Description

Tactical thermo-pressure grenade

The present invention relates to a grenade, and more particularly, to a thermal pressure grenade capable of breaking or incapacitating a target by using a long-lasting blast overpressure and a thermal effect.

In general, a grenade refers to a small bomb that is thrown by a hand, and the basic configuration is a body and a peony filled therein, and an upper portion protrudes out of the body and connected to a safety device, and a lower portion of the peony inside the body. A primer that is connected to the, usually made of the safety device for controlling the operation of the primer.

In addition, there are various kinds of grenades according to the purpose of use and the characteristics of the composition. Generally, grenades are often referred to as fragmentation grenades that generate debris for the purpose of killing people and destroying equipment and facilities. There is a lot of research and development on the performance and configuration of the fragmentation grenade.

On the other hand, the carcass is ruptured by the explosion to produce debris, mainly made of a metal material of 2.7 ~ 3.3mm thickness, the charge filled in the carcass is a gunpowder having a characteristic that reacts with oxygen at a high speed One of them is mainly trinitrotoluene (TNT) or composition B (composition B, a chemical mixture of hexogen and TNT), which causes a violent explosion reaction to generate sufficient explosion energy to rupture the body of metal material.

Thus, high explosives comprising TNT and Composition B are currently used for most of the above-mentioned fragmentation grenades. In addition, the high explosives, when detonated, cause an explosive chemical reaction for a very short time of several microseconds and an explosion energy that emits intense energy. Here, as the heat and pressure inside the body rapidly rise due to the rapid explosion reaction, the body bursts into numerous pieces and scatters in all directions, and at this time, the fragments of the body are scattered physically to a person, equipment, or machine. Inflict the effect of killing or destroying.

However, in most of the fragmentation grenade, the explosive energy generated by the high explosive is almost consumed by the initial explosive energy to rupture the coal body, so that the damage effect is caused only by the physical blow of the fragments scattered substantially. This is difficult to effectively inflict fatal damage by physical damage only due to the scattering of debris in destroying or incapacitating protection facilities and equipment incorporating modern cutting-edge science and technology.

In addition, at the terminal speed at which the fragments may have a damage effect, since the scattering direction of the fragments is a straight line, various blind spots may be formed around the explosion point depending on the terrain, thereby concealing and concealing. That is, there is a problem that it is difficult to suppress the targets such as behind the cover, inside the building, inside the bunker, and the like. In riot suppression, military operations in the urbanized terrain (MOUT), which are of increasing importance in modern times, the fragmentation grenade is difficult to expect effective damage effects.

On the other hand, the scattering speed of the fragments generated by the bursting of the coal body of the fragmentation grenade is affected by the amount or type of peony filled in the coal body. This means that as the amount of peony increases, the explosive energy that is formed increases, thus increasing the terminal velocity at which the fragments are scattered, while the size of the body to be filled with the increased charge increases and becomes heavier. However, there is a disadvantage in that throwing distance may be reduced or mass carrying becomes difficult. In addition, if the amount of the peony is too small, the explosive energy is weakened and the terminal velocity at which the fragments are scattered becomes low, making it difficult to apply a physical blow.

Hereinafter, a thermal pressure grenade according to a preferred embodiment of the present invention with reference to the accompanying drawings will be described in detail.

1 and 2 and 4 are a perspective view and a cross-sectional view showing a thermal pressure grenade according to an embodiment of the present invention.

As shown in FIGS. 1 and 2 and 4, the thermal pressure grenade 100 of the present invention includes a coal body 40, an ignition device 50, a dispersion ignition weakening unit 60, and a thermal pressure storm charge 13. It is made to include.

In detail, the body 40 includes an upper surface portion 7 and a body portion 10. Here, the upper surface portion 7 is formed with a coupling hole (6) in the center, the size formed to correspond to the open area of the upper portion of the body portion 10 is pinched or coupled to the upper portion of the body portion (10) It is preferable to combine with a completely sealing joint means such as rivet joints.

