On the basis of the universal tracked platform "Armata", three models of military equipment for various purposes have already been created, and new unified vehicles may appear in the future. A number of unified units and systems are used in existing and anticipated projects, incl. power point. The latter was created specifically for the Armata platform and should ensure the achievement of high technical characteristics.

Platform and its engine


The program for the development of a promising platform and armored vehicles based on it was launched in mid-2011.The main design work took several years, and already in May 2015, the first open demonstration of armored vehicles of a pilot industrial batch took place. In the same period, a long process of testing, refinement and preparation for a full-scale series began.



The basic platform "Armata" was equipped with a unified power plant built on modern units. Its parameters were selected taking into account the need to ensure high mobility characteristics of various equipment with a different layout and combat weight. Depending on the design features of the armored vehicle, the power plant can be placed in the bow or stern of the hull.

The power plant "Armata" is made on the basis of the 12N360 engine (designations A-85-3A and 2B-12-3A are also known), produced by the Chelyabinsk Tractor Plant "ChTZ-Uraltrak". Curiously, the engine is several years older than the universal platform. According to some reports, such an engine was created for the promising Object 195 tank, but this project did not progress beyond testing.

In the 12s, the development organization began to openly show the new engine at military-technical and industrial exhibitions. At that time, the direct connection of this product with the tank industry was not confirmed. 360НXNUMX was positioned as a motor for special-purpose vehicles and equipment for the oil and gas industry.

Later it became known about the use of the A-85-3A in the project of a promising armored platform. Such engines were to be used on all models of the family and provide high energy parameters - regardless of purpose, layout, combat weight, etc.

New solutions


The 12N360 engine has 12 cylinders and is built in an X-shaped scheme, which made it possible to reduce dimensions and weight. The length of the product is 900 mm with a width of 1,8 m and a height of 830 mm. Dry weight - 1,5 tons. Thus, the new engine is more compact, but heavier than previous V-shaped tank engines, such as the B-92.

The engine is a four-stroke engine and can use different types of liquid fuel. Cylinders with a total volume of approx. 35 liters have a direct injection system. Turbocharging is used in the form of two gas turbine superchargers serving half of the cylinders. The cylinder block is cooled by liquid. There is an intercooling of the charge air.

The 12N360 engine initially had variable maximum power. The first modification, depending on the mode, could produce from 800 to 1500 hp. at 1800-2100 rpm In the future, it was reported about plans to boost the engine with the achievement of 1800 hp. and keeping the turnover at the same level.

Thus, when installed on vehicles of the Armata family with a combat weight of 50 tons, the A-85-3A engine provides a specific power from 16 to 36 hp. per ton. The optimal value of this parameter is considered to be 25 hp. per ton, and the new engine retains a significant margin of performance for further upgrades.

A mechanical transmission with robotic gear shifting is interlocked with the engine. Its main unit is a central gearbox with integrated reverse. The box has 8 gears, and the reverse allows you to use them when moving forward and backward. Thus, in fact, 16 forward and reverse speeds are provided.

The engine, transmission and other units of the power plant are made in the form of a single unit, fixed in the engine compartment of the MBT or other armored vehicle. In the event of a breakdown, it is possible to remove the entire unit and install a new one. These procedures, when using a repair and recovery vehicle, take about half an hour.

Benefits of novelty


Due to the new power plant, the unified Armata platform has significant advantages over the armored vehicles of older models - both in terms of basic technical characteristics and in terms of project development and subsequent operation.

First of all, it should be recalled that the domestic armored vehicles will receive 1500 hp engines for the first time. or more. This will give an obvious increase in mobility and flotation, as well as affect overall efficiency. At the same time, power density and specific fuel consumption have improved in comparison with older diesel engines.

12Н360 is more flexible in its application. By setting the required maximum power, it will be possible to adapt it to the requirements of a specific combat or auxiliary vehicle and obtain an optimal ratio of characteristics. Accordingly, equipment of different types can be equipped with a unified engine, and not only within the framework of one platform.

