Military Review

Not for Senka chassis

23



For nearly a decade, experts have been debating whether special wheeled chassis and tractors are being developed in the right direction. It is too early to sum up the disputes, but it makes sense to talk about some intermediate results based on the available documents.

The fleet of military vehicles (BAT) has a special look - special wheeled chassis and wheeled tractors (SKShT). It is on them that mobile ground systems and weapons and military equipment systems are installed that can decide the outcome of a military operation.

Fifth generation in the cart

Unfortunately, after the collapse of the USSR, the Kurgan Wheel Tractor Plant, which produced SKShT, ceased to exist, and MZKT (Minsk) became foreign. Due to the extreme necessity, in the 2003, the MZKT-7930 chassis was adopted for the supply of the Armed Forces of the Russian Federation, and the MZKT-2004 (as part of the complex) in the 79221-m. This technique can be attributed to the fourth generation.

At present, the Strategic Missile Forces would consider it to be good to get SKShTs from domestic plants, but Russian enterprises lack production capacities for assembling serial complete chassis and military tractors with the 16X16 wheel formula. There are no key auto components, for example, hydromechanical transmissions (GMF).

Proposals for replacing Belarusian SKShTs with Russian counterparts were periodically placed on the agenda. It was proposed to create a domestic fifth-generation chassis and tractors. In the long term, the specialists of the scientific and technical committee of automobile equipment of the Main Automobile and Armored Directorate of the Ministry of Defense of Russia (STC AT GABTU) proposed to create a sixth generation SKShT. It was planned to develop two families: highly mobile modular chassis with carrying capacity from 15 to 40 tons and highly mobile modular platforms (PMF) 50 tons and more. In the design it was intended to widely use non-traditional technical solutions, which are today called innovations. The tactical and technical requirements for the families were developed by the 21-m Research Institute of the Ministry of Defense.

Everything went on as usual, but suddenly KamAZ Inc. appeared among the performers, which had never dealt with developments of this kind. The question of the participation of the auto giant in the program arose after the arrival in the management of the enterprise of new people. In response to the appeal of the plant, specialists from 21 of the Research Institute suggested that KamAZ develop a chassis with a mechanical transmission in order to prepare a TTZ for the creation of next-generation SKShT based on search R & D results. Moreover, TTT has already been agreed and approved by the Defense Ministry of the Russian Federation. But KamAZ was not satisfied.

In 2007, the baseline data for creating SKSHTs with “innovative” solutions were developed, which were later approved by the Deputy Minister of Defense of the Russian Federation - the head of armaments of the Armed Forces of the Russian Federation. The scientific and production center “Special Mechanical Engineering” (SPC SM) of the Moscow State Technical University named after Bauman, since KamAZ did not have a scientific and technical reserve. In addition, the studies that were carried out by Bauman together with 21 NIII for several decades (according to R & D “Development - GKNO-B”, “Fireman”, “Balsam”, etc.) needed to be continued. For example, during the performance of the research, Balsam (1997 – 2003) developed and substantiated the technical appearance of the electromechanical transmission (EMT), created a full-scale mockup model with the wheel formula 12х12, automated motion control system (SAUD), all-wheel steering (ARU) on the base of the chassis MAZ-547В and the superstructure of the diesel locomotive DM62М. However, the main unsolved problem was in the control system of traction motors (TED) - in Russia nobody was engaged in this, there was no bench base for full-scale tests. Specialists SPC SM MSTU. Bauman closer than the other teams came to the decision, but the work was stopped as directed from above.

New research received the code "Platform". The grounds for it were the Resolution of the Government of the Russian Federation No. 633-24 of 23 in August of 2008 and the State Contract No. 611 of 17 in October of the same year. The principal executor is OJSC KamAZ. The state did not stint on financial security. Veterans of the military automobile service said that the allocated amount was more than sufficient. For all the R & D for the creation of BAT in the GABTU line, the funds were allocated less than those that went to the Platform research and development project. The aim of the work was to identify the main directions of creating a family of unified HFMs of the next generation (new look of transport bases with a carrying capacity of up to 80 tons) for the installation and transportation of advanced weapons and military equipment that can be manufactured by domestic industry.

