Liner MC-21 is a platform for testing advanced Russian technologies


Two years ago, the United States imposed sanctions on the supply of composite materials to Russia required for the production of the "black wing" of the MC-21 medium-range liner. The leadership of the aircraft industry promised to make their import substitution as soon as possible, and now completely domestic "black wings" have arrived at the Irkutsk plant, where a promising aircraft is being developed. Why, then, can it rightfully be considered a real technological breakthrough, which the Americans tried so hard to stop or slow down?


The MC-21 is our first medium-haul liner designed from the ground up. Its certification is expected by the end of 2021, and serial production from 2025. The reason for such a delay and constant postponements to the right was the sanctions imposed by the United States. But why are they so scared in Washington? Irkut plans to produce up to 70 aircraft a year, while Boeing produces over six hundred airliners during the same period. For the sake of objectivity, it should be admitted that our MC-21 will be able to take a very small share of the world market. Is it really necessary for the United States to get involved with such restrictive measures for the sake of preserving it, which, frankly, does not do credit to American manufacturers?

In fact, everything is much more complicated, and the stakes are higher than they seem. The key point lies in the technologies that will be run in on the MS-21.

At first, this is, of course, the PD-14 aircraft engine. It is also a completely Russian development that meets all modern environmental standards. More importantly, it should become the ancestor of a whole family of power units: its derated version can be installed on the short-haul Superjet New instead of the problematic SaM-146 of the French design, and the more powerful version of the PD-18R (R - geared) - on the Tu-214, Il- 96-300 and Il-96-400T. In addition, to replace the Ukrainian helicopter engines on the basis of the PD-14 gas generator, a turboshaft PD-12V with a thrust of 11,5 tf for heavy rotorcraft should be developed. In general, some pluses are expected, and the promising power plant will be tested on the medium-haul MS-21.

Second, the It is extremely important for the revival of the domestic aircraft industry that the use of composite materials will be tested on the liner, their share in the MC-21 reaches 35%. Wings, keel and tail elements are assembled from composites. Due to its design features, our medium-range aircraft has the widest cabin of a narrow-body aircraft in its class. Undoubtedly, this is its competitive advantage. It is not surprising that the United States, defending the interests of its national producer, went through the introduction of restrictive measures against the Russian project, banning the supply of American and Japanese composites. The process of import substitution took two whole years, but the result was worth it.

It is interesting that in a number of media outlets all this time, the point of view that one should not engage in nonsense sounded very persistently. Allegedly, the "black wings" of the MC-21 will not give any advantage, and in general this is a dead-end path, since competitors from the USA and Europe make composite wings only for their heaviest wide-body airliners, where are we going. The most curious thing is that this is where the answer lies.

Indeed, the wide-body Boeing 787 Dreamliner and the super-wide-body Airbus A350 XWB have their "black wings". Their use was the result of intense competition between American and European corporations. The aircraft giants have grappled with each other to reduce aircraft weight and fuel consumption as much as possible in order to increase the interest of air carriers by maximizing the use of composite materials. The decrease in the weight of the liners made it possible to install additional on-board equipment on it to increase the comfort of passengers' flight. In addition, modern composite materials have a greater durability resource than metal ones.


And this is where the fun begins. There are different Technology creation of composites. Airbus and Boeing have orders for large series of aircraft, and therefore began experimenting with relatively small, wide-body aircraft, relying on the so-called prepreg technology. According to this technique, each individual piece is “baked” in special autoclaves separately, and then they are assembled and re-“baked”. As a result, a certain boundary between different elements of the same part is maintained, and the overall strength is reduced. In MS-21, they went the other way. In the production of the Russian "black wing" vacuum infusion technology is used: carbon fabric is cut and laid out in layers in a special envelope, from where air is pumped out and a special polymer resin is poured. After all this is "baked" for 20 hours. On special equipment, the resulting stringers and panels are poured together with a binder, which results in a single, more durable and at the same time cheaper part than with the autoclave technology used by Airbus and Boeing.

Thus, on our medium-haul liner, the most advanced technologies are being developed, which can later be used in the production of promising wide-body aircraft in Russia. Perhaps the Americans still have something to strain. As you know, Russians harness for a long time, but then they drive quickly.

