UMPO awarded for the production of blades for the T-50

UMPO and MISiS University were awarded a silver medal for a new technology for the manufacture of turbine blades and a compressor for promising aircraft engines. The new technology allows to reduce fuel consumption and reduce the level of noise produced.

The award was presented to the International Industrial Exhibition Metal-Expo-2013, the press service of UMPO reports.

New technology is used in the framework of the state contract at the expense of the federal budget.

The first experimental batch of parts was manufactured at the facilities of the Ufa enterprise.

Casting vanes from titanium aluminide is a critical technology. Without these elements it is impossible to produce aviation fifth generation engines.

The joint development of UMPO and MISiS uses this casting method to create high-pressure compressor blades of a promising engine for a PAK FA (T-50 fighter) and low-pressure turbine blades for a promising PD-14 civilian engine.

Thanks to the new technology, it will be possible to increase engine performance, reduce specific fuel consumption and reduce noise.

This is achieved by a twofold decrease in the operating centrifugal stresses in the compressor and the turbines of the engines and by reducing the inertia of the turbines and compressors.

"Ufa MOTORCONTROL PRODUCTION ASSOCIATION" - Russia's largest manufacturer of aircraft engines. Engaged in the development, production, service and repair of turbojet aircraft engines and gas pumping units, production and repair of components of helicopter equipment. It is part of United Engine Corporation - 100% of the specialized subsidiary of OPK Oboronprom, JSC for engine asset management.

The blades are simple and unpretentious at first glance, in fact this is a high-tech product that combines a whole range of technologies, from alloy to processing, essentially the most important part of the engine.

[Yuri Y.]

Under all other conditions, new technologies will pull us out of the economic pit. This is the hair for which Menhausen dragged himself.

[wow]

"Ufa-motor" is a very honest "office"! I have been there more than once or twice when I served in the USSR Air Force. I had to retrain on their basis for new engines and work with their factory representatives. Very competent, competent specialists. Then they produced izd. 55B (R-29B-300), these engines were installed on the MiG-27M (D). Good luck guys, well done !!!

The point is not, dear colleagues ...
And the fact is that in order to pull new technologies, you need to make a breakthrough of the entire national economy for a whole generation, including the "brain processes" of course :)))))))))
That's just the last problem ...
I remember a remarkable conversation with the guys with NPO Saturn (Wait UMPO holding, by the way :) about whether they acted recklessly at one time selling several AL-31 engines. It was 10 years ago ...
They answered like - we thought for a long time, wondered ... then they decided to sell it. They still have not really mastered the previous generation (Р13Ф300), but where is it ...

And with the blades there is one more feature - you still need to be able to calculate them in order to work in the 3x dimensional flow.
And this is the upper class, it is not without reason that the whole west is being trampled at the institute of aircraft engine building;)))

Sanya ..exclusively only for your phrase about .. "unlucky Chinese"

After 20 years of research, the State Laboratory of Advanced Metals and Materials has achieved the creation of a new type of high-strength heat-resistant material based on an alloy of niobium, titanium and aluminum.

China received independent intellectual property in this very promising alloy, which will allow "our aerospace industry to make a breakthrough and enter a new stage with the technological level of the leading countries of the world in this field."

This "superalloy" in its strength is not inferior to an alloy based on nickel, but almost twice as lighter, which will significantly reduce the weight of aircraft engines.
According to reports, the alloy niobium-titanium-aluminum will open a new era in the development of aerospace technology, ships, will be used in the automotive industry and other industries.

High-temperature materials are primarily used in the manufacture of turbine blades (compressors) of aircraft engines, which are subjected to extremely high temperature and pressure of the working medium.
One of the main indicators of the perfection of modern jet engines is specific thrust, that is, the ratio of thrust to engine mass.
Currently, most modern turbofan engines have an indicator of 7,5-9,0 to 1.
In this regard, the best in the world is the F119 engine (pictured) of the American F-22 fighter (11,0 to 1).

The ability of an alloy based on niobium, titanium and aluminum to withstand ultra-high temperatures will increase thrust and at the same time reduce the weight of the power plant, which is very important for the development of China's aviation industry.

