Abstract
Arrow vanes, devices and methods for improving arrow vane airfoils for compound arrows, crossbow arrows and traditional arrows, which improves flight characteristics over traditionally manufactured, configured and/or applied vanes. Compound bends in the base of the vanes can be done by clamping the vanes in a channel having a generally straight portion and a generally bent portion. The bent portion can have a helical right bend or a helical left bend. A fletching jig can be used to glue the compound bent bases of the vanes to sides of an arrow shaft.
Claims17
An arrow vane configuration, comprising:
- an arrow shaft having a tip end and a nock end;
- a plurality of compound bent aerodynamic vanes, each having a base;
- and
- mounts for mounting the bases of the compound bent aerodynamic vanes on the shaft, wherein the mounts form three dimensional airfoil vanes from the compound bent aerodynamic vanes, in order to provide for spin stabilized flights of an arrow having the three dimensional airfoil vanes.
A method of providing spin stabilization to an arrow, comprising the steps of:
- providing an arrow with an arrow shaft having a tip end and a nock end;
- providing a plurality of planar vanes;
- compound bending each of the planar vanes to the sides of the arrow shaft adjacent to the nock end to provide rigidity to the vanes, wherein the compound bending step includes the steps of:
- mounting a front base portion of the planar vanes to the arrow shaft in a generally straight orientation;
- and
- mounting a rear base portion of the of the planar vanes to the arrow shaft in a bent orientation that is more off-center than the front base portion;
- and
- increasing arrow speeds and increased accuracy and reducing fluttering when the arrow is shot from a bow.
A method of providing spin stabilization to an arrow, comprising the steps of:
- providing an arrow with an arrow shaft having a tip end and a nock end;
- providing a plurality of planar vanes;
- compound bending each of the planar vanes to the sides of the arrow shaft adjacent to the nock end to provide rigidity to the vanes, wherein the compound bending step includes the steps of:
- preforming a front base portion of the planar vanes in a generally straight orientation;
- and
- preforming a rear base portion of the of the planar vanes in a bent orientation, that is more off-center than the front base portion;
- and
- increasing arrow speeds and increased accuracy and reducing fluttering when the arrow is shot from a bow.
A method of providing spin stabilization to an arrow, comprising the steps of:
- providing an arrow with an round arrow shaft having a tip end and a nock end;
- providing a plurality of planar plastic vanes;
- applying the planar plastic vanes onto the round arrow shaft;
- and
- forming the planar vanes into three-dimensional airfoils that spin-stabilizes an arrow shaft in flight, wherein the forming step includes the steps of:
- providing a front base portion and a rear base portion for the vanes;
- bending the rear base portion to be more off-center than the front base portion, so that the front base portion is up to approximately 1 to approximately 3 degrees off center and the rear base portion is approximately 1 to approximately 20 degrees off center.
