FIELD OF TECHNOLOGY

The invention relates to weapons with electric weapons.

BACKGROUND

Patent Application WO2009252575 describes a multiple-charge remote stun device using a twin shot based on unitary cartridges located in a removable magazine that is inserted into the device. In the dielectric casing of the unitary cartridge are located the projectile, pyrotechnic source and current-carrying elements. The projectile consists of a head and tail parts (a probe and a pallet) that are separated when fired and connected by a conductor placed in the inner cavity of the probe. The shot is carried out by simultaneously moving a pair of unitary cartridges to the position of the shot. Cartridges are moved from the magazine to the firing position by a bolt placed in the magazine, connected through a system of levers with a start key controlled by the muscular effort of the shooter. When the cartridges are moved to the firing position, the electrical circuit of the device is launched and high voltage is applied to the lead-in electrodes of the cartridges. When high voltage is applied, a spark discharge initiates pyrotechnic cartridge sources. Under the influence of the pressure of the combustion products of the pyrotechnic composition, the shells are accelerated in the channels of the cartridges. On the final acceleration section, the probe and the pallet are separated as a result of the braking of the pallet in the muzzle of the cartridge. After separation from the pan, the probe with the attached end of the coil of the conductor located in the inner cavity of the probe flies to the target, and the pallet connected to the other end of the coil stops in the muzzle of the cartridge. The pallets stopped in the muzzle narrowing are electrically connected to the current-carrying electrodes of the cartridges, to which a high voltage of the electric discharge is transmitted through the body of the object when the discharge circuit is closed after the probes enter the body of the object.

When the shooter releases the device’s start key, the shot cartridges with wires attached to them are ejected from the device. To re-shoot the arrow, press the start button again.

The disadvantage of this device is the large stroke of the key and the significant effort required to move the cartridges to the position of the shot, which negatively affects the accuracy of the shot. Another disadvantage of this device is the manual extraction of the shot cartridges, which occurs when the shooter releases the trigger key. If the shooter releases the key immediately after the shot, for example intuitively, as when firing from a conventional pistol, or under the influence of recoil, the cartridges will be immediately extracted and the duration of the electric discharge through the body of the object will be insufficient to effectively influence the object.

After separation from the pallet, the probe moves in the muzzle narrowing channel, which provides the initial orientation of the direction of motion of the probe during firing. Thus, the length of the section on which stabilization of the probe’s movement is limited by the dimensions of the cartridge, which negatively affects the accuracy of the shot.

The length of the projectile acceleration section in the unitary cartridge is also limited by the dimensions of the cartridge. Since the cartridge housing is made of plastic, insufficient housing strength and cartridge dimensions limit the energy of the probes and, accordingly, the range of the shot.

In the specified device for transmitting an electric discharge through the body of the object, it is necessary that the probes are fixed on the body of the object. For this, the probes have an element of fixation on the target, made in the form of a needle with a hook. The presence of probes with a needle with a hook significantly increases the possibility of injury, for example, when a probe needle enters the blood artery.

The prototype of the present invention is selected described in patent application RU 2001126612 remote stun device using a twin shot based on a unitary projectile. In the prototype, unitary shells are located in a removable magazine that is inserted into the device. A unitary projectile consists of a head and tail parts (probe and pallet) that are separated when fired and connected by a conductor placed in the internal cavity of the probe. To accelerate unitary shells, the energy of a pre-charged spring is used. The acceleration of unitary shells is carried out in separate guiding dielectric channels using a dielectric carriage connected to a spring. The guiding dielectric channels have output windows in which the projectile is separated when fired. The probe with the attached end of the coil of the conductor located in the inner cavity of the probe is separated from the pallet and flies to the target, and the pallet connected to the other end of the coil stops in the output window of the guide dielectric channel. The pallets stopped in the exit windows are electrically connected to the current-carrying electrodes of the device, to which a high voltage of an electric discharge is transmitted through the object’s body when the discharge circuit is closed after the probes enter the object’s body.

The extraction of pallets fired shells in the described device is carried out by re-cocking the spring. In this case, the spring-loaded carriage holding the pallets in the device after firing releases the pallets, and the pallets are ejected from the device by the elastic levers of the ejectors cocked when the carriage moves.

