长杆弹垂直侵彻有限厚靶攻角对弹道极限速度影响的研究

研究了长杆弹垂直侵彻有限厚靶时，着靶攻角对侵彻行为和终点效应的影响。定理分析了不同着速、长径比和弹材密度情况下，攻角对弹道极限速度的影响规律。并就某模拟弹等进行了理论计算和实验验证，结果令人满意。用本文建立的模型还可计算弹丸穿透靶板后的剩余速度，剩余弹长，剩余质量和塞块的厚度等。

EFFECTS OF THE ANGLE OF ATTACK FOR A LONG ROD WHEN PERFORATING NORMALLY THROUGH F INITE THICKNESS TARGETS AT BALLISTIC LIMIT VELOCITY

Influence of the attitude of a long rod penetrator when striking a finite thickness target normally upon the impact process and terminal effects is described.The influence of the angle of attack on the Ballistic Limit Velocity with various striking velocities,ratios of length to diameter and densities of the projectile and target materials are also studied.Calculations for the projectile of a smooth-bore gun are given and verified experimentally.The results prove to be satisfactory.With this model,the resi-dual velocity,rod length,and mass of the projectile and the mass and thickness of the plug after penetration can be computed.