The sharp edges of the "Platform"

The customer wanted, as a result, the appearance of future SKSHTs with such characteristics that are far superior to the capabilities of the current production equipment. A few numbers. MZKT-79221 gives maximum 40 kilometers per hour on the highway, in Platform Research and Development for promising chassis with a similar formula, this speed was discussed as average when driving on dirt roads, and on hard surface - no less than 60 kilometers per hour. The largest angle of climb for MZKT-79221 - 10 degrees, for promising SKShT it was tripled. A significant increase was made in other parameters: the power reserve - respectively 420 and 1200 kilometers, the resource before the first overhaul - 40 thousands and 200 thousands of kilometers, the depth of the ford overcome - 1,1 and 1,8 meters. KamAZ wanted to jump over a generation.

According to the results of preliminary studies, the main collaborator of the SPC SM MSTU. Bauman was proposed to look promising SKShT with unconventional technical solutions, including a modular layout, SAUD, EMT, I LIE, long-wheel steering wheel suspension. It was supposed to produce a prototype model with EMT with a motor-wheel scheme (as part of the motor-wheels, it was planned to use the upgraded asynchronous TED used earlier in the Balsam research and development) and test it to verify the correctness of the chosen solutions.

With proper organization of work, the heads of the research work could provide for measures to study the reality of achieving the specified parameters and, based on the findings, produce several mock-up samples and conduct comparative tests. But something prevented.

Appendix No. 1 to the 20 Decision of April 2009 of the year outlined the technical design of the mockup model with a tonnage of 40 tons (wheel formula 8х8), which was to be built and tested. The individual parameters indicated were lower than intended and even already achieved for the 8 x8 chassis. So, the greatest depth of a ford for a prototype sample is written in the document 1,3 meter (for comparison: MZKT-7930 - 1,4 m), power reserve - not less than 1000 kilometers (MZKT-7930 - 1157 km in fuel consumption). It was determined that the supporting-running module would include a motor-wheel, other options were not considered. Nevertheless, this idea was vigorously discussed and approved at several scientific and technical councils of GABTU.

Why was the “motor-wheel” scheme chosen? Designers with experience can easily prove that it is otherwise impossible to fulfill customer desires. The development of a chassis with ASU and a long stroke suspension, which allows changing the ground clearance within plus or minus 400 millimeters, is an extremely difficult technical task. No one in the world has yet succeeded in solving it on serial SKShTs for military purposes.

Long-travel suspension is needed for off-road multi-axle chassis to improve throughput: hanging the wheels while driving on rough terrain can lead to a decrease in tractive effort, deformation and even destruction of the chassis frame. The use of power distribution schemes for the wheels of the gearboxes located inside the frame entails the use of cardan shafts, and long suspension strokes lead to the work of cardan gears at unacceptable angles, which leads to breakage.

There were also significant problems of a production nature: the technology and the basis for the manufacture of GMF for wheeled BAT Russia lost. On the contrary, it was clear to the main co-executor what kind of cooperation between the manufacturers of the set of traction electrical equipment (KTEO) for the motor-wheel scheme would be involved in the Platform research and development project.

The technical appearance was determined by the use on the prototype of large-size tires model VI-178AU, created in Soviet times. The mistake of the head performer was to ignore the need to develop a new tire, although designers with many years of experience in designing SKShTs have noticed long ago that without a new tire there is no new car. The speed limits for super-high-load-carrying structures of particularly large load-carrying capacity are superimposed primarily by the characteristics of the tires used. The probability of their failure at high speeds is very high.

Constructors had to look along the way.

Especially it should be said about the choice of diesel generator set. The main collaborator of works had proposals for domestic engines both for the prototype model and for the future SKShT family. However, the management of the head executor of the R & D system imposed the conditions under which the decision on the choice of the motor is made by KamAZ. As a result, a Detroit Diesel engine with a power of 675 kilowatts (918 hp) was proposed for the prototype model without alternative. The piquancy of the situation is due to the fact that the American company Detroit Diesel is part of the concern Daimler AG, which shortly before it acquired 10 percent of KamAZ shares (later this package was increased to 15%).

It is unlikely that KamAZ had plans to localize the production of the American engine in Russia, since in Naberezhnye Chelny they knew that the US State Department even during the best times of “friendship” strictly forbade the transfer of technology and licenses to products more than 400 horsepower to the Russian Federation . It would not have helped that the new strategic partner Daimler in the European Union offered Detroit Diesel under the brand of Mercedes-Benz. In the research documents “Platform” one can find mention of other foreign engines, for example MTU R1238K40-1822. Did the leaders of the research work think that foreign companies could refuse to cooperate at any moment? How did they want to solve the problem, if the main goal of R & D was to determine the directions for creating SKShTs on the domestic industrial base and develop the TTZ for the subsequent development work? The question is rhetorical.

