Description

The invention relates to the field of military affairs and has the goal of significantly increasing the effectiveness of artillery and small arms, it can also be used for scientific research purposes, for example, to create installations for high-speed body throwing in studies of impact of bodies with obstacles.

It is known that the real speed of artillery shells and small arms bullets does not exceed 1,500 meters per second. However, at the present stage of the development of barrel systems, the development of conventional weapons with higher projectile throwing speeds is required, which can significantly increase their throwing range and penetration ability.

There are various methods and means of increasing the speed of throwing using barrel systems [1, 2, 3]. Including by increasing the length of the barrel, reducing the mass of the projectile, improving the quality of the powder, including the calorie content of the powder, specific gas formation during its combustion, if possible, gases with a lower molecular weight, the choice of the optimal shape of the powder grains, etc. The closest prototype of the present invention is [ 1], in which the preliminary acceleration of the body is carried out in the traditional way of throwing with powder barrel systems, and the additional acceleration to excess artillery speeds is carried out by a stream m detonation product of an explosive charge (BB) after the departure of the projectile barrel powder system, which are formed into a narrow directed flow, overtaking projectile with its rear side. To implement the method, a device is created, which is a collapsible design, in which a explosive-shaped explosive charge is placed, the design has an axial channel for the passage of the missile body. The drip is coaxially connected to the powder barrel system using an adapter. The outer funnel-shaped and inner conical parts of the shell on the back are fastened with a lid, which has evenly distributed openings for placement of electric detonators in them. In the front of the shell channel there is a through hole normal to its longitudinal axis. A wire end closure of the explosive detonation circuit is fixed in the hole at the time of its passage by a missile projectile.

Using the explosive accelerator according to this invention, it is possible to obtain projectile throwing speeds of up to 3000-4000 m / s. An explosive accelerator [1] can be considered the closest analogue, but it has several disadvantages:

upon detonation of the explosive charge placed in it, the accelerator shell is crushed into fragments that fly apart at a speed of 1200-1500 m / s, which requires serious protection;

a device of a one-time explosive accelerator, which does not allow to obtain a satisfactory rate of fire;

there are difficulties mounting the explosive accelerator on the barrel of the powder system.

The objective of the invention is to increase the speed of throwing shells to 2500-3000 m / s, devoid of the disadvantages of the prototype.

A device for increasing the speed of projectile throwing using barrel powder systems is shown schematically in FIG. 1. It includes a barrel (Pos. 1) with a combustion chamber of a powder charge and a sleeve (Pos. 3, 5), an aiming device, a barrel placement and fastening device, characterized in that the combustion chamber is made in two sections, the front section (Pos. .3) is designed to accommodate a combustible sleeve with a powder charge in it and the rear section (Pos. 7) for filling under high pressure a combustible, flammable liquid, for example, hydrogen peroxide. Sections (5) and (7) are separated by a movable piston (Pos. 6) with injectors (Pos. 4). Section (7), in turn, is separated by a jumper (Pos. 10) with a check valve (Pos. 13), which separates the piston tank (Pos. 7), intended for direct injection of liquid into the section (Pos. 5) from the main tank (Pos. . 9) for the flammable liquid of subsequent shots. This part of this section has a fitting for filling the section with a flammable liquid (Pos. 15).

The operation of the device is as follows. When fired, the powder charge burns in the chamber, the pressure in it rises to the maximum value, the projectile (Pos. 2) starts moving towards the muzzle of the barrel. After reaching the maximum pressure of the powder gases in the barrel as the projectile moves and the projectile space increases, the pressure in the projectile space decreases. The piston (Pos. 6) with the beginning of the movement of the projectile moves in the opposite direction. At this moment, the non-return valve is closed, and combustible liquid from the piston space is injected under pressure through injectors (Pos. 4) into the section (Pos. 3) where, at high temperature of the powder gases, it ignites and burns, increasing the pressure in the projectile space and thereby increasing projectile speed.

After the combustion of the liquid injected from the piston chamber of the combustion chamber through the check valve, the fluid from the rear section flows into the piston chamber and the combustion chamber comes to its original state for the next shot.

To reload the gun and prepare it for the next shot, it is necessary to turn the shutter (Pos. 12) with the handle (Pos. 12) to disengage the cuts (Pos. 10a) of the cylindrical piston with the breech thread and continue to rotate the shutter frame to remove the shutter piston from the breech. To load the gun, it is necessary to put a shell into the breech, put the bolt so that the threaded sections (Pos. 10a) fall against smooth sections in the bolt nest and slide it into the nest (breech). After that, turn the shutter and the threaded sections will enter the threaded sections of the breech.

Such a device and its functioning allows us to solve the problem of increasing the speed of projectile throwing up to 2500-3000 m / s, which exceeds the speed of modern standard damaged elements by 2 ... 3 times.
