Abstract

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to armaments, particularly, to fuses. This head fuse comprises blasting instruction generator, power supply, electronic unit, exploder, safety protective mechanism including electric exploder with the case accommodating explosive charge and initiator connected with electronic unit. Explosive charge of electric exploder consists of two weights: outlet weight composed by secondary high-density explosive and initiating weight composed of explosive of diperchlorate (5-nitrotetrazolato) penta amincobalt (III) bonded with initiator. Note here that initiating weight height in the charge lengthwise axis is selected to allow changeover of initiating weight combustion into detonation at exploder initiator.

EFFECT: higher reliability and safety.

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 device is known that contains a sleeve with an explosive charge placed in it, made in the form of hinges - the outlet from a high-density secondary explosive and initiating, paired with 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 a liner installed in the sleeve with an explosive charge and an intermediate sample of low-density deflagrating explosive located m forward output and initiating weighed, the weighed initiating deflagrating made of high density with axial height explosive determined by the formula h = (22 26 .._) D _and where D _and - initiator diameter (RF Patent No. 2389971, IPC F42C 19 / 12, published on 05/20/2010 - prototype).

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 that provides high reliability of combat use and increased safety in official use.

The solution to this problem is achieved by the fact that in the proposed head fuse, including a detonation command generation sensor, a power source, an electronic unit, a detonator, a safety-actuating mechanism comprising an electric detonator, according to the invention, an explosive charge in an electric detonator consists of two attachments: output, made from a high-density secondary explosive, and an initiating sample made from dipherchlorate (5-nitrotetrazolato) pentamine-cobalt (III), coupled with and itsiatorom, which is applied as semiconductor energy conversion element. The height of the initiating hinge along the longitudinal axis of the charge is made from the condition of ensuring the transition of combustion that occurs when the initiator / semiconductor energy-converting element is triggered to detonation.

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 11 is installed in the housing 7 of the safety-actuator. consisting of a sleeve 12 containing a charge of an explosive from two hinges: an output hitch 13 made of a secondary explosive, and an initiating hitch 14 made of a diphlorate substance (5-n trotetrazolato) pentaaminkobalta (III), the initiator 15 at block 16 with current 17 connected to the electronic unit 4.

The operation of the head fuse is as follows.

After a shot of ammunition, when there are forces that ensure that the safety-actuating mechanism is cocked, the safety shutter 8 is put into operation, closing the firing circuit of the 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 detonator 11 , a semiconductor energy converting element 15 is activated, which activates the initiating hinge 14. Then, detonation is transmitted to the output hinge 13 from the secondary explosion atogo substance and further the transfer 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.
