    • A hinged explosively formed projectile warhead system eliminates exposure of soldiers to harm in wall breaching operations by providing a lethal mechanism that can be deployed at safe distances, simultaneously breaching a man-sized hole and removing one or more rows of rebar in reinforced concrete structures or barriers. The warhead system employs both a missile system and explosively formed projectile warhead technology delivered to the target from a tube launched platform. A set of warhead arms is attached to the aft end of a missile body by means of a set of hinges. The warhead arms are initially folded against the missile body. After launch of the warhead system, the warhead arms fold away from the missile body. The angle at which the warhead arms are folded from the missile body determines the area of a hole breached by the warhead system in a reinforced concrete target.

    • A single stage kinetic energy warhead using multiple explosively formed projectile (EFP) liners in a stacked configuration is capable of breaching intermediate barriers and defeating a primary target. The main explosive charge is detonated and the subsequent shockwave causes the front liner to be shaped to breach an intermediate barrier. The main liner is formed into a more compact rod-shaped projectile designed to defeat the main target. The weight and volume of the stacked liner configuration of the present system is significantly lower than the weight and volume of current systems. The present system requires a single firing explosive train eliminating developmental cost and complex fusing. The present system utilizes explosive detonation, simplifying the delivery of a projectile and eliminating the need for a missile delivery system. The size and simplicity of the present system allows for portability and use by an individual.

    • The dynamically configurable controlled fragmentation insert mechanism of this invention includes an assembly of three or more sleeves with differing through hole patterns thereon, that fit inside the shell casing. The individual sleeves can move independently of one another and a simple pinning mechanism holds the parts in place for a selected configuration. The warfighter can realign the insert sleeves by to create different geometric patterns of holes, each designed to engage a different target set with optimally sized fragments. The aligned patterns of holes creates individual geometric shapes that focus high-velocity jets to cut into the steel shell casing to correlate to the through-holes in the aligned patterned sleeves. Realigning the insert sleeves changes the through-hole pattern to produce different fragment sizes and mass distributions. To defeat light armored vehicles for instance, a warfighter can deploy a sleeve hole pattern to produce larger fragments with greater penetrating power, while to engage enemy troops for instance, a warfighter can “dial in” another hole pattern through the fuze assembly to otherwise produce a much larger number of smaller, lighter fragments.
    • 本发明的可动态配置的受控破碎插入机构包括三个或更多个具有不同通孔图案的套筒的组合件,其装配在壳体壳体内。 单独的袖子可以彼此独立地移动,并且简单的钉扎机构将部件保持在所选配置的适当位置。 战斗人员可以通过创建不同的几何图案的孔来重新对准插入套筒,每个设计用于接合具有最佳尺寸碎片的不同目标组。 孔的对准图案产生单独的几何形状,其聚焦高速射流以切入钢壳壳体以与对准的图案化套筒中的通孔相关联。 重新调整插入套管会改变通孔图案,以产生不同的片段大小和质量分布。 例如,为了打败轻装甲车,战斗人员可以部署袖孔图案,以产生更大的穿透力的较大的碎片,例如在与敌军接触的情况下,战斗人员可以通过引信组件“拨入”另一个孔模式,否则产生 更大的数量更小,更轻的碎片。

    • A segmented, kinetic energy projectile is formed by stacking several liners in a single warhead, for effectively producing a longer penetrator capable of greatly enhancing penetration. Each individual liner forms a separate penetrator, so that the liners are successively fired and allow for a greater overall target penetration. In one embodiment, the flight path of at least one liner is diverted from the flight paths of the other liners, so that the liners could attack several adjacent targets or provide multiple penetrations. The EFP assembly has the additional capability of utilizing a single warhead that incorporates multiple hits mechanisms. The EFP assembly includes multiple liners that are separated by multiple separators. The separators are non-symmetrically disposed relative to each other, in order to divert the liners toward multiple targets. The liners are diverted from a reference trajectory because the separators impart different angles to the liners. Alternatively, the liners can be deviated from the reference trajectory, by varying the densities of the liners, or by varying their thicknesses.
    • 通过在单个弹头中堆叠多个衬垫形成分段的动能弹丸,用于有效地产生能够大大增强穿透力的较长穿透器。 每个单独的衬垫形成单独的穿透器,使得衬垫被连续地烧制并允许更大的总体目标穿透。 在一个实施例中,至少一个衬套的飞行路径从另一个衬垫的飞行路径转向,使得衬垫可以攻击几个相邻的目标或提供多个穿透。 EFP组件具有使用包含多个命中机构的单个弹头的附加功能。 EFP组件包括由多个分离器分隔的多个衬垫。 分离器相对于彼此不对称地设置,以便将衬垫转向多个靶。 衬垫从参考轨迹转向,因为分离器赋予衬垫不同的角度。 或者,衬垫可以偏离参考轨迹,通过改变衬垫的密度,或通过改变它们的厚度。