The inner wall surface of the carbon body 40 is made of a metal material having a thickness of 1 to 1.25 mm, and the body portion 10 is combined with the upper surface portion 7 to form a closed filling space therein. It is preferable that it is provided in the cylindrical (spherical) shape. In addition, after filling the heat pressure storm charge 13 through the filling hole 12 provided in the center of the lower surface of the body portion 10 is coupled to the filling hole 12 so that the inside of the body 40 is sealed. It is preferable that the filling hole cover 13 is included.

In addition, the ignition device 50 is preferably made of a primer 5 having a safety control device at the top, and a fuse gun (8) in the lower portion of the primer (5). Here, due to the packing device provided in the lower portion of the primer (5) is closely coupled to the coupling hole (6), by being disposed on the upper body 40, the body 40 is blocked inside and outside. It becomes sealed state. In addition, the primer 5 may be coupled to the coupling hole 6 in various ways. For example, a female thread is formed on an outer surface of the coupling hole 6 and a screw is formed on an external thread formed on the outer surface of the primer. It is preferable that the coupling means be selected from the means provided with a separate device or the means provided with a separate device so as to prevent the entry and exit between the inside and the outside material, such as to correspond correspondingly.

On the other hand, the primer (5) is an initial ignition means for generating a spark ignition by triggering the ball (4) provided therein by a user's operation, automatic, triggered, electronic and It may be provided by selecting from several types of manual, and during the storage and transport, it is preferable that safety control means for controlling the operation of the primer 5 in consideration of safety is added or inherent.

In addition, the safety operation means is composed of a strike lever (2) and the safety pin (1), the safety pin (1) fixes the strike lever (2) restraining the partition (3). In addition, the safety pin 1 is released and the fixing of the strike lever 2 is released so that the ribs 3 operate the primer 5, and the strike lever 2 is immediately before throwing the body ( By being gripped together with 40), the rib 3 is held in a restrained state until immediately after throwing, thereby controlling the primer 5 not to operate until immediately before throwing.

In addition, the strike lever 2 may be made in various forms ergonomically designed in consideration of the user's easy gripping according to the shape of the body 40, the method of fixing the strike lever 2 is separated It is preferred that it is provided with a fixing means that is easy and does not leave automatically during storage and portable.

In addition, an ignition flame generated by the operation of the primer 5 ignited in accordance with the dismantling of the safety operation means ignites the fuss powder 8, which is from above, zirconium powder, iron oxide and 1.56-1.66 wt% ignitant composed of a mixture of diatomaceous earth, barium chromate, potassium peroxide, 96.40-96.60 wt% retardant composed of a mixture of Zr-Ni (3/7) and Zr-Ni (7/3) It is preferable to laminate-fill in the order of 1.4-1.49 wt% lead azide combustor, and 0.39-0.41 wt% PETN initiator.

Here, the ignition flame transmitted by the operation of the primer 5 burns the ignition agent and sequentially ignites the retardant, the combustion agent and the initiator. In addition, the total combustion time of the fuse gun from the initial ignition to the initiator can be seen as the total combustion time of the retardant, which is Zr-Ni (3/7) and Zr-Ni (7) added to the retarder. / 3) by weight percent.

On the other hand, the Zr-Ni (3/7) and the Zr-Ni (7/3) is 18.5 ~ 21.5 wt% Zr-Ni (3/7), based on the total weight percent including the iron oxide and diatomaceous earth, 4.5 to 7.5 wt% of Zr-Ni (7/3) is included, and when the addition of less than 18.5 wt% of Zr-Ni (3/7) is added, the delay time is less than 4 seconds. . Here, the delay time refers to the time taken until the thermal pressure storm charge 13 is detonated on the basis of the point at which the safety operation means of the thermal pressure grenade 100 is removed and the ignition is started.

