Description

{SMOKE BOMB FOR PROVIDING BATTLEFIELD EFFECT}

The present invention relates to a smoke bomb that provides a full-field effect, more specifically, a mile system, which is launched through a launcher in the course of advanced simulation training, And the smoke can be made.

In recent years, combat training in military has become more and more advanced by not only simulating a virtual situation but also training a person with a personalization machine to detect the trigger pull and hit, Which enables more realistic simulated combat training.

A system that includes advanced equipment used in these mock combat drills is called the MILES System.

The Miles system is used to determine whether or not to participate in simulated combat by determining whether to fire the laser light instead of the bullet. For example, when a soldier in training enters a target and triggers a trigger on a personalizer or a publicizer, a sensor mounted on the trigger recognizes the trigger pulling, or a sound or light emitted when the loaded blanket or the like is fired is detected by an acoustic sensor The sensor senses and activates the laser launcher attached to the soldier's firearm, from which a pulsed infrared laser is launched to the aimed target. If the fired laser hits all or a portion of a plurality of sensing elements of a sensing device mounted on the outside of a target such as a harness or harness on the helmet and body of each soldier, The signal is converted into an electric signal, and the signal is recognized as a shot signal. The signal is displayed visually and audibly with a warning light mounted on the soldier's body in accordance with the determined logic. At the same time, Ali is configured to send signals to a remote central control system to centrally control the attack.

The martial combat training using the Miles system improves the training effect by providing a battle environment similar to the actual battlefield. In recent years, it is the practice to improve the equipment or add various effects in order to produce a real battle environment. Among them, the way to provide the effect of creating the battle environment is to provide the explosion that occurs when the actual bomb is blown and the smoke explosion due to explosive explosion in the battle place.

Especially in the case of smoke, it is a means of expressing the battle situation from the visual point of view such as covering the clock of the battle place (battlefield) or showing the explosion degree of the bomb.

However, in the case of the presently provided smoke film, it is filled with a smoke film in a container such as a grenade, and the smoke is discharged by firing the smoke film. In most cases, a smoke is generated at the bottom of the electric field, and a shape emitted from a projectile such as a gun And there was a limit to the effect of providing the smoke effect in the area where the actual battle occurred.

Korean Utility Model Opening Public Disclosure 1999-0022207 (published on Jun. 25, 1999) presents a smoke bomb for a weekly event, which has a propellant and a balloon to enable air launch and explosion. However, since the ballast can be fixedly installed on the spot and the firing line is used as a means of ignition, it can be fixedly used only at a predetermined place. Therefore, in the simulated battle training where various places are battle,

The Korean Utility Model Communication Office, 1995-0008733 (published on October 13, 1995), presented the powder tear gas, which was mounted on the tear gas gun and fired. This announcement was installed in the launch gun, which makes it easy to move, so that the tear gas can be sprayed by the launch if necessary. However, according to the structure of the ammunition, the blade is installed at one end of the ammunition box, and when the ignition is performed, the moisture-proof cloth containing the tear powder is discharged from the tank and is torn to spray the tear powder. In other words, this announcement has the advantage of launching while moving, but it does not produce a situation where the blast film is blown up in the air by spraying tear powder at launch.

Accordingly, the smoke bomb, which provides the electric field effect of the present invention,

The purpose of the present invention is to provide a smoke bomb capable of describing a battlefield effect in a battle drill that is launched into the air by a launcher and then formed into a smoke film in the air after a certain period of time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the accompanying drawings. It should be understood, however, that the appended drawings illustrate only the contents and scope of technology of the present invention, and the technical scope of the present invention is not limited thereto. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the technical idea of the present invention based on these examples.

FIG. 1 is a cross-sectional view illustrating a smoke bombarding container according to an embodiment of the present invention, FIG. 2 is a cross-sectional view illustrating a shell of a smoke bombarding container according to an embodiment of the present invention, And FIG. 3B is a plan view showing the AA portion of FIG. 3A showing the mounting state of the cross sectional tube according to the embodiment of the present invention. In the detailed description of the present invention, a portion where a primer is formed is expressed as a lower portion or a lower portion based on a direction shown in the drawing, and a portion where a lid is coupled is expressed as an upper portion or an upper portion.

