Description

To the solution of current firearms frequent high temperature just before a battle time
Technical field
On the basis of existing technology, by changing and improving, manufacture a kind of novel bullet and shell, cater to smooth bore technology, and be replaced in rifling technology, to eradicate current firearms a series of disadvantage such as frequent high temperature just before a battle time.
Background technology
Empirical evidence, makes bullet spiraling, can improve its hit rate.This point has been accomplished in the rifling invention of the 15th century, and 500 for many years, and it once played very large military affairs effect, obtains extensive accreditation and the application of the mankind so far, be described as the soul of firearms.Its unique advantage, be to make bullet when launching, spiral flies on axial line, makes it than being easier to hit.
But, to presently, the acquisition of this spiral effect, causing high temperature, interrupt continuously, lose lasting, reduce initial velocity, impel bomb tube old and feeble, weaken bomb tube intensity, high consumption machine power for cost.
Motor-drivenly to load and ejection, it is the main technical characteristic of modern armament, it greatly increases the tranmitting frequency of firearms, to its application, eliminating in the past the process of fine sight one to one, is all generally strafe with feeling, getting the upper hand of to campaign, except strategy, depend on the lasting and intensive of firepower, make it fatal or cause injury among thrumming.
At this moment rifling technology, not only seems unnecessary, and how sickly seems, is not the soul of firearms already, but the jinx of firearms.
Once Modern War repeatedly, such as World War I, World War II, in get over war, beautiful Yin war, demonstrate this point all repeatedly: rifling technology, it can only be applicable to, and craft is loaded, the transmitting of that slow rhythm of manual ejection, such as it is applicable to " three or eight " formula rifle and sniper rifle and so on, and the Mobile launch of high frequency cannot be applicable to, such as it is not suitable for heavy machine gun, light machine gun, tommy gun, antiaircraft gun, automatic rifle, repeater and so on.
War always, in the majority with hard fighting, time just before a battle, hostile both sides, need, by gunpowder emitter, to need by the quite a long time, implement continuous print and hit, carry out the trial of strength of firepower each other to it.
Owing to having continued to use rifling technology, under the effect of of short duration (about 2 minutes) high-frequency emission, bomb tube is easy to occur that high temperature soars, even can be aglow, bomb tube now, cannot be competent at that it is continuous, beat again and just there is no quality, even there is the danger of bombing bore, so, get to the bullet number (about 1000) of regulation, just need to change gun barrel, only 2 minutes, force its interruption too early continuously, and cannot hit and put in place.
Because be subject to the restriction of high temperature, cause and be badly in need of at the moment beating, the passive situation of beating again cannot be continued, although this moment burning with anxiety, but how must not, replacing bomb tube of have to lifting fire, every the replacing of 2 minutes needs once.Due to easy heating, have to constrain and beat, extend shooting time with fixed fire fork-like farm tool used in ancient China, worrying that bomb tube is rubescent, fear to change bomb tube again, is not situation very critical, thatly detain the rapid fire at full capacity that trigger is not put, almost not too dare use because with soon " extremely " soon.
The formation of this high temperature, for rifle, is due to when of short duration high-frequency emission, the heat discharged during gunpowder explosion, and the heat produced when adding that bullet spiral goes out thorax, with the dry friction of thorax wall, both heat sums act on the cause of bomb tube.But, the heat that this gunpowder discharges very high although (about 3000 DEG C), but flame lingering period of short duration (about 0.06/s) very, this period of flaming is to the foreign matter surface hotness that gives, be equivalent to by the nearly fiery a brief period of time of oxygen burning torch of firing and mistake, its hotness is very low, moreover has quite a few heat, is taken away when ejection by shell case.So the phenomenon that current bomb tube high temperature soars, mainly caused by dry friction, specifically a bit says, time mainly owing to squeezing out thorax in bullet embedding rifling groove, the temperature that continuous high frequency dry friction produces causes, and it is in occupation of more than 80% of this stagnation temperature.
