    Sorry for the noob question -
    Will increasing the thrust with the same core means more wear and tear and less life for the engine??

    not at all. If the airflow is correctly maintained and with proper compression, If you go thru the equation for jet engine thrust, you will realise that mass flow is the determining factor. A core must be able to withstand that kind of temperatures which are associated with such gas expansion.

    Just the way you will have a candle blowing off with too much of air or fails to burn with very little air, same is true for core of a jet engine also. A core cleared for 11ton thrust means, that it can withstand temperatures associated with air flow required to generate such thrust.

    No it depend on what you change, for example to increase the thrust to 9 t for the UAE (it was not done) we developped a demonstrator M88-9 and for that we change the air mass flow from 65kg /s to 72 kg/s this modification doesn't change fiability and availability and general characteristics of M-88. But it change air inlet of Rafale so aerodynamic and RCS and then it cost to change the plane!
    Now we have a new project of a M-88 8.3 t of thrust without changing the air mass flow. It doesn't change the plane, fine, but normally it change temperature pression and other parameters of the M-88 so normally it change the availability and fiability of the Engine! To maintain these qualities you need to improve technology, and it's because we have improved technology that it is now being considered to make this new version of M-88.

    No new core from scratch is in development.
    Out of 4 Prototypes which are being prepared by SAFRAN and Kaveri 2 have kabini core and other two may have M88 core .
