Kaveri Engine

[MonaLazy]

1. From @TejForTweet, RR and DRDO have started the work for 110+KN engine for AMCA.
2. From @KUNALBI25146617, Dassault Systems and GTRE are reviving Kaveri engine LCA.

Here is the big news
India has already started working with Rolls-Royce on engine development. 1) It is a joint partnership. 2) Feasibility study and tech development roadmap is going-on 3) Timeline is one year; post that formal contract signing (maybe)


a-l-r-e-a-d-y started working?

2 different JV is actually a smart move. The one with Safran is for Tejas & smaller GTE for helis/UAVs. With RR the study is for higher thrust engines for AMCA,Tejas Mk2 and TEDBF.For Su30mki, no clear plans yet, reason being without Russian permissions

110kn Engine for AMCA in collaboration with a friendly foreign partner in the next 7-8 years. ~ Dr. Kota Harinarayana

Not if it takes another 2 years to get started (which won't happen before a contract is signed).

First consignment of parts for Kaveri engine
MIDHANI – Mishra Datu Nigam Limited, has announced the dispatch of the first consignment of high temperature alloy for the country’s indigenous ‘Kaveri dry engine program’ powering Unmanned Combat Aerial Vehicle (UCAV).

The supply of the first batch was flagged off by chief engineer of Centre for Military Airworthiness & Certification (CEMILAC) of Defence Research and Development Organisation (DRDO) APVS Prasad in the presence of MIDHANI chairman and managing director Sanjay Kumar Jha recently.

The consignment was containing nickel base superalloy (Superni 263A) and titanium alloy (Titan 31A) forged bars thoroughly qualified in airworthy certification requirements.

These materials go for various class I & class II components of the engine.

The manufacturing of these materials is with 75% indigenous content with the first consignment manufactured and certified successfully in mission mode within 2.5 months, said a press release.

I thought the deal with Safran was dead, or playing dead, i.e endless delays but technically "we are adhering to the rafale offset clause and 'working' with HAL/DRDO to develop kaveri engine"...
So what is this new JV ? Some one please enlighten me

 

[Spitfire9]

Here's our own #India's #DRDO Kaveri engine's variant built with #french #Dassault inputs as per agreement, It's a 1180 kg with 83 KN AF thrust, certification by 2024.

I resume this would be a drop-in fit for Tejas. It would remove potential Tejas Mk1A end user restrictions due to using the F404, wouldn't it? Not a bad thing.

At
@Safran
's brand new factory in #Hyderabad, where the French major produces components for LEAP engines exported across the world and for M88 engines used in #Rafale jets. #MakeInIndia

@Safran
's brand new factory in #Hyderabad

This Hyd facility could make full M88 engines with an adequately large follow up order? :cough: MRFA :cough:

What about DRAL & their facility in Nagpur? What about RR-DRDO? Too many loose threads..

Does it mean mmrca2 Rafale deal is about to be signed? And does it mean that LCA MK1A MWF TEDBF and AMCA will be powered by safran HAL jet engine..

No imo we are looking at another g2g rafale order(given the attempts by certain lobbies to bring out that scam nonsense again).
110kn engine i think will go to RR.they are the only ones who have publicly stated they are ready to give IP so this MOU with safran could be a negotiation tactic by goi.
We will know more during modi boris virtual summit or maybe in person meet later this year

Probably that and help with kaveri....so most likely both

What does RR power these days other than Airbus in the military end?

Typhoon and ofcourse these guys are leading the engine development of tempest project....also they were involved in f136 development

Isn't the EJ200 German engine based mostly based on RR core but kinda dated thats used in Typhoon? Tempest is not in and I would not take anything that involved US company with RR as not a good choice for India due to sanction threat. So that leaves M-88 as the most ideal?

Why not take anything where US company was involved , they co developed engine , RR has experience from that ,not directly transferring that technology here , it's about what have they worked upon , best bet is RR , not safran

Nothing is that easy with US patents, if they want to block they will force their hand. If we do partner with RR then we should do what is mostly RR and does not include GE's ip. I am really not sure what our engineers need and why they are stuck in developing Kaveri,....a lot depends on those details on the type of partnership.

Ge can't hold ip on experience , ip is for direct transfer of technology , and why would they give us what was in ge ip , as workshare is divided , most probably will help with afterburner ,somewhat in hotcore design and other parts , we already have tech for almost 1800 k temperature but can't introduce in kaveri , as require redesigning and a lot of hassles which gtre isn't interested enough and funds are unavailable too .

Also we have experience with higher temperature alloys already , what we are looking for is 2100k + temp inlet probably , same as f 35 engine , that is very much possible , earlier kaveri blades had metallurgy as well as manufacturing problem , also whole body of engine was overweight , we have significant experience now ( not a lot but ) , so weight issue will be solved , also ceramic department is better now , expect it to be a engine as per our specs

That may be the case but f136 is that partnership between GE and RR (every new gen engine leads to tons of ip btw)....problems we are having seems to be fundamental including reliability of components that go into it...otherwise we would not be stuck for so long. Engines take long time, so not a surprise. Why is RR better than M-88 partnership....french premium or english generosity towards India?

No french don't want to make new and give ip to india , what they want is basically a m88 derivative , also no one gives a fuck to attitude towards nation but interest only , rr want cash to be in engine development , with turkey going rogue , tempest being already delayed , US not inviting to any project , no part in fcas project , they want to keep their buisness alive , we can use this opportunity for more arm twisting and getting some tech what we need but safran is in no mood as such .

Kaveri components are old and not every engine part deveolped afterwards are added in it , engine development don't go that ways , we have blades with cooling vents instead of opder Chunk of metal with higher temperature bearing capacity but not used in kaveri as that will require some redesigning (major problem ) , we can achieve m 88 , if we start a fresh design from current technology for a new kaveri we may exceed m 88
