Abstract

The invention relates to a caseless cartridge. The caseless cartridge is composed of a propellant powder column, a primer, a warhead, starting powder, a dampproof wrapping body and an isolating heat dissipation wrapping body, wherein the warhead is composed of a head cone, a cartridge belt, a tail protrusion or a missile wing and a tail post and is fixed into a center hole of the molded solid propellant powder column. The tail post of the warhead abuts against the primer. The warhead has the functions of a traditional bullet primer platform and an anvil. The starting powder with the burning rate higher than that of the propellant powder column is arranged in front of the primer and behind the tail protrusion or the missile wing to make percussion of the cartridge be stable and reliable. The dampproof wrapping body is made of a water-repellent organic thin film material and wraps a cartridge body completely to achieve the effective dampproof effect, and accordingly the misfire rate is reduced. The isolating heat dissipation wrapping body is made of metal foil with good heat conductivity so that temperature rising of the cartridge body can be effectively delayed, the high-temperature resistant performance of the cartridge body is improved, and adhesion between the dampproof wrapping body and a cartridge chamber is effectively isolated. The caseless cartridge is compact in structure and low in weight; the firing distance and penetrating power are increased, and the damage effect is improved; and the underwater using effect of the cartridge with a spiral wing is remarkable.

Description

A kind of caseless cartridge

Technical field

The present invention relates to a kind of caseless cartridge, particularly relate to a kind of caseless cartridge for muzzle-loading projectile rifle.

Background technology

Caseless cartridge does not i.e. have a bullet of shell case, be strictly speaking launch after the bullet of a small amount of residue, the most relatively reliable implementation method First propellant is bondd by flammable binding agent, be then molded into a firm propellant powder cylinder, then bullet and the fire in a stove before fuel is added are embedded in medicine respectively The two ends of post, powder column replaces shell case to become the carrier of bullet.Owing to this bullet eliminates the shell case of conventional bullet, so single-shot weight is big For alleviating, the weight of 100 caseless cartridges, be only about equivalent to 20 weight sending out bullet conventional, therefore soldier in wartime can carry with More bullet, is effectively increased the lasting fight capability of individual soldier.But the caseless cartridge occurred at present has two big critical defects, and first is certainly Combustion problem, when rifle is launched continuously, the temperature of cartridge chamber can drastically raise and can not dispel the heat in time, and bullet launches powder column with regard to direct and bullet after entering thorax Thorax contacts, and result will make bullet spontaneous combustion launch and cause danger when cartridge chamber temperature is higher than cook-on temperature, and this main reasons is that The reason of rifle, but the improvement of bullet is the most extremely important.Second is moistureproof problem, owing to bullet will be exposed in natural environment without shell, powder column, Long-term storage is made moist unavoidably, makes the misfire rate of bullet be substantially improved.Owing to the problems referred to above are solved the most well, now Caseless cartridge in the world does not has any country and equips use, and systematic study is the coldest.Bullet is the final embodiment of firearms power, The performance of fighting efficiency can be directly affected.

Summary of the invention

Because the situation of prior art, it is an object of the invention to provide a kind of for muzzle-loading projectile rifle, solve spontaneous combustion to greatest extent With moistureproof problem, penetrativeness and damage effectiveness and flight stability be better than the caseless cartridge of conventional bullet, and do not changing bullet monnolithic case In the case of physical dimension, use under water and also have good performance.

In order to achieve the above object, the present invention provides a kind of caseless cartridge, by propellant powder, the fire in a stove before fuel is added, bullet, startup medicine, moistureproof bag Cover body, isolation radiating cladding composition；Described propellant powder be moulding after have the flammable cylinder of band centre bore of rigidity；The described fire in a stove before fuel is added is embedded in Launch in the centre bore of powder column one end；Described bullet is a big L/D ratio rigid body, or missile wing convex by nose cone, bearing band, tail, stern post are constituted also Penetrating transmitting powder column centre bore to fix, stern post offsets with the fire in a stove before fuel is added；Described startup medicine be combustion speed higher than launch powder column gunpowder, or shot shape or Moulding, it is placed in that tail before the fire in a stove before fuel is added is convex or after missile wing；Described moistureproof cladding is waterproof thin-film material, is coated with whole body completely；Described Isolation radiating cladding is the metal forming of good heat conductivity, and the waterproof thin-film material covering body is coated with completely.

