Description

[Detailed description of the invention]

[Industrial Field of Application] The present invention relates to a warhead disposal tool, and more specifically, for example, warheads of unusable artillery shells, missiles, etc., and unexploded ordnance generated during exercises, etc. (hereinafter referred to as target munitions). ) when disposing of, etc.
The present invention relates to a warhead disposal tool that enables safe combustion of these target bullets without causing them to explode. [Prior art and its problems] Conventionally, target bullets have been disposed of by transporting them far out to sea and dumping them into the sea, or by attaching the required amount of explosives to the target bullet depending on the type of bullet and then remotely disposing of it. It depends on one of the detonation processes that detonate the explosives. In any case, the current situation is that when disposing of target bullets, a great deal of effort and expense is spent on safely transporting the target bullets, evacuation of surrounding residents, safety measures for disposal workers, etc. This invention has been made based on the above circumstances. That is, an object of the present invention is to provide a warhead disposal tool with a simple structure that can safely neutralize target bullets at the site without transporting them. [Means for achieving the above object] The outline of this invention for achieving the above object is as follows:
A base having a curved surface that can be brought into close contact with the circumferential side of the warhead body is attached to an opening at one end of a cylinder made of a non-combustible material, and a metal melting agent and an ignition device for igniting the metal melt are loaded into the cylinder. The explosive inside the warhead is burnt by rapidly and intensively heating the body of the warhead that is in close contact with the curved surface of the base with high heat generated by burning the metal melting agent by the ignition device. It is a warhead disposal tool. Next, the configuration of the present invention will be explained in detail with reference to the drawings. As shown in FIG. 1, in this warhead disposal tool 1, a base 3 is attached to an opening at one end of a cylindrical body 2 made of a noncombustible material. The cylindrical body 2 may be a cylindrical body or a rectangular cylindrical body, but in consideration of ease of processing, a cylindrical body is preferable. Further, the material for forming the cylinder 2 is not particularly limited as long as it is a noncombustible material, and for example, it can be suitably formed from flame retardant synthetic rubber, asbestos, or the like. As shown in FIG. 1, the base 3 is formed of a plate-like member having a curved surface 5 that follows the circumferential surface of the body of the warhead 4.
Any shape may be used as long as it can be supported by the warhead 4 and closely attached to the body of the warhead 4. For example, the third
As shown in the figures and FIG. 4, one surface of the rectangular box body 6 is formed into a concave curved surface 5 that follows the circumferential surface of the warhead body, and a flat section 7 opposite to the curved surface 5 has a cylinder. It may be configured to support the body 2.
However, considering the ease of machining of the cylinder 2, the base 3 has a concave curved surface 5 that follows the circumferential side of the warhead body.
and has a flat part 7 on the opposite side to the curved surface 5,
For example, the box shape shown in FIGS. 3 and 4 is preferable. The material of the base 3 is not particularly limited as long as it supports the cylindrical body 2 and can be melted by the metal melting agent 8 described later. For example, the base 3 may be made of metal, rubber, synthetic resin, or the like. It is usually made of synthetic rubber mixed with flame retardants. Further, the curvature of the curved surface 5 of the base 3 is determined according to the curvature of the circumferential side of the warhead body.
Needless to say. The cylindrical body 2 may be inseparably connected to the base 3 by an appropriate means, but as shown in FIGS. An annular frame 9 is formed upright on the side plane part 7, and one end of the cylinder 2 is fitted into the annular frame 9, thereby separating the base 3 and the cylinder 2. It is preferable that the device be configured so that it can be attached. This is because the warheads 4 have various diameters, and in order to make the warhead processing tool 1 compatible with various warheads 4, it is necessary to attach the cylinders to the base 3 having curved surfaces 5 of various curvatures. It is necessary to prepare a warhead disposal tool 1 equipped with a body 2. Therefore, by making it possible to attach the base 3 and the cylinder body 2 in a separable manner, by simply attaching one kind of cylinder body 2 to each type of base 3, warheads corresponding to various warheads 4 can be attached. This is because it is extremely economical since it can be used as a processing tool 1, and it is also convenient to accumulate and store this type of warhead processing tool 1.