    Not, remembering the landing of a dry superjet in May 19 th at Sheremetyevo and not only there, I'd rather fly on a "watermelon".
    And then let them continue harnessing.

      Are you ready to answer the question why SSJ died?
      This is called a choice - if you want to fly an A320 / B737 in principle, it is your choice. Just be prepared to face other challenges.
      The road will be mastered by the walking one and this reserve of the MC21 is simply necessary for the future. The Russian Federation has dropped out of the list of producers for two decades and how difficult it is to restore what was lost. Skip this generation of technology - it will no longer be possible to create the next one

      Can you try the Boeing 737? smile What is also not? Then all you have to do is to harness the horse to the cart, all the same, you have forgotten how to build airplanes.

      I graduated from the Aviation Institute in 1978. By the early 1990s, my fellow students and I had become very skilled professionals. But then EBN arrived in time with the "party and government" of Chubais and Gaidar, and they literally persecuted us for ten years, leaving us without work and wages. By the early 2000s, the aviation industry was in the deepest knockout thanks to the treacherous activities of the above goblins and the greedy officials who joined them. People dispersed, scattered. Families need to be fed and just survive. Teaching now is not the same as in our time. For what we have put three in the universities, now they sculpt nickels. students pay money, universities pay them with diplomas. And that the Perm Motor Plant, which stopped in 1995, when it could fill up the aircraft industry with good PS-90A engines, is suddenly creating PD-14 - it's just a MIRACLE! Making a wing in Ulyanovsk is great !!! To spite the fascists - the Chubais. Therefore, now young specialists are learning anew, RUNNING IN. It's not just the chubo-sawing. And the fact that - you can kill a person in a second. And to give birth and raise a new one -18-20 years. It is even more difficult with specialists. It will take 20-40 years to grow them. And the generation is lost !!! We are already retired. In our work, you study yourself and teach young people all your life.

        We are already retired

        You are wrong, comrade. You should never rush to retire. Again, keep two things in mind:

        First. Our beloved President Vladimir Putin has been tirelessly, like a galley slave, at his post for twenty years! Even his wife, Lyudmila Aleksandrovna, realized several years ago that she was very tired of her husband's endless work watch and divorced him. But this is not the main thing.
        Relatively recently, at the suggestion of our 83-year-old space Seagull, laws were literally dragged through all the formal high authorities, allowing our dear and beloved VeWePe to be president until 2042. Is this not a victory? And you, our dear worker, take an example of high service to the Motherland from our president and do not retire at such an early age.

        Second. In 2018, our beloved president came up with the brilliant idea of ​​pension reform. Our enemies viciously slander that along the path of tireless reforms, the entire pension fund was plundered, and there was nothing to pay the old people with pensions. But this is a lie and slander! Therefore, it was necessary to raise the retirement age with a mighty jerk by only 5 years. If things go as well in all areas of foreign and domestic policy, then the retirement age will have to be raised to 80 years. And here your strength, experience and knowledge will be very useful, so do not rush to rest. As in that wonderful song they sang: "But it's too early for us to die, we still have ... things to do." And take care of yourself! There is also this damned virus with all its pandemic has gone wild, if they were wrong! One thing is good - you can at least blame them on all the reasons for your epoch-making and endless successes.
        Hang in there! We wish you good mood, vigor and health!

      And another detail! Like! How are you "proud Russian pats.riots" - minus them You just caused an insulting insult laughing !
      Very true and sad! In the "damned, totalitarian, backward communist cons camp - USSR" for 30 years, let's say from the 50s after the terrible destructive and murderous - the decline in the population of the Great Patriotic War .... in fact, the Soviets again created the aviation industry and TENS !! Aviation design bureau they created a system of aviation development, aircraft construction, aircraft production! And as you know, ANY SYSTEM is created sequentially, in stages, from generation to generation. And the USSR system was successfully killed, but they CANNOT create a new one!
      ... it doesn't give instant BABLO! billions, and yachts "zabugrom" That today in Russia - yours is the most important thing in life !.
      So the current Vasharasha has been using Soviet air with ambition for 30 years with a cry - "THIS IS OUR RUSSIAN", while simply selling what is for sale, what is not for sale destroys, kills the Soviet aviation heritage, Created by fathers and grandfathers for ALL peoples of the USSR.
      Everything that the current ones are "capable of" ... by the forces of the Soviet "not finished" designers for 30 !!! years of SU-57.
      ONLY! for 30 years. and that is not yet "on the wing" in the troops.