As shown in the figure, the smoke bomb 10 providing the electric field effect according to the present invention is mounted on the launch device of the Miles device and is launched. The smoke bomb 10 includes a shell 20 containing a propelling charge and a lower packing 30 ), A film forming assembly (40), a top packing (50), and a lid (60) closing the top of the shell.

First, the shell 20 is a cylindrical body having an opened top, a shell body 21 having an inner diameter reduced at an inner lower end thereof and formed with a step 211, and a space inside the shell with the inner diameter of the shell body reduced, And a primer 23 inserted into the through hole communicated from the center of the lower end of the cartridge body to the lower end of the propulsion chamber of the upper portion.

The cap body 21 is a cylindrical body whose lower part is closed, and a hooking protrusion is formed on a lower outer surface thereof to prevent the cartridge body from being moved upward due to a striking force when the ball of the launcher strikes so that a primer ignition is performed.

The propulsion chamber 22 formed by the step 211 is located on the same axis as the shell body 21 and it is preferable to secure a sufficient depth of space so as to stack the propulsion charge that provides the necessary propulsion force . The lower sidewall and the lower bottom of the propulsion chamber 22 are formed to have a greater thickness than the upper sidewall of the casket body so that the explosive force is transmitted to the upper side while preventing the damage due to the propulsion charge explosive force. In addition, since the primer tube 23, the propulsion chamber 22 and the shell body 21 are positioned on the same axis, the flame of the primer ignited by the blow of the launch device is transmitted to the center of the propulsion charge, So that the explosion time of the propulsion charge can be shortened and the explosive force can be cohered and released.

Next, the lower packing 30 is placed on the upper part of the step of the cartridge body.

The lower packing 30 is formed in a disc shape and has a center hole formed therein so that a part of the delay tube 42 of the later-described film forming assembly 40 is inserted. The lower packing 30 functions to prevent breakage of the smoke film assembly due to the pressure applied during the process of inserting or assembling the smoke film assembly into the inside of the shell body. When the explosion of the propellant charge is exerted, Thereby increasing the explosive force transmitted to the smokable agent assembly, thereby increasing the distance the smokable agent assembly can fly.

One of the lower packing 30 may be used alone, or two lower packing 30 may be used, or two or more lower packing 30 may be used. That is, when a propellant charge explosion occurs in the propulsion charge chamber 22, a high-temperature flame is generated, so that if one is used alone, the lower packing may be deformed by heat. Such deformation of the lower packing may occur between the inner surface of the shell body and the lower packing A gap is generated and the explosive force generated by the explosion of the propulsion charge can be dispersed and transferred to the upper part. Therefore, even if the packing close to the propellant charging chamber is deformed into heat, it is possible to prevent the gap from the inner wall of the shell body from being generated by the other packing, so that the explosive force can be transmitted to the uppermost portion through the central through hole.

In addition, the lower packing at the lower end of the lower packing 30, which is close to the propulsion chamber, is made of a material having high insulation performance and the lower packing at the upper end is formed of a material having high hermeticity and elasticity to minimize thermal deformation, .

A film forming assembly (40) is inserted into the shell (20).

The delay pipe 42 is coupled to the lower end of the assembly 40 to delay the transfer of the flame transferred from the propulsion charge to the smoke pipe 45 So that the smoke release time due to smoke film burning is delayed.

The smoke film assemblies 40 include a smoke film cylinder 41 as a cylinder to be inserted into the shell body. The smoke pipe cylinder 41 is formed so that the support inner pipe 411 protrudes in the inner axial direction at the lower center, and the step 412 is formed at the inner face at the upper end of the smoke pipe cylinder, Preferably, the length of the support inner tube is formed to be long enough to support the delay tube inserted through the lower end of the softener tube to prevent deformation of the coupling portion between the delay tube and the softener tube installed on the same axis by the explosive force. Also, the upper bending is performed by bending the upper side wall portion of the softening film cylinder, which is thinned to form a step, to the inner side by 180 degrees so as to prevent the later described detachment of the stopper in the upward direction.