Furthermore, by forming the frame, when the metal melting agent is a thermite agent, it is possible to prevent the molten iron produced by the combustion of the metal melting agent from flowing out to the circumferential side of the warhead, This is because it can centrally heat the bullet shell directly below the body. This base 3 is preferably provided with a fixing means so that it can be securely fixed to the warhead body. As this fixing means, for example, the concave curved surface 5 of the base 3
An adhesive or adhesive may be applied to the base 3, or one or more magnets 10 may be embedded within the concave curved surface 5 of the base 3, as shown in FIG. 5, for example. However, the use of the magnet 10 is limited to cases where the bullet shell of the warhead 4 is made of a magnetic material such as steel. Further, as the fixing means, as shown in FIGS. 3 and 4, at least a pair of elastic plate-like members 11, such as steel plates, are attached to the side surfaces of the base 3, and the warhead body is fixed with these plate-like members 11. It may be constructed so that it can be held in place. The plate member 11 is a universally applicable and convenient fixing means regardless of the material of the bullet shell. A metal melting agent 8 and an ignition device 12 for igniting the metal melting agent 8 are loaded into the cylindrical body 2 supported by the base 3. As the metal melting agent 8, for example, a mixture of aluminum and a metal oxide can be used, and a mixture of aluminum and iron oxide called a thermite agent is particularly preferred. This is because the oxidation heat of aluminum generates high heat, this high heat reduces iron oxide to produce molten pure iron, and the high heat of molten pure iron melts the shell and opens it. This is because it is suitable for not only penetrating the warhead but also burning the explosive inside the warhead. The metal melting agent 8 may be directly filled into the cylindrical body 2 as shown in FIG. This makes it easier to manufacture the warhead processing tool 1. In this case, the cylindrical container is preferably a metal container having approximately the same diameter as the inner periphery of the cylindrical body 2. The ignition device 12 includes a transfer charge 14 and an ignition charge 15 in a cylindrical case 13, as shown in FIG.
A fireball 17 filled with and having a leg line 16
is embedded in the ignition powder 15 and the ignition ball 17 is ignited by passing a current through the leg wire 16, thereby causing the ignition powder 15 and the transfer powder 1 to ignite.
4 are sequentially ignited, and the metal melting agent 8
Insert and place inside. Only one igniter 12 may be inserted into the metal melt 8, but in order to reliably ignite the metal melt 8, a plurality of igniters 12, for example two igniters 12, are inserted into the metal melt 8. is preferable. [Operation] Next, the operation of the above configuration will be explained. To explain the warhead processing tool 1 shown in FIGS. 1 and 2, first, a base 3 is attached to the circumferential side of the warhead body.
Apply the concave curved surface 5. Next, leg line 16
A current is passed through. Note that if the leg line 16 is extended for a long time, the ignition operation can be performed from a remote location, so that the warhead 4 can be safely neutralized. When a current is passed through the leg wire 16, the ignition ball 17
ignites, which causes ignition powder 15 and transfer powder 1
4 are ignited in sequence, and the metal melting agent 8 is ignited. When the metal melting agent 8 is ignited, the high heat generated thereby concentrates on the shell, melting the shell and opening the shell, and burning the explosive inside the warhead. In particular, when the metal melting agent 8 is a thermite agent that is a mixture of aluminum and iron oxide, the iron oxide is reduced by the high heat generated by the oxidation of aluminum and pure iron in a molten state is produced. Pure iron flows downward inside the cylinder 2, and the molten pure iron that reaches the bottom of the cylinder 2 melts a part of the base 3 due to its high heat, and eventually melts the bullet shell as well. Become. At the same time as the bullet shell melts and opens, the explosive inside the warhead 4 also begins to burn due to this high heat. At this time, since the shell has been opened, the explosive does not cause detonation, but only mild combustion. Additionally, when the bullet shell is thick, the explosive inside the warhead may ignite before the shell is opened by the molten iron.
At this time, the bullet shell is weakened by the high heat, and the gas pressure generated by the ignition of the explosive causes it to crack. In this way, when using thermite agent as the metal melting agent 8, the cylindrical body 2
It is preferable to place the warhead processing tool 1 so that the warhead is vertical. In addition, since the cylinder body 2 of this warhead disposal tool 1 is made of non-combustible material, the metal melting agent 8, which generates high heat and burns, will not be scattered around, so that the warhead 4 can be neutralized. Extremely safe. [Example] Next, an example of the present invention will be described with reference to the drawings. FIG. 6 is a partially cutaway perspective view showing an embodiment of the present invention. This warhead processing tool 20 has a lower surface portion formed on a curved surface 21 having a curvature that follows the circumferential surface of the warhead, an upper surface portion 22 formed as a flat surface, and an annular frame 23 approximately in the center of the upper surface portion 22. Base 2 to be erected
4, a bottom plate 25 is fitted into the lower end opening to form a bottom part, and a metal container 27 filled with a thermite agent as a metal melting agent 26 is housed therein, and the metal container 27 can be fitted into the annular frame 23. A cylindrical body 28 having an outer diameter and made of a noncombustible material such as asbestos and having a bottom fitted into the frame 23 is provided, and a lid plate 29 is placed on the upper opening of the metal container 27. An ignition device 34 containing a ignition ball 31 that hides the thermite agent and connects a long drawn-out leg line 30, an ignition charge 32 in which the ignition ball 31 is embedded, and a transfer charge 33 is housed in a cylindrical case. The plate 29 is inserted into the thermite agent through the ring, and the base 24 is inserted into the thermite agent.
