Description

Method and device for preventing rear gas discharge and reducing recoil and noise using a variable modular outlet with variable gas return dome and side outlet angle adjustment. {Method and Device for Preventing Rear Gas Discharge, and Reducing Recoil and Noise using Variable Modular Side Outlet with Gas Swirling Variable Dome and Adjustable Side Emission Outlet Angle.}

The present invention relates to a method and device for preventing rear gas discharge and reducing recoil and noise using a variable gas return dome and a variable modular discharge port with adjustable side discharge angle.

Conventional muzzle brakes have a structure that releases gas forward, but have no effect in reducing recoil other than reducing the flame, and some recoil reduction devices (including structurally modified muzzle brakes and silencers) release gas rearward, preventing participants in battle from the side. Damage is caused by the released gas.

In order to improve this, the present invention modulates the dome (AA) for each stage, which consists of a hemispherical dome at the top and bottom that refluxes the gas released from the tip of the gun (gun) port , and has a front and rear of a certain size and a certain angle. The side gas outlet is configured symmetrically at an angle.

The dome (AA) formed at each stage disperses the emitted gas, reducing noise by half, and has the property of pushing the carbon base of the bullet ring as it circulates and passes through the central axis.

In the present invention, the direction of the gas that blocks or pushes the gas released to the rear is set as the first stage of discharging the gas anteriorly and laterally at the muzzle tip, and the gas discharge port is discharged posteriorly and laterally at each subsequent stage, and the internal gas is discharged backwards and laterally. It disperses noise by circulating gas in the dome of the caliber, and the second stage, which releases gas that pushes the gun (artillery) bullet, is configured by varying it in one or more modular ways.

This method has the feature of allowing users to reduce inflammation and noise by optimizing the different characteristics of gun heat at economical cost.

In addition, it is possible to apply a device structure in which manufacturing is unified at each stage and the emission angle can be adjusted by forming two separate stages by varying the emission angle of each stage.

In general, when a gun (artillery) is fired from a gun (gun) body, the incompletely burned propellant contained in the explosive gas reacts with oxygen in the air near the muzzle immediately after firing, generating a muzzle flame. The recoil caused by the muzzle flame and released gases is large enough to limit the user's use.

Therefore, a muzzle brake is installed at the end of the gun barrel to reduce the flame and recoil generated from the gun barrel when firing.

When a muzzle brake is installed at the end of the gun barrel, the explosive gases escape the muzzle and spread rapidly into the atmosphere, causing a large recoil that pushes the gun barrel backwards.

In addition, the explosion gas exiting the gun barrel reacts with oxygen due to a decrease in density and temperature, thereby reducing the size of the gun barrel flame. However, it does not reduce noise and recoil.

For example, the present invention can be used in relatively small-diameter gun barrels such as pistols, rifles, and machine guns, cannons, howitzers, mortars, and tanks and fighter jets ( It is applied to relatively large-diameter gun barrels used in large gun or artillery weapons, such as weapons installed on ships (including all aircraft), battleships, and submarines.

To explain in detail, if you look at the urbanization example as shown in FIG. 11 as a method step, the lower dome connecting end (40. 40-1) and the middle upper dome are attached to the tip of the gun (2). Connecting end (20); Or, it consists of the middle_lower_dome_connection stage (30), which connects the middle_upper_dome_to the first stage (1000) that discharges the emission gas (30-A) generated from the gun body to the front and side. By combining the end (20) and the middle_lower_dome_connection end (30), a circular dome and one or more posterior and lateral discharge ports are formed, so that the gas discharged into the inner diameter in front of the procentric axis is discharged to the top of the dome (AA). The gas (20-B), which is hit in all directions by the dome and refluxed, is discharged through the lower dome to the central axis through the inner bore, dispersing the explosion sound and reducing noise. ·The second stage (2000) of reducing the recoil of the gun body by releasing gas (20-A) to the side and one or more middle_upper_dome_connection ends (20) or middle_lower_dome_connection ends By combining (30), the upper dome connecting end (10) is formed to form a discharge port (11) of a certain angle (a) and a certain size rearward and lateral to the axial central axis. It is characterized by a three-stage method (3000) that further reduces the recoil of the gun (gun) barrel by releasing gas (10-A) to the rear and sides in addition to the discharged gas.

