Russian promising aircraft engine PD-8 is being prepared for the start of certification tests

Work on the creation of a promising aircraft engine PD-8 entered the stage of testing prototypes. Yuri Shmotin, Deputy Director General - General Designer of UEC JSC, told about this.


Three prototypes of the promising PD-8 engine have begun testing, the developers are preparing the engine for certification and engineering tests, which will begin this year and continue next year. Now the issue of creating a new engine for the Mi-8 helicopter based on the PD-26 gas generator is being considered. The final decision remains with the Ministry of Defense, which is the customer.

We have already tested three prototypes on which we obtained results, and today we say: thermodynamically, the machine has succeeded (...) The gas generator of the PD-8 engine can be used as a gas generator for the engine of a new generation of the Mi-26 helicopter

- leads TASS Shmotin's words.

In 2019, Deputy Head of the Ministry of Industry and Trade of the Russian Federation Oleg Bocharov said that a new medium-class PD-8 engine is being created in Russia, the development is based on technical solutions implemented in PD-14. The engine is being created to replace the French SaM146 on the Be-200 amphibious aircraft and for the Sukhoi Superjet 100 (SSJ 100). The PD-8 type certificate is to be received in 2023.

The PD-8 bypass turbofan engine is created using the latest Russian materials and advanced technologies, including 3D printing

        But they didn’t say anything about the PD-35. Yesterday, the UEC held a presentation of the PD-35 engine. development of about 2022 critical technologies, among which one of the key ones is a PCM fan blade. In 35, Alexander Inozemtsev said that the transition from a solid titanium to a hollow titanium blade made it possible to reduce the mass of the assembly by 35%, and the use of a composite blade would save another 18% in mass.

        From the presentation of the general designer of UEC-Aviadvigatel, it follows that the PD-35 gas generator has a 10-stage compressor and a two-stage turbine. For the first time in Russia, a fan with a diameter of 3100 mm will receive blades made of polymer composite materials.


        In the presentation of Alexander Inozemtsev at MKD-2022, several options for extra-high thrust engines were presented. These are the PD-35 with a thrust of 35 tf for aircraft of the CR929 type (take-off weight up to 245 t), PD-38 (thrust 38 tf) - for possible remotorization into the twin-engine version of the Il-96-400 (weight 270 t, more than 350 passengers), PD -28 (28 tf) - for modernized and promising super-heavy transport aircraft with a take-off weight of 400-450 tons and a payload of 100-150 tons, PD-24 (24 tf) - for a promising transport aircraft with a payload of 80-100 tons, as well as industrial gas turbine plants GTU-20PD and GTU-33PD with a capacity of 20,4 and 32,7 MW.

        . - In PD-14, only one was made using additive technology - a swirler, but in PD-35 there will already be 50 of them?
        - Yes, it is necessary in order to withstand the parameters of the engine. PD-35 has a fan with a diameter of 3,1 meters. The bypass ratio is 1,7, which is a very large coefficient. Dry weight - 7550 kilograms, compression ratio - 53, reduction of harmful emissions - up to 50-60 percent.


        .For PD-35, will the blades be cast or grown?
        - Some will be cast, and some will be grown using additive technologies. For PD-35, a material is needed that will operate at a temperature of 1350 ° C - this is necessary to remove the cooling of the turbine blades. The turbine blade operates at a temperature 400-500 degrees higher than the melting point, due to the fact that it is effectively cooled. And it is necessary to create either a very complex cooling system, or a material that, due to its chemical composition and structure, will work without cooling. And, of course, you can use various metal, ceramic composite materials that ensure the performance of parts and structures at high temperatures.

            Well, about the coolness of Boeings after 737 max, which are still laid up and an epic failure with a dreamlaner - it would be better to keep quiet ... And so - in terms of price / quality ratio, as well as in terms of service - they are an order of magnitude cooler. Because the service in Boeings and airbuses is not only of poor quality (again 737 max), it is also regulated by the state.
            There is such Firsov, a member of the editorial board of Aviation and Cosmonautics as well as Equipment and Armaments. He has a Boeing - his favorite topic ... Read, for example, about congenital jambs of wiring on all Boeings from 737 not max and older. They all have the same jamb, which led to a complete reworking of all released models, which by that time had been flying for ten years with elevators not working under certain conditions. This is a coffin with wings. And there are jambs ... At the Boeing. Our nervously smoke nearby

          I'm talking about this failure - they delayed getting up at the same time with the Boeing and Airbus. For 10-15 years.

            Come on, back off. The lobby would simply not let us into the market - with any aircraft. This is best seen in nuclear energy - the United States and France simply CANNOT build nuclear power plants. GENERALLY! Even for themselves - they simply cannot, because they DO NOT know how. But they win tenders for the construction of nuclear power plants. And Finland, China, India, the USA - and so on - all therefore sit with contracts, but 20 years without a single built nuclear power plant - is it clear how we "lagged behind on a par with Boeing"?

