Description

The invention relates to the field of military equipment, in particular to means of destruction of highly protected samples of armored weapons (hereinafter - BTV).

Known devices for the defeat of highly protected BTV specimens, in which an armor-piercing tip located in the form of tubes interconnected by weakened jumpers is located inside the ballistic fairing in front of the kinetic action with a conical front part (see the description of the patent for the invention of the Russian Federation No. 2351885, 2007. Patent holder : State Unitary Enterprise “Instrument Design Bureau.” Authors: Shipunov AG, Kuznetsov VM, Zhukov VP, Alekseev AN, Kozlov DV Open edition).

In addition, a device for defeating highly protected BTV specimens is known, which is a swept feathered projectile, the body of which is made of durable and high-density material, and plumage from traditional structural alloys (see Armor-piercing feathered subcaliber projectile. Link: https: //ru.wikipedia. org / wiki / Armor-piercing_openny_podkalibernoy_ shell. Open edition. Prototype).

The known device allows for penetration of a relatively thick armor barrier at a considerable distance from the gun, to ensure stabilization of the body of the projectile during flight due to the action of aerodynamic forces, due to the plumage in the tail of the projectile body (similar to stabilization in the flight of an arrow). However, this device has the following drawback - plumage in the rear of the body of the projectile at high flight speed increases aerodynamic drag, which leads to a decrease in speed, kinetic energy and thereby breakdown ability, as well as a decrease in the probability of hitting the target as a whole.

The objective of the present invention is to increase the effective range of fire with an armor-piercing projectile, increasing the speed of the projectile body, its kinetic energy, shifting the center of mass mainly to the head of the projectile body, increasing the penetration ability and the probability of hitting the target as a whole.

The technical solution of the proposed invention is the use of a projectile body as part of an armor-piercing projectile equipped with magnetic pads and mounted to the shell of the projectile using bearings, and as part of the armament (gun barrel) of the winding, to which an electrical signal is supplied from a power source charged by a charger, with the aim of forming a magnetic field acting on the magnetic pads of the projectile body, to give the body a rotational movement, as well as a time relay, necessary for I delay passage from the power source to the trigger signal, acting on the propellant charge, with a view to its ignition, and giving the housing an initial speed of the projectile.

The technical result of the proposed invention is to increase the effective firing range, the flight speed of the projectile body, kinetic energy, the redistribution of the center of mass mainly in the head of the projectile body, increasing the probability of hitting the target as a whole.

At the same time, the device for the destruction of highly protected BTV samples is based on the fact that the shell body used in the armor-piercing sub-caliber projectile used during firing contains the projectile body with magnetic pads connected to the body using bearings necessary to center the projectile body and enable its rotation relative to the shell of the projectile under the action of a magnetic field of the winding mounted on the channel of the gun barrel. From an additionally installed power source, recharged by a charging device (generator), the electric signal is transmitted to a winding located around the barrel channel, in which an electromagnetic field arises, acting on the magnetic pads on the body of the projectile, giving the body a rotational movement. After a certain period of time, after the projectile body is unwound in the shell of the projectile, the electric signal is supplied to the time relay necessary to delay the electric signal to the trigger and ignite the powder charge. When the powder charge ignites, the shell of the shell moves along the bore and when it leaves it under the influence of strong air resistance is destroyed along with magnetic pads and bearings, while the body of the shell continues to move, stabilizing in flight due to the action of gyroscopic forces (rotation).

A device for the destruction of highly protected BTV samples, including a swept feathered projectile, the body of which is made of durable and high-density material, and plumage from traditional structural alloys, characterized in that the device uses a projectile body and a projectile body with magnetic pads located therein, attached to the body projectile bearings, using a charger to charge the power source, from which when you press the electric trigger transmit an electrical signal to the winding on the barrel, create the electromagnetic field that is applied to the magnetic pads on the body of the projectile gives it rotational motion, after a certain time interval, the electric signal is transmitted to the trigger via a time relay, ignite the powder charge, give the projectile body an initial speed, stabilize the body of the projectile in flight.

The invention is illustrated in FIG. 1, which shows a device for the destruction of highly protected BTV samples, where: 1 - time relay; 2 - trigger; 3 - electric wires; 4 - winding; 5 - shell body; 6 - magnetic pads; 7 - bearing; 8 - trunk channel; 9 - the body of the projectile; 10 - powder charge; 11 - charger; 12 - power source; 13 - electric start.

When firing from a gun, such as a tank gun, to penetrate a highly protected target, a device is used that includes an armor-piercing projectile and a coil on the gun’s bore. The shell consists of a housing in which the powder charge is located. When ignited, the powder charge gives the body of the projectile the initial velocity in the bore. A shell body with magnetic pads is placed in the shell body, which is attached to the shell body with bearings necessary for centering the shell body and making it possible to rotate relative to the shell body. When the operator presses the electric trigger, the electric signal is transmitted via electric wires from the power source to the winding installed around the barrel channel, in which an electromagnetic field appears that acts on the magnetic pads attached to the projectile body, giving the body a rotational movement. The power source is charged using a charger (generator). After a certain period of time, after the projectile body is unwound in the shell of the projectile, the electric signal is supplied to the time relay necessary to delay the electric signal to the trigger and ignite the powder charge. When the powder charge ignites, the shell of the shell moves forward along the bore and when it leaves it under the influence of strong air resistance it collapses along with the magnetic pads and bearings, while the body of the shell continues to move, stabilizing in flight due to the action of gyroscopic forces (rotation).

An example of the method. When firing a cannon at a highly protected target, an armor-piercing sub-caliber projectile is used that has a projectile body 5 in which there is a powder charge 10. The projectile body 5 contains the projectile body 9, with magnetic pads 6, fastened to the projectile body 5 by bearings 7. When pressing the electric trigger 13 there is a transmission of the electric signal through the wires 3 from the power source 12, recharged by the charging device 11, to the winding 4 on the bore 8, in which there is an electromagnetic field acting on the magnetic pads 6 on the bodies e of the projectile 9, imparting rotational motion to the projectile body 9 relative to the projectile body 5. After a certain period of time, after the projectile body 9 is unwound in the projectile body 5, an electric signal is supplied through the time relay 1, to the trigger 2, the ignition of the powder charge 10 occurs. When ignited powder charge 10, the shell of the projectile 5 moves along the bore of the barrel 8. When leaving the barrel 8, the shell of the shell 5 with magnetic pads 6 and bearings 7 is destroyed, and the body of the shell 9 continues to move, stabilizing in flight due to action of gyroscopic forces.

The proposed device allows to reduce the aerodynamic resistance of the air acting on the body of the projectile during flight, to increase its speed and effective range of fire, makes it possible to shift the center of mass to the head of the body of the projectile, to increase the length of the body of the projectile, which positively affects the penetration ability.
