Description

The invention relates to small arms, mainly to the structures of the barrel, in particular muzzle or muzzle, devices.

It is intended for installation on the barrel of small arms and can be used to improve its combat characteristics and operational properties, to reduce the reactive component from gases ejected from the barrel forward, and to reduce the impulse from braking the sliding part of the bolt to the stop.

In particular, a decrease in the action towards the reactive force of gases from the DCT, which is applied to the barrel and acts on all weapons, which compensates not only for one component of recoil, but also for all available components, reducing the recoil and reducing the barrel toss up when fired.

Refers to the area of recoil expansion joints.

By its functional purpose, it combines the function of a muzzle compensator and a muzzle brake. In the standard design, the tasks of the muzzle brake and the compensator are not combined, however, designs are known in which these functions are combined in one device.

A muzzle brake-compensator (DTK) is a muzzle device designed to slow down the rollback of the barrel of a weapon, as well as reduce or compensate for the toss of the barrel of a weapon. DTK uses for its operation the reactive force of gases coming out of the barrel following the fired projectile or bullet.

The task of the brake is to reduce or eliminate the recoil of the barrel when fired. To solve the problem of the muzzle brake to reduce the recoil of the weapon is solved as follows. Firstly, the minimum task is to exclude the possibility of gases flowing out of the barrel in the direction of the shot by scattering the gases following the bullet, to create a reactive force in the direction opposite to the shot (i.e. in the direction of the recoil force action), as a result which will increase the recoil of the weapon. And secondly, the maximum task is by maximizing the partial or complete outflow of these gases in the direction opposite to the direction of the shot, as a result of which to create a reactive force acting on the barrel in the direction opposite to the recoil, as a result of which partially or completely compensate for the recoil of the barrel.

The task of the compensator is to reduce or completely eliminate the toss of the barrel of the weapon caused by the process of firing, which adversely affects the accuracy of shooting. For example, this is necessary to reduce re-aiming time and improve shooting accuracy. The problem of the muzzle compensator can be solved by diverting part of the gases flowing from the barrel in the same direction as the toss of the weapon, as a result of which the arising reactive force of the outflowing gases will be directed in the direction opposite to the toss, which will compensate for the force causing the toss.

From the prior art, the invention is known "The muzzle device of the barrel of a firearm", patent RU 2611461, publ. 02/22/2017, IPC F41A 21/30 F41A 21/32, in which the body of the device is made up of integral cut-off chambers connected to each other, cut-off chambers connected to the bullet channel by gas channels with the front part of the cut-off chamber. This makes it possible to increase the effectiveness of the muzzle device and improve the operational properties of firearms, as well as expand the arsenal of design schemes used in muzzle devices. However, the disadvantage of this device is that the design is too complex, since several parts of complex geometric shapes are used, connected to each other. Due to technological errors, it is not possible to calculate and compensate for reactive forces with the required accuracy.

Known invention "Revolver with recoil compensation", patent RU 2561185, publ. 08/27/2015, IPC F41C 3/14 F41C 3/10, in which a drum with a groove forms a channel for escaping powder gases and a flow is formed to create a reactive force that reduces the effect of recoil. It uses the energy of powder gas streams breaking into the gap between the barrel and the barrel, which increases the accuracy of shooting. Reactive forces compensate for part of the recoil. However, it refers to firearms using the revolving principle of ammunition supply.

Known invention "Method for reducing the recoil of weapons and an ejector device for its implementation", patent RU 2413154, publ. 02/27/2011, IPC F41A 21/36, in which the powder gases are directed in opposite directions of the recoil and rebound of the weapon, while creating a vacuum vacuum in the diffusers of the zone, with the help of which the outside air is ejected through the channels connecting these zones with the atmosphere. The device has gas outlet holes that direct the powder gases in directions opposite to the recoil and rebound of the weapon when fired, and the axes of the channels ejecting the outside air are directed perpendicular to the generatrix of the inner surface of the central body. Allows to increase the efficiency of reducing the recoil of weapons when firing with the use of ejector devices in the design of muzzle brakes. However, Laval nozzles are used, which are very difficult to manufacture in mass production. They are not technologically advanced due to the presence of the constituent parts of complex geometry. In this case, the complexity and significant laboriousness of the selection of the arising axial and lateral forces that make up the total vector of the momentum of the powder gases acting on the barrel and on the weapon arise.

