Description

A method and device for preventing rearward gas discharge and reducing recoil and noise using a variable modular discharge port with a gas reflux variable dome and a lateral discharge port angle adjustment.

[0001] The present invention relates to a method and device for preventing rearward gas discharge and reducing recoil and noise by using a variable modular discharge port with a gas reflux variable dome and a lateral discharge port angle adjustment.

[0002] Conventional flash hiders, which emit gas forward, only have the effect of reducing flames and do not have the effect of reducing recoil. Some recoil reduction devices (including structurally modified flash hiders and silencers) emit gas backward, causing damage to combat participants on the side due to the emitted gas.

[0003] To improve this, the present invention modularizes a dome (AA) composed of upper and lower hemispherical domes that circulate gas emitted from the tip of a gun (cannon) into each section, and symmetrically configures side gas discharge ports with a constant size and a constant angle in the front and rear.

[0004] The dome (AA) formed for each section has the characteristic of dispersing the emitted gas to reduce noise and pushing the bottom of the bullet (shell) that passes through the central axis by circulating.

[0005] In the present invention, the first stage is configured to block the gas emitted rearward or push it sideways by discharging the gas forward and sideways at the tip of the muzzle, and the second stage is configured to discharge the gas to the rear and side through the gas discharge port for each subsequent stage, disperse noise by circulating the gas in the dome of the inner diameter, and release the gas that pushes the gun (cannon) bullet by varying it in one or more modular ways.

[0006] This method has the advantage of allowing users to optimize the different characteristics of the gun (gun) column at an economical cost, thereby reducing inflammation and noise.

[0007] In addition, a device structure that can control the emission angle by forming two separate stages with different emission angles for each stage and manufacturing them in a single stage can be applied.

[0008] Typically, a gunshot fired from a gun barrel generates a muzzle flame immediately after firing, as the incompletely combusted propellant contained in the explosive gas reacts with oxygen in the air. The recoil from this muzzle flame and the emitted gases is so severe that it limits the user's use.

[0009] Therefore, in order to reduce the flame and recoil generated from the gun barrel when firing, a flash hider is necessarily installed at the end of the gun barrel.

[0010] When a flash hider is mounted on the end of a gun barrel, the explosive gases quickly spread into the atmosphere as they exit the muzzle, and the recoil that pushes the gun barrel backwards is large.

[0011] Additionally, the explosive gases escaping the barrel can reduce the size of the barrel flame generated by reacting with oxygen due to the decrease in density and temperature. However, this does not reduce noise and recoil.

[0020] The above-mentioned well-known technology is limited in scope for specific implementation as it is a shape for a flame suppressor and silencer that reduces flame.

[0021] However, the present invention can bring about a performance enhancement that is further improved than the above-mentioned well-known technology, and includes the characteristics of modular application that can be variably applied to form the front and rear angles of the gas discharge port based on the center line of the front end from which gas is discharged from the gun (cannon) barrel so that the side and rear combat participants are not damaged by the gas discharged to the rear, and to reduce recoil and noise according to the characteristics of the gun (cannon) barrel, and to improve the re-aiming ability such as improving the flight stability and accuracy of the flying bullet by inducing gas circulation by the upper and lower semicircular domes formed inside, and relates to a method and device for preventing rear and side gas discharge and reducing recoil and noise using a variable modular gas circulation dome (AA) and a side discharge port of a constant angle.

[0022] The present invention aims to provide a device that controls the discharge angle of gas generated from a gun barrel by configuring a variable module, increases the flight stability and speed of a bullet by configuring a dome that circulates gas within the inner diameter, reduces the recoil of the gun barrel at an economical cost by using a variable module fastening method so that it can be optimized according to the characteristics of the gun barrel, prevents the rear discharge of the discharged gas, and induces an increase in the speed and flight stability of the bullet.

[0023] The present invention provides a method and device for preventing rear gas discharge and reducing recoil and noise using a dome (AA) for gas reflux and a variable modular discharge port with a side discharge port angle adjustment for implementing the above-described purpose.

[0024] A barrel_connection part (45) having an inner diameter corresponding to the outer diameter of the tip (2) of the gun (cannon) is formed, and a lower_dome_connection part (40, 40-1) having a predetermined angle (D) in the front and side directions and a predetermined size of the discharge port_lower part (46) is formed in the front part of the barrel_connection part in the direction of the central axis.

