Specialists from TsNIITOCHMASH have increased the armor penetration of tank shells

A new device has been created in Russia to significantly increase the armor penetration of artillery shells. tank and anti-tank guns. The invention was patented by the Central Scientific Research Institute of Precision Engineering (TsNIItochmash). The press service of the institute reports.

TsNIITOCHMASH noted that although the development belongs to the field of artillery equipment, it can also be used for small arms ammunition weapons... The invention was the result of the joint work of specialists from TsNIITOCHMASH and Tula State University.

By its design, an armor-piercing sub-caliber projectile is a long core, clothed in a leading device, which allows it to move inside the gun barrel. As the press service of the institute explained, a new design of the "leading device" of the feathered armor-piercing subcaliber projectile was used in the development.

The new design will increase the relative elongation of the active part of the armor-piercing sub-caliber projectile while ensuring its resistance to deformation (bending stiffness). Thus, the armor-piercing effect of the projectile increases

- said the head of the department for the development of small arms ammunition TsNIItochmash Alexei Shchekin, without going into the details of the new development.

The institute said that according to the calculations of the designers, the new device will not increase the cost of the shells.

It seems to be a trifle, but nice.

[Berber]

The very fact of work of TsNIITOCHMASH is pleasant.

And how this fact will be "pleasant" in the USA and NATO countries, I am even afraid to imagine.
We need more good news from Russia, but not only from the military-industrial complex.

Today, for example, it was reported that we will have a greater grain harvest than last year.
Also good news, and it is visible not only for us, tk. our "partners" have equated our grains with food weapons. A trifle, but nice.

[novel66]

well, "abrams" wait!

[Ka-52]

well, "abrams" wait!

Abrams is already "good" from a training blank that flew into his side at the training ground

[novel66]

it is necessary to find out more precisely about this blank, maybe to adopt it?

[John22]

The description, of course, does not explain anything, but God forbid it will pierce Abrams' uranium armor.

[Lopatov]

?
From the description it follows that the scrap has become longer, which increases the penetration

[novel66]

and how will it fit into the automatic loader?

[Lopatov]

I have no idea

[Viktor Sergeev]

And where is it written that this will lead to an increase in the size of the projectile? Weight makes sense and lies in increasing armor penetration with the same dimensions. It is said: an increase in the active part of the projectile, and not everything.

[Lopatov]

Quote: Victor Sergeev

Why "shell"?
As far as I understand from what has been written, they increase the "scrap", that is, the penetrator itself.

[Zefr]

Why not divide the crowbar into two parts, and in the barrel, when fired, the rear part is connected to the front part - there is enough effort to imprint them tightly through the spike shank, and here's the lengthening.
PS: I'm just kidding. And then everyone explodes along with the sofas

There will be problems with accuracy.
It is easier to launch a rocket through the barrel, accelerating a long penetrator. Hypersonic and controlled, at least during the acceleration phase. In order not to suffer with super-speed control.

Those AZs that are now being installed when upgrading tanks, and on new ones, allow loading a projectile up to 740 mm long. In the new projectile, as I understand it, the washer itself, which holds the scrap, of a new design, will possibly reduce barrel wear. And the ribs of rigidity were probably added to the scrap (and how else to increase its strength at a break?).

[Bad_gr]

The scrap is not as simple as I thought. Here's an example:
3VBM-7 round, 3BM-15 active part, 3BM-16 projectile (1972)

[Borets]

As I understand it, they transferred part of the charge to the master device, which made it possible to increase the length of the scrap inside the sleeve without increasing the total length.

[Bad_gr]

Quote: Borets

part of the charge was moved to the master, which made it possible to increase the length of the scrap inside the sleeve

Part of the charge was previously located in this way (around the scrap), and you cannot shove a projectile inside the sleeve, since it is loaded separately.
PS
We had a tank shell that was assembled from two parts before firing, but for a sub-caliber one this number will not work.

[Svetlana]

Nope .. that's the invention, that it did not become longer.