By the way, I will paraphrase an old anecdote. The Americans bought the newest disassembled aircraft in Russia. They brought it to their place, assembled it - it turned out to be a steam locomotive. Well, they thought that they had done something wrong, disassembled, reassembled, the result is the same - a locomotive. Well, they think these Russians have deceived again. They call the plant and say, "Guys, what did you sell to us, we wanted to buy the newest combat aircraft, but it turned out to be a steam locomotive? !!!" They are answered from Russia "Have you read the assembly instructions carefully?" "Yes", "If yes, you saw at the very bottom written in small print a note:" AFTER ASSEMBLY, CAREFULLY PROCESS WITH A FILE "

By the way, the modern blades can be manufactured by the Russian Federation, the USA, England and France, even such a technologically advanced country as Japan cannot produce them. I am glad that we still have some technologically advanced areas.

[mirag2]

Yes, this is a very complex detail - my brother studied at the Moscow Aviation Technology Institute. Tsiolkovsky-told a long time ago about this, that's why I am against the Chinese transferring engine production technologies.

All Asian and Pacific powers need to unite in a good way to control the import of goods and technologies to China in order to ensure controlled technological lag. We all understand that no one needs a strong China. Therefore, we must first cut China off from modern technology, and then systematically reduce the technological level of China - until it returns to its natural state - as before the Opium Wars

The internet is full of information. The military are of course clutching, but you can find anything.
For example, a drawing of a Rolls Royce Trent 900 engine installed on an A380, let's say not quite an old model

[stayer]

So it is true, but there are no drawings of blades and never will be. Only approximately or schematically, for understanding the process. And from what alloys, casting, cooling, grinding, hardening and other operations you will not find. Or there will be well-known facts from the middle of the last century. Not for nothing that the Chinese can not repeat. They do it only at the level of just the middle of the last century.

European crisis: Greeks infect themselves with HIV for € 700

Unemployment in Greece remains one of the highest in Europe. Some people in the country intentionally infect themselves with HIV to receive € 700 benefits from EU authorities

“People themselves infect themselves in order to receive € 700 payments from the European Union and quick access to substitution treatment programs,” the organization said.
In addition, the economic crisis provokes an increase in crime, which contributes to an increase in the number of drug addicts and the spread of HIV. The number of murders and thefts during the economic crisis has doubled. In addition, the number of prostitutes has risen sharply in Greece, WHO notes.
Public access to medical services decreased by 40% due to cuts in the healthcare system. This leads to the fact that the Greeks are less likely to visit doctors. According to EU studies, from 2007 to 2009, residents of the country became 15% less likely to seek medical help.
The Greek government continues to take steps to reduce the number of workers in the health system. Only in the process of the planned "budget optimization" the country's authorities plan to lay off 26 thousand employees, including more than 9 thousand professional doctors.
“The situation in Greece should be a warning to other countries that have to reduce the budget deficit, namely for Spain, Ireland and Italy. It’s necessary to find a way to consolidate finances without abandoning the necessary investments in the health sector, ”the WHO report says.

Oversupply in the wrong direction of engine development. You will forever modernized the scapula, and the results are on the verge of critical achievements. The issue must be resolved radically in a new way. Change the flow of hydrodynamic flow in an alternating magnetic field. Everything is simpler and orders of magnitude more efficient. Toda, all cavitation processes will occur not on the plane of the scapula, but on their radial end. And the same energy as potential can be further converted into a new algorithm of magnetic interactions.

Guys !!
I'll be honest. Believe it or not. Personally, I don't need any electrician. I am so used to working with an ordinary hand-held sheet hacksaw. The main thing is that the tool is always well sharpened. But there are no problems with this - for this we have a household in the court. the part where a locksmith for a half liter of alcohol will sharpen the entire section set every day. : D And I still have enough free alcohol (pah-pah B)) ...
Yes, of course, for a novice-orderly "hand" hacksaw is an everyday torment. I know this very well, because I myself went through it. But over time, skill, experience, and dexterity appear. And cranial bones of any thickness have long been no problem for me.

Forgot to add. About the shoulder blades. Why the material was so named, you need to apply to the Ufa Engine-Building Production Association. There they will tell you everything, show you, but most likely, they will not let me go further than the entrance.
The intermetallic compound is obtained by alloying titanium and aluminum. The second name of the material sounds like that - titanium aluminide.

