It's passed the high altitude test and ready for production.

Aero India 2023: GTRE completes high-altitude testing of Kaveri derivative engine

India's Gas Turbine Research Establishment (GTRE) – an agency under the state-owned Defence Research and Development Organisation (DRDO) – has completed high-altitude...

Pleas understand it did not undergo fly test. It only was tested at high altitude simulated environment (at ground)
Motors (CIAM) in Russia, simulating an altitude of 13,000 m (42,651 ft).

Doesn’t contain any Russian or official source. Not even one.

You asked for a link. I sent you one which is from a neutral source because then you would moan about partiality. Ok here's another one.

It underwent and passed its high altitude simulated test which includes temperature, wind, snow, rain etc. It has flown as well.

You check with your French patrons. They’d certified it about 5 years back for limited flight trials on Tejas.

Nope, they didn’t. What they said was that it can be used, with M88 core. Kaveri as it is was useless.

 

[Akshat]

True, but any progress from these folks, considering their usual shenanigans, is still massive.

If there is an actual development, then yes, it’s a big deal. But there is nothing new happening here. This has happened in the past and we have seen the results.

Still no comment from Russia. I said show me a single link where anyone has said on record that Russia has certified the engine. Even DRDO never claims that because they know it’s a lie. They only give unnamed sources. Show me something with a name. Someone who is ready to say it on record.

 

[Squarecut Atul]

Too little too late kind of development. All these news that are proudly displayed here tell a sad tale of missed opportunities. These are works that should have been done four decades ago.

 

[Pramkumar]

To export Tejas Series Kaveri engine and indigenous Avionics, Radome, ejection Seats are important.

 

[Partha Sarathi Dey]

USA will kill this programme by hook or crook. All those human rights, Democracy index, cast & religious discrimination allegations, Sikh for Justice actually tools of deep State of USA to achieve this goal. They want us dependent on them for ever. Our Political class is hand in glove with them

I highly doubt that. The Kaveri has a dry thrust of 45-48 kN. Taking that to 73 kN on wet thrust translates to roughly a 60% increase in thrust using an afterburner.

However, reaching 90 kN would mean 87.5-100% increase in thrust using an afterburner. From memory, there is not a single engine that has ever achieved this feat. The highest thrust increases generally come in at 70% or so, unless you look at some Russian engines that can do 80% extra thrust on the emergency thrust setting, but that tends to ruin the engine. 90 kN may simply not be possible using just an improved afterburner. The core may need to be altered.

F404 has dry thrust 48kn and afterburner 84kn. That is 75 percent increase. Looks 🙈 like they need to increase dry thrust.

 

[Boomeranger]

Read the article again. It mentions the possibility of substituting a 90 kN derivative on the Tejas. That said, it could, atleast in theory, be used on the HLFT-42 as well, but we shall see.

Another 30 years later only 90KN engine will come out of GTRE. Dey r 100% SAME as HAL only talks to boost equity in markets.

Yes you asked for a link I provided you with two so just stop making excuses and feeling embarrassed that you were WRONG and that the engine passed its test in Russia’s.

None of which provided any source. So stop arguing and show proof. You are the one who has been humiliated here. The engine is useless and hasn’t passed anything.

Jane’s is an independent source that’s very well respected in the defence community with accurate information. If your so desperate I’m sure you can find what you want on Google but I’m not wasting my time finding something that I’ve already found and shown.

So you accept that Russia has never certified Kaveri. Good that you accepted your lies. Exposed.

Kaveri Engine Update: Clarifying Misinformation on Safran Clearance​

Recent reports circulating about French company Safran clearing the Kaveri engine for immediate integration with India's LCA Tejas fighter jet have been clarified as misleading and based on outdated information.

Sources within DRDO confirmed that while the Kaveri engine project is indeed undergoing a revival, Safran's involvement is not new and stems from a 2018 audit conducted as part of offset obligations related to India's purchase of Rafale fighter jets. The audit concluded that the engine was ready for limited flight testing, but there are currently no plans for Safran's formal participation in the project.

The DRDO has outlined an independent development roadmap for the Kaveri engine, with plans to test a dry engine with an afterburner on an LCA Tejas trainer aircraft by 2028-29. This timeline aligns with the organization's commitment to achieving self-reliance in critical defense technologies.

While the exact future of the Kaveri engine remains uncertain, the DRDO's progress and determination to continue its development offer a promising outlook for India's indigenous fighter jet program.

Nice if DRDO do it alone by 2028-29 with 90 kN Thrust & Reduction in weight below 1000 kg appx 950 kg. 97 Tejas MK1A order will b placed

 

[wallisk]

BEST option now is to approach Russia for Sea Wasp RD33-MK3-OVT engines make in India by HAL Khoraput - same as the previous SeriesIII engines deal terms and conditions... Then ADA can design a NO canards TEF MK3 Tejas jet using these engines..

drdo gets confident only after safran auditing in 2018.

We already make this engine in India as part of MIG-29K maintenance, this engine is going to replace the old RD-33 engine in MIG-29’s as part of UPG upgrade, this engine is a bigger engine compared to F414 in size but produce very little thrust.

DRDO can’t do it even by 2098-2099

 

[Akshat]

The Safran audit was nothing to be confident about. In fact the program was shut down after that and dry Kaveri launched. The audit said that the entire hot section is useless and Kaveri can only be used in LCA with M88’s hot core.

 

[Sudha]

Do not bet & lose money on it. Involving Bharat's private sector will make the engine ready for mk1a by 2030.

90 kN thrust isn't happening, atleast not with the present core. The present core allows a dry thrust of 45-50 kN. With that, assuming you want decent maintenance, reliability and fuel efficiency, we would be looking at 75-80 kN of wet thrust or thereabouts. With some changes, we could possibly get it to 85-ish kN. Anything beyond that would require a reworked core.

They said give GTRE a flying test bed. No need for Safran.

 

[ramdas]

Thank @Raghav Patel for the detailed clarification provided. The success we were all anticipating has generated a significant amount of enthusiasm among everyone involved.

NATO disinformation campaign seems to be working.

 

[Harsh]

Any exactly why does India need to clear certification for an India made engine to mated with India made jet? Are we so gullible that we fall for every "news predator" that needs to amuse (or irritate) us?

The comment I replied to specifically said ‘DRDO do it alone’.

And DRDO messes up even when paired with private sector. Look at ATAGS or WHAP for example.