Next, the smoke film assembly includes a delay tube 42 inserted and fixed in the support inner tube 411 of the smoke tube cylinder. As described above, the delay pipe 42 is a pipe that is axially installed in the support inner pipe of the smoke pipe, and a lower end portion of the pipe is coupled to the outside (lower) of the lower end of the smoke pipe. A storage space is formed in the delay tube 42 to fill the retarder 421. A lower end of the delay tube 42 is formed with a through hole 422 communicating between the outside and the internal storage space. The through hole 422 is a path for transferring the propellant flame to the retardant inside the retarder when the propellant ignites by the primer ignition. Therefore, it is preferable that the lower end portion of the through hole 422 exposed to the propulsion chamber 22 is formed in a conical shape with the diameter thereof being opposed to each other in order to facilitate flame penetration of the propellant charge. In addition, it is preferable to protrude a part of the outer surface of the retard tube 42 and to form a groove in the inner surface of the support inner tube to prevent the retard tube from being detached from the support inner tube in the axial direction when the explosive force is transmitted.

A circular plate 43 is placed on the upper end of the support inner tube 411. The drawing plate 43 diffuses the flame by receiving the flame from the delay pipe. The drawing plate 43 is supported by the upper end of the support inner tube at the central portion, and the edge is provided in contact with the inner peripheral surface of the smoke pipe. At this time, protrusions are formed on the inner circumferential surface of the smoke pipe cylinder 41 so as to be horizontal with the upper end surface of the support inner tube, so that support is provided through the center and the edge of the illustrated plate. The drawing board is manufactured from the same material as that of the fuse wire, and may be formed by coating a disk-shaped net with gunpowder.

A lower cushioning material 44 may be installed in the lower space of the drawing plate 43 to fill the space between the outer side of the supporting inner pipe 411 and the inner side of the smoke pipe cylinder 41 as shown in FIG. The lower cushioning material 44 is formed in a donut shape so as to fill the lower space of the drawing plate, so that the explosive force generated in the upper space acts only on the upper part, thereby eliminating the process of filling the lower space of the drawing plate. .

Next, a smoke film 45 is stacked on the upper side of the drawing plate 43. The smoke pipe (45) receives the flame from the drawn plate and burns the flame. The flame is temporarily transferred through the wide face to discharge the large combustion gas and the smoke in a short time.

A disk-shaped wire net 46 is installed on the top of the smoke film. The wire net 46 may restrict the movement of the plasticizer and prevent the flame from being discharged to the outside during the burning of the plasticizer 45, thereby suppressing the occurrence of the surrounding chemicals due to the flame. When the wire net 46 is formed as a single net, a part of the combustion burr may be scattered through the through-hole of the wire net. Therefore, the wire net 46 is composed of a double wire net of the first wire net 461 and the second wire net 462, The separation pipe 463 may be interposed so as to separate the gap. The separation pipe 463 may be formed in a triangular or polygonal shape so as to support the first wire net 461 and the second wire net 462, At this time, as shown in FIG. 3B, each of the vertexes of the separation pipe is disposed so as to be inwardly inwardly of the inner side of the softening agent cylinder 41, thereby restricting the horizontal movement in the horizontal direction with respect to the vertical axis, . When the first wire net 461, the separation pipe 463, and the second wire net 462 are formed, a flame blocking space is secured between the first and second wire nettings, so that the flame partially discharged through the through- It is exposed only to the flame shielding space and can be prevented from being released to the outside by informing the second wire mesh, thereby preventing the risk of fire.

