This week on Archery 101, I run some test to see just how much speed does an arrow really lose.

Hey Greg! I'v been following you for many months now and I love your enthusiasm and your love for traditional archery. I have been shooting traditional for approx 30 years and slowly evolved into a not too consistent snap shooter. After seeing your vids on gap shooting I must say after a few months of practice, my accuracy has improved so much its really fun again. thank you again hope to meet you face to face sometime in the future.

Greg great video. Love what you said in the first part. I started laughing. It's very interesting once you get into the difference of fast arrows vs slow arrows. I know it had to be hard shooting through that small of space at 25-30 yards.

This is a very informative video. I have developed a theory. The fletching is going to spin the arrow. The first 10 yards the arrow goes from 0 rpm spinning to some high rpm. Once the rpm maxes out the drag decreases. At first the spiral fletching catches a lot of wind with no spin. I don't know how you kept the arrows inside the chrono. Great shooting. You could also have some fishtailing causing velocity loss when the arrow is yawed a lot but when the yaw angle is straight the velocity loss would be low. Precise arrow tuning has it's advantages I think.

Greg. According to Cliff Clavin, It’s a little known fact. That decrease in velocity drop off at 10 yards is due to the arrows having to spin up from the "Helical Fletching" in the first 10 yards. After the initial 10 yards, the arrow is fully spun up and the rotational energy pushes the fletching and it causes propulsion via the fletching. Like a boat prop. ;-) cheers

Thanks Greg for doing this as it is interesting to known what an arrow does for real as it travels and not what a machine makes it do. Now you need set the chrono up in one foot increases to find exactly where the arrow starts slowing down using the thinnest and fattiest arrows. ONLY JOKING.

Really interesting video. I never knew that the first 10 yards of arrow flight had such a significant influence on the speed of the arrow. I agree, good to know real world data and not only lab data. I am glad the engineers do that but agree that most of us can not come close to mimicking that. Thanks

@joesheehy7856 4 жыл бұрын
I would agree it the initial drag put on the fletching to correct the flight. Take away is, if you really want the speed, take the time a tube your arrows so you can shoot a smaller fletching.

Great experiment. Engineers often forget to ask God if their calculations were right. Drag is obviously a function of velocity because they isn't any when the arrow is stationary. As the arrow is at it's fastest as it leaves the string drag is also at its maximum.

I love this testing and video!! Maybe, and I dont know this, a stiffer spine would reduce the oscillation enough to result in less of an initial drop off. Maybe?

I might be getting 150fps out of my short bow. When I'm shooting more consistently, I'll try and chrono it. No surprises on the early loss of velocity. I think you are probably right about why. The arrow should fly more efficiently once the oscillation stops. Also at lower speeds there is going to be less drag. Just for sake of comparison, a .30 caliber 150gr spitzer bullet starts slowing at a rate of about 57g once it exits the barrel of a rifle at around 2800fps. That's according to Hatcher.

So that gets me to thinking now I wonder if your velocity will drop off if you use thumb release and torque. the bow a bit so the arrow doesn’t drag, I think it might not lose as much speed at 10 yards because it doesn’t wobble
@TradArchery101
@TradArchery101 Жыл бұрын
The arrow (if even close to good tune) should not touch the riser. The feathers will. When you release the string, inertia is what causes the arrow to bend. That bend in turn, ensures the arrow will not hit the riser. The twist used on thumb shooting gives no clearance or performance advantage. The arrow is already off the string before the archer can twist the bow. In fact, it might (I cannot say for sure) do more harm than good. By twisting the bow, the string is no longer traveling in a straight line and this fact would cause it to lose energy. Best way to keep speed? Good form and a clean release. I think the reduction in speed is from friction on the feathers. I think that initial push, combined inertia, bleeds off energy. As it travels, the arrow will flex less and thus bleed off less energy.

This makes sense the initial 10 yards is when the feathers are working the hardest, really shows why its important to tune your setup for the cleanest initial arrow flight. Thanks for doing this, I've wanted to but don't have access to a chrono.

Hi! I want to know, if the speed of an arrow increases at the instant it leaves the spring or does it maintain that speed till it starts to lessen? Are there forces that act upon the arrow that make it go faster than the speed potential created by the spring? Does oscillation of the body of the arrow affect its speed? Thank you for you time.
@TradArchery101
@TradArchery101 Жыл бұрын
I cannot see how an arrow can increase in speed once it leaves the string. There is no more power transfer. From what I have seen in testing, the drop off in speed is noticeble at 10 yards.

@@TradArchery101 I was confused then because at 4:27 minutes, you stated 145 grain. I was in my driveway with my chrony yesterday, shooting my Martin Saber that scales at 43.5 pounds (my 30 inch draw length) trying to replicate the fps with various weight arrows. With a 555 grain arrow I was able to get 148 fps max. With a 457 grain arrow I was able to get 160 fps max. With a 406 grain arrow I was able to get 170 fps. I finally dropped to a 303 grain arrow and was able to get 200 fps max. My bag target was so frozen that arrow bounced back out of its hole. I used a variety of arrows and tips that I had and scaled each set up before I shot repeatedly looking for the max number. All of this was done at a full arrow length from the front of my chronograph and I shot many multiple times to eliminate the errors and look for the consistencies. So I figured since my bow scales between your 38 and 48 I should get numbers approximately in between. I'm not trying to argue either just wanted to be able to add your findings into mine to get a better average data stream to use for theoretical calculations. UPDATE: I was able to make a 525 grain arrow and the results are consistent with yours. kzfaq.info/get/bejne/rpN-eJR13M3Fj30.html

@@Backin_Theday One thing I have found is that bows perform in no set manner. Here is a prime example: I have a Black Hunter Recurve, 30 Pounds and a Stealth Hunter Recurve, 30 Pounds. Using the exact same arrows, the Stealth Hunter is consistently 10 to 15 fps faster. All you can really do is "guesstimate".

Ok 12/168 = .071= *SEVEN PERCENT* Both bows dropped *SEVEN PERCENT* in the first ten yards. Just touching on the math. The rest of your measurements don't make sense to me. The big drop during the paradox is probably the most important take away.

You do know that an arrow is not and can not be in Paradox. The paradox is something that the archer sees. And that it only occurs on bows not cut to or past center. As for my measurements, It is just to give archers an idea of when an arrows losses speed (which can also be read as energy bleed off).
