A rod-shaped explosively formed penetrator warhead

In order to further improve the damage capacity of the multiple explosively formed penetrator (MEFP) warhead, we designed a rod-shaped and explosively formed penetrator warhead. We firstly investigated the formation process and scattering effect of the penetrator were investigated using numerical simulation, and presented a design of rod-shaped warhead penetrators based on the analysis of the influence of the warhead's outer linings on the penetrator's formation process. Then we fabricated two principal prototypes of the penetrator warhead, one with and the other without outer linings, and performed the static explosion experiments to find out about their damage effects. The results show that the average penetration depth on the 40 mm-thick-45 steel, 3 m apart from the detonation center by the warhead penetrators without outer linings, is 27 mm., while those with outer linings can completely penetrate the target. Moreover, the penetration results of the experiment and the simulation are consistent with each other, thereby concluding that our design can significantly improve the formation quality and the penetration power of the rod-shaped penetrators.