The disadvantage of the prototype is the low practical rate of fire, as well as the great mechanical force that the shooter must exert to cock the spring. The disadvantage of the prototype is also the low coefficient of energy conversion, since the energy of the compressed spring is additionally spent on accelerating the carriage, which pushes the accelerated shells. At the moment the pallets stop in the output windows of the device, the pallets, carriage and the supporting surfaces of the output windows of the guide channels experience a high shock load. Periodically acting high impact load can lead to deformation or destruction of the elements of the device, which negatively affects the reliability of the device and reduces the working life.

SUMMARY OF THE INVENTION

The aim of the invention is to increase the rate of fire, reliability of operation and accuracy of the shot of weapons with electric weapons.

The device according to the present invention uses a twin shot based on unitary shells. Unitary shells are located in a removable magazine, which is inserted into the device. When firing, unitary shells are moved from the store to the device’s metal trunks by dielectric shutters. As a magazine, for example, a box magazine can be used, which has two exits for moving shells into the corresponding barrel. Metal trunks are placed in the dielectric frame of the device. The case of the dielectric frame isolates the metal trunks from the conductive elements of the device, which are not current-carrying elements of the discharge circuit, providing current transmission through the body of the object, and thereby exclude the possibility of spurious discharge bypassing the discharge circuit.

The unitary projectiles used in the device consist of a probe and a pallet that are shared when fired, interconnected by a conductor placed in the internal cavity of the probe. The unit shell tray is made of an elastic dielectric material, for example polyurethane. At the end of the dielectric tray is a metal capsule cap filled with a pyrotechnic composition, and the inner cavity of the cap is connected to the inner cavity of the probe by a gas channel. An electrode is arranged in the dielectric tray, which is electrically connected to the probe’s metal case and is intended to initiate a pyrotechnic composition by a spark discharge, which passes through the pyrotechnic composition when voltage is applied between the metal capsule cap and the metal case of the probe.

The initiation of a shot is carried out after the shells are moved by dielectric bolts from the magazine into metal barrels and are at the position of the shot. When the shot is initiated, the pyrotechnic composition of the capsule is ignited, and the combustion products pass through the gas channel of the pallet into the internal cavity of the probe. Under the influence of the pressure of the combustion products, the probe is separated from the pallet and the probe is accelerated in the metal barrel. After acceleration in the barrel, the probe flies to the target. The probe and the tray are connected by a metal conductor, packed in the inner cavity of the probe in the form of a coil, which opens from the cavity during the flight of the probe.

After hitting probes simultaneously launched from both device trunks, the electric discharge circuit closes through the body of the object.

To defeat an object, a single high-voltage pulse or a series of successive high-voltage pulses can be used. A single pulse can be obtained by using a high-voltage capacitor connected to current-carrying elements of the discharge circuit. A series of high voltage pulses can be obtained by using a high voltage transformer connected to current-carrying elements of the discharge circuit.

After the electric discharge is transmitted through the body of the object for the subsequent shot, the pallets of the shot shells are extracted from the trunks. The extraction of the pallet of each of the shells is carried out through the barrel by pushing the pallet with a dielectric shutter rod that is moved in the barrel channel. Extraction of pallets of shot shells after launching the probes is carried out with a time delay, which ensures the delivery of a striking electric discharge to the target. In order to ensure the passage of a single discharge or a series of successive discharges through the body of an object, the extraction of pallets connected through the corresponding conductors with the corresponding probes should not occur before the probes reach the target, and a discharge will pass through the body of the object. Thus, in the general case, the time delay for the extraction of pallets after launching the probes should be greater than the sum of the time the probe flies to the target at the maximum distance of the shot and the discharge passage time.

For example, for a maximum shot distance of 10 meters and an average flight speed of the probes of 100 m / s, the maximum flight time of the probe to the target will be 0.1 seconds.

If a single pulse of a high voltage capacitor is used to hit a target, the electric discharge of the capacitor through the body of the object takes place in a time substantially less than 0.1 second. For example, with a capacitance of a high-voltage capacitor of 1000 pF and a discharge circuit resistance of 1000 Ohms, the characteristic capacitor discharge time is several microseconds. Thus, the extraction delay time using a single discharge of the capacitor is determined mainly by the probe’s flight time to the target and should be slightly more than 0.1 seconds.