Also known is the useful model "Muzzle brake compensator", patent RU 189743, publ. 05/31/2019, IPC F41A 21/32 SPK F41A 21/32, equipped with a nozzle having a through channel containing several holes located at an angle to the axis of the nozzle with an inclination and the holes are located on both sides of the nozzle symmetrically relative to the longitudinal axis of the nozzle and are made for the entire the depth of the channel, and the lower part of the holes is closed by walls. The muzzle brake compensator interacts with the powder gases flowing from the barrel, due to the shape of the through holes, cuts off and redirects the gases in the right direction. However, it is ineffective, since the lower part is closed by ledges, and this row creates a force to compensate for the toss. However, the total number and size of the holes is not large, so the interaction is carried out with less gas, which affects the overall efficiency. The disadvantage of the known solution is its relatively low efficiency. Although the first two rows of holes are directed back in the same way, the holes are through, therefore the forces directed up and down compensate each other and do not give the effect of compensating for the barrel toss.

Closest to the proposed technical solution is the invention "Muzzle brake compensator", patent RU 2558504, publ. 10.08.2015, IPC F41A 21/36, which is made in the form of a tubular nozzle at the end of the barrel, contains serially connected coaxially located chambers, and the first chamber equipped with through holes, the second chamber is equipped with gas outlets running at an angle backward from the central channel to the outside and located on both sides of an imaginary vertical plane, and the holes in the first chamber are placed so that when installed on the end of the weapon barrel, they are oriented upward along the vertical plane , in order to compensate for the horizontal component of the barrel deflection when fired.

The invention makes it possible to obtain a simple design, in particular, in the form of a single piece, in which compensation is provided not only for recoil, but also for rebound when fired. However, the proposed design does not effectively compensate for the vertical deflection of the barrel (bounce) during firing, and also does not allow using the energy of gases accumulated in the chambers to counteract the outflow of the main stream of gases, which reduces the effectiveness of the compensator. In addition, there is an adverse effect on the bullet passing through the barrel, since the action of gases on the bullet passing through the expansion chambers deflects it towards the lowest pressure when fired. Bullet deflection is also facilitated by the insufficiently effective geometry of the chambers and gas outlets in terms of gas dynamics.

All analogs are conventionally divided into two classes with and without a preliminary side hole from the bore to the outside.

In the well-known DTK designs, the movement of gases is carried out through a through channel, and due to the excess pressure of the gases, they are pulled out of the vertical holes outward. At the same time, it is known from the laws of gas dynamics that the reactive force is calculated on the basis of the law of conservation of momentum under equal environmental conditions and depends on the velocity of the outflowing gas and the mass flow rate. The greater the mass of gas, and the higher the velocity of the gas ejected per unit of time, and, therefore, the higher the reactive force. In turn, the flow rate will depend on the pressure and temperature of the gas in the chamber.

In well-known DTK designs, the chambers can also have a significant volume and area of the total outlet section, which is many times larger than the sectional area of the borehole, which leads to a sharp expansion of the gas with multiple drops in pressure and temperature. As a result, the velocity of gas outflow from the side "windows", which play the role of a nozzle located in the chamber, will be small and the reactive force created by this outflow of gas will be insignificant.

