BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the reaction of water and a substance to be reacted in a container to generate acetylene gas or hydrogen gas, and to spray a reaction product of the acetylene gas or hydrogen gas and an oxidizing agent.

2. Description of the Related Art A conventional mobile charge electrothermal chemical bomb and its launching device are known from Japanese Patent Publication No. 7-39919. The electrothermal chemical ammunition includes water provided in a container, a plurality of aluminum bodies provided in the water, and a bullet held in the container, so that the aluminum body can be energized. Features. Then, when a current is supplied to the aluminum body, the current rises according to the time constant of the aluminum body, reaches a predetermined high temperature (about 600 ° C.), and water and the aluminum body start an explosive chemical reaction, Generates hot hydrogen gas and fires a bullet. At the same time, the charge of the bullet is pyrolyzed by the high-temperature hydrogen gas, and the bullet is fired at high speed.

[0003]

However, such a conventional mobile charge electrothermal chemical bomb and its launching apparatus have the following technical problems. That is, in the case of the conventional electrothermal chemical ammunition, the main reactants are water and an aluminum body, which depends on the oxidation reaction of aluminum, so that a relatively large amount of hard aluminum oxide is generated together with high-temperature hydrogen gas. However, this aluminum oxide penetrates into the gun cavity and adheres to the gun cavity, thereby hindering the acceleration of bullets to be fired thereafter. For this reason, it is necessary to provide a separating device for preventing the hard aluminum oxide from entering the gun cavity. As an electrothermal chemical bomb provided with this type of separation device, there has been proposed an electrothermal chemical bomb which applies a cyclone to separate solid fine particles by centrifugal force (for example, Japanese Patent Laid-Open No. 5-22).
No. 3497). However, since this solid particulate separation device needs to form a large-volume space near the container, the energy density generated in the vicinity of the container as a cartridge case is reduced overall, and as a result, the electrothermal chemical bomb and its The miniaturization of the launching device is hindered.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of a transfer charge electrothermal chemical ammunition according to the present invention. In the drawing, reference numeral 60 denotes a moving charge electrothermal chemical bullet, and the moving charge electrothermal chemical bullet 60 has a cylindrical container 10 made of an electrical insulator. One end 10a of the container 10 has a current introduction terminal 1
1 is provided by screwing, and a power supply (not shown) is connected to the current introduction terminal 11. A metallic tubular connector 12 is screwed to the other end 10b of the container 10.

[0006] A disk-shaped partition member 13 formed of a conductive material (eg, aluminum) is provided between the connector 12 and the container 10 so as to maintain liquid tightness in the container 10. The current introduction terminal 11 and the partition member 13 face each other in the cavity 10 c of the container 10. This container 1
A reactant 21 made of calcium carbide (CaC ₂ ) is liquid-tightly partitioned by a cylindrical partition wall 20 at the outer peripheral portion of the hollow portion 10c. The partition 20 is made of a material or a thickness which is more easily broken by the action of heat or external force than the partition member 13. And the partition 2

Is contained.

FIG. 2 shows a launching apparatus equipped with a moving charge electrothermal chemical bullet 60. The moving charge electrothermal chemical ammunition 60 is provided in close contact with the base of the barrel 51a of the barrel 51 having a cylindrical shape. A terminal 52 and a stator 53 are provided on a breech 51 b of the barrel 51. The terminal 52 is electrically connected to the partition member 13, and the stator 53 is directly connected to the current introduction terminal 11. The power supply 55 is connected to the stator 5 via the switch 2.
3 and to a terminal 52.

When the switch 2 is turned on and a current is applied to the heating wire 4 from the current introduction terminal 11, the heating wire 4 is heated and the water 14 is heated to a high temperature by Joule heat, and at the same time, the pressure in the vessel 10 is increased. Becomes Also, a strong shock wave runs in the water 14, and the partition wall 20 is broken by the shock wave, pressure or heat. As a result, the high-temperature water 14 and the reactant 21 composed of calcium carbide are rapidly mixed, and acetylene gas (C ₂ H ₂ ), which is a high-temperature combustible gas, is generated by the reaction shown in Chemical formula 1, and Since the pressure in 10 further increases, the partition member 13 is deformed by being deformed toward the bullet bottom of the bullet 15. A large amount of the oxidizing agent 22 is sealed between the partition member 13 and the bullet 15, and the burst of the partition member 13 accelerates the bullet 15 together with the oxidizing agent 22, and at the same time, acetylene gas which is a high-temperature combustible gas. (C ₂ H ₂ ) heats and ignites the oxidizing agent 22 and is injected at an extremely high pressure, causing the bullet 15 to undergo a high acceleration.

High-pressure reaction products generated by combustion of acetylene gas and the like, for example, water, carbon dioxide gas, potassium chloride, etc., are injected backward, and the bullet 15 is formed by the oxidizing agent 22 functioning as a moving charge. It accelerates like a rocket and reaches high speed. Therefore, by appropriately selecting the power supply 55, the resistance value of the heating wire 4, the amount of the reactant, etc.,
The pressure of the gas acting on 5 can be maintained for a predetermined time, and the bullet 15 is fired at high speed from the muzzle 51 c of the barrel 51.

Calcium hydroxide (Ca (OH) ₂ ) generated by the reaction between the high-temperature water 14 and the reactant 21 composed of calcium carbide has a high fluidity, so that the gun cavity 51 is formed.
Even if it leaks into a, it does not become a big obstacle to the passage of the next bullet. For this reason, the firing device can be easily fired. The heating wire 4 has only to have a function of heating the water 14 to a high temperature and breaking the partition wall 20 by a shock wave, pressure or heat, and the material thereof is not particularly limited. Therefore, even when the heating wire 4 is formed of aluminum, it is not necessary to actively cause an oxidation reaction in aluminum, and the generation of hard aluminum oxide is limited to a small amount that does not cause a practical problem. be able to.

By the way, in place of the reactant 21 made of calcium carbide, a partition wall 20 is used to partition the outer periphery of the hollow portion 10c of the container 10 in a liquid-tight manner, thereby forming a simple substance of alkali metal such as metallic calcium and sodium. Alternatively, a mixture thereof can be arranged. At least one of the alkali metals such as calcium or sodium metal
The reactant substance 21 consisting of a seed produces a reaction product containing hydrogen in the reaction with the water 14. These reaction products are rich in fluidity and have such a property that even if they are fixed in the gun cavity 51a, they do not obstruct the passage of the next round. For example, when the substance to be reacted 21 is sodium, a reaction shown in Chemical formula 2 occurs with the water 14. Therefore, if the Joule heat is given by the action of the heating wire 4 in the water 14 and rapid mixing is performed, high-pressure hydrogen is generated. And
A reaction product of the oxidizing agent 22 and hydrogen gas is injected while accelerating a bullet 15 on which an oxidizing agent 22 such as ammonium nitrate or potassium perchlorate is attached to the bullet. Accordingly, it is possible to give the bullet 15 a high speed, and it is possible to obtain substantially the same operation as in the first embodiment.

As will be understood from the above description,
ADVANTAGE OF THE INVENTION According to the mobile charge electrothermal chemical bomb and its launching apparatus which concern on this invention, the following effects can be produced. That is, since the main reactant was water and a substance to be reacted consisting of at least one of alkali metals such as calcium or metallic calcium and sodium, sodium and the like, and the reaction product was selected so as to be rich in fluidity, The reaction product was prevented from adhering to the gun cavity of the barrel and hindering the flight of the bullet. As a result, there is no need to attach a reaction product separation device, the structure is simplified, and a decrease in energy density generated in a container as a cartridge case can be prevented. The device can be miniaturized.
