"Electrolet" and "Partizan": what Russian sensations happened at MAKS-2021


The main sensation of the MAKS-2021 air show was undoubtedly the fifth generation fighter codenamed "Checkmate". This promising single-engine aircraft has diverted all the attention of both domestic and foreign public, agitated by Rostec's clever PR campaign. "Haypanuli" everyone: who praised, and who and muddied the Russian novelty. However, the excitement around the Su-75 pulled away attention from other interesting domestic aircraft construction projects, and there was something to see.


The emigrants who fled abroad in search of a better life are very fond of broadcasting old anti-Soviet propaganda myths and modern Russophobic propaganda in order to justify their choice to others and to themselves as the only true one. One of the biggest nonsense that the author of the lines has heard is the assertion that Russia is allegedly unable to design and manufacture anything more complicated than an electric kettle. It is simply pointless to argue with those who, in their eyes, seriously assert something like that, because it is a waste of time and nerves. But, since there is a topical occasion in the form of the MAKS-2021 air show, let's see what we have with "electric kettles".

TVS-2MS "Partizan"


During the demonstration flight, this aircraft made a splash due to its unique tactical and technical characteristics. "Partizan" was able to take off literally a few meters after the start of the takeoff run, patrolled at an extremely low speed, and then safely landed on a tiny patch measuring 50 by 30 meters. How did this become possible?


It should be said that TVS-2MS is a modernized domestic version of the legendary Kukuruznik with a new name, since the rights to the An-2 name remained with the Ukrainian Antonov. This is a biplane, more precisely, a one and a half glider, but you should not exercise your wit and sneer at the archaic design. It is the structural features of the aircraft that determine its superiority over other aircraft in its class. In the Russian variation of the "Kukuruznik", a new engine has been installed, the cabin has been redesigned, and composite materials are used. Thanks to this, the flight range with a full load increased by one and a half times, fuel consumption decreased by 10% compared to the An-2, and all other characteristics improved by an average of 15-20%. Several countries have already shown interest in the upgraded TVS-2MS. But this is not what caused a lot of rave reviews at MAKS-2021.

The fact is that TVS-2MS was used as a flying laboratory within the framework of the project of unmanned transport systems, and here domestic developers were really able to surprise. Its experimental version called "Partizan" received nine engines instead of one at once, four additional electric ones on each lower wing. This is unusual technical the solution gave extraordinary results. An additional distributed electric propulsion system radically increased the active airflow of the wing and, accordingly, the lift. "Partizan" soars into the sky literally from a place, almost hangs in the sky at an ultra-low speed, which, if necessary, can grow up to 300 km / h, and is able to land on a tiny area. A helipad is already sufficient to operate the upgraded TVS-2MS. Those who can't wait to joke about the aircraft and its unusual appearance should take into account that this is just a flying laboratory, where promising ultra-short take-off and landing technologies are tested and demonstrated. The serial "Partizan" will be more compact, lighter and more elegant, as far as is applicable to a one and a half glider. And where can it be applied?


First of all, of course, at airfields with poor runways in remote regions. The plane can carry up to 8 passengers and about a ton of payload. However, its unique characteristics - the ability to take off and land on a helipad, as well as the ability to patrol at an extremely low speed - will make it useful for the Emergencies Ministry during search and rescue operations. It is possible that the military will also show interest in the "Partizan", which is directly hinted at by its name. As stated, the aircraft is being developed as part of the unmanned aircraft program, and this is very intriguing. Let's imagine that the RF Ministry of Defense will receive a TVS-2MS in the form of a reconnaissance or reconnaissance-strike UAV capable of taking off from any forest clearing. The carrying capacity of the aircraft in the manned version reaches 1 ton, and in the unmanned version it will only increase. It will be possible to hang reconnaissance equipment, anti-tank missiles and bombs on the Partizan, making it a heavy reconnaissance and strike drone, surpassing its competitors in some performance characteristics. It is possible that, thanks to the ultra-short takeoff and landing, it will find a place on the deck as a naval reconnaissance and strike UAV. Nothing will prevent you from teaching him to sit on the water, which will simplify his subsequent operation.

"Electrolet" Yak-40


And a little more about our "electric kettles". Currently, one of the trends in civil aircraft construction is its maximum "greening". For example, last year the Cessna 208B Grand Caravan with an electric engine was successfully tested abroad. At the MAKS-2021 air show, the Russian response was shown in the form of the Yak-40 liner with the world's first superconducting electric motor as part of a hybrid power plant. It would be more correct to say that the experimental laboratory is located on board the Yak-40, which is used as a demonstrator of Russian technologies. Working technologies.


