This?
What engines attack helicopters will use?
T129 is using CTS800 Honeywell. But the proposed replacement , T626 probably will use militarised TS1400.
T929 will initially be using Ukrainian MotorSich engine shown here two days ago. In serial production though a 3000hp engine (TS3000) will be flying this helicopter.

Very good interview with Prof Aksit.
He explains about the mid section of the 2000shp T700 engine. How TEI engineers managed to produce a 300+ piece mid section unit with a 3D printer as a single piece. This in it’s own right is a groundbreaking technological advancement of Turkish turbine engine building. Current Turkish T700 helicopters are having their engines with this mid section.

@Lonewolf for your benefit: He once again reiterates that as TEI they can manufacture much larger engines. And that they know the difficulties that come with when manufacturing larger engines.

It's turboshaft buddy 😐😐 , and they aren't single crystal blade ,the main challenge is SCBs .

They know difficulties ,means they know what to do ,but they haven't done it yet , it will take time to reach the level required and lots and lots of money , whole rnd and production can reach 6 billion+ easily ,not including any issue propping up (hope it don't happen ) , which might means back to square one if issue is big .

These things take time and efforts , this will be litmus test of whole turkish aerospace ecosystem involved in this project

Turkish turboshaft engine TS1400 have single crystal blades. Those are the serial production SCB delivered to TEI.

What you are writing clearly shows that you are stuck like record player on the same thing and don’t seem to understand or don’t want to understand that TEI uses single crystal blades on both TS1400 and T700.
By the way ; I am not you “buddy” !

Okay forum members , I think you know basics about SCBs , thrrr are first generation , then second generation ( with cooling vanes and about 1200°c + temp bearing ) , then thrid gen ( likes of used in ej 200 ,ge 414 with temperature bearing in range of 1450-1750°c ,) coated with ceramic , cooled with vanes and edge cooling ) .

Fourth gen are the likes of used in f135 , 119 ,136 ,136 . Having temperature in range of 2000°c , material used are quite superior , sometimes ceramic based , top notch tech , only usa have it (but won't be hard to develop for any experienced player like RR , etc ) .

Then comes ceramic composite matrix with crramic composite fibres ,with a fixed graim size (used for f xx engine , by modifying f 135 engine , adaptive cycle engine ) ace engine increase temperature in core due to increased airflow on requirements .





.turkey is on second gen , reaching third gen almost , you need to reach 4 gen atleast . And if goal is 5th gen tech ,then get ready to spend 15 +years and 10 billion plus , as except ge no one has accomplished that feat , not European nor japanese , leave alone ruskies .

Are you aware you somehow started to talk about TF engines while trying to talk about TS engines?
Moreover are you aware the T700 is in fact not a Turkish engine but an engine which is origination from a source you have glorified and TEI is producing a portion of it?
We all know where are we at, at least we know we are not on 2nd grade as you have claimed and we all know it takes time, again if you spared sometime and read forum you would happen to realize the engine (TS1400) has a schedule for certification for about 4-5 years while other engines has a longer span + there is a certain amount allocated for R&D.

Imo, just cool down. Take your time, read the forum, see Turkey is not aiming to make F414 next year and make it fly, in fact there is a sound schedule with a sound background prepared by experienced advisors from Tubitak & SSB & TEI.

SCB project dates back, at least, 10 years if i can recall correctly, it did mature 3 years ago and they have jumped to next step already. So there is a track and it is going on.

This is deja-vu, its all been discussed before at length in this thread.

Point is Turkey has the capital machinery, understanding of the process flow and the higher management to handle it.

Results are bearing fruit in the pyramid process to get to apex (as it relates to the big 3 there) at their scale they want to take forward this decade.

i.e all the elements of the ecosystem and there has been debate here already on the timelines and what basis it has.

They have number of advantages and leverages regarding this compared to non-NATO countries....stretching back manner of decades even.

This is not some amateur speculation forum.

Things are not omnipresent to make judgement calls to some extreme to begin with.

Hence this thread and others are to piece together the information and let people reference/debate in relevant way....rather than come in with too much tone either way (fail or success).

Its sometimes best to simply see how it goes...and give benefit of any doubt to people that have participated longer in the debate (if you do not want to read through it yourself).

