ABSTRACT:
The present is directed to a specific broadhead configuration for reducing the turbulence generated by a broadhead in flight, thereby reducing the resulting wind noise and aerodynamic drag generated in flight. The aerodynamic improvements to the archery broadhead are accomplished by providing edge treatments on at least one of the leading edges, trailing edges oblique edges or longitudinal edges of the broadhead blades. Specific edge treatments may include a linear tapered profile, a non-linear tapered profile or a radiused or rounded profile. Furthermore, certain edge treatments may be asymmetric so as to impart a rotational moment or spin to the arrow during flight. Such edge treatments are suitable for use on vented and non-vented blades.
