They overlooked the paramotor engines of Alida motors.
TEI shouldn't even be bothered by this project at first place but they have been because nobody else did.They overlooked the paramotor engines of Alida motors.
The company had even renewed its website.

Other companies do not have the vision of the possibly high numbers of demand for such a product and they do not want to spend RD money on it. But 50 hp is the magic number for single seat airplanes.TEI shouldn't even be bothered by this project at first place but they have been because nobody else did.
Altay‘s Batu engine is far from being ready. Are they going with a hybrid solution for Altay as well?
Welcome PD-180 to the dual turbocharge (DT) league, i guess.
Really wonder 30kft power, sfc and weight of this engine.Welcome PD-180 to the dual turbocharge (DT) league, i guess.
Mr Özsahin from TEI: "How can we locally develop materials, subsystems and components that we consider strategic? For this, we have three or four different teams established on the basis of directorates. Their duties are to first develop technology, develop materials and process technologies, and then turn it into a product. In other words, we apply the technologies we develop to our engines. The rate of locality in the next engine we build is always higher. The most difficult subject in the defense industry is aviation. The engine is also the most difficult subject of aviation. In this context, only four or five places in the world have this technology. The dominant powers in the world in this regard are the USA, Canada, England, France, Russia and Ukraine. We are on the way to making engines with more than 10,000 (lb?) thrust. Of course, these works by TEI are seen as a threat. In this context, we encounter various obstacles."
Mr Özşahin : "We have come to the level where many sub-components and motors are made by adding the knowledge on top of each other. All of our additive manufacturing has been activated. We made the first super alloy forging point in Turkey. We did the casting. We make the engine control system locally. This is the brain of the engine. We make the gearbox. We are currently working on lubrication fuel systems. Engine sensors are critical. We are still working on that part now. In our next engine, our technology at the subsystem and material level is one step ahead."
"We started mass production in the piston engine family. The development of our turboshaft engine continues. We will also have new engines in the future. When these engines meet with air platforms, our technological independence will reach a higher level.
We can now build UAVs that can patrol the world, from Kazakhstan to Morocco. And this, beyond the nationalization-localization move within the Republic of Turkey, allows nations that are tired of the dominant powers to look at us with the eyes of hope. Tired of being exploited, they seeks an alternative. Turkey will become a focal point and a center of attraction for some of the 200-odd countries in the world in 10, 20 years."
That is why self-suffeciency is importantMr Özşahin from TEI:
"Aviation means materials. For example, India has been trying to make engines for about 45 years. Finally they couldn't, they gave up. They even tried to get help from the French. They redesigned the engine. They said, let's give it a billion euros. But they can't. This is because the engines are very heavy. They don't have material technologies, they couldn't make their software. Therefore, this is the plane they developed Tejas, but the engine they call kaveri could never meet that plane, despite the support of the French. Again, they had to go and install GE's 404 engine. That's why the work we do at TEI is very important.
The turbine blade is single crystal, the most important technology of this engine. We did this together with TÜBİTAK. We received it, we are using it. Under normal circumstances, these Rolls Royce, GE, Safran authorities will not let you pass the facilities where single crystal turbines are produced. Because technology is hidden. Leave CAATSA, the embargo, this is a secret technology. We are doing this right now. Again, the castings of our engines for unmanned aerial vehicles; England blocked the cooperation for various reasons. We did this in a very short time, we developed it. It is now active. BAYKAR, TUSAŞ institutes are flying with those engines very frequently. The UK has a clear embargo. Germany also has a secret sanction. But we also developed that product, it is currently at the prototype stage. It will be used in our engines."
India's case was differentIndia has been trying to make engines for about 45 years. Finally they couldn't, they gave up. They even tried to get help from the French. They redesigned the engine. They said, let's give it a billion euros. But they can't. This is because the engines are very heavy. They don't have material technologies, they couldn't make their software. Therefore, this is the plane they developed Tejas, but the engine they call kaveri could never meet that plane, despite the support of the French. Again, they had to go and install GE's 404 engine
India's case was different
We went a lot optimistic
Without having sufficient fund,facility.
India spent only 2 billion usd for development of kaveri without test facilities.
What did we achieve?
Kaveri helped us to advance our R&D of turbofan engines,intact now kaveri most issues have been resolved and if they can decrease weight it can be put to tejas.
Kaveri helped to such an extent even if foreign player is not involved India will crack the high thrust engine headache
But obviously it will take another decade eventually+fund distribution and proper management is required.
French did give us offer for kaveri but it was not accepted because they were demanding high cost.
It was big mistake by India by not going phase wise for engines,but alas it's never late.
We will reach there eventually
It's interesting to see Turkey is also moving ahead with high thrust turbofan engine R&D,you're right about that part that big powers won't provide tech.
Not the right threadDid India have smaller scale turbofan or jet engine projects before starting Kaveri ?
Did India have smaller scale turbofan or jet engine projects before starting Kaveri ?
Not the right thread
But as far as I know
We directly jumped to kaveri.
We did not even have smaller turbofan programs.
Manik(stfe) and hal derivatives came later.
