What does the deflection of the arrow mean?

Question 1: How is the bow and arrow deflection calculated? Is there a formula? More specifically ... 20 minutes deflection, to put it bluntly, is the softness and hardness of the arrow, which is related to the number of pounds of the bow you make and the length of the arrow. Generally speaking, the lower the pound, the softer the arrow, and the harder the arrow with the higher pound. In the process of flying, the arrow swings forward, and only when it is well placed can it be shot accurately. So whether the arrow is hard or soft will affect the accuracy of shooting. The standard measurement method is: This sign is based on a 29-inch fuel rod and placed at intervals of 28 inches. Minimum Xi Put a weight of 0.88 kg (1.94 lb) in the center of the pipe, and it bends down and drops 0.000 inch. Easton has a software that can help you choose an arrow. Generally, you can directly enter your personal index. It is not a big problem to choose according to the software test results.

Question 2: The deflection of bow and arrow is 10. Are you sure there is a saw as long as 32+? . . . . . It's amazing. . . . . If this distance is correct, you almost chose an arrow with 450-500 Rao. . . . .

Question 3: What is the use of "deflection" in the disturbance of arrows? Simply put, the deflection represents the hardness of the arrow. This "hardness" does not refer to the hardness of the material of the arrow, but whether the arrow is easy to bend or "throw" during flight.

For a bow without an arrow stand, it is easy to understand why the arrow is thrown up, because there is an included angle between the direction in which the bowstring bounces back and the direction in which the arrow slips out of the bow window. The thrust direction of the chord is inconsistent with the initial sliding direction of the arrow and does not act on the central axis direction of the arrow. This unbalanced force will inevitably lead to the lateral movement of the arrow, and the inertia of the arrow itself will hinder the lateral movement, thus causing the arrow to swing back and forth after sliding away from the bow window.

If the three-finger shooting method is used, the arrow will swing when it leaves the bow window, that is, under the push of the bowstring and the block of the bow handle, the middle of the arrow will twist to the right first and then swing back to the left, and so on. When arrows with different deflections are fired from the same bow, the shaking frequency and amplitude of the arrows will be different. An arrow with proper deflection should be when it leaves the bow window and its tail is thrown to the left to the maximum, so that the tail feathers will not touch the bow handle at all, and the arrow can fly to the target without interference. If the deflection is not appropriate, the collision and friction between the arrow and the bow handle will become unpredictable, which will obviously affect the accuracy of archery.

After the arrow flies out, it will throw a bow with an arrow platform. For the hunting bow with the arrow not completely centered, its principle is similar to that of the bow without an arrow platform, but because the arrow on the hunting bow is really closer to the center, it is relatively less affected by deflection than the bow without an arrow platform, that is to say, its fault tolerance rate for deflection is relatively high. However, for those bows that shoot arrows completely from the center, such as compound bows and aiming at recurve bow, the shaking of arrows is more caused by human factors such as the Rafah of strings and the way of unfolding. Therefore, on the other hand, it is extremely important to choose the correct deflection for those who play traditional bows without an arrow platform. Don't choose right deviation, one arrow in the east and one arrow in the west.

Question 4: What does recurve bow's arrow 600 700 mean? It reflects the hardness of the shaft. The smaller the data, the harder the shaft. Generally, high-pound bows use arrows with low flexibility, while low-pound bows use arrows with high flexibility.

Question 5: A 40-pound bow has a range of 70 meters. How many deflection arrows did you use? Thank you. What do you want?

Question 6: How to choose an arrow for a compound bow? 50-60 kg compound bow, it is recommended to use 24-28 g pure carbon arrow to disturb 340. If it weighs 70 kg, it is recommended to use 26-30 grams of pure carbon arrows to disturb 300.

The length should be 2 inches from the drawing. At present, the length of compound arrows on the market is mostly 75 or 80, as long as your pulling distance does not exceed 28,75.

At present, the cost performance of imported carbon arrows is relatively high, more than 400 a dozen; The higher end is Easton, ranging from six or seven hundred to several thousand dozens. If you don't take part in professional competitions, it's just ordinary practice, and the national carbon is enough for you. I recommend Phoenix 5575 foreign trade products, carbon, cost-effective. If you want something cheap, Aaron Arrow Workshop will buy 18 carbon arrows, which is enough for daily practice.

By the way, I have a lot of black diamond aluminum arrows around me, which are cheap and easy to use, and I never have to worry about exploding arrows.

Question 7: How many degrees of arrows should be used for a 70-pound bow? It is easy to find straightness. 300 and 340 can basically be used, but the weight is a problem, which does not hurt the bow. Aluminum arrows are basically ok, and carbon arrows are basically light. Generally, the carbon arrows in the compound bow count up to 5 grains per catty. This is the minimum standard, which is not good for long-term use of bows. But there are still suitable arrows in the bow merchant's shop. Please consult.

Question 8: How many grains and how many turns are appropriate for a backhand of 30 kg? 1 30 kg is suitable for using 2 10~300 grains of arrows with 700 turns.

2. Grains: historically used units of weight. Initially, in Britain, the weight of a barley was defined as 1 grain. 1 gram = 1/7000 lbs = 64.438+0 mg.

3. Deflection generally refers to load-bearing members (multi-fingered beams), which will bend when bearing loads, and bending to a certain extent will also be considered as damage. This degree of bending is called roundness. There are two main aspects of winding: on the one hand, the tension of itself; On the other hand, it is mainly the cracks on the lower side of the beam. Generally, the beam works with cracks, and the width of cracks is generally required to be 0.3mm, which will lead to excessive winding of the beam. Although the beam can continue to bear the load, it can be regarded as reaching the bearing limit.

4. recurve bow is a kind of bow that looks different from ordinary longbow from the side: the end of one bow arm of recurve bow without bowstring bends outward. One of the special definitions points out that the difference between recurve bow and other bows is that recurve bow's bowstring, that is, the winding person, is in contact with its bow arm. Compared with the straight-arm bow, recurve bow can store more energy, which makes the shot arrow have higher kinetic energy. So recurve bow can make it shorter than the ordinary bow, but it can keep its power. This advantage makes recurve bow suitable for places where long weapons can cause inconvenience, such as jungles, forests or horseback riding. Relatively speaking, the traditional straight long bow will have a "cascading" effect-that is, the more you pull the bow, the more force you need to pull the bow will increase significantly.

Question 9: 50 kg master 2 has a distance of 28.7. Please show me how long it will take you to see the arrow shaft, and then find an arrow selection software to point out the data, so that you can know what the pole you need looks like. See the original post >>
