Abstract
An aerodynamic element (often referred to as a vane or fletching) that is operatively coupled to the nock end (the back) of an arrow that adds significant stability associated with vanes of similar height (referred to as 'high profile' in the archery community) without the noise (amplitude and frequency) commonly associated with such vanes while also providing low drag characteristics. The vane has an initial front or leading edge at a shallow initial angle relative to the axis of the arrow. When the vane is mounted at an angle (known as offset or helical) to the axis of the arrow, this front shallow initial angle (and area under it) is utilized as a vortex generator. This vortex mixes and therefore helps balance velocities in the lower pressure, large aft area which is initiated at a point along the leading edge that increases to a steeper angle relative to the initial angle. The top of the vane is parallel to the axis of the arrow for stability as well as sound advantages. The back edge of the vane then angles down at a steep angle in a straight line to help with noise as well as control airflow.
