[0002] It can be seen from the modern local wars and armed conflicts that have occurred in recent years that combat missions are no longer limited to large-scale destructive damage to targets. Small-scale and urbanized combat has become a distinctive feature of modern warfare. Cities are the most likely battlefields in the 21st century.

[0003] Urban warfare faces a special environment with dense populations, many buildings and crowds. Under the requirement of precise strike tactical objectives, ammunition needs to be able to accurately hit the target while effectively controlling the scope and degree of damage to prevent killing non-strike targets.

The flight distance of the shrapnel is within the destructive range of the ammunition. The destructive range is uncontrollable, which is not conducive to precise strikes on targets, is easy to hurt innocent people, and has high collateral damage to the target.

[0040] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0041] Example 1

[0042] A specific embodiment of the present invention, as Figure 1 As shown, a near-field high-efficiency striking device (hereinafter referred to as the striking device) that utilizes detonation to drive heavy metal particles is disclosed, comprising a shell 1, a main fuze 2, an explosive column 3 and kinetic energy powder 4, wherein the explosive column 3 is arranged on the shell 1, one end of the main fuze 2 is connected to the shell 1, and the other end of the main fuze 2 is connected to the explosive column 3, the kinetic energy powder 4 is arranged in the shell 1 and is sleeved on the explosive column 3, and the kinetic energy powder 4 is used to utilize the kinetic energy provided by the explosion of the explosive column 3 to strike the target.

[0043] Preferably, the kinetic energy powder 4 is a small particle of heavy metal, with a length of less than 0.1 mm and a weight of less than 0.1 g, and the small particles of the kinetic energy powder 4 have an irregular surface shape. After the explosion of the detonating charge column 3, the near-field shock wave overpressure is enhanced, and the kinetic energy powder 4 can absorb the explosion energy. Under the same charging conditions, the flying distance of the kinetic energy powder 4 is less than that of the prefabricated fragments of the same mass, and the striking radius of the kinetic energy powder 4 is less than that of the prefabricated fragments. The striking device of this embodiment has a small damage range and low collateral damage to the target.

[0044] Preferably, the outer shell 1 is a non-metallic shell. After the explosive column 3 explodes, the outer shell 1 can break, but no lethal fragments are generated, and the target cannot be hit, and the killing range is controllable.

[0045] Compared with the prior art, the prefabricated fragments use kinetic energy to strike the target. The flight distance of the prefabricated fragments is within the damage range of the ammunition. The kinetic powder 4 can absorb the explosion energy. Under the same charging conditions, the flying distance of the kinetic powder 4 is less than that of the prefabricated fragments of the same mass. The striking radius of the kinetic powder 4 is smaller than that of the prefabricated fragments. The striking device of this embodiment has a small damage range and low collateral damage to the target.

[0046] Example 2

[0047] Another specific embodiment of the present invention, as Figure 2 As shown, on the basis of Example 1, the striking device of this embodiment adds a fire transfer tube 5 and a packaging unit 6, and improves the arrangement of the explosive column 3. The kinetic energy powder 4 is arranged in the packaging unit 6, and the loose kinetic energy powder 4 is packaged, so as to control the damage range of the kinetic energy powder 4.

[0048] In Example 1, the striking device uses kinetic energy powder 4 to strike the target, but the precise striking range of the kinetic energy powder 4 is not controllable, resulting in an uncontrollable killing range of the kinetic energy powder 4 and an uncontrollable incidental damage range.

[0049] Preferably, the fire transfer tube 5 is arranged on the housing 1, one end of the main fuse 2 is connected to the housing 1, the other end of the main fuse 2 is connected to the fire transfer tube 5, and the explosive column 3 is sleeved on the fire transfer tube 5. The fire transfer tube 5 is used to transfer the flame of the main fuse 2 to the explosive column 3.

[0050] Preferably, the packing unit 6 is arranged in the outer shell 1, and the kinetic energy powder 4 is arranged in the packing unit 6. The kinetic energy powder 4 and the packing unit 6 together constitute a prefabricated striking block. The kinetic energy powder 4 stores energy for the packing unit 6, so that the packing unit 6 maintains the flight speed and kinetic energy. The prefabricated striking block within the striking radius can damage the target; outside the striking radius, the packing unit 6 disintegrates, the kinetic energy powder 4 separates, the windward area of ​​the kinetic energy powder 4 expands, the speed of the kinetic energy powder 4 drops rapidly, the kinetic energy decays rapidly, the kinetic energy powder 4 has no lethality, and has no destructive effect outside the killing radius. The striking range of the striking device of this embodiment is controllable, and the collateral damage to the target is low.

[0051] For example, when the charge amount of the explosive column 3 is the same, the mass of a single prefabricated fragment is the same as the mass of a prefabricated striking block, and the number of prefabricated fragments is the same as the number of prefabricated striking blocks. It can be concluded that the prefabricated fragments and the prefabricated striking blocks have the same total killing radius.

[0052] For example, Figure 3 As shown, the excitation point of the striking device is point o, the total striking path is section oa, the controllable striking distance required by the striking device of this embodiment is b, the controllable striking path is section ob, the low collateral damage is section ba, the units of a and b are both m, and a>b; in section oa, the prefabricated striking block can damage the target; at point b, the packaging unit 6 disintegrates, the kinetic energy powder 4 separates, the windward area of ​​the kinetic energy powder 4 expands, the speed of the kinetic energy powder 4 drops rapidly, and the kinetic energy decays rapidly. Compared with the prefabricated fragments that still have lethality in section ba, the kinetic energy powder 4 of this embodiment has no lethality in section ba, the kinetic energy powder 4 has no damaging effect, and the collateral damage to the target is low.

