DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to the detailed description of the present invention, terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary terms. Therefore, the embodiments described in this specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, It is to be understood that equivalents and modifications are possible.

FIG. 1 is a cross-sectional view showing an embodiment of an improved warhead according to the present invention. Referring to FIG. 1, the improved warhead according to the present invention includes a warhead body having a gunpowder space therein, The member (100) includes a decanter member (200) filled in the explosive space of the warhead body member (100) and containing a gunpowder and being detonated by a fuse.

Peak member 200 can be explosive when the gun shell reaches the target point at the target point or at a predetermined time by the fuse containing high explosives such as RDX, HMX, TNT and the like.

The peeling member 200 includes a first peeling unit 210 including a high explosive such as RDX, HMX and TNT formed in the longitudinal direction of the warhead body member 100 and a first peeling unit 210 covering the first peeling unit 210, , TNT, and the like.

The first decanter 210 and the second decanter 220 may have at least two characteristics of a gunpowder composition having different compositions, such as a storm effect, a debris effect, and a warhead characteristic.

In more detail, the first decanter 210 includes any one of RDX, HMX, and TNT, a high explosive, metal particles, and a binder. Also, the second contractor 220 may include any one of RDX, HMX, and TNT as a high explosive and a binder.

More specifically, the first decanter 210 comprises 30 to 70% by weight of the high explosive powder, 20 to 60% by weight of the metal particles and 10 to 30% by weight of the binder, and the second decanter 220 comprises the high- By weight, and 10 to 30% by weight of a binder.

The metal particles may be selected from the group consisting of aluminum powder, magnesium powder, boron powder, molybdenum powder, zirconium powder, titanium powder, nickel powder, tungsten powder, aluminum / magnesium alloy powder, aluminum / nickel alloy powder or aluminum powder, magnesium powder, , Zirconium powder, titanium powder, nickel powder, tungsten powder, aluminum / magnesium alloy powder, and aluminum / nickel alloy powder.

Also, the high explosives may be selected from the group consisting of petitne (PETN), hexogen (RDX), octogen (HMX), nitrocellulose and nitroguanidine, hexanitrohexaazaisowurtzitane (HNIW) 1,2,4-triazol-5-one (NTO), 1,1-diamino-2,2-dinitroethylene (DADNE) and 3-nitro- Lt; / RTI >

The binder may be selected from the group consisting of a urethane resin, an acrylate resin, and a fluororesin.

A high explosive is a raw material composed of one molecule of fuel and oxidizer, which generates energy at an explosion speed of usually 7,000 m / s or more. Metal particles generate energy when explosive explosion occurs, but oxygen and carbon dioxide The composition ratio of metal particles and high explosives in the composition of the explosive is an important factor determining the performance of the explosive.

If the amount of the high explosive of the inner explosive is less than 30% by weight and the amount of the metal particles is more than 60% by weight in the first decanter 210, the balance between the fuel and the oxygen is not matched and the performance of the explosive deteriorates. If the amount of the metal particles is less than 20% by weight, the content of the metal particles as the fuel is small and it is difficult to expect an increase in the power due to the secondary reaction of the metal.

In addition, since the second contractor 220 requires a high-speed explosive composition in order to cause an overdrive detonation, the high explosive is preferably 70 wt% or more.

In addition, the binder is a constituent material necessary for molding the powder because it plays a role of bonding the high-explosive particles and the metal particles together. However, when the excess is added, the ratio of the energy material to the total weight is lowered so that the detonation of the explosive does not occur, It is preferable that the first promoting part 210 and the second promoting part 220 are both 30% by weight or less.

Accordingly, the first decanter 210 is preferably formed of a gunpowder composition comprising 30 to 70 wt% of a high explosive, 20 to 60 wt% of metal particles, and 10 to 30 wt% of a binder.

Also, the second promoter 220 is preferably formed of a gunpowder composition containing 70 to 90% by weight of a high explosive and 10 to 30% by weight of a binder.

The first decanter 210 and the second decanter 220 are located at the center of the second decanter 220 and the center of the reed body 200. The first decanter 210 and the second decanter 220, Are positioned in the longitudinal direction of the member (100) and are formed to have the same length so as to maximize the effect of the first contracting unit (210).

The diameter of the first decanter 210 may be 30% to 70% of the diameter of the second decanter 220, that is, the inner diameter of the shell body member 100.

When the diameter of the second contractor 220 of the first contractor 210 is 70% or more of the diameter of the second contractor 220, overdrive detonation does not occur, The power of the first contractor 210 can not be expected to be improved if the diameter of the second contractor 220 is less than 30% of the diameter of the second contractor 220.

Table 2 shows the results of the fragmentation force test of Comparative Example 1, Comparative Example 2 and Example. In Table 2, it can be seen that the number of fragments penetration is increased in the warhead with improved power according to the present invention.

The metal particles in the explosive composition increase the density of the explosive composition, react for a longer time than the explosive, and contribute to the expansion of the explosive product, thereby increasing the impact amount and duration of the explosive explosion.

In addition, general high-explosives such as RDX, HMX, and TNT have explosive speeds faster than metal-containing explosives because the reaction speed of the molecules is fast, and the explosive composition composed mainly of high explosives is applied to the fragment effect warhead.