In addition, when the delay time is less than 4 seconds, considering the wide effective damage range of the thermal pressure grenades 100, damage to allies is expected, and time margin to throw a sufficient distance toward the target without damage to allies. Is insufficient and the safety is reduced. In addition, a serious strategic loss is expected if an attack is initiated at the thrower's hand or explodes on the way to the target.

In addition, when the Zr-Ni (3/7) is added in excess of 21.5% by weight, the delay time may be longer than 15 seconds, thereby, in an urgent battle situation in which the timely attack is in place, Not only is the efficiency of the thermal pressure grenade 100 rapidly deteriorated, but also a strategic problem by giving the target a space to retreat and remove from the falling point of the thermal pressure grenade 100.

Therefore, after confirming the position of the target, the throwing operation is performed at the same time as the safety control means are removed, and the thermal pressure grenade 100 having started ignition generally has a delay time of about 4 to 5 seconds before reaching the target. need. This is a value calculated for the optimal time needed, including the safety of the thrower and a series of actions to hit the target.

On the other hand, the dispersion ignition agent (9) disposed adjacent to the fuse gun (8) in which the ignition is generated is received in the ignition flame and detonated in series, which disperses and ignites the thermal pressure storm charge (13). Here, the dispersion ignition peony (9) is composed of a mixture of metal powder having a particle size of 3.8-4.2 ㎛ of 15 to 24% by weight and high explosives of 76 to 85% by weight, the filling density of 1.7 ~ 1.9g / ㎠ By compression molding to have a plurality of pellets are laminated in a multi-layer, it is preferably filled so as to occupy 5 to 15% by weight based on the total weight of the heat pressure blow blow medicine (13).

Here, the metal powder affects the strength of the explosion pressure formed by the powder particles which are burned and dispersed during the explosion of the dispersion ignition agent 9 according to the weight% added, which will be described with reference to the attached Table 1. Is as follows.

Weight% 5-9 10-14 15-24 25-29 30-34
Riot strength Bad
(In combustion
Due to extinction) Bad
(Partially
Particle disappearance)
Good Bad
(Combustion status
Inadequate) Bad
(Partial combustion
And insufficient dispersion)

Table 1 is a table showing the state of the explosion at the time of explosion of the dispersion ignition charge (9) according to the added weight% of the metal powder.

As shown in Table 1, when 5 to 9% by weight of the metal powder is added, more particles are extinguished by combustion, so that a sufficient width pressure cannot be formed, and 10 to 14% by weight of the metal powder is added. It can be seen that even in the case of partially extinguished particles, it is difficult to expect to form a sufficient width pressure.

In addition, when 25 to 29% by weight of the metal powder is added, combustion does not occur completely, so that a sufficient width pressure cannot be formed, and when 30 to 34% by weight of the metal powder is added, a phenomenon in which combustion does not occur partially occurs. It occurs repeatedly and it is difficult to expect the efficient function of the dispersion ignition peony (9).

In addition, when 15 to 24% by weight of the metal powder is added, complete combustion occurs to generate a sufficient width pressure, whereby an efficient dispersing function of the dispersion ignition tablet 9 can be expected.

On the other hand, the metal powder may be made of any one selected from the group consisting of aluminum powder, magnesium powder, boron powder, zirconium powder, aluminum / magnesium alloy powder, titanium powder or mixtures thereof, the metal powder used in the present invention is When the dispersion ignition charge (9) explodes, it provides an effect of increasing the explosive power and forming a large flame. In addition, the particle size of the metal powder affects the explosion intensity and the flame intensity of the dispersion ignition agent (9), which will be described below with reference to the attached Table 2.

Table 2 is a table showing the relationship between the explosion intensity and the flame intensity of the dispersion ignition charge (9) according to the particle size of the metal powder.

As shown in Table 2, in the case where the metal powder has a particle size of 50 μm or more, both the explosion strength and the flame strength are insufficient, so that the function of sufficiently dispersing the thermal pressure storm charge 13 in the air at the explosion point is expected. It is difficult to see.

