Pretty good then. It's no different from any western 4th gen engine. Only short of engines like M88 and EJ200.
Midhani is now upgrading these with more exotic materials which they have just recently developed and new thermal coating will improve it further.
No doubt that Rolls Royce, snecma, are making noise that they are ready to transfer engine technology to India. They know by 2030 india will be self sufficient in engine technology, in at least what they have now. Future advent type engine technology with 2350 degrees c TET will be a generation ahead of what we will have by then. But even with ej200, ge414, snecma m88 level of technology we should not have any problem by then....
I'll be really happy if we achieve temperatures above 1800deg C by 2030 on operational designs. That will put us on par with the latest Russian engine.
But at least current technology allows us to make forays into gas turbines for power generation as well as powering ships and such.
Seeing any effort on that ? I was so disappointed when news from the Kaveri Marine engine died down. Is the project closed ?
Nothing's closed. They are moving into uncharted territory, so they are being overly cautious. New class of frigates beyond Nilgiri class have to be designed for marine Kaveri to be used. So let's hope the next batch of frigates will carry it.
Also, new gen frigates and destroyers will need power between 15 to 30MW for each engine, but Kaveri is at 12MW, so it has to be upgraded. So this is a problem, the same thing that's facing LCA.

All problems of Kaveri has been resolved. Now it is developing 81 kn of wet thrust but not able to sustained it for longer duration. Means work on Kaveri is continued. (There are rumours of a new version of Kaveri is being in working by putting SCB in HPT and newer materials including DS blades in LPT. MIDHANI is experimenting with DSM 4 by mixing Ru in it with excellent results.)

Hard facts right there. We do not have the kind of manpower, the infrastructure to test and develop the Jet engine on a industrial scale. https://t.co/JJzs3MR1vn
THREAD!!
This is such a storm in a teacup
Yes it's true that India lacks flying test beds but this really isn't as big of a deal as some would like us to believe.
FTBs have been lacking in the past but when required have emerged- HAL has multiple FTBs for testing of SARs, EO payloads, transponders, SATCOMs etc etc.
When Kaveri is ready to be flight tested it will be- the platform will come.
Look at UTTAM- they moved from a ground test centre to a helicopter now to a biz jet FTB and a LCA LSP.
Kaveri's new fan. To be used for the engine's dry version used on the AURA/GHATAK UCAV :
Look at those long chord blades. Beautiful.
Long time no see. You were missed. Both you @Aashish seem to operate in packs. Either you're prolific together or MIA together.
MIDHANI has successfully fabricated high-pressure discs for the compressor section of the Adour MK 811 low-bypass turbofan that powers the IAF's Jaguar fighter-bombers. A noteworthy example of import substitution in the materials arena.

Anyway, @DRDO_India's GTRE has taken up the development of a non-afterburning version Kaveri engine (IUCAV-UHF20) for a sanctioned cost of Rs.1068.69 crores.

👉SX turbine blades and vanes are produced by using an orthogonal grain selector from advanced Ni‐base superalloys.
👉Ceramic silica cores are used to get hollow cast components
👉Intricate cooling channels are possible
👉DS and SX components can operate at higher temperatures
