Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1
The embodiment discloses a disturbing bullet device for improving smoke screen dispersion effect, as shown in fig. 1, including disturbing bullet body 1, be equipped with the medical kit in disturbing bullet body 1, in the medical kit from interior to exterior have set gradually expanding explosive layer 2, energy-absorbing boosting layer 3 and interfering agent layer 4, be equipped with the fuse that detonates expanding explosive layer 2 on disturbing bullet body 1, energy-absorbing boosting layer 3 includes weight gain granule, weight gain granule's single grain flying ability is stronger than the smoke screen particle flying ability in the smoke screen that interfering agent layer formed, thereby can drive the farther that the smoke screen particle flies, make the smoke screen particle further diffuse, improve smoke screen dispersion radius.
Principle of improving diffusion effect: after the explosive layer 2 is detonated by the fuze, the energy-absorbing boosting layer 3 wrapped around the explosive layer 2 can maximally convert the kinetic energy brought by the explosion energy and the high-temperature high-pressure gas into the kinetic energy of the weight-increasing particles, and then drive the smoke curtain particles generated by the interfering agent layer 4 to diffuse. Meanwhile, because the energy-absorbing boosting layer 3 only replaces part of the filling space of the original interfering agent layer 4, the whole volumes of the energy-absorbing boosting layer 3 and the interfering agent layer 4 are not increased, and the density of interfering materials in the interfering agent layer 4 is not increased, so that the risk of deforming the interfering bomb body 1 can not be extruded during filling, meanwhile, the compaction degree of the interfering materials in the interfering agent layer 4 is not increased, and then the dispersing distance of the interfering materials can not be reduced. Meanwhile, the explosive loading amount in the explosive expanding layer 2 is not increased, and then the scattered and farther broken pieces of the disturbing bullet body are not generated, so that the smoke screen dispersing effect is improved, and meanwhile, the danger caused by farther flying of fragments of the disturbing bullet body 1 is not caused.
In order to avoid the mixing of the weight-increasing particles into the interfering agent layer 4 due to the dispersion of the weight-increasing particles during charging, in this embodiment, the weight-increasing particles are wrapped around the explosive layer by a fixed wrapping member, as shown in fig. 1. The specific fixing wrap can be adhesive tape, plastic collar, cloth tape or plastic tape, etc. which can wrap the weight increasing particles. If the weight gain particles are incorporated into the interfering material in the interfering agent layer 4, which may result in the weight gain particles being in a discrete state, the explosion energy cannot be fully absorbed, and the explosion energy is absorbed by the light interfering material, thereby affecting the diffusion effect.
Further, in this embodiment, as shown in fig. 1, the particle size and density of the single particle of the weight-increasing particle are both greater than those of the smoke screen particle, so that the weight of the single particle of the weight-increasing particle is greater than that of the smoke screen particle, thereby overcoming the air resistance, and further increasing the flight distance, so as to drive the smoke screen particle to fly farther and the diffusion radius to be wider, and further improving the dispersion effect. Meanwhile, the single particle size of the weight-increasing particles is larger than that of the smoke curtain particles, so that the area of the weight-increasing particles is larger, and more smoke curtain particles can be pushed by the single weight-increasing particles, and a better dispersing effect is brought.
Further, in this embodiment, the weight gain particles may be selected from sand grains, stone grains, metal grains, etc., and the required single grain diameter of the sand grains, stone grains, or metal grains is equivalent to the single grain density.
Experiments prove that the weight-increasing particles play a role in transversely dispersing smoke curtains in the bullet disturbing device, and have obvious effects, and in order to obtain the optimal filling amount, in the embodiment, as shown in fig. 1, the mass of the energy-absorbing boosting layer 3 accounts for 10% of the total loading amount mass in a medicine room. After test verification, the average smoke width is 21.1m when no weight gain particles are added; when the addition amount of the weight gain particles is 10%, the average smoke width is 33.0m, and the average smoke width is increased by 56.4%; when the addition amount of the weight gain particles is 15%, the average smoke width is 27.4m, and the addition amount of the weight gain particles causes obvious reduction of the drug loading amount of the interference material, so that the smoke width is reduced; in summary, a suitable addition of weighting particles of 10% is finally established.
In this embodiment, as shown in fig. 1, the detonator comprises an electric detonator 5, the electric detonator 5 is partially embedded in the explosive layer 2, and a wire 6 of the electric detonator 5 extends out of the interfering bomb body 1 and is connected with the detonating device.
Further, in this embodiment, as shown in fig. 1, the explosive layer 2 includes a black cable gold explosive or a TNT explosive, or the like. Further, the shape of the interfering bomb body 1 is preferably a cylinder, the outer diameter is 63.8mm, the inner diameter is 55.8mm, the wall thickness is 8.0mm, and the height is 127.5mm. The radius of the explosive layer 2 is 9.0mm. Of course, the above values and the selection of the explosive is only a preferred mode, and is not represented by the fact that the explosive is only arranged in this way. The cylinder setting mode for the medical kit is the cylinder space, and the explosive layer 2 that expands that sets up in the medical kit, energy-absorbing boost layer 3 and interfering agent layer 4 are cylindric, and the benefit of this setting mode lies in can making energy-absorbing boost layer 3 and interfering agent layer 4 remove radial diffusion as far as possible, and not axial diffusion, thereby guarantees that the smoke screen has bigger dispersion radius in the horizontal direction, has wider interference range.
In this embodiment, as shown in fig. 1, the interfering agent layer 4 includes graphite fiber, carbon fiber, copper powder, or the like, which is a commonly used interfering material. Of course, besides the above-mentioned disturbing materials, disturbing materials which are not known in the market can also be used.
Further, in the present embodiment, as shown in fig. 1, the interfering body 1 is made of a medium carbon alloy steel material. The medium carbon alloy steel has the characteristics of high strength, high hardness, excellent wear resistance, easy control of production process and the like, and compared with high manganese steel and high chromium cast iron, the material has the advantages of low production cost and the like, thereby saving expensive alloy elements.

s2, performing accurate delivery: the method comprises the steps of putting an interference bomb body 1 into a pre-calculated putting area, mainly putting carriers such as a fighter part of a spreader and the like, such as aircraft putting and cruise missile putting, detonating an explosion-expanding medicine layer 2 through a fuze, detonating the explosion-expanding medicine layer 2, and wrapping an energy-absorbing boosting layer 3 at the periphery of the explosion-expanding medicine layer 2, so that the explosion energy generated by the explosion-expanding medicine layer 2 and the kinetic energy of high-temperature and high-pressure gas generated by the explosion-expanding medicine layer 2 can be converted into the kinetic energy of weight-increasing particles to the greatest extent, and then smoke curtain particles generated by an interference agent layer 4 are driven to diffuse outwards to form an interference smoke curtain above a protected object;
s3, completing target protection: the interference smoke screen can reduce the signal intensity of the incident electromagnetic wave, change the electromagnetic wave reflection characteristic of the protection target, and reduce the electromagnetic wave reflection or radiation difference between the protection target and the background, thereby achieving the purposes of shielding and protecting the object.
Further, in this embodiment, as shown in fig. 1, the detonation time point is selected as far as possible when the interfering bomb body 1 is oriented vertically, so that the smoke particles generated by the interfering agent layer 4 can be ensured to spread horizontally, rather than in the height direction, so as to have the largest smoke coverage.