[0026] The above one or more upper dome connection ends (20) and lower dome connection ends (30) are combined to form a dome (AA) of a certain size with a central axis for refluxing one or more gases, and the upper dome connection end (10) is formed with a discharge port upper portion (11) of a certain size and a certain angle (a) toward the rear and side of the axial central axis, and is connected with a connecting member (5).

[0027] The tip (2) of the gun barrel is configured with a lower dome connection (40, 40-1) and a middle upper dome connection (20) or a middle lower dome connection (30) to release the gas (30-A) generated from the gun barrel forward and sideways, thereby preventing the gas from being released to the rear.

[0028] By combining the upper dome connection (20) and the lower dome connection (30), a circular dome and one or more rear / side discharge ports are formed, so that the gas discharged through the inner diameter in front of the core axis is hit in all directions by the upper dome of the dome (AA), and the refluxed gas (20-B) is discharged through the inner diameter by the lower dome toward the central axis, thereby reducing noise, and the gas (20-A) is discharged to the rear / side in addition to the discharged gas (20-B) that has escaped through the inner diameter, thereby reducing recoil of the gun barrel.

[0029] The upper_upper_dome_connection_section (10) is formed by combining one or more of the above-mentioned upper_dome_connection_sections (20) or lower_dome_connection_sections (30) to form an upper discharge port (11) of a certain size and a certain angle (a) toward the rear and side of the axial center axis, thereby emitting gas (10-A) toward the rear and side in addition to the discharged gas that has escaped through the inner diameter, thereby further reducing the recoil of the gun (cannon) barrel.

[0030] According to the present invention, the front and rear angles of the gas discharge port are formed based on the center line of the front end from which gas is discharged from the gun barrel, so that the participants in the battle on the side and rear sides are not damaged by the gas discharged to the rear, and the characteristics of modular application that can be variably applied to reduce recoil and attenuate noise according to the characteristics of the gun barrel are included, and the re-aiming ability, such as the flight stability and accuracy of the flying bullet, are improved by inducing gas circulation by the upper and lower semicircular toms formed inside.

[0053] Figure 10 is an embodiment of the present invention combined with three fixed parts.

[0054] Figure 11 is an example illustrating the steps of a method for three-stage gas discharge and a method for reducing noise / recoil.

[0055] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0056] The present invention is applicable to relatively small-caliber gun barrels used in small gun barrels such as pistols, rifles, and machine guns, and relatively large-caliber gun barrels used in large gun barrels or artillery weapons such as cannons, howitzers, mortars, and weapons installed on tanks, fighters (including all aircraft), warships, and submarines.

[0057] To explain in detail, in terms of the steps of the method, through an urbanization example such as in Fig. 11, the front end (2) of the gun barrel includes a lower_dome_connection end (40, 40-1) and a middle_upper_dome_connection end (20); Or, the first stage (1000) that discharges the discharged gas (30-A) generated from the gun barrel forward and laterally by configuring the middle_lower_dome_connection terminal (30), and the middle_upper_dome_connection terminal (20) and the middle_lower_dome_connection terminal (30) are combined to form a circular dome and one or more rear and side discharge ports, and the gas discharged to the inner diameter in front of the core axis is hit in the forward direction by the upper dome of the dome (AA) and the refluxed gas (20-B) is discharged to the inner diameter by the lower dome toward the central axis to disperse the explosion sound and reduce noise, and the second stage (2000) that discharges the gas (20-A) to the rear and laterally in addition to the discharged gas (20-B) that escaped from the inner diameter to reduce the recoil of the gun barrel, and the second stage (2000) that comprises at least one middle_upper_dome_connection terminal (20) or middle_lower_dome_connection terminal (30) It is characterized by a three-stage (3000) method in which the upper_upper_dome_connection end (10) is formed with a discharge port_upper part (11) of a certain size and a certain angle (a) rearward and laterally with respect to the axial center axis, and the gas (10-A) is discharged rearward and laterally in addition to the discharged gas that has escaped through the inner diameter, thereby further reducing the recoil of the gun (cannon) barrel.

[0058] FIG. 1 is a perspective view showing an embodiment of the present invention, showing an example of using the device of the present invention by attaching it to the front end of a gun barrel, and forming a gas discharge port at a front angle and a rear angle based on the front center line of the gun barrel from which the bullet (1) is discharged, so that the side and rear sides of the combat participants are not damaged by the gas discharged to the rear, and includes the characteristic of modular application that can flexibly and variablely apply the characteristics of the gun barrel, and greatly improves the re-aiming ability, such as improving the flight stability and accuracy of the flying bullet, by inducing gas circulation by the upper and lower semicircular domes (AA) formed inside.

