Abstract

Abstract: A new asymmetrical initiation multiple explosively formed penetrator（MEFP） warhead is designed to improve the damage efficiency of MEFP warhead. Two principle prototypes with central initiation and eccentric initiation were made for static detonation experiment. The forming and dispersing processes of MEFP with hemispherical liners under different ways of initiation are analyzed through numerical simulation. The numerically simulated results illustrate that the length-diameter ratio of EFP is larger, and the EFP is more dense in two-point eccentric initiation mode. The static detonation experimental results of MEFP warheads in two different initiation modes are compared. The comparative results show that the ecentric initiation can is used to improve the velocity, density distribution and penetration power of EFP. The two-point eccentric initiation can effectively improve the comprehensive damage effectiveness of MEFP warhead. Key