As can be seen here, continue to use rifling technology and cartridge chamber and lack lubrication, be that two of current bomb tube produce warm arch-criminal greatly, if this two problems does not solve, cause the frequent high temperature of bomb tube to be inevitable, Yin Gaowen and bring out a series of disadvantage, be also difficult to avoid.Scrapping of many firearms, all relevant with temperature, the overwhelming majority is scrapping due to bomb tube, and causes the firearms of whole whole door to scrap.
Bullet embeds in rifling helicla flute and goes out thorax, although it can make bullet obtain vrille, improve hit rate, but for smooth bore technology, because rifling technology adds rubbing angle and area, when needs are launched lastingly, the high temperature that it not only result in bomb tube is frequent, forces continuously too early interruption, and adds resistance when going out thorax to bullet, the negative effect initial velocity of bullet, makes its range have a greatly reduced quality.
How could effect a radical cure the defect that this high temperature soars, this topic, be very heavy, and it entrusts to the care of the hope of several generations, and for these years, the mankind have spent all scheming for it, have racked brains, all of no avail, troubling so far.
In first time and World War II, the mankind once did a lot of effort for it, showed very positive.Such as fill water round bomb tube with water tank, or arrange a little fin in the periphery of bomb tube, or increase the thickness of bomb tube, fork-like farm tool used in ancient China improves its thermal capacity etc.But for the third world war of the unknown, the mankind, to its attitude, are much worse than in the past, the technology of being lowered the temperature at present, basic identical with World War II.In the environment of long-term peace, under being all the phychology of beating like this, this problem in the urgent need to address, does not just arouse enough attention, lack that just before a battle time serious hope.
Up to now, fact proved, the mankind are taken stopgap measures not effect a permanent cure, do not solved thoroughly from source, so, just can not there is its substantial breakthrough, on small scale by repeatedly, although alleviate to some extent, be all an utterly inadequate amount, of no avail, just before a battle time, final or unavoidable high temperature is frequent, and replace tubes is continuous, even makes too early retired of its firearms.It can be asserted that, as long as continue to use rifling technology, just cannot prevent bomb tube high temperature and soar, be its all effort, all can seem pale or negligible.
It has had the developing history of more than 500 year, and through the years that this is long slowly, the mankind, in this problem of process, show very puzzled, have no alternative, make them during more than 500 years, this change that disappears.Seem most effective method at present, is only change bomb tube, or accelerate to change bomb tube.And sent out the bomb tube of high temperature, utilization repeatedly again after being cooled, this behavior, not only delay opportunity of combat, encouraged enemy firepower, destroy fight mood, and no matter its precision or hardness, all cannot restore, during transmitting, therefore initial velocity and the trend of bullet all can be subject to very large negative effect.
The rifling technology continued to use at present, under continuous high frequency effect, the high temperature that result in bomb tube is frequent, brings a series of defect, to a great extent, it weakens the blow speed of firearms when using under battle conditions and dynamics, and especially making it lose can persistence, this point, it is the maximum technological deficiency of prior art, also be the most fatal technological deficiency, be also in all age the most scabrous technical problem, and be an international ordnance common fault.
Weigh the advantages and disadvantages, be fact proved by above-mentioned, for continuing to use of rifling technology, will seem out-of-date, will seem inadequate, will seem and cannot adapt to current high frequency Mobile launch.
Why rifling technology still obtains doting on of the mankind so far, only has two kinds of explanations, and one is because the mankind have been muffled eyes by its minor benefit, ignores therefore and many defect of producing.Two is know that it exists drawback perfectly well, of no avail because in addition, the mankind as again cannot finding than its better spiral methods, reluctantly, have to be inadequate depend on rifling technology.
For its spiral, the mankind can put one's ass on the line as cost, and such obtained spiral, concerning current, loses more than gain really, does not have great practical value, because disadvantage is too many, with its use, not as need not, but have to use.
