摘要： A jacketed bullet having a penetrator constructed of a hard material in line with a slug having a lower modulus. At least a portion of both the slug and the penetrator are then encased by a metal jacket. A plurality of circumferentially spaced and axially extending flutes are formed along the slug and possibly the penetrator. These flutes receive deformation of the jacket upon firing of the bullet into a rifled gun bore to thereby reduce friction between the bullet and the gun bore during operation.
摘要翻译： 一种夹套子弹，具有由硬质材料构成的穿孔器，该硬质材料与具有较低模量的块状物一致。 然后，两个塞子和穿透器的至少一部分被金属护套包住。 沿着塞子和可能的穿透器形成多个周向间隔开并且轴向延伸的凹槽。 这些凹槽在将子弹击中膛口枪孔时接收夹套的变形，从而在操作期间减小子弹与枪孔之间的摩擦。

摘要： A method of manufacturing and optimizing energetic propellant grains includes generating an optimal surface area to mass fraction burned ratio profile for a predetermined solid structure including propellant grains; using the profile as a target function of a topological optimization process to generate a 3D form of a propellant grain; developing a negative of the 3D form of the propellant grain; mixing and densifying the negative with an energetic material in an uncured form in a mixer to create a structure including the energetic material and embedded negative; and solvating the negative from the structure, wherein the negative comprises a 3D propellant grain. The developing of the negative of the 3D form of the propellant grain may occur using a predetermined material in an additive manufacturing process. The negative may be soluble in the predetermined material, and the energetic material may be insoluble in the predetermined material.
