France hs made fresh efforts to revive plans to develop d Kaveri engine as part of the Rafale offsets deal, Talks were stalled after it emerged that only a part of the offsets jst over Euro250 m could be utilized fr d projects n that DRDO would have had to provide rest Euro500m. pic.twitter.com/eINjHmd3Am

These lines from the deal "GTRE will obtain complete know-how and intellectual property rights for the engine"

Sir What is going on.
Any inside news or guess?
@vstol Jockey
Sir any comment on this recent offer of Safran.
.An acquitance who works on thrust vectoring in one of India's oldest IITs forwarded this to his senior in GTRE and had a discussion on this a few months back and he told me that kaveri is dead for fighter application and they are now only considering it for less demanding applications like drones etc. Don't know if this would change anything even with all the recent developments.
He mentioned that at the moment their primary focus is the certification of micro turbofan for application in cruise missiles. This is a very promising project and they've demonstrated continuous operation of 400kgf thrust engine for 2hrs straight in HAT conditions. This means it'd provide Nirbhay with strike range of more than 1500kms-- much more than Babur!
GTRE's micro turbofan is slightly more powerful than similar Russian turbofan - albeit at the cost of fuel economy. The most promising aspect is it's long range. It'd render India the capability to conduct low level strikes at more than 1500kms. However it's unclear why they're focusing on air launched version of Nirbhay over let's say ship launched. Also surprisingly the air launched nirbhay has an external scoop out intake as compared to in body air takes of land launched nirbhay.
Pakistan on the other hand uses Czech or Chinese derived versions of Czech turbojet engines for babur.
More like 36 more jets and 57 navy jets are linked to engines. The 114 jet deal is linked to MMRCA (I think they are calling it MRFA now).
Complete transfer of know-how and know-why allowing India to be fully autonomous in the future.
This is gold and must be acquired at any cost. If we let this opportunity pass, we are missing out on 10 years of development time again! For Pete's sake, stop playing cheap and grab the golden ticket India!
Agree. Right now bureaucratic hurdles are stopping the deal.
P.S: lol at the genius who had the audacity to click a picture of something titled Confidential and share it to press
Good Day!
Nothing secret in that slide. Probably released with permission to drill it into the aam janta's head the importance of this deal. That slide makes things very clear.
*an indigenous turbofan, that is.

Well, in recent months @delhidefence has gone into the issue of precisely where India stands at the moment with respect to jet engine development. Significant progress has been made in some areas such as TBC etc. I'll return with a set of articles on this issue.

India and the US have ‘suspended’ the ambitious plan to collaborate on jet engine technology under the much-touted DTTI.

“The original project is suspended right now. But we are talking about other potential engine working group items,” https://t.co/p1f2yPc813
Next time Indian delegation should meet them with big buckets bcos US will transfer bucket loads of technology for free. Seems ppl haven't learned any thing from cryogenic technology embargo.
Seems that all the India - XYZ engine technology program are stalling.
I think that in all the case the indian side never want to pay the right price. But it's horribly costing to developp an engine. Probably the most complicated part in a fighter.
GTRE's Kaveri Marine Gas Turbine has been tested to full rated power in the past. That is not a concern. The real concern is with regard to being able to sustain max rated power levels.

They need both 11-15 MW & 20-25 MW class GTs.
— Saurav Jha (@SJha1618) October 31, 2019
For KMGT the real issue was related to the metallurgy of the hot-section and also cooling requirements. I think both of these can be fixed. Because after all, KMGT is basically the Kabini core with an LP spool and PT.

Don't get alerts when tagged for some reason.
Look at the date of the Kaveri article. Its not new. The effort to mount SC blades and re-design the engine has been on for a while. The end result of these efforts is that the Kaveri engine program(with the AB) has been closed. It was concluded that the re-design of the engine will be too extensive and thus very expensive. As such its better to start a new program for an AB turbofan. Work on this has started at an unofficial capacity, it will be announced if and when we stitch up a partnership with a foreign company. Or maybe when we are close to prototyping.
Looks like work on the newer more powerful engine has begun. From DRDO's website :
New Fan
Lab : Gas Turbine Research Establishment (GTRE)
Technology Cluster : Aeronautical Systems (Aero)
The high maneuverability combined with stealth requirements imposes very high inlet pressure distortion at the engine inlet. The fan being the first component in a gas turbine engine is subjected to this high inlet distortion which causes severe surge margin loss. Hence there is a need for a fan development with high distortion tolerance and surge margin. The increased surge margin with higher distortion tolerance would make this standard of fan more versatile for integration with higher thrust class engines. This fan also has anti-icing system.
Prototype of the new fan(stators only) :
