钨合金易碎穿甲弹对柴油的引燃特性

Ignition Characteristics of Fragile Tungsten Alloy Penetrator Acting on Diesel Fuel

为研究着靶速度、着靶角度、靶板厚度和弹体截面形状对易碎穿甲弹引燃特性的影响,在对易碎穿甲弹引燃特性分析的基础上,开展了不同条件下钨合金易碎穿甲弹对0号柴油的穿甲引燃实验。结果表明:弹体的引燃特性随着着靶速度的增加而提高;在一定范围内,靶板厚度的增大有利于提高弹体的引燃特性,但是随着靶板厚度的进一步增大,弹体的引燃特性减弱;在不同着靶速度和着靶角度下,三角形截面易碎穿甲弹较等截面面积和弹长的圆形截面易碎穿甲弹有更好的引燃特性。

Based on the analysis of the ignition characteristics of the fragile penetrator, the ignition experiments for No. 0 diesel fuel were carried out to investigate the influence of the incident velocity, the incident angle,and the cross-section shape of the projectile and the thickness of the target on the ignition characteristics of the fragile tungsten alloy projectile. The results show that the ignition char- acteristic is improved with the increase of the incident velocity~ to a certain degree, the ignition charac- teristic is improved with the increase of the target thickness,and then weakened with the further in- crease of the target thickness ; the fragile projectile with a triangular cross-section has a better ignition characteristic than that with a circular cross-section at different incident velocities and incident angles.
