    Abstract
  • In order to improve the formation and penetration performance of multi-explosively formed projectiles (MEFP), we analyzed the influence of the charge cover (both its shape and wall thickness), the shell thickness, the explosive initiation modes as well as the fragments bracket on the projectiles formation effect and velocity by numerical simulation method.Based on our analysis, we proposed an integral MEFP warhead, and verified experimentally its formation process, scattered characteristics and penetration performance.The results show that the MEFP can form 17 jetting projectile charges (JPC), each with a good shape and stable flight direction.The calculated flying angle of the MEFP is 14.5°, which is well accord with the experimental result 14.8°.This MEFP warhead can effectively damage the 603 armor steel plate with a thickness of 12mm.