When using a discharge in the form of a series of consecutive pulses, the required extraction delay time will be determined by the time of flight of the probes to the target and the duration of the discharge. For example, with a discharge duration of 0.5 seconds and a maximum flight time of the probe to the target of 0.1 second, the extraction delay time should be slightly more than 0.6 seconds.

After extraction of the pallets of the fired shells, the gates return to their original position, and the shot / extraction cycle can be repeated. An electromechanical actuator, for example, based on a gear motor and a rack and pinion gear, is used to move the shutters.

General control of the electronic circuit of the device is carried out by an electronic unit based on a microprocessor. When using microprocessor logic, a control algorithm can be implemented in which the shot / extraction cycle is carried out in semi-automatic or automatic mode by pressing the start key associated with the microswitch that launches the electronic control unit. To select a semi-automatic or automatic firing mode, a fire mode translator can be used, the position of which determines the control algorithm.

The use of an electromechanical shutter drive in the device according to the present invention allows for a small stroke and a small force associated with the electronic trigger switch, by pressing which a shot is fired. Small stroke and low effort on the start key allows you to increase the accuracy of the shot.

The use of an electromechanical shutter drive also allows you to increase the rate of fire of the device, since the projectiles are sent to the firing position and the pallets are extracted automatically. In addition, the automatic extraction of pallets eliminates the possibility of premature discharge interruption, as in the case of manual extraction, which increases the reliability of the device.

Known remote electroshock devices, for example TASER®, which use an electric discharge in the form of a series of consecutive pulses to hit an object, use probes, each of which is equipped with a locking element on the target, which is made in the form of a needle with a hook. Remote stun device according to the present invention, using to discharge the target discharge of a high voltage capacitor, allows the use of probes without elements of fixation on the target. The absence of fixation elements allows to reduce the likelihood of injury associated with the penetration of the fixation element into the body of the object, for example, when the needle penetrates the blood artery.

Unlike the prototype, in which the separation of the projectile occurs when the pallet hits the abutment surface of the output window of the device, the separation of the projectile when fired in the device according to the present invention occurs in a metal barrel under the influence of the pressure of the combustion products of the pyrotechnic composition. The absence of colliding elements that can lead to their destruction, and the high mechanical strength of the metal barrel can increase the reliability and service life of the device according to the present invention.

DETAILED DESCRIPTION OF THE INVENTION

In more detail, the construction and principle of operation of a remote stun device based on a unitary projectile in accordance with various aspects of the present invention will be described below based on the presented drawings.

Figure 1 shows a General view of a device using a high-voltage capacitor discharge to hit a target. The dielectric frame 1 of the device houses a dielectric frame 2, an electromechanical drive based on gear motors 3, an electric battery 4, an electronic board 5, a microprocessor 6, which controls the electronic circuit of the device, a high-voltage constant-voltage generator 7, a high-voltage capacitor 8, and a start key 9 connected with micro switch 10, which starts the microprocessor.

The dielectric frame 2 has a compartment, which houses a removable magazine 11 with unitary shells. The dielectric frame 2 has front protrusions 12 with dielectric channels 13 through which the unitary projectiles are sent to the shot position in the metal barrels 14. The dielectric frame 2 also has rear protrusions 15 in which the dielectric gates 16 are placed. On the dielectric shutter body 16 there is a profile in the form gear rack. The teeth of the toothed rack of the gates are engaged with the teeth of the gears 17 fixed to the shaft of the corresponding gear motor 3. The terminals 18 of the DC high voltage generator 7 are connected to the electrodes 19, which are brought into the internal cavity of the dielectric channels 13. The terminals 20 of the high voltage capacitor 8 are connected to electrodes 21, which are in electrical contact with metal trunks 14.

Figure 2 shows the store 11 with unitary shells 22 without elements of fixation on the target. The store has two compartments, in each of which shells 22 are located, as well as a projectile feeder and a spring (in Fig. 2, the feeder and the feeder spring are not shown), designed to supply shells to the corresponding outlet of the store. To fix the magazine, an elastic latch 23 is used, which, when the magazine is installed in the device, is fixed by engagement with a corresponding recess in the device case.

Figure 3 shows the magazine 11 with unitary shells 22 having an element of fixation on the target 24.

