A thin-walls projectile has been designed,and penetration depth of projectiles was evaluated by YOUNG Equation. Axial acceleration was evaluated by SAPLL. penetration process of projectile on penetrating concrete target was analysed by LS-DYNA. Mechanical Parameters of projectile material were studied by experiment. Penetration depth and structure intensity of projectile were examined by a series of experiments on penetrating concrete target on Ø130 mm gas-gun. A conclusion is obtained, projectile isn't destroyed during penetrating concrete target,and reinforced concrete that is 300 mm in thickness was penetrated through.
