GTRE Kaveri Engine

so basically whatever we have developed is of no use and still we have not aborted our dream to develop a fighter jet engine so we will be starting from scratch, 15 years from now some engine will be there again to talk about.

15 years, 20 years, who knows?

Kaveri in dry thrust version will be used though. So GTRE's main focus will be to improve Kaveri's dry thrust.

For fighter jets, we need an engine with foreign cooperation by 2027 for AMCA, and perhaps our own indigenous engine after 2035 for future aircraft.

What abut the Kaveri marine gas turbine engine, people. What happened to it ? I was so happy when I heard the navy is pushing ahead with this and then everything just went quiet. Is that still on or what ?

We definitely need some help to make it work.Motor Sich one of Ukraine’s turbojet manufacturing companies may have some brilliant mind and we should try to use them like we did for ISRO semi cryogenic engine.It may be a cheaper option just a thought.

The Kaveri K-9 has reached a dead end. There were certain fundamental problems discovered by SAFRAN which entailed redesign of the core if GTRE wanted a thrust of 98 KN & above. This wasn't feasible at this late stage.


As the 2nd video speculates, the K-9 would probably find it's way into the UCAV program apart from other ones. Plans are on for the K-10 for which RFP have been requested by GTRE / DRDO. All the learnings from the previous prototypes would find it's way into creating a new core and the K-10.

@vstol Jockey ; @randomradio Perhaps you'd like to contribute.

I don't have much expectation left from the Kaveri, at least in its present form. No news, good or bad, comes out of it anymore. But then every now and then I come across research papers like this one here that makes me believe things are still moving along, slowly as it maybe.

It is titled "Synthesis and Application of Nano-structured Bi-layer YSZ-LZ Thermal Barrier Coating"

It contains a treasure trove of information about powder metallurgy, sinter agglomeration, micro-structure of synthetic metals, properties of said metals etc. Every step of the process uses some kind of an exotic metal that I've never heard of in my life and the end result creates conditions that are neither easy to comprehend nor easy to explain.

In other words, this is well beyond my ability of comprehending. I'd request the resident experts to please do their bit to enlighten us. @vstol Jockey @Falcon @randomradio @Ashwin @_Anonymous_ @Parthu et al.

In the picture above, the white flap on the left and the one on the right are with the new coating. Where as the two in the middle with dis-coloured coating are the old ones. Wonder what engines they used to test this.

Here you can see the active involvement of HAL Koratpur facility for doing all the testing. Koratpur facility makes the AL-31FP engines for the Sukhoi Su-30MKI from ground up that is from raw materials stage. So maybe a AL-31FP engine was used for testing.

For the Kaveri, it's at a standstill, the Indians are not making any progress on this project. Safran's propal remains in the pipes, but they're not doing anything about it yet.
My opinion is that they are doing as usual in India? They are so afraid of making a bad decision or getting swollen that they are kissing the *censored* of all the other Western manufacturers to wait for a better possible proposal. In the meantime, without a national engine, the Tejas risks abandonment altogether, and uncertainties about the Tejas make the new engine uncertain. In short, a vicious circle and a snake biting its tail.

@Picdelamirand-oil, @halloweene, what is the latest update on Kaveri other than what has been posted above.

I think Tejas is dead and the Indian aeronautics industry with, at least for the next twenty years, that everyone knows it but that nobody accepts it in your country.
In the long run, you will have no choice. It is EITHER the construction of a stable industrial base, OR an increase in squadron capacity through off-the-shelf purchases.
But both in the short term, it's just impossible. If you want to keep your IAF re-equipment, you'll have to buy off the shelf, build and assemble under license, and acquire the skills that will allow you to relaunch a national program later. But here, the Tejas as an aircraft is very largely obsolete. It's a pity because the Kaveri would have had a good potential, possibly on a twin engine.
