Multi-caliber bullet and special purpose submachine gun

54
Submachine gun: yesterday, today, tomorrow. What parameters should have effective bullets for submachine gunswhose goal is the fight against terrorists? If the SHA-12 assault rifle has a striking effect due to the 12,7-mm caliber, is it possible to create something else based on data not only from modern technology, but also historical Sciences?



Model of a submachine gun chambered for with an H-shaped bullet in its trunk. Shop shot. Inside the front "superstructure" is the receiver of the store and the L-shaped pusher for cartridges, feeding them into the cylindrical swivel mechanism. In the back "superstructure" is a spring-loaded support for the store, which firmly holds it in its place. It also has a diopter sight. The bolt handle is connected with it by a system of plates that cover the hole in the receiver, so that dust and dirt do not get into it through it.

Tips from ancient burial grounds


In the past, the material where it was told about a bullet in the form of a disk with a sharp cutting edge, it was said that even arrow-shaped arrowheads were found in ancient burial grounds. In the form of a disk! That is, they were designed exclusively for causing a wide incised wound. But there were also known purely armor-piercing arrows, which did not rotate in flight. These tips were narrow, faceted, capable of pushing the rings of chain mail, or also narrow, but flat, shaped like a chisel or a chisel. These were already calculated to sever the rings of chain mail. Well, a completely flat tip reduced the possibility of rebound when hitting the target at an angle.


Submachine gun with magazine and butt. The reloading handle along with the shutter when shooting remains in place. It is connected by a gear with a swivel mechanism, and every time when the bolt is raised, it turns it by 90 degrees. At the same time, the cartridge gets inside it, which is pushed out of the store by the L-shaped lever.

It so happened that we look at the bullet to the bullet arms an extremely cylindrical shape, although previously square-shaped bullets were also known, intended for firing exclusively at “non-Christians” and “savages”.


View of the submachine gun on the right with a magazine installed on it. A tactical flashlight is installed on the front “superstructure”. Immediately behind the trigger fence there is a cartridge case, through which the spent cartridges are thrown right down, which is very convenient for the shooter. It will be difficult to remake such a submachine gun for left-handed shooters, therefore it is better not to take them to the special contingent armed with these BCPs.

Well, what if you create a cartridge with a high-speed bullet of increased punching action, which could, like the arrow of an ancient bow, rotate under the influence of the oncoming air flow? By the way, after all, there are bullet-impellers for smooth-bore hunting weapons. Moreover, it would be good to make it so that this bullet, without violating all the Hague and other conventions there, would be small in itself, but caused very large wounds, so neither the bulletproof vest nor the analgesic injections would leave terrorist no chance. A challenge for TRIZ, isn't it? To make a small one large, not rotating - rotating, moreover, so that the tip was very sharp, but so that there were no problems with sending such ammunition into the chamber.


A bullet with stabilizers opened and a cartridge next to it along with a bullet.


Bullet with the profile of the letter "H"


And what if you make a multi-caliber bullet N-shaped in its profile and equip it with a multi-vane tungsten-molybdenum alloy tip? Moreover, it is clear that not the whole bullet should be made of it, but only its combat part, and it should be connected so strongly that the bullet would not disintegrate in the human body in accordance with international conventions. Hypothetically, it may well look like a flat parallelepiped with the front part in the form of two interconnected ... "chisels", sharpened in opposite directions. Between them, a jumper that prevents the flow of air. Something similar was used in the ancient arrowheads. Because of the difference in the directions of sharpening, they flew, rotating in flight. But in our pool there are four more drop-down stabilizers, which in any case will improve the accuracy of its flight, regardless of whether it rotates or not. Thus, she has not one, but several calibers at once: horizontal caliber 22 mm (this is the width of the bullet itself); vertical caliber 24 mm; diagonal gauge (i.e. diagonal between stabilizers) 32 mm. The caliber of the body itself bullets 4 mm. With folded "wings" 7,6 mm. Length xnumx mm. The maximum diameter of a flat sleeve 25 mm. Length xnumx mm. For attaching a bullet to it, a narrower Dultse is provided, which includes a bullet with stabilizers folded and pressed against it. That is, if it rotates in flight, the inlet will be a diameter ... not less than 9 mm. If it does not, but it will be possible to achieve satisfactory accuracy at a distance of 24-33 m, again, like most modern machine gun pistols, we will get an opening in the shape of the letter “H”, also large enough to prevent any criminal activity , even the most notorious terrorist.


