Abstract

The invention discloses a kind of no-ejection gun projectile in expansion end and sealing bore type, wherein a warhead stretches back out of the steel shell and is conjoined with propellant, then coated with a more backward copper sheet, an expansion end of the copper forms with an interference fit with the gun bore and highly suppress out of emission energy, and landfills the error influence of the common large rigid projectile. The invention is characterized by increase of range and easy increase of firing accuracy by the efficient projectile rifle rotary; no ejection, greatly speed up and continuous shots, simple structure and accuracy; equivalence to common guns and bomb-heavy and cost by 1/ 5, and validity when contamination or overheating. The invention also has advantages of more efficient popularization of rifle technology in tank gun, and even mortar-asy pre shrink of the expansion end to trail-easy reduction to the expansion, expectation to help the mortar shoot the helicopter tail, for the gun-launched missile, being capable of reducing the rigidity of the guide shell and even helping the gun shoot with a fixed wing missiles.

Description

The close thorax formula of tail that expands does not have the ejection grenade
Technical field:
A kind of series property raising shooting firepower of the present invention and the light again reliable weapon of the degree of accuracy are applicable to infantry's air defense and antitank.
Background technology:
Order is taken aim at the most effective choosing of weapon; Beyond doubt rifled tube is penetrated firearm---but it has ejection to make mechanical complicated heaviness move again during because of shooting more unreliable---for subtracting these troubles; In recent years appearance such as Germany crosses to mould attaches caseless cartridge, and cost is many, but all incrustation is difficult to be popularized because of being prone in the rifle; Other has tank gun to abandon the good fortune pipe and simplify, but has lost range and accurately greatly.
For developing the long-range again firearm accurately and reliably of lighter Lian Yi, the present invention provides the close thorax formula of a kind of bloated tail not have the ejection grenade.
The present invention solves the technical measures that its technical problem adopts:
Let the bullet and the propelling charge cartridge case disjunctor of bullet, its main body external diameter and transmitting tube internal diameter adopt more active loose being slidingly matched to reduce resistance---in addition the gunny contaminated or overheated after still can effectively work.1 to 5 millimeter Duan Ze of this bullet tail causes only has be expanded into outside the sheet copper shell tubaeform---its big footpath should tight interference fit in the transmitting tube internal diameter---not only can bear striker percussion power, but also can be under the effect of percussion firepower still tightly during easy relative translation seal to connecting the rifle unoccupied place; Must be than with the also shooting more at a high speed of the heavier bullet of other bullet of bore even more effectively release to internal heat---transmitting tube is beaten hot when some is swollen, and still can keep this effect.And the bloated tail of this bullet very easily is embedded in the rifle seam and make bullet more effectively produce the rotation of good fortune formula to increase the degree of accuracy.It need not to withdraw from shell case [propelling charge cartridge case] again, so the tubeization associated mechanisms increases firing rate again greatly.This bullet is prone to cause basic complete directly cartridge form again, simplifies shape, and the utmost point is convenient to cooperatings such as magazine, even uses a funnel just to be prone to be high speed; The burst-firing ammunition feed subtracts fault and weight greatly.Under equivalent condition, estimate the weight and the cost that can help firearms and bullet and reduce about 1/5.
And for mortar, this bullet tail that expands can close up earlier to the tail that contracts that resembles the roundlet taper type, cause it than usual the person more be prone in gun muzzle, reach percussion apace to downslide.This tail that contracts is prone under the firepower effect, be reduced into the tail that expands again and goes to be fit in the gun tube that can contain rifle and penetrate.Under the suitable prerequisite of other condition, estimate and to make this mortar range increase about 1/3 and more accurate; Even comparable U.S.A must be superior to smooth bore formula tank gun and unguided missile in short tube howitzer, must more be applicable to the top of attacking enemy's tank or bottom [after asking for an interview " the antitank top bullet of attacking of variable land mine formula "].And the penetrating height and also can heighten of this bullet even can have been made aircraft [especially helicopter]--see for details follow-up " but barrage mortar ".Tank gun also should be imitated this.
The invention has the beneficial effects as follows:
1, innovation is applicable to that Chinese armed forces blazon the honest and clean firearm of a large amount of light and handy letters with the man advantage and remove to resist stealth aircraft, unmanned plane, cruise missile, helicopter and bulletproof jacket etc., wins To win local wars under modern, especially high-tech conditions..And the heavy mortar of terrorist's inconvenience storage those several myriagrams of utilization reaches heavier weapon and is difficult for being benefited.
