【Abstract】 In this dissertation,a model EPW is designed on the basis of theoretical analyses.Shell material and parameters of a projectile body,such as slenderness ratio and CRH(caliber radius head),were studied. Strength check and aerodynamic properties of a projectile body were investigated.The experimental examination of a projectile on penetrating semi-infinite concrete medium was performed.The values from theoretical prediction have good coincidence with the experimental data.Young equation can be applied to estimate the penetration depth.更多还原
