Abstract:
An arrow vane system comprising:a cylindrical body; and a plurality of at least two identical, integral vanes evenly spaced around the circumference of said cylindrical body; wherein said body has a leading end of reduced diameter capable of attaching said vane to the aft end of an arrow shaft; wherein said body has a trailing end of reduced diameter capable of attaching said trailing end to an integral arrow nock; wherein each of said vanes comprises a leading portion that stands perpendicular to the circumference of said arrow shaft, rises in height from its leading tip, and lies in a plane parallel to the long axis of said body; and wherein each of said vanes further comprises a trailing portion that arches away from the long axis of said arrow shaft in a continuous compound arc of decreasing radius of curvature as a function of vane height, wherein the axis of curvature is perpendicular to said arrow shaft.