It is known that a method of increasing the speed and, as a consequence, an increase in the reactive compensating force is used, when, after cutting the barrel, but before the beginning of the chambers in the body of the DTK, one or more side through holes are drilled, located up to the barrel bore, these holes have a diameter that is less than or equal to caliber. Then the gas in the barrel at high pressure and temperature will flow out of this hole at a high speed, creating a large reactive force. This is because the gas in the side hole will have practically the same high thermodynamic parameters as the gas in the wellbore, which will lead to gas outflow from the side hole at a high speed and create a high reactive force. However, such an outflow of gases will work for a very short time, only until the moment when the projectile will overlap the outlet section of the barrel bore before it enters the first chamber of the DTK. Immediately after the projectile body opens the outlet, the resistance to outflow in the longitudinal direction will sharply decrease, the pressure will also drop sharply and the velocity of the longitudinal movement of gases in the bore will increase. For example, the speed of the bullet in the Makarov pistol does not exceed 340 m / s, while the speed of the free outflow of hot powder gases will be on the order of 1900 m / s. An increase in the velocity of the longitudinal outflow of gases in the bore will lead to a sharp drop in the velocity and gas flow rate in the lateral direction. As a result, the side opening, at least, will lose its efficiency, and as a maximum, in accordance with the Venturi law, it will start working in the opposite direction - to eject atmospheric air. This principle is used, for example, in spray guns, carburetors, etc. Since the speed of movement of the projectile is high, and the length before entering the first chamber usually does not exceed one centimeter (otherwise the muzzle device will have unacceptable dimensions and weight), the locking time of the barrel bore is extremely short - about 1/1 000 000 seconds, and in during this time, even a large reactive force does not have time to complete significant work to compensate for the toss and / or recoil.

The proposed technical solution allows you to eliminate the above disadvantage.

As a result, an increased efficiency of compensation for both recoil and bounce of the borehole upwards is achieved, in particular, an increase in the forced gas flow rate through the lateral opening (s), and also a significant design simplicity is achieved.

This technical result is achieved due to the fact that the muzzle brake-compensator (DTC) is a muzzle device, made in the form of a tubular nozzle at the end of the barrel, and contains series-connected coaxially located chambers with working zones. The cameras are located in a housing with a through channel, which is located on the same longitudinal axis with the barrel of the weapon, the holes in the working areas of the cameras are placed so that when installed on the end of the barrel of the weapon, they are oriented perpendicular to the axis of the barrel, and are designed to slow the rollback of the barrel of the weapon, and also to reduce or compensate for the toss of the barrel of a weapon that uses for its operation the reactive force of gases coming out of the barrel following a fired projectile or bullet.

What is new is that the DTK is placed after cutting the barrel, and the internal through channel is conventionally divided into two working zones located in the DTK body. The first working zone is located from the front cut of the DTK to the second zone and is equipped with at least one chamber equipped with holes, which in total in cross section are at least twice the cross-sectional area of the barrel bore. The first zone is characterized by the fact that in it the average effective pressure of gases flowing out of the wellbore does not exceed ten atmospheres. The second working zone is located in close proximity to the bore cut and is equipped with at least one camera. The second working zone is characterized by the fact that in it the average effective pressure of gases flowing out of the barrel is more than ten atmospheres. In the chamber wall of the first zone, at least one through hole is placed, located on the side surface of the DTK body, extending orthogonally or at an angle directed away from the weapon barrel. In the wall of the chamber in the second zone, in close proximity to the cut of the bore on the side surface of the DTK body, at least one through side hole is placed, and in the opposite wall of the chamber, under the aforementioned through hole of the second zone, a blind hole is placed facing the central axis of the channel body DTK, which is (channel) a continuation of the bore of the weapon. The axis of the blind hole is normal or made at a design angle and runs from the inner wall of the chamber in the DTC body to its outer wall, while the axis of the blind hole intersects the DTC channel at a point distant from the point of intersection with the axis of the through lateral hole of the second chamber zone by no more than one gauge in any direction, and the depth of the blind hole is made at least half the diameter of the channel of the DTK body or at least half the diameter of the blind hole itself, and the total area of each hole in the second zone, both through and blind, is at least 1 sq. ... mm and no more than the area of two calibers of the barrel of the weapon.

The technical solution is illustrated in the drawing, which does not cover all variants of execution, both in terms of the number of holes and their angular position.

FIG. 1 shows a longitudinal section of a compensator brake.

FIG. 2 shows a graph of the comparison of the reactive force of the gases flowing out of the DCC.

The design of the muzzle brake-compensator (DTK) is made as follows.

