Abstract

In order to meet the demand of low collateral damage, a cross-shape built-in fragmentation directional warhead was invented, which can select different detonation modes according to the target orientation and then control the radial dispersion characteristics of the fragmentation, in which the formation of anti-personnel fragmentation in the target area to achieve directional damage, while in the non-target area to achieve low collateral damage. Numerical simulation was used to study the fragmentation driving process during the detonation of the directional warhead in two modes: adjacent two-point detonation and adjacent three-point detonation. The characteristic parameters such as fragment dispersion velocity and radial dispersion angle were given at each position. Then, two principle samples were prepared and ground static explosion tests were conducted. The fragment velocity and radial dispersion angle were measured through high-speed photography and the distribution characteristics of fragment perforation on the target plate. The accuracy of the simulation is verified by comparing with the numerical simulation results, based on which the fragmentation velocity correction formula is established by introducing the energy distribution angle, and the parameters of the formula are fitted and analyzed according to the simulation results. The results show that the radial dispersion angle of fragments in the directed killing zone is controlled within 145° and 65° under adjacent two-point initiation and adjacent three-point initiation modes respectively, and the proportion of fragments in this area reaches 50.4% and 43% of the total number, respectively. The fragment velocity shows a graded distribution between 535 and 770 m/s. The penetration rate of 1.5 mm thick Q235A steel plate reaches 94.4% and 84.6% respectively, which can achieve the destruction of light vehicle type targets, while the rest of the area is a low incidental safety zone. The calculation result of fragment velocity based on the energy distribution model is basically consistent with the simulation data. The research results can provide new design ideas to the development of low collateral damage warhead.