The invention relates to the field of metallurgy, in particular to alloys based on titanium aluminide, manufactured using casting technology or powder metallurgy. The alloy contains titanium, aluminum, niobium with a niobium content in the range of 5 × xxAt% and carbon in an amount of less than 2203339 at%. The technical result of the invention is to increase the heat resistance of the alloy , which will allow the use of the alloy as a replacement for nickel-based alloys. 220333910 s P. f-ly, 0,5 ill.
To further increase the strength of the alloy, it is preferable to add carbon and boron components to the alloy of titanium, aluminum and niobium, due to which, in addition, the aluminum content in the alloy can be 45 at.%.
An advantage of the solution according to the invention is that, as the tests show, a significantly higher strength can be achieved in the temperature range up to 900 ° C and higher, that is, at such operating temperatures to which the alloy according to the invention is exposed, namely compared to previously known alloys based on the mixtures of titanium aluminide used so far.
Another significant advantage created by the proposed solution according to the invention is that the oxidation resistance of the alloy is significantly greater compared to the hitherto known alloying mixtures of the type mentioned in the restrictive part of the claims, that is, in total, the alloys proposed according to the alloy is suitable for other additional applications, for example, for use in high-performance turbines for jet engines in civilian and military aircraft.

On the issue of alloy quality. You did not provide data on the Chinese alloy, what percentage of components in it. Therefore, talking about whose alloy is better is pointless. I gave an example, mind you, the alloy for which the patent was obtained. keyword patent i.e. This material was actually made and tested and patented 12 years ago. This is an indisputable fact. I will say a little more, without giving out any secret))))). Along with the main components of the alloy of titanium, aluminum and niobium, in order to increase the strength at high operating temperatures of parts made of alloys, i.e. up to 900 ° C, boron and / or carbon can be added in an amount of less than 0,5 at.%. And that was the previous generation of materials. Now the gas temperature in front of the turbine barely reaches 1950 K, and in new engines it will reach 2000-2200K (1927oС). High-temperature alloys have been developed for them, containing up to fifteen elements of the periodic table, including rhenium and ruthenium, and heat-protective coatings, which include nickel, chromium, aluminum and yttrium, ceramic made of zirconium oxide stabilized with yttrium oxide.
Let’s say softer here, these alloys are improved, plus, as I said, the use of ceramic coating.
If the mattress technology was better, they would not come to us))))) But the titanium-aluminum alloy is, of course, not exclusive. Exclusive alloys made on its basis.

In the mid-80s, I had a chance to touch the topic of ZhSs. A little - I measured the density of melts from Melting to 2200 according to C. I remember: continuous empiricism and no science. Stupidly, various elements in various concentrations were added to the already known composition. Then they tested in VIAM. Interesting: in our time there is some kind of scientific approach to development. Well, like: is it possible to predict the properties of the alloy theoretically? But there were more elements. I remember, until 17. I understand that I’ve got into a topic, .. But still, Roman. If it’s not difficult, then in a word ... I just forgot about it, and here you reminded ...

everything is correct, now VIAM is working in close contact with TsIAM. Some brains complement others. And the preparation of new formulas takes place as before on the knee)))))) No, I do not argue, there are mathematical models of interaction at the atomic level of various materials. But these are only models, in real life, when connecting simulated components, the expected does not always work out. So, basically, these are experiments on sort of adding one to the other and pouring in a third substance, and it’ll turn out to look cheat)))) Although it’s much easier now, there are tried and tested models of blanks, so to speak, the foundation on which other components are planted.

[pensioner]

Thank you Roman!

[gridasov]

It is absolutely true that there is no mathematical model of modeling, not that of multicomponent materials, but about the modeling of dynamic processes and the transformation of matter, it’s similar. Until there is such a mathematical model, everyone will stagnate.
For example, we created the concept of radial computing and experimented with screws. That is, mathematically modeled all the cumulative processes occurring not only in each component of the process, but also group and complex interactions. Note that the model must comply with a one-time accounting of all changes and transformations. The conclusion is that it is possible and not very difficult to create such a device that will not have all the flaws that are on the screw, and accordingly on the turbine. And the main disadvantage of modern devices is the very low limits of non-destructive rotation. These boundaries can be theoretically and obviously almost completely removed. But this is for specialists.
