Re Arun
My layman understanding is that if we use a 10-15% more powerful engine the fuel consumption will also go up by 5-15% even if we dont use the full power because deceasing thrust while flying does not decrease fuel consumption of turbines in same proportion as the SFC goes up. On the other hand LCA contemplated Kaveri while GE might be more fuel efficient engine??).
But inspite thereof, ii seems from Subramanium PD-ADA commnents that they are NOT contemplating major (or even any) changes to fuselage, wing etc compared to comments of HAL or PRajkumar. I think that they-ADA will put in a powerful engine with change of intakes and take it up from there. Perhaps that is why we have not seen any diagrammatics of changed LCA Mark-2 because there ain't any.
If any serious changes were contemplated then Naval LCA which started its life in 2003 may have also been changed.
