Based on application, geometric and material design constraints, the single-material or multimaterial multi-ring rotor using either a metallic or SMC hub were judged as the most promising flywheel design concepts. This analysis centers on the stress patterns, working stress levels, rotor weight and geometry and material cost of possible flywheel designs. Physical sizing, maximum operating speeds and rotor weight are based on a 1.0 Kw-Hr usable energy storage with a 2:1 speed range. Various combinations of materials and stacking sequence give rise to a flywheel data base consisting of fifty-six possible working designs. Of these, six designs were selected as holding considerable promise for a 1 Kw-Hr (usable, 2:1 speed range) anisotropic material flywheel including three biannular designs, one triannular, one multimaterial multi-ring and one single-material multiring. Several of these designs can meet all the design objectives/constraints imposed for the transportation application even for the 1.0 Kw-Hr usable energy requirement. S2-glass, AS-Carbon and Kevlar 49 were identified as the desirable materials for the manufacture and testing programs.
