Main points of the M F Aksit interview:
1. PD170 ; Currently in use on Anka there is now a PD180 model in the works , 10kg lighter but will have more power for TB3 Bayraktar.
2. PD222 ; Already Ank has flown with it. Aksungur too. This engine will also be used on a lighter longer endurance model of Akinci.
3. TJ90 ; Was originally a test bed to see if an indigenous turbojet can be produced. Success ended with the use of the engine on “Simsek” target jet drone.
4. TJ300 ; Was a test bed for an axial flow jet engine. It turned out, it could be used as an engine for Medium Range Anti Ship Missile.
5. F110 ; All Turkish F16 engines were put together in TEI with a handful of pieces actually produced in situ. But Today more than 50% of all critical parts of that engine can be produced in house and the complete engine can be put together with some minor parts outsourced. In fact the TFX will have an indigenous engine. May not be the first plane but the one after definitely.
6. CFM, RR, P&W and GE all use TEI large blisk technology. In fact there are some critical parts produced by TEI on at least 50% of all the aircrafts today that is in the air, be it civilian or military.
7. TS1400 ; there will be 6 or more prototype engines whereby small glitches will be ironed out during the integration process. Then there will be a qualification process for the engine. This will take around 3 years. But this engine has opened the way to produce much bigger and more powerful engines for us. Be it gas turbines for ships, turbofans or turboprops.
Much appreciated. Teşekkür ederim.
Also thanks to @uzaysan for his summary here:https://defencehub.live/threads/turkish-propulsion-systems.3/page-27#post-46778
W.r.t RR and PW "using" TEI large blisk tech (as GE + CFM using it is a given), it would be interesting to get some further clarification as to what exactly this means (and what definition this is referencing as video is given with layman in mind it looks like).
There most certainly has, is and will be innovation process flow though from TEI given the scale of what has been sunk in (I will have to check with a higher up w.r.t this later and tell you folks for PW specifically if we can know)....more on that later in this post.
As for the 50% of all aircraft (commercial engines) having some TEI part in it, its not surprising given the vast scale of GE + CFM MRO (737 and A320 engines prevalence is immense in aviation) and now the time that TEI has been involved in the sector too.
Not too many know this, but we big 3 (PW, GE, RR) cooperate in every combination on certain things...along with harness/deploy wr.t. our subsidiaries/affiliates/JVs/suppliers/MRO.
i.e GE-PW, PW-RR, GE-RR and GE-PW-RR all exist (I can tell you specific history and famous names/teams regd this but it will get too off topic)...so we have things that process flow from these collaboration combinations, along with things we guard/innovate more tightly to just ourselves.
But AFAIK, here at PW we source (either blisks directly or the standardised capital tech + process for new/changed line for current and next gen engines etc) near-entirely from MTU (Germany) who are kind of the "OG" on blisks at large (They made the biggest breakthrough in early 90s on friction weld scaled reliability which is long story in itself)
RR has plant in germany (Oberursel) similarly for its blisks.
So what has flowed from TEI now (given long years of operation at the requisite level) to say RR and PW, I will have to look into it.
If anyone has any further info on distinct + precise TAI/TEI related innovation w.r.t Blisk (if such article/material exists open source), I would be most grateful.
A bit later I will be looking for some papers from Turkey concerning it if I can find them (or anyone provide/post them here or to my inbox etc).
In summary, TEI (a JV between TAI and GE) will be large principal provider of Blisks for GE and CFM among others (and Turkish and other militaries etc).
So congrats to Turkey. I am very impressed (esp considering further details below):
Here is good article about such examples of innovation w.r.t TEI + GE TTC that should hearten any Turk reading it (and I am glad Canada contributed to Mr. Caner Eskioglu one hehe):
An oasis of innovation - The GE Aerospace Blog | Aviation & Flight News
When you look at Istanbul for the first time as the plane approaches the Ataturk Airport, what’s striking is not just the vastness of the city stretching below your eyes. It is equally impressive to fly over that sea stripe drawn in the Bosphorus Strait, with the Asian continent to the left and...

Small bit (whole page is good read):
Even inventors can be found among the young people of the TTC, in true Edison style (GE’s career program for young engineering talent at the TTC is widespread). Caner Eksioglu is from Istanbul, but he completed his degree in Vancouver, Canada, leaning toward aeronautics and, for the last six years, has been working in the TTC team of Machining and Model Based Manufacturing. “We design and develop improvements for processes aimed at removing material from blank, or closely formed, shapes to create or repair aircraft engines and aeroderivative engine parts. My daily job is 50% engineering and planning on the computer (Design, CAM, calculations, programming etc) and 50% hands-on (machine validation, cutting tests, inspections etc). One of Caner’s latest innovative engineering solutions is software which calculates the optimum stock for LEAP, GE9X and GEnx blisk parts machining: the latter are engine turbine parts where blades and the disk are integrated. “Probably, ten years from now, we will be designing new engines not in years but in just a few months. We will be manufacturing parts not in months, but in just a week,” he said talking about future perspectives. “Engineering teams like us will put more emphasis on digital technologies (math-physics based quick solutions, digital twins), smart factories (robots, industry 4.0) and new fast manufacturing technologies (additives)”.
He actually sounds lot like guys I have worked with here at PW (and what I have also done at stretches earlier in my career and still now in different way) and what I described partially earlier in the thread (optimisation + process flow w.r.t CAD/CAM).
So great to see folks at GE TTC and TEI finding and implementing innovation on the fly....and it feeds back into the larger GE and aeroengine sector ecosystem over time for all mutual benefit.
Video at end (all so similar to PW, hopefully some of this tech I will cover in more detail in jet-eng. thread):
The original video by the (managing director?) Mr. Aksit makes lot more sense to me, thanks (to everyone so far that posted and helped me out)...we eventually got there in the end heh.
My intuition definitely originally underestimated the scale of what TEI doing/innovating (I did not know about this GE TTC for example, makes sense now)...it makes me want to visit Istanbul area in a different sense for next time heh
....honestly (looking at map) I didn't know Istanbul on Asian side extends that far south-eastwards (Gebze etc).
It looks like the main production facility for TEI is at "Eskisehir" further interior into Turkey.
Mr. Aksit video for reference:
UAV/UCAV Programs | Anka - series | Kızılelma | TB - series
selling to serbia is foolish. How often do we find serb weapons in the hands of the PKK?

If anyone has any way to give feedback to TEI etc, would appreciate if they can put english subs next (or a re-release with it)...as autotranslate CC is ..though I enjoyed the shop floor visuals etc. Thanks.
@xenon5434 @anmdt @Sinan @UkroTurk @Webslave @Saithan @Test7 et al (I think many more will get auto alert anyway)