Figure 4 shows a section of a unitary projectile without an element of fixation on the target. The metal probe 25 has an internal cavity in which the coil 26 of the metal conductor 26 is placed. One end of the coil is attached to the probe, for example, using a conductive adhesive connection 27, and the second end of the coil is attached to the electrode 28, for example, by soldering. The metal electrode 28 is placed in a dielectric tray 29 made of an elastic material, such as polyurethane. The pallet 29 has a protrusion 30, which is inserted into the internal cavity of the probe 25. Assembled, the probe and the pallet form a tight connection, provided by the elastic properties of the material of the pallet. The landing force of the protrusion 30 of the pallet in the inner cavity of the probe 25 is selected so as to exclude the possibility of separation of the projectile during its transportation and equipment in the store. At the same time, the landing force is selected so as to ensure free separation of the probe from the pallet during firing. At the end of the pallet 29 there is a landing hole in which the metal cap 31 of the capsule is tightly inserted. In the inner cavity of the metal cap 31 there is a pyrotechnic composition 32 covered by a paper membrane 33. A standard Berdan type impact capsule in which the pyrotechnic composition is closed by a paper membrane can be used in a unitary projectile according to the present invention. Alternatively, a standard Berdan type impact capsule may be used in which the pyrotechnic composition is covered by a metal membrane when replacing a metal membrane with a paper membrane. The internal cavity of the metal cap 31 is connected with the internal cavity of the probe 25 by a gas channel made in the form of slots 34 in the pallet housing. The electrode 28, through the end of the coil 26 connected to it, is electrically connected to the metal housing of the probe. When applying high voltage between the metal cap 31 of the capsule and the metal body of the probe 25 between the end of the electrode 28 and the metal cap 31, a spark discharge passes through the paper membrane 33 and the pyrotechnic composition 32. As a result of the passage of the spark discharge, the pyrotechnic composition ignites.

On figa-E shows the cuts in the plane of the channels of the trunks of the device, which uses to discharge the target discharge of a high voltage capacitor, at various points in the implementation of the cycle of shot / extraction.

On figa shows the cuts in the plane of the channels of the trunks of the device in the initial position. Shop 11 with unitary shells 22 is located in the compartment of the dielectric frame 2. In the front protrusions 12 of the dielectric frame are metal trunks 14. The trunks 14 are separated from the front section of the store by dielectric channels 13. The metal trunks 14 are in contact with the electrodes 21 to which the leads of the high-voltage capacitor C1 are connected . The findings of the DC voltage generator, made in the form of a high-voltage transformer TP1 and a high-voltage rectifier diode VD1, are connected to the electrodes 19, which have an output into the internal cavity of the dielectric channels 13.

In the rear protrusions 15 of the dielectric frame 2 are placed dielectric gates 16. On the housing of the dielectric gates 16 there is a profile in the form of a gear rack. The teeth of the toothed rack of the shutters mesh with the teeth of the gears 17, mounted on the shaft of the corresponding electric gear motor. At the end of the rods of the dielectric shutter 16 is mounted a metal mirror 35 of the shutter.

On figb shows the cuts in the plane of the channels of the trunks of the device at the time of movement of the unitary cartridges in the starting position of charging a high voltage capacitor.

After the start button is pressed by the arrow, the electronic control circuit starts and the microprocessor issues a command to start moving the shutters. According to this command, the electric motors-reducers are turned on and through the rack-and-pinion transmission, the shutters 16 begin to move towards the metal trunks. When the shutters 16 move, unitary shells 22 move from the magazine 11 into the channels of the respective shafts 14. The barrel channel 14 and the channel in which the dielectric rod of the shutter 16 moves are aligned, and the diameter of the barrel channel and the diameter of the dielectric shutter rod are approximately equal (rod diameter the dielectric shutter has a slightly smaller diameter, so that the movement of the rod in the bore is free).

The charging of the high-voltage capacitor C1 begins at the moment when the metal shell of the unitary projectile 22 enters the cavity of the metal barrel 14, and the end face of the dielectric rod of the shutter 16, on which the metal mirror 35 is mounted, is at a sufficient distance from the cut of the dielectric channel 13 through which the unitary shells move to the trunk. Turning on the constant high voltage generator and applying voltage to the electrodes 19 is performed at the moment when the gate mirror 35 of each of the dielectric rods of the gate 16 is remote from the cut of the dielectric channel 13 by a distance S1. The value 81 is selected so as to exclude the possibility of a parasitic electric discharge passing through conductive elements that are not elements of the discharge circuit, for example, through the metal elements of a magazine.

