Artillery. Large caliber. "Hyacinths"

45


We often use the expression “God of war”, which is completely obsolete. An expression born too long to be true to us. Just a cliche. Just words. In an age when huge intercontinental missiles are in mines, equipped with nuclear warheads, smart and deadly inevitable.



When in the thickness of the sea waters, huge killers are hiding not only ships, but also entire countries, and entire airfields on the surface, capable of single-handedly providing air support to entire armies.

When a simple infantryman is able to destroy not only enemy soldiers, but also Tanks, armored vehicles, bunkers and bunkers. When even automatic weapon perceived as an addition to powerful weapon systems. A soldier with a gun is no longer perceived as a serious force.

It would seem, how can a barrel weapon be "God" in the age of such powerful weapons? Produce per person about the same effect? Not even shots. Just by your very existence. God also does not show many miracles. This does not prevent the rest to believe. And even unbelievers somewhere in the depths of the soul to think about its existence. Search for other names, definitions for your own faith.

Artillery. Large caliber. "Hyacinths"


"Hyacinth" in any form returns a person to the understanding that artillery is really a god of war. Next to such a weapon, you understand the pride of the artillerymen and the horror of the enemies. As you already understood, today we will talk about the 152-mm self-propelled gun 2С5 "Hyacinth" and its sister - the towed gun 2А36 "Hyacinth-B".



Armament is continuously being improved. Systems appear that can strike from such distances where it is impossible to strike a counterstrike with already existing systems for technical reasons. The firing range allows the enemy to feel relatively safe.

It is clear that the presence of other types of weapons can compensate for this imbalance. However, only guns can completely neutralize the capabilities of the enemy guns. Just because the use of other weapons may be impossible for various reasons.

The understanding of this fact by the leadership of the USSR Armed Forces, as well as the strengthening of the capabilities of the artillery systems of a potential enemy, forced the Soviet designers to begin work on the creation of a long-range cannon. November 21 1968 issued an order MOP №592 on the development of a new long-range gun caliber 152-mm.

The order concerned at once three defense "monsters". The artillery unit was assigned to the legendary "Motovilikhe" - the Perm machine-building plant. The chassis for the self-propelled unit was to be developed by the Sverdlovsk Transport Engineering Plant (SZTM). Ammunition had to be developed by the V. V. Bakhirev Research and Development Machine-Building Institute (NIMI).

The main developer of ACS has become SZTM (today UZTM).

G. S. Efimov became the chief designer of the chassis.



The chief designer of the 2А37 cannon is Yu. N. Kalachnikov.



The chief designer of 152-mm ammunition - A. A. Kallistov.



According to the order of the MOP SKB Motovilikhinsky plant, both versions of the gun must be developed at once - towed and self-propelled. Moreover, both versions must have identical performance characteristics and use identical ammunition. For the rest, the designers did not make any special restrictions.

Those who follow our publications about stories Soviet artillery systems have already seen two innovations that were not in the design and manufacture of previous products.

First, the new guns were not created under the already existing and in service with ammunition. Involvement in the design of THEM meant that the ammunition for the "Hyacinth" was originally designed from scratch. The gunsmiths understood that it was not realistic to create a more or less "light" long-range self-propelled gun that shoots conventional ammunition. The range was necessary to increase it at the expense of new ammunition.

Secondly, for the first time "Motovilikha" designed not only towed, but also self-propelled systems. In all earlier systems, the algorithm was different. On the chassis installed already proven towed guns. That is, the designers were forced to "customize" these systems under the chassis. In this case, originally designed two identical tools - towed 2А36 and for installation on SAU - 2А37.

The advance projects were presented as early as September 1969. Moreover, future cars were developed in three versions at once. In the open, ballroom and tower. After a detailed consideration of all the options, the option of open location of the gun on the chassis was called the most promising.

Following the review of the 8 advance projects on June 1970, the resolution No. 427-151 was adopted, according to which it was proposed to activate the work on the ACS Giatsint. In fact, this resolution sanctioned full-scale project work.

