Description

The present invention relates to ammunition for small arms.

A well-known cartridge with an electric capsule for firing a barrel with a traumatic action bullet (RU 2179700, F42B 5/073, 02/20/2002) containing an electric capsule and a propellant charge placed in the body of the gas generator, which is pressed into the sleeve. A traumatic bullet was rolled into the body of the gas generator. The cartridge is triggered when the electrocapsule is activated from an external switching current source.

The disadvantage of this device is the inability to use several bullets in one sleeve with the possibility of alternating throwing independent from each other.

As a prototype, a barrel set with shells placed on its axis was selected, which is a barrel with which the projectile heads are in electrical contact. A core block with a conical portion of the mandrel partially insulated from the projectile head partially passes through the projectile head. The core blocks abut against each other, as a result of which an electric circuit of superimposed core blocks is formed. In the head part, the core has a spring contact for electrical contact with the core of the next projectile. Next to it is a fixed contact, insulated from the core block and the projectile head. It is connected via an output to one side of the electric valve, which is also connected via the other output to the electrically conductive head of the projectile. The contacts are separated from each other by means of a fuse to isolate the electrical impulse to the forward projectile. After the firing of the front projectile, the fuse of the rear projectile fuses and closes the head contacts. (AU 96/00459, F42B 05/03, 07/10/96).

The disadvantage of this design is its complexity and complexity in industrial production.

The objective of the present invention is to reduce the complexity of the design and the complexity of its industrial production.

This technical solution is intended for sequential electric ignition of a propellant of ammunition located sequentially one after another in the barrel channel or sleeve.

The problem is solved in that the munition with electric ignition contains a conductive casing made electrically insulated from the barrel bore and with the possibility of supplying a polarity opposite to that supplied to the barrel, a conductive core electrically insulated from the casing and made with a conductive spring contact or a spring-loaded conductive element which are made with the possibility of contacting with the barrel, an electrocapsule connected to a conductive core and a conductive body the munition mustache through the current-carrying case of the gas generator inserted into the current-carrying case of the munition and compressed with a decrease in diameter in the rear part, while the body of the gas generator is configured to protect the propellant and the electrocapsule from external influences and create conditions for its proper ignition.

According to another embodiment of the invention, the electrically ignited ammunition comprises a conductive housing configured to be in electrical contact with the barrel, a conductive core located in front of the munition, electrically insulated from the housing, and a locking electrode electrically insulated from the housing and from the conductive core, an electrocapsule and a control unit located in the munition housing and connected to the control electrode.

In these ammunition in their rear parts may be located conductive washer with one or more holes.

The firing device for these munitions contains a conductive barrel, in the breech of which there is a removable conductive rod, electrically insulated from the barrel, and a cover worn on the muzzle of the barrel, with a part that enters the barrel, which, by configuration, repeats the rear of the ammunition. As a result, a shot is possible only when removing the cover.

The conductive rod can be located in the part covering the breech of the barrel, and is electrically insulated from it.

The essence of the invention is the creation of ammunition for multiply charged compact firing devices with a simple propellant ignition system.

The proposed technical solution can also be used to create a munition of traumatic action.

The proposed ammunition can conditionally be divided into two groups. Common to them is the presence in the design of the conductive shell of the ammunition and the conductive core located on the same axis as it is, insulated from each other.

These and other features of the invention, as well as the possibilities of its practical implementation will be more clear from the following detailed description, given with reference to the drawings, which show typical embodiments of the present invention.

The drawings do not show an external current pulse control unit.

Consider the ammunition of the first group. Their main feature is that the munition conductor body is separated from the barrel by an electrically insulating sheath and forms one branch of the electrical circuit, and the conductive core, electrically insulated from the conductive body, with its current-carrying spring contacts or spring-loaded conductive elements, electrically contacting the barrel, forms the second branch of the electric circuit. Figure 1 shows the ammunition installed in the barrel 1, it consists of a conductive shell of ammunition 2 with an electrically insulating sheath 3, a conductive core of ammunition 4 with conductive spring contacts 5, an electrically insulating layer 6, a conductive body of a gas generator 7, in which there is an electrocapsule 8 and a propellant substance (not shown). The conductive body of the gas generator 7 is inserted into the conductive body of the munition 2, and the back of the conductive body of the gas generator is compressed with a decrease in diameter. The electronic capsule 8 is connected to the conductive core and the conductive shell of the munition through the conductive body of the gas generator. For the conductive spring contacts on the outer side of the conductive core and the front of the conductive shell of the munition grooves 9 are made, which fully contacts the conductive spring contact 5 when preloading.

