摘要：

To study the effect of attitude on the tapered tail projectile penetration into thin concrete target, the finite element code LS-DYNA was used to simulate the process, perforating thin concrete target by the tapered tail projectile of different half-cone angle with a certain initial oblique angle. The features of projectile attitude variation were analyzed. The rules of changes about obliquity, pitch and angular velocity of projectile after perforation were obtained. The simulation results indicate that both the yaw angle and the angular velocity are existed with the projectile, and the designed tapered tail can benefit the yaw angle and the angular velocity decrease so as to hold the trajectory stability when the projectile penetrates thin concrete target. ©, 2015, Beijing Institute of Technology.