The first two experimental ballistic installations 152-mm guns "Hyacinth" were ready in late March-early April 1971. However, subcontractors let them down - THEM. Scientists could not in time to apply for testing new cartridges. The delay in time due to their fault was six months.

But in September, the 1971 testing began. Ballistic installations had a barrel length of 7,2 meters. In the course of numerous tests, the following results were shown: the full-charge initial speed of 945 m / s and the range of 28,3 km, on the enhanced charge - 975 m / s and 31,5 km, respectively.



During the tests, a very strong pressure of the muzzle wave was observed. In this regard, it was decided to reduce the weight of the full charge from 21,8 kg to 20,7 kg and lengthen the barrel by 1000 mm by introducing a smooth nozzle.



Ballistic tests ended in March of the 1972 of the year, and 13 of April of the 1972 of the year were presented the projects of the Hyacinth in self-propelled and towed versions. Gun "Giatsint-B" adopted by the Soviet army in 1976 year.

Knowing the story of "Motovilikha", you ask yourself a natural question: was the SKB satisfied with the 2А37 gun? It is clear that the separate-cartridge loading approved "from above". It is clear that the main work was carried out in this direction. And other options?

Indeed, the designers of SKB developed another weapon - 2A43 "Hyacinth - BK". In this embodiment, the gun was with a cap grip charging. However, after the showing of the government commission, it was considered unpromising.

Carthus loader had two more experimental guns. 2A53 Hyacinth-BK and 2A53M Hyacinth-BK-1M ...

There was also "Dilemma - 2А36". 2A36M. This instrument was equipped with an additional battery, a NAP unit, a satellite receiver, an antenna unit, a self-guided gyroscopic goniometer system, a computer, and a mechanical speed sensor.

Tactical and technical characteristics of the 152-mm gun "Hyacinth-B":



Calculation persons: 8
Combat weight, kg: 9760

Loading: separate - sleeve

The main types of ammunition: high-explosive fragmentation, active-reactive, cumulative anti-tank shells

Initial OFS speed, m / s: 590-945

OFS weight, kg: 46

Vertical guidance angle, degrees: -2 ... + 57
Horizontal guidance angle, degrees: -25 ... + 25

Rate of fire, rds / min: 5-6

Maximum range, m: 28 500

Transfer time from traveling
in combat, min: 2-4

It is transported by ATT, ATS, ATS-59 tractors, KamAZ trucks.

The barrel consists of a pipe, casing, breech and muzzle brake. Muzzle brake multi-slot. Efficiency muzzle brake 53%.



The shutter is horizontal wedge, with a semiautomatic, rolling type. The alternate delivery of the projectile and the liner with the charge is produced by a hydraulically driven chain spreader. The rammer automatically returns to its original position after delivery of the projectile and cartridge case.

The hydraulic actuator of the rammer is powered by a hydropneumatic accumulator, recharged when the instrument rolls back. Thus, during the first shot, the shutter is opened and the delivery is done manually.

The recoil device consists of a hydraulic brake recoil and a hydropneumatic tensioner. When recoiling, the recoil cylinders are fixed.

The balancing mechanism is pneumatic, pushing type. Lifting and turning mechanisms sector type. Beds are box-shaped, welded.

Shooting from a gun is conducted from a pallet. The wheels of the gun are hung out. Lifting and lowering of the implement onto the pallet is carried out with the help of hydraulic jacks.

Dual wheels with pneumatic tires. Suspension torsion type.











Now back to the ACS. Let's start with the gun 2А37 "Hyacinth - C". The first experienced guns were handed over to SZTM at the end of 1972 of the year. In the serial production of ACS launched in the 1976 year.



The barrel of the 2А37 cannon consists of a monoblock pipe, a breech and a muzzle brake. The multi-caliber slit muzzle brake is screwed onto the tube. The effectiveness of the muzzle brake - 53%. The shutter is horizontal wedge with semi-automatic rolling type.

Brake recoil hydraulic groove type, pneumatic knurler. The recoil cylinders roll back along with the barrel. The length of the rollback is greatest - 950 mm, the shortest - 730 mm.

