Firenock:Aerovane III

The Emerge of Aerovane III

    When the first Aerovane (Aerovane I) was introduced in spring of 2008, a lot about Aerodynamics and Arrow-dynamics was not fully understood.  Also, it was believed that the 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 order to improve the design of Aerovane I, we went to consult low-speed airfoil expert, Professor Michael Selig, University of Illinois at Urbana-Champaign (UIUC) and afterwards Aerovane II was born.  The main feature of Aerovane II is single airfoil design and its surface has multiple micro texturing zones in order to take advantage of Aerodynamics Elasticity Memory (AEM) (i.e. The elasticity of Airfoil further promote circular lift as the change in angle of leading edge enhanced the Airfoil to cut through wind).
    With the experience of building Aerovane I, Aerovane II and with the launch of Aerovane Jig, Aerovane III was introduced in 2013. In brief, Aerovane III is a more aggressive design of Aerovane II.  Aerovane III incorporated Firenock latest innovations in vane design such as the winglet, large airfoil, 4 different Aerodynamic micro-texturing zones and low profile design.  Aerovane III is designed to handle strong crosswind.  You will be amazed when you shot your arrow with Aerovane III under 30 miles crosswind.  Aerovane III is the ultimate vane for today's high speed arrows.

Aerovane™ III features:

  1. Improved True owl wing frontal design for virtually no sound in flight, thus Aerovane III flies quieter than Aerovane II
  2. Lighter weight than Aerovane II. Aerovane III is 10mm in height or 29% shorter than Aerovane II and weighs only about 5.18 grain or just ~20% lighter than Aerovane II
  3. 4 different Aerodynamic texture zones (0.0402mm, 0.0201mm, 0.0150mm and 0.0005mm) in Aerovane III vs 3 different vertical texture zones in Aerovane II
  4. Larger airfoil surface area than Aerovane II to compensate shorter in height so that Aerovane III can have similar total lift and spin torque as Aerovane II
  5. Incorporation of winglet to improve Aerodynamics and further reduce induced drag by wind
  6. 130% higher efficiency against crosswind than Aerovane II (e.g. Arrow with Aerovane III should hit a target under 35 mph crosswind at 35 yard with archery projectile at 320fps as compared to Aerovane II under 25 mph crosswind at 35 yard)
  7. 350% higher AEM than that of Aerovane II (Higher AEM means better crosswind handling ability. The mechanism of AEM is that when the arrow with Aerovane is rotating, the frontal section of Aerovane will bend towards the center of rotation while the tail section will bend away from the center of rotation which results in an effective angle to counter the effect of wind)
  8. Designed in US Illinois and US Patented (# 8105189)

  1. Aerovane III should be fletched with Aerovane Jig and Aerovane Straight Stainless Steel Clamp.
  2. Aerovane III should be fletched straight for best performance.
  3. Aerovane III should be fletched straight and shot with arrow shooting at no less than 280 fps.
  4. Aerovane III performs best with a bow which has close to perfect nock travel.
  5. Aerovane II works best with arrow length not shorter than draw length.
  6. Aerovane III cannot shoot with a worn out Whisker Biscuit arrow rest.
  7. Aerovane III fletched with 1.5 degree offset can work with arrow shooting at low speed (~ 150 fps).
  8. Aerovane III requires aerodynamic design broadhead (e.g. RamCat with Single Bevel Grind Blades) to fly with as Aerovane III spins faster than Aerovane II.