In order for the DC high voltage generator to turn on at the right time, the microprocessor that controls the electronic circuit of the device uses an electronic timer. Based on the parameters of the electromechanical actuator that determine the speed of movement of the gate rods, the microprocessor can set such a time delay of the moment of turning on the constant-voltage generator (from the moment of turning on the electromechanical drive), at which, at the moment of turning on the high-voltage generator, the valve rods will move to the distance S1.

At a time when a constant high voltage is applied to the electrodes 19, the electrodes 19 and the metal shafts 14 are electrically closed through the metal shell of the projectiles 22 and the electric current from the constant high voltage generator through the electrodes 21 starts to charge the high voltage capacitor C 1.

FIG. 6B shows cuts in the plane of the channels of the device’s trunks at the moment the unitary cartridges move to the end position of charging the high voltage capacitor.

At the moment when the electrodes 19 come out of direct electrical contact with the metal shell of the projectile 22, the microprocessor issues a command to turn off the constant high voltage generator. To determine the time delay from the moment the high voltage generator is turned on until it is turned off, the microprocessor also uses an electronic timer. At the moment of switching off the constant high voltage generator, the high-voltage capacitor is charged to voltage U1.

On Figg shows the cuts in the plane of the channels of the trunks of the device at the time of moving unitary cartridges in the position of the shot.

After charging the capacitor to voltage U1 and turning off the high voltage generator, the dielectric gate rods continue to move. At the moment when the metal mirror 35 of the gates comes into direct electrical contact with the electrode 19, the shells are at the position of the shot and the microprocessor gives a command to re-briefly turn on the high voltage generator. At the moment when the shells are at the position of the shot, the electrodes 19 are briefly supplied with a voltage of a high-voltage generator U2, the value of which is greater than U1.

The magnitude of the charging voltage U1 of the capacitor C1 is determined by the parameters of the charging circuit and the charging time. Based on the known parameters of the charging circuit and the parameters of the electromechanical drive that determines the shutter speed, the charging time can be calculated so that at the maximum output voltage of the high-voltage generator U2, the high-voltage capacitor C1 is charged to a voltage U1 less than U2.

When the shells are at the firing position, the electrode 19 through the metal mirror 35 of the shutter is in contact with the metal cap 31 of the capsule, and the metal barrel 14, connected through the electrodes 21 to the terminals of the capacitor C1, contacts through the metal housing of the probe 25 and the metal conductor 26 with the electrode 28.

At the moment when each of the shells is at the shot position and a high voltage U2 is applied to the electrodes 19, a voltage equal to half the difference between U2 and U1 is applied between the metal cap 31 of the capsule and the electrode 28 of each of the shells. The value of the maximum output voltage of the high-voltage generator U2 is selected greater than the charging voltage of the capacitor U1 by an amount that ensures reliable passage of the electric discharge through the pyrotechnic compositions of the projectile capsules at the firing position. For example, the voltage U1 is chosen equal to 50,000 volts, and the maximum output voltage of the generator U2 is chosen equal to 60,000 volts. In this case, when the shells are at the shot position and a high voltage U2 is supplied to the electrodes 19, a voltage of 5000 volts is applied between the metal cap 31 of the capsule and the electrode 28 of each of the shells. The applied voltage causes a spark discharge, which passes between the metal cap 31 and the electrode 28 through the pyrotechnic composition 32. As a result of the passage of the electric discharge, the pyrotechnic composition ignites. Reliable passage of the spark discharge through the pyrotechnic composition of the capsule is ensured due to the fact that the distance between the electrode 28 and the metal cap 31 of the capsule is selected significantly less than the length of the dielectric tray 29, which separates the metal mirror 35 and the metal case of the probe 25 located at the position of the projectile shot.

