The faster the limb tips go from full draw to brace the faster the bows gonna be. So a recurve since it moved the limb tip from drawn to brace faster moves the string faster therefore moving your arrow faster.
@smorris65399 ай бұрын
But, if you move faster, you need a stronger arrow. A stronger arrow has more mass. More mass decreases acceleration. Less acceleration means slower speed. Certain materials have max capacity. The only way to push the limits is to decrease safety. So every time you draw a failure is more likely. Modern bows have limits, too. As do firearms. Sometimes, a maximum is a maximum for many reasons.

all bows approach "infinite speed" as they reach brace draw weigh has little impact on arrow speed more impact on weight of arrow it can PUSH
@connorgarland11312 күн бұрын
Then again the faster the arrow goes from braced to drawn, the less energy can be stored due to either string angle or higher brace height.

@jonathanp___________360611 күн бұрын
If you plot the draw weight at each moment (for release of the string to the moment the arrow starts to leave the string) vs. time, the speed of the arrow should be the area under the curve divided by the mass of the arrow. This doesn’t account for drag, but it does account for the sometimes counterintuitive tradeoff between the time an arrow spends in the bow, and how fast it ends up moving.
@TheCompleteMental9 ай бұрын
Bigger bow, more extreme curve (like a C shape when unstrung), thin and solid tips to act like a lever. Traditional bows used sinew on the belly and horn and the back, all glued together. Former is elastic, it stores more tension, latter is more rigid and stores more compression - any material with these qualities should work similarly. Lighter limbs also add speed: they have inertia just like the arrow does, so optimally you need to find a balance that can impart the most amount of the energy stored by drawing as possible within the time it's launching the arrow.

You have it backwards ... sinew is on the back while horn is on the belly. The belly material has to be dense with high compressive strength, while the material on the back has to be high in tensile strength such as sinew or bamboo.

Do laminated traditional bows with tapered laminates between non-tapered laminates tend to build up much higher limb speed due to the conflicting forces? If so make really thin tapered and non tapered limbs. What about running small diameter kevlar thread between the laminates? Idea being to use the incredible nature of kevlar to not stretch. Bending a bow limb means you gave to be streching the kevlar. What dynamic forces could be achieved with a nonstretch material?

One thing to consider is that the arrow is accelerating the entire draw length. My intuition is that higher early acceleration will result in a higher top speed. If you don't accelerate much till the end, you're sort of wasting time you could be putting energy into the arrow. I've been wrong before. Willing to be proven wrong here.

1 inch brace height so all your draw is actually delivering draw weight to the arrow. Use the fastest string materials. Overdraw the bow to a ridiculous draw length. Severe backset, going to be a beast to string. Not a fun bow to work with at all. High draw weight maybe to 500 pounds. Will need some kind of let off mechanism, maybe a special drawing windlass. Moderate arrow weight, not too light, not a spear either. Fletching on arrows would have to be trim, lightly waxed arrows and bow with a low air friction coating. Maybe make the bow out of something like carbon fiber or aircraft grade aluminum, something with high strength to weight ratio. We're outside of traditional wood here so maybe doesn't count as traditional. Wilcox limbs that curl and unfurl as you draw. Limbs hollow so the tension and compression surfaces take all the forces and no dead weight in the core of the bow.

shorter working limb and make the nock ends stiff, remove their ability to flex. i am into Asiatic or horse bows as they are known and sure enough i have several different types by now. for instance i have two Turkish style bows and two Mongolian style bows. of the two Turkish style the one i have which properly copies the ottoman sipahi is faster by a considerable amount despite being only three pounds heavier on my scale. the differences are the sipahi has shorter working limbs and longer siyahs, the other Turkish also lacks string bridges which so far as i can tell means there are three reasons it is so much slower. still a lovely bow to shoot though. the Mongolians are a better example to be fair because the slowest of the two different types of Mongolian i have is much heavier in draw weight. the differences between the two are the same, the lighter and yet faster bow has shorter working limbs and considerably longer siyahs although neither have string bridges. the reason i believe that the only bow i have capable of outperforming my sipahi on arrow speed is my compound is because the siyahs and the string bridges act in the same way as a compounds cams do. Hope this helps Brother. 😊

So from what I know about basic stuff it's about the energy stored plus the energy forced so if one is lacking then it won't go any faster and all things have a limit of storage and force of this energy so it maybe the material used! But sometimes when we multiply the material we can store more or force more. I think you have dedicated more time then anyone to know if the boundaries have been meet. If you do keep going I would love to watch. You find things and explain things very well so don't take this as a fail just because the limits of the material have been found but a foundation of what you have to work with! Good luck and my God bless you. I hope you find an answer.

@@musikSkool 500fps is aproximatelly the speed of the string when you shoot without an arrow. In fact, the more power you get, the heavier you limbs will be and the heavier your arrows will need to be. A 150# longbow shoot at 190fps when a 50# shoot at 175fps. The gain is not that big. If you want to gain speed, you have basically three levers. - arrow/# ratio, but the more you will go down, the less the energy transfert will be efficient. ( And the max speed will be determined by bow design, limbs length, limbs weight and shape) - draw length and stroke, the longer you push the arrow, the more you give it energy - bow design, you need the lightest limbs possible and a shape that make the draw curve that looks as closest as possible to a constant curve that is at the max draw. ( I guess that if you make spiral limbs, the draw will be the most constant, you can see a try with border and morisson limbs that have big curved limbs, when you pull them, it's really constant, you even have the feeling that there's a let off in the begening)
