Firenock: Aerovane II

    Aerovane is the first ever vane that employed Airfoil Technology for archery arrows.  Thus Aerovane does not look like and does not work like traditional vanes.  Aerovane is not flat, it is shaped like an airplane wing and it works like an airplane wing.  Traditional vanes use drag to induce arrow rotation, thus there is a huge loss in energy/speed of your arrow.  Aerovane utilizes its Airfoil Technology to initiate arrow rotation, thus there is virtually no loss in energy/speed of your arrow. Aerovane also flies quieter than traditional vanes as Aerovane is modeled after an owl's wing.  Aerovane can make your archery projectile flying flatter and straighter and your shots will be more accurate and quieter.  You can shoot Aerovane with confidence. Aerovane is designed in US Illinois and is US patented (US Patent # 8105189).

How does the Aerovane work?
    Unlike traditional vanes using drag to induce rotation, the Aerovane uses an airfoil to create spin/rotation.  The Aerovane basic working mechanism is based on Bernoulli's principle.  This fundamental principle states that when airflow speed increases, pressure decreases and vice versa and this principle is widely used in design of airplane wing.  The airplane wing is designed to allow air to flow more rapidly over the upper surface than the lower surface, thus the pressure over the upper surface is lower than that over the lower surface creating a lift force to keep the airplane in flight. In the case of Aerovane, the principle is the same.  Air flows faster on one side than the other side of the vane and as there are multiple vanes on the arrow shaft, the arrow rotates in a circular fashion causing the arrow to spin / circular lift to occur.

Why Aerovane flies so quiet?

There are 3 main contributing factors that make Aerovane flies so quiet:

  1. Rigid airfoil: By having a rigid airfoil, wow and flutter (also known as harmonics) are minimized.  Aerovane is one of the hardest vanes on the market and it also employs the design of an ultra slim pyramid which gives Aerovane a rigid structure.
  2. Round leading edge: Aerovane is modeled after an owl's wing.  The edges of Aerovane are round which allow air to flow over with minimum air molecule to air molecule disturbance.  This also minimizes the formation of a delta vortex, which could rob speed and create sound.
  3. Surface micro texturing: There are 3 zones of micro-texturing on each side of the Aerovane surface.  The micro-texturing is designed to minimize back end turbulence and vacuum back pressure, meanwhile the micro-texturing generates micro turbulence to minimize surface to air drag (i.e. friction).

Aerovane™ II features:

  1. Aerovane II is modeled after the owl wing, which is the only bird wing that flies with no sound.  The true owl wing frontal design makes Aerovane II fly quieter than other vanes.
  2. The Airfoil Technology on Aerovane II uses Airplane principle to induce rotation instead of using drag (e.g. helical fletch) to induce rotation.
  3. True ultra slim pyramid design for structural integrity which means Aerovane II has very little bending, flapping, or fluttering.
  4. Wind channel for structural flexibility.
  5. 3 different surface textures on each side of Aerovane II for minimal turbulence and maximum air speed.
  6. Minimum delta wing surface vortex formation for minimum drag.
  7. Minimum 1st or 2nd stage turbulence.
  8. Higher down range speed than most common arrow vanes.
  9. Made of rigid material for maximum structural rigidity and steering ability.
  10. Easy to bond with fletching glue such as Firenock AG0600 / AG0GEL.
  11. Designed in US Illinois and US Patented (# 8105189)

Specification of Aerovane II

  1. Height : 0.55"
  2. Length : 1.967"
  3. Weight : 6.48 grain (+/- 0.2)
  4. Colors : 10 choices (red, pink, orange, yellow, green, lime, blue, black, white, clear)


  1. Aerovane II must be fletched straight to perform best.
  2. For best results, fletch Aerovane II with the Aerovane Jig with clamp, or Bitzenburger jig with a zenith conversion kit with the Aerovane Straight Stainless Steel Clamp for arrows shooting at no less than 280 fps.
  3. Aerovane II works best with a bow with close to perfect nock travel.
  4. Aerovane II works best with arrow length not shorter than draw length.
  5. Aerovane II works best with a full containment rest (e.g. AeroRest, Hostage Pro, QuickTune 360 with uneven nock travel bows).
  6. Aerovane II can work with a worn out Whisker Biscuit arrow rest as Aerovane II has a thick frontal end, which it can open the bristles and let the vane pass through the rest with minimal drag.

