Abstract

The ballistic trajectories of projectiles with differently shaped noses and composite material noses obliquely penetrating into steel target are researched. The deflection torque during the penetration is also studied. The results show that the ballistic deflection ofprojectile with truncated-oval nose is smaller, its performance against the ballistic degradation is high and its penetration trajectory is stable. The nose made of high-density and high hardness tungsten composite material shows the better penetration performance and the smaller ballistic deflection angle. The deflection relevance of oblique penetration ballistic trajectory is obtained based on the relation between the oblique torque and the oblique angle. It can be seen from orthogonal experiment simulation that the shape of the nose, the material of the nose and the penetrating velocity have the effects on the oblique angle.
