Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tandem warhead warhead to be mounted on a bullet body equipped with equipment in front of a warhead such as a guided bullet having a homing device.

[0002]

2. Description of the Related Art In recent years, as one of the protective measures against anti-tank weapons of tanks, reactive armor (Explosive Rea) is used.
The active armor (ERA) has attracted attention.
ERA is an anti-tank grenade (Hig) that mainly has the Monroe effect (funnel-like filling of the shell with a piercing agent and concentrating the energy of the explosion on the centerline of the funnel hole when landing).
h Explosive Anti-Tank: HEA
It exerts a deterrent against T), and in one example, HE
It has also been reported that 80% of AT's penetration can be reduced.

The basic structure of the ERA is that explosives are sandwiched between two steel plates, and they are provided so that they can be mounted on the surface of the main armor of a tank at a required distance.
The inhibition of the penetration force of ERA against HEAT is performed by scattering the jet generated by the explosion of the warhead by the explosion of the explosive of ERA and the scattering of the steel plate. For the HEAT side, it is the most important issue to deal with ERA against the improvement of protection by mounting ERA on tanks. As a countermeasure against it, tandem warhead (composed of two warheads, subwarhead and main warhead) Is being developed.

The tandem warhead utilizes the disadvantage of ERA that it cannot deal with a two-stage attack. In the case of the ERA detonation method, the steel plate leaves the axis line by detonating the ERA by the jet of the sub-warhead. After that, while the jet of the main warhead advances without being obstructed and penetrates the main armor, in the case of the ERA non-reactive method, the explosive of ERA is scattered by the jet of the warhead and the part where the explosive is lost Since the jet of the main warhead passes, the ERA does not detonate (the ERA becomes ineffective), and the jet of the main warhead penetrates the main armor without being obstructed. Conventionally, as a sub-warhead for this type of tandem warhead, as shown in FIG. 4, while a cylindrical shell 21 is filled with a punch 22 in a funnel shape,
There is known a cylindrical warhead 25 whose surface is covered with a liner 23 and which has an explosive charge 24 attached to the rear end of the shell 21.

As shown in FIG. 5, the cylindrical warhead 25 is appropriately mounted behind a mount 28 such as a guiding device mounted in the front of the bullet 27 of the ATM 26. Then, when the ATM 26 approaches or contacts the reaction armor 31 of the tank, the cylindrical warhead 25 explodes the explosive 22 due to the detonation of the explosive charge 24, and the ERA 31 is inactivated by the jet due to the Monroe effect of the energy of this explosion. The fuse 32 explodes the shell 30 of the main warhead 29, and the jet penetrates the main armor 33.

[0006]

In this conventional tandem warhead warhead, when a tandem warhead is mounted on an ATM, there may be a loading device such as a guiding device in front of the warhead. It is necessary to make the jet powerful enough to neutralize the ERA while being hindered by the guidance device and the like, and the warhead must necessarily have a large caliber. In this way, A
When it is mounted on the TM, the size of the warhead is increased and, as shown in FIG. 6, the layout efficiency in the bullet 27 of the ATM 26 is deteriorated and the dead space 34 is increased. This has an adverse effect on the miniaturization and weight reduction which is constantly required for all flying objects as well as ATM. Therefore, it is an object of the present invention to provide a sub-warhead for a tandem warhead that enhances the efficiency of layout in the bullet body and enables miniaturization.

[0007]

A first tandem warhead warhead of the present invention is a tandem warhead warhead mounted on a bullet equipped with a device in front of the warhead, and has an inner circumference. Alternatively, it is formed in an arc shape or a ring shape along the outer circumference. The second tandem warhead warhead is a tandem warhead warhead that is mounted on a bullet that has a device in front of the warhead, and has an arc shape or ring shape along the inner or outer circumference of the bullet. And is arranged on the outer periphery of a mounting object such as a guiding device mounted in the bullet body. Here, the term "ring-shaped" refers to both a ring that extends along the entire inner or outer circumference of the bullet and a plurality of arc-shaped objects that are appropriately spaced along the inner or outer circumference. .

[0008]

In the first means described above, the dead space generated by the sub-warhead placed inside the ammunition body is reduced.
Further, in the second means, in addition to the same operation as in the first means, the jet of the warhead is not obstructed by the loaded object.

[0009]

Embodiments of the present invention will now be described with reference to the drawings. 1 and 2 are a perspective view of a sub-warhead for a tandem warhead according to one embodiment of the present invention, and a schematic view of a main part of an ATM having the sub-warhead. This warhead 1 is an anti-tank guided bullet (A
TM) 2 is made into an arc shape along the inner circumference of the bullet 3 and A
It has a shell 5 formed in a channel shape that opens to the front of TM2 (the front side in FIGS. 1 and 2), and is arranged around a mounting object 4 such as a guiding device mounted in the shell 3 of the ATM2. is doing. Inside the shell 5, there is formed a V-shaped punch 6 having a middle portion in the width direction as the deepest portion, and a curved surface C.I. Generates a curved jet on S, and AT
The surface of the explosive 6 is filled so as to converge on the jet focal point O on the center line L thereof in front of M2 as appropriate.
Covered by liner 7. An explosive charge 8 is attached to the middle portion of the shell 5 outside the bottom in the width direction.

In the ATM 2 equipped with the warhead 1 having the above structure, the explosive charge 6 is exploded by the detonation of the explosive charge 8, and the detonation wave is generated by the curved surface C.I. Due to the Monroe effect of concentrating on S and converging on the jet focus O, it collides with the ERA of a tank (not shown) located on the jet focus O and E
The RA is incapacitated, and then the main warhead (not shown) of the ATM2 is detonated, and the jet of the main warhead penetrates the main armor without being obstructed by the ERA. Therefore, according to this tandem warhead warhead 1, the dead space 9 in the bullet 3 of the ATM 2 becomes extremely small, as shown in FIG. 3, and the layout efficiency in the ATM 2 becomes very high. When the jet converges on the jet focal point O, the jet is not obstructed by the mounting object 4, and the subwarhead 1 can be downsized.

In the above-described embodiment, the case where the sub-warhead 1 is formed in an arc shape along the inner circumference of the bullet 3 of the ATM 2 has been described, but the present invention is not limited to this and the inside of the bullet 3 is not limited to this. A ring may be formed along the entire circumference or the outer circumference, or a plurality of arc-shaped ones may be arranged in the circumferential direction at appropriate intervals to form a ring shape, which is substantially the same as a single arc-shaped one. The effect is obtained.

[0012]

As described above, according to the first tandem warhead warhead of the present invention, the dead space generated by the warhead placed inside the ammunition body is greatly reduced as compared with the conventional art. The efficiency of internal layout can be significantly improved. In addition, according to the second tandem warhead warhead, in addition to the same effect as the first one, the jet of the warhead is not obstructed by the loaded object, so that the ERA is relatively small. Can be disabled.
