钛合金板抗12．7mm穿甲燃烧弹倾角效应试验研究

Obliquity effect of titanium alloy plates against 12.7 mm API

采用12.7 mm穿甲燃烧弹对水平厚为25.5 mm的Ti-6Al-4V钛合金板进行倾角效应试验,以研究钛合金板倾角对其防护能力的影响。采用等重钢总穿深的方法考核其抗弹性能。结果表明:钛合金板抗小口径枪弹(12.7 mm穿燃弹)倾角效应的基本规律呈现正效应,对于水平厚为25.5 mm的钛合金板,其跳弹角为62°。

Tests of obliquity effect of Ti-6AI-4V plates with a thickness of 25.5 mm were conducted using 12.7 mm piercing incendiary projectiles. Steel equivalent penetration depth was defined as the penetration resistance of Ti-6A1-4V plates. The results show that the obliquitY effect of Ti-6AI-4V plates is positive effect when penetrated by 12.7 mm API. For Ti-6AI-4V plates with the thickness of 25.5 mm, the ricochet angle is 62°.
