EXPLOSIVE APPARATUS Russian patent published in 2021 - IPC F42C19/10 

FIELD: explosives.

SUBSTANCE: invention relates to detonating apparatuses triggered on impact of a predetermined mechanical force, can be used in developing a design of a mechanical detonating fuze and in detonation circuits of automatic explosive equipment. The explosive apparatus consists of a body 1 in form of a sleeve with a detonator and a primer detonator located therein. The detonator is installed at the bottom of the sleeve. The primer detonator made in form of a metal dividing element in form of a cap with an initiator of a secondary explosive substance (explosive) is located on the detonator. The initiator is attached in the cap by a fixing element. The detonator is made in form of output and transfer charges coupled with the primer detonator. The transfer charge of the detonator is made of a secondary explosive. The output charge is made of a secondary explosive. The height of the initiator along the axis is determined by the ratio: h_i ≥ 2H_cr, wherein H_cr is the critical thickness of the initiator layer of a secondary explosive. The cap is made of steel. The fixing element is made of foil.

EFFECT: invention allows improving operational characteristics of the explosive apparatus, namely, reduce the actuation power, increasing safety during manufacture and operation by eliminating the use of highly sensitive initiating explosives, increasing the output power of the explosive apparatus with small dimensions.