At the stage of development


Over the past several years, various stages of testing of various types of equipment on the basis of the Armata platform have been going on. It is known about the existence of a number of main tanks, heavy infantry fighting vehicles and armored personnel carriers on a common chassis with a unified power plant.

According to the known data, sea trials of such equipment pass, in general, without significant difficulties. In the recent past, the Ministry of Defense has repeatedly published spectacular footage of tanks at full speed, powered by 12N360 engines and other new units. However, as far as is known, during the tests, certain features and shortcomings were identified that require correction.

In the wake of the Army-2019 forum, it was reported that a promising engine for the Armata in terms of efficiency, heat transfer, resource, etc. inferior to modern foreign models, and this does not suit the military. At that time, it was proposed to consider the possibility of using a different engine. However, in the future, there were no reports of platform remotorization.

Probably, the development of the platform and technology based on it in the proposed configuration has been successfully completed and made it possible to get rid of known shortcomings. This allows you to continue the production of armored vehicles and transfer them to the troops for the next scheduled activities.

Appearance of the future


An interesting situation takes place in the context of the power plants for the Armata platform. First, a promising engine of an unusual scheme appeared, and only then the development of a new family of equipment began. Then such a motor was modified for new needs, combined with a transmission of the required design and introduced into the unified platform units.

In the foreseeable future, equipment based on the "Armata" will be put into service and will begin to enter the troops in significant quantities. In the distant future, this platform may even become the basis of a fleet of Russian armored vehicles. Together with it, a unified power plant based on the 12N360 engine will become a key component of the army materiel. Obviously, the development of this engine will continue and lead to improved modifications or completely new products.

It is quite possible that the modern 12Н360 will eventually become the basis of a whole family - and will take the same place in stories tank building, as the legendary B-2 in the past. However, while the developers of engines and armored vehicles face more mundane tasks. It is necessary to rid the engine of the identified shortcomings and bring it to full operation, giving the army all the new advantages.

        This is the same expert! How can you do that? The shift selector will prevent you from shifting gears. Only consistently. An interesting case was with me during my work in the experimental transmission department. KB-3 of the Kirov plant. Back in the first nineties, there was a question of installing an automatic switch in the T-80. This work was carried out within the framework of the complete automation of the transmission with the GOP. At that time, we had no idea about stepping E / D, only solenoid actuators were in use. The development was entrusted to the leading designer. on hydraulic systems to Petr Petrovich Sergienko. The work did not go well, everything turned out to be very difficult. Opposite his desk sat his old friend, who was also the leader in hydraulics, but only the serial department. He brought a broken alarm clock from home and began to take it apart. P.P. looked at it and asked how the alarm clock works. When it came to the P.P. I just jumped up ... A day later, there were already outlines of an automatic switching device with two magnets and an anchor mechanism. One stroke of the magnet plus or minus one gear.

    Well, I'm certainly not a specialist, but modern foreign models are much heavier machines, it is quite logical that the "Armata" engine will be inferior in terms of power and efficiency, I may be wrong, but the efficiency of the internal combustion engine generally increases with an increase in their size, and heat loss decreases.
    I don't see any particular tragedy in this, the important thing is that the engine provides this universal platform with good speed and has the potential for modernization.

    Curiously, the engine is several years older than the universal platform. According to some reports, such an engine was created for the promising Object 195 tank, but this project did not progress beyond testing.


    These two pieces of text contradict each other. The development of the 12N360 engine began when no one had thought about the Armata yet.
    For the first time it was used even earlier than on Object 195, on Object 187 - in the first half of the 90s. or rather on

                The compression ratio is a purely geometric parameter. This is the ratio of the total volume of the cylinder to the volume of the combustion chamber. Therefore, the supercharging in the compression ratio cannot be "reflected" with the most unbridled imagination.