In addition, in the case of having a particle size of 1.0 to 5.0 μm, the explosion strength is good, but only a simple combustion occurs, so that the flame strength is not sufficiently generated. In contrast, at the particle size of 10 to 50 μm, the flame strength is sufficient while the explosion strength is sufficient. You can see that the lack.

However, in the particle size of 5.0 ~ 10 ㎛ it can be confirmed that the result of generating sufficient explosion intensity and flame intensity, which is formed so that the finely formed particles are extinguished before giving a sufficient flame and explosive force in the explosion, on the contrary, if more than the appropriate size This is because combustion of particles does not occur sufficiently. In addition, the particle size of the metal powder is preferably provided to be adjusted within the range of 5.0 ~ 10 ㎛ as a means for causing a strong explosion and high heat in the series of explosions and dispersions that proceed for several hundred milliseconds (msec) or more. .

On the other hand, the high explosives are added in 76 to 85% by weight relative to the total weight% containing the metal powder. Here, the flame strength required for the combustion of the metal powder is changed according to the added weight% of the high explosives, which will be described below with reference to the attached Table 3.

High explosives weight% 56-65 66-75 76-85 86-95
Flame strength
Bad
(Combustion status
Poor) Good
(Partially
Non-combustible particles)

excess

Table 3 is a table showing the change in flame strength according to the added weight% of the high explosives.

As shown in Table 3, when the 56 ~ 65% by weight of the high explosives is added it can be confirmed that the flame strength is small and does not generate sufficient combustion. In addition, when the high explosives of 66 to 75% by weight is added, the flame strength is good, but the metal powder is not partially burned, so it is difficult to generate sufficient flame strength.

In addition, when the high explosives of 86 to 95% by weight are added, the flame intensity is excessively generated more than necessary, so that the effect of the explosion is greater than the dispersion function of the dispersion ignition tablet (9). Can be. Therefore, the high explosives are preferably added within the range of 76 to 85% by weight so as to generate the appropriate flame strength required for burning the metal powder.

On the other hand, the high explosives use hexogen or composition A5, in particular composition A5 is added to the hexogen wax, stearic acid-based enhancer is easy to modify the form or to mix with other materials, accordingly, It is advantageous for processing into pellets by mixing with metal powder. Here, the pellet form refers to those formed in various forms such as donut, disc and cylinder by minimizing the volume by compacting and compacting the powdery materials to form agglomerates and compressing them.

Therefore, it is preferable that the dispersion ignition tablet 9 is compression molded in pellet form in order to eliminate the risk of normal or transport and storage and to ensure a safe production process. In addition, it is provided in the form of pellets, as well as ensuring the safety, provided by a plurality of pellets are laminated, thereby providing an effect of increasing the respective explosive power during explosion.

In addition, the dispersion ignition charge (9) is compression molded in the form of pellets made of a density of 1.7 ~ 1.9g / cm 3, thereby improving the filling density. Here, the filling density refers to the filling weight per unit volume in which the essential components of the optimum weight are filled in a limited space so that they can fully function. By improving the filling density, the performance is improved, and the size and weight are easily affected. The giving factor can have the effect of keeping it appropriate. That is, while reducing the volume of the dispersion ignition weakness 9 in order to provide an improved explosive force and the weight thereof is filled in an appropriate ratio, it is easy to transport, store and carry as the carbon 40 becomes larger or heavier. It prevents deterioration and provides the effect of enabling maneuverability and massive mobility in combat situations.

On the other hand, the thermal pressure grenades 100 vaporize the fuel to generate a decompression and high heat due to a chain explosion in a dispersed state, the thermal pressure storm charge 13 is detonated limit (depending on the phase) ( The characteristics affecting detonation limit, degree of dispersion, initiation energy, and handling safety, etc., where the detonation egg is dissociated with the speed of sound during the exothermic chemical reaction. Together, it creates pressure waves, which are more rapid and intense reactions than the exothermic chemical reactions that simply react with oxygen, such as combustion.