Summary of the invention
Bullet is rotating strike target, this imagination is correct, and be science, it meets law of nature, because object only has by spiral, just can find its axle center, and is not easy to depart from its axle center.Due to the advantages of spiral, so the mankind just hanker after this road, do not abandon all the time, it's a great pity and used mistake carrier.
Rifling technology is a kind of means of spiral, a kind of method, a kind of carrier, so, can not negate the effect of spiral because of negative rifling technology.Spiral is one independently passive effect, the method for its spiral is had various, spiral itself there is no mistake, but depend on whether the carrier of spiral is used appropriately.
Although opposing intensive group is not at present take man-to-man play, but adopt strafing of high frequency, but it is individual for fragmentary enemy, fine sight is one to one needed to hit, in campaign, the enemy of colony or individuality, all likely, say again, if bullet does not do spiraling, except misalignment, bullet probably can beat fall, so, as long as spiral does not cause high temperature, do not affect the lasting high-frequency emission of firearms, this spiral is necessary, useful, even can say, spiral is the soul (not rifling technology is the soul of firearms) of firearms.
The theory of mechanics of firearms, the theory of mechanics of similar general engine, it has piston equally---front have bullet, after have gunlock, have cylinder that---bullet is discharged cartridge chamber by---fire in a stove before fuel is added, have fuel feed system---gunpowder, have mechanic effect---cartridge chamber, to have igniter.So it is a complete motor-driven system, to its safeguard method, should be the same with other engine, and ensure seamless, the glossy cunning of the pure circle of cylinder bright be the most basic, otherwise, just cannot maintain it and work normally.The high temperature of current firearms is frequent, not competent transmitting lastingly, its underlying cause, is exactly exactly that so one is that cartridge chamber has trace, and two is that cartridge chamber loses profit.
If not employing rifling technology, but popularization and application smooth bore technology, its consequence will exhaust can be different.Therefore bomb tube not only can be processed simply, and can bear lasting high-frequency emission.Due to reducing of friction area, time just before a battle, bomb tube heat can not would not prop up as today, and bullet also can because of the minimizing of resistance, and fly farther, and also can obviously extend its service life, result of use also can significantly improve.Although application smooth bore technology also can produce certain heat, the heat produced than application rifling technology is much smaller, before using machine oil, wants little by 30% at least, after using machine oil, wants little by 70% at least.
No matter smooth bore technology, except not making bullet and rotating, from which angle get on, be obviously better than rifling technology, so, as long as adopt this method, therefrom obtain new spiral, fork-like farm tool used in ancient China makes up this defect, and smooth bore technology just has the ability to be replaced in rifling technology completely, and its disadvantage is disappeared completely.
This method is exactly for above-mentioned actual conditions, is devoted to smooth bore technology to replace rifling technology, obtains spiral, bullet namely will be made to be rotating flight, make bomb tube can not produce high temperature because of the rotation of bullet again by other approach.
This method have employed the operation principle of windmill, makes bullet under the effect of " wind ", natural starting spiral, and the spiral technology new-type by this, is replaced in rifling spiral technology.
Bullet arranges a little spiral wind groove, and when bullet is when obtaining initial velocity, the high pressure draught produced when utilizing bullet to pass through air, suppresses in spiral wind groove, as windmill windward, forces it to rotate.By the High Rotation Speed that it has obtained at initial velocity (about 0.3 second), the middling speed that inertia flies in bullet and end speed, that is afraid of that this bullet is at the end of one's resources to overcoming, and also can land rotation one Chen Zi.That is, its rotatory inertia length more resistance to than flight inertia.
From surface, this seems unlikely, because this wind groove is subject to the restriction of bullet volume, and suitable narrow of its wind area.But, when an object (no matter large or small weight) is shifted with the speed of km per second, nature can produce huge passive air pressure and air-flow, this huge air pressure and air-flow, under the effect of spiral wind groove, can rotate by unsettled startup bullet completely, and in the initial velocity stage, due to relations such as angles, its rotary speed is more faster than rifling rotary speed.