DTK is a muzzle device and is located on the barrel (muzzle) (1) of small arms. DTK can be made as a single unit with the barrel due to its ease of manufacture. DTK can also be wound or otherwise rigidly attached to the barrel (1). DTK is made in the form of a tubular nozzle at the end of the barrel. Contains series-connected coaxially located chambers (2, 2 ", 3 and 4) with working areas (" a "and" b "). The cameras are placed in a housing (5) with a through channel ("c"), which is located on the same longitudinal central axis ("g") with the barrel (1) of the weapon. The holes (6, 7, 8, 9) in the working areas ("a" and "b") of the chambers (2, 2 ", 3 and 4) are placed in such a way that when they are installed on the end of the barrel (1) of the weapon, they are oriented along the vertical plane ("Y") The holes (6, 7, 8, 9) can also be oriented in any direction from the axis of the barrel (1). The holes (6, 7, 8) are designed to slow down the rollback of the barrel of the weapon. To reduce or compensate for the toss of the barrel of the weapon, in addition to the secondary holes (6, 7, 8), the hole (9) is mainly intended. In both working zones ("a" and "b"), the reactive force of gases escaping from the barrel (1) following the fired projectile or bullet is used for functioning.

DTK is placed after the cut (10) of the barrel, the internal through channel ("c") is conventionally divided into two working zones ("a" and "b"), located in the body (5) of the DTK. The first working zone ("a") is located from the front cut (11) of the DCT to the second zone ("b") and is equipped with at least one chamber (2 or 2 "or 3) equipped with holes (5,7,8 ), which in cross section are at least twice the cross-sectional area of the channel ("c") of the trunk (1). The first zone ("a") is designed so that in it the pressure of the gases flowing out of the barrel does not exceed, for example, ten atmospheres. The second working area ("b") is located in close proximity to the cut of the barrel (10) and is equipped with at least one hole (9). The second working zone ("b") is designed so that in it the pressure of the gases flowing out of the barrel is, for example, more than ten atmospheres. The calculation can be carried out for several hundred atmospheres, depending on the type of weapon.

At least one through hole (6 or 7 or 8) is placed in the wall of the chambers (2 or 2 "or 3) of the first zone (" a "). There can be from 1 to 8 of these holes. There are holes (6 or 7 or 8) on the side surface of the body (5) of the DCT. The axes of the holes (6,7,8), depart orthogonally or at a calculated angle directed away from the cut (10) of the barrel (1) of the weapon.

In the body of the DTK body (5) in the second zone ("b") in close proximity to the cut (10) of the channel ("c") of the barrel (1) on the side surface of the DTK body, at least one through side hole (9 ). There can be from 1 to 6 of these holes.

In the opposite wall of the body of the DTK body (5), under the aforementioned through hole (9) of the second zone ("b"), a blind hole (12) is placed. This hole (12) faces the central axis ("g") of the channel ("c") of the DTK body (5). Channel ("in") is a continuation of the channel ("in") of the barrel (1) of the weapon. The axis ("d") of the blind hole (12) is normal or made at a calculated angle and extends from the inner wall of the channel ("c") in the DTK body (5) to its outer wall. In this case, the axis ("d") of the blind hole (12) intersects the channel ("c") of the DTK at the point ("A"), in this particular case coinciding with the point ("A") of intersection with the axis of the through lateral hole (9 ) of the second zone ("b"), but in the general case, these points can be spaced from each other at some distance, but not more than one caliber. The points of intersection ("A") and ("A '") can be spaced from each other in any direction along the axis ("g") no more than one barrel caliber (1), depending on the technological features and errors made during production. The depth of the blind hole (12) is made at least half the diameter of the channel ("c") of the housing (5) of the DTK or at least half the diameter of the blind hole (12) itself. Displacement options are possible, since the displacement of the points of intersection of these holes with the axis even to the right, even to the left, even by the caliber will still allow the formation of vortices at the bottom of the blind hole (12), which support the axial flow of gases and prevent the main flow of gases from quickly passing the second working area and redirect part of the main gas flow upwards into the hole (9).

The area of the holes (9) and (12) in total for each hole (9 and 12) of the second zone ("b"), both through and blind, is at least 1 sq. Mm in cross section and not more than the area of two barrel calibers ( 1) weapons.