Today, a few years later, the results of research can not be considered positive. One of the reasons is the staff hunger of the head performer. We repeat: before the start of the implementation of the Platform R & D project at KamAZ, there were no SKShT specialists at all - the designers had to be searched and trained along the way. So, until November 2009 of the year, that is, at the very height of R & D, there was not a single electric drive specialist in the division of the chief designer for the new projects of STC OJSC KamAZ, and the level of knowledge that started to work was insufficient.

Nevertheless, credit should be given to the chief designer of the project, who made every effort to find specialized specialists at the Crane Plant and the Transport Electrical Equipment Plant (OTEC) located in Naberezhnye Chelny.

At the stage of research "Platform" there was no comprehensive expert assessments. Top managers of KamAZ, who supervised the work, determined the subcontractors on their own. Although if leading scientific research institutes and design bureaus, which have had successful experience in developing traction electric drives since the USSR, would have done so, they would have completed all the tasks, including manufacturing and research tests of sets of equipment for full-scale moving mock-ups with different schemes and design solutions. The asynchronous oil-cooled TEDs proposed for the Platform R & D project had a huge mass (more than fivefold excess of the value realized in the experimental TED relative to that specified in the technical assignment) and had a low coefficient of efficiency during start-up modes. Full-scale tests of TED (heating, long-term operation at nominal power, at different temperatures, humidity, other external factors, etc.) were not carried out due to the lack of their own bench equipment and KamAZ’s unwillingness to agree with the neighboring specialized plant (TCEO). Therefore, the reliability and effectiveness of TED was not fully appreciated.

During the execution of work, there were questions to the converters of the traction generator and electric motors, to the control system, but the problems identified were also not resolved. Young specialists at the stage of research and development did not dare to require the management to conduct repeated high-grade tests. This later had a negative effect on OCD.

The decision of the “golovnik” to apply the improper Detroit engine on the KamAZ-7950 mock-up sample largely predetermined the further course of work. It was impossible to use proven solutions for the aggregation of the specified engine with any domestic traction generator, the best in design and performance. For a diesel generator set, the type of generator that had never been used as a traction machine, either in domestic or in foreign engineering, was forcedly chosen - a valve-inductor machine with independent excitation winding. The design of the generator did not allow it to be used in certain modes of operation of the diesel engine, and insufficient power was also revealed from the test results. The noise of the inductor generator (about 100 dB) significantly exceeded the requirements for BAT. But the specialists of the co-performer company and the creators of the generator found themselves in a rigid framework, which did not allow to find acceptable solutions.

In technical form, the curb weight of the prototype was indicated equal to 20 tons. Non-traditional technical solutions involve the rejection of heavy-weight cardan, so we should expect a significant reduction in mass relative to previous generations of SKShT. In fact, this parameter in the prototype model KamAZ-7950 turned out to be twice as much - about 40 tons. In addition, for the design of the prototype, KamAZ took as a basis the frame of the six-axle MAZ-547В chassis, which means many tons of excess weight. When performing research such decisions are valid. But as the further development of the ROC showed, the alarm bell of increasing the curb weight during R & D rang in vain for KamAZ - the calculation of the mass of the mockup was not entrusted to anyone.

Top secret innovations

It is regrettable to state: in the Platform R & D, not only the accompanying but also many necessary studies that would solve a number of important technical problems were not performed. There is only one excuse for this: curtailing R & D and the destruction of military science in the 2008 – 2012 period was a widespread practice.

The results of research gave food for thought to the specialists of the main collaborator and cooperation. The prototype model still went, albeit with difficulty, which is a great achievement of the performers. But KamAZ did not allow conducting research work with the layout - the developers-ideologues of these innovations were not allowed to even get closer to the test layout, and this is another mistake.

In the course of R & D, it was necessary to create new test methods for SKShT with NTR, to study the needs of general customers of weapons and military equipment, to take into account the wishes of the head developers of weapons and military equipment. These questions were not given due attention. Studies on the selection of power from the generator to ensure the operation of the add-in units in the movement of the prototype model were not carried out, which further affected the issuance of private technical specifications to manufacturers of KTEO.