I don't see your point to throw cold water on this like you are doing here and in TFX thread.

What projects and engines is he not allowed to speak about?

Which engines will go into serial production for which products? That video made me feel good but you know, now I need to know.

PG 50 and PG 115 are two of the three i guess. For Kargi and Herons respectively

Maximum temperatures in a gas turbine are seen in the flame tube of the combustor and then at the turbine inlet. State-of-the- art is about 1800 K which is 1527 degrees Celsius.
If you are working with 1500 degrees Class turbines you are at the top level.
Mitsubishi Heavy Industries managed to achieve 1600 degrees Celsius which was classed as the highest ever in 2011.
It is a fact that the higher the temperature of turbines the more efficient they are. But with it comes the problems.
Yes F135 turbine inlet temperatures reach 1980 degrees Celsius. But just look at the engine troubles they are having. Look at the number of F35 planes waiting for new engines because P&W can’t produce enough blades in time to supply all the problem F135’s.
Same goes for 40+ Boeing Dreamliner planes grounded because RR can’t produce enough blades to fit on to the Trent-1000 engines that work at up to 2200Kelvin (1920 degrees C) .
So too high a temperature is not always good news and it definitely is not a sign of superlative engine. Sustainability of high temperatures on demand is the key.
Russian AL31F has max turbine inlet temperatures of 1472 degrees C.
AL41F has 1642 degrees C maximum turbine inlet temperatures.
Yet these two engines use directionally solidified super alloy turbine blades. OK their engine life cycles are shorter than western counterparts’. So what? They power some of the most formidable fighter planes in the world.
So horses for courses.
We are not aiming for a F135 or F136
If TEI can produce a f110GE132 equivalent with a thrust level of 32-35000lbf , that will suffice. TFX for the time being doesn’t need more. TEI Managing Director has said they can produce this engine in the given timeframe. So the rest of the argument is unnecessary.

I want to know too.
But If I were to guess:
TFX and Hurjet motor developments?
MIUS tf6000 development?
A turbofan engine for Gezgin?
pg50 & Pg115 ?
TF141 with Ukraine?

I am well aware what i am talking about , i am talking about technology of blades and core , i didn't said it's bad ,but i said it won't be good for the thrust requirements for tfx with the advertised range .

And the sound schedule you are talking about is on the optimistic side , companies always do that , the schedule in worst case scenario is never revealed , so chill down .

Delays are part of development , and over optimistic nature never helps .

Over praising some achivement is never good .

Turkey did a good job but now on problems will be much higher and timeline might get a bit .... streched sometimes

Nope mitsubishi engine aren't the top of line .

And issues in delivery timeline are not related to engine quality , don't just type anything for sake of reply .

And ds blades can be good for a certain level of scb but they have tgeir limitations , in scb limitations are present too but at higher temperatures .

And f110 is a older design , non stealth engine , good for thrust but not for stealth

As far as released info goes, MHI engine was classed as the top level in terms of attained temperature in 2011 by themselves and many others at the time. Since then information has been released about higher turbine temperatures which I have acknowledged.
If the engine is not capable of sustaining the lifecycle expected from it with confidence, that engine is not ready. We have the examples of Trent-1000 and F135. It is not an issue of delivery time. RR themselves have said it that due to technical problems and slow production rate of these special blades they have a problem of supply. Not just for new engines but new blades for the faulty engines. All 50 BA and 24 Nippon dreamliners have now been grounded.
Quote:
The company faces 1.6 billion pounds ($2 billion) in extra costs and disruption as a result of the engine problem, which is due to the poor durability of components, and the latest delay spells further frustration for its customers and investors.
Unquote.
A total of 46 F35s are on the ground due to engine problems in the US. More than 15% of the current fleet have engine failures.
No one writes here for sake of reply! Anything written has a significance in the eyes of the writer.
F110 is a tested and reliable engine, albeit old school. The 132 version is the one that the Turkish engine company is working on. After the prototypes TFX will fly with these. Initial few squadrons of planes will be 4++ generation with limited stealth characteristics. At a later stage more powerful and developed engines will be used as indigenous engine technology of TEI improves which will be more akin to stealthy operations. This won’t happen until well in to 2030’s. That is the defined timeline of the project.
We are walking before we start running.
