FIELD: fuses actuated by a preset mechanical force, applicable in development of the design of a detonating device of an impact mechanical fuse. ^ SUBSTANCE: the detonating device of a mechanical fuse has a body with a primer detonator, lead charge and a detonator made of a high explosive positioned in succession in it, the deformable component of inert material in the form of a disk and installed between the cylindrical striker and the primer detonator, which is linked with the lead charge through the axial duct of the body, the body is realized in the form of a bush and a sleeve fastened by a nut, whose end face surface is positioned above the end face surface of the striker, and radial holes filled with a low-melting alloy are made in the zone of a low-melting alloy are made in the zone of location of the lead charge, for fastening to the mechanical fuse made on the outer surface of the nut are a thread and longitudinal ducts, as well as radial holes in the upper and lower parts of the nut, besides, the cylindrical striker is hermetically fastened in the nut cavity with the aid of a heat-resistant adhesive, and a union nut is used for fixation of the detonator, the primer detonator has dimensions of fractions of heat-resistant high explosive of about 0.2 mm. ^ EFFECT: enhanced safety of perforator operation in extreme conditions for provision of a reliable transfer of the detonation impulse and guaranteed failure of detonation due to wetting and washing-away of explosive and provision of failure of operation of the mechanical fuse. ^ 1 dwg |