Chain ram with electric drive. Sending is made in two steps - a projectile, and then - the sleeve.









Lifting and turning mechanisms are sector type guns. The balancing mechanism is pneumatic, pushing type.

Rotating parts are a machine on the central pin, which serves to connect the machine with the chassis.

The gun has a light shield, which serves to protect the gunner and part of the mechanisms from bullets, small fragments and the action of a muzzle wave when firing. The shield is a sheet stamped construction and is fixed on the left cheek of the upper machine.

















The gun sights consist of a D726-45 mechanical sight with a PG-1M gun mount and an OP4M-91A riflescope.

Ammunition is located inside the case. Chargers serve shells and charges from the car manually.

When firing, the ACS is stabilized using a folding base plate. The transition time from traveling to combat is no more than 4 minutes.



















So let's summarize. TTH SAU 2C5 "Hyacinth-S".

Like most Soviet artillery systems, the Hyacinth has combat experience. Very little time has passed since the start of production of this tool, when the gun had to fulfill its purpose in Afghanistan. It was from there that the second name of this system, “Genocide,” came. The soldier will always find the most accurate designation of the weapon that helps him beat the enemy.



We did not find official data on the use of these tools in both versions. However, there are photographs that confirm this fact.





Used "Hyacinths" in Chechnya. Then in the events in South Ossetia. At least as part of the army, they entered the territory of this republic.

There is also information that the Ukrainian army used these guns in the civil war in the Donbas.

Anyway, after the collapse of the USSR, this system became the property of several countries at once. There are guns in Belarus, Uzbekistan, Ukraine, Ethiopia, Eritrea, Finland.

In general, this gun is currently quite comparable with the best Western models. And serve her long enough. "God of war", he is God. As long as there are wars on the planet, there will be a God of war. Such is the banal, but still true.

          In short, she had to shoot at the same, or greater range with much more powerful shells. Did not work out. Therefore, the 130-mm gun was in the army until the collapse of the USSR. And still applied in the same Syria.

    hi The high military power and efficiency of use (the self-propelled howitzer Hyacinth was nicknamed "Genocide") contributed to the fact that many enterprises in the USSR began to offer their own versions of the modification of such useful weapons. One of the options was BC index. The letter "K" denotes a cartridge type of loading. In principle, this approach was expected: the presence of a 152-mm shell of a brass shell significantly increases its cost. In addition, a number of 155-mm Hyacinths were produced, intended for export to countries using NATO-standard artillery shells.

          Do not pay attention to him. The cannons created under the pressure of Tukhachevsky, too, the elevation angle could be quite large, but this did not make them howitzers.
          With approximately equal mass of the projectile (in my opinion, about two kg of difference), the “Genocide” has 4 charges, from 18.4 to 6.4 kg of gunpowder. Msta has 9 charges, from 11 kg to 2 kg with copecks. The gunpowder, of course, is different, but it is quite possible to get an idea of ​​the available initial speeds and, accordingly, the available trajectories.

    Dear Colleagues. Looking at the clouds of gas from the muzzle brake in the air above the ground, I wondered for a long time why everyone always makes them strictly symmetrical. Usually mullers have double-sided horizontal "windows."

    Take a look. Muzzle gases pose a considerable danger to domestic workers and ammunition on the ground. But you can reduce it by tilting the side windows slightly up. At the same time, the tossing of the gun when firing at low elevation angles due to twofold forces (the force of the recoil of the barrel and the reaction of the coulter in the ground) will also decrease. So to speak:

    The accuracy of the eta symmetry is hardly connected - the muzzle starts to act when the shell has already left the barrel. It’s impossible to assume that all the constructor of guns is stupid (although it is possible))). What is it then?

