摘要： A shock attenuation device is used to reduce the effect of a blast shock by both disrupting the propagation of the shock and by spreading, deflecting, and/or redirecting the shock. The device includes multiple layers of different materials, having different shock transmission impedances, stacked in a direction in which the blast shock travels through the device. At least one of the layers includes a material that crumples in response to the shock, undergoing an inelastic deformation in response to the shock. Also, at least one of the layers includes a material that has a directional shock transmission impedance that provides different shock transmission impedance within different directions within the material. The directional shock transmission material may be oriented such that the preferred direction of shock transmission within the material is oriented away from the direction of in which the multiple layers of material are stacked.

摘要： A fastening system with a rotatable fastener that may secure an aircraft store to an aircraft and may rotate to reduce a drag coefficient of the aircraft store. Reducing the drag coefficient of the aircraft store may increase fuel efficiency of the aircraft store by requiring less energy to propel the aircraft store at a given speed or acceleration.The rotatable fastener allows the aircraft store to attach to the aircraft and to possess a low drag coefficient once the aircraft store is deployed. The rotatable fastener member may be configured to conform to attachment interface standards, such as Standardization Agreement (“STANAG”) 3842 or any other suitable aircraft store attachment interface standard.

摘要： A munition that is adapted to enhance fragmentation effects upon detonation includes preformed fragments between a casing and a shell. The overall mass of the preformed fragments is greater than the overall combined mass of the casing and the shell for enhancing the degree of controlled fragmentation compared to uncontrolled fragmentation. By enhancing the dispersal of controlled fragmentation, the overall fragmentation area coverage and fragmentation pattern density may also be enhanced while limiting travel of the fragmentation beyond the target area for reducing collateral damage. The preformed fragments may fill a continuous volume between the casing and the shell to effectively utilize the munition volume and to maximize the amount of preformed fragments contained within the shell. The preformed fragments may be free flowing pellets that are poured into the volume between the casing and the shell for enhancing distribution of the fragments and for improving assembly of the munition.
摘要翻译： 适用于增强对爆炸的破碎作用的弹药包括壳体和壳体之间的预成型碎片。 预制片段的总体质量大于壳体和壳体的总体组合质量，用于与不受控制的碎裂相比增强受控碎裂程度。 通过增强受控碎裂的扩散，也可以增强整体碎片区域覆盖和碎裂模式密度，同时限制碎片超出目标区域的行进以减少附带损伤。 预成型的碎片可以填充壳体和壳体之间的连续体积，以有效地利用弹药体积并使包含在壳体内的预成型片材的量最大化。 预成型碎片可以是自由流动的颗粒，其被倒入壳体和壳体之间的体积中，以增强碎片的分布并改善弹药的装配。