In addition to the usual propulsion engines of the Soviet short-haul liner, a special propeller is installed on the nose of the aircraft, driven by an innovative electric motor powered by high-temperature superconductors with a capacity of 500 kW., And in the tail is a turboshaft gas turbine engine with an electric generator and lithium-ion batteries. What does such an unusual hybrid give? Yes, a lot. Firstly, it is possible to fly in various modes: take off and land on an electric motor, if necessary, turn on the gas turbine engine and recharge the batteries. Secondly, the use of high-temperature superconductor technology instead of conventional copper wires in an electric motor will dramatically reduce resistance and reduce the size of the power plant, which means both its weight and the total weight of the aircraft. Thanks to cooling with nitrogen in a cryostat chamber, the efficiency of a promising domestic aircraft engine grows to fantastic 99,5%, and the use of traditional aviation fuel is significantly reduced to 60-65%.


This kind of "electrolyte" is currently being developed in Russia, and all sorts of emigrants, clearly overheated in the sun, persistently tell us about electric kettles.

    The representatives of the expert community came to the conclusion that that the technological lag of Russia from the leading aerospace powers of the world is becoming more and more noticeable.
    “It is quite obvious that since 1999 the MAKS-2021 air show can be characterized as an event with the smallest international representation,” said Ruslan Pukhov, director of the Center for Analysis of Strategies and Technologies (CAST). In his opinion, the main reasons for this situation are the blocking by the West of almost all Russian exhibitions, as well as the conditions of the pandemic.
    “The MAKS-2021 air show was held in a limited format due to the situation in connection with the coronavirus infection. The restrictions weeded out a significant number of visitors, but this had little effect on the presence of representatives of the professional community. The current MAKS has become a less massive and entertaining, but more business event ", - said the editor-in-chief of the magazine" Unmanned Aviation "Denis Fedutinov.

    "Partizan" may well replace gluttonous helicopters if it takes off and lands on a runway no longer than 100m. and the Yak40 is generally a harbinger of the aviation of the future, at least for Russian aviation, for sure, today the Russian Federation has a development that allows the aircraft to fly on electric engines with superconductors, and it will be powered by hydrogen fuel cells, I am sure we will soon see a hydrogen electric MS-21, and then it really can be considered the plane of the 21st century!

    As a drone for the military and other government agencies, TVS-2MS "Partizan" is quite suitable for various missions. Azerbaijan used a whole fleet of "Corners" in Karabakh, albeit in a one-off version - they sent it and forgot it. But this is a clumsy example. There is a more suitable example - Il-96 - civil aviation does not use this beautiful and reliable aircraft precisely because of the large number of power units. And the question is not only about fuel consumption - the engines need to be serviced regularly, which is expensive. There will be two engines, not four - the plane will be snapped up.
    Therefore, with regard to the use of TVS-2MS "Partizan" in civil aviation, namely, the transportation of people by private companies, its attractiveness is highly questionable. Serving 9 (!) Engines, even if 8 of them are electric motors - that's a lot, and that's putting it mildly. 8 additional units raised the characteristics of the usual "Corn" not enough to burst into buying a more expensive product. What the enthusiasm is is not entirely clear. A new normal engine can improve performance anyway, without 8 additional ones.
    In general, I am glad that the airline is working and developing. Moreover, the final product can be very different for the better it is presented.

    that Russia is allegedly unable to design and manufacture anything more complicated than an electric kettle

    Russia in single copies can build everything. But in large quantities, even electric kettles are not capable of producing. Everything is Chinese. So if Nauka is docked to the ISS, then we will laugh at the escaped migrants. And so, as practice shows, under Putin, only the Motherland is quickly traded. Over the past 20 years, Putin has not even acquired his own "galoshes", he is wearing all the Soviet ones!

      Unfortunately, you are right again. There are countless examples of this. Recently: Uzbekistan is now the main supplier of cotton to Russia. Just recently it was announced that in the near future Uzbekistan will stop these supplies altogether and will export only finished cotton fabrics. So the textile enterprises of Russia, for example - in the same Ivanovo and Ivanovo region will come a tryndet, and the workers will go to the south .. And there are hundreds of thousands. This will be tomorrow.

      Flax production in Russia, thanks to the efforts of the President and the Government, is almost completely "sold out" with subsequent liquidation. In the Kostroma region, flax farms have not grown for a long time, all flax factories in the region were closed and "optimized" 10 years ago.

      Great planes! But!!! Wake up! These are plans ..., dreams ..., ideas for tomorrow. And no one has yet canceled the Russian proverb about pink dreams:

    The transition to the electric movement entails a problem in the form of the operation of the electric motor on the propeller. For an electric motor, this is a fan load at which the required power has a cubic dependence on the speed. Pumping power through the engine involves losses, including copper losses, i.e. heat losses also grow in the same relationship. There is a problem with heat dissipation, the dimensions grow, the magnetic properties of the magnets fall if they are on the rotor. The use of superconductivity reduces copper losses, which should result in a reduction in size. But the requirement to ensure the required torque on the shaft (quadratic dependence on the speed) is not removed, so that the energy consumption still remains high. The use of superconductors turns out to be insufficient to radically improve energy efficiency. A qualitative increase along with compactness can be achieved by abandoning the traditional approach to building the "electric motor-propeller" system, but this is already a different technological level, a new generation of electric motors. Experimental research is needed to confirm or disprove this, as the devil is in the details. So it's easy to start.