                        Again the fairy tales began .. What are such horrific conditions and loads? Express it not in pretty words, but in ordinary numbers! What is the load on the tank engine? What temperature does it work at? At what speed is the maximum operating time .. There are numbers for all this and much more, and looking at them you can say something, bring them! Yes, the tank carries 50 tons all the time, but it does it at an average speed of 20-30 km / h, the same tractor carries 30-40 tons at an average speed of 80-90 km / h for days and hundreds of thousands of km. in the truck? It is clear that the operating conditions are different, but in the end everything will come down to the perfection of the engine! Remove the ecological strangleholds from the truck engine to Euro-0, reduce the resource to 10 km, the service mileage to 000 km, do not limit fuel consumption, let him eat as much as necessary and the engine will give such opportunities that tank diesels can only dream of, and why, because they MODERN! They are made in order to compete with a dozen of similar ones and be at least no worse than others, otherwise no one will need them! Tank engine engineers do not have such a problem, there is zero competition, the military that put TUs are traditionally stuck in the last war, but the military does not care about the attendant problems of new technology, in the army, competition manifests itself only during wars! Then, yes, the military immediately needs the maximum possible of what is available .. That is, during wars, technical progress develops by leaps and bounds .. That is why now the volume of such a diesel engine is removed from a liter of 500l / s, (with poor all other characteristics) and with commercial 30-50l / s with millions of runs and interservice maintenance of 60 km ..

After problems with the supply of tank armies in the Great Patriotic War with diesel fuel, which was banal in sufficient quantities in Germany, they came to understand that the engine must be either multi-fuel or on the fuel of the alleged enemy. I know about the BMP-3 tests. Nevertheless, the BMP-3 was running on gasoline. Which European FUR engine will run on gasoline.

        The layout of the tank is a gem! If for an aviation star-shaped, even a multi-row one, this is the norm-uncoated-available for service and repair-to do anything from the uncomfortable side is already a feat! On a tank bottom, you can't repair it especially through the hatches!

    And the diesel is Normal, count from a clean slate,

    So the fact of the matter is that the engine is one-time. For the development of the country, a whole line of engines is needed from a liter diesel engine to huge marine diesel engines.

    Grandfather B-2 is certainly a well-deserved engine, but it is already many, many years old, and forced to the limit (no joke, squeeze 400hp from the 'base' 1130hp).
    What else do we have?
    The UTD family (V6 and V10) are lightweight for MBT, they have their own niche.
    The new YAMZ Euro-sixes of the 6th and 7th series are also not rolled for armored vehicles, after all, they are 'greenhouse' ones (common rail, ECU and other stuffing), all the same in civilian life they belong (by the way, what is not a line of cargo diesels ? Power range is just from 150 to 600hp).
    And for the tank so far only this one is the most suitable, if only they did not abandon it, otherwise they like to throw off good ideas with us halfway through, and again covet the import.
    Although, against the background of the events of recent years, like a roast rooster pecked (the same sanctions, import substitution, and te teh), things should go.
    On marine diesels, to Koloment and St. Petersburg "Zvezda", like there is stirring, albeit weak.

    The unification of diesel engines in "one line from liter to marine" is extremely vague.

    Whatever they say about the shortcomings of the new engine, they are all removable, but in the applied engine scheme the crankshaft is two times shorter !!! therefore, it is much stiffer and stronger than the usual V-shaped engine.
    The new engine has great opportunities for further upgrades and an increase in power, it can even be made in a 16-cylinder version, this will increase the engine length by only 30 cm

    The X-shaped model has only one significant drawback, characteristic of all engines with a "lying" type of cylinders (subarovody, pistons and owners of boxer motorcycles will not lie) is the increased oil consumption associated with this arrangement, as well as more wear on one side of the liners (bottom).
    But for military equipment, you can safely close your eyes to such a thing, the total resource of the engine will be exhausted faster than it will come to replacing the liners.

