A conventional reactive defense structure (hereinafter, abbreviated as a defense structure) using the energy of an explosive composed of a metal flat plate and an explosive is an explosive cylinder having a conical metal liner (hereinafter, abbreviated as an explosive cylinder). It exerts a very good jet blocking effect on high-speed flow of fluid or powdery metal (hereinafter abbreviated as jet) of metal generated from
It has been reported that the jet blocking effect may be significantly reduced for a composite explosive cartridge that is being developed in recent years. The hybrid defense structure of the present invention not only exerts a jet blocking effect than the conventional defense structure with respect to the conventional explosive cartridge, but also exhibits a high jet blocking effect with respect to the large-diameter composite explosive cartridge. This is a hybrid defense structure that can be obtained.

完成した。FIG. 3 shows a phenomenon when a jet generated from an explosive cartridge collides with the conventional defense structure shown in FIG. That is, when the jet 31 collides with the defense structure, the explosive 22 immediately explodes,
Indicates that the explosive was detonated. 2) The two metal flat plates 21 and 23 start flying at high speed in the normal direction of the metal flat plate surface. As a result of the two metallic flat plates flying at high speed interacting with the jet 35 generated from the explosive cartridge, the penetration capability of the jet is greatly reduced.
However, as described above, this conventional defense structure has a low jet-blocking effect on the composite explosive cartridge. The reason will be described with reference to FIGS. In FIG. 4, a jet 43 generated from the sub-explosive cylinder 42 is applied to a composite explosive cylinder having two explosive cylinders, a main explosive cylinder 41 and a sub-explosive cylinder 42.
Provokes a defensive structure. In addition, pro-explosive cartridge 41
From the jet 44, which impinges on the protective structure, which is virtually impossible to block as shown in FIG. That is, the conventional defense structure cannot exert a good jet blocking effect on a composite explosive cartridge having two explosive cartridges, a main explosive cartridge and a sub-explosive cartridge. The inventors of the present invention have completed the present invention as a result of research for the purpose of developing a device that can obtain a good jet blocking effect for the above-mentioned composite explosive cartridge.

る。FIG. 6 is a view showing an operation of preventing a jet generated from a composite explosive cylinder from colliding with the hybrid defense structure of the present invention. Two sets of conventional defense structures 11, 1 are placed above and below a metal container 15 enclosing a ceramic plate 16.
2, 13; 18, 19, and 20, when the jet 43 generated from the sub-explosive cylinder 42 of the composite explosive cylinder enters the defense structure, the ceramic plate 1
The ceramic plate enclosed in the metal container prevents the jet 43 generated from the sub-explosive cylinder from penetrating even if the explosive of the defense structure disposed above the metal container 15 in which the internal explosive 6 is enclosed. Jets generated from
The detonation and deformation of the defense structure arranged at the lower part of the metal container enclosing the ceramics plate did not occur, and the pro-explosive cartridge 4 continued.
Even if the jet generated from 1 is incident on the defense structure located below the metal container enclosing the ceramic plate, the penetration capability of the jet generated from the pro-explosive cartridge is arranged below the metal container enclosing the ceramic plate. Since it can be blocked by the structure, the hybrid defense structure of the present invention exerts a good jet blocking effect on a composite explosive cartridge having two explosive cartridges, a main explosive cartridge and a sub-explosive cartridge.
Also, for the conventional explosive cylinder, the penetration capability of the tip of the jet generated from the explosive cylinder, which cannot be prevented by the conventional defensive structure, is based on the defensive structure arranged at the top of the metal container enclosing the ceramic plate and Since the ceramic plate enclosed in the metal container is greatly reduced, a jet blocking effect higher than that of the conventional defense structure can be exhibited as a whole.
