DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reactive defense structure (hereinafter, abbreviated as a defense structure) utilizing the energy of an explosive energy material such as an explosive.

[0002]

2. Description of the Related Art As shown in FIG. 4, a conventional defense structure has a structure in which an explosive or other explosive energy substance 22 is filled between two metal flat plates 21 and 23. As shown in FIG.

[0003] A conventional defense structure composed of a metal flat plate and an energy material is a metal fluid or powder generated from an explosive cylinder having a conical metal liner (hereinafter abbreviated as an explosive cylinder). It exerts a very good abatement effect (hereinafter abbreviated as a jet abatement effect) against a high-speed flow of metal (hereinafter abbreviated as a jet). Since the angle of incidence, that is, the angle of attack, which is the angle between the jet generated from the explosive cylinder and the normal of the metal plate surface of the defense structure, greatly depends on the jet generated from the explosive cylinder, In the event of an incident, the jet-attenuating effect of the capability of the jet generated from the explosive cartridge by the defensive structure is significantly reduced. Also, when the defense structure mounted on various vehicles, etc. exerts its function by the explosive cylinder, the metal plate of the defense structure on the side close to the outer plate of the vehicle collides with the outer plate of the vehicle at high speed. There is a possibility that the outer panel of a vehicle or the like may be damaged by spalling.

[0004]

FIGS. 5 to 7 are diagrams for explaining the operation of the conventional protective structure, and the problems of the conventional protective structure will be specifically described. When the jet 31 generated from the explosive cylinder collides with the conventional defense structure, the energy substance 22 reacts quickly and the two metal flat plates 2
Nos. 1 and 23 start flying at a high speed in the direction of the normal to the flat metal surface. As shown in FIG. 5, the two metal plates flying at high speed mutually interfere with the jet generated from the explosive cartridge, and as a result, the capability of the jet is greatly reduced. Numeral 32 denotes a jet generated from an explosive cartridge that has lost its ability due to interference with a metal flat plate. However, as is apparent from this jet abatement mechanism, in the conventional defense structure, as shown in FIG. 6, when the jet generated from the explosive cartridge enters the defense structure at a small angle of attack, the metal plate 21 of the defense structure is not used. And 23, it is difficult to reduce the capability of the jet 31 generated from the explosive cartridge, and there is a drawback that it is hardly expected to exhibit a good jet attenuating effect. Further, when the defense structure mounted on various vehicles and the like exerts its function by the explosive cylinder, the metal plate 23 on the side closer to the outer plate of the vehicle among the metal plates of the defense structure flying at high speed. But at high speed
7, there is a possibility that the outer plate of the vehicle or the like suffers damage such as spall destruction (destruction pieces 54 and 55) as shown in FIG. The parallel flying eccentric protection structure of the present invention has been completed as a result of various improvements in view of the various drawbacks of the conventional protection structure in which an energy substance is sandwiched between two metal flat plates. Things.

That is, the parallel flight type eccentric protection structure of the present invention has a higher jet attenuating effect than the conventional protection structure without depending on the angle at which the jet generated from the explosive cartridge enters the parallel flight type eccentric protection structure. Not only the defensive structure that can demonstrate the effect, but also the parallel flying type eccentric defense structure mounted on various vehicles, etc., when the function is demonstrated by the explosive cartridge, the parallel flying type eccentric protection that flies at high speed It is an object of the present invention to provide a defense structure for reducing damage such as spall breakage of an outer plate of a vehicle or the like by a metal plate on the side close to the outer plate of the vehicle or the like having a structure.

[0006]

As shown in the embodiment of FIG. 1, the parallel flying type eccentric protection structure of the present invention has an explosive energy such as an explosive between two metal plates 11 and 13. In a reactive defense structure having a structure filled with a substance 12, the two metal plates 11, 13 have a shape in which the thickness is inclined from the one end surface to the other end surface. And one metal plate 11 and the other metal plate 1
3 is characterized in that the direction of the change in the thickness is made the opposite direction. That is, the energy material 12 is filled between two metal plates 11 and 13 having asymmetric thicknesses.

