Russia has tested new material in the aircraft engine industry

53
Rostec Corporation reports that the Moscow Salt Research and Production Center for Gas-Turbine Construction, part of the UEC (United Engine Corporation), has conducted research in the field of materials science. We are talking about research work, which should serve to obtain new materials when creating aviation engines.


The press service of the company reports that the research work is related to the study of the properties of the new Russian binder material alumox. This material is considered as a potential basis in the process of creating blades for aircraft gas turbine engines.

Valery Mikhailov, deputy head of the metallurgy sector at Salyut NPT, notes that improvement of blades for aircraft engines based on nickel-based superalloys has reached its limit.

Of statements Valery Mikhailov:
At the same time, the high melting points and reactivity of a number of composite alloys lead to their interaction with most refractory materials. The possibility of using for these purposes traditional ceramic materials is almost completely exhausted or, at best, significantly limited. For reliable implementation of the high-gradient directional solidification process, it is necessary to increase the operating temperatures of the crucible and the ceramic form to 1800 degrees Celsius, which is almost 200 degrees higher than in industrial technology.


Russia has tested new material in the aircraft engine industry


Providing temperatures up to 1,8 thousand degrees Celsius requires the use of a silica-free binder and refractory refractory materials (talking about yttrium, zirconium, aluminum oxides). It is such a silica-free substance (alumox) that was developed by Russian specialists from the Department of Technology and Computer Aided Design of Metallurgical Processes of the MAI.

Tests of alumox showed that it has excellent resistance to temperatures up to the above mark, while it also revealed chemical inertness.

From the material:
Studies of high-pressure turbine blades of the AI-222-25 turbojet engine showed that when using even a combined form with two protective layers on a bonding aluminox, the depth of interaction between the casting metal and the mold is about seven times less than on blades manufactured by serial technology, and does not exceed 5 microns. Thus, the use of ceramic forms with alumox will significantly improve the quality of casting and, accordingly, the working properties of the blades, affecting the performance and GTE resource.

      the matter is not the amount of money, the fact is that with us this money cannot be received by those who are real and are engaged in creating new and useful things. All patents protect only corporate income, but it is problematic for an inventor and / or researcher to get money. As a rule, they can receive income only in the form of orders for research or the purchase of a patent if it does not allow any corporation to earn money, but all these are such miserable amounts in relation to the work done that it is easier to get to hell and establish your own small company and recapture the invested resources on petty income.

            The largest farm in the country for the cultivation of Pacific white shrimp has opened in the Kaluga village of Kollontai.
            100 million rubles were spent on its creation. The growing process is almost completely automated. Shrimps are grown in tanks under conditions identical to the natural environment. In an incubator, up to 30 thousand fry can grow simultaneously. They are now being brought in from Europe and the USA.

          In Belarus production(rather than growing) shrimp in large volumes has been going on since the 90s of the last century.

        ... and even with the correct molecular calculation of the above materials according to the ps scheme (for counterclockwise torque) we provide molecular conjugation (field) to reduce the mass of the platform from the blades and then (including the duty cycle of course) gravitational and therefore inertial environment within a radius of 1,8m.

      Is the material new? New. Is it used in engine building? Used. After all, it is not written anywhere what engines will be made of this material. If engine parts will be made on a new machine or using a new tool, then this machine and tool are used in engine building. I consider your claims far-fetched.

    Yeah, the article is superficial ..
    "Shovel" is a complex aggregate process. The creation of a “high-temperature" turbine blade of an aircraft engine, on which thrust and specific consumption depend, has been the problem of aircraft engine manufacturing ever since the jet engine appeared. In this we began to lag back in the 60s. Now, it seems, already at the near level.

      Maybe in some ways we lagged behind technologically, but you completely incorrectly gave an assessment to the technological concept of the USSR in the construction of jet divers. NATO was very surprised by the RD 33 blades when they got the Gadjer MiG-29s. After that, they made many different body movements at the level of contacts with the manufacturer and developer of the technology in order to understand how the processes of development of directed crystallization and the growth of such single crystals were implemented in the USSR. The effective cooling coefficient of our blades was already then 0,5. And by the beginning-mid-90s, the goals were to reach 0,7 - 0,8, since it was planned t> = 2000 degrees in front of the turbine. But then the USSR gave a hitch and today (in 2017) they report to us about what the USSR should have technologically approached a year later in 1995. And if we had done so (and not destroyed the country), we would have kept parity with Yankees in this area. And today we are at least 20 years behind.

        Well, NATO has nothing to do with aircraft engine manufacturing. They are the operators. And the USSR is not an argument. The argument is who first made the blades with "ventilation" channels. I am a patriot in life and I understand that in many ways, we are still living on the foundation of the USSR.
        But I know firsthand our lag in aircraft engine manufacturing (to my great regret). I really want to live up to our engines - highly efficient with a thrust of up to 35 tons (PD-35). yes hi

The main thing is the thrust that provides the task for the created VS. We always chased the quantity (forcedly), sacrificing quality. As a result, they missed the breakthroughs of the West in production technology in the aviation industry, which has always been an industry of advanced technologies that provides "power" for other industrial sectors.

    Something in the material of a lot of stocks.
    As for the Soviet heat-resistant alloys, they were approximately 15% more heat-resistant and 10-15% more heat-resistant than imported “nonmonics”. Well, in principle, you can still raise the characteristics a little - but why? It will be too expensive. It is easier to apply heat-resistant coatings, including from special ceramics based on zirconium oxide. And yet you will smile, but before the collapse of the USSR, Belarusians commissioned KNPO Trud (Kuibyshev, now Samara) and Lytkarinsky Saturn developed this technology and transferred it to the plants. The thickness of ceramic coatings varied along the contour of the blade and reached 0,3 mm in the most heat-stressed places. Along the way, we found a marriage in the manufacturing technology of nozzle blades for the SU-27. The blades with thermal protection passed the whole range of bench tests with a running engine, showing a five-fold increase in the resource (on the stand). After the collapse of the USSR, the Russians no longer turned to Belarusians. If anyone is interested, then about the latest developments of the Belarusian school of thermal protection, including on meteor protection, can be found in the journal "Science and Technology" (BNTU Publishing House).
