    It's the least risk for them. The Eco core is not part of the Rafale so far, sharing it might even get them the necessary funds to fully develop the ECO and produce parts via DRAL for French needs later.
    At the same time hardly any critical tech share of the Rafale is known so far. So 1 billion offset investment into Kaveri, plays in favour for them, sadly there is no info on integrating it into Rafale so far either.

    IAF was wrong as they mistook the max thrust of M88 core to be same as the thrust rating of Rafale engine.

    The ECO Core is part of the Rafale:
    • It was developed for the M88-9 (M88 able to deliver 9t of thrust but not inducted)
    • It was then used for the M88-4E to improve life of hot and rotating parts.
    M88-4E is the current version of M-88.

    This is what I wanted and more than US, Britain or Russia, I will bet my money on French for being true to their word anyday. They may charge extra but have never let us down. I am more than willing to buy the post of @halloweene where he stated that M88 core has been tested with new materials to temperatures above 2200*F. This means we will have a very lean and mean engine in our stable as our very own.

    DRDO cheif mentioned "new engine" in his quote so might be SAFRAN is also upgrading kaveri engine besides adding their core and this can be the reason that IAF is now not against this deal. So, we can expect thrust of 92Kn

    if SAFRAN guys used this core in Kaveri, then what final thrust can we expect of Kaveri?

    oh...So a 100KN engine can be used in Tejas, no impact on airframe?

    Provided it is drop fit case not requiring changes to the fuselage.

    In that case MK2(S) with twin kaveri engine, would be one beast of a machine.

    The core of the M-88 is studied to allow a Family of Engine going from 7.5 t to 11 t. That is that all these engines will have the same core but not the same compressor and so on. So with this core you can specify what thrust you want and adapt the engine. If you put the M-88 core in the Kavari as it is it will certainly have the Thrust that was initially specified, but you can increase it with changes.

    If you have a core proven for a certain thrust level, all you need is an efficient compressor and fan which can provide that kind of airflow.