[0059] To this end, as shown in FIGS. 2, 5, and 7, the three fixed parts of FIG. 10 are separated into upper and lower parts to change the gas discharge angle in various ways, and an example of the present invention is shown by combining the three fixed parts as shown in FIG. 10.

[0060] 10 of Fig. 2 is a cross-sectional view of the upper upper dome connecting section, in which an inner diameter larger than the diameter of the bullet (cannon) ring is formed on the inner diameter of the center line of the central axis, and a connecting member insertion port into which a connecting member for connecting other connecting sections is inserted, and a discharge port on the semi-side forming a discharge port for discharging gas to the rear and side.

[0061] 20 and 30 of Fig. 2 are cross-sectional views of a stop_upper_dome_connection, in which an inner diameter portion larger than the diameter of a bullet (cannon) ring is formed on the inner diameter of the center line of the central axis, and a connecting member_insertion port into which a connecting member for connecting other connecting members is inserted, a gas discharge port on one side forming a discharge port for discharging gas to the rear and side, and a hemispherical shape of a dome of a certain size on the central axis of the upper and lower ends.

[0062] 40 in Fig. 2 is a lower dome connection, and 40-1 is a lower dome connection having a silencer mounting section (47) for mounting a silencer. The lower dome connection has an inner diameter of a certain diameter of a bullet (gun) ring formed on the inner diameter of the center line of the central axis, and a connection member_tightening member to which a connection member for connecting other connection members is connected, and a discharge port on the anti-side forming a discharge port for discharging gas forward and sideways, and a barrel connection unit that is connected to the front end of the barrel.

[0063] As shown in Fig. 4, the explosive gas emitted from the tip of the gun barrel is emitted as gas (30A) at a forward and lateral angle, thereby preventing the gas emitted to the rear and side of the subsequent connecting end from flowing backward, and when the bullet (1) passes through the lower_dome_connecting end and advances to the next connecting end, the gas (20-B) that pushes the bottom of the bullet by circulating the gas in the dome (AA) formed in a circular shape between the connecting ends is configured to reduce the decrease in the speed of the bullet and reduce the noise of the explosive gas.

[0064] Figure 3-10 is a cross-sectional view showing the angle of the rear and side discharge ports of the upper_upper_dome_connection, and is obtained by separating part A of Figure 9 with the reference plane of the middle cross-section of the discharge port.

[0065] The upper and lower parts of the A part of the above Fig. 9 are separated and configured as the lower part, and Fig. 3-20 is an example of a cross-sectional view showing the angles of the front / rear / side discharge ports of the middle_upper_dome_connection end, so that the discharge angle can be arbitrarily configured, and a hemispherical dome can be formed at the lower part of the cross-section to connect another middle_upper_dome_connection end of Fig. 3-20 to form a dome.

[0066] Figure 3-30 is a cross-sectional view showing the angles of the front / rear / side discharge ports of the stop_lower_dome_connection, and is a configuration having another discharge angle of Figure 3-20.

[0067] The configuration for vertically connecting the 3-20 above is C-type as exemplified in Fig. 5, the configuration for vertically connecting the 30 above is B-type as exemplified in Fig. 5, and the configuration for vertically connecting the middle_lower_dome_connection terminals of Fig. 30 and Fig. 20 is A-type as exemplified in Fig. 5.

[0068] The above A-type, B-type, and C-type can form various emission angles, providing variability that allows the user to optimize and meet the user's needs.

[0069] Figure 3-40-1 shows a cross-sectional view showing the angles of the front and side discharge ports of the lower dome connection end having a silencer mounting end (47).

[0070] When mounting a silencer, the lower dome connection section may use a member such as the example of Fig. 3-40-1 having a silencer mounting section, and a lower dome connection section (40) without a mounting structure may be used depending on the user's purpose.

[0071] By connecting the different emission angles of 20 and 30 of FIG. 3 to the lower dome connection (40-1) of FIG. 3-40-1, the characteristics of variability are also included, which enable the emission amount and emission angle of the gas emitted forward and sideways to be combined at various angles.

