Next generation engine for 6th generation Aircrafts and UCAVs

Bdw saurav jha is saying a new engine is in development.,
..and he will share later

I think he wants to mention the journey

Kaveri should go variable cycle mode.

Kaveri engine project is dead.

Yeah, at the moment it is very much likely, but these are strategic matters so there might be a little bit of secrecy and Kaveri without its afterburner has enough thrust to power ucaf. A French offset is also there.

Kaveri is unable to generate enough thrust for thrust...but it still can be used with drones....I am talking about ucav ghatak
And we are developing a 110kn engine (hints saurav jha)...though not official

When it is clearly stated that AMCA needs 110kN and MWF needs 110kN, it is quite clear that we are developing 110kN engine. Also, Kaveri has 52/81 kN thrust. This is good enough for Tejas with slightly lower payload. It can also be used for Rafales made in India

Kaveri is dead but its spirit is alive in 110kn program.

India can now quickly build bigger jets, says DRDO chief

After the final operational clearance (FOC) of Light Combat Aircraft Tejas, India is now looking at a rapid multi-pronged effort to build the next class of fighter jets having more powerful engines and potent weaponry.

Dr G Satheesh Reddy, who is Secretary, Defence Research and Development, and also Chairman of DRDO, said, “The FOC for Tejas is a landmark for the country. From here on, we can produce faster (jets).” The design for the Medium Weight Fighter (MWF) is ready. The prototype will be ready by 2021-end,” the senior defence scientist added.

The Tejas weighs 6.5 tonnes and the MWF is the next class and targeted to weigh around 17 tonnes. The Aeronautical Development Agency and the Indian Air Force (IAF) have designed it as per the requirement of the IAF. It will have an engine of 98 Kilonewton (Kn) thrust.

Also, India is looking to take a technological leap. The DRDO is now in talks with an international partner to make a jet engine of 110 Kn power. So far, no such engine exists anywhere in the world. “We are open to working on this and are in talks with partners for joint development,” said Dr Reddy, adding this engine could be used on future jets.

On being asked about the Kaveri engine, Dr Reddy said it would be used on UAVs. “It is not being shelved.” Notably, Kaveri’s thrust is about 75 Kn and 90 Kn is desired to power a fighter jet.

The Ministry of Defence has already informed Parliament about the technological difficulties of engine-making, including non-availability of raw material/critical components and skilled manpower.

On the much-debated construction timeline for the variants of Tejas, Dr Reddy, who took over as DRDO Chairman in August last year, said the first 20 of the Initial Operational Clearance (IOC) version will be ending very soon. The production of 20 jets under the FOC version would start this year and would be done in two years. We are waiting for the IAF to place an order for 83 jets of the Mark 1A version.

On the engine of the Arjun tank, so far imported from MTU Germany, Dr Reddy said, “A new engine is being developed and will be tested.”

Kaveri will be used instead of M88 in Rafale as and when Rafales will be made in India. Kaveri is very much alive

not likely at all in many ways...

e.g. althouth it seems in the same thrust class, M88-2 is such a light machine which weights around 900 kg with the 8.5:1 T/W ratio

M88 is 900 kg while Kaveri is similar to F404 (1040kg for 81kN thrust). The small difference in engine weight can be ignored for 2 reason:

1. M88 has rhenium which is very rare and difficult to obtain in case needed for urgent mass manufacturing
2. Indigenisation and its benefits far outweigh some performance degradation

Kaveri weight is 1250kgs almost 350+kg more

We are not going to degrade performance of our prime asset. It's too costly to do such a thing.
Also rafale will need all the thrust it can for further upgrade mid life. A heavier engine will make mid life upgrade much more difficult.

Another possibility is if French cooperation can help reduce Kaveri weight to 900-950 kg with 76kn thrust then maybe your idea could be feasible.
But still installing a new engine will require 5-6 years of rigourous testing. We don't have time for that with rafale.
