    • Shaped charges that generate fan-like jets can produce slotted holes in rock formations. A shaped charge includes a case having on open front end, an external surface and a longitudinal axis, all transverse cross-sections of the case being bi-symmetric; an explosive material disposed in the case, the case including at least one opening extending from the external surface to the explosive material for initiation of the explosive material; and a liner disposed over the explosive material; wherein a pair of substantially identical longitudinal slots are formed on the external surface, the longitudinal slots being about 180 degrees apart.
    • 产生风扇式喷气机的成形装置可以在岩层中产生开槽孔。 成形电荷包括具有开放前端,外表面和纵向轴线的壳体,壳体的所有横向横截面是双对称的; 设置在壳体中的爆炸性材料,所述壳体包括从外表面延伸到爆炸材料的至少一个开口,用于引爆爆炸材料; 以及设置在爆炸材料上方的衬套; 其中在所述外表面上形成一对基本上相同的纵向狭槽,所述纵向狭缝间隔约180度。

    • 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。