[0007]

[Function] The jet generated from the explosive cartridge is the parallel flight of the present invention by making the structure of the parallel flight type eccentric protection structure a structure in which energy material is filled between two asymmetric metal plates. As shown in FIG. 2, even when the metal plates 11 and
3 does not fly in the direction of the normal of the metal plate surface but makes a parallel type eccentric flight, so the parallel type eccentric metal plate and the jet generated from the explosive cylinder cause mutual interference. As a result, the ability of the jet is greatly reduced, so that it is possible to exhibit the jet reducing effect as a defense structure. In other words, when the jet generated from the explosive cartridge enters the defense structure at a small angle of attack, the conventional defense structure could not be expected to reduce the ability of the jet, but with the parallel flying eccentric protection structure of the present invention Since it can be attenuated, it is possible to exert a jet attenuating effect more than the conventional defense structure as a whole. Further, when the parallel flying type eccentric protection structure of the present invention mounted on various vehicles and the like exerts its function by the explosive cylinder, the metal plates 11 and 13 fly in the normal direction of the metal plate surface. Among the metal plates of the parallel flying type eccentric protection structure which flies at high speed in order to make a parallel type eccentric flying, the metal plate 13 on the side close to the outer plate of the vehicle etc. is the outer plate of the vehicle etc. Since the collision occurs while gradually contacting the outer surface 53, there is no possibility that the outer plate is damaged by spalling or the like as shown in FIG.

[0008]

1 shows an embodiment of a parallel flying type eccentricity prevention structure according to the present invention. The metal plates 11 and 13 constituting the parallel flying type eccentric protection structure include iron-type materials such as high-strength steel, ultra-high-strength steel, and bullet-proof steel or aluminum alloys.
A light metal material such as a titanium alloy is used. The thickness of the metal plate varies depending on the caliber, liner shape, etc. of the target explosive cylinder, but the thickness of the thinner side is in the range of 2 to 5 mm, and the thickness of the thicker side is 4 to 5 mm. A range of 10 mm is appropriate.
Then, the thinner side of one metal plate 11 and the thicker side of the other metal plate 13 are set to the same side. The energy substance 12 uses a PBX-type high explosive low-fire sensitivity explosive or the like,
The thickness of the energy material is suitably in the range of 3 to 10 mm depending on the diameter of the target explosive cylinder, the shape of the liner, and the like.

The shape and dimensions of the structure of the present invention are as follows.
The design can be made as appropriate according to the type of the vehicle to be mounted, the site to be mounted, particularly the inclination angle and the type of the target explosive cylinder.

[0010]

The parallel flying type eccentric protection structure of the present invention is a structure in which an energy substance is filled between two asymmetric metal plates. In the conventional protection structure, a jet generated from an explosive cylinder is used. Could not be expected to reduce the jet's ability if it hit the defense structure at a small angle of attack, but with the parallel flying eccentric protection structure of the present invention, the jet generated from the explosive cylinder parallelized at a small angle of attack. Even if it is incident on the flying-type eccentric protection structure, the metal plate does not fly in the normal direction of the metal plate surface but makes a parallel-type eccentric flying. Jets generated from the plate making and the explosive cartridge cause mutual interference, and as a result, the ability of the jet is greatly reduced, so that the jet can be reduced as a defense structure. Furthermore, when the parallel flying type eccentric protection structure of the present invention mounted on various vehicles, etc. exerts its function by the explosive cylinder, the metal plate does not fly in the normal direction of the metal plate surface. Among the metal plates of the parallel flying type eccentric protection structure that fly at high speed to make the mold eccentric flying, the metal plate near the outer plate of the vehicle etc. gradually contacts the outer plate of the vehicle etc. Since the vehicle collides with the vehicle, there is no possibility that the outer panel of the vehicle or the like is damaged by spall. As described above, the parallel flight type eccentricity prevention structure of the present invention is a parallel flight type eccentricity which flies at a high speed when the protection function of the outer plate of various vehicles and the like and the parallel flight type eccentricity protection structure functions. Among the metal plates of the defense structure, the metal plate on the side closer to the outer plate of the vehicle or the like is highly useful in reducing damage to the outer plate of the vehicle or the like.