      Until 2030, the state will order at least 2 promising Baikal planes to replace the An-300 maize workers. Their total cost will be at least ₽36 billion in 2021 prices, the Ural Civil Aviation Plant told RBC.

      sorry, but in the examples you provided, there is nothing "forward-looking".

      First, as it turned out, the superconducting electric motor is a joint Russian-German development of the Russian company SuperOx CJSC (which supplies, in fact, the conductors themselves) and the German company Oswald Elektromotoren, which, in fact, develops the motor itself.

      Secondly, the first aircraft with a superconductor engine were designed by Siemens with the help of the same Oswald Elektromotoren.

      That is, in fact, the development is not ours. It is good, of course, to use promising someone else's experience, but to ascribe it to yourself is not very good.

      Well, laboratory aircraft with additional electric motors on the wings have also been encountered before.

      Therefore, the examples you presented themselves are certainly good. But you shouldn't make something unique out of them.

    In Russia, even such elementary factories as the extraction and production of iodine or, for example, vitamin C (ascorbic acid), have been lost. And, in the USSR, they learned how to get Vitamin C (or the isomer of ascorbic acid) back in the 1930s.

    Russia really needs Yaki and TVS. But manufacturing is not a toy. Nonsense, to consider prototypes, or even mock-ups, as an example of progress in the economy, against the background of the impossibility of producing even medical bandages (there are bandages, but the Soviet ones could even be washed, and with "modern" ones, catch only two-year-old fry in a pond)

    So in which city will the production of engines for these models be organized? Is it some East Hartford again? So whose country do you work for ... miners?

      What are you talking about? Russia has lost a lot, but gradually something is being revived in the backbone industries. Would it be easier for you if nothing had been brought to MAKS-2021?
      Work is underway on promising aviation technologies, there is some preliminary result. As for the engines for Maize, the American ones chose them even before the events of 2014. They will be replaced in the future, they will not go anywhere. A piston engine is not a jet engine.
      As for the bandages and brilliant green, listen, well, now we have capitalism like, set up the production yourself, the technology is not so complicated, you will hit the jackpot. We do not have the State Planning Commission, come on, show your private initiative, if you see a free market niche, why not? Become a millionaire.

        "Hurt"? Hmmm. What a completely unexpected label! Especially from you.

        And if there is no ambiguity, then you will be hysterical! ... with the speed of a sewing machine, giving out on the mountain "Success", which actually does not exist yet. This is hysteria when, trying to divert attention, they beat up opponents with their voice and the frequency of listing at least something .. And even better: blame the "enemy" for what he himself is to blame!

        And if in essence - shawarma and "production and delivery of scrambled eggs, tkemali-sauces, roll" in fact is not production. And you don't know what it is. And you don't know how to manage-work with a team of even more than 5 people. Let alone fifty. You are not familiar with these unwritten laws. Otherwise you would not say that .... It is obvious to those in the know. And why do you think that I am no longer "releasing the bandages?" Am I a beggar fool in your eyes? Xxx! But!

        Why do you think that you can only resist with a false and destructive point of view only for money? Judge by yourself?

        But the production of drugs, aircraft, weapons and competencies must be at a high level. And this level should not fall. Because behind this, under the conditions of external pressure, the country is collapsing as well as the foundation of its future ... and then even hysteria is not enough. Here it is time to produce holy water in industrial mass-scale. And drive evil spirits. Sorry for the slight exaggeration. If nothing else is taught, of course!

    The partisan is just an experimental version of the Kukuruznik, a flying laboratory for testing advanced technologies. No one is going to impose it with 9 motors on private companies, they will buy an ordinary one. The final version of Partizan, I think, will look more elegant.

    This is not entirely true. An electric kettle is not something worth carrying out R&D, it is easier to buy a production license and rivet.
    Here you try to create a technology for the production of powerful jet engines or turbines. Nobody will sell it to you. Russia has such competencies, so is it worth sticking it into teapots?

      What are you talking about?

      Here you try to create technology

      When some people talk to you like that, you are offended and ask for specific facts to be presented. I remember the times when there was no need to buy a license for teapots and electronics, they were already riveted, all warehouses were filled up. If this is not the case, then explain what kind of electronics Buran flew in automatic mode. Now explain why you need to re-create everything? And once to create, then who destroyed it and where are they now?

      Here you try to create technology

      But in order to present this, you first tell yourself what you created? It will be more honest.

      Russia has such competencies, so is it worth sticking it into teapots?

      What competencies Russia has, we will talk after July 29, when Nauka docks with the ISS.
