The Emerge of Aerovane IIISince the first Aerovane (Aerovane I) was introduced in spring of 2008, a lot about the Aerodynamics and Arrow-dynamics have not been fully understood. Through the wind tunnel testing, dual airfoil of Aerovane I produced results which were so complicated to analyze, thus this made us very difficult to understand the real effect of airfoil to the arrow flight. Also, it was believed that smooth surface of Aerovane I would decrease the air frictional drag, however the opposite is true; a slightly rough surface texture was proved to be more efficient in terms of Aerodynamics.
In response to the difficulties to unleash the full power of Aerovane I, we went to consult low-speed airfoil experts like Professor Michael Selig of the University of Illinois at Urbana-Champaign (UIUC) and afterwards Aerovane II was born. Aerovane II was designed to have multiple micro texturing zones in order to take advantage of Aerodynamics Elasticity Memory (AEM) (i.e. airfoil being elastically deformed to further promote circular lift meanwhile the change in angle of the leading edge enhanced it to cut through the wind), however this Aerovane II design is revised due to certain patent issues related to texturing. With the new surface texture on Aerovane II, there was a reduction in AEM factor, which this made Aerovane II a much easier vane to use and by 2010, Firenock introduced the Aerovane Jig to make fletching Aerovane II easy and make precision fletching easy.
From the experience of building Aerovane I, Aerovane II and with the introduction of Aerovane Jig, we have finally produced Aerovane III in 2013 and developed precision straight fletching method to unleash the full potential of Aerovane III. In brief, Aerovane III is a more aggressive design of Aerovane II incorporating new innovation such as winglet, 4 different Aerodynamics micro-texturing zones and better crosswind handling ability etc.
