大孔径深穿透射孔弹射流的X光片分析

X-ray Photo Analyzing for Jet of a Perforating Charge with Big-hole and Deep-penetration

通过对大孔径、深穿透射孔弹的X光片的分析,认为较高的射流圆盘速度对射孔弹提高射孔孔径以及穿透深度均有好处。在设计中应保证药型罩第2锥角与第1锥角的角度差在15°左右。三锥药型罩的第2锥的角度将直接决定第2段射流的速度分布,进而影响到射流圆盘的增长速度。试验得出,第2锥的角度选择在56°左右为宜。为以后进行多锥等特殊结构的药型罩的设计以及射流特性的研究起到了抛砖引玉的作用。

X-ray photograph analyses of jet flow produced by a perforating charge with big-hole and deep-penetration show that higher velocity of jet flow disc is beneficial to improve hole diameter and penetration depth of the charge.The difference between the 1st taper angle and the 2nd taper angle should be ensured to be about 15°.The angle of the 2nd taper in tri-cone charge will directly determine the distribution of jet velocity of the 2nd segment,and then influence the increasing of jet flow disc.The experiment...
