Description
Technical field
The present invention relates to a kind of firearms bullet, particularly relate to and a kind ofly can simplify the high-precision bullet of structure of firearms life-saving and the firearms of adapted.
Background technology
At present, scientific and technical high speed development, living standards of the people improve day by day; Think of danger in times of safety, the national defense construction dynamics has coincidentally been strengthened in countries in the world, and high-new sophisticated weapons continue to bring out; Following war will be comprehensively competing fiercely of a national economy strength and science development degree and human resources, but facts have proved, the still people of final decision war win and defeat; The final the most basic factor that solves war is exactly the soldier; And soldier institute employable be prevailing conventional weapon just, also why loosen the research of conventional weapon in the high-new sophisticated weapons of development not countries in the world just for this, the reason place that dare not adopt a casual attitude.And conventional weapon is exactly rifle, big gun at all, and rifle, big gun be at all on the ammunition that rifle, big gun are served ammunition.Conventional weapon bullet, shell mainly rely on the emission medicament that carries in the shell case, in bore, bore, lighted high temperature, the gases at high pressure that explosion time moment produces and promoted work done down, with bullet through rifle, the ejaculation of gun tube mouth.For the bullet that makes ejaculation stably, hit the mark exactly, must let it rotate, therefore in gun barrel, gun tube, installed long helix, guarantee that bullet can rotate, stablizes, fly to exactly target.But so, just caused that gas pressure strengthens in the bore, bore, temperature raises, frictional resistance strengthens, made rifle, inner serious the ablation and wearing and tearing of gun tube, the life-span of rifle, big gun is shortened greatly.After bullet breaks away from gun barrel, gun tube, rely on the rotation and the linear inertia motion potential energy directive target of self storing, bullet is in the process of motion, the rotation of its storage and rectilinear motion potential energy are decayed gradually; But the decay of their potential energy is out-of-proportion, at first be that rotatory inertia potential energy decays to null value, but linear inertia potential energy is also stronger; Continue flight forward so bullet will roll under the influence of air drag and himself gravity, but departed from original movement locus normal gradually, promptly lost target; Blind flight; Make remaining line inertia potential energy become meaningless, slatterned, its effective range is reduced greatly.
In order to strengthen the effective range of firearms, strengthen the initial velocity of bullet head, shells head, so; What people had increased the weight of bullet, shell penetrates the medicine Load, ceaselessly studies the new medicament prescription, the pipe shaft of the firearms of having thickeied, extended; So, though the range of firearms has been increased much, the ratio of its range and effective range does not change; Fundamentally do not change the waste problem of range, greatly increased the weight of firearms, though in recent years along with development of science and technology; The manufacturing that many new materials are constantly applied to firearms comes up, and does not effectively penetrate the root problem of ratio existence of ` journey but all fundamentally change firearms weight with it.
Summary of the invention
The objective of the invention is to overcome the above-mentioned defective of prior art, a kind of high-precision bullet that can simplify the structure of firearms life-saving is provided, the object of the invention also is to provide the firearms of this bullet adapted.
For realizing above-mentioned purpose, the high-precision bullet body periphery that the present invention can simplify the structure of firearms life-saving is shaped on a plurality of equally distributed spirality guiding gutter (rifling formula guiding gutter) or the screw wing that extends from front to back.Promptly be provided with the inner similar long helix of long spirality rifling of gun barrel, smooth surface processed in the inside of gun barrel, with the resistance of reducing friction on the surface of grenade; Reduce gun pressure, increase the initial velocity of body, body flies forward after breaking away from the firearms mouth of pipe; With windage, because the long helix on the body or the effect of screw wing, when air is given rotating moment of body when flowing through these long helixes or screw wing; Bullet is rotated on one side; Flight forward on one side, as long as body has the potential energy of flight forward, it will be through long helix or the screw wing on the body; Do each other with air and produce a rotating moment, make missile rotation flight forward.Rotatable like this body priority application is in bullet, and the big gun howitzer is on high-explosive plastic projectile and the general high explosive anti-tank cartridge.Here, screw wing mainly is applicable to rocket projectile, also can be applicable to all grenades certainly.After firearms save rifling, can simplify structure, can reduce cost again; Particularly because the hardness of firearm chamber is all big than bullet, the bullet periphery all is brass usually, so; After rifling moved on on the bullet, not only hard but also smooth in the gun barrel, bullet was not only soft but also the spirality guiding gutter arranged; Certainly wearing and tearing has just had only bullet, and therefore the air-tightness between gun barrel and the bullet can not reduce yet certainly.So design, it can prolong firearms service life greatly, simplifies structure of firearms; Gun barrel has saved rifling attenuation relatively; Prolong firearms service life, also saved rifling cleaning expense in the gun barrel, particularly can significantly improve effective range and fire accuracy.
As optimization, said body periphery is shaped on a plurality of equally distributed spirality guiding gutters from front end to rear end; Said body periphery is shaped on a plurality of equally distributed spirality guiding gutters to the rear end from the middle part; Said body periphery is shaped on a plurality of equally distributed spirality guiding gutters from front end to middle part; Said body periphery middle part is shaped on a plurality of equally distributed spirality guiding gutters.So design can be selected to be suitable for.
As optimization, said spirality guiding gutter widen or widen intensification from front to back gradually.Design like this can strengthen revolving force, the frictional resistance between reduction and the air relatively.
As optimization, the sidewall that said spirality guiding gutter is positioned at the hand of spiral one side is the gentle slope wall, and the sidewall of opposite side is the vertical wall vertical with the body periphery.So design, vertical wall is used to increase rotary driving force, and the gentle slope wall is used to reduce windage.
As optimization, said body is the cylinder bodily form of front end band point, and paracone part or column part or whole periphery are shaped on a plurality of equally distributed spirality guiding gutters; Said body is the cylinder bodily form of double headed roller point, and paracone part or back nose part or column part or whole periphery are shaped on a plurality of equally distributed spirality guiding gutters; Said body is the spindle bodily form of double headed roller point, and paracone part or the part or all of periphery of metacone are shaped on a plurality of equally distributed spirality guiding gutters.So design, the convenient selection is suitable for.
As optimization, the steel body periphery that is shaped on the spirality guiding gutter coats layer of copper again.So design, copper sheet can reduce the gun barrel wearing and tearing to greatest extent, add the copper sheet mode and copper body can reduce cost relatively greatly.
The firearms that the present invention can simplify the high-precision bullet adapted of structure of firearms life-saving are to be smooth inner surface in the gun barrel.Can simplify structure of firearms, weight reduction reduces cost, saves the rifling maintenance cost, increases the service life etc.
After adopting technique scheme, the high-precision bullet that the present invention can simplify the structure of firearms life-saving has can simplify structure of firearms, weight reduction; Reduce cost; Save the rifling maintenance cost, increase the service life, can significantly improve the advantage of effective range and fire accuracy.