Figure 1 is a perspective view showing an embodiment of the present invention and shows an example of using the device of the present invention by fastening it to the tip of a gun barrel, based on the center line of the tip of the gun barrel from which the bullet 1 is ejected. By forming the gas discharge port at a forward angle and a rear angle, the combat participants on the sides and rear are not damaged by the gas discharged to the rear, and the characteristics of the gun body can be flexibly applied in a modular manner. Including application characteristics, the re-aiming ability, such as improving the flight stability and accuracy of flying bullets, is greatly improved by inducing gas reflux by the upper and lower semicircular domes (AA) formed inside.

For this purpose, as shown in Figures 2, 5, and 7, the upper and lower parts of the three fixed parts of Figure 10 are separated from the upper and lower parts, and the gas discharge angle is variously modified, and the present invention is combined into three fixed parts as shown in Figure 10.

An inner diameter larger than the diameter of the bullet ring is formed on the inner diameter of the center line of the central axis, and a fastening member for fastening other connecting ends is inserted. The connecting member consists of a hemispherical shape with a dome of a certain size on the upper and lower central axes and a gas discharge port on one side that forms an insertion port and a discharge port that releases gas to the rear and sides.

40 in FIG. 2 is the lower dome connection end, and 40-1 is the lower dome connection end equipped with the silencer mounting end 47 on which the silencer is mounted. The lower dome connecting end has an inner diameter of a bullet ring of a certain diameter formed on the inner diameter of the center line of the central axis, and the connecting member fastener and front and side to which fastening members for fastening other connecting ends are fastened. It is connected to the front end of the gun barrel with the discharge port on the half side and the barrel connection end, which forms the discharge port that releases the gas.

The explosive gas emitted from the tip of the gun barrel is released at an anterior and lateral angle as shown in FIG. 4 to prevent the gas emitted backwards from the rear and lateral sides of the connecting end, and the bullet ( 1) When the dome passes through the lower dome connection end and progresses to the next connection end, the hemisphere of the dome formed between the connection ends refluxes the gas in the dome (AA), which is formed in a circle, and gas (20-B) that pushes the anthrax of the bullet. ) and the gas (20-A) discharged to the rear on one side reduces the decrease in bullet speed and reduces the noise of the explosive gas.

Figure 3-10 shows a cross-sectional view showing the angles of the rear and side discharge ports of the upper dome connecting end, and the part A of Figure 9 is separated by the reference plane of the middle cross section of the discharge port.

Figure 3-20 is a cross-sectional view showing the angles of the front/rear and side discharge ports of the middle upper dome connection end, which is composed of the upper and lower parts of part A of Figure 9, and the discharge angle can be configured arbitrarily, and a hemispherical dome can be formed at the bottom of the cross section, thereby forming a dome by connecting another middle_upper_dome_connection end of Figure 3-20.

Figure 3-30 is a cross-sectional view showing the angles of the front/back/side discharge ports of the middle_lower_dome_connection end, and is a configuration having another discharge angle as shown in Figure 3-20.

The C-type illustrated in FIG. 5 is a configuration that connects 3-20 above vertically, and the B-type illustrated in FIG. 5 is a configuration that connects 3-20 upward and downward, and the configuration of FIG. 30 and FIG. 20 is illustrated in FIG. It is called the A-type illustrated in Figure 5, which is configured to connect the middle_lower_dome_connection ends up and down.

The above A-type, B-type, and C-type can form various emission angles, providing flexibility to suit the user's needs as the user optimizes them.

Figure 3-40-1 shows a cross-sectional view showing the angles of the front and side discharge ports of the lower dome connecting end provided with the silencer mounting end 47.