Aerovane II Test Result in February 2009 by Firenock Prostaff Jeff Bailey

    Upon completion of the Aerovane II Testing in January, I was eager to hit the range again for additional testing of this awesome vane.  This time I increased the testing requirements by a step or two.  The first step I added was to actually measure the spine of each arrow I was using; which will be discussed in a following paragraph.  The next step was to add a testing requirement of Group Testing at a distance of 40 yards.  The final step was to use a Full Capture rest vice a drop away as I did in the last testing.  By using the NAP Quicktune 360, I am forcing the arrow to keep on track all the way until it leaves the bow; this is necessary since the bow I am using, 2009 PSE X-Force Dream Season set at 67 pounds, has uneven nock travel.

    In order to measure the actual spine of the arrows I am testing, I used the RAM QC Arrow Spine Tester.  I also checked to see if there were any weak or thinner spine areas of each arrow.  If there were, I would use this location to place my cock vane.  In other words, I would place the thickest part of the each arrow against my rest for testing consistency.  Just to note, the Trophy Ridge Crush arrows did not have any noticeable change in spine when placed on the tester.

    After weighing and computing the Front of Center for each arrow, I proceeded to the shooting portion of the test.  As with the testing I completed in January, chronograph testing at three different yardages was next on the list. As expected, the lightest (High Country Speed Pro Max) arrow came off the blocks the fastest, whereas the heaviest arrow (A/C Super Slim 340) was the slowest.  However, the interesting point is each arrow fletched with the Aerovane II only slowed an average of 9 fps over the 20 yard distance.  The arrows with the Blazer vane attached slowed down an average of 11 fps.

    Shooting the arrows at a vertical line 40 yards away, then with a 100 grain G5 Striker Broadhead 30 yards away were the same tests I conducted in January.  The new test this time around was Group Testing at 40 yards. In this test, I shot both arrows at the same target 40 yards away, then measured the distance between the two arrows.  Surprisingly, the lightest arrow was one of the arrows with the greatest distance; whereas the heaviest arrow was close to the top in this test.

    At the end of the testing, three arrows stood out from all of the others.  The first two were from Trophy Ridge, and the third was Gold Tip CAA 350.  All of these arrows flew like darts.  Even though Gold Tip hit to the right on both the vertical line and broadhead test, with minor adjustments to the sight, they will be hitting the mark.

    The benefit of the Aerovane II is plain to see no matter which arrow type you prefer.  Through the use of a full capture rest on a bow with uneven nock travel, and fletched with Aerovane II will make your arrows shoot like darts.

Aerovane II Test Result on March 16 2009 by Firenock Prostaff Jeff Bailey

    I wanted to let you know the results from my testing of the Aerovane II placement this past weekend.
    I first started off placing the Aerovane II as far forward on the fletching clamp as possible.  This equated to a distance of 3 inches from the center of the nock to the back end of the vane.  Unfortunately, since I have adjusted my bow, placing the vane this far forward on the arrow actually places the vanes in front of the cables before I even start to draw the bow.  Every time I shot, the arrows would contact the cables and the arrow would be deflected way off target.
   I then decided to try again this time moving the vanes forward 0.25 inches at a time.  I set up three arrows; 1 with a distance of 1.25 inches between the center of the nock and the back of the vane (this is my normal set up); 1 with a distance of 1.50 inches; and 1 with a distance of 1.75 inches between the center of the nock and the back of the vane.  Even at only 1.75 inches, the vanes still made contact with the cables (even through it was very slight).  The 1.25 and 1.50 arrows flew exactly the same when it came to broadheads and the vertical line test.  The strange part was with the chronograph test.  It seems the further forward the vane is, the slower the arrow became with distance.  The only explanation I could think of would be the vortices coming off the back of the vane would hit the remaining part of the shaft slowing down the arrow.
