Description
Technical field
The present invention relates to firearms spiral and store power bullet, be applicable to all grenades, as the bullet of various rifle, the shell etc. of various big gun, belong to firearms technology and science and techniques of defence field.
Background technology
The grenade used now has two large weakness: launching once the bullet being grenade is that blast and the complete explosive expansions of unburned its gunpowder complete not have left shell case to during maximum volume completely at ammunition, such bullet, when leaving shell case, does not obtain maximum kinetic energy; Two is spiral rifling effects that bullet is subject in firearm chamber in firearm chamber, bullet is produced and rotates thus ensure that the flight curve of bullet reaches optimum state, but this spiral rifling makes bullet produce the flying speed inherently reducing bullet when rotating, and namely this spiral rifling can cause certain kinetic energy rejection to bullet; The present invention overcomes this two weakness exactly, makes bullet can obtain maximum ammunition blast kinetic energy before being separated with shell case, bullet can also be made simultaneously to produce spiral rotating, and do not need to utilize firearms spiral rifling to produce spiraling when bullet is separated with shell case.
Summary of the invention
The object of this invention is to provide and a kind ofly can make bullet before being separated with shell case, obtain maximum ammunition blast kinetic energy and the firearms spiral that bullet can be made when bullet is separated with shell case to produce spiral rotating stores power bullet.
Firearms spiral stores power bullet, comprises a shell case and a bullet be enclosed within the shell case foreneck of shell case; It is characterized in that:
1, bullet bullet tail of main gunpowder in shell case is the bullet afterbody concave spherical surface of concave spherical, bullet afterbody concave spherical surface is evenly equipped with three or four threaded hole, threaded hole rotates along warhead-containing body and stretches to bullet cephalad direction, threaded hole is long is 1/1 to three/5th of bullet, threaded hole innermost end conglobate plane be threaded hole bosom disk, the axis parallel of threaded hole bosom disk and bullet, and the extended surface of threaded hole bosom disk is overlapping with the axis of bullet, its objective is that the active force of explosive expansions gas to threaded hole bosom disk making to enter threaded hole can make bullet obtain maximum rotation torque power, threaded hole reduces from the threaded hole entrance of bullet afterbody concave spherical surface gradually to threaded hole bosom its bore dia of disk end, threaded hole entrance and threaded hole are provided with one block of circular threaded hole entrance foamed plastics near the region of bullet afterbody concave spherical surface, the threaded hole entrance foamed plastics of this block circle is met high temperature and can at once be melted, the thickness of threaded hole entrance foamed plastics is no more than 1/2nd of threaded hole length, the effect one of foamed plastics to stop that main gunpowder closely knit in shell case enters threaded hole, two is that the heat fusing of foamed plastics needs the regular hour, the thicker fusing time of foamed plastics is longer, and the time needed for the complete explosive expansions of main gunpowder closely knit in this heat fusing time and shell case is closely related, the excircle of bullet has bullet external screw thread, and the externally threaded pitch of bullet is comparatively large, and namely bullet external screw thread only has one to three screw thread enclosed outside bullet, shell case comprises projectile tail, ignites gunpowder, main gunpowder, ignite reducing, shell case foreneck before barrier between gunpowder and main gunpowder, body, shell case, shell case foreneck internal thread is had in shell case foreneck, shell case foreneck internal thread and bullet external screw thread match, and the bullet external screw thread of bullet rotates and bullet within 0.5 ~ 3 week, can be made from shell case foreneck, to rotate shell case foreneck internal thread and bullet is separated with shell case in shell case foreneck internal thread, bullet external screw thread, shell case foreneck internal thread are consistent with the threaded hole hand of spiral of bullet afterbody concave spherical surface, explosive expansions gas to be entered in threaded hole and the rotation torque power of impacting threaded hole bosom disk and bullet being obtained just makes bullet rotate shell case foreneck internal thread and bullet is separated with shell case along threaded hole, but cross section Ф, the 30o at an angle≤Ф≤60o of the center convolution line of threaded hole bullet axis vertical with bullet.
2, barrier in shell case between the ignition gunpowder of projectile tail and main gunpowder has multiple uniform aperture and barrier hole, the effect in barrier hole is when igniting gunpowder and being ignited district's pressure ignition by projectile tail portion pressure, the flame igniting gunpowder explosion can through the main gunpowder in barrier hole ignition shell case, after main gunpowder explosion, the impulsive force of blast mainly acts on bullet afterbody concave spherical surface, and the foamed plastics of the explosion gas thermalization threaded hole entrance expanded at a high speed, then threaded hole is rushed at a high speed, and promote the bullet generation High Rotation Speed consistent with bullet external screw thread direction, bullet is High Rotation Speed in shell case foreneck internal thread, bullet is made to rotate shell case foreneck internal thread, because it is large that bullet spins out from shell case foreneck internal thread the time t that the time T needed for shell case foreneck internal thread directly skids off needed for shell case foreneck than bullet, i.e. T > t, add heat fusing time and the attack time of explosive expansions hot gas in threaded hole of threaded hole entrance foamed plastics, just make before bullet spins out shell case foreneck internal thread from shell case foreneck internal thread, the main gunpowder of shell case has exploded completely, namely bullet spin out shell case foreneck internal thread from shell case foreneck internal thread before the blast of the main gunpowder maximum kinetic energy that made bullet receive main gunpowder explosion to produce, thus make bullet while high-speed rotary produces shell case foreneck internal thread, bullet obtains maximum initial velocity, and after this bullet obtains this maximum initial velocity, without the decelerating effect of rifling, directly fly out firearm chamber, therefore, bullet can have maximum initial velocity in the moment of the firearm chamber that flies out.
The present invention compared with prior art has the following advantages: 1, the bullet of existing grenade is launched is that blast and the complete explosive expansions of unburned its gunpowder complete just not have left shell case to during maximum volume completely at ammunition, such bullet, when leaving shell case, does not obtain maximum kinetic energy; And bullet of the present invention is after ammunition complete explosive expansions to maximum volume, just make bullet rotate shell case, therefore bullet has obtained maximum kinetic energy before being separated with shell case.
2, rotate to make bullet produce thus ensure that the flight curve of bullet reaches optimum state, the bullet of existing grenade is subject to the spiral rifling effect in firearm chamber in firearm chamber, but this spiral rifling makes bullet produce the flying speed inherently reducing bullet when rotating, and namely this spiral rifling can cause certain kinetic energy rejection to bullet; And bullet of the present invention to rotate be before bullet is separated with shell case, just achieve rotation, doing so avoids bullet and before the firearm chamber that flies out at a high speed, reduce bullet by the decelerating effect of spiral rifling to fly out the initial velocity of firearm chamber.