The operation principle of the present invention is as follows: bullet stern post offsets with the fire in a stove before fuel is added, and warhead-containing body serves conventional bullet fire in a stove before fuel is added platform and the work of chopping block With, when the gunslinging pin impact fire in a stove before fuel is added, hitting power can be conducted to bullet by the fire in a stove before fuel is added, and bullet is with the bed knife in powder column and the inertia of self Gunslinging pin is had a counteracting force to converge the fire in a stove before fuel is added by power, makes the fire in a stove before fuel is added stably fire, simultaneously because the impact of gunslinging pin, warhead-containing body is also Obtain initial torque forward and initial velocity.First ignite after the fire in a stove before fuel is added percussion startup medicine being close to, owing to combustion speed is higher than launching powder column, Moment produces one high pressure launching in powder column centre bore, is first about to bullet and is forced into forward the skirt of gun barrel, goes to block the import of gun barrel, Large area is ignited transmitting powder column simultaneously, and bullet is released gun barrel by the gas producing more high pressure, makes bullet obtain high from mouth speed.

Owing to bullet has big draw ratio, so there being good stability in flight course.

When using the bullet of big pitch missile wing, bullet is acted on by barrel rifling in gun barrel, can pivot after leaving gun barrel, Make missile wing produce propeller effect, bullet flying distance can be made to increase journey, and particularly evident when this increasing Cheng Xiaoguo uses the present invention under water.

The waterproof thin-film material of moistureproof cladding mostly is the organic film of water repellent, and its effect has three, and first is moistureproof, due to Body profile is more regular, and entirety is coated with easily realization completely, and does not has sharp wedge angle top thorn coating not cracky, moistureproof efficiency High with reliability.Second is heat insulation, and the heat conductivility of organic material is the most very poor, and entirety just serves after being coated on body completely The effect of insulation.3rd is cooling, and the fusing point of organic material is low, and when being melted by exceeding the temperature of its fusing point, and thawing is To be absorbed heat, therefore the temperature rise to body has certain hysteresis.It addition, thin film to be first ignited when whole powder column burns, this is just Reduce powder column burning time high temperature hot flame to the isolation radiating direct ablation of cladding metal forming, prevent because of isolation radiating cladding metal forming Excessive melting and the sintering with cartridge chamber inwall that occurs.

The metal forming of isolation radiating cladding good heat conductivity, such as aluminium foil, Copper Foil.Its effect has three, and first is heat radiation, many Well known, burning often originates from a bit, stops heat to assemble the effective means being to prevent from being ignited on one point, after snapping in cartridge chamber, The mode contacted with cartridge chamber is based on dotted line, in time that the heat away on these dotted lines is the most crucial to preventing from being ignited, therefore, and heat conduction Good metal forming can effectively prevent the spontaneous combustion of body.Second is isolation bonding, owing to the organic film of protection against the tide cladding is heated and can melt, enters Will melt after entering high temperature cartridge chamber and cartridge chamber inwall adhesion, if at this moment this piece of bullet is fired, hang over the moistureproof covering material on cartridge chamber inwall Owing to the effects of reduced temperature of cartridge chamber inwall will not burn completely, can leave a small amount of residue, accumulation is many will tie up the position newly entering bullet； If this piece of bullet does not fires, stay cooling in cartridge chamber and will be bonded without method with cartridge chamber and exit, exit while hot and will also result in moistureproof cladding Breakage, so, the buffer action of metal forming is the most critically important.3rd is antistatic, is hit by a bullet due to use process and is intended between bullet closely connect Touching, phase mutual friction can produce electrostatic, and the easy static electricity gathered of the organic materials such as plastics causes a hidden trouble, electrostatic can be had by the covering of metal forming Peptizaiton.

Compared with prior art, the beneficial effects of the present invention is:

1. the caseless cartridge of the present invention, the metal forming using heat conduction good is external sheath body, effectively prevents heat to assemble on one point, The temperature making body be ignited improves, and the solution to caseless cartridge spontaneous combustion problems plays a key effect.

2. the caseless cartridge of the present invention, uses the waterproof and organic film material integral coating of water repellent, comprehensive does not stay dead angle to bullet Body is the most moistureproof, makes the temperature rise of body produce certain sluggish simultaneously, plays positive role to solving spontaneous combustion problems.

3. offseting with the fire in a stove before fuel is added due to bullet stern post, bullet serves the effect of fire in a stove before fuel is added platform and chopping block, when percussion every time more effectively, more Reliably, make misfire rate lower.

4. the caseless cartridge of the present invention is owing to have employed startup fast burn medicine, and bullet arrives gun barrel entrance in advance and effectively blocks it, The early stage preventing gases at high pressure leaks.Start medicine launching in powder column centre bore and can large area ignite transmitting powder column simultaneously, make transmitting powder column Increased flame speeds, and it is more complete to burn.

5. the big pitch missile wing bullet of the present invention is compared with other bullet, can be effectively improved bullet under conditions of obtaining equal initial velocity Shooting distance, its penetrativeness and damage effectiveness and flight stability are also improved.Its big pitch missile wing when especially the present invention uses under water The above-mentioned advantage of bullet becomes apparent from.
