Abstract
The invention is a system of arrow vanes of novel geometry. The leading edge of each vane is parallel to the long axis of the arrow shaft, and the trailing edge of each vane is deflected out of the plane of the vane like an airfoil causing rotation during flight. All vanes of the invention are identical with all deflected portions facing the same direction when the arrow is viewed down its long axis. The invention also includes one or more vents in the vane surface. Careful placement of these vents decreases aerodynamic drag upon initial release from a bow and also once rotational speed is achieved.
