  • 7A04 aluminum alloy with high strength-to-density ratio has been extensively applied for armour material domain. The projectiles normal impacting 7A04 aluminum alloy plates with 10 mm thickness was conduct by light gas gun, where blunt and ogival steel rod projectiles were involved. The damage modes and penetration characteristics of the 7A04 aluminum alloy targets were obtained. The whole impact process and the residual velocity were obtained by the high-speed camera system. The comparison of the initial velocity versus residual velocity between blunt-projectile penetration events and ogival-projectile penetration events indicated that 7A04 aluminum alloy plates own stronger resistance ability to ogival projectile impact than that of blunt projectile.