[0072] As shown in Fig. 7, a method for preventing rearward and lateral gas discharge and reducing recoil and noise using a variable modular discharge port with a variable gas reflux dome and a lateral discharge port angle adjustment according to the present invention, which are configured by being connected in various configurations as above, is explained through the example of Fig. 4, showing the gas flow during the process of a bullet (1) passing through the inner diameter.

[0073] As illustrated in Fig. 4-A, while a bullet (1) passes through a lower dome connection (40-1) equipped with a silencer_mounting section (47) that is equipped with a silencer, the exhaust gas that pushes the anthrax of the bullet is emitted through the discharge port, the gas that pushes the anthrax, and the gas that comes out before the bullet through the inner diameter before the bullet comes out, so that, unlike conventional devices such as flash hiders that only emit gas to the rear, the lower dome connection (40, 40-1) of the present invention and members having different emission angles such as 20 and 30 of Fig. 3 can be connected, thereby enabling the emission amount and emission angle of the gas emitted forward and sideways to be combined in various implementations, thereby having the characteristic of being able to push the gas coming to the rear sideways and forward and sideways.

[0074] In addition, FIG. 4-B is a reference diagram showing an example of the flow of gas passing through a dome (AA) formed at the upper and lower dome connection ends of a bullet (1), which circulates gas drawn into the inner diameter by the dome, thereby reducing the explosion sound of the released gas, and has the function of pushing the bottom of the bullet (1) with the circulated gas (20-B), and at the same time, has the effect of reducing recoil by emitting the gas to the rear and side at a certain angle through the discharge port formed at the next connection end.

[0075] Figures 4-C and 6 are reference drawings showing examples of the flow of gas (10-A) that is discharged rearward and laterally when a bullet (1) passes through the upper_upper_dome_connection. It has the function of further reducing recoil due to the rearward discharge by the discharged gas (10-A).

[0076] It includes the ability to add all of these features in a variably configured manner.

[0077] FIG. 5-A and B show examples of a basic configuration comprising an upper_top_dome_connection end, a middle_upper_dome_connection end, a middle_lower_dome_connection end, and a lower_dome_connection end having a silencer mounting end (47), and a variable module configuration is formed by additionally configuring a middle_upper_dome_connection end and a middle_lower_dome_connection end and inserting them in the middle to be connected. FIG. 5-C shows an embodiment of a variable module configuration of the present invention, which can be additionally configured by configuring various middle_upper_dome_connection ends and middle_lower_dome_connection ends in addition to 5-B.

[0078] Fig. 8 shows an example of an embodiment of the present invention, which is an example of a configuration in which a separate silencer is mounted on a lower dome connection end having a silencer mounting end (47).

[0079] Here is a description of the device for implementing the present invention:

[0080] Fig. 9 is an example of a module configuration method of the present invention, in which a module of three parts can be implemented.

[0081] As shown in Fig. 9-A, it can be configured as a fixed part in which an upper_top_dome_connection (10) and a middle_top_dome_connection (20) are combined, and as shown in Fig. 9-B, it can be configured as a middle part in which an upper_top_dome_connection and a middle_bottom_dome_connection are combined, and as shown in Fig. 9-C, it can be configured as a middle part in which a lower_dome_connection and a middle_top_dome_connection are combined, so that the user can flexibly configure it by adding or removing the components of Fig. 9-B based on the fixed discharge angle.

[0082] That is, as shown in Fig. 10, Fig. 4, Fig. 5, and Fig. 7, the dome (AA) formed in the middle and the side / rear discharge ports are configured in a variable manner, thereby reducing the recoil and noise of the user's gun (cannon) barrel.

[0083] These variable applications can provide flight stabilization that can increase the velocity and accuracy of the bullet.

[0084] As described above, according to this case, the discharge angle of the discharge port forms a forward angle or a rearward angle based on the center line of the front end from which the discharged gas is discharged, so that the combat participants on the side are not damaged by the gas discharged to the rear, and it includes the characteristics of modular application that can flexibly and variablely apply the characteristics of the gun (cannon) barrel, and it provides the characteristics of greatly improving the re-aiming ability, such as improving the flight stability and accuracy of the flying bullet by inducing gas circulation with the upper and lower semicircular domes formed inside.

[0085] The preferred embodiments of the present invention are provided for illustrative purposes only, and the scope of the present invention is not limited to the specific examples described above. It will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention as defined in the appended claims.