[Zaurbek]

Most likely, they used a pallet of a new design or material.

[John22]

"will increase the relative elongation of the active part of the armor-piercing sub-caliber projectile while ensuring its resistance to deformation (bending stiffness)" - the bushing (?) will be worn for scrap from deformation and the elongation due to what ?.

[svp67]

In this news, I was most interested in this:

The institute said that according to the calculations of the designers, the new device will not increase the cost of the shells.

Somehow it is in doubt

[123456789]

A polymer coating (such as PET Teflon) will reduce the friction coefficient by an order of magnitude and, accordingly, increase the initial velocity of the projectile, and therefore the armor penetration of the BOPS

[voyaka uh]

Right. Crowbar guides ("reels with a pencil inside") are made of polymers.

[Viktor Sergeev]

Not too much. Rather, armor penetration increases as a result of an increase in projectile weight. What you described most likely affects the durability of the barrel. By the way, a special treatment of the barrel was carried out on the new gun for the Armata.

[Split]

Well, God forbid ... because all our leads and manga are too lagging behind, that like in the Patriotic War you need to hit the side and act tactically. I think that this would have saved the old tanks, which are used in the eastern theater of operations. But what can I say, 64 became the Armata of its time, reaching the 90th breakthrough ... But the potential is, IMHO, exhausted. Many people say that the transition to 152mm will give potential, I'm not sure. Now not Patriotic, where a 152mm land mine tore the towers. I think it's all vkur about what they went to to moderate the recoil of the 152ki ... and the pressure in the barrel has long been higher and, accordingly, gunpowder and technology. The fact that 152mm Armata will not be, I'm more than sure

[zwlad]

Quote: Split

Now not Patriotic, where a 152mm land mine tore the towers.

One hit of a 152 mm HE shell on the turret, which will damage or disrupt all sights and KAZ, (kmk) is enough for the tank to lose its combat effectiveness. Maybe I'm wrong.

[Split]

Right, the explosive charge 152ki is enough to demolish all the peripheral equipment, this proves the experience of both the Patriotic and what he himself saw. A tank without support ... a pile of metal ... and God forbid you to see it ... But you cannot influence sleep

[Thrifty]

The "crowbar" itself began to be seen sliding, and it lengthens when a shot comes out of the barrel of the gun, as I understand it.

[Nikolaevich I]

Niht sprechen zi deutch ..... know andestend ... read out, pzhlsta, the whole list! (Well, okay ... it's all in the bag ... in the "master" ... the master is in the barrel ... the master is separated from the penetrator after it leaves the barrel! And then sho? How is the "antics" of the penetrator further leveled in flight? How is the armor protection overcome further? That is, how, in this case, the "increased armor penetration" "materializes"? )

[Zeev zeev]

The "crowbar" was lengthened by several centimeters, increasing the weight and increasing the stabilization by the flow in flight (the shorter the projectile, the less stable it is). The loss of speed has decreased by a couple of percent, the armor penetration has increased by a corresponding amount.

Well, lengthened the "crowbar" ... increased the weight .... It's understandable! But how did you increase the stabilization of the penetrator? Explain to me in this case!

[Lexus]

But how did you increase the stabilization of the penetrator? Explain to me in this case!

We went along the path of "Rosraspilkosmos" - we signed a contract with ... ROC, and from now on workers, equipment and every batch are sprayed with "holy water".

Many comments to the "note" can be divided into 2 "categories" ...: 1. "I hear a ringing; but I do not know where he is", "Without looking at the calendar, he thumped the bells ..." Oh, yes! There is a 3rd! "I have not read the book, but since my own party said that it was bad, then I categorically condemn it! If I said that it was good, then I categorically welcome it."

[Zeev zeev]

The stick has become longer, so it is a couple of percent more stable.