        Symmetry Helps Reduce Tool Displacement

        What is the displacement of a self-propelled gun? Yes, and towed torque (blue arrows) is reduced. Because of him, the wheels of the anti-tank already prygiruyut-that’s an offset! But UTB somehow does not bother the military, perhaps because for the second shot the tank moved anyway.
        The angle of deviation up must be calculated. It can be small (7-8g.)

      the resultant of the DTC pulse is made symmetrical about the axis of the barrel channel for a reason. otherwise, you will get a very large tipping moment, because it is applied very far from the trunnion to the muzzle.
      Having directed the part of the exhaust upwards, you dynamically load the barrel by bending (when heated, the yield strength of metals decreases) as well as the lifting mechanism. Those. even if the lifting mechanism can withstand (and this requires a lot of metal) - with each shot you will bend the barrel down. Worse, this part of the impulse will begin to perform work on the withdrawal of the axis of the barrel channel, i.e. will not only be directed to the detriment, but also lost to the cause of compensation rollback.
      And finally, artillery firing is performed by variable charges. those. the moment from your “asymmetric” DTC will be variable.

        .
        .you dynamically load the barrel by bending (when heated, the yield strength of metals decreases)

        Perhaps this is the main reason, I can not appreciate. They do not like guns to bend the barrel, while always on the side of gravity)))
        ... even if the lifting mechanism can withstand (and this requires a lot of metal)

        UTB look wrong balancing mechanism.
        ... not only aimed at harm, but also lost to rollback compensation cases.

        This is an incorrectly axial component that is the same as with a symmetric DT and depends on its design.
        ...those. the moment from your “asymmetric” DTC will be variable.

        Well, so what? The main goal is to save people and ammunition on the ground from gases (and for the D-30, for some reason, the firing is circular) and not to exactly compensate for the throwing moment from the reaction of the support. And she herself is also a variable.

          Supporting reactions are not capable of performing work by definition. This is possible only if the soil is very elastic, but this is a very unpleasant case, which is typical of what you advocate by the accumulation of recoil energy by the gun-soil system.
          The “throw-up moment from the support reaction” is your fiction. In reality, there is a tipping moment from the effort of bestowal. It was he who throws the gun at small elevation angles. If you add a reverse impulse to this, you will only introduce additional energy into this oscillatory system, which will also have to be utilized.

          The main goal is to minimize the weight of the gun. Only for the sake of this, DTK is introduced - it saves on the mass of those units that are designed to utilize the energy of the rollback pulse.
          It seems you do not understand the order of magnitude of the effort. For example, the trunk mass of the D-30 is 1,2 tons. at the moment from this mass, the balancing mechanism is calculated. But the recoil (effort on the recoil brake rod) is 130 kN, i.e. 13,3 tons of force. Slightly so the order of the difference does not bother you?

            Understood nothing (s) What work? Where did you see that I’m fighting for the “accumulation of energy”?
            "Throwing moment from prop reactions"- your invention. In reality, there is a tipping moment from recoil efforts. It is he throws up gun ...

            Again superfluous bukuff ... reaction of a support - my invention? “throwing up”, “overturning” - the term does not change the essence, depending on the result of the action the first is even more accurate laughing And the moment is always the result of at least two forces - I mentioned the first, you insist on the second ...
            Slightly so the order of the difference does not bother you?

            No, the weight of the lifting mechanism will not increase noticeably, and indeed it is not the point.
            I haven’t received a convincing answer in the summary yet. The only sensible of all is your remark about the bending of the trunk, but I can’t evaluate it quantitatively.

              Here is the yummy. Recoil and rollback goes along the axis of the barrel. So it must be extinguished along the axis. There is nothing to create any more forces, which then need to be compensated for by other excess weight and loss of strength. And so there are enough problems.

                Rђ RІRѕS, prop reaction (soil) not along the axis of the trunk! We consider the gun as a whole, and not just the barrel. These two forces create a torque that, with a small VN angle (direct fire), already throws the gun up.

      God, why do you need a brake? What would slow down? But will it slow down the rollback if the jet of gases hits in the opposite direction? Still not fools.

        What is your “opposite side”?

    Hyacinth is not a gun, but a howitzer.

        Great gun! And towed is not bad. The drawback is huge - the shot is the 2 drawer. Well, the artillery officers are killed as professionals due to the lack of variety of shells and fuses.

    The obvious disadvantages are that it is too heavy and the shells are not standard.
