But they do have experience in other turbofan engines which in principle works the same. And btw they do have a working afterburning turbofan engine the AI-222-25F. "By using a great experience gained in the development of AI-222-25 , AI-222-25F and D-27 engines the AI-9500F with a thrust of 9.5 tons of force is under study for using as integrated in the power plants of light combat airplanes.
You can read their enterprise history here:
If these well-known and all over the world understood principles could be turned into a working high end turbofan engine so easily, why then do the Indias fail since years, why is there not a single fifth generation engine from Europe ready, why do the Russians and Chines still have issues? Must be something that is not that simple … ANd concerning an enterprise‘s own history, this is well known, but more a marketing brochure than proof of what they can do today especially after the current crises.
What has China to do with whether Ivchenko Progress can meaningfully contribute to the co-development of the TF-141?
China wanted them for trainer/UAV and most of all helicopter engines, surely not for high-end high-thrust turbofan projects.
From what I understand about Ukrainian aero-engine industry is that they have experience and knowledge, but lack funding. A particular design that comes to my mind is the AI-9500F medium thrust engine aimed for the single engine light-weight fighter market that to me still seems in limbo. A Turkish (or from wherever) capital injection can revive Ivchenko Progress' developments. This investment creates certainty, especially after Motor Sich is providing Baykar and TAI engines for the Akinci, MIUS and T-929 (and presumably also cruise missile engines) for the value of $600 million.
This is a matter of controversial discussions but by my understanding they have not. This alleged AI-9500F is a paper-engine since years and nothing happened and even if they had the fundamental understanding of modern engine-cores, the level required for a true fifth generation type and the lack of experience in that certain area cannot be overcome so easily.
Says who? I get the opposite impression especially after last Septembers visit of Erdogan to Russia wherein Turkey and Russia made certain steps in engines, warplanes and especially aircraft engines according to Erdogan:
I know we again habe contrary standpoints, but what Mr. Erdogan says is IMO not relevant in terms of true capabilities and what Russia says also not. Just look how they still struggle to get the Izdele 30 running for the Su-57 and therefore as long as there is no real prove of the said cooperation and result of the promised things, I rate this as not reliable And more a political statement. By the way, do you really think Russia will accept any deeper cooperation with Turkey while at the same time Turkey sells UCAVs to Ukraine and co-develops other items with Kiev?
Indeed, there is no selling of such technology but co-developing certainly is a possibility.
The problem is, that Turkey starts not from the same level … as such any co-development would either include the transfer of technology they gained via GE and other Western companies or a de facto transfer of technology in order to bring Turkey up to the same level. And that what none of the others would do.
Again, I wish them to succeed, but by all my limited understanding, Turkey‘s will build and field such a fighter and a new engine is far beyond its abilities. But again, we‘ll see.
