Flywheels are used in applications where the power stroke is not constant, like in an internal combustion engine which only produces power for 1/2 of one stroke for every 2 cycles per cylinder. The moment of inertia is kept high so that once the flywheel is turning, it keeps the crankshaft turning when there is no power applied to it.
Jet engines produce constant power - they continually feed fuel and air into the combustion chamber - so there is no need for a flywheel.

are you high, or do you just not know how to ask a question?
flywheels are designed to have a high moment of inertia.. thats the point of a flywheel.. th increase the moment of inertia of a system.

So that it's rotational velocity will remain relatively constant. After all, that's the reason it's there in the first place âº
