    • A fragmenting warhead is provided having an outer cylindrically shaped hollow steel shell which can be selectively detonated into different fragment types and sizes. The warhead has a plastic liner within said shell, and a core of explosive. There are a number of insulated wire grids of high electrical resistance which will heat when an electrical current is provided thereto located in intimate thermal contact with the explosive, each grid corresponding to a fragment type and size for selection by providing electrical current to that selected grid. Heat flux is caused when an electrical current runs through a particular grid and this selectively melts explosive in the near vicinity of such grid, then a detonation of the explosive core will result in a fragmentation type and pattern corresponding to that grid type and pattern. An ignition propellant train may also be selectively associated with wires on the grids to further selectively detonate the explosive. The plastic liner serves not only as electrical insulation, but also increases grid structural integrity, ease of manufacturing, thermal insulation, and IM qualities of the warhead.
    • 提供了具有外圆柱形中空钢壳的碎片弹头,其可以选择性地引爆成不同的碎片类型和尺寸。 弹头在所述壳体内具有塑料衬垫,并具有爆炸物的核心。 存在许多具有高电阻的绝缘线栅,其在提供电流时加热,位于与爆炸物紧密热接触的位置,每个栅格对应于片段类型和尺寸,以通过向选定的栅格提供电流来选择 。 当电流穿过特定格栅时会引起热通量,并且在这种格栅附近选择性地熔化爆炸物,则爆炸核心的爆炸将导致与该格栅类型和图案相对应的破碎类型和图案。 点火式推进剂列车也可以选择性地与网格上的电线相关联,以进一步选择性地引爆爆炸物。 塑料内衬不仅用作电气绝缘,而且还增加了电子束的结构完整性,易于制造,隔热和IM质量。

    • A fragmentation warhead includes a cylindrical body, a pair of concentric cylindrical liners made of plastic, and an explosive charge disposed within the innermost liner. The innermost liner includes patterns formed thereon of recessed areas and solid liner elements. The outermost liner's interior surface includes patterns formed thereon of raised areas and solid liner elements. The outermost cylindrical liner is arranged to be adjustable relative to the innermost liner through rotation or translation. The explosive charge is disposed adjacent to the interior of the innermost cylindrical liner. Upon detonation of the explosive charge and because of the random dampening and temporal delay in transmitting the detonation energy through various locations of the randomly aligned cylindrical liners, the warhead body is caused to shear and break into fragments with different sizes. It can be understood that adjustment of the outermost cylindrical liner can be used to influence the size of fragments ultimately generated when the warhead breaks apart through detonation.
    • 分裂弹头包括圆柱形主体,一对由塑料制成的同心圆柱形衬套,以及设置在最内侧衬套内的炸药。 最内层的衬垫包括形成有凹陷区域和固体衬里元件的图案。 最外层衬里的内表面包括在其上形成凸起区域的图案和实心衬垫元件。 最外面的圆柱形衬套布置成通过旋转或平移相对于最内侧的衬垫可调节。 炸药装置靠近最内圆柱形衬套的内部。 在爆炸炸药爆炸时,由于随机阻尼和随时间的延迟,将爆炸能量传递到随机排列的圆柱形衬套的各个位置,造成弹头体剪切并破碎成不同尺寸的碎片。 可以理解,最外面的圆柱形衬套的调整可以用于影响当弹头通过爆炸分解时最终产生的碎片的尺寸。

    • A fragmentation warhead includes a cylindrical body, and an explosive charge disposed within the innermost part of the warhead body. Upon detonation of the explosive charge, the warhead body is ultimately caused to shear and break into fragments with controlled sizes, shapes. Metallurgical composition of the warhead body can be used to influence the size of fragments ultimately generated when the warhead breaks apart through detonation, since the size and positioning of fragments in the warhead body is preselected. Fabrication of explosive fragmentation ammunition with preformed fragment tungsten alloy fragmenting shells of complex shapes and small and medium calibers is provided in this invention. According to an embodiment of this invention, fabrication begins with “green” tungsten alloy fragment pellets of a given, full strength, enwrapped in a green lower strength matrix alloy. The product is said to be green because tungsten is largely used to replace other metals such as lead which may be considered more toxic. Next, in the process is pressing to the approximate shape desired of the bulk of the green fragments and matrix mix. This is ultimately followed up with sintering. According to an embodiment of this invention, the sintering process will ultimately result in full strength preformed fragments of tungsten alloy enwrapped in a low strength matrix of tungsten alloy, sized to a desired shell shape and thickness.
    • 分裂弹头包括一个圆柱体和一个设在弹头的最内部的炸药。 在爆炸装置爆炸时,弹头主体最终被剪切并破碎成具有受控尺寸,形状的碎片。 弹头体的冶金组成可用于影响当弹头通过爆炸分解时最终产生的碎片的尺寸,因为弹头体中碎片的尺寸和位置是预选的。 本发明提供了具有复合形状和中小口径的预制碎片钨合金碎裂壳的爆炸性碎片弹药的制造。 根据本发明的实施例,制造开始于具有给定的全强度的“绿色”钨合金碎片丸,其包裹在绿色较低强度的基质合金中。 据说这种产品是绿色的,因为钨被很大程度上用于替代其他可能被认为更具毒性的金属,如铅。 接下来,在该过程中按压大部分绿色碎片和基质混合物所需的近似形状。 这最终是烧结。 根据本发明的一个实施方案,烧结过程将最终导致钨合金的预制片全部强度包覆在钨合金的低强度基体中,其大小适合所需的壳形和厚度。
