Fragment shot-line model for air-defence warhead

In this paper, a shot-line model that describes the process of air-defence warhead explosion and the fragment dispersion was developed, in which natur al fragment warheads, controlled fragment warheads, performed fragment warh eads, multi-P-charge warheads. fragment focusing warheads and continuous ro d warheads were included. The shot-line model is applied to both static and real dynamic conditions. The air drag and the fragment tumbling that influ ences the impact velocity and the ballistic deviation of the fragment and t he penetration prediction in the terminal effectiveness analysis were consi dered.
