Design Techniques for Linear Fragment Distribution in Dynamic Explosion

摘要

Due to urgent needs for anti-missile technology in modern war, a so-called dynamic linear distribution fragment launcher is proposed in this paper, which could produce almost linear fragment perforations on target in dynamic explosion, accompany with tear effect around the perforations and stress concentration effect, thus producing efficient structural damage, similar to wire cutting, on target. Based on the design principle of this device, the design method and calculation formula of major parameter are given. And the validity and reliability of this design have proved by numerical simulation and prototype test.
