药型罩锥角对聚能杆式侵彻体成型的影响

聚能杆式侵彻体主要用来对付新型防护装甲和混凝土工事、武装直升机和大型水面舰艇等目标。本文就药型罩锥角对聚能杆式侵彻体成型的影响进行研究，根据射流形成理论分析得到了射流微元头尾速度比与药型罩锥角和压垮角之间的关系，并采用观察不同锥角的药型罩结构所形成的侵彻体，在远距离飞行下的断裂情况，来验证射流微元头尾速度比与药型罩锥角和压垮角的关系，实验结果表明射流微元头尾速度比随着压垮角的增大而增大，与理论分析吻合。

Influence on Formed Mechanism of Jetting Projectile Charge by Liner Angle

The cumulative rod penetrating body is chiefly used to destroy the new kind of defending armor, concrete structure, armed helicopter, and the large surface vessel, and so on. The influence on formed mechanism of cumulative rod penetrating body by liner angle is studied. The relation of ratio of head velocity and tail velocity with liner angle and collapse angle is obtained through sharp-charge theory analysis. The relation is validated through observing the cumulative rod penetrating bodies which are formed in different liner configuration and their rupturing state when they fly long distance. The test indicates that the ratio of head velocity and tail velocity increases along with the collapse angle and liner angle, which is consistent with the theoretical analysis.