    But why were they so scared in Washington (i.e. in Boeing)?

    They, in Boeing, were frightened not by the Russian plane, but by the Bonkers Tri-Wing Jumbo Jet!
    https://www.yahoo.com/lifestyle/bonkers-tri-wing-jumbo-jet-141500229.html
    Or
    https://www.seaeronautics.com/

    The new SE200 SE Aeronautic prototype takes a revolutionary approach to all design and performance parameters of ultra-widebody aircraft. Tricuspid design with double tail and two enginesmounted in the rear, it will be able to accommodate 264 passengers, but will consume 70 percent less fuel than a jet of similar size. This ultra-efficient subsonic jet can carry over 264 passengers at Mach 0,9 with a range of 10 miles at 560+ PMPGs.
    The high lift wing design gives the SE200 short takeoff and landing capabilities (up to 70% off takeoff / landing fuel), which increases the number of smaller airports it can reach. Some of his secrets: Fuel storage will no longer occur in the wings, so the designers made them thinner and more aerodynamic. Instead, the fuel is stored in a tank at the top of the fuselage, which is part of the aircraft's unique design. SE cites its integrated monocoque design as a breakthrough in performance and safety. The company notes that aircraft manufacturers are tying together large sections called "trunks" to increase production. “This is usually where the fuselages break in a crash,” says SE. "SE will build a one-piece, rugged composite fuselage." The monocoque construction and composite materials will make the aircraft the most efficient aircraft ever built, the company claims, with a lifespan of 50 years. “We will also be able to build these aircraft less than twice as fast as an aircraft of this size is usually built,” the report said.

      Is this in order to pour kerosene on all passengers during an emergency landing? A very interesting idea! Biplanes, triplanes and other multi-planes - all of this has already passed. A beautiful picture on the site? A freak is depicted. And ugly planes, according to the classics of aviation, fly ugly. A picture for amateurs plus a marketing ploy, no more.

    It is well said "Advanced Russian", it does not mean World advanced. You can chase as much as you like, but so far the technologies do not come to self-sufficiency, there is little sense from them. There are two leading aircraft manufacturing companies in the world. Several regional manufacturers. Russia will be added to this group. China may become the third largest producer.

    For three years we were assured that we will now solve the problem with the "black wing", and everything with the liner will be great. But the problem was solved, so what? It turns out that there is a lot more foreign in the design of the liner. And, unfortunately, exactly American.
    When the aircraft was just started to be designed, 62% of foreign components were included in it. When the sanctions frenzy began, it was decided to reduce foreign ownership to 3%. It looks like they talked about three percent, and even forgot. Because in April, Deputy Prime Minister Yuri Borisov suddenly announced that hard work was to be done to reduce the foreign share to 40%. But how much more work to be done, Borisov did not say. Therefore, there is a suspicion that the delivery date of the liner will be postponed again in 2022.
    The Americans still have excellent leverage to prevent the MC-21 from entering the market. At any time, they can prohibit the use of the most important systems they have created for the MC-21 - avionics parts (Rockwell Collins), electronic tablets (Honeywell), a "glass cockpit" (UTC Aerospace Systems), a flight control system (Goodrich Corporation), electric generators (Hamilton Sundstrand) ... And on the little things.

    This is inevitable, because it is the reason for the import substitution of these systems. The launch dates may shift to the right again, but as a result the MS-21 will be 100% domestic. There is a silver lining.

      This is already well known about Ukraine. This is the support of the LPR, the DPR without actually recognizing them, by supplying weapons, ammunition, fuel, instructors, money, volunteers, distributing passports, and thereby supporting the conflict. And they say it is good for us so that Ukraine does not join NATO, and so on.