In addition, the fuel generally used includes a gas fuel, a liquid fuel, and a solid fuel according to the phase. Here, the gaseous fuel is rapidly dispersed during the explosion due to the strong volatility, due to this, there is a problem that the detonation is difficult and is affected by the surrounding environment due to the nature of the gas. In addition, there is a disadvantage in that special equipment should be provided due to the high risk of handling due to strong volatility, and because the detonation limit is narrow, it is difficult to be used as a charge of the thermal pressure grenade 100.

In addition, in the case of the liquid fuel, the detonation limit is wide, but there are some flammable fuels even at room temperature without air, and there is a difficulty in handling such as the gaseous fuel when it is burned before dispersing during explosion. And, in order to compensate for the disadvantages of the liquid fuel, it is possible to ensure the safety of handling by adding a gelling agent (gellant), but the detonation limit is narrowed, the dispersion is not made smoothly, the energy required for the detonation is increased and efficient heat Pressure storm effect It's hard to expect.

In addition, the solid fuel can precisely control the size of the particles in the dispersion process, accordingly, can be dispersed with a uniform density distribution compared to the liquid fuel can generate a high pressure during explosion. However, when the size of the particles is formed below an appropriate standard, spontaneous ignition or automatic ignition occurs, and handling is dangerous. On the contrary, when the particles are formed at a size above the standard, dispersion is difficult and energy required for detonation is increased.

On the other hand, the slurry fuel formed by mixing the solid fuel having a high pressure and the uniform density distribution during dispersion and the liquid fuel having a wide explosive limit and a relatively easy detonation is formed in the form of a slurry, which has advantages of the solid fuel and the liquid fuel. Both result in an effect of the applied thermal pressure storm effect. Here, the slurry is a mixture of a solid powder having a uniform particle size and a certain amount of liquid, and refers to a state like a wet sand lump.

In addition, it is easy to handle, to ensure safety in storage and production, to generate a strong explosion and high heat effect by the solid fuel during the explosion, the explosion of the solid fuel to compensate for the relatively high explosion of the solid fuel in a chain explosion By contributing to the advantage, it can be operated considerably more efficiently than gas, liquid, gel and solid fuels.

Therefore, the main fuel of the thermal pressure grenade 100 is provided in a slurry type, the liquid fuel mixed with the solid fuel to form a slurry is nitromethane (Nitromethane), isopropyl nitrate (isopropyl nitrate), molecular weight of 1,000 or less It is preferably selected from the group consisting of saturated hydrocarbons, kerosine-based hydrocarbon compounds and normal heptane and mixed with the metal powder, the high explosives and the oxidizing agent.

Here, the liquid fuel is added in 4.5 to 15% by weight relative to the total weight of the thermal pressure storm charge (13), wherein the slurry formation state according to the weight% of the liquid fuel and the explosion pressure due to the dispersion and combustion of particles The change of overheat is described with reference to the attached Table 4 as follows.

Table 4 is a table showing the state of forming the heat pressure storm charge 13, the dispersion and combustion state of the solid fuel particles, the resulting pressure and high heat generation state according to the weight% of the liquid fuel.

As shown in Table 4, when the liquid fuel is added at less than 4.5% by weight, a slurry-type hot-pressure storm peony with a weak viscosity is formed, and it is difficult to handle because it is brittle or difficult to maintain its shape, and detonates the solid fuel. It may be confirmed that the dispersion state of the particles is not good because the energy necessary to make it is not provided sufficiently. As a result, the strength of the explosion and high heat is weakened, so it is difficult to expect an effective heat pressure storm effect.

In addition, when the liquid fuel is added at 15.6 to 30% by weight, the viscosity becomes too strong and close to the liquid. For this reason, the partial combustion of the liquid fuel at the time of detonation proceeds rapidly and disappears, so that combustion of the solid fuel particles is incomplete. In addition, although it is dispersed in a large area which is a characteristic of a general liquid fuel, it is possible to confirm a phenomenon of generating low pressure and heat.