    I have pointed out in parentheses about the shortcomings of MODERN engines with a similar layout.
    Once again, for those who are particularly smart.
    In opposites, and just horizontal rowers, this is a Congenital sore-zhor of oil and one-sided wear of liners, ask any mechanic who has dealt with them, or at least read on the forums of owners of opposites, everyone will unanimously answer about this "feature", and do not re-image the pictures taken from the ceiling.
    Why the same MAN "Unterfluer" did not find widespread use, although they ran pretty well, just because of the characteristic problems of the "couches", the Germans themselves prochukhali, by the way.
    Enough is not the Germans to pray, honestly, tired.
    And who told you that the Germans had no problems with them?
    Did you communicate with them, read specialized literature?
    Something besides them Nobody in the world has used such technical Ugliness (inverted V-shnik), and after, and now, such idiocy is not observed.
    The Germans in general did all sorts of funny things, but this does not mean that they are geniuses by default, they had no less of their dead-end developments, if in general.
    In general, this admiration is already annoying, incl. And on Topvar.
    No, no, and yet another sofa mechanic will fit in and insert his unnecessary five cents "but the Germans! ..."
    ZY It's like one friend here rubbed me about a year ago, in the topic about the 5TD / 6TD family, that they also "had no problems" with Yumo-205, and we (Kharkovites, or rather) screwed up everything.
    Although it is enough to read the specialized literature, familiarize yourself with the history of operation, and it is immediately clear that they quite had it for themselves, and just in Kharkov, at the cost of incredible efforts, they brought, in principle, not the most successful design to acceptable (relatively) indicators.

        High-speed ones are produced by PJSC "Zvezda", this is a 7-ray star marine diesel engine for 56 cylinders, if necessary, two such engines are sometimes combined into one unit, as a result, 112 cylinders are obtained (very unreliable), but I think they will establish the production of medium-speed diesel engines with fewer cylinders.
        Regarding the inverted V-shaped, it was made to increase the pilot's view without increasing the cross-section of the fighter fuselage in the cockpit area.
        Due to the uneven wear of the cylinders in the X engine, of course, the details are unknown, but this engine has two planes of symmetry, vertical and horizontal (in the V-shaped only one vertical), therefore X-shaped engines, in principle, can be turned 180 * relative to the crankshaft axis, then the lower cylinders will be at the top, which will help extend the resource.

    As for the overturns, the Engines gave out the required parameters in terms of power and are relatively reliable and basta, and in wartime, such trifles as economy in fuel and lubricating oils are looked at last, if only it would work in battle.

    it was reported that a promising engine for "Armata" in terms of efficiency, heat transfer, resource, etc. inferior to modern foreign models, and this does not suit the military. At that time, it was proposed to consider the possibility of using a different engine.

    The best examples of domestic engine building - the YMZ family of industrial engines, have a resource of 5000-7000 hours, which is three times less than CUMMINS engines of 20000 hours before overhaul.
    With military engines - overpowered to obtain high power, the situation is many times worse than with industrial ones.
    I remember an attempt to adapt in-line engines from armored vehicles to industrial purposes (for graders, loaders, excavators), led to a complete fiasco - the resource of military "crafts" did not even reach 700 hours, which led to the refusal of conversion.
    The engine-building base in the Russian Federation is not just bad - it is miserable.
    For comparison, the PRC mastered the production and technology of engines of the series: Ricardo - Weichai Ricardo Engine (small and medium power R4-R6 series), Weichai Deutz and Weichai power (WD WP series from 2.3 liters to 65,7 liters), an unlicensed CAT series is produced 3306, joint production of Chongqing Cummins Engine Company (CCEC) heavy industrial engines and DCEC-Dongfeng Cummins Engine Company - medium industrial engines of 3-10 liters volume.
    That is, the PRC closes a very wide range of industrial diesel engines and has a choice of several manufacturers in terms of price and quality.
