Description

The anti-skidding bullet of small-bore sawtooth head height speed

Technical field

The present invention relates to the anti-skidding bullet of small-bore sawtooth head height speed, be applicable to attack the smooth surface with the convex surface arc, such as aircraft, the helmet etc., belong to the science and techniques of defence field, (annotating: if the technology of the present invention needs consideration military security problem, please submit relevant department's audits such as national defence to).

Background technology

Existing used bullet round end nearly all afield, be the zone of arc shiny surface for attacking such as these surfaces such as aircraft and the helmets, if bullet is not to impact on convex surface arc shiny surface with the perpendicular direction front of the tangent line of arc shiny surface, bullet is impossible attack to enter convex surface arc shiny surface, that is to say bullet certainly skid fly inclined to one side! Particularly during attack aircraft, a kind of volume is little, quantity is many, cost is low, the high velocity bullet of far firing range if can have, and is absolutely fatal wound for attack aircraft, but it's a great pity and hear that not such bullet occurs.

Summary of the invention

The purpose of this invention is to provide that a kind of volume is little, quantity is many, cost is low, the anti-skidding bullet of small-bore sawtooth head height speed that is best suited for the convex surface arc shiny surfaces such as attack aircraft and the helmet of far firing range.

The anti-skidding bullet of small-bore sawtooth head height speed, comprise one with the sub warhead of uniform a plurality of limits sawtooth around centre tooth and the centre tooth and cover on sub warhead sawtooth cover on the sub warhead, and a cartridge case that has the larger main powder volume of eldest son's shell case foreneck of the full parcel of sub warhead; It is characterized in that:

1, there is a centre tooth with center wedge angle in sub warhead central authorities, uniform a plurality of shapes and the very sharp limit sawtooth in size tip the same, that crown length is the same around the centre tooth, the cylinder that the lateral surface of all limit sawtooth surrounds and sub warhead cylinder are same cylinder, and the limit sawtooth is slightly shorter than centre tooth; Sub warhead sawtooth capouch section is shaped as circular arc, the district that is connected with the limit sawtooth of sub warhead is shaped as zigzag, and just with the sealing that matches of limit sawtooth, sub warhead sawtooth cover is that friable material is made, make the sub warhead sawtooth cover on high velocity impact to broken immediately when being hit convex surface arc shiny surface, thereby so that this bullet at high-speed impact when the convex surface arc shiny surface, the limit sawtooth can be slided to scrape to tear and be hit convex surface arc shiny surface.

2, the cartridge case foreneck that sub warhead is grown wraps up fully, and the afterbody of sub warhead is that an end of main gunpowder in the contact shoe shell case is the cambered surface with arc-shaped recess, like this can be in cartridge case during main gunpowder explosion, the impulsive force Main Function of blast is on the cambered surface of arc-shaped recess, and the parcel of the cartridge case foreneck through growing makes its detonation power act on the sub warhead body fully, and the impulse force that do not blow up gunpowder enters into bore internal cause diffusion too soon and greatly reduced impulsive force to bullet, thereby this structure can improve the kinetic energy that gunpowder explosion passes to sub warhead significantly, thereby can improve significantly the flight initial velocity of bullet.

3, cartridge case is than the large more lengthening sub warhead that can fill more main gunpowder of sub warhead, it is the diameter of cartridge case than the diameter of sub warhead large 1 ~ 2 times, the length of cartridge case is 5 ~ 10 times of sub warhead length, the initial velocity in the time of can improving widely like this bullet emission.

The present invention compared with prior art has the following advantages:

1, do not have to find to have similar can be than the patent documentation report that is easier to smash the anti-skidding bullet such as convex surface arc shiny surface.

2, make the limit zigzag to sub warhead, can than be easier to sliding scrape to tear hit convex surface arc shiny surface and be not easy to skid and fly partially.

3, the afterbody of sub warhead is that an end of main gunpowder in the contact shoe shell case is the cambered surface with arc-shaped recess, like this can be in cartridge case during main gunpowder explosion, the impulsive force Main Function of blast is on the cambered surface of arc-shaped recess, and the parcel of the cartridge case foreneck through growing makes its detonation power act on the sub warhead body fully, and the impulse force that do not blow up gunpowder enters into bore internal cause diffusion too soon and greatly reduced impulsive force to bullet, thereby this structure can improve the kinetic energy that gunpowder explosion passes to sub warhead significantly, thereby can improve significantly the flight initial velocity of bullet.

The specific embodiment

In the embodiment shown in Fig. 1-4: the anti-skidding bullet of small-bore sawtooth head height speed, comprise one with the sub warhead 11 of uniform a plurality of limits sawtooth 12 around centre tooth 13 and the centre tooth 13 and cover on sub warhead sawtooth cover 14 on the sub warhead 11, and a cartridge case 6 that has larger main gunpowder 7 amounts of eldest son's shell case forenecks 10 of sub warhead 11 full parcels; It is characterized in that: there is a centre tooth 13 with center wedge angle in sub warhead 11 central authorities, uniform a plurality of shapes and the very sharp limit sawtooth 12 in size tip the same, that crown length is the same around the centre tooth 13, the cylinder that the lateral surface of all limit sawtooth 12 surrounds and sub warhead 11 cylinders are same cylinder, and limit sawtooth 12 is slightly shorter than centre tooth 13; Sub warhead sawtooth cover 14 nose shapes are circular arc, the district that is connected with the limit sawtooth 12 of sub warhead 11 is shaped as zigzag, and just with limit sawtooth 12 sealing that matches, sub warhead sawtooth cover 14 is made for friable material, make sub warhead sawtooth cover 14 broken immediately when high velocity impact is hit convex surface arc shiny surface to quilt, thereby so that this bullet at high-speed impact when the convex surface arc shiny surface, limit sawtooth 12 can sliding be scraped to tear and be hit convex surface arc shiny surface.

The cartridge case foreneck 10 that sub warhead 11 is grown wraps up fully, and the afterbody of sub warhead 11 is that an end of contact shoe shell case 6 interior main gunpowder 7 is the cambered surface with arc-shaped recess 9, like this can be at cartridge case 6 interior main gunpowder 7 explosion times, the impulsive force Main Function of blast is on the cambered surface of arc-shaped recess 9, and 10 parcels of the cartridge case foreneck through growing make its detonation power act on sub warhead 11 bodies fully, and the impulse force that do not blow up gunpowder enters into bore internal cause diffusion too soon and greatly reduced impulsive force to bullet, thereby this structure can improve the kinetic energy that gunpowder explosion passes to sub warhead 11 significantly, thereby can improve significantly the flight initial velocity of bullet.

Cartridge case 6 is than the sub warhead 11 large more lengthening sub warheads 11 that can fill more main gunpowder 7, it is the diameter of cartridge case 6 than the diameter of sub warhead 11 large 1 ~ 2 times, the length of cartridge case 6 is 5 ~ 10 times of sub warhead 11 length, the initial velocity in the time of can improving widely like this bullet emission.
