An example flywheel energy storage device includes a continuously curved fiber-resin composite ovoid shell. Hubs are concentrically disposed within and outside the shell at the shaft. A plurality of radially oriented, fiber-resin composite helical wraps of uniform width are used to construct the ovoid shell and couple the shell to the hubs for co-rotation and torque transfer. Integrated internal structures are attached to the external ovoid shell and provide compression support for the external ovoid shell. Upon rotation, the ovoid shell elongates slightly to increase the flywheel effective moment of inertia at operational speeds.
