The project of multi-purpose transporter MGT

42
For many decades, the domestic armed forces have solved part of the transport tasks with the help of the MT-LB multipurpose armored vehicle or its modified MT-LBu armored vehicle. To date, this machine has become obsolete morally and therefore may need to be replaced. Seeing these needs of the army, defense industry enterprises regularly offer various options for a new multi-purpose vehicle for the troops. Not so long ago, another project of a similar armored vehicle, designated as MGT, was submitted.


Recall, the multipurpose armored conveyor MT-LB entered service in the mid-sixties of the last century, and remains in the army until now. Such a long-term use of this machine contributed to the successful design of the power plant and chassis, as well as the layout with the stern placement of the cargo or passenger compartment. Later, on the basis of the MT-LB machine, the MT-LBu project was created, which retained the main positive features of the basic design. The armored vehicles of the two models were used both independently, in the basic version of protected transport of one purpose or another, and as the basis for various special equipment.



For a number of reasons, the replacement of MT-LB machines is associated with certain design and technical difficulties. As a result, several projects of this kind were closed in the absence of real prospects, and the Russian industry continues to produce equipment created more than half a century ago. However, the failure of previous projects does not prevent the development of new machines designed to replace old equipment.

A new project of a multi-purpose tracked transporter is being developed by the Moscow enterprise Special Engineering Projects (SPM). This organization is engaged in various projects in the field of vehicles. Its specialists are developing both full-fledged new types of equipment and individual units suitable for use in such projects. According to available data, the project of a promising transport vehicle is based precisely on the SPM developments on the subject of power plants and transmissions.

The new project received a fairly simple designation, revealing its essence. The car was designated as MGT - “Multipurpose tracked carrier”. There are no other names in official sources. It is impossible to exclude such a scenario that the existing name will remain even after a hypothetical launch of mass production.

As the name suggests, the MGT project proposes the construction of a multi-purpose tracked vehicle capable of solving a variety of transport tasks. In addition, it can be the basis for special equipment of one kind or another. The developer calls MGT an innovative machine, because when it is created it is planned to use technologies that have not yet received wide distribution in the field of military technology. First of all, it is proposed to use a hybrid power plant and an electromechanical transmission.

In the basic transport version, the MGT machine should receive a relatively simple case, taking into account the basic requirements. Perhaps the machine in the army configuration can be equipped with an armored corps, but there is no information on this. It can be assumed that the armored hull for MGT will provide protection against small arms weapons and shell fragments.



As follows from the available data, the original power plant and transmission allowed to optimize the layout of the internal hull volumes. So, a number of large mechanical units can be replaced by compact cable routes. In this case, the power plant and various elements of the transmission should be located in the front and center parts of the hull, next to the control compartment. All feed should be given under the cargo compartment.

The frontal part of the body appearing on published MGT images is formed by several large panels. Provides for the use of an inclined upper front sheet, paired with a larger lower. On the sides of them are encouraged to mount small zygomatic parts. The lower part of the hull sides, having fastenings for running gear parts, should be placed vertically. The top is proposed to perform in the form of large nadgusenichnyh niches, increasing the available volumes. Behind the body should be covered with a vertical sheet. Provides for the use of a horizontal roof with small inclined side sections.

The MGT project proposes to use a hybrid power plant, which includes a diesel engine and a set of electrical units. In the central part of the hull, on the left side, the YMZ-536 diesel engine must be placed, coupled with the GWIT-210 alternating current generator with an XWUMX power of kW. The energy from the generator must come to the control system that controls the operation of all systems, as well as converts electrical impulses. A constant current must be supplied to the two traction motors DVIT-210 with a power of 110 kW. Traction motors are proposed to connect with drive wheels.

The generator, engines and control systems were developed by the designers of the “Special Engineering Projects”. The first copies of products GVIT-210, and DVIT-110 not so long ago were made by Sarapulsky generator plant. It is noted that the main units of the power plant and electromechanical transmission were developed and produced at Russian enterprises. Thus, the implementation of the project is not related to the procurement of imported components, which in the current situation can be considered a definite advantage.