This effect, can be verified by a slight test fork-like farm tool used in ancient China: the arrow of adder tongue herb is made warhead shape, is penetrated after engraving several roads spiral wind groove with bow, after Camera location shooting, slowed down 100 times and observe it dynamically, at this moment will find, arrow is rotating flight.
Although spiral wind groove is when passing through air, can produce certain resistance to the flight of bullet, the resistance produced than rifling friction screw is much smaller, because the former is thorax, outer unsettled startup rotates, and the latter extrudes rotation in thorax by force.One object, once rotate, will naturally find axle center and even be not easy disalignment.
General gunpowder emitter, its range can reach km, even thousands of rice.Hypothetical target is (about 50 meters) within the range region of initial velocity, and during shooting, that is afraid of bullet non rotating, equally easily hits the mark.This is not only that mainly because in the range period of initial velocity, due to the cause that speed is exceedingly fast, the flight path of bullet, necessarily two one straight lines, that is, in this time period, bullet can not make parabola because distance is near.So the object of spiral is not in order to the fastest initial velocity, in order to make parabolical end speed, but in order to middling speed, neither be to maintain the follow-up phase of bullet at initial velocity, this section of straight line extended.This method is exactly make use of the time period that initial velocity do not need spiral, obtains enough spirals, and inertia, in needing the subsidiary end speed of the middling speed of spiral, makes this section of straight line under the effect of spiral, obtains relative prolongation.
The words popular with sentence are said, the object of spiral, are to make bullet in the period that should take the air line, and help bullet to take the air line, and for making parabolical end speed after effective range, although spiral inertia still exists, lose the meaning of spiral.
To the application of this technology, on the one hand, because this method has catered to smooth bore technology, so smooth bore has ensured the complete of cartridge chamber inwall, make to which increase intensity and fineness; On the one hand, because this reducing friction area, reducing the temperature of about 70%, improve the initial velocity of about 20%, made favourable condition to unlimited bullet amount, high frequency high-quality transmitting Chong; On the other hand, due to the effect of wind groove, during transmitting, this bullet not easily runs through, and easily remains in the body of target, even if can be taken out, also makes its grain be subject to second time injury (war is cruel, pardons me cruel) unavoidably.Fact proved, the residual ratio of bullet runs through more has lethality.
This novel bullet with wind groove and shell, except bullet seems that except difference, its overall specification is constant, so its is applicable to the application of current rifling technology equally, under the effect of machine oil, during transmitting, the temperature of bomb tube is than original at least low by 40%.That is, before not having popularization and application smooth bore, its allows the existence of prior art, and is of value to and is mated application.Smooth bore and rifle sharing it is only the final transition comprehensively implementing smooth bore technology, only have this novel bullet and smooth bore with the use of, be only the wisest, optimal.
To its enforcement, as long as involve in few energy and cost, just effecting a radical cure defect and drawback thereof that this high temperature soars up hill and dale, just can realizing 24 hours sequential filming and without the need to changing gun barrel, and all the time energetically.Launch 500 calculating with single tube per minute, after applying this technology, single tube sequential filming bullet amount can be about 720000-1000000 and sends out, and is more than 1000 times of the disposable maximum permission emission measure of present single tube.This difference seems astonishing, incredible, has the suspicion of making an overstatement, but not at all surprising, also need not doubt, and all are all in nature.
Because this is just the same with limousine, normally can walk one thousand li a day, otherwise just difficult to move even one step; Engine has added machine oil, just can run quickly ten thousand li, otherwise, travel several kilometers it to be scrapped thoroughly, firearms belong to a reason together with it, as long as operate in strict accordance with mechanically actuated regulations, can persistent work, will be natural, without any mystery.