After igniting the pyrotechnic composition, the combustion products through the slots 34 of the gas channel of the pallet fill the internal cavity of the probe 25. As a result of the gas pressure, the probe 25 is separated from the pallet 29 and accelerated in the channel of the metal barrel 14. At the time of the shot, the pressure acting in the barrel channel presses the pan 29 to the metal mirror 35. Due to the elastic properties of the material of the pallet, under the action of pressing force, the pallet 29 increases the degree of obturation with the walls of the channel, preventing the penetration of gases through the ring second gap between the outer surface of the valve stem 16 and the inner surface 13 of the dielectric channel.

At the time of the shot, the recoil acts on the shutter, directed in the direction opposite to the direction of motion of the probe, which tends to move the shutter 16 back. At the time of the shot, the recoil force is perceived by the teeth of the gear wheel 17, rigidly fixed to the shaft of the gear motor. Given the short duration of the recoil force acting at the time of the shot, the inertia of the rack and pinion gear, as well as the significant moment on the gear motor shaft, the backward movement of the shutter at the time of the shot will be insignificant and will practically not affect the process of firing.

In another embodiment, the device can be used to lock the shutter at the time of the shot. To lock the shutter at the time of the shot, for example, a spring-loaded lock with a protrusion engaged with the corresponding recess of the shutter can be used when moving the shutter to the position of the shot. An electromechanical or electromagnetic actuator used to move the shutter latch can be used to unlock the shutter. The shutter can be unlocked by an electronic control circuit, which, to release the shutter, activates the shutter lock actuator.

The short-term duration of the high-voltage generator to initiate the shot is selected so as to ensure that at least one spark discharge passes through the pyrotechnic compositions of the capsules. The experiments show that most pyrotechnic compositions of standard shock-type capsules can be reliably initiated by a single spark discharge passing through the pyrotechnic composition. According to the experiments, in order to reliably initiate the pyrotechnic composition of the capsule with a spark discharge for most standard capsules, it is sufficient that a voltage of the order of 2500 volts is applied between the cap 31 and the electrode 28 located in the immediate vicinity of the surface of the pyrotechnic composition 32.

On fig.6D shows the cuts in the plane of the channels of the trunks of the device at the time of departure of the probes from the channels of the trunks.

After separation from the pallets 29 and acceleration in the channels of the trunks 14, the probes 25 connected with the pallets by the conductor 26 opened from the cavity of the probe fly to the target. At the time of departure of the probes, each of the electrical conductors 26 is in contact with a corresponding metal barrel, each of which is connected via electrodes 21 to the corresponding terminal of the high-voltage capacitor C1. After the probes hit the target, the electric discharge circuit closes through the body of the object and the discharge of the high-voltage capacitor C1 passes through the body of the object.

6E shows cuts in the plane of the channels of the device’s trunks at the time of extraction of the pallets of the fired shells.

After the electric discharge of the high-voltage capacitor is transmitted through the body of the object, the pallets 29 of the shot shells are automatically extracted. The extraction is carried out by pushing the pallets 29 through the channels of the shafts 14 by the dielectric rods of the gates 16 moved in the barrel channel. In order to ensure the delivery of a high-voltage capacitor to the damaging electric discharge, it is necessary that the pallets be extracted after the probes reach the target. That is, the extraction of pallets should occur with a time delay between the moment of launching the probes and the moment of extraction of pallets. In the case of using a single discharge of a high voltage capacitor to hit a target, the value of the time delay should be slightly larger than the maximum flight time of the probes to the target. The value of the necessary time delay can be calculated on the basis of the data on the maximum shot distance of the device, the average speed of the probes at the distance of the shot, the shutter speed and the shutter movement during extraction of the pan. For example, the maximum shot distance is 10 meters, the average speed of the probes at the shot distance is 100 m / s, the shutter speed is 0.4 m / s, and the shutter travel required for extraction of the pan is 0.05 meters. In this case, the maximum flight time of the probes to the target will be 0.1 seconds, and the time delay for the extraction of pallets will be 0.125 seconds. Thus, by choosing the time delay of the extraction of pallets slightly more than the maximum flight time of the probes to the target, it is possible to ensure that the extraction of pallets will be carried out after the damaging discharge is transmitted through the body of the object.

Since the pallets are driven through the channels of the trunks during extraction, this ensures automatic cleaning of the trunks of the soot formed during combustion of the pyrotechnic composition after each shot.

