Alavekiu’s Arrows

George Alavekiu made some beautiful flight arrows. These “one mile” arrow designs look ridiculously tiny considering the power of the bow used to propel them. The heaviest limb sets store as much as 280 ft-lb of energy over 18" of draw. If I assume 50% of that energy makes it to the arrow, and given a typical arrow mass of 125 grains, then the bow would yield speeds in excess of 700 fps.   Given the same assumptions, the lightest limb sets would deliver more than 550 fps to a 125 grain arrow.  I have no idea what efficiency to expect yet, but these limbs should shoot like never before with the latest advances in string material.
