The purpose of the research is to develop a jet-type multimode warhead with penetration depth higher than EFP warhead's. The shaped charge with a right angle liner copper could form jet penetrator or the rod projectile with great difference of length-diameter ratio by adjusting initiation mode and burst height. The experiment results indicate that the rod projectile makes large but shallow perforation under the condition of single point initiation and productive burst height, the jet penetrator makes small but deep perforation under the condition of the annular initiation and beneficial burst height. Not only the penetration ability of two shaped charge penetrators is distinct, but also the warhead produces multipurpose damage of the fragments.
