CELL CHARGE OF SHEET EXPLOSIVE Russian patent published in 2015 - IPC F42B3/10 

FIELD: blasting operations.

SUBSTANCE: invention relates to the technique of explosion of array charge of sheet explosives (explosives) and may be used in the practice of testing the barriers, materials and fragments of constructions, as well as in a number of pulsed technological operations with use of explosion, such as connection and hardening or reinforcement of material layers. The charge consists of a thin layer of explosive applied to the surface of the barrier, the detonators, and the initiation system. To eliminate the "knife effect" the charge is divided into sectors made in the form of combs with gaps between them, which enables to eliminate the interaction of detonation waves coming from different points of initiation. The detonation wiring is made in the form of explosive strips of the same length, facing with the side ends to the barrier.

EFFECT: simplification of the initiation system by reducing the number of detonation strips when reproduction of the pulsed nature of the barrier loading.