After the extraction of pallets of shot shells is carried out, the microprocessor issues a control command to return the bolts to their original position. By this command, the electromechanical actuator is reversed, and the shutters move to the initial position shown in Fig. 6A. After that, the device can be fired. The device may have a firing mode translator, depending on the position of which, the microprocessor sets a certain algorithm for controlling the firing mode in semi-automatic or automatic mode.

In addition to the above-described variant of controlling the electronic circuit of a microprocessor-based device with an electronic timer, a feedback mechanism using shutter rod position sensors can also be used in the device according to the present invention for controlling the electronic circuit. As feedback sensors, for example, contact microswitches that operate in a certain position of the shutter rod when in contact with the corresponding protrusions on the shutter rod when moving the shutter can be used. In this case, the microprocessor control algorithm is formed depending on the state of the microswitches.

On figa-g shows the cuts in the plane of the channels of the trunks of the device using the discharge in the form of a series of consecutive pulses, at various points in the implementation of the cycle of shot / extraction. On figa-g shows a variant of the device using unitary shells with elements of fixation on the target, made in the form of a needle with a hook.

On figa shows the cuts in the plane of the channels of the trunks of the device in the initial position.

Shop 11 with unitary shells 22, equipped with locking elements on the target 24, is located in the compartment of the dielectric frame 2. In the front protrusions 12 of the dielectric frame are metal trunks 14. The trunks 14 are separated from the store by dielectric channels 13. The terminals of the high-voltage transformer TP2 are connected to the electrodes 19, which are brought into the internal cavity of the dielectric channels 13. The conclusions of the electrodes 19 in the cavity of the dielectric channels 13 are removed from the corresponding metal trunks 14 by a distance equal to the length of the dielectric unit tray. The metal trunks 14 are in contact with the electrodes 21, to which the leads of the high-voltage gas (air) spark gap P1 are connected.

In the rear protrusions 15 of the dielectric frame 2 are placed dielectric shutters 16, on the body of which a profile is made in the form of a gear rack. The teeth of the toothed rack of the shutters mesh with the teeth of the gears 17, mounted on the shaft of the corresponding electric gear motor. At the end of the rods of the dielectric shutter 16 is mounted a metal mirror 35 of the shutter.

On Figb shows the cuts in the plane of the channels of the trunks of the device at the time when the shells are at the position of the shot.

After pressing the start key with the arrow, the electronic control circuit starts, and the microprocessor issues a command to start moving the shutters. According to this command, the electric motors-reducers are turned on and, through the rack and pinion transmission, the bolts 16 move the unitary shells 22 from the magazine 11 into the channels of the respective trunks 14 to the shot position. After moving the shells 22 to the position of the shot, the microprocessor issues a command to turn off the gear motors and the shutters 16 stop. At the firing position, each of the electrodes 19 is in contact with a corresponding metal gate mirror 35, and the mirror 35 of each of the dielectric rods of the gate 16 is removed from the magazine cut 11 by a distance S2. The value S2 is chosen in such a way as to exclude the possibility of a parasitic electric discharge passing through conductive elements that are not elements of the discharge circuit, for example, through the metal elements of a magazine.

On Figv shows sections in the plane of the channels of the trunks of the device at the time of the shot.

When the unitary shells are at the firing position, the microprocessor issues a command to start the high-voltage pulse generator circuit, and high voltage pulses are generated at the terminals of the transformer TP2 connected to the electrodes 19. When applying high voltage to the electrodes 19, through the pyrotechnic composition of the capsules located in the dielectric pallets 29 and the air spark gap P1 passes a sequential spark discharge. As shown in Fig.6G, a spark discharge passes through the pyrotechnic composition 32 of each of the shells from the corresponding electrode 19, through a metal mirror 35, a metal cap 31 of the capsule to the electrode 28, electrically connected through a metal conductor 26 to the probe body 25 in contact with the metal barrel fourteen.

To ensure the passage of a sequential spark discharge through the pyrotechnic compositions of the capsules and spark gap P1, the maximum pulse voltage U3 at the output of the high-voltage transformer TP2 is selected more than the electric breakdown voltage U4 of the spark gap P1. For example, the value of U3 is chosen equal to 60,000 volts, and the value of U4 is chosen equal to 50,000 volts. In this case, the voltage applied between the electrode 28 and the metal cap 31 (Fig.6G) of each of the shells will be 5000 volts, which ensures reliable passage of the spark discharge through the pyrotechnic composition of the capsules.