All projects of technical assignments of cooperation of the ROC were SPC SM MSTU. Bauman prepared based on the results of research "Platform". However, KamAZ, in connection with the change of cooperation, did not even discuss these TK.

Issues of protection against new types of high-precision and electromagnetic are not solved in research and development. weapons, EW, reducing visibility in the infrared and radio bands. The correctness of the technical solutions in relation to the conditions of the Arctic, a humid climate, desert and mountainous terrain has not been verified. The questions on the use of energy storage devices and on their operation were not thoroughly worked out - the tests were not carried out. In full, not studied the security of the chassis from the detonation of mines - limited to the design and manufacture of the cabin.

The managers of the “Golovnik” were obviously in a hurry, and as soon as the right moment came (after showing to the Minister of Defense Serdyukov), the preparation of a feasibility study for conducting the R & D began. As a backlog, many new and refined technical solutions were developed and prepared, but, as practice has shown, none of them in the EMT part was subsequently claimed. The suspension had to be redone, diesel engines taken from another foreign company.

And when the necessary experience came to the developers, for the third time KamAZ had to start everything from scratch and develop SKSHT with schemes different from motor-wheel. And even go back a generation ago, that is, to a mechanical transmission. What will be the final result - is still unknown.

    93 year - the destruction of the KamAZ motor plant as a result of the fire and the construction of a new one through the knee in 25 years can and should lead to the fact that the "Tatar" dissent can be slightly transformed to your own needs ?! Accordingly, development on its own base. Well this is not a Lada, all the same.

    -a little understanding in the slots, seats, bearings, distributed loads, but 30 degrees for 80 tons ??? brilliant !!!!!!!!!!!!
    immediately clear, they wouldn’t.
    - change the head of GABTU?
    - free up space for military R&D, the creation of the holding, isolated from the "tractors of Russia"? (Will Kurgan restore Chemezov?)
    - Serdyukov’s legacy will finally be taken away and created the old Soviet?

      This is not the point, but the fact that KAMAZ interests stupidly lobbied. Given the open rudeness and greed on the part of KAMAZ, that MADI, MAMI (now UM), GAZ, BAZ and a bunch of other enterprises and institutes could not develop normal motor wheels and the chassis itself with the platform in cooperation?

        this is 7-10 years ago called lobbying (brought). but one must do something.
        Then they said "help domestic producers"
        "recapitalize ..." it was necessary to lure investment and simply save from bankruptcy of KAMAZ. THANKS. INCLUDED IN PURPOSE OF R&D MONEY. MONEY.
        and after 5 years, the s-600 will not be sold to Lat America. - "the chassis is weak, they lose to the patriots" the auto industry always lagged behind and will continue to be so.
        Apparently.
        it will save the country (again, apparently-MAY) lightening the mass of missiles to the existing g / n chassis and dividing it into several chassis from one platform.

    It is very difficult to start doing something new, so do not criticize KAMAZ too strictly. In the USSR, large missile tractors were designed only on the MZKT, and the closed KZKT only engaged in their production according to documentation from Minsk. Today Minsk is a different state, moreover “multi-vector”, therefore, there is no alternative to setting up production of wheeled tractors in Russia. KAMAZ is a large machine-building enterprise with a powerful design bureau and large production capacities, although it has no experience in developing such specific equipment. The personnel problem can be quickly resolved by luring key specialists with MZKT by drastically increasing their salaries at a new job. The very idea of ​​using electric transmission in the "Platform" is very good, because the design is greatly simplified and facilitated, there is no need to use many gearboxes, which significantly reduce reliability and increase the complexity of maintenance. I have only one question on electric transmission: what is its resistance to nuclear explosion EMR and water resistance?

    Now it’s clear why in Russia there was an increased interest in purchasing MZKT! Kamaz will not be able to create something like Minsk tractors for a long time - there is no school. Plus MZKT is located in the capital of Belarus - Minsk, and it is a two-million city. There are no problems with staffing, as There are many technical universities.

    As well as there is a positive experience of cooperation with the Belarusian MZKT. The only question is what the Russian armed forces want in the end: a "raw" domestic product, or a time-tested tractor. Especially when you consider under what types of weapons these tractors go.