The ammunition operates as follows: the conductive spring contact of the conductive core, if it is not pressed in, which occurs when it is abutted against the rear of the forward ammunition, enters into electrical contact with the inside of the barrel, through which current is supplied with the polarity opposite to that passing through the conductive shells of the ammunition . When an electrical pulse is supplied, an electrocapsule is triggered, which is connected to the conductive shell of the munition through the conductive body of the gas generator on one side and with the conductive core on the other. An electrocapsule ignites a propellant, which, when burned, creating a certain pressure, opens the back of the ammunition, after which the gases burst into the bore and expel the ammunition.

Figure 2 shows the ammunition ready to be fired — turned on, and the ammunition with a spring-loaded spring contact, i.e. disconnected.

The ammunition shown in FIG. 3 is similar to that shown in FIG. 1, except that the conductive core 4 protrudes in front of the conductive body 2 and enters the hollow rear portion in front of the ammunition in front. For the conductive spring contacts on the outside of the conductive core and the front of the conductive shell of the munition grooves are made, which fully enters when the conductive spring contact is pressed.

Figure 4 shows the ammunition ready for firing, i.e. included, and ammunition with a spring-loaded spring contact, i.e. disconnected.

Next, consider the ammunition of the second group.

Its difference from the ammunition of the first group, discussed above, is that it is in electrical contact with the barrel directly with its conductive body, and the conductive body of the gas generator, like the conductive core, is electrically insulated from the shell of the munition. A locking electrode is also electrically insulated from the conductive housing.

In Fig. 5, it consists of a conductive case 2, a charge in the conductive case of a gas generator 7, electrically insulated from an ammunition conductive body by an electrically insulating layer 6, an electrocapsule (EC) 8 and an ammunition control unit (BUB) 17. A conductive core (TC) is located on the front of the munition ) 4, electrically insulated from the conductive case, and a locking electrode (ZE) 15, electrically insulated from the conductive shell of the munition and the conductive core with a layer 16.

The current is transferred to the ammunition for the electrocapsule 8 through their conductive bodies 2 from the barrel 1 and sequentially through the conductive core 4 of each ammunition in a row (Fig.6).

Inside the ammunition is placed BUB17, to which ZE15 is connected. Each subsequent ammunition closes the earth element on its current-carrying case, thereby blocking the EC operation through the BUB. When an electrical pulse is applied to a series of ammunition, only one unblocked EC of the last in the series of ammunition is triggered.

Figure 6 shows the connection diagram of the munition control unit.

Figure 7 shows the ammunition of the third group, characterized in (Fig. 5) that the locking electrode 15 is closed not on the conductive case of the ammunition, but on its conductive core.

On Fig shows a modified (in Fig.5) ammunition with a conductive washer 18 in the rear of the ammunition. The washer is electrically insulated from the conductive shell 2 of the munition, is conductive for the conductive body of the gas generator 7 and the conductive core 4 of the next ammunition.

Holes or holes in the form of a jet nozzle are made in the washer 18. In this case, the ammunition uses jet propulsion for its movement.

Either holes or a hole are made in the washer, allowing the ammunition to disperse according to the principle of high - low pressure.

This variant with a washer is acceptable for all of the ammunition described above, with the only difference being that, depending on the particular design of the ammunition, the washer can be conductive to the conductive case and electrically insulated from the core.

Figure 9 shows a firing device for the ammunition described above, charged through a muzzle. It consists of a barrel 1, in the breech of which is a removable conductive rod 19, insulated from the barrel by a layer 20.

In this embodiment, the conductive rod 19 as well as ammunition enters its seat through the muzzle of the barrel. This solution facilitates the care of the barrel, and also allows you to defuse the barrel if necessary.

Figure 10 shows a firing device that is charged from the breech.

In this embodiment, the current-transmitting rod 19 is located in the part 22, which locks the breech of the barrel, and is electrically insulated from it by a layer 20.

A fuse cover 21 is put on the muzzle part of the barrel. The part of the cover that enters the barrel channel repeats the configuration of the rear part of the ammunition. Thanks to this solution, the firing device cannot be fired until the cover is removed. The cover can be made as dressing (screwing) on the barrel, and hinged.