After igniting the pyrotechnic compositions with a spark discharge under the influence of the pressure of the products of combustion, the probes 25 are separated from the pallets 29 and after acceleration in the channels of the shafts 14 fly to the target.

After the probes hit the target and secured to the target using the fixing elements 24, the electric discharge circuit connecting the electrodes 19 with the corresponding probe 25 by means of the corresponding metal conductor 26 closes through the body of the object and a series of consecutive current pulses formed on the terminals of the high voltage begins to pass through the body of the object transformer TP2. The passage of the discharge through the body of the object will be preferable to closing the discharge circuit through the spark gap P1, provided that the voltage drop in the discharge circuit being closed through the body of the object is less than the electric breakdown voltage U4 of the spark gap P1. For example, in the case of direct electrical contact of the probes with the body of the object, the voltage drop in the discharge circuit will be equal to the sum of the voltage drop in the current passage through the body of the object and the voltage drop across the current-carrying elements of the discharge circuit. Given that the equivalent resistance of a human current is about 1000 Ohms, for a pulse current of about 3 amperes (the characteristic current strength in a pulse for a Taser® X26 remote electroshock device), we obtain the magnitude of the voltage drop in the current passage through the object body of about 3000 volts. The voltage drop on the current-carrying elements of the circuit will be equal to the total voltage drop in the passage of spark discharge between the metal cap 31 of the capsule and the electrode 28 (Fig.6G) of the pallet of each of the shells. According to experiments, for reliable initiation of most standard capsules by a spark discharge, it is sufficient that the voltage between the capsule cap 31 and the pyrotechnic composition adjacent to the surface of the electrode 28 is of the order of 2500 volts. Thus, the total voltage drop in the discharge circuit, closed through the body of the object in the case of direct contact of the probes with the body of the object, will be about 8000 volts, which is significantly less than the electric breakdown voltage of the spark gap P1, which is 50,000 volts. Thus, in the case of direct contact of the probes with the body of the object, an electrical discharge through the body of the object will be preferable to closing the discharge circuit through the spark gap P1. An additional voltage drop in the discharge circuit, which is closed through the body of the object, can be caused by the presence of an additional air gap between the probes and the body of the object, for example, if one or both probes are fixed on the clothes of the object. However, choosing a value of U4 large enough, it is possible to ensure that the discharge passes through the body of the object, even if there is an additional air gap between the probes and the body of the object, until the voltage drop in the discharge circuit being closed through the body of the object is less than U4.

On Figg shows sections in the plane of the channels of the trunks of the device at the time of extraction of pallets of fired shells.

After an electric discharge in the form of a series of consecutive high-voltage pulses is transmitted through the body of the object, the microprocessor gives a command to turn on the electromechanical drive of the shutters and the pallets of 29 shot shells are automatically extracted. The extraction is carried out by pushing the pallets 29 through the channels of the shafts 14 by the dielectric rods of the gates 16 moved in the barrel channel. In order to ensure the delivery of a striking electric discharge in the form of a series of successive high-voltage pulses, it is necessary that the pallets be extracted after the probes reach the target, and the discharge will pass through the body of the object. That is, the extraction of pallets should occur with a time delay between the moment of launching the probes and the moment of extraction of pallets. If a discharge is used to hit a target in the form of a series of successive high-voltage pulses, the time delay value should be slightly larger than the total time required for the probes to reach the target and the discharge to pass through the body of the object.

For example, for a maximum shot distance of 10 meters and an average speed of the probes at a shot distance of 100 m / s, the maximum flight time of the probes to the target will be 0.1 seconds. The total discharge duration in the form of a series of consecutive pulses is, for example, 0.5 seconds. Then the time delay of the extraction of pallets, at which a maximum discharge of 0.5 seconds will be transmitted through the body of the object at the maximum distance of the shot, should be no less than 0.6 seconds, for example 0.625 seconds.

After the extraction of pallets of shot shells is carried out, the microprocessor issues a control command to return the bolts to their original position. By this command, the electromechanical actuator is reversed, and the shutters automatically move to the initial position shown in Fig. 7A. After that, the device can be fired.