A multi-purpose tracked carrier must be equipped with an intelligent on-board equipment complex, which includes a number of necessary systems, including controls. Control over the operation of the power plant should be carried out by controlling the power parameters of the traction motors. The absence of a traditional mechanical transmission, which has certain technical limitations, makes it possible to obtain new opportunities in the context of maneuverability. In particular, the car will be able to turn right on the spot.



The widespread use of electrical and electronic control systems in the future may provide new advantages. For example, remote controls can be integrated into the onboard control systems. In this case, the MGT machine, supplemented by a remote control panel, will be able to solve new tasks of one kind or another. A positive consequence of the use of remote control will be a sharp reduction in risks for the crew.

In its current form, the MGT project proposes to use the chassis, built on the basis of proven solutions and structures. On each board should be placed on five large-diameter support rollers. Also published images of the car with seven rollers on board. Regardless of the quantity, the road wheels must be equipped with an individual torsion bar suspension. Front and rear torsion bars are proposed to be supplemented with hydraulic shock absorbers. In front of the hull should drive wheels with zevochnym gear, in the stern - guides. Support rollers are not provided. A track with a rubber-metal joint should be used. Images of the conveyor suggest that its undercarriage should be built on the basis of details borrowed from MT-LB.

The optimized layout of the case allows you to get the maximum possible volume to accommodate the payload, including in the form of people. The front compartment of the hull must accommodate a double compartment of management, equipped with its own hatches in the roof. Directly behind the control compartment, on the side of the main engine, in the roof is the placement of a large hatch. It can be used for the installation of a particular equipment. The central and aft roofs can be used to place the hatches in one configuration or another. The machine can be equipped as one large doorway with several covers, and several small hatches. Side and stern doors for landing or loading should also be used.

The dimensions of the hull and the volume of habitable compartments allows you to place on board the MGT to 18 seats, including the driver. Available volume can also be used to place a load of equivalent dimensions and weight. To obtain new features, you can use the modified housing. For example, published an image of an ambulance, characterized by the presence of an additional superstructure in the aft hull. Such an add-on can be used in the construction of equipment for other purposes.

The shortened “pyatikatkovy” version of the MGT machine on official images is shown along with the tracked trailer. This product should have a large box body with its own chassis. The presence of characteristic drive wheels suggests that the trailer must have its own traction motors. The supply of energy to them, apparently, can be carried out by cables from the generator of the self-propelled machine. The design of the undercarriage of MGT and trailer for him is identical.



In its dimensions, a promising multi-purpose tracked carrier should not differ from the existing equipment of its class. The length of the car (probably in the "long" version) should be 7,21 m, width - 2,85 m, height - 2,235 m. The base of the chassis is 4445 mm, the track - 2,5 m. The chassis clearance is set at the level of 400 mm. The operating mass of MGT is defined in 12 t. The maximum carrying capacity of the machine itself is 4 t. It is able to tow a trailer weighing up to 6,5 t. Specific ground pressure is equal to 0,485 kgf / sq. Cm.

A hybrid power plant coupled with an electromechanical transmission should provide high mobility characteristics. With the help of two traction motors rated at 110 kW, the conveyor should accelerate onto the highway up to the speed of 65 km / h. It is possible to climb the slope of the 35 ° slope and move with a heel to 25 °.

A promising transporter, like its predecessors MT-LB and MT-LB, will be able to overcome water obstacles by swimming. A large enough sealed hull should have a good buoyancy margin. It is proposed to navigate through the water by rewinding the tracks. Separate propulsion for swimming is not offered. In order to prevent the frontal part of the body from burrowing into the water and flooding the roof, it is proposed to equip the car with a flip-up wave deflector. In the transport position, it must lie on the upper front plate.

At the moment, the project "Multi-purpose tracked carrier" from the company "SPM" is at the design stage. It is reported that experts have already completed the stage of calculations and mathematical modeling. Formed several options for the overall technical appearance of the future machine. According to the results of these works were published several three-dimensional computer images of the machine. In addition, published a demo video showing the features of the chassis in different landscapes.

