Abstract:
A flywheel formed of a composite material having fibers, oriented substantially in a circumferential direction around the flywheel, embedded in a matrix material. The flywheel having an inner surface, an outer surface, and a thickness therebetween and defining an axis of rotation. A plurality of load masses are distributed circumferentially on the inner surface at a longitudinal segment along the axis. A rotation of the flywheel about the axis with a rotational velocity generating hoop stress in the fibers in the circumferential direction and through-thickness stress is generated in the matrix material in a radial direction. Each load mass produces a force on the inner surface operative to reduce the maximum through-thickness stress in the matrix material as the flywheel rotates about the axis. The rotational velocity otherwise sufficient to produce structural failure of the matrix material produces structural failure of the fibers and not the matrix material.

Claim (Index 12):
The apparatus of  claim 11  wherein:\n each load mass in the first plurality of load masses and the second plurality of load masses has a radial dimension, the radial dimensions of all of the load masses in the first plurality of load masses and the second plurality of load masses is substantially equal to a first radial dimension, \n each load mass in the first plurality of load masses and the second plurality of load masses has a density, the densities of all of the load masses in the first plurality of load masses and the second plurality of load masses is substantially equal to a first density, \n each of the first plurality of load masses and the second plurality of load masses producing a pressure on the inner surface of the flywheel upon rotation of the flywheel at the first velocity substantially equal to a first pressure, \n and further comprising a third plurality of load masses distributed circumferentially around, and coupled to, the inner surface of the flywheel within in the axial stator gap,\n each load mass in the third plurality of load masses having a radial dimension, the radial dimensions of the third plurality of load masses being substantially equal to a second radial dimension less than the first radial dimension, the difference between the first radial dimension and the second radial dimension defining a radial extent of the stator gap within which the at least a portion of the windings is disposed, \n each load mass in the third plurality of load masses having a density, the densities of the third plurality of load masses being substantially equal to a second density greater than the first density, \n the third plurality of load masses producing a pressure on the inner surface of the flywheel upon rotation of the flywheel at the first velocity substantially equal to the first pressure.