When installing a silencer, the lower dome connection end can be a member such as the example in Figure 3-40-1 that has a silencer mounting end. Depending on the user's purpose, the lower dome may be of a structure that is not mounted. The connection end 40 may also be used.

As shown in Figure 7, a method for preventing rear and lateral gas emissions and reducing recoil and noise using the variable gas reflux dome of the present invention and the variable modular discharge port for adjusting the angle of the lateral discharge outlet, which is fastened in various configurations as described above, is shown. Through the example in Figure 4, the gas flow during the bullet (1) passing through the inner bore is explained.

As illustrated in FIG. 4-A, the bullet (1) pushes out the bullet's bullet while passing through the lower dome connecting end (40-1) equipped with the silencer mounting end (47) for mounting the silencer. The present invention prevents devices such as conventional muzzle brakes from releasing gas only to the rear, as the gas is released through the discharge port, the gas pushing the bullet, and the flow of gas exiting the inner bore before the bullet escapes. By connecting the lower dome connection ends (40, 40-1) and members with different emission angles of 20 and 30 in Figure 3, the emission amount and emission angle of gas released anteriorly and laterally can be combined in various ways. It has the characteristic of being variable and able to push gas coming from the rear laterally and anteriorly and laterally.

In addition, Figure 4-B is a reference diagram showing an example of the flow of gas through the dome (AA) formed at the middle upper dome connection end and the middle lower dome connection end of the bullet (1). By refluxing the gas entering the inner bore, the refluxed gas (20-B) has the function of pushing the bullet base of the bullet (1) while reducing the explosion sound of the released gas, and discharging the gas at a certain angle through the outlet formed at the next connection end. It simultaneously has the effect of reducing recoil by releasing gas behind and to the sides.

Figures 4-C and 6 are reference diagrams showing an example of the flow of gas (10-A) in which gas is released backward and laterally when the bullet (1) passes through the upper dome connection end. It has the function of further reducing recoil through rear discharge by the discharge gas (10-A).

It includes the ability to configure and add all of these functions variably.

As an example of implementing the basic configuration consisting of, the middle_upper_dome_connection end and the middle_lower_dome_connection end are additionally configured to form a variable module inserted and fastened in the middle. Figure 5-C shows an embodiment of the variable module configuration of the present invention that can be additionally configured by variously configuring the middle_upper_dome_connection end and middle_lower_dome_connection end in 5-B. will be.

Figure 8 shows an example of implementation of the present invention, which is an example of a configuration in which a separate muzzle brake is mounted on the lower dome connection end provided with the silencer mounting end 47,

When explaining how to implement the device constituting the present invention,

Figure 9 is an embodiment of the module configuration method of the present invention, which can be implemented with a three-part module.

As shown in Figure 9-A, the upper upper dome connection end (10) and the middle upper dome connection end (20) can be composed of fixed parts combined, and as shown in Figure 9-B, the middle upper dome connection end (10) is combined. It constitutes a middle stage consisting of a fixed part in which the dome connection end and the middle_lower_dome_connection end are combined, and the lower dome connection end and the middle_upper_dome_connection end are combined as shown in Figure 9-C. By implementing and combining the middle stage composed of parts, the user can achieve a flexible configuration by adding or removing the components of Figure 9-B based on the fixed discharge angle.

In other words, as shown in Figures 10, 4, 5, and 7, the dome (AA) formed at the middle stage and the side and rear discharge ports are variable, so that the effect of reducing the recoil and noise of the user's gun body is achieved. there is.

Through this variable application, flight stabilization can be provided that can increase the bullet's speed and accuracy.

As above, according to this case, the discharge angle of the discharge port forms a forward angle or a rear angle based on the center line of the tip where the discharge gas is discharged, so that the combat participants on the side are not damaged by the gas discharged to the rear, and the gun (gun) is not damaged. ) It includes the characteristics of a modular application that can flexibly apply the characteristics of the god, and re-aiming capabilities such as improving the flight stability and accuracy of flying bullets by inducing gas reflux through the semicircular domes at the top and bottom formed inside. Provides greatly improved characteristics.
