Im designing a flywheel based kinetic energy recovery system for a car. The flywheel needs to have a very high angular velocity to store enough energy. At high angular velocities centrifugal forces will act to pull the flywheel apart, away from the centre of rotation. If i could somehow, maybe by use of tightened bolts going from the rim to the centre axis, apply a force so that when the flywheel is stationary its effectively being crushed. In theory these forces would opposed the centrifugal forces when the flywheel rotates thus allowing the flywheel to rotate at higher speeds without the use of stronger materials.