If done the test of destructive heatproof, firearms just as general engine, can work for a long time without a break, and transmitting in continuous 48 hours is no problem, and the time even maintained can be longer, time just before a battle, and not replace tubes of substituting.And prior art, with the replacement cycle of 2 minutes, can only change gun barrel frequently, by contrast, both differences, are as different as light from darkness.
Detailed description of the invention
On the basis of existing technology, by changing the shape of bullet, bullet is made to obtain new-type spiral; By improving the structure of ammunition, cartridge chamber being obtained and moistens fully, being manufactured a kind of novel bullet and shell, cater to the smooth bore technology of firearms.This be a set of very complete, very effectively, the economic cooling profiles of bomb tube very reliably, one is wind groove, and two is machine oil, and three is smooth bores, these three kinds of key elements, indispensable.Because smooth bore technology is inherent technology, as everyone knows, do not state at this, stress the preparation method of bullet wind groove and the using method of machine oil below, and the many benefits after it is implemented.
One, the preparation method of bullet wind groove:
The geometry of bullet is various, and its difference in appearance is larger.But have common feature between them, that is exactly one, and other end is little greatly, and be except cylinder except bullet embeds that section in shell case, its exposed part is all conically, and this taper all expands shape with evagination arc.
This method make use of the great part of this evagination arc exactly and makes " fan blade ", arranges the consistent spill wind grooved ring of minimum three roads (can the be more) degree of depth, width, length, spacing, angle around bullet.
Its angle, the opinion because of bullet, in general, greatly between 30-50 degree, its best angle, needs by determining, because the bullet of all kinds of model by class test, there is oneself spiral angle applicable, so just unified global angle can not be had, but can affirm:
1, the size of angle, the spiral torsion flown to bullet, helix speed, spiral inertia, screw traction power, flight resistance are directly proportional; Be directly proportional to the volume of bullet, body weight, tolerance.
2, the length of bullet, is inversely proportional to the angle of air spiral vortex.
3, the size of vortex angle, the convoy barrier coefficient flown with bullet is inversely proportional to.
4, the hand of spiral of wind groove can be left-handed, also can be dextrorotation.
5, the depth, width, the length of groove, is directly proportional to the volume of bullet, body weight, tolerance.
6, inwardly about there is inclination on one side of groove wind-engaging, and another side is also toppled over towards same direction, its angle of inclination, more better in bottom land close to level, sawtooth like shape.
7, spill wind groove, be this bullet peripheral the arc give prominence to is great partly does parting, style groove outside the straight flange triangle remaining on this bullet cutting plane inherence.Plainly, be exactly by this bullet Zuo Ge center sectional plain-view drawing, after finding out wherein maximum quadrantal (spherical) triangle, by remaining part style groove, its degree of depth can only this triangle proper, and can not injure this triangle, otherwise its spiral torsion and flight resistance can be caused synchronously to increase.That is, the bottom land of this spiral wind groove, should with this triangle for core be wound around, because only in this way do, just can make its spiral force, flight forces and the therefore air-swirl produced, remain on optimum state.
8, the arc of spiral wind groove expands wind surface, and be fade away in two, centre is projection gradually.
9, this bullet, not affecting initial velocity with under the prerequisite of invading shear force, according to spiral or aesthetic needs, can deliberately spy do.
10, bullet concentricity wants high, and surface requirements is smooth, the specification of wind groove will be equal to, evenly, smooth.
11, in order to reduce the friction area of bullet and thorax further, increase air pressure to the active area of projectile tail, improve the air pressure of gas in shell case (holding one's breath), spiral should be wound around from the top of bullet (can apart from top a bit of distance), stop until this bullet embeds that section of cylindrical length 3/5 in shell case, and make bulb-shaped recess at the final section of bullet major part, the periphery of depression becomes sharp edge-shaped, to be adjacent to cartridge chamber at explosion time projectile tail as umbrella, prevent gas leakage, its degree of depth equals or is about less than that section cylindrical 1/5, after this bullet embeds Case mouth end, the helical groove again shell case being complied with bullet is riveted tightly.
