but the Ukrainian way with a company that has de facto no experience in modern afterburners high-thrust turbofan engines
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:
was almost up for sale to China
What has China to do with whether Ivchenko Progress can meaningfully contribute to the co-development of the TF-141?
and now has an uncertain future is IMO a partner that only brings additional uncertainty
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.
and the reason for this way can only be than none of the other major players in aeroengine business are willing to provide their technology
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:
It seems Turkey is not going all in but tries to diversify its potential co-developers as the news about Ivchenkno Progress being a potential candidate is from last July as it was then for the first time mentioned in DT magazine issue 108:
You simply don‘t sell your crown-jewellery for a few $$.
Indeed, there is no selling of such technology but co-developing certainly is a possibility.
I know I‘m probably the most critical/sceptical one here concerning this project but this decision is only yet another reason to see it my way.
It has turned into cynicism
Anyway, all the best and time will tell.
This I agree with you.
