Description

The invention relates to weapons with electric weapons.

Known remote electric shock weapon TASER (patent US 6636412), which transmits electrical energy to the target using two shells connected to the weapon using insulated wires. Shells, insulated wires and a TASER throwing energy source significantly limits the distance of the TASER shot, placed in a cartridge that attaches to the weapon when the shot is fired. When firing a TASER, projectiles are thrown at the target, pulling the initially stationary insulated wires packed in the side cavities of the cartridge. TASER projectiles are stabilized in flight due to the inertial force exerted on the tail of the projectile applied at the point of wire fixation. The opening of the wire from the cavity of the cartridge occurs under the influence of an impulse, which is transmitted to the wire by a projectile that pulls the wire from the cavity. The absence of a special wire tension mechanism in TASER leads to the fact that after the shells are fixed to the target, the wires sag and intersect. Therefore, in order to prevent shunting of the discharge circuit when crossing wires in a TASER shot, wires in high voltage insulation are used.

The disadvantage of the TASER method of transmitting electrical energy is the significant loss of kinetic energy of the projectile due to the fact that the insulated wire has a significant mass. This significantly limits the range of the TASER.

There is also a method of transmitting electrical energy to a target using uninsulated conductors. This method is used in remote stun guns described in WO 2009025575. WO 2009025575 describes an stun gun cartridge in which a conductor is packaged in a shell in the form of a tension spring, and the transmission of electrical energy to an object is carried out due to the spatial separation of the conductors and their tension, which ensures the lack of intersection of conductors after fixing shells on the target. The disadvantage of this method is the absence of an indication of the necessary conditions under which tension is ensured and the intersection of wires after hit by shells is excluded. The absence of an indication of the necessary conditions limits the possibility of practical implementation of the indicated method of transferring electrical energy.

The patent RU 2308668, selected as a prototype, describes a unitary cartridge of stun guns, in which the conductor is made in the form of a frameless coil, which is located in the cavity of the projectile. When fired, the projectile along with the coil is accelerated in the cartridge by a pushing tray. The disadvantage of this invention is that in the process of opening the wire from the cavity of the projectile, the wire has an effect on the projectile that adversely affects the stability of the projectile flight. In particular, when the conductor is opened from the cavity of the projectile, coil turns acting on the cavity walls in the tail of the projectile cause its precession and nutation. The presence of precession and nutation negatively affects the possibility of fixing the projectile on the target.

A known ESH projectile according to patent RU 2275576, selected as a prototype, including a hollow shell with a spiral conductor placed inside it in the form of a frameless coil. The shell can have a cylindrical shape or can be made in the form of a polyhedron, and the spiral-shaped conductor exactly repeats the internal shape of the shell. The value of the perimeter of the spiral conductor is chosen equal to the inner perimeter of the hollow shell. A decrease in the perimeter of the spiral conductor leads to an arbitrary displacement of the conductor inside the shell and a decrease in the service characteristics of the projectile. In the case when the spiral conductor repeats the internal dimensions of the hollow shell, a decrease in the accuracy of the projectile due to the high friction of the conductor against the inner surface of the shell is observed.

The aim of the proposed invention is to increase the accuracy of the hit of the projectile at the target by reducing friction when unwinding the spiral conductor on the inner surface of the hollow shell. The goal is achieved due to the fact that the shell is cylindrical, and the spiral conductor has the shape of a polyhedron. Due to the fact that the spiral conductor, having the shape of a polyhedron, is tightly placed inside the cylindrical shell and touches it only with its faces, it can dramatically reduce the area of surfaces rubbing when unwinding the conductor. This ensures alignment of the spiral conductor inside the shell.

This goal is also achieved by performing a shell in the form of a polyhedron, and a spiral conductor in the form of a frameless coil having the shape of a cylinder with a diameter equal to the diameter of the circle inscribed in the polyhedron.

Also, the goal is achieved by performing a hollow shell grooved.

Experimental testing of the proposed invention showed a significant (more than 2 times) reduction in effort when unwinding a spiral conductor in comparison with the prototype.
