ABSTRACT:
A fletching for guiding and stabilizing the flight of an arrow. The fletching has an outer vane portion providing a turbulent flow of air over this outer portion and an inner vane portion providing a laminar flow of air over this inner portion at flight velocity. The height of the smooth inner vane portion provides a moment arm for transmitting the effects of outer vane portion turbulence to the arrow shaft.
