Abstract

Explosive bodies for use in hollow-charges are produced by casting a mixture of solid, particulate explosive material dispersed in melted explosive material. The sedimentation of solid explosive in melted explosive is carried out in an undisturbed manner in the mould, i.e. without being influenced by convection currents within the mixture or by collision with the walls of the mould, giving rotationally symmetrical explosive bodies. The detonation front deviation from nominal shape does not exceed 0.05 percent of the body diameter in case of rotationally symmetrical initiation of detonation of the produced explosive body.