On the other hand, when the liquid fuel is added in the amount of 4.5 ~ 15.5% by weight, it is properly mixed with the solid fuel to form a good slurry heat pressure storm charge, and the particles of the solid fuel have a uniform density distribution and are dispersed and burned in series. It can be confirmed that is generated satisfactorily, the effect of generating the pressure and high heat. Therefore, it is important that the liquid fuel is mixed with the solid fuel to form a heat pressure storm peony in a uniform state, and thus it can be seen that the main function of the heat pressure grenade is efficiently formed.

In addition, the thermal pressure storm charge 13 is 20 to 60% by weight of the thermal pressure metal powder, 10 to 60% by weight of the high explosives, 4.5 to 20.5% by weight of the oxidizing agent, 4.5 to 15.5% by weight of the liquid fuel and 0 ~ It has a density of 1.5-1.8 g / cm 3 with 10% by weight of additives.

Here, the hot-pressure metal powder is the main raw material of the heat-pressure storm peony (13) that generates the explosion and high heat, aluminum powder, magnesium powder, aluminum and magnesium alloy powder, boron powder, zirconium powder, titanium powder or mixtures thereof It consists of any one selected from the group consisting of. In addition, the thermal pressure metal powder is different depending on the particle size of the dispersion and explosion time, the explosion pressure and the intensity of the high heat according to the combustion, which will be described with reference to the accompanying Table 5.

Table 5 is a table showing the relationship between the intensity of the explosion and the high heat according to the dispersion, explosion time, combustion state according to the particle size of the thermal pressure metal powder.

As shown in Table 5, in the particle size of 50 ~ 150 ㎛ it can be seen that the combustion does not occur partially incompletely in a short time. In addition, similar results are shown in the particle size of 500 ~ 600 ㎛, which indicates that when the particles are formed below or more than the appropriate size, only a simple combustion occurs without explosion and combustion within a short time during the explosion. In addition, when the particle size is 500 µm or more, the dispersion is not sufficiently uniform in density, and the energy required for combustion is increased, thereby decreasing efficiency.

In addition, in the particle size of 150 ~ 200 ㎛ to 400 ~ 500 ㎛ generally shows good dispersion and combustion state, but it is difficult to expect the optimum thermal pressure explosion effect because the explosion time is not achieved within a short time. . Therefore, in order to expect sufficient explosion pressure and high heat in the explosion of the thermal pressure storm charge 13, the thermal pressure metal powder is preferably provided with a particle size of 200 ~ 400 ㎛.

On the other hand, the high explosive is one of the strongest of the explosion among the various types used in the high-explosive, and is added for the explosion and complete combustion of the metal powder, forming a strong explosion in the initial explosion, and burned in series Serves as a combustion aid of the metal powder. In addition, when the high explosives are added at less than 10% by weight, the metal powder is not completely burned, and when the explosives are more than 60%, the duration of the explosion and high heat is shortened. It is difficult to expect a sustained reduction in intense pressure and high fever. Therefore, the high explosives are preferably added at 10 to 60% by weight so as to efficiently provide the function.

In addition, the oxidant is added as a sensitizer to improve the ignition sensitivity of the heat pressure storm charge 13, and explodes quickly when the heat pressure storm charge 13 is detonated to satisfy the energy conditions required for the explosion. Generates. However, when added in less than 4.5% by weight, the explosion time may be delayed or misfired. On the contrary, when added in excess of 21% by weight, an instantaneous instantaneous explosion occurs at the same time as the explosion, making it difficult to expect continuous chain explosion. . Accordingly, the oxidizing agent is made of any one selected from the group consisting of nitrates, perchlorates, or mixtures thereof, and the amount of the oxidizing agent is appropriately adjusted in the range of 4.5 to 20.5% by weight to predict the time of explosion. It is preferable to add in the inside.