A stopper (47) is coupled to the upper portion of the wire netting to close the upper part of the smoke control cylinder (41). An upper cushion member 48 is inserted into the through-hole to close the stopper. An annular protrusion 471 is formed at the upper end of the outer surface of the stopper, And is prevented from being detached upward by the bending portion at the upper end of the softening pouring cylinder as described above. In this structure, when the internal smoke film is burned and the pressure rises, the stopper blocks the discharge of the wire netting (first and second wire nettings) to the outside, and when the internal pressure is higher than a predetermined pressure, The upper cushion material 48 coupled to the through-hole is pushed to the upper end to communicate with the outside so as to discharge the generated smoke in the combustion.

And a smoke film packing 49 is coupled to the upper portion of the stopper. The softening agent packing hermetically seals the upper end of the softening agent cylinder to prevent moisture absorption.

On the other hand, a disk-shaped upper packing 50 is provided on the upper portion of the cartridge body 21 in which the smoothing assembly 40 constructed as described above is inserted to close the cartridge body while preventing breakage of the smoothing assembly by pressurization .

The upper packing 50 is provided at its upper portion with a lid 60 which is coupled to the upper end of the cartridge body to seal the inside of the cartridge body while pressing the upper packing. The lid 60 may be formed in a cup shape, and an adhesive may be applied to the inner surface of the upper end, and then the lid may be pressed by a punch so that the edge of the lid is in close contact with the inner surface of the upper end of the shell. At this time, it is preferable to use silicone which can improve the hermeticity as the adhesive, and it is possible to use various adhesives capable of maintaining the hermeticity. Further, the lid 60 may be pressed against the upper packing located at the lower side, or may be formed as an annular protrusion protruding downward as shown in the drawing, so that the upper packing is pressed along the edge contacting the upper end of the softening- So that the airtightness can be improved.

The outer diameter of the smoke pipe cylinder 41 is smaller than the outer diameter of the upper portion so that the friction agent resistance due to the contact is reduced during the discharge of the smoke pipe assembly 40 from the shell body 21 to the outside by the propulsion charge explosion. You can.

That is, in the smoke bomb 10 according to the present invention, the smoke assemblies 40 are placed in the shell 20 filled with the propulsion charge, and the smoke assemblies are fired by the explosive force of the propulsion charge. Therefore, since the friction force due to contact with the inner wall of the shell body during the discharge from the shell body 40 is minimized, the propulsion force to be launched can be further improved. Therefore, the outer circumferential surface of the smoke- It is preferable that the change in outer diameter is made small because the outer wall of the softener assembly is irregularly formed in the shell body when the outer diameter is excessively changed. Preferably, the outer surface of the smoke film assembly is formed with a gradient (0 DEG < 1 DEG) within a range of greater than 0 DEG and less than 1 DEG with respect to the axial direction.

Hereinafter, the operation of the present invention will be briefly described.

First, when fired by the launch device of the Miles equipment, the ball of the launcher hits the primer 23 of the smoke charger 10 and is ignited, and the flame of the primer 23 ignites the propulsion charge stacked on the shell. When the gas pressure of the propellant charge acts on the gas pressure of the lid 60 or more, the lid is released and the smoke is discharged from the lid 60, Assembly 40 is fired.

The flame of the propellant charge partially flows into the through hole 422 of the delay pipe 42 to ignite the retarder 421 inside the retard pipe 421. The retarder delays the delivery speed of the flame, (43). The time for delivering the flame of the propellant charge to the plate can be controlled by the length of the delay pipe. Generally, the delay time is about 2 to 3 seconds, so that the smoke container assembly is positioned in the air The flame is transferred to the plate.

The retarder flame transmitted to the drawing plate 43 is diffused in the drawing plate and transferred to the entire lower surface of the smoke film 45. The smoke film having the flame is burned to generate a large amount of gas and smoke. The upper cushioning material 48 inside the top of the top of the top of the top of the top of the top of the top of the top of the top of the top of the top of the top of the top of the top of the top of the top of the top of the top of the top of the top of the top And the release of the smoke is made through the opening.

Therefore, the smoke bomb 10 emitted from the launcher emits smoke in the air after a few seconds, so that the simulated battle drill place can provide an environment similar to a battle battle site, thereby improving the training effect.
