Abstract
Abstract The invention relates to rotary inertial energy storage devices comprised of wound filaments or discrete rings of essentially anisotropic material formed into a rim or disc-like configuration. Pairs of adjacent rings or windings in any given plane perpendicular to the axis of rotation of the present structure are tied or bonded together at discrete peripheral points at selected locations while adjacent rings which are not bound at these first-mentioned tie points are tied together at other peripheral points interdigitated between said first-mentioned tie points. These points of connection extend linearly throughout the structure.
