Ankara, Turkey – Aircraft turbine blades produced by TUBITAK MAM in single crystal form and delivered in sets for the first time will be used in TEI’s No. 5 TS1400 engine.
TUBITAK MAM Materials Institute High Temperature Materials Research, Development and Repair Excellence Center held at the single crystal turbine blade delivery ceremony, TUBITAK President Prof. Dr. Hasan Mandal and TEI Chairman and general manager Prof. Dr. Mahmut Aksit and the researchers involved in the project attended.
In his speech here, Prof. Dr. Mandal said that the single crystal turbine blades, which are among the most critical technologies, were successfully produced as a result of the joint work of the Materials Institute and TEI.
Pointing to the difficulty of having single crystal technology, pegs pointed out that they mentioned a material that would work at a temperature of 1400 degrees, under high pressure and in a corrosion environment.
“Therefore, besides the production here, I think that the competence and capability we have gained here is also important at the point of the development and sustainability of material technologies in our country, especially in the defense industry.” said.
Working under difficult conditions and sometimes impossible to import, they developed turbine blades together with TEI and delivered the first set.:
“This is really an important win for our country. It was always said about domestic and national production: ‘Yes, you have a helicopter, but is the engine of this one native?’ Yeah, now TEI can produce it locally. Yes, there is an engine, but can the components inside the engine be produced locally and nationally? Yes, we are now able to produce turbine blades, which are the most difficult component of our country’s first domestic and national turboshaft engine, by TUBITAK MAM.
This technology is very critical, and a very limited number of countries around the world have this technology. It’s a very complex and difficult design, it’s not an easy process to make them. We accomplished this. Of course, this is not a process that ends. Gotta Have a sequel! TUBITAK Materials Institute and TEI signed aviation engine materials development-ore project will now be able to produce nickel-based superalloys for these and similar applications starting from raw material.”
TEI Chairman and general manager Prof. Dr. Mahmut Aksit also said that while he was a faculty member at Sabanci University, he was also a member of the Board of Directors of EUAS.
At that time, they attempted to produce industrial gas turbines that produce energy, and thus brought the infrastructure in question to TUBITAK MAM, Aksit said, after passing to the General Directorate of TEI, one of the most critical parts is the turbine blade again because it contains high technology, “export control” is a product.
Aksit, even if they sell the wing itself, they do not share its technology, how it is produced and such things, noting that they decided to develop the wing technology here because they know the infrastructure that TUBITAK MAM has, he said.
Aksit emphasized that although the ailerons used in aircraft engines are smaller, it is a process with higher technology and more difficulties, “thankfully, our friends at TUBITAK MAM Material Institute achieved this with the flow of their foreheads and gave us the wing technology we need.” said.
Aksit said that the delivered ones were not the first turbine blades produced by TUBITAK, These Wings were used in the engine they had previously delivered to Tai, but they could not perform the ceremony at the time.
“What you see here is a complete set of engines,” he said. Both first-stage single crystal, but internally cooled wings, which is much more difficult, and second-stage single crystal, but without internal cooling wings.
We aim to use it on our No. 5 engine. The engines we gave Tai earlier were delivered. This is a complete set of our number 5 engine. For the first time, it was possible to see it together as a full set.”Aksit stated that they have produced the engine No. 4 and their tests are continuing, “We delivered our First National helicopter engine, the TS1400, on December 5, 2020. These Wings will hopefully be installed in our No. 5 TS1400 engine. I hope they will work on the Gokbey helicopter., “he said.
Aksit pointed out that the first stage wings come in first place when the most critical parts in an engine are sorted, “then maybe the combustion chamber can come, then the second stage wings come in temperature and the difficulty of technology. The compressor side is also very difficult, but the most difficult is the first-stage single crystal wings. The most critical piece. If you can’t do that, I won’t say you can’t start the engine, and if you can, you can’t generate power. You can’t go to a high temperature., “he said. Aksit said about the function of single crystal turbine blades in engines:
“All jet engines, like other fossil fuel engines, operate by the expansion of heated air. How do we heat the air? By putting the fuel in it and lighting the match, we make the air warm and expand. And to make this happen, we need to take the air out of the compressor and compress it. If we do not compress the air to high pressure, the combustion event will be very slow and we will get much lower power than the same engine. The power we get per unit of time decreases. So we’re delivering it to high pressure. So that it burns more efficiently, that we get more output from the engine per unit of time. In this way, instead of using the gas ejected from behind in direct thrust, we turn some of the energy there into a rotational motion by hitting these hot wings, which absorbs the air in the compressor and supports the work of compression. Without these wings, the engine would not be able to work. So these blades run the compressor with a serious amount of power.” After the speeches, pegs delivered the first set of turbine blades to Aksit. Pegs and Aksit later worked at the high temperature materials research and development and repair center of excellence.
