Abstract:
A warhead of rod-shaped circumferential multiple explosively formed penetrator(MEFP)is designed to improve the damage ability.The initial velocity of a new MEFP is researched using engineering calculation and numerical simulation.A static detonation experiment of the warhead prototype is done.The engineering calculation is adjusted according to the experimental result.The rod-shaped penetrator of a 127 mm rod-shaped circumferential MEFP warhead prototype can penetrate 40mm depth Q235 steel laid 3 m from the explosion center.The large length to diameter ratio of the rod-shaped penetrator is 4:1,which can satisfy the damage requirement.
