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 7):
The apparatus of  claim 4 , wherein each load mass in each of the first plurality of load masses and the second plurality of load masses is formed of a permanent magnetic material and has a magnetic polarity, the magnetic polarities of the load masses in each of the first plurality of load masses and the second plurality of load masses alternating circumferentially around the flywheel, each load mass in the first plurality of load masses being disposed in axial alignment with, and having its magnetic polarity oriented in the same direction as, a corresponding load mass in the second plurality of load masses, the first plurality of load masses being axially spaced from the second plurality of load masses to define an axial stator gap therebetween having a longitudinal gap length, and further comprising a stator having a plurality of conductive windings disposed thereon, and having an axial thickness less than the longitudinal gap length, the stator being disposed in operative relationship to the flywheel such that at least a portion of the windings are disposed axially between the first plurality of load masses and the second plurality of load masses in the stator gap such that rotation of the flywheel relative to the stator produces a flow of electrical current in the windings.
