Description

The invention relates to the field of weapons, in particular to munitions fuses.

A device is known that contains a sleeve with an explosive charge placed in it, made in the form of hinges: output from a high-density secondary explosive and an initiator coupled to an initiator mounted on a sealing block with current leads (AS No. 1746778 IPC F42C 19/12 , published on January 20, 1995).

Disadvantages: a low-density secondary explosive charge was used as an initiating explosive charge, which lengthens the convective combustion stage, increasing the response time of the electric detonator, and requires high-voltage initiation, which is caused by the use of an exploding bridge, the manufacture of which is technologically difficult.

A known device containing a sleeve with an explosive charge placed in it, made in the form of a hinge - an output from a high-density secondary explosive and an initiator coupled to an initiator mounted on a sealing block with current leads, equipped with a spark gap placed between the sealing block and current leads, and equipped with an insert installed in the sleeve with a charge of explosive and an intermediate sample of low-density deflagrating explosive, located th between the output and the initiating webs, while the initiating weigher is made of high-density deflagrating explosive with an axis height defined by the formula h = (22 .._ 26) D _AND , where D _AND is the initiator diameter (RF patent 2389971, IPC F42C 19/12, publ. 05.20.2010).

The specified device operates as follows.

When a subversive electrical impulse is supplied to the initiator, a hitch from a high-density deflagrating explosive is initiated and the following attachments are sequentially activated: intermediate, from a low-density deflagrating explosive, and the output from a high-density secondary explosive.

The main disadvantage is the need to use three attachments - initiating, intermediate and output, which leads to a complication of the design and manufacturing technology of the electric detonator.

The task to which the proposed technical solution is directed is to create a head fuse and a method for its use, which ensures high reliability of combat use and increased safety in official use.

The solution to this problem is achieved by the fact that the proposed head fuse according to the invention comprises a detonation command sensor, a power source, an electronic unit, a detonator, a safety-actuating mechanism, including a safety shutter, a transfer charge, an electric detonator, in which the explosive charge is installed, an initiator connected to the electronic unit, while the explosive charge of the electric detonator consists of two attachments: output, made of secondary high density explosive substance, and an initiating sample made of explosive diperchlorate (5-nitrotetrazolato) pentaamine cobalt (III), paired with an initiator, which is used as a semiconductor energy converting element, while the height of the initiating sample along the longitudinal axis of the charge is made from the condition of transition combustion of the initiating sample into detonation when a semiconductor energy-converting element is triggered.

To use the proposed head fuse, a method is proposed in which, according to the invention, a safety shutter, a transfer charge, an electric detonator, including a sleeve with an explosive charge and an initiator, are used as a low-voltage semiconductor energy converting element mounted on a device for the safety-actuating device terminal block with current leads; a charge of an explosive substance, consisting of two pieces, the output sample being made of high-density secondary explosive, and the initiating sample is made of explosive diperchlorate (5-nitrotetrazolato) pentaminecobalt (III), which is paired with a semiconductor energy-converting element, while the height of the initiating sample along the longitudinal axis of the charge, choose from the condition of ensuring the transition of the initiating sample to detonation upon operation of the semiconductor energy-converting element, after h it, when there are forces that ensure cocking of the safety-executive mechanism, mainly when fired, the safety shutter is put into working position, thereby closing the fire circuit of the electric detonator - transfer charge, after which an electrical impulse is applied to the current outputs of the electric detonator, thereby ensuring the operation of the semiconductor energy converting an element that activates the initiating hitch, the detonation pulse from which is transmitted to the output hitch and then along the firing chain and a detonator.

The invention is illustrated by drawings, in which Fig. 1 shows a diagram of a head fuse, Fig. 2 is a structural diagram of a safety-actuating mechanism in the initial position, Fig. 3 is a structural diagram of a safety-actuating mechanism in a combat position, Fig. 4 is a shows a cross section of an electric detonator.

The head fuse 1 includes a detonation command generation sensor 2, a power source 3, an electronic unit 4, a safety-actuator 5, a detonator 6. A safety shutter 8 with an intermediate charge 9, a transfer charge 10, an electric detonator are installed in the housing 7 of the safety-actuator 5. 11, consisting of a sleeve 12, containing an explosive charge of two hinges: an output hinge 13 made of a secondary explosive, and an initiating hinge 14 made of a diphlorate substance (5- itrotetrazolato) pentaaminkobalta (III), with pads 15 mounted thereon initiator - semiconductor energy conversion element 16 with current 17 connected to the electronic unit 4.

The proposed method and operation of the head fuse is as follows.

After the ammunition is fired, when the forces occur that ensure the safety-actuating mechanism is cocked, the safety shutter 8 is put into operation by connecting the fire circuit of the electric detonator 11 - detonator 6. When the sensor 2 generates detonation commands, the electronic unit 3 supplies an electric pulse to the current leads 17 of the electric detonator 11, the semiconductor energy converting element 16 is activated, which activates the initiating hinge 14. Then the detonation is transmitted to the output hinge 13 and then transfer mu charge 10, which activates the detonator 6.

The positive effect achieved during the implementation of the invention is expressed in increasing the safety of the head fuse in official circulation and ensuring reliability during combat use.