According to the project developer, the new MGT transporter is fully adapted for operation in the difficult conditions of the Arctic. Perhaps the machine can be used in areas with other conditions, including in hot climates. In addition, it is noted that the promising project of MGT has no analogues of domestic development.



A promising multi-purpose machine MGT is proposed as a modern replacement for the old MT-LB and MT-LBu. As a result, it is designed to solve similar problems of all sorts. Depending on the configuration and configuration, this sample of equipment will be able to participate in a variety of operations and operations, ensuring the transport of personnel or cargo. In addition, it can be used as a self-propelled base for special equipment for one purpose or another.

Recall that in half a century of development and operation, the MT-LB transporter has managed to become the basis for several dozen types of equipment. Radio-electronic systems, artillery systems, special equipment of chemical troops or sanitary facilities, etc. were mounted on the existing crawler chassis. It was also created several versions of a light armored personnel carrier with cannon or machine gun weapons. Based on the basic military machine, some samples of civilian use were developed. The later multipurpose machine MT-LBu also became the basis for various samples. As before, on the basis of this chassis were built electronic complexes, artillery installations, transport and special machines.

The emergence of a new multi-purpose machine, built using modern components, but having maximum similarity to existing samples, can have the most noticeable impact on the further development of the fleet of equipment of the troops or paramilitary structures. In case of successful completion of the current MGT project, various customers will be able to get a good replacement for the existing MT-LB or MT-LBu. In this new machine, based on other ideas and solutions, will have certain advantages over existing ones.

However, we should not forget that at the moment the project "Multipurpose tracked conveyor" is in one of the early stages. The study of some basic questions has been completed and the overall look of the car has been formed. In addition, the first samples of basic electrical units have already been manufactured. Development of finished products and further development of the entire project should take some time. The complexity of such work, directly related to the use of new ideas and solutions, can lead to their noticeable delay.

Nevertheless, despite all the possible difficulties and difficulties, the project of MGT and the equipment built on it can be of great interest to domestic and foreign operators. Thus, the successful completion of the necessary work is quite capable of leading to the most interesting results. Whether the company will be able to bring its promising MGT project to the construction and testing of a prototype, and whether such technology will be able to interest potential buyers, time will tell. It is hoped that the “Special Engineering Projects” will continue to work and promptly notify the public about the successes achieved.

      Yes, no matter how much. We must follow the path of simplification, not the path of complication. Electric transmission on military equipment, unjustified complication. And even more so a hybrid.
      You are a tanker, familiar with wheeled and tracked vehicles firsthand. So appreciate the "charms" of the chassis. But this article and others like this do not appear on the Internet for the first time. Look at the list of sources under the article. And the army chassis will not be any different from the civilian one.

        To state in advance what is complication and what is simplification. that is, which transmission scheme is preferable, I think prematurely. An electric transmission, by definition, has more possibilities, besides, you should not forget the existing equipment has an extremely low efficiency, fuel consumption of 2 liters / km, which significantly reduces the scope of its application and, accordingly, increases the prospective cost of the entire complex. Increasing the capabilities of the electric transmission itself is able to resolve many previously unresolved issues, including reliability, efficiency, etc. We look:

          On the asphalt. Something I don’t remember that of the weapons and military equipment with electric transmissions, they have been in service for a long time: 90 self-propelled guns have been produced neither the Elephant self-propelled guns, nor the rest of the vehicles produced in the prototypes: this is the IS-6, nor the MKZT-7907 tractor
          And do we have, Chubais built a plant for the production of lithium-ion batteries?

            Not common, but one of many! Moreover, this scheme is far from the best, because it requires a very capacious energy buffer! For example, a circuit with multi-generators is more efficient, it has a number of generators from 10 pieces and they are disconnected or connected if necessary, which allows to reduce the requirements for the capacity of the energy buffer! But she is not the limit of perfection! Personally, I analyze this technology and came to the conclusion about the layout: generator (N-piece) -> kinetic buffer (N-piece) -> electric buffer (A-piece) -> motor -> propulsion device.

