LOGICAL EXPLOSIVE DEVICE Russian patent published in 2021 - IPC F42B3/10 F42D1/04 

FIELD: logical explosive devices.

SUBSTANCE: invention relates to logical explosive devices, to devices that implement logical operations using an explosion, and can be used in explosive systems, which are subject to high safety requirements to protect detonation chains of detonation in case of accidental or unauthorized actions. The explosive logic device contains a blocking circuit, a blocking release chain, an input and an output made of a plastic explosive in the form of detonation rods. Detonation rods are located in the channels of the inert lining. The blocking circuit includes detonation rods inlet and outlet, located perpendicular to the plane of the lining, and detonation rods located in the plane of the lining and including sections with different lengths, made with the possibility of blocking or conducting a signal. The output is made in the form of a detonation rod, enclosed in a metal sleeve, and an adjoining detonation rod for connecting sections of different lengths. The blocking release chain is made of a receiving detonation rod, located perpendicular to the plane of the pad, and a detonation rod located on the reverse side of the pad, intersecting with one of the sections of the blocking circuit.

EFFECT: reduction of the length of the dangerous section, the undermining of which leads to the activation of the main charge, as well as the possibility of placing all elements of the explosive logic device in the dimensions of one inert pad.