          In fact, the Superjet has only 20% of domestic so far, so consider it a Boeing with a Russian fuselage.
          And in 2000, the share of domestic aircraft was 90%, the domestic Tu-204 and Il-96-300 were already being produced, the Tu-334 and Il-96-400 with an extended fuselage were ready for production, it was possible to start producing the Il-114 , for example, at the Saratov aircraft plant, which was demolished ten years ago by United Russia. But Boeing brought the dough to the government of the Russian Federation and the FSE.

          No one interfered with recreating the fully state-owned airline Aeroflot with a network of routes throughout the Russian Federation and purchasing only our aircraft for it, producing Tu-204, Tu-334 and Il-96-400 and creating new Superjets and MS-21 aircraft to replace them, only in the Tupolev Design Bureau, which has experience in the creation and maintenance of civil aircraft, as well as a replacement for the Il-96 based on MS-21 technologies and new PD-35 engines. These planes could be sold to Iran, Cuba and Venezuela, and even to China.

            Let me remind you what happened to our aircraft in the 90s. A campaign was organized in the Western press to discredit our aircraft. It was said about too noisy engines and high fuel consumption. Our country "was part of the Western world," therefore, the road was cleared for Western technologies, as a result, the production of our own civil aircraft practically ceased, and Boeing and Airbus products poured into our market. As a result, we have complete stagnation in production, and Western firms have delivered about 700 aircraft of various modifications to the Russian market. Now, due to the current political situation, the pendulum has moved in the opposite direction, we are again reviving our own production.

              And I remind you that in the 90s it was not about all or only our aircraft, it was about old aircraft such as Il-86, Tu-134 and Tu-154, our Tu-204, Tu-334, Il-96 and even the Yak-42 passed these requirements perfectly and still pass them, because the Tu-204 is an aircraft similar to the Boeing 757.

              The collapse of our aviation industry did not happen in the 90s, but in the mid-2000s, when a lot of money appeared in the country and Boeing brought money to Medvedev, Shuvalov, Manturov and Gref, who lobbied for the purchase of Boeings and Airbuses, destroying our aviation industry. All these characters are still not only at large, but also sit in high chairs, they also manage our aviation industry, and they sabotaged the purchase of our aircraft until the last.

              Aircraft manufacturing is not the production of nails, it is a very complex production that not all the leading countries of the world have. It was very easy to destroy it, but it is very, very difficult to restore it, and these people will definitely not be able to do this. Look at the production of new IL-76s, 2 units per year. The plant in Ulyanovsk for 10 years after the start of production produced many times more An-124 Ruslan per year than now, 10 years after the start of production, this plant produces a much simpler Il-76.

        Yes, I am parallel to the cons.
        And in principle, imported machines are quite satisfactory both as an adjuster and as a technologist, including in terms of price. But now the question is even with South Korean machines, not to mention Japanese and European ones.

        A separate question is about how these machines are used, in most cases, even a "private trader" without investments can increase productivity by 10-20%, with investments up to 50%, and even "in the defense industry" in places at times, and there is no need to run with bulging eyes in search of new machines.

        The quality, and level, and even the price of domestic machine tools are frankly depressing.
        Without a sensible state policy, nothing will come of it in this direction. There is no accurate and high-quality large-sized casting, there is no modern production of ball screws, there is no modern electronics and automation (the baltsystem tried something, but how will they have it under sanctions?), not to mention the components of electronics and automation.

    It's all wonderful.
    But we have trouble with the production of means of production.
    Not to mention the production of means of production of means of production.

    What equipment do they use for 3D printing? From what materials?

    Blades and impellers are milled on whose machines and whose tools?

    About the production of means of production (I apologize for the Marxist term, I don’t know how it is commonly called today), and so, not a word about them AT ALL. Reports"Made in Russia"- yes. And on what and with what it was done - silence.

    As I understood from the article and comments, before the serial production of engines, at least 5 years. Cool

    The world rests on optimists :), Saturn in general, and Shmotin in particular, failed all projects, that is, absolutely everything. The plant lived by selling the Soviet D-30 to China and drank dough for R&D, passing off products from Nikolaev as their own.

    Here's what I know for sure. If there are a bunch of problems of the same type, then if you stick to the solution of at least one, BUT to the end, then it turns out that several others have been resolved automatically in parallel. Such a chain reaction. If all the problems with the development and mass production of the PD-8 are completely solved, several key tasks of our aircraft industry can be solved at once on the basis of it. Similarly with the solution of the problem of production of domestic electronic components. The decision of one will give impetus to the decision of others. We have many talented people.
