| Abstract: |
An archery arrow comprising a shaft having a circular cross section with a forward end and a rearward end. The improvement comprises a vane system adjacent the rearward end of the shaft for stabilizing the flight of the arrow. The vane system comprises first and second vanes disposed diametrically opposite one another on the vane shaft. Each vane is defined by an integral member having an aerodynamic fin extending tangentially from one side of the shaft and supporting the vane so that the vane is spaced from the shaft, the spacing between the vane and the shaft decreasing from the forward end of the vane to the rearward end thereof so as to define a pocket between the vane and the shaft of decreasing volume from front to rear to create pressures upon the vane and the aerodynamic fin to cause the arrow to rotate.
