Hi, I invented a new type of arrow stabilizer. It is an aerodynamic turbine that makes the arrow to be stabilized by rotation mainly. In my field tests I reach 15% increase in distance compared to standard fletched arrow. My bow is very weak, it consists of a bent bamboo stick and a string. The speed of my arrow is therefore very slow, i estimate 100 kmh-1. Now I am wondering what happens if I increase the speed. What happens if I mount the same stabilizer to an airplane flying 1000 kmh-1 instead of its rear stabilizers? Even more extreme case would be a rocket. It has the same overall shape as an arrow, uses same type of stabilization, but it flies much faster, say 40 000 kmh-1. How much fuel would this save? I read air drag increases with square of speed, but I am not sure how to estimate the distance increase resulting from more aerodynamic stabilization (which gets my arrow 15% further at 100 kmh-1). It is more tricky than that since not only does the arrow fly further, it also flies faster, which makes this whole question much more complicated. But let's say it flies just as fast, say I don't put the pedal all the way to the metal. What I figured was: Well, the rocket flies 400 times faster. That means that the difference would be 1.15^400. But that means it would fly 1,901,674,318,152,855,051,262,401 times further, which makes no sense. Can anyone help? What am I doing wrong? Can an airplane or a rocket benefit from this at all? Thanks a lot.