12, the manufacturing process of this wind groove can be forging forming, also can be cast molding, also can be that milling is shaping, also can be that broaching tool is shaping.It makes simple, easily shaping.
13, the contact surface of bullet and cartridge chamber, material difference each other, suppose that the material of cartridge chamber is steel, bullet embeds that section of cylindrical surface (with the contact surface of thorax wall) in shell case, preferably similar to the material of piston, as copper, aluminium alloy and so on, other parts material is not discussed, or more hard better, or more heavy better.
This novel bullet being provided with groove on bullet, during transmitting, has benefit many as follows:
1, bullet makes spiral outside cartridge chamber, and this spiral can not to cartridge chamber generation effect.
2, due to this spiral angle than rifling spiral angle greatly to tens times, easily form spiral more at a high speed.
3, concavo-convex due to wind groove, the surface weight of bullet is distributed lose even, under High Rotation Speed effect, convex part can produce centrifugal force, makes gyroscopic effect more sturdy.
4, because wind groove can produce spiral vortex at the volley, this vortex type, like the protective barrier of umbrella, for the flight along the line of bullet escorts, makes the more difficult disalignment of bullet.
5, under the effect of wind groove, when spiral inertia is greater than flight inertial time, its spiral effect to the end speed initial stage of bullet flight, can play a part traction, makes this section of straight line about have growth.
6, due to the effect of wind groove, bullet is easily cut, and be not easy used wearing.
7, due to the effect of wind groove, make the ruins in cartridge chamber under the scraping of groove, easily discharge outside thorax.
Two, the using method of machine oil:
The normal work of any engine, all be unable to do without the support of machine oil effect, be machine oil is the service which providing lubrication, sealing, heat radiation, cleaning, noise reduction, only have this five superior greatly, just can guarantee the normal work of engine, of all times, all trades and professions, size are complicated and simple, absolutely not make an exception.
Since firearms are complete motor-driven systems, possessing the condition that general engine should possess, use machine oil that just should be appropriate, otherwise be exactly destructive operation, to the harm that plant equipment is brought, will be destructive.Machine oil is to the lubrication of cartridge chamber, and be not not essential, and be have, say from mechanical sense, it is even even more important than the spiral technology of bullet.
Owing to can not find the place that can hold machine oil at firearms high-speed motion position, have crankcase, be difficult in this point unlike other engine, this point is hidden deep, is not easy to be perceived by people.In the scheme of all feasibilities, such as by oil pump, sprayed by recoil extruding, by nature drippage etc., and to utilize shell case to make its container be best preferred, the performance to machine oil effect, implementing on each bullet, during transmitting, allowing its disadvantage go out from originating from.Bullet has oil to have, and has played oil complete, without the need to additionally carrying machine oil.
The container of machine oil is determined by means of after shell case, then solves the isolation between the two of gunpowder and machine oil and proportioning problem.Machine oil is aqueous body, and gunpowder is very dry particle, if be placed directly in together by both, is bound to " incompatible as fire and water ", so need, by the method for isolation, it definitely to be isolated.Under the prerequisite keeping shell case former state, there are three kinds of alternative partition methods:
One, in its ratio, by barrier film, machine oil and gunpowder definitely to be isolated.The edge of this barrier film tumbles in diaphragm ring, similar rice huller screen shape, and the external diameter of ring is equal to shell case internal diameter, metal material, is combined into a complete entirety with shell case; Bao Yuehao got over by this barrier film, can play buffer action just, metal material, and its thickness is generally at 2-3 micron, if its thickness is more than 5 microns, needs on this diaphragm plate, to make " rice " font indenture, easily to break at explosion time; According to both proportional quantities, determine the position of this film in shell case, among the bottom press-in shell case of shell case; The fire in a stove before fuel is added is contained in one and threadedly covers, and gunpowder is from after the bottom of shell case loads, and it is fastening, and machine oil directly pours into from Case mouth.Position residing for them is, wrap with straw under, by barrier film oil in, bullet waist system sealing ring is sub in upper sealing.This is that so-called barrier film loads method.
