Abstract : An analysis is presented for the development of the fiber patterns necessary to produce uniform fiber tension in a spinning filamentary disk. The family of fiber patterns for such isotensoid disks is described in terms of curvature, slope, and arc length, and means are suggested for obtaining polar-coordinate plots of the patterns. Included are diagrams of three of the patterns, a photograph of a model, and a discussion of the general characteristics of the family of allowable patterns. It was found that the isotensoid disk design with which the disk is covered by uniform-diameter fibers operates at half the stress of a simple hoop, for a given tip speed and fiber mass per unit length.
