间隔靶对射流侵彻能力影响极限的实验研究

Experimental Study on the Ultimate Adverse Effect of the Space between Target Plates on Jet Penetration Depth

利用实验方法对间隔靶影响射流侵彻能力的极限值进行了确定。通过实验,获得间隔靶间隔值与射流侵彻深度的关系曲线,得出间隔靶对射流侵彻能力的降低极限为5.5%左右,即当间隔靶间隔值为最不利于射流侵彻的间隔值时,每个间隙使射流的侵彻能力下降5.5%左右。通过对实验现象的观察,发现射流在间隔靶之间的飞溅是降低射流侵彻能力的一个主要因素。

A relative curve of jet penetration depth vs the space between target plates and the ultimate adverse effect of disconnected target on the depth were determined by this experimental study. At every layer of disconnected target, the penetration depth of jet would be reduced about 5.5% when the space between target plates was the ultimate adverse value for jet penetrating. The phenomenon of experiments showed that the splash of jet between target plates is an important adverse factor for jet penetrating into disconnected target.