In the proposed device, a manufacturing method is used in which a blind side hole (12) is drilled as a continuation of the hole (9) perpendicularly or at an angle to the bore of the barrel (1) so that the d axis of the bore (12) intersects the bore and went deep into at least half the diameter of the bore, or the diameter of the hole (9), depending on which of these holes has a smaller diameter. Then the gas in the borehole will have high thermodynamic parameters (pressure and temperature), feed the side hole (9) and create a large reactive force not only during the closure of the hole in the partition (13) by the thrown body, but also during the entire process of gas outflow from the bore (about 5/10000 seconds), since a vortex will be formed in the formed depression, creating a zone of increased pressure and increasing the resistance to gas flow in the longitudinal direction, which leads to a slower release of pressure in the borehole bore and a longer high-energy forced flow gas through the side hole (9), as a result of which a large reactive force will act for a longer time, perform the greatest work and lead to increased compensation for toss and / or recoil, increasing the efficiency of the DTK as a whole.

The calculations of the proposed design are based on the following principles.

The physical reasons and the mechanism of action of the reactive force can be numerically characterized on the basis of the law of conservation of momentum (m * V) by determining the calculated value through a substitution in the formulas for conservation of momentum, instead of the mass, the mass of the second flow rate of the working gas is substituted. Thus, a calculated value is obtained when, with a larger mass of the outflowing gas at a higher velocity, the reactive force is determined, which increases with an increase in the mass and velocity of the outflowing gas through the side opening. Consequently, the gas pressure will depend not only on the speed of its outflow from any hole, but also on the density, and, as a result, not only the velocity "V" will grow, but also the mass "m". In other words, since the density is higher, then the mass of the ejected gas at the same volumetric flow rate will be greater. However, the velocity of gas outflow from any hole has a limit equal to the speed of sound for this gas under these conditions, thus, with an increase in pressure after reaching the limiting outflow velocity, a further increase in reactive force can be carried out only due to an increase in the density (mass flow rate) of the outflowing gas. Therefore, as soon as the outflow velocity reaches the speed of sound, a further increase in pressure will not lead to an increase in the velocity of the jet at the outlet from the orifice. However, in this case, the reactive force will continue to grow depending on the pressure increase, since the density of the outflowing gas will increase, which means that the mass of the gas ejected from the side hole will also increase per unit time.

The proposed technical solution works as follows. The design takes advantage of the above effect and helps to build up pressure in front of the side port in the second work area to generate increased reactive force.

Classic decks with large windows are built on the idea of a boat sail, where the jet presses into the partition like a sail, exerts pressure on it, is reflected and goes away outside the decks. The nature of this force is also reactive. Wind speed by rocket standards can be considered extremely low. That is why the sails of boats have a huge area. Gas leaving the barrel under high pressure into the DCT chamber, which is many times wider than the channel cross-section, begins to expand in exactly the same way as it would do, simply leaving the barrel into the air, its speed grows, but almost instantly drops pressure and drop are measured in multiples, not multiples. To turn the gas stream to the side, it is necessary to slow down, and although it still has a reserve of energy due to the high temperature and to the exit from the windows (or slots) of the DTC, it manages to accelerate somewhat. But all the same, by the time it leaves the windows (holes), the gas has not as high a velocity as is required for effective reaction, and the velocity that it could have, and, accordingly, create a smaller reactive compensating force. This leads to less than it could be, compensating force than if it was possible to keep the gas pressure close to what it had at the exit from the bore. So the traditional multi-slot design is very cumbersome and ineffective, inherited from the physical concepts of the gas outflow process at the beginning of the 20th century, and is long outdated.

Thus, the proposed design overcomes the main disadvantage of all analogs in which through holes or slots are present. These analogs have low efficiency due to the creation of a small reactive force, since there is a rapid loss of gas pressure in the expansion chambers.

