For research influence of projectile head shape on penetration performance, research penetration of different projectile head shape on concrete. Design flat projectiles and ogive-nose projectiles, based on DOP to carry out test comparison analysis. The results show that the ogive-nose projectiles have better penetration performance. The hole of stability penetration is straight, the structure of projectiles are good. The head of the ogive-nose projectile is more pointed, the penetration performance is better. This study can provide some help for the structure design of projectile.