Shop with a cartridge on the feeder. On the right, there is a dust plate that closes the feeder from contamination when the magazine is attached to a submachine gun.


The cartridge turned out to be similar to a rifle and at the same time quite large. When the liner thickness in 9 mm 30 cartridges stacked in one row on each other, the 27 cm plus another spring and feeder should take it to the store, so the magazine for such cartridges protruding from the submachine gun from the bottom immediately turns it in an extremely uncomfortable weapon for the shooter. Therefore, a scheme was chosen with a horizontal location of the store, much in common with its installation on the German G11 rifle and the P90 submachine gun. But only it is inserted not in front, but on the left side. The cartridges are located in it vertically, with bullets down. Once inside the receiver, they are inside a special rotary mechanism of a cylindrical shape, with which each regular cartridge is mounted on the disillation line in the chamber.


Front "superstructure" with a front sight. You can clearly see the rectangular hole for feeding cartridges into the turning mechanism.



Rear "superstructure" with a diopter sight. Retractable stock shot.


Simple enough device


The receiver of such a submachine gun may well be a simple cylindrical shape, therefore the bolt to it is also cylindrical, on two springs and two guide rods. Well, let's say, like the old American M3. But in front of the barrel there is a rotary mechanism in the shape of a cylinder with a hole for a cartridge. The magazine is set so that its receiver with a cartridge on the feed tray is above it. The cylinder is connected by a connecting rod with a L-shaped spring-loaded pusher, which is located in the "superstructure" above the turning mechanism. When the bolt goes backwards, the cylinder turns and its hole is aligned with the hole for feeding cartridges. The L-shaped pusher pushes the cartridge from the magazine brackets, it falls down and is inside the cylinder. Moreover, inside his cartridge is additionally held by a magnet, so that when firing up, he could not fly out of it inside the receiver.


Once again a bullet close-up.


In front of the gate there is a rectangular protrusion with an extractor, which enters the cylinder bore of the turning mechanism and sends the cartridge into the chamber, after which the shot takes place. USM can be done and the trigger, passing the hammer with the drummer through the bolt, which will increase the accuracy of shooting. Although the shape of the chamber is simple, right behind it is a special “expansion chamber.” There is free space, and in front of the entrance to the trunk there are four protrusions resembling dozer blades, which, with their sharp edges, come under folded bullet stabilizers.


Submachine gun with extended butt. On its shop the latch and a dustproof plate is well visible.


Multi-caliber bullet and special purpose submachine gun

You can also install on it the collimator sight EOTech XPS3.


The liner contains a powder charge of two types of powder: 20% quickmatching and 80% slow burning, armored. When the primer ignites, the quick-burning powder immediately flashes, the pressure instantly increases and the bullet enters the barrel. The protrusions in the chamber straighten its stabilizers, they slide along their curved surfaces and fall into the side vertical channels of the letter “H”. Next begins to burn the main powder charge, which accelerates the bullet to the maximum speed. The front part of it is heavy, from a tungsten-molybdenum alloy. The back of the “parallelepiped” is hollow, and it is lighter. The pressure of gases expands its walls, and they fit snugly to the bore.


Despite the unusual nature of this weapon, it is convenient to hold it in your hands ... Although it would probably be possible to add a front handle for convenience.


Cooling on the principle of "Lewis"


The barrel itself may have a different design. The simplest can be ... a primitive steel bar with fins for cooling outside, in which a channel of the desired shape is made by the EDM method. In addition, it has two holes that serve to cool the barrel from the inside. That is, everything works the same as in the Lewis machine gun. When fired, the powder gases fill the muzzle-flame arrester, a vacuum develops in it, which draws air through the barrel. In principle, it may be thin-walled, repeating the profile of the bullet channel existing in it, but it would be best for process engineers to think about this.


This photo clearly shows the muzzle cut and the round holes that cool the barrel, through which cold air is pumped through intensive firing. The trunk itself has a longitudinal ribbing on the outside.


Again, we immediately make a reservation that the “sample” shown here is just a mock-up, just like the mock of a completely hypothetical patron. All this is done in the "plastic", because in this way it is much easier to imagine than to look at the drawings and diagrams. The main thing is to determine precisely whether the bullet of such a device or the like will rotate in flight, hit the target at acceptable distances with acceptable accuracy, and prove to be more effective than the existing bullets of a traditional design. And if it does, then why wouldn’t she come into the world, and with it, and something like this, a submachine gun?


