Mortar "Gall" will be upgraded

In the Petrel Research Institute (part of Uralvagonzavod), the Central Research Institute decided to modernize the silent Gall mortar, reports Rossiyskaya Gazeta with reference to the press service of the corporation.

"It is planned to introduce a modernized base plate, carrying equipment and other activities," one of the developers explained briefly weapons.

Help "RG": "2B25" Gall "- 82-millimeter silent mortar, made in Russia and presented in Belarus in 2011 year. The mortar mass is 13 kilograms, the rate of fire is 15 shots per minute, and the firing range is up to 1200 meters. The mortar is made in such a way that the powder gases are locked in the shank of the mine. Due to this, no flame, smoke or shock wave is created. The loudness of the Galla shot is compared to a Kalashnikov automatic rifle with a silencer. ” From the mortar you can fire in any weather and on any soil.

And here the same principle as in the MSS - all the trick in the mine itself,
as in the MSS in special cartridges - ejection piston,
locking powder gases.
Well done, that thought of a silent mortar!
Special forces such pocket artillery I think will come in handy!

How can modernization survive from an essentially ordinary pipe in the 21st century it started back in the XNUMXth century

Here are the guys using the Jihad app on the iPad (just a joke for a minute)

Although I am not an expert, I can really still upgrade and upgrade there. Maybe by weight, if only the first thing that comes to mind. New lighter materials

cool! to hear that I heard about him but did not see .. to shoot!

Eeyore received technical help if, but Eeyore no doubt he has smokeless
and the fireless action with his mobility then he’ll brainwash the landing

This thing is for sabotage, it is unnecessary for ordinary infantrymen, there will be enough conventional mortars, there the caliber is bigger and cheaper, etc.

[marinier]

Eeyore was referring to the length of mobile units.

[Archon]

So you still tell us which translator knows the word "landing"?

[I am Russian]

The 2B25 Gall is an 82-mm silent mortar created in Russia and presented in Belarus in 2011.

Upgraded: 2B25M "Obelix" ... probably

[roskot]

Voentorg Donbas is waiting. He is very needed there.

[python2a]

Good artillery for the company!

[kolkulon]

And why tell the mortar silent?

[St Petrov]

so they don’t kill in response, determining the approximate location by sound

[Homo]

Especially when you consider the range of 1200 meters.

[vladkavkaz]

Homo
Have you heard anything about fighting in the mountains? No?
If not, ask the people who fought there whether such a mortar is needed or not.

[saygon66]

- "The gases are locked in the shank of the mine ..." - So, you don't have to water the position with water, or bury yourself, there is no unmasking dust cloud.

[your1970]

as a sound technician - I can tell the accuracy of the notch for the shot-rupture was quite high in the Soviet army (old VPZK and AZK-5 complexes), I think the current ones are even more accurately detected ..

[Black Colonel]

Silence is relevant for the "get it down - quickly get it down" scheme. There are radar systems for determining the location of shots from the ballistic curve of the flight of projectiles. Therefore, this device is exclusively for DRG.

[your1970]

radars do not take all types and sizes of shells, and yes - "partisans and saboteurs, destroy the invaders"

[Terrible_L.]

how many wonderful brains around the world are busy making it easier to kill their own kind

[vladkavkaz]

Terrible_L.
Si vis pacem, para bellum (rus. “If you want peace - prepare for war”) For two thousand years, this saying has not been refuted.
And the situation in the world is not swinging by us.

[kolkulon]

Our saboteurs are the most.

[gg.na]

Interesting little thing! For DRG, then!

[Izotovp]

Still, they would have made the explosion silent

[Izotovp]

And for what minus ?

[Izotovp]

In fact, there is a joke in every joke: to make it like a silent shot, with locking gases and with a calculated zone of destruction. Against this background, the construction of the Swedish bouncing hand grenade is of interest. http://topwar.ru/15496-shvedskaya-prygayuschaya-granata-ab-hgr.html

[Severbob]

if instead of trotyl to download binary gas - it will be completely tmho

[Wedmak]

Something I did not understand the principle of action. The piston moves inside the shank under the influence of gases, and then locks them inside. And where then the craving ???? Gases do not go outside !!! All the work of the gases will go to heat the shank!
AA ... her ... understand. Got it.

[Black Colonel]

The piston abuts against the rod inside the mortar barrel. Upon reaching the piston of the extreme point in the body of the mine, the mine itself has almost all gone beyond the barrel.

[FIREMAN]

RF patent No. 2494337 of 2011 and immediately in the metal (http://allpatents.ru/patent/2494337.html), and several complicated technical problems were solved there. The weight of the propellant charge is changed during assembly before firing + ready-made striking elements. For DRG just right.

[S-cream]

I know cartridges for low-noise shooting with gas locking in the sleeve. But!!! There, the sleeve remains in place, in the weapon, and the bullet flies away. Judging by what was shown in the video, the whole mine flies away, along with the shank. This can only mean one thing - the mine flies out of the mortar, as from pneumatics, that is, the "propellant" charge pushes the piston, which repels the mine from the air in the launch tube.
Honestly, I don’t understand how it works. Compressed air in this case, it seems very insufficient to throw a mine far enough.
Plus, the piston in the shank moves against the direction of the mine, which also does not add range.

