Research on the Characteristic of Projectile Fragments Dispersion Based on Fragment Warhead Design

Abstract Dispersion of fragments of projectiles is an important factor affecting the lethal efficiency of projectiles and one of the main objectives of optimal design of fragmented warheads. By using Taylor angle approximation, Shapiro formula and experimental measurement, the fragment dispersion characteristics are analyzed. The results show that if the mass of metal plate (fragments) detonated by explosive is constant, the characteristics of fragments scattering are basically determined; for a certain structure of shell warhead, the direction of fragments scattering is related to the initiation position and the direction of detonation wave propagation; and by marking the size of the dispersing sector, the range of fragments scattering can be determined.
