Kaveri Engine: Latest Developments & Discussion

[Kunung]

Why can't they use this engine for SEPECAT Jaguar. That jet's engine thrust is significantly lower than Kaveri engine. They can use Kaveri if they can improve reliability.

 

[Sudha]

From the initial stage itself it should have been a joint private public sector effort. In fact to increase the output it seems the private sector has contributed the tech. GTRE & DRDO personnel are government units after all just making sure of their salaries without any hyper interest in performqnce.

learn from chineesh and Turks. Turks Khaan fighter to get a engine which is lower than the HTFE40

Kuch bhi? Kaan is using F110 which has ~75 kN dry thrust. It has 130 kN of wet thrust. And it is using 2 of them. And HTFE produces 25 kN dry thrust. So kuch to dekh ke bol.

 

[Akshat]

Good, but the million dollar question is - when?

How dare you to ask DRDO for a timeframe?

 

[Pink Panther]

Eh, getting the engine up to 90 kN would require, in essence, a new core. The present core can probably just about reach 75-ish kN wet thrust, which is what they are targeting. Getting 90 kN wet thrust would need around 55 kN dry thrust, which isn't happening with the present core.

We will be working with RR on either EJ200 CORE or something linked to it for Kaveri very soon.

RR doesn't have the core tech itself 🤣🤣It imports it from France.

What nonsense! The Kaan's engine is the F110, the same base model as that used in the F-16. From memory, the two engines on the Kaan have a combined wet thrust of over 250 kN. Even with the planned new engine we have, two engines would give some 230-ish kN.

France's 😭😭😭 WW II era Core tech, we are not interested, only advanced tech like EJ200 from RR and MTU or GE or Pratt & Whitney.

No they don't.

RR along with GE, P&W is leader of jet engine technology. They have 2nd biggest share in civil market. RR & GE were runner up for F36 engine with their F 136.

Turkey wants their help to develop Kaan engine. Japan almost signed contract to develop engine with their assistance befor joining Tempest.

RR assembles full engine in their factory with only forging done before, that too not in UK. UK is self sufficient in jet engine technology due to RR being among pioneers

 

[Aloo]

RCMA is a DRDO lab. So you have just proven my point that DRDO is the only one who is saying that this engine works.

Shall we admit now that you are just a DRDO apologist spreading misinformation?

Their word is to be accepted as RCMA is the certification agency. It involves scientific process with test data, cannot be just ignored. Need substantial proof or a new audit to deny that.

CAG report of DRDO lying would be invalid coz generic. It will be applicable if it specifically calls RCMA certification of Kaveri false.

Mr. genius, RCMA is entrusted with certification, which comes under MoD which comes under GOI. What else do you expect, get a fcking nobody commenter from internet to do the certifications ? You have the RTI act, if they are faking, you have the right to question. You have the right to cross check their data, expose them & take them to court. Our democracy gives you that right. That is if you are an Indian citizen. If you are a Paki/Chini pysops agent, obviously you cant do that. You asked for officials, you have been the given the officials. what are you going to do ? Nothing. you have no credibility. Why dont you go watch cricket, fap, drink beer and call it a day ?

I think you need to update your facts buddy.

In the F136 program, RR was giving their LiftSystem, which was required for vertical take off. The actual engine had little contribution from RR UK. RR's share was only 40%.

In the Eurojet consortium also, RR had a share of 33%, which increased to about 44% when they later acquired a company from Italy. So the ~40% number is consistent.

In fact, if you look at even the Adour engines, the compressors are imported from France.As of now, or even in the last few decades, there is not a single engine which was entirely developed by RR (talking about operational fighter jet engines). UK is anything but self sufficient in engine technology.

Well we Indians clearly are interested. Don't know about you. That's why our P M included it in his joint statement.

 

[Avesh]

Yes on RR and GE, we stopped looking at WW2 Tech, not interested anymore.

 

[Fresh Water]

Building a test platform would expedite many other possibilities.
Many of those possibilities are beyond most of us at the moment.

Build the facility, and also let the private sector use it to test their innovations.

 

[Blademaster]

but the thrust to weight ratio is less than the GE-414 or the proposed Kaveri engine.

