Is India's 110kn turbofan engine for amca be a verson of item 30? Just a naive thought....
India's 110kn turbofan engine is supposedly developed based on Kaveri, a 3rd generation engine while item 30 is a genuine 4th generation engine.

Any other specification other than 110 kn of India's turbofan engine like thrust to weight ratio, engine dimension, material to be used etc etc...

Why can't Kaveri K9 not be used in our naval twin engine fighter? Rafale uses M88 with max of 75KN and our Kaveri being fadec can be software tuned to a max of 75KN. It has a problem with sustaining high thrust at 81KN anyway. We could have a medium weight naval fighter. Why no thought is provided for those?

You are right, but weight of M88 is 900Kg and that of Kaveri is close to 1250Kg. But still I think that we can give it a try, atleast from shore based platform and later when proven can be stationed on AC. Atleast get some data for further improvements and research.

Because you can't put a new engine on a naval fighter before it accumulated enough data and experiences in land based fighter, the ocean environment put far bigger challenge to jet engine than the land.

India's 110 kn is not developed yet how can you say that it is a 3rd gen engine ?
Kindly describe other specification of this engine like dry weight , thrust to weight ratio , turbine inlet temperature , length , diameter etc.

Rafale M was manufactured first and then Air Force variant of Rafale. So in this case M88 was first tested on Rafale M if I am right. Wiki says the same info.
It's not much, but without testing we will never know.

If india devolops it's own 110 kn engine,it will be a clean sheet design...drdo boss himself stated in an interview that drdo moved forward from kaveri,they now see the kaveri project as a tech. demonstrater..

For testing turbofan engine like kaberi we need a flying testbed aircraft, without testing its flight-worthyness and maturity on the same for sufficient data collection and analysis you can't just put an engine on a new aircraft. In india if crashes occured in a developing aircraft then whole program would be in jeopardy.

The engine should be reliable , Kaveris performance is very unstable .

Dry verson of kaberi to power ucav is developing, when matured it will provide the basis for a new engine development. At the same time India should perfect high end matallurgy for engine manufacturing.