On the other hand, the dispersion ignition peony (9) optimally plays a role of dispersing the air pressure storm peony (13) in a uniform distribution and the initial detonation of the chain explosion process lasting for several hundred milliseconds (msec). In order to be able to perform, it is preferable to be filled to occupy 5 to 15% by weight based on the total weight of the thermal pressure storm charge (13).

Here, if the dispersion ignition peony (9) is added less than 5% by weight based on the results calculated through its own experimental data, the explosive power is insufficient to sufficiently disperse and detonate the thermal pressure storm peony (13) On the contrary, when added in excess of 15% by weight, only the power of a simple explosion is increased and the thermal pressure explosion effect is lowered, as well as the production cost is unnecessarily increased and the production speed is lowered, thereby lowering productivity.

On the other hand, the thermal pressure storm charge 13 is dispersed in the air while detonated and exploded by the explosion of the dispersion ignition charge (9), the dispersed fuel is not exploded temporarily, but in series with the oxygen in the air Combustion results in a thermal pressure storm effect that generates continuous bursting and high heat for hundreds of milliseconds (msec), where the thermal pressure storm effect creates flames of 1,000 ° C. or more in a radius of 2 to 3 m and the storm overpressure ( blast overpressure) has a performance of greater than 6-7 psi at a radius of 3-4 m and greater than 1.4 psi at 7 m.

In addition, the dispersed fuels of the thermal pressure storm charge 13 are mixed with the air around the target and are instantly dispersed surrounding the terrain, cover and equipment. In addition, the explosion and high heat generated by the cascading explosions cause tympanic rupture, lung damage, blindness, temporary blindness, and fatal damage even in and around irregular terrain or cover and equipment. As riots and high temperatures continue to be formed uninterrupted by terrain, virtually no concealment can be achieved, and the effectiveness of target suppression can be maximized, especially when operating in urban battles, counter-terrorism operations, and riot suppression.

In addition, the thermal pressure storm charge 13 may generate a large amount of smoke followed by a strong explosion and flash at the same time as the explosion, thereby providing an additional effect of smoke grenades and flash grenades, which is outside the effective damage range of the explosion and high heat It can also be used as a means of effective target suppression as a non-lethal weapon.

On the other hand, the thermal pressure storm peony 13 is weak in strength compared to the explosive force of the high explosives for the formation of fragments of conventional fragmentation grenades in the initial explosion. Here, the fragmentation grenade is filled with a high explosive with a strong initial explosion pressure is used to burst the energy generated during the explosion, generally to rupture the body of the metal material consisting of a thickness of 2.7 ~ 3.3 mm, substantially Most of the explosive energy is exhausted. Therefore, the physical blow effect by the scattering of the debris can be said to be the main function of the fragmentation grenade. Here, the thermal pressure grenade 100 is an incidental debris effect caused by the body 40 during the explosion, thereby maximizing the efficiency of the target suppression by providing a physical impact effect and subsequent explosion and high heat effects .

Therefore, in order to minimize the explosive energy of the high explosive explosive debris is formed during the initial explosion, the thermal pressure grenade 100, PITN, hexogen (RDX), octogen (HMX) And nitroguanidine (Nitroguanidine) any one selected from the group consisting of 10 to 30% by weight relative to the total weight of the heat pressure storm charge (13) is added.

Therefore, in general, the leaf pressure storm peony 13 has the characteristics of continuous explosion and high heat, by improving the initial explosion pressure by adding a certain amount of the high explosives, the explosion energy required for the rupture of the body 40 The loss of the thermal pressure storm charge 13 was minimized. On the other hand, the embossed groove on the inner wall surface of the coal body 40 formed relatively thin compared to the coal body of the fragmentation grenade in addition to adding the high explosives to strengthen the power of the initial cracking pressure as a method for efficiently forming the fragments. By forming the in the longitudinal and transverse direction can be expected a secondary damage effect by the debris.

In addition, when throwing the heat-pressure grenades 100, it is preferably made of a size that can be tightly wrapped around the user's hand.
