Opis:: Research of HE warheads lethal zone is very complex topic because of large number of controlled and independent, sometimes correlated, influencing factors. Capability for prediction of lethal zone is based on complexity of databases regarding natural fragmentation parameters, which should contain data about warhead body material characteristics, types of explosive charge, number, mass, initial velocity and spatial distribution of fragments, battlefield terrain, distribution of soldiers on battlefield, etc. Based on experimental research (fragmentation test in Arena facilities with two types of artillery projectiles and two types of rocket warheads), analytical and numerical methods used - projectiles lethal zones are predicted and analyzed. Influence of projectile design and explosive charges on warhead lethal zone is analyzed.

Opis:: In this article, the authors present a design methodology for generating a spatially tailored fragment beam with specified velocity and projection angles. The modified Gurney equation was used to estimate the length and diameter of the cylindrical charge to achieve the desired velocity; and the modified Taylor equation was used to arrive at the radius of curvature of the fragmenting disc. The methodology is further explained for generating a rectangular beam of fragments having a velocity of 1500 m/s with a tailored fragment beam of 32° in the azimuth and 20° in the elevation. The warhead had preformed steel fragments of 4 mm diameter arranged in a double layer. The design was validated using the fragment distribution measured experimentally.
