EXPLOSIVE DEVICE Russian patent published in 2015 - IPC F42B3/10 

FIELD: blasting operations.

SUBSTANCE: invention relates to the field of explosion engineering, containing discrete detonation wave generator (DDWG), and can be used in development of military ammunition, explosive devices for use in economic activities (engineering charges, mining operations, machine engineering, etc.) and scientific -research activities. In the explosive device containing the main explosive charge, DDWG in the form of a matrix of inert material with a network of channels and openings with a general receiving area filled with explosive and coated with a shell, the initiation source, initiating a general receiving area, DDWG comprises a layer of explosive at the side of the main charge. The shell made of heat resistant material comprises through openings covering the groups of openings in the matrix, and drainage channels connecting the openings located in a zone of pressing of DDWG by the elements of housing with a cavity of the structure having connection with the external environment. At that the following conditions are fulfilled: Q<6 g, Q/S_c<2.7 g/mm², wherein Q is explosive weight in the matrix, attributable to one opening in the shell, Q/S_c is cross-sectional area of the drainage channel. The shell of the explosive device is made of foam-polycarbonate having density of 0.7-0.8 g/cm³.

EFFECT: increase in fire and explosion safety of explosive devices with DDWG due to removal of gaseous decomposition products of explosives beyond DDWG.