[0053] Preferably, Figure 4 As shown, the packaging unit 6 includes a cover 61 and a decomposition mechanism, the kinetic energy powder 4 is arranged in the cover 61, and the decomposition mechanism is arranged on the cover 61. After reaching the damage radius of the prefabricated striking block, the decomposition mechanism is used to decompose the cover 61 to separate the multiple kinetic energy powders 4, and a single kinetic energy powder 4 has no lethality.

[0054] Preferably, the decomposition mechanism includes a decomposition fuse 62, a pulling rope 63 and a decomposition charge 64, the decomposition fuse 62 and the decomposition charge 64 are both arranged on the cover 61, and the decomposition fuse 62 and the decomposition charge 64 are connected, one end of the pulling rope 63 is connected to the decomposition fuse 62, and the other end of the pulling rope 63 is connected to the fire transfer tube 5. After the detonating charge 3 explodes, kinetic energy is given to the sub-packaging unit 6, and the cover 61 and the kinetic energy powder 4 move rapidly in a direction away from the fire transfer tube 5. Since the pulling rope 63 is connected to the fire transfer tube 5, the decomposition fuse 62 is pulled, the decomposition fuse 62 is ignited, and the decomposition fuse 62 ignites the decomposition charge 64, so that the cover 61 is decomposed.

[0055] Preferably, the decomposition fuze 62 is a delayed fuze, and the ignition time of the decomposition fuze 62 determines the flight time of the prefabricated striking block, thereby determining the striking distance of the prefabricated striking block, ultimately achieving controllable striking range of the striking device of this embodiment. In addition to the strike of the prefabricated striking block, the collateral damage of a single kinetic energy powder 4 to the target is small.

[0056] In a certain possible implementation, the decomposition charge 64 is a single charge block, and the decomposition charge 64 can explode and blow open the cover 61, thereby scattering the kinetic energy powder 4 in the cover 61, thereby disintegrating the prefabricated striking block.

[0057] In a possible embodiment, the decomposition charge 64 is a mesh charge, and the decomposition charge 64 is set on the surface of the cover 61. After the decomposition charge 64 explodes, the cover 61 can be divided into multiple pieces at the same time, and multiple kinetic energy powders 4 can be scattered, thereby disintegrating the prefabricated striking block. The cover 61 is broken into multiple pieces after decomposition, which reduces the collateral damage of the cover 61 to the target.

[0058] Preferably, Figure 2 As shown, in order to connect multiple pulling ropes 63 to the fire transfer tube 5, there are multiple explosive columns 3, and they are arranged at intervals on the fire transfer tube 5. Between two adjacent explosive columns 3 is an exposed section of the fire transfer tube 5, and the pulling rope 63 can be connected to the outer wall of the exposed section, thereby connecting the decomposition fuse 62 to the fire transfer tube 5.

[0059] Compared with the technical solution of Example 1 which only utilizes a plurality of kinetic energy powders 4 to spontaneously aggregate to form a striking block, the striking block damages the target within the near-field radius, and relies on the striking block to disintegrate itself in the far field, thereby reducing the collateral damage to the target, the striking device of this embodiment uses the ignition time of the decomposition fuse 62 to set the striking distance of the prefabricated striking block. After the decomposition charge 64 explodes, the cover 61 can be divided into multiple pieces at the same time, and the plurality of kinetic energy powders 4 can be dispersed, thereby actively disintegrating the prefabricated striking block, and finally realizing that the striking range of the striking device of this embodiment is controllable. In addition to the strike of the prefabricated striking block, the collateral damage of a single kinetic energy powder 4 to the target is small.

[0060] Example 3

[0061] Another specific embodiment of the present invention, as Figure 5 As shown, the packaging unit 6 is improved on the basis of Example 2, the decomposition charge 64 is eliminated, and an isolation layer 7 is added. The striking device of this embodiment can completely decompose the cover 61 and completely eliminate the collateral damage of the fragments of the cover 61 to the target.

[0062] Preferably, the cover 61 is a combustible cover. Specifically, the cover 61 is a preformed pyrotechnic cover, and the decomposition fuse 62 can ignite the cover 61, and the cover 61 can be completely burned to form smoke or dust. After the cover 61 is decomposed, no large pieces of debris are generated, thereby completely eliminating the collateral damage to the target.

[0063] Preferably, in order to prevent the explosion of the explosive column 3 from igniting the cover 61, the striking device of this embodiment further includes an isolation layer 7, which is arranged on the outer shell 1 and completely wraps the explosive column 3, and the pulling rope 63 is connected to the isolation layer 7. The isolation layer 7 is an elastic isolation layer, and the gas generated by the explosion of the explosive column 3 can push the isolation layer 7, and the isolation layer 7 can throw the subpackaging unit 6 away from the isolation layer 7. The isolation layer 7 can isolate the gas generated by the explosion of the explosive column 3 from the cover 61 to prevent the cover 61 from being ignited.

[0064] Compared with Example 3, the decomposition fuse 62 of this embodiment can ignite the cover 61, and the cover 61 can be completely burned to form smoke or dust. After the cover 61 is decomposed, no large fragments are generated, thereby completely eliminating the collateral damage to the target.

[0065] Example 4

[0066] Another specific embodiment of the present invention discloses an incendiary bomb, in which the kinetic powder 4 is replaced on the basis of the third embodiment. The striking device of this embodiment can ignite the sub-packaging unit 6. In addition to kinetically striking the target, it can also ignite the target and perform a combustion strike on the target.

[0067] Preferably, the striking device of this embodiment replaces the kinetic energy powder 4 with a combustion agent. The decomposition fuse 62 can ignite the cover 61 and the combustion agent, and in addition to performing a kinetic strike on the target, it can also ignite the target and perform a combustion strike on the target.

[0068] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
