• Ballistic trajectory
• Concrete target
• High velocity
• Oblique penetration

The experiments of small scale projectile obliquely penetrating a semi-infinite concrete target with a velocity from 980 to 1 870 m/s are performed by a two-stage light gas gun. The ballistic trajectory and characteristic parameters are tested and painted. The results show that the trajectory deflection of the penetrator obliquely penetrating a semi-infinite concrete target with high velocity is more obvious than that with intermediate and low velocities, and presents a shape of "J". The penetration process can be divided into four phases according to the penetration mechanism. In addition, it is found that the terminal gesture of the projectile changes greatly, and the deflection angle at endpoint can reach up to 130°.