          If the winder in the field can be repaired with a "hammer, crowbar and some kind of mother", then this trick will not work with this device - you will need a workshop with an appropriate set of spare parts. For army equipment this is a big minus. And so, of course, the car is good (should be).

            And for the future, the hybrid allows you to unify units between ALL tracked and wheeled vehicles, Did the generator die in the tank? SPIT! he has 9 more of them! What are all 10 dead? take off the padded armored personnel carrier \ BMP \ BMD \ MRAP and unpaired! What, there is no padded equipment nearby? And no workshop? And there is no spare parts warehouse? Then borrow a few from other tanks \ BMP \ BMD \ MRAP, and go into battle! This alone is enough to switch to a hybrid. hi

        The charms are:
        1. Larger torque of the electric motor compared to the internal combustion engine, and the best throttle response will also count;
        2. Compactness. An electric motor similar to ICE power has much smaller mass-dimensional characteristics;
        3. Theoretically, when using a relatively low-power generator in combination with capacious rechargeable batteries, it is possible to get no less powerful installation than ICE, but with smaller mass-dimensional characteristics and better fuel economy.
        But there are also disadvantages:
        1. Effective cooling of power units and their control units;
        2. Qualification of maintenance and operating personnel (I specifically write this, because not everything is here - zampotechs)

          “The MGT project proposes to use a hybrid power plant, which includes a diesel engine and a set of electrical units. In the central part of the hull, on the port side, a YaMZ-536 diesel engine coupled to a 210 kW GVIT-210 alternator should be placed. Energy from the generator must be supplied to a control system that controls the operation of all systems, as well as converting electrical pulses. Direct current must be supplied to two DVIT-110 traction motors with a power of 210 kW. Traction motors are proposed to be connected to the drive wheels. "
          Here you already have an increase in weight, plus complexity, and as you yourself correctly noted: "Qualification of maintenance and operating personnel (I write this specifically, because not everything is here - zampotech)." And further. Since this is an off-road technique, there may be problems with electrical insulation. In principle, this is a small locomotive, if you do not take the chassis. Only there will be many problems. Even if you replace all the relay switching equipment with electronic, there will be a gain in weight, but not reliability.

            By weight, but will it be heavier than a box, a razdatka, a turning mechanism, and a bunch of other mechanical connections (and power losses on them) and connections? In terms of intelligence, there is an ICE, a Generator, a pair of traction electric motors and a distribution equipment block .. Well, a dozen meters of cable .. Now, in terms of reliability, all of the listed units are made in the factory and, accordingly, can have any class of protection against water ingress and EL damage \ current, quality control is also not a problem to organize, the precedents of reliable electric equipment, there are mining trucks in a wide variety of conditions, work around the clock and year-round, what do you think if the hybrid circuit were unreliable and unprofitable it would be used in such expensive cars? Yes, and electric \ loaders in logistics complexes drive in the tail and mane in the same way .. So the whole point is in the quality materials, the right engineering solutions, and of course quality control! All ! There will be much less problems, but the benefits, do not forget that each such unit is an autonomous generator station giving electricity anywhere in rather large volumes .. And this is light, warmth, comfort to the maintenance staff, which will be valued no less than the reliability and simplicity of the old motorbike ..

              You can also get all this from the Premier League, but for some reason it is not used.
              In 1980, at the construction of a hydroelectric power station, immediately three out of four power cars began, and then they attracted everything that could generate electricity: cranes, mobile power stations, just not to freeze the construction site, but for some reason there were no DET bulldozers there. They stood, although every kilowatt counted.

