2. Description of the Related Art As shown in FIG. 2, a conventional defense structure has an energy substance 2 between two metal flat plates 21 and 23. As shown in FIG.
2 is filled. Thus, the metal flat plate 21,
The conventional defense structure including the energy substance 23 and the energy material 22 is a high-speed liquid metal or powder metal generated from an explosive cylinder having a conventional conical metal liner (hereinafter abbreviated as an explosive cylinder). It has a very good abatement effect (hereinafter abbreviated as a jet abatement effect) against the flow (hereinafter abbreviated as a jet). In other words, since it greatly depends on the angle of attack, which is the angle between the jet generated from the explosive cylinder and the normal to the flat metal surface of the defense structure,
When the jet generated from the explosive cylinder enters the defensive structure at a small angle of attack, the jet-causing effect of the jet generated from the explosive cylinder by the defensive structure is significantly reduced. In addition, when the defense structure mounted on various vehicles, etc. exerts its function by the explosive cylinder, the metal flat 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 a high speed, There is a possibility that the outer panel of a vehicle or the like may be damaged by spalls.

When the jet 31 generated from the explosive cartridge collides with the conventional defense structure, the energy substance 22 reacts promptly as shown in FIG. 3, and the two metal flat plates 21 and 23 are separated. Start flying at high speed in the direction normal to the flat metal surface. As shown in FIG. 3, the two metal plates flying at a high speed interact with the jet generated from the explosive cartridge, and as a result, the capability of the jet 32 is greatly reduced. However, as apparent from this jet abatement mechanism, in the structure of the conventional defense structure, FIG.
As shown in the figure, when the jet 31 generated from the explosive cylinder enters the defense structure at a small angle of attack, the jets 3 generated from the explosive cylinder are formed by the metal flat plates 21 and 23 of the defense structure.
However, there is a drawback that it is difficult to reduce the performance of No. 1 and it is hardly expected to exhibit a good jet reducing 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. However, since it collides with the outer plate 41 of the vehicle or the like at a high speed, there is a possibility that the outer plate of the vehicle or the like suffers damages 51 and 52 such as spall destruction as shown in FIG.

The opening eccentric flying type reactive defense system according to the present invention
In the structure, by using a structure in which energetic material of asymmetric thickness is filled between two metal plates of asymmetric thickness,
As shown in FIG. 6, the jet 31 generated from the explosive tube
Even when incident at small a撃角, since the metal plates 11 and 13 is in the normal direction of the metal plate surface to the eccentric flight of gated without flight, the eccentric flight of the opening type metal plates 11 and 13 and the jet 31 generated from explosives barrel interfere with each other, the resulting ability of the jet 31 32
As shown in (1), it is possible to exert a jet abatement effect as a defense structure. That is, when the jet 31 generated from the explosive tube is incident at a small撃角reactive defense structures <br/>, in the conventional protective structure, but it could not be expected to diminish the ability of the jet, the aperture of the present invention Since the eccentric flying type reactive defense structure can attenuate the jet, the overall effect of the jet can be reduced as compared with the conventional defense structure. Furthermore, the aperture eccentric flying type reactive protection of the present invention mounted on various vehicles, etc.
Fig. 7 shows the structure when the function was demonstrated by the explosive cartridge.
As shown in the figure, since the metal plates 11 and 13 do not fly in the normal direction of the surface of the metal plate and make an open type eccentric flight, the open eccentric flying type reactive defense which flies at a high speed.
Among the metal plates of the structure, the metal plate 13 on the side close to the outer plate of the vehicle or the like collides while gradually contacting the outer plate 41 of the vehicle or the like, so that the outer plate 41 may be damaged by spall destruction or the like. Sex disappears.
