In order to study the effect of cone angle of the liner on jetting projectile charge (JPC), AUTODYN simulation software is used to build the shaped charge model. Numerical simulation of the jetting projectile charge with the large angle between 90?-130? of the liner is performed. The jetting projectile charge molding with different liner angle at the same time and the same burst height is studied, and the penetration of the homogeneous target is analyzed under the condition that the burst height is 5 times of the charge diameter. Under the same diameter and height of shaped charge, the effect laws of cone angle of the liner on the jetting projectile charge molding parameters are proposed. The research also shows that the jetting projectile charge has better continuity, stability and penetration performance when the liner angle is 100?-110?. The results provide a reference for design and application of jetting projectile charge warhead.