In the proposed design of the DTK, chambers are additionally made, however, 93% of the thrust creates an opening located in the second working zone, and subsequent chambers, for example, there can be one, two or three or more, discharge the remaining 7% of gases emitted from the barrel. In other words, they are not the main compensator, all other things being equal, and can be removed from the structure altogether, since the presence of a chamber with a blind hole saves on the weight and size of the entire DTC. The purpose of the cameras in the working zone "a" is to scatter the gas stream following the bullet (thrown by the body) to improve the accuracy of fire. This is due to the fact that the bullet (projectile body) has deviations from the ideality of the shape and there is an inhomogeneous composition of the powder jet of gases ejected from the barrel of the weapon, these gases are not uniformly mixed with the air in which the bullet is flying, this circumstance greatly affects the gas jet, creating an effect that swirls this stream. Since the effect is based on the fact that the swirling powder stream emanating from the barrel acts on the bullet (projectile body) from behind, giving it asymmetrical disturbances in an unpredictable direction, this negatively affects the accuracy of fire. Although in analogs the partitions of additional chambers make it possible to reflect part of the gases following the bullet and thereby weaken this effect, this is not enough, since too little gas mass is vented in chambers with a through hole. In the proposed design, a larger mass of gas is vented in chambers with blind holes, which leads to a greater weakening of the jet hitting the bottom of the bullet and to an improvement in accuracy.

Thus, a DTK with a side hole from that part of the bore where there is still a lot of pressure, the presence of a blind hole makes it possible to increase the efficiency of compensation for the toss and deceleration of the gas jet in the following chambers, which is much, many times more effective. This happens because in structures with through holes it is not possible to remove the gas due to the speed of the gas jet in hundreds of meters per second, therefore, the inertial force of the gas molecules interferes with turning the jet at a right angle towards the hole. In this case, the effect discovered by Venturi is triggered, with the use of which carburetors and atomizers are built. Thus, with a through hole in the bore equal to or smaller than the bore, gas will escape from it at a high speed outward, which means it will create a reactive force, but in time this reactive force will be created for a very short time, the gas will escape through it only as long as the bullet will be in the channel of the DCT and close it, but as soon as the bullet leaves the channel, the gas will rush with an ever-increasing speed along it and begin to suck in the outside air from the atmosphere through this through hole into the barrel or DCT.

To prevent this from happening. in analogs, the length of the side slot of the chamber is increased so that the gas is not sucked in, but has time to deviate and leave through the hole to the side, and for this the chamber is enlarged. In this case, again in the increased volume, the gas loses pressure and the reactive force decreases.

The proposed design with a chamber with a blind side hole allows the gas stream that enters it and does not have the ability to flow through it from the other side, swirl and go back into the channel. But since gas molecules have weight and it is impossible to deploy them at a speed in one place 360 degrees, gas molecules are forced to move along a certain radius dependent on the flow velocity, which is determined from the equilibrium conditions. In this case, on the one hand, a centrifugal force will act on the molecule, and on the other hand, it will be subject to pressure from the main stream flowing along the channel. As a result, a gas-dynamic ridge is obtained, which is an obstacle, narrowing the channel at this point, and accordingly, before this obstacle, the pressure in the channel becomes greater and more gas is ejected into the side through hole opposite, and this process takes longer than in structures with classical ribs ... As a result, the presence of a gas-dynamic ridge leads to the creation of not only a significantly greater reactive force, but it also acts for a longer time. Since the work is an integral value of the force over time, the compensation of recoil and toss becomes more effective.

Thus, in the proposed design, increased pressure is organized in the area under the through hole in the channel. An organized swirl, which prevents the direct flow of the jet in the channel and increases the pressure in the channel, increases the flow rate through the side through hole, and, consequently, the reactive force created by it.

The effectiveness of the proposed design is confirmed by tests in comparison with structures with a through hole or with structures with partitions, which is reflected in the graph.

FIG. 2 shows a graph comparing the reactive force of the gases flowing from the DCT, in which the upper curve characterizes the reactive force acting on the DCT without a side hole (9,12), and the lower curve characterizes the reactive force acting on the DCT with a side hole (9,12).

Experimental data confirm the technical result and industrial applicability of the proposed design.

Consequently, the technical result is achieved to increase the efficiency of compensation for both recoil and bounce of the borehole upwards, in particular, increase the forced gas flow rate through the side opening (s). In addition, this result is obtained with a significant simplification of the design.
