摘要： An explosive device, such as a munition or a part of a munition, has an explosive material surrounded by a casing that has one or more voids within the casing. The one or more voids define sizes and shapes of the fragments that the casing breaks into when the explosive material is detonated. The casing may be made using an additive manufacturing process, with the one or more voids fully between an inner surface of the casing and an outer surface of the casing. The voids may substantially define the size and shape of fragments making up a majority of the volume of the casing, such as 75% or more of the volume of the casing. The voids may change direction within the casing, for example branching and intersecting to define a plurality of rectangular (parallelepiped) or other shaped fragments.

摘要翻译： 诸如弹药或弹药的一部分的爆炸装置具有由壳体围绕的爆炸物质，其在壳体内具有一个或多个空隙。 一个或多个空隙定义当爆炸物质被引爆时壳体断裂的碎片的尺寸和形状。 壳体可以使用添加剂制造方法制造，其中一个或多个空隙完全在壳体的内表面和壳体的外表面之间。 空隙可以基本上限定构成壳体体积的大部分的碎片的尺寸和形状，例如壳体体积的75％或更多。 空隙可以改变壳体内的方向，例如分支和相交以限定多个矩形（平行六面体）或其它成形碎片。
