This study identifies design and material choices which optimize the energy storage capacity of a free-spinning, circumferentially wound rim. The rim designs considered were (1) a rim fabricated from a single materials, (2) a rim with lead ballast uniformly distributed along its interior edge, and (3) a rim composed of two concentraically wound materials. The composite rims examined were reinforced with graphite, Kevlar 49, Kevlar 29, S-glass, and E-glass. The rims were required to satisfy weight, size and angular speed limitations which appear appropriate for a hybrid heat engine/flywheel propulsion system. A graphite/epoxy rim with an inner-to-outer-radius ratio of 0.775 was found to have the largest energy storage capacity. (DePo)
