How does indian aerospace compares to Tei in terms of jet engine development. Where do you think they have difference? For example: combustion chamber, blades or sth else?

If we compare it, TEI is superior. I believe they are almost 30 years busy with the program so people who are talking bad about TEI should think twice what kind tecnology we are dealing with.

HTFE-25 program is less than 10 years old. You are thinking of Kaveri.

ther was a engine program for ther fighter and still are they working on that. Maybe it was that Kaveri, it was 5 years ago when i read about ther engine program.

Given the parts that are manufactured for variety of engines that TEI provides, i know that for sure TEI is one of the largest in aerospace jet engine subcontractor.
I believe Mr Aksit when he said that TEI is 5th company that became a western type jet engines with ts1400. Hope that we ll prove it further once tf6000 became operational.

Dr Aksit is definItely a brain and asset this country has produced that needs to be respected. But he does like to blow his own trumpet a bit too much at times, and whilst doing that exaggerates to a certain degree. There are engine producers like GE, P&W, RR and Safran that are in a league of their own. There is also CFM ( a conglomerate of GE and Safran) that specialises in passenger plane engine manufacturing.
Another top player is MTU Aeroengines of Germany (wholly owned by Kohlberg Kravis Robert’s) that produces complete engines as well as parts for P&W, GE and CFM. MTU, produces engines like EJ200, F110, F414, LM500 etc. as well as being a growth partner of engines like PW4000 engine, that power Boeing 747-400 and Airbus A300.
In the East, IHI of Japan works very similar to TEI. But is far ahead of us as they can produce complete turbofan engines like XF5 and XF9 engines.
These make 7 top manufacturers of western built jet engines. We are not there yet. When our TF6000 starts to fly, and our indigenous MMU engine materialises, then we may think about taking 8th position at best.

I am not gonna argue with Big 4 in Aero engine business but Also MTU does not have any modern aero engine design they fully own its IPs. They are huge subcontractor but Not an Engine designer.

CFM is also joint venture among big 4 in order to increase their profit rather than compete with each others in its field. It wont enter another field of aero engine business unless its parent companies decides. So Neither of these 2 companies is or will be competing for aero engine business in general sense.

Yes, IHI is ahead of TEI and it is that simple. But that doesn't mean TEI isn't fighting for the 5th position.

It won't stop there, when you have the Özgün engine of TFX as an achievement under your belt you can go for civilian turbofans. The size of the TFX engine allows the development of a high bypass turbofan engine that can power a twin engine passenger plane of up to 300 seat capacity. While Japan and Germany can not ask for more than they already have the market Türkiye can address allows for such a civilian engine to be developed. Number 5 position is surely possible.

Don’t underestimate MTU Aero engines. They work similar to TEI bu are in fact ahead of TEI with their set up. They have been manufacturing jet engines and parts for much longer than TEI. They do design, develop and produce aero engines in conjunction with companies like P&W and GE for commercial passenger planes and gas turbines.
To be honest unless you are one of the big 4 ( CFM, GE, P&W and RR) you have no chance of producing engines for passenger jets. For military planes, MTU already manufactures most of the EJ200 engine anyway.

Yes CFM is a conglomerate set up by GE and Safran. But they do operate as a separate entity. They are the largest jet engine manufacturers today. They have subcontractors like TEI, MTU and IHI.
We will get there in the end. But it will take a bit more time. I don’t know about 5th position. But in terms of military jet engine manufacturers may be 6th or 7th ( GE, P&W, RR, Safran, IHI, MTU) . We can’t even manufacture a turbofan yet. Even Motor Sich of Ukraine with their outdated technology were ahead of TEI in terms of complete engine manufacturing capability. We had to buy engines from them for our helicopters and UCAVs.
You don’t become one of the top 5 jet engine manufacturers in the world, just because you managed to produce a non flying but operating turbo shaft engine. TEI has not manufactured any engines that fly, apart from the F16 turbofans and Atak t-129 and T700 Blackhawk tuboshaft engines in house.
As I have said; A bit more patience. Let’s see TS-1400 and TF-6000 flying ; Also MMU indigenous engine become a reality. Then we can discuss if we are as good as IHI. We have the basis to become a contender. But let us walk before we run with our grading.

There is no point in simply putting today's situation while the potential Türkiye can realize is far more. It will only take some extended sanction madness coupled with a new partitioning of global political landscape to jump leagues and get there.

There are big 3;
GE, P&W, RR
Then comes French Safran and Japanese IHI
Rest it similar. TEI slowly climbs up the ladder with its own designs. There is no way to catch the top 3 unless you jump the train of a paradigm-changing technology like composite turbine blades early on. The US companies are moving to adaptive cycle engines, and RR is tasked to develop the engine of Tempest. If we can successfully develop the engine of TFX we can consider ourselves more or less at the level of Safran and IHI.

TEI has to build its own turbojet engine first .. till now its a supplier

We should expect an engine with comparable performance to LM500. But I doubt it since even the small LM500 is based on a larger airliner engine. Maybe they will use it in a dual configuration who wonders..

Edit: Looked up on LM500, its based on CF34 which has 8000lbs thrust. We can expect further versions of TF6000 to be similar with it.
LM500 suits to FACs not frigates or destroyers. LM2500,LM500 all relies on the same core* with additions but i am not an airliner guy so @Nilgiri may explain differences on how they attain a larger shaft output (all that matters on a ship) by adding new disks.

*LM2500 based on CF6
*LM500 based on CF34