A big disadvantage of modern models of small arms are the shops protruding from below, due to which the shooters have to rise very much above the ground, being substituted for bullets. In this sample, due to the fact that the shop is located on top of it, you can shoot it close to the ground.


As for flaws, they also have this sample, and they are visible, as they say, with the naked eye. Powerful cartridge - a large length of the receiver and, accordingly, a large total length, because the trunk of this PP must also be long in order to properly disperse its high-speed bullet. Because of its shape, the muffler will most likely not be able to be put on the barrel, moreover, the length of the weapon with it will be quite transcendent. Although it is clear that such a powerful weapon cannot have a short length by definition.

To be continued ...

        Well, why doesn’t it? A very beautiful apparatus will turn out for shooting at short distances at unarmed people. One bullet - one corpse, which could not be hit because of monstrous wounds with blood loss and pain shock. I am sure that our policemen will even like it during dispersal of rallies such as in Shies or somewhere else. The discontent of the people is growing in power, and here is such a megablaster.

            Large-caliber even in PTR did not extrude so much. And 5,56 is so much, these, here, 1500 m / s, were made in the prodigy of production in South Africa. I, about 15 years ago, read an article about that. The rifling was quickly polished to zero, but it worked very efficiently on purpose.

              Czechoslovakian small-caliber shots were designed for 300 rounds. And the bullet speed at a barrel of 150+ calibers was only 1200-1300 m / s (and if gunpowder were optimized?) ..

    1. How to obturate the H-bullet in the bore?
    2. Too large friction surfaces of a bullet on a barrel even without stabilizers.
    3. The flow around will not be so laminar that the score. the coefficient will be terrifying: the bullet will fall after a few tens of meters.
    The protrusions in the chamber straighten its stabilizers, they slide along their curved surfaces and fall into the side vertical channels of the letter “H”.

    Constant cliffs of stabilizers during opening (jamming of weapons), and those that have not come off, will go out of the barrel somewhat curved, hence the unimaginable dispersion.

    Well, not TRIZ - these are ready-made solutions obtained from the analysis of a large number of inventions, but ARIZ - an algorithm for solving inventive problems. I once took a training course on them with a margin from production.

    As I already wrote on the forum, in the article by Ph.D. Yu. Vedernikova and Ph.D. Yu. Khudyakova "A star speaks with a star" (J. "Science and Life", No. 11, 1985) star-shaped arrowheads are considered, and also the characteristics of various spatial penetrators obtained experimentally are considered.
    The most optimal characteristics of two-beam (plate) and three-beam intruders. For example, at a speed of 1000 m / s, spatial penetrators have a greater penetration depth than axisymmetric ones of equal area — by 10% for an aluminum target and 2,4 times for a ground. In aluminum plates, at a speed of 2000 m / s, a four-beam penetrator with such a beam range that determines a compromise between strength and breakdown ability, holes were formed, four times larger in area than axisymmetric. The discovered features, most likely, are explained by the interaction of elastoplastic waves that arise in the medium to be penetrated between the penetrator rays. The work of academician G.G. Black and corresponding member of the USSR Academy of Sciences V.G. Dulov and others made it possible to conclude: star-shaped pyramids with sharp edges at hypersonic flow velocities experience at least half the aerodynamic drag than an equal volume cone of the same length.

    It is interesting .. there is a place to delve into the theory, but it is futile in practice .. Both external and internal ballistics are unclear, the low operational reliability of the system, together with the high cost of both weapons and ammunition, will put a bold cross on the possibilities of its use.

    The only thing that is doubtful is penetration. If the goal is some kind of protection, and this is not necessarily a bronik, with such a pool, winter clothes in the form of some kind of zipun thread would not be any cooler - even though the stabilizers are behind the bullet point, they also need to pass - see for yourself, this is like a simultaneous strike three hefty kitchen knives. DO NOT CUT. here the bullet will be cut, not punched.

