DEVICE FOR FORMATION OF DISTRIBUTED BLAST WAVE Russian patent published in 2018 - IPC F42B3/93 

FIELD: blasting operations.

SUBSTANCE: invention relates to the provision of explosions of areal charges from sheet explosive (EX) and can be used in the practice of strength testing of barriers: materials and structures, as well as for obtaining gradient construction materials with density (porosity) distributed over the layers and surface of the obstacle, corresponding to the profile of the formed blast wave. Device for forming a distributed blast wave consists of sections of an explosive and an initiation system. Perforated tapes of sheet explosive with a series of through holes are fixed on the tubes of circular cross section on the side of the barrier, staggered parallel to each other in a staggered manner in two rows and excluding collision detonation waves. Initiation system includes one electric detonator and detonation wiring located in the center of each strip.

EFFECT: technical result is aimed at expanding the range of creating small and ultra-small pressure pulses.