A pair of elastic bands 36, which serve as fixing means, are provided as fixing means, each having a clamping portion 35 that faces each other at an interval slightly smaller than the diameter of the warhead and is curved outward so that the tips thereof are separated from each other. Frame body 23
The base 24 is arranged and fixed so as to sit astride the base 24 with the base 24 in between. Although not shown in FIG. 5, an outer cover is attached to the upper opening of the cylindrical body 28 in order to prevent the thermite agent from absorbing moisture during storage. The warhead processing tool 20 configured as described above operates as follows. That is, the base 24 of the warhead processing tool 20 with the curved surface 21 facing down is attached from above to the body of a warhead that is laid down so that its axis is substantially horizontal. In the attached state, the curved surface 21 of the base 24
is in close contact with the circumferential side of the body of the warhead, and the pair of clamping parts 35 of the elastic band 36 clamps the body,
The entire warhead processing tool 20 is mounted so as to sit astride the warhead body. In addition, when installing, the said clamping part 3
Since the ends of the elastic bands 36 are curved so as to separate from each other, the elastic bands 36 can easily hold the body. Next, the leg wire 30 is pulled out to a safe zone and connected to a power source. At this time,
Since the neutralization process of the warhead by the warhead disposal tool 20 does not involve detonation, it is sufficient to be at a distance of several tens of meters from the warhead even if it is called a safe zone.
When the ignition ball 31 is energized from the power supply via the leg wire 30, the ignition charge 32 and the transfer charge 33 are ignited in sequence by the ignition of the ignition ball 31, and then the metal melting agent 26 is ignited. When the metal melting agent 26 burns,
The high heat generated by the oxidation of aluminum reduces the iron oxide and generates molten iron, which falls to the bottom of the cylindrical body 28, and the high heat of the molten iron damages the bottom plate 25 and the metal container. The base 24 is melted, and finally the shell of the warhead is melted and opened. At the same time as the bullet shell melts and opens, the explosives inside the warhead ignite due to the high heat. At this time, the shell of the warhead is in an open state, so even if the explosive is ignited, it will only begin to burn gently without causing a detonation. Also, the metal melting agent 2 is inside the cylinder body 28.
6 is burning, the cylindrical body 28 is made of a non-combustible material, so the burning metal melting agent 26 does not scatter horizontally around the cylindrical body 28.
It will be concentrated at the bottom. However, cylindrical body 2
Although the burning metal melting agent 26 may fly out from the upper opening of the opening 8, the extent of this is small. Once all the explosives in the warhead have been burned, the process of neutralizing the warhead is complete. In addition, sometimes the warhead partially explodes, but it never completely explodes.
The fragments of the shell will only burst into a few pieces at most, and the scattering distance will be about 3 to 40 meters. Next, Table 1 shows various doses of thermite agents (aluminum powder 76% by weight, aluminum powder 76% by weight,
The first example shows the specific processing time and the combustion state of the explosives in the warhead when various warheads are neutralized using the warhead processing tool 20 using a mixture containing 24% iron oxide (a mixture of 24% by weight of iron oxide).
Shown in the table.

[Table] [Effects of the Invention] According to this invention, a metal melting agent is burned in a cylinder made of non-combustible material, and the shell of a warhead is rapidly and intensively heated by the high heat generated by the combustion of the metal melting agent. The explosive inside the warhead is combusted, and the combustion gas of the explosive is discharged from the hole in the shell or the weakened part of the shell that has been melted and opened by the high heat.
To safely neutralize a warhead at the site without detonating it at the site, without risking transporting the warhead to a remote location, and without scattering the metal melting agent burning in the cylinder to the surroundings. It is possible to provide a warhead processing tool with a simple configuration that can perform the following operations.