    ... only two Russian peasants, standing at the door of the tavern opposite the hotel, made some comments, which, incidentally, were more related to the carriage than to the one sitting in it. "You see," one said to the other, "what a wheel! What do you think that wheel will reach, if it happens, to Moscow or not?" - "It will get there," answered another. "And I think it won't get to Kazan?" - "It won't get to Kazan," answered another. This is how the conversation ended ...... And I will not argue how far the H-shaped bullet will fly ... nowhere, of course, it will not fly away! Take, for example, the well-known and familiar "cylindrical-conical" bullets for a long time ... How many of them have been improved, improved and will be improved at all times? A lot! But only a few samples reach production, and even less gain "appreciation". And among the rejected, not all bullets are fools or there are no improved characteristics! The reason is, "it's not worth the candle!" That is, if the new bullet is better than the one that has been produced in large quantities for many years, but the greater complexity in production and a higher price block its "life path". An H-shaped "bullet" is a rather complex construct, it will cost more than a "classic" bullet, for production you need to build a new plant ... and all this in exchange for dubious promises of "unusual" properties !? I understand that the passion for weapons is akin to love; and in love there are enough entertainers and ventures (!): there are handcuffs ... whips, latex, "role-playing games" .... But some tovarischi-gunsmiths believe that the "classical" cylindrical shape of bullets has not "outlived" itself! There is still potential for development! Well, what about weapon "fantasies", you can give examples ...

    PP project S.Sagakova chambered for the puck. Modern submachine guns create a standard caliber ammunition to 9-mm. But why not make the PP under the cartridge washer? In the bottom of the cartridge case, the primer is sealed, and in the center is placed a charge of gunpowder and a wad covering the ring bullet from all sides ... When fired, a bullet and wad fly out of the barrel, the latter quickly loses speed because of strong resistance and only the bullet flies to the target having a small cross-sectional area. Such ammunition can be placed one by one in a tubular barrel store, similar to the one offered by American W. Hunt in 1948. Application instead of traditional ammunition, ammunition with a ring bullet while maintaining its mass will lead to a decrease in the length of the cartridges by about two times, increasing the caliber will shorten the barrel without reducing the kinetic energy of the bullet. Such a cartridge will reduce the stroke of the bolt, which will increase its speed and reduce the shaking of the weapon when firing. Based on the Russian PP-90, by using such a cartridge, you can increase the caliber from 9-mm to 20-25-mm, and store capacity in 4-5 times.. Well, there are other ideas ...

      Here, just about the "inflatable bullet" ... A light pistol bullet with a plastic core, very high-speed, when it hits the target, the plastic inside is flattened, and the shell breaks along the inside of the cuts. It turns out such a "miracle" as in the middle of the picture. But ... this is again a decision "against naked Papuans." It is humane in the sense that it does not contain lead and the bullet does not fragment, but only expands. In this case, all kinetic energy is extinguished almost to zero inside the target at a distance from the entry point 12 "-18" inches in any projection, including through the tubular bones of the arms. Understandably, such a hit ends in a severe bone fracture with multiple fragments, which is very difficult to assemble and heal.



      This is not my photo, but I also have my own collection of "arrived" 9x19 and .45 ACPs of only solid and semi-sheathed bullets. Expansive according to our laws are prohibited.

    Due to the fact that real small arms are not used in movie pavilions, but in field conditions, cartridges are made exclusively in a cylindrical / bottle form factor, and shops have stamped / molded ribs to minimize the contact area of ​​the cartridge with the magazine and ensure the supply of cartridges in dusty and dirty conditions.

    Therefore, parallelepiped cartridges will not fly.

    The most optimal form of a high-pressure vessel (~ 1000 in the case of PP), that is, the barrel is a cylinder, therefore, the barrel in the form of the same parallelepiped will cause a multiple increase in its metal content.

    Tungsten-molybdenum bullets - pure sabotage: tungsten is really intended to increase armor penetration, but molybdenum in this case did not sew a mare's tail. At the same time, the difference in cost between a bullet with a steel hardened core and a bullet with a tungsten core will reach an order and more. It makes sense to use tungsten only in army long-barreled small arms with high-speed sub-caliber bullets to break through the army boron carbide body armor.

      Can I have proofs in the studio?


      The Japanese did not know ballistics and aerodynamics, but actively experimented in their savage understanding of things. Oh, no, the Japanese considered themselves smarter and more cultured than all the "barbarians" bordering on them, and even the Portuguese and other European merchants they called "southern barbarians".

      Proof A small part ... a chisel-style tip is clearly visible. The crescent-style tip was used in naval battles - to cut rigging ropes. There was also a signal whistling tip.

        Proof
        Not proof. And ayayayay for your carelessness.
        How various types of arrowheads look from the time of the early Bronze Age to the present I am aware of. I also know about the chisel-shaped tip. The article claims that in antiquity (or in antiquity) there were chisel-shaped tips with double counter sharpening, as in the proposed pool. That's about this option, I asked for proof. Below, especially for you, I give a more complete quote for understanding.
        Hypothetically, it may well look like a flat parallelepiped with the front part in the form of two interconnected ... "chisels", sharpened in opposite directions. Between them is a jumper to prevent airflow. Something similar was used in ancient arrowheads. Due to the difference in sharpening directions, they flew, spinning in flight.

