Mirage200 and LCA intakes are not really same. The former has an adjustable nose cone which increases the efficiency of air intakes. It can be seen in its picture.

It is not just RPM. Any change in RPM will magnify the centrifugal force to the power of 2. Even mass and radius of a jet engine is way higher in case of jet engine. So higher mass, RPM and radius will magnify the centrifugal force / area. It must be like a single blade in a jet engine will...

As far as i recall, the issue lied with manufacturing single crystal blades for the engine. Making it in a lab is one thing, installing /importing / manufacturing machinery to manufacture those blades for production is different. Another reason being kaveri was not just underpowered, but a...