Two, in its ratio, machine oil is made the small particle of fish glycerine pellet, polymer wraps up, embryo is thin, definitely ensure the fire in a stove before fuel is added can ignite at any time gunpowder prerequisite under, this granule and gunpowder are at will mixed, or being placed by classification on gunpowder, bullet is at upper sealing.This is that so-called particle loads method.
Three, in its ratio, machine oil is wrapped in a thinner polymer container, medicine under, oil vessel in, bullet is at upper sealing.This is that so-called container compound loads method.
Above three kinds of methods, any one is all effective.In the ruins amount that explosion time produces, very little, namely produce and namely arrange, do not affect the enforcement to it.
Because machine oil will occupy certain space, this just needs originally to be filled with the gunpowder in shell case, vacates certain seat and gives machine oil, because their proportional quantity is 25-30/1, suitable limited in space occupied by machine oil, also machine oil can improve its air tightness, goes the minimizing compensating powder volume, so, seem and decrease ignition charge, in fact can not affect the original power of gunpowder, due to the sealing function of machine oil, its gun pressure only than original higher, and can not be able to reduce.
For the proportional quantity problem of gunpowder and machine oil, can carry out examination with reference to the ratio of two stroke engine blend gasoline and join, this blend gasoline, mixed in its ratio by pure gasoline and two-stroke special engine oil, its ratio is generally between 25-30/1.Now gunpowder is considered as pure gasoline, the two stroke special engine oil of same use, carries out examination in its ratio and joins.
For the problem of storage life, record according to interrelated data, present bullet and the storage life of shell, when sealing, the storage life of machine oil substantially can be synchronous with it generally at 8-10.Say, because implement simple to it, as long as put several oily balls in every shell case, manufacturer is instant to be filled again, so, about the problem of storage life, do not affect the enforcement to it.
This novel bullet after machine oil is housed, during transmitting, has benefit many as follows:
1, due to the humidity of gas, the surface of thorax wall and bullet can be moistened fully, its contact surface is lubricated, remain on the state that glossy cunning is bright from start to finish, the phenomenon of " scuffing of cylinder bore " can never be there is, because bullet is stained with machine oil, bullet coefficient of friction when passing through air can being reduced, being more of value to the far accurate of bullet.
2, due to machine oil continually, supply according to quantity on time, explosion time, along with the ejection of mist flow, can take away cartridge chamber heat in time, and the ladder avoiding temperature rises and accumulation, makes transmitting all the time energetically.
3, due to the characteristic of machine oil, although explosion time defines mist state, its amount of its matter also exists, and it constantly can fill up the gap between bullet and thorax, effectively increases gun pressure, improves the initial velocity of bullet, makes bullet Cheng Gengyuan.
4, high pressure draught through moisture constantly washes away, and its all ruins can be discharged outside thorax in time thoroughly.
5, bullet and thorax are under the effect of machine oil, can coordinate more tight, absolutely not have the phenomenon of " engine knock ", and both are the frictions between oil and oil when rubbing, can not produce the sound.
6, due to the rising of gun pressure, reaction force (kick) also along with increase, as long as the hardness of the former recoil check spring of enlarged relative, just can shorten the gunlock reciprocal time, make tranmitting frequency higher effectively.
7, can increase machine oil on original basis, the cost implemented it is very cheap, and does not affect original production routine.
8, in sum, application machine oil benefit is many, this for prolonged mechanical service life, improve firearms fighting capacity, save expenses of military expenditure,
There is positive effect.
Above to the statement of scheme, it is longer that it compiles width, and but very simple during enforcement, as long as at bullet Shang Keji road groove, put several oily balls in shell case, is exactly a novel bullet, is launched with smooth bore bomb tube, just can get a desired effect.