        And further. All the tips with a large width shown in your picture, including the fork-shaped ones (and the crescent ones you mentioned), are cuts. And they were used against cavalry. For drawing horses, unprotected armor, large wounds. It is difficult to cut a tightly twisted and tarred hemp rigging with a thickness of 2-3 or more fingers, springy in the air, even with a saber, not like an arrow.

          Yes Yes Yes. I also doubt something that an arrow can kill a rope. All flat, wide and forked arrowheads are designed to fire on unprotected targets. For chain mail and armor, on the contrary, needle-shaped tips. I can’t say it, but I doubt very much that the chisel-shaped tip will cut chain mail. I knew how to work with metal in the Middle Ages, but the needle-shaped is obviously a more optimal choice.

    I just didn’t understand - what about International Conventions? If It really shoots, and shoots powerfully, it will no longer be a small arms, but some kind of "meat-packing plant" ...

        Already have. In America, produced pistol and 12 gauge. The name is forgotten. According to the device, the central fragment is connected by a fishing line with three additional ones. In the video that I saw there were problems with reloading since the cartridges use a weakened charge of gunpowder.

          However. Did not know. Well, then use them in automatic weapons. From medium to large caliber.

    The device turned out to be of course interesting, but not for mass production, suitable only for private production and procurement.

    They say that knowing the laws of aerodynamics, you can teach to fly even a sheet of crumpled paper.

    Probably the same applies to ballistics.

    But purely armor-piercing arrows were also known that did not rotate in flight.


    The arrow rotates not because of the shape of the tip (which, by the way, greatly interferes with the ballistics of the arrow), but because of the plumage of the arrow, which is glued to the shaft specifically so that the arrow rotates.

    Modern hunting arrows, or rather, the best hunting tips for arrows, make them as close as possible to the shape of a conventional rifle pool, and cutting blades open in this tip only when they meet an obstacle.

        You will be tortured to shoot them. After all, you shoot a bow with the usual "field" tips, which most of all correspond to a mechanical drop-down.

        And these that you have in the picture are the cheapest and worst of all fly. If it’s 30 meters, there may not be differences on some samples more than 10 cm, but it’s possible to miss the difference by 50 meters.

          Well, well ... you know better! And I put a "picture", for example, the bottom one, because I read an article about arrows, about arrowheads, where the author praised this arrowhead, assured that it was popular. So ... believed the "advertisement"!

            The bottom picture is generally similar yellow gizmo on a brass harpoon tip.

            Yes, they hunt fish from onions and where they are. There, the firing distance is literally several meters. Moreover, two meters flies through the air and somewhere a meter in the water. There are no shock loads.

            But if such a contraption gets into the side of a wild boar, up to 30 meters away, where bones still occur, then the steel blade from shock loading will loosen the brass tip, KMK. And I also think that this is for wooden arrows used with a wooden long classic bow.

            The block bow has completely different arrow speeds, there aluminum poles are used (from broken carbon ones you need to cut a lot of meat - so as not to swallow) and steel tips weighing 100 grains, rarely 125 grains. The speed of such an arrow in the best block bows for 100 m / s (340+ feet / sec).

    The appearance is so stunning that it makes no sense to shoot, any terrorist will scatter himself and in different directions. No, the truth is, the author has no problems with the design, the machine is beautiful and impressive. Only about the bullet ... I doubt that it will really fly where it should. But here on this occasion, colleagues have already expressed themselves quite competently.

    Question on the article itself:
    The reload handle with the shutter remains in place when firing.
    What does this mean? A typo?

    Multi-caliber bullet and special purpose submachine gun


    The title of the article somewhat confused me so that under the "multi-caliber" I assumed to see something like this self-defense .410 cartridge for the Judge revolver simultaneously loaded with bullets-discs and buckshot.

    Gunpowder gases during a shot fill a muzzle arrester, a vacuum arises in it, which draws air through the barrel.

    I'm sorry, what?
    1. DischargeЯLive is when something is discharged that has been charged. Applies to gases, the word bit is used.Еzhenie, from the word "rare".
    2. If powder gases fill up - so the pressure rises there and there is no need to talk about any rarefaction. And these very powder gases will get into the channels along the barrel. Hot. The cooling system is so-so ... Study the Lewis design more closely.

    No, even on a dummy she moves - see photo. But the text is of course a typo. The handle is motionless, the shutter moves