2, reliable, few fault relies on high-tech and Precision Machining less, is suitable for China's Industry especially and produces and make and free and easy is careless uses for many compatriots.And can obviously reduce or remit disturbed by high-tech.
3, economize line, material-saving energy-conserving and environment-protective and subtract electromagnetic radiation, heavy metal chemistry and electronics intelligence greatly and pollute.
Description of drawings:
Further specify below in conjunction with accompanying drawing and embodiment:
Only a width of cloth figure is that sketch map is made in the work when not having the ejection grenade and being used for mortar of the close thorax formula of bloated tail that the present invention proposes, and engineer's scale is 1: 5.
Among the figure: 1, at the projectile ball; 2, detonation thing; 3, box hat; 4, copper sheet; 5, bloated tail; 6, gun tube; 7, bullet flies track; 8, at the bottom of the bore; 9, packing box; 10, lid; 11, the tail that contracts; 12, propellant powder; 13, treat the projectile ball.
Specific embodiment:
When no supplemental instruction, each things all can be correlated with referring to mortar in this example.Gun tube 6 inwalls preferably have rifle [can be referred to common firearms].Its bullet extends the short round tail end from the isometrical disjunctor of bullet middle and produces cylindric box hat 3 to hold propellant powder 12; Wrap tightly to be as thin as outside the box hat 3 and just can satisfy the copper sheet 4 of following demand [estimating about 0.05] as far as possible and extend 1 more backward to 5mm than box hat 3 to 0.2mm.This bullet is called when not launching treats projectile ball 13, and it is preferably with tail posture up upside down at ordinary times, is being contained and the top adds lid 10 good seals of anticreep by packing box 9 dresses of protection against the tide, and is firmly protecting projectile tail and propellant powder 12 to remain stationary as far as possible.This treats the tail 11 that contracts that the tail end of the copper sheet 4 of projectile ball 13 should be compressed into overall diameter and diminish [only otherwise produce radially evagination just allows some wrinkle]; The external diameter at other position of this copper sheet 4 is then comparable slightly smaller with the bore flying pig, and its manufacturing tolerance can be relaxed, and is economical in order to being prone to make; And let it more be prone to fast to slide at the bottom of the bore 8 from gun muzzle.So far reach to pulling the trigger propellant powder 12 and become detonation thing 2; And heat goes to form leak proof seal as far as possible with gun tube 6 endoporus towards be expanded into tail 5 to the tail 11 that contracts; Make detonation thing 2 cloaks keep up strength and remove to promote bullet and become, and be limited by the rifles in the gun tube 6 and fly track 7 by spiral helicine bullet and penetrate at projectile ball 1.Plasticity because of this copper sheet 4 is much better than other grenade in order to cooperate long one section the rigidity body [even as the same with non-rigid sealing ring person] of anti-gas-leak in the firearms, so the resistance of the Bi Gengli sealing the minimizing again relative gun tube slippage of bullet again.The practical thickness of other thing and copper sheet 4 then can be by following next preferential.In a word:
1, the close thorax formula of a kind of bloated tail does not have the ejection grenade, and the weak ball that the tube portion disjunctor of its bullet and dressing propellant powder constitutes is penetrated in gun barrel with the tail end interference fit again.Extend box hat 3 by what gun barrel or gun tube 6 were launched backward at projectile ball 1 head disjunctor; The propellant powder 12 that can become detonation thing 2 in dressing; The outer copper sheets 4 that wrap tightly again of box hat 3,4 of copper sheets than box hat 3 extend more backward 1 to 5mm and the tail port swell and become the bloated tail 5 of interference fit to appearance with gun barrel or gun tube 6 endoporus; This appearance in other part of projectile ball 1 except that the tail 5 that expands then becomes matched in clearance with gun barrel or gun tube 6 endoporus.
2, bullet by being stuck in the resistance that forms in gun barrel or the gun tube 6 with expanding tail 5 interference fit formulas, and in the time of should guaranteeing that this bullet receives the thrust of the two times of values of percussion power that are not more than its suffered striker in the back, the corresponding displacement of generation is not more than 2mm; And when this thrust increased to greater than 5 times of percussion power, corresponding displacement then should be greater than 9mm.
When 3, having the bullet of bloated tail 5 to be used for mortar, be to fade to its bloated tail 5 compressions in advance not hinder this bullet tail 11 that contracts to downslide the gun tube 6 of mortar in.
4, choosing only is that the thickness of copper sheet 5 is specially got different value equably between 0.05 to 0.2mm; But other situation try one's best identical 9 or more pieces of bullets carry out equivalence trial fire respectively, record range farthest the one-tenth-value thickness 1/10 of the corresponding copper sheet 5 of person go to instruct and produce this type bullet in batches.