[Wedmak]

ie, the "propelling" charge pushes the piston, which repels the mine from the air in the launch tube.

Only not in the launch tube, namely in the liner.

The compressed air in this case seems to be very insufficient to throw a mine far enough.

So it works on 1200 meters. And the compression is sharp, i.e. as I understand it, when the piston locks the shank, the mine is already in flight. And it turns out that the residual momentum of the piston is compensated by the gas pressure in the front of the mine. Which already does not affect the speed of the mine. But the inertia of the mine itself begins to work.

[FIREMAN]

The sequence of operation of the shot is as follows:
- the shot is mounted on the pin of the firing device (mortar) in which the percussion mechanism is located;
- after the descent of the percussion mechanism, the initiating device installed in the piston is activated, the propellant is ignited;
- under the influence of the pressure of the products of combustion of a propellant charge shot moves along the pin of the firing device until it leaves;
- when the shot comes off the pin of the firing device, the piston sticks in the conical part of the shank;
- after leaving the shot from the pin of the firing device he makes an oriented flight along a ballistic trajectory before meeting with a target.

http://www.findpatent.ru/patent/249/2494337.html

[S-cream]

yeah, okay. Those. the mine is repelled by the piston from the pin, which is rigidly fixed in the launch tube. Then yes, then everything is clear.

[Wedmak]

the shot moves along the pin of the firing device until it leaves it;

But no. I understand that he does not push away from the pin, but moves along it as if on a guide.

[S-cream]

the piston remains stationary relative to the pin and pipe until it reaches the end of the shank.

[FIREMAN]

Here, in principle, what to take for an inertial reference system. Both S-cream and Wedmak are right:
1. Gases are pressed evenly in all directions in the charging chamber of the mine shaft - the piston rests on the pin - therefore it is stationary relative to the shaft and the mine shaft moves along it as along a guide. The principle is the same as in the cartridge with gas cut-off in the sleeve, only the sleeve (mine) flies off on the contrary (look at the device of the SP-2 cartridge inverted)
2. If you take the second, the piston is movable relative to the mine. But since the mortar abuts the stove against the ground, it is therefore conditionally stationary, and the gas pressure does the work of moving the mine along the rod and the bore (work on the movement of the mortar and earth = 0), then the first option is more correct.

[Black Colonel]

Sorry, did not get to your explanation. He stated his similar thoughts a little higher. +

[just exp]

in the case of silent cartridges, the gas blocker is in the sleeve, then in the mine, that is, if in the case of cartridges the piston with the blocker pushes the bullet, then in the case of a mine the mine is repelled by the piston from the bottom of the mortar.

[Mountain shooter]

Cool idea. Our cartridge when they did this, for the PSS pistol, the whole world was surprised. And then the mortar! And there, for sure, there will be a grenade launcher.
The range is quite diversionary. It is quite possible to get to any perimeter for half a kilometer, and "make up" the fuel and lubricants or ammunition depots, a Grad battery or a mortar. And on the aircraft parking at the airbase! Moreover, a fire raid, using the duration of the flight of the mine and the rate of fire, can be produced, collected, and already "on the move" when the last mine explodes at the enemy's location.

[your1970]

given the fact that there is no flame, it is also not likely to be visible in night vision devices / thermal imagers, i.e. potential sentinels with appliances and won't see a shot

[max91]

A good thing

If replacing the base plate with a flange from the 100th gate valve can be considered an upgrade ...

Recently I came across such a thing. Turkish Commando 60mm. Not very noisy. The range is about 1.5 km. Such is the artillery of special forces.

[traveler]

a very good thing for some kind of terrorists, on the quiet you can bombard stadiums or rock festivals. and you don’t understand where it flies from.

[Nikolaevich I]

There is a lot of information about the "Gall" on the Internet ... for example, on the "base" of "Gall" a 60 mm mortar is being developed with a firing range of up to 4,5 km (versus 1,2 km for "Gall"). there was an article about rod mortars, from this topic and the legs of the "Gall", most likely, are growing, although there may be a nuance: the rod mortar can shoot "noisy, smoky, flaming" (if the gases in the "shank" are not locked in any way); but it can also fire silently, smokeless (ideally) ... if the charge is placed in a sleeve, which will serve as a wedge blocking gases, a piston (whatever you want) at the end of the "shank." Nuance: you can make a "telescopic" shank; then the mine receives a movement impulse from the shank extending under the pressure of gases, which is "pushed" from the "bottom" of the mortar barrel. "(like a muzzle brake in MT-12 -" salt shaker "), if it is a mortar without a rod; or even without a" barrel "( in a rod mortar).

[Gunther]

And I would take this, it will come in handy in the mountains and in the city (for our "partners").
Considering the tasks facing the DRG, the projectile (mine) for the 2B25 "Gall" should be controlled, programmable (trigger with a delay, etc.) - just a mine is unprofitable in our time :-)

[Esseeso.]

The clever thing ...

[Olegmog]

Held a montage of titanium, amazing ease!
Can make mortar base plate.
I think the calculation will not be against!
