In typical fashion, Dorge had several new patents and new products for 2019. Despite my engineering degree, a lot of the science around Dorge’s products goes way over my head – at least during his first explanation or two. One system of his that caught my attention was his AeroConcept System (ACS) which he has continually refined over the years.
At first glance, I thought someone had been playing with a piece of micro-diameter shaft and stuck it in the end of a larger, “traditional” shaft. Dorge was quick to point out that this is an integral part of the system. Pull up some videos of slow-motion arrow flight and you’ll see a “wiggle” that all arrows have as they leave the bow and early in the flight. This is a wasted motion that steals a portion of your arrow’s energy throughout flight.
The Firenock Approach
Firenock’s elegant approach to this issue was to add a small Carbon Inner Tube directly behind the insert effectively creating one large insert. This reinforces the front of the arrow, which increases the spine in that particular section and harmonically dampens the oscillation so less energy is wasted. The 2.0 version of this system takes this a step further by adding a similar Carbon Inner Tube inside the back of the arrow, which increases the effect of the ACS by another 30-40%. Since you are losing less energy to the oscillations in flight you can expect a higher point-of-impact downrange as well as more energy delivered at the target.
The other thing that immediately stood out to me were the arrow shafts themselves. They had the typical weaved carbon fiber look that you usually associate with carbon fiber (unlike most of the carbon arrows currently on the market). Most of the first carbon arrows had carbon fibers that were linearly aligned then rolled into a tube. These arrows were very strong and light, but weren’t robust enough for hunting situations. Most arrow manufacturers now utilize a variety of cross-directional or helical wraps to help the shaft survive impacts from a few other angles. In typical Dorge fashion, this design needed to be improved; and improved it was.
Enter Firenock’s AeroWeave featuring three tightly woven carbon weave layers, one of these being a diamond weave, along with the linearly aligned carbon. Instead of 2K or 2.5K carbon fibers, Dorge uses 3.5K carbon (i.e. fibers in the AeroWeave are 1/5th the thickness of the fibers found in your typical arrows) in order to have many more, thinner layers. This gives a stronger arrow than traditional manufacturing methods, while keeping the shaft wall half as thick. The AeroWeave shafts run $159.95 per dozen.
For those of you that are looking for a more affordable solution, Firenock also offers their price-friendly SportWeave. This wraps a cross-directional pattern with a woven carbon outer shell to give many of the same properties as the AeroWeave, but at a lower price point of $89.95 per dozen. Both the AeroWeave and SportWeave feature pro-quality tolerances for straightness and weight at <0.0015″ and +/- 1 grain per dozen.
