轻的碳化硼陶瓷鼻锥帽实现有效的壁破裂。 射弹体通常为圆柱形，优选由钢或铝制成，以承受发射环境中的预期力。 ogive形鼻锥可以用橡胶O形圈周向固定在射弹体上，以确保密封。 ogive形鼻锥使穿透阻力最小化，并为弹药的墙体结构提供更有利的载荷，从而最大限度地减少对弹丸碎裂情况的损害以及随之而来的爆炸性荷载。 剩余的后抛射面积可能被推进剂填充。 使用轻质碳化硼材料也可以最大限度地减少对可能的钢片和钨合金碎片喷雾的干扰。 射弹体包括旋转带，用于在发射期间捕获推进剂气体逸出，这些带可以作为单独的部分附着到射弹体。
