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.
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.
Exclusive Updates From The HAL Tejas Mk1 & Mk1A Programmes
1. Efforts underway to rectify design flaw in Kaveri.
2. Efforts are also underway to put SCB blades in Kaveri.

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) :