In a major boost for India's self-reliance in defence technology, the DRDO has achieved a substantial weight reduction in the Kaveri derivative jet engine.

The current combined weight of the engine and afterburner stands at approximately 1180 kg, down from 1235 kg and considerably less than the initial prototypes which weighed over 1400 kg. This remarkable reduction can be attributed to several key factors:

• New Fan Module: A newly developed, lighter, and more efficient fan module has significantly contributed to the overall weight savings.
• Core Changes: Extensive modifications and optimizations in the engine core have addressed previously over-engineered sections, resulting in further weight reduction and potential performance enhancements.
• Afterburner Module: The afterburner section has also undergone substantial weight reduction, shedding 70-90 kg while maintaining its functionality and efficiency.
• Material Validation: The use of newer, lighter materials, rigorously tested and validated, has been instrumental in achieving the desired weight reduction.

The DRDO aims to further reduce the weight of the Kaveri derivative engine, without the afterburner, to under 1 ton. Once all new components have been thoroughly tested and integrated, the final weight will be determined.

The next crucial step involves integrating the engine with the LCA Tejas fighter aircraft for comprehensive testing. This phase will validate the engine's performance, reliability, and suitability for real-world combat scenarios.

The successful development of a lightweight, high-performance indigenous jet engine is a significant step towards India's self-reliance in defense technology. The Kaveri engine's reduced weight will enhance the LCA Tejas's overall performance, maneuverability, and range, making it a more formidable combat aircraft.

 

[sanket]

Great News. weight reduction & Thrust enhancement will make Tejas MK1A poweing Indigenous Jet Engine

 

[shivkumar sinha]

Well done DRDO. Development of Kaveri engine in parallel with new AMCA engine with foreign collaboration is necessary .More funding and political push should be provided to kaveri project .

 

[Pramkumar]

From 1400 to 1180 is good development
IAF should work around kaveri engine other wise we will hear the stories of HF marut only

 

[Vineet Sharma]

Weight reduction.. This means everything with this engine is going fine and people involved in engine design are understanding the principles behind the machines.. Great work.. Hope to see a new engine soon with another thrust class.. May be of 110KN

 

[bonito]

Dissociate Ghatak from Kaveri engine. China is preparing for war. We cannot afford to lose focus on Ghatak for the sake of Kaveri engine.

 

[Ranjeet Singh]

Ink deal with Safran to make 90-95 KN Kaveri engines for Tejas-1A, and also make Tejas-1B powered by Kaveri (95KN ) engine and air frame like Mirage-2000-9 can attain Mac 2.25 speed !

 

[NSR]

"Next critical step will be the integration of the Kaveri Derivative Engine into LCA Tejas for testing purposes"

Holy dear God, no, next step will be using Russian or may be French high altitude test bed to test extensively for all performance parameters in at all elevations, etc
Only when it meets the vibration, performance, start on and turn off at all altitudes, quality of components, reliability of components, etc then GTRE can put it in a real LCA/Tejas fighter and test it with a real pilot.
Not even a second before those things are tested completely.

India must remember that a fighter test pilot life is not CHEAP one to put in HARMS WAY.

 

[Pad UwU]

This would be good for drones but not for jet fighter, because it's a new engine without enough extensive flight stress especially in training, dog fighting and war😺

Sadly we suck at anything related to Silicon, and it's this very element which dominates the current engine manufacturing process.

As far as I know, the Kaveri's earlier iterations were using Nickel Superalloys. Maybe we are progressing towards Silicon Carbide now, but what we need to do with 110 kN, is to take the leap of faith and go for Carbon Fibre Composites.

What well done? It’s just another one of their plans. Nothing actually achieved on the ground. So well done just for the thought of doing it?

U have no other option than to make your own engine . Steal , borrow or do whatever but make it work. U can't trust on French , British or anyone for that matter .

 

[kumar]

Step in the right direction. Jet engine development is done iteratively. There are no shortcuts here.
But for God's sake plz establish engine test facilities in India. We cant keep going to Russia or any other country for that matter. It will only kill valuable time. Flying Test bed and high altitude test facilities are a must.

Agree with that. But it’s not gonna happen with GTRE in charge
