Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
The bottom of a traditional detonator transfer shell is of a plane structure, when a detonator is used for detonating main explosive of a warhead, the gap distance between the detonator transfer shell and the main explosive of the warhead needs to be strictly controlled, and if the distance is too large, the detonation is incomplete. Based on the above, when the detonator explodes the warhead, a ridge rib structure is processed on the flat bottom of the explosion transfer medicine shell between the detonator explosion transfer medicine and the main explosive of the warhead, specifically, a ridge rib ring and more than two ridge ribs are arranged on the bottom surface of the explosion transfer medicine shell, wherein the ridge rib ring is positioned in the middle of the bottom surface, and each ridge rib is distributed on the outer side of the ridge rib ring along the radial direction of the ridge rib ring; meanwhile, the booster shell and the ridge rib structure at the bottom of the booster shell are integrally processed, so that the shape of the booster does not need to be changed.
As can be seen from the planar shape of the ridge structure shown in fig. 1, the center of the bottom surface of the circular housing is a regular hexagon which is outwardly divergent from 6 corners of the regular hexagon and is similar to a steering wheel shape, the structural design is favorable for generating a beam energy effect when the booster explosive is detonated, the beam energy effect can enable detonation impact beam energy generated by detonation of the booster explosive and main explosive of the warhead to be impacted at high speed by a broken piece generated by rupture of the booster shell, so that complete detonation of the main explosive is promoted, and the damage effect of the warhead is improved. Meanwhile, the circular bottom surface is not separated by the outwards diverging boundaries of the six corners of the regular hexagon, and a gap is formed between one end of each ridge rib, which extends outwards along the radial direction of the regular hexagon ridge rib ring, and the outer boundary of the bottom surface of the booster casing, namely between the diverging boundary line and the outer boundary of the bottom surface of the booster pipe, so that the blasting rate of the booster casing can be increased.
As shown in figure 2, the ridge rib structure on the bottom surface of the booster shell is convex, and has a strengthening effect on the beam energy. The bulge part is made of thicker material, and compared with the surrounding thinner area, the initiation energy of the booster is easier to penetrate the surrounding thinner area, so that the initiation energy of the detonator booster is forcedly divided into six detonation impact energy beams, and the detonation energy beams have an energy gathering effect, can gather the initiation energy of the booster in the ridge rib structure, and together with a fragment generated by the rupture of the booster shell, impact the main charge of the warhead at high speed, and enable the main charge of the warhead to be completely detonated.
In addition, as the explosion energy is smaller towards the outside, the energy of the outer boundary is not vertically deep into the explosive, and compared with the vertical intake of the energy of the explosive at the circle center, the thickness of each ridge rib is smaller and smaller along the direction extending towards the outer boundary of the bottom surface of the booster shell, so that the energy loss can be better reduced.
It should be noted that the ridge ring may be a regular hexagon as shown in fig. 2, or a regular pentagon or a circle as shown in fig. 4 to 5, which may be used to replace the ridge structure as shown in fig. 2, and is intended to divide the bottom surface of the explosive shell into different areas, so that the explosive energy and the explosive shell fragments enter the main charge simultaneously and simultaneously in the same direction through the forcedly divided areas, thereby deepening penetration depth and promoting complete detonation of the main charge. In addition, the beam energy effect of the explosive can also be achieved for other explosive shell bottom structures similar to fig. 4-5. If the detonator adds the explosive-expanding agent between the booster and the main explosive of the warhead, the energy-bundling structure of the explosive-expanding tube shell can also adopt the ridge rib structure.
The working principle of the invention is as follows:
after the booster explosive is detonated, the booster explosive shell also begins to break, and the ridge rib structure of the booster explosive shell enables the explosion expanding energy of the booster explosive to gather towards the region, so that the main explosive of the warhead is impacted by the detonation shock wave and the fragments at high speed like energy beams, and the main explosive is completely detonated. That is, the invention provides an energy-transmission tube shell energy-bundling ridge structure with the effect of detonating fuse detonation warhead main charge, which can bundle energy of detonating fuse detonation powder to lead the detonating direction to generate energy-bundling phenomenon along the ridge structure divided region, thereby gathering more energy of traditional single-beam multi-direction detonating energy, impacting the warhead main charge at high speed together with a rupture disk generated by the rupture of the shell of the detonator, leading the detonation to be complete, improving the damage effect of the warhead main charge, and not needing to strictly control the distance between the detonating fuse tube shell and the warhead main charge.
As can be seen from fig. 3, the junction of the ridge rib structure thickness belongs to the weak link during explosive explosion, and the weak portion of the ridge rib structure is firstly broken during explosive transfer explosion, so that energy gathers to the first broken portion, energy in the same direction is increased, the energy binding effect is achieved, and the main explosive of the warhead is impacted at high speed together with the fragments generated by the broken explosive cartridge shell, so that the main explosive is completely detonated, the damage efficiency of the main explosive is improved, and the gap distance between the detonator transfer cartridge and the main explosive of the warhead is not required to be strictly controlled.
It should be noted that when the explosive is exploded without adding a ridge structure, the main charge plane is exploded, and the explosion is incomplete; however, according to the concept of stress concentration, the stress concentration can cause fatigue cracks on the object at the place where the shape of the object changes rapidly, and can also cause static load fracture of the part made of the brittle material, and the place where the ridge rib ring and the ridge rib are arranged on the bottom surface of the booster shell is the place where the shape of the object changes rapidly, so the place where the ridge rib structure is arranged is easy to fracture and blast. On the other hand, if the division of the explosive ridge rib structure is too much and the energy division is not obvious, energy extrusion is easily caused, so that the energy penetration is reduced, and the main charge detonation efficiency is reduced. For a cylindrical main charge, sufficient initiation is required to ensure that the initiation energy is sufficiently deep from different directions. For a round detonating face, the energy dispersion angle of 60 degrees can ensure that the energy is uniformly divided into deep regions, the energy collision consumption which is not obviously generated in the region when the energy is unidirectionally divided into deep regions is reduced, and meanwhile, the energy is uniformly distributed into deep regions, so that the main charge can be simultaneously detonated in different directions, and the detonating efficiency of the main charge is improved.
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it will be understood by those skilled in the art that various changes and modifications may be made herein without departing from the spirit and scope of the invention as defined in the appended claims.