        God be with him, with the MZKT. Feeding troughs are lost - they can start thinking with their heads ... It works like that as a whole.
        The question is how the Tatars work, considering what they put in the okrug imported dvigun ??? This is normal?

    but let's look at this story from a slightly different angle. so there is a certain plant in Tatarstan that has never anything but the "Tatar miracle" - it’s not a camel but rides, it didn’t produce. but this plant has a host who came up with a "brilliant" idea about how to make money :) and this idea was originally aimed exclusively at (drank) making money and nothing more, because it was immediately clear that the idea of ​​a motor-wheel was nothing.
    and, of course, this idea passed through reflection in high Kremlin circles and acquired additional ideas. a scarecrow was invented about the fact that Belarus refuses to supply tractors for Russia (due to the multi-vector policy of the latter), which, however, did not prevent it from putting tractors in the floor of the world :). at the same time, an attempt was made to buy an enterprise for a cheap price so that it would most likely go bankrupt (well, that there would be nothing to compare the Tatar “miracle” with and at the same time remove competitors). Naturally, the scarecrow turned out to be just another lie. MZKT never refused to Russian representatives in the supply of its products. and it’s strange to hear about a “foreign country” when, firstly, the common economic space, secondly, the absence of borders in the third sector is 90% made of Russian components. and the remaining 10% cannot be called exclusive :). In fact, MZKT is a solid assembly plant. but someone decided to cut money, and moreover, very large ones. I am almost sure that these people were initially preparing precisely to make just a copy of the MZKT. but for a copy of a lot of money you can’t cut it down, but the development of the motor wheel sounds beautiful and large-scale (in Russian) .In general, summing up all the above, I think that in a couple of three years all new inventions will settle down and Russia will continue to calmly buy the MZKT or just as calmly and without a pump will agree to open a subsidiary in Russia under the control of the Ministry of Labor and Trade (products must be of high quality). Confirming once again the old rule that any hype is usually aimed at hiding or someone’s attempt to get rich at someone else’s expense or simply failure.

    Ohtyzh ... I thought with the "platform" everything is much more rosy.

    I don’t understand one thing, what is the logic of “horses”? Get rid of imports from Belarus by installing dvigun from the USA? Staaa? The logic of MO is understandable, but the logic of KAMAZ boldly stands on a par with our football and cinema.

    The motor wheel can be replaced by a multi-engine chassis, where the chassis consists of several sections with its own engines, electronically or mechanically controlled, or a hybrid version.

    And where to place the engine is already a secondary issue, it can be on the side, on the bottom, on the front or on the back of the section, but at least in two places, but it is not advisable on the top - there is the working space of the attached units.

    A very strange article. Technical information is almost zero, and all that is speculation and lies. The author does not own the question at all and does not know how to google. For example, "... the type of generator that was never previously used as a traction in either domestic or foreign designs was forcedly chosen - a valve-induction machine with an independent excitation winding." A generator that has not been used before has been used for many decades on airplanes, ships, and even feeds passenger cars of all long-distance trains in our country. And since the generator can be an engine, you can google it and find that for these machines developed at MPEI, the 2011 Russian Government Prize was awarded in the field of science and technology. And if we recall the Krymsk R&D, where both the generator and all the traction engines are of this type, then the joke of the author of the article about “100 dB” (correctly, by the way, dB is 9th grade physics) looks out of place. You just need to watch the video when the APC is moving in a "silent running" mode from the molecular storage device, and you can hear the birds singing, and in the background there is only a quiet buzz of gearboxes. Was it worth it to change the asynchronous, which weighed 5 times more and proposed by the Baumans, to a valve-induction machine that proved to be in the Krymsk R&D and developed at the Moscow Power Engineering Institute? Already, representatives of the divan troops about this are unlikely to have the right to reason. Arguments of the type “The issues of protection against new types of high-precision and electromagnetic weapons, electronic warfare equipment, and reduced visibility in the infrared and radio ranges are not resolved in research work.” I can’t say about all the questions, there is no data, but about the infrared range, this is again school physics. It is very difficult to make a sequential hybrid consume more fuel than its mechanical counterpart. Almost impossible. Savings from 10 to 40% due only to the operation of the internal combustion engine in a good mode for him. So if we began to burn less fuel, where did the visibility in our infrared range increase? Chatter, not an article ... Everyone can criticize, but they can’t do anything for couch troops to go!

    The decision of the “boss” to use the wrong Detroit engine on the KamAZ-7950 prototype model largely predetermined the further course of work.

    In short, the “boss” with its lobbyists initially led the matter to the big “smut” for the customer. I would suggest that the Investigative Committee deal with the question of how KAMAZ appeared in this whole story.