[mvg]

If you believe open sources, then the armor penetration must be doubled in order to confidently defeat the Abrams SEP3 and Leopard 2 A7, as well as the Challenger 2, after modernization. T-72/80 / 90A new ammunition is not threatened. The best for today Vacuum-2, 850 homogeneous armor. It is not enough. Even for the Merkava.

[Thrifty]

mvg-so TURs will have a higher armor penetration - up to one meter.

[mvg]

TURS armor penetration will be higher - up to one meter

Only ATGM's do not fly like a crowbar at a speed of 1800 m / s and are knocked out by KAZ. Israel has all the Merkavas and Namers with KAZ. Abrams are also equipped with Trophy, soon they will be on Lepard. The Turks are equipping their М60А3 with the Soviet Drozd. China puts on the 99A2 type. Plus passive protection methods such as smoke and aerosol protection. Reflexes-M will not run now.
We are seriously lagging behind in BOPS. Lead, Mango is a development of the 60s. And Vacuum-1,2 is definitely not in the troops. Moreover, at the factory, during the crown, barely 30% of the staff worked.

[Klingon]

Well, the guys from TsNIITOCHMASH are trying to deceive physics.
only physics is a stubborn thing. It is necessary either to alter the AZ or change the caliber of the gun to a larger one, at least 130-140mm, there is no other way to effectively increase the armor penetration of the bops, but this is dancing with a tambourine around outdated crowbars with gaining some scanty couple of percentages of armor penetration

[mvg]

for a larger one, at least 130-140mm

Even not poor Germans are expensive. And there are two hundred tanks. And we have at least 2000+ not counting in storage. And the new AZ requires a turret replacement. The shells simply do not fit into the old towers. And if you put 152 mm, then this is generally the finish. There is not enough money even for the cheap modernization of the T-72 B3. There will be a situation like in a war of attrition, an Arab-Israeli one, when a hundred Merkava-2 and Chieftains stopped 800 T-54/55.

[Klingon]

Well, this is an eternal cycle, there would not be so many sawflies, there would be money, someone from the Elves said that in the budget trillions are "dead weight". so where are they ???
By the way, the Germans and the French are going to put the Rheinmetal promising 130mm cannon on their promising new machine. The French will traditionally sculpt AZ for her. And the gun is already ready by the way

[mvg]

by the way, the Germans and the French are going to put the Rheinmetal promising 130mm cannon on their promising new car

They are not so bad with the L55. And the DM44 copes well with the T-72B3 in any projection. The same as with the T-90A / S. Israel also experimented with the 140mm cannon. Until Armata goes into series, they have nothing to worry about. And I don't really believe in the joint work of the Germans with the frogs. For me, the Leo 2A7 + is quite a good car. And with whom should they fight? There are no opponents.

[Operator]

It is not clear how, but they increased wool / armor penetration by 0,1%

[DDZ57]

The distance from the patent to the finished product is enormous.
For those interested: look at RU 2717857 and evaluate the possibility of its application in 125mm RF.
The article is about nothing.

Plus sign for resourcefulness
Thus, the proposed design of the leading device allows to achieve an increase in armor penetration due to the possibility of increasing the relative lengthening of the active part of the armor-piercing subcaliber projectile and ensuring the required value of its bending stiffness, as well as due to the use of the kinetic energy of the mass of the passive part at the initial stage of armor penetration with stability on the flight path due to the use of a part of the support unit of the master device that is not separable on the path.

[L-39NG]

I here little, little rummaged in physics textbooks. With an increase in the length of the "scrap", there is an increase in aerodynamic braking of this "scrap" and, as a consequence, the loss of certain percentages of kinetic energy and, therefore, the percentage of armor penetration is lost. At close distances this is not critical, but from 0,5 km and further - the game is not worth it, etc. Aerodynamic braking is especially effective at supersonic speeds.
Well, then, the process of producing shells and the design of the automatic loader. And, good luck, if there is nowhere to put money.

With armor penetration, we have not been beautiful for a long time. Somewhere something is announced, but in reality the good old is in the troops. Hopefully, the implementation will be rushed.
