Constructive variants of warheads forming an axial flow of propagation of preformed elements have been designed. Tests have been carried out on experimental units with varying thickness of wall and shape of the barrier between the preformed elements and the bursting charge. Obtained results show the formation of a high-speed axial flow of a large amount of striking elements of one and the same type having sufficient kinetic energy to hit the targets. Thus, by changing the wall thickness and the barrier shape, it is possible to increase the effectiveness of the fragmentation action by 35-40 % and to provide coverage of a larger area of damage.