                In fact, 30-40 years have passed since that time and the technologies did not stand still, the electronics Duc stepped forward by orders of magnitude, and electrical engineering did not lag far behind, today all the delicate places of past technologies are completely solvable so you don’t have to refer to the affairs of days gone by “Ferdinad”, remember as an example, there were difficulties not with the generation of electric energy, but with its switching and transformation into the desired form, it was here that there were the most jambs and malfunctions, now this is absolutely not a problem.

            imported factories have been operating at factories for a long time, old people shy away from it like hell from incense, it’s easier for them the old Soviet one, where there are a lot of relays, etc., Ipontsi also have relays, but what’s characteristic is mostly broken mechanics - wear so to speak, and electronics - including motors and drives, you can say it’s not breaking at all. Electronics is protected by all kinds of software protections, even when you can’t work at all, it allows, but it complains a lot laughing .
            Our Soviet machines — they just stop — there wasn’t such advanced electronics in those years.
            This is what I need - modern drives and electric motors are very compact, Powerful and undemanding, you would see in which shit “gentle” Japanese-Chinese motors work, you would immediately respect the electric drive, especially ours use motors without rare earth magnets, such a fashion now, cheap and angrily, nothing to break and demagnetize. wink

              I perfectly respect the electric drive, where it is really needed, but to use it in mass military equipment is expensive and unreliable. Wedge and vibration will destroy any connection. Moreover, it is an off-road tractor. Moreover, from scratch, only two engines take a load from us: a direct current motor or a steam engine. The remaining engines need initial idle acceleration. That's what the transmission is for.

                1) the development of electrical components and electronic circuits, especially transistors - all problems with the conversion have disappeared
                2) the creation of new types of windings and automated complexes for their creation - no "manual winding"
                3) minimizing friction surfaces
                You repeat the phrases about cost and reliability that were relevant decades ago, but today these problems are no longer relevant.
                In fact, today when using the "generator-motor" scheme, we get the opportunity to save fuel during operation with frequent small accelerations and braking. But when the speed change exceeds "N", it is necessary to use the generator at not optimal operating conditions, which reduces the fuel efficiency of the system. Actually, because at the moment the most efficient scheme of the electric propulsion system is the “many generators-buffer-motor” system where the buffer acts as the adder of the generated energy, and the generators work only in one most optimal mode.

                  Energy recovery has been used for a long time, but only where you write, on railway locomotives, on passenger hybrids, in general, on wheeled vehicles. On tracked vehicles this cannot be used. There, the transmission is constantly under load.

                    No! It's not about recovery; what is recovery without a buffer buffer? stupidity do not freeze. bully It is simply a matter of the most optimal mode of operation of the generator (the most optimal efficiency on "N" fuel). And here it’s jamb after jamb for all fans of electric transmissions. In almost all projects, it is proposed to use generators based on engines that optimize shaft rotation rather than fuel consumption. For example, an internal combustion engine has a loss of energy due to idling of pistons, while a gas turbine engine generates this energy outward. But for some reason everyone is offering them specifically for generating electricity.

                . Wedge and vibration will destroy any connection. Moreover, it is an off-road tractor. Moreover, from scratch, only two engines take a load from us: a direct current motor or a steam engine.

                This is not so, valve motors take the load even better from scratch - there are no brushes, there is nothing to burn. For example, a kilowatt brush motor is about 25 cm in diameter and 80 cm in length, 40 kg. Also brushless -15 cm in length, 15 cm in diameter, weight 5 kg, I didn’t take it from the ceiling. The first isoflex is 87 years old, the second is fan 15 years, the first time we remove and clean it once a year, change brushes, pump the collector and periodically leave the collector, burn the collector. The second one on our machines is presented in 3 generations, less and less, the first one from 95 years ago, not a single one has burned down.
                And here we use the inductor type, it is without magnets. Instead of magnets, windings are added and through them the rotor is magnetized synchronously, a synchronous servo motor is obtained, it is not afraid of anything. Its direct relative is a synchronous brushless generator, we are familiar with portable gas generators, the whole structure is a stator, a rotor coil with a diode and a capacitor wink , absolutely indestructible thing.

