For achieving the above object, the present invention's high-precision bullet body periphery that 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 similar long helix of the long spirality rifling of gun barrel inside on the surface of grenade, smooth surface is made in the inside of gun barrel, with the resistance of reducing friction, 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 by long helix or the screw wing on the body, do mutually 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, described body periphery is shaped on a plurality of equally distributed spirality guiding gutters from front end to rear end; Described body periphery is shaped on a plurality of equally distributed spirality guiding gutters to the rear end from the middle part; Described body periphery is shaped on a plurality of equally distributed spirality guiding gutters from front end to middle part; Described 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, described 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 described 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, described 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; Described 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; Described 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 that the copper sheet mode is relative with copper body to reduce cost 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.