    There was an idea to write an article with verbal exertions of the author. The name of the type is "The art of grinding water by reciprocating hand movements in a conical vessel."
    The author almost daily pleases the reader with complex logical constructions in.
    And today's article has not fooled expectations.
    "For several reasons, the replacement of MT-LB machines is associated with certain design and technical difficulties. As a result, several projects of this kind were closed due to the lack of real prospects, and Russian industry continues to produce equipment that was created more than half a century ago."
    Obviously, it should be understood that in the “motolig” there are such design and technological solutions, the secret of which has been lost and cannot be repeated, let alone surpassing their current generations.
    “The MGT project proposes to use a hybrid power plant, which includes a diesel engine and a set of electrical units. In the central part of the hull, on the port side, a YaMZ-536 diesel engine should be placed, coupled to an alternator GVIT-210 power of 210 kW. Energy from the generator must be supplied to a control system that controls the operation of all systems, as well as converts electrical impulses. D.C must be supplied to two traction motors DVIT-110 power of 210 kW. Traction motors are proposed to be connected to the drive wheels "
    Obviously, the engine power is still 110 kW.
    Such a power plant scheme is called electromechanical, not hybrid, since it lacks an intermediate energy storage (usually a battery). Or is he, but the author forgot about him?
    What is understood by the author as the conversion of electrical impulses is unknown. Either this is a measurement system of some parameters, or the author called the rectifier - a device for converting alternating current into direct current. Otherwise, where do we get direct current?
    Or am I finding fault and the article is informative and interesting?

    For Amur: Elephant and IS-6 - technology of the 30s with the appropriate performance, and in the Strategic Missile Forces the MAZ-7912 (14x12 - Topol chassis) and the MZKT-79221 (16x16 - Topol-M and Yars) are fully operated - both with electric transmission , and the Belgians in the 80s washed down an armored personnel carrier with it I don’t remember the brand

      But these technologies are still used, but only in quarry and construction equipment, and with new developments. Something after the IS-6 created the DET 250, but this transmission did not go into the army.
      “The fundamental difference between the MZKT-79221 chassis and its predecessors is quite significant. An automobile engine YaMZ-847.10 is used here (resource before overhaul - 5000 hours, oil consumption for waste - not more than 0,3% of fuel consumption) instead of a tank (resource before overhaul - 300 hours, total life - 1500 hours). The machine has changed the ideology of building a motor-transmission compartment. A new reinforced hydromechanical transmission (GMF) of its own design. Brand new axle gearboxes have also been developed and are being used, which are transfer boxes. "
      Well, where is the electric transmission here? http://www.russianarms.ru/forum/index.php?topic=1

        For Platform-O it’s normal, for heavy versions of the motor wheel, for a lighter motor axis, it allows you to get rid of extended shafts and a lot of handouts. But for the caterpillar nafig, the top linker is replaced by the DT-3PB, and the two-DT-BTR based on the DT-10. The people put their eyes on the moto league because of cheapness, but the DT-3PB has two times less ground pressure, the layout is much more convenient, with normal hydromechanical transmission, the rubber-cord track. For me, the subject is complete nonsense.

    the proposed design is unreasonably complicated. There is a desire to get money for the introduction of innovations, but there is no word about user convenience and cost-effectiveness.
    .
    Firstly. The ratio of payload and weight of 1 to 3-4 completely kills all efficiency. No electrical transmissions compensate for this.
    .
    Secondly, the layout of the hull does not allow to create comfortable working conditions and transportation of goods.
    .
    It is necessary:
    1. A simple diesel floating tractor with two engines of different power. In addition to reliability, this scheme will allow varying power without loss of efficiency and will be close to a hybrid in efficiency.
    Necessarily a low-power engine for parking.
    2. floating body in the form of a trough, as simple and cheap as possible, without doors and windows. For loading and unloading, equip with a manipulator such as a timber carrier.
    3. The driver’s cab is a truck cab type with good visibility, ventilation, heating, a sleeping bag. Set above the trough. In case of war, you can remove it, or lower it to the bottom of the trough.
    4. Automatic transmission and remote control via bluetooth or cable.
    5. A line of similar machines in size and equipment: large-medium-small and conveyor-shift-tractor.
    .
    According to my estimates, a machine the size of an MLTB can have a weight of 4-5 tons and a load capacity of 8-10 tons. Two engines: 100 and 140 hp, located between the tracks. Service diesel generator in 10 hp Mechanical transmission with hydraulic cylinders. The cabin is installed above the edge of the pelvis. Hand of a hydraulic manipulator ...
