Currently used for sporting events and leisure, it is almost impossible to see it on the battlefield. Some special forces focused on quietness and were using it in practice, but almost all of them were destroyed and the silencer was passed with a gun. Even if you put a silencer on, you can’t hide the gunshot at all, but you can solve the problem by using a subsonic boom in the sonic boom caused by the supersonic of the bullet. Also, when a bow or crossbow bounces a protest, it makes a loud noise, so when you start to question that you can’t completely hide the sound, it becomes a gun, bow, or wavelength. Eventually, as long as the conditions are met, it is changing to use a silencer gun. In some African countries, such as Ethiopia, the tribal wars also face each other and shoot bows.
‘Arrow splitting arrows’ attracted considerable interest in the West, so I experimented with Discovery Channel Mythbusters, an American sponge.
In this case, the machine was tested because it focused on splitting rather than hitting it. So, the archery was done by archery player, but it was a little different. It was an experiment to shoot an arrow into a thin cylinder with an emphasis on hitting or not. In Miss Buster, a real arrow was shot twice to see if it could be broken. In other words, the subject was the same, but the contents of the experiment were different. In more detail, the goal set by Mythbusters was to reproduce the scene of the Robin Hood movie, so as the setting of the movie tried to split the full-blown British arrow in half. I succeeded in hitting the arrows of the first shot several times, but the arrowhead never split the arrows in half. The grain of the arrowhead was not uniform, so it was not split in half.
In fact, this is also impossible from a material dynamics point of view. Even if the arrow (arrow 2) that I shot hits the back of the arrow (arrow 1) that was inserted first, the speed at which the shock is transmitted to arrow 1 is faster than the time when arrow 2 penetrates arrow 1 and advances. It is presumed that in the old people’s mind, when arrow 2 is inserted from arrow 1, the amount of impact is transmitted as much as the speed at which arrow 2 advances, so it gradually splits and proceeds forward, eventually splitting the first arrow in half. However, in reality, the moment the arrow 2 touches the arrow 1, the amount of impact is completely transmitted to the entire arrow 1, and then the arrow 1 is destroyed even before the arrow 2 advances. If the grain of the wood is very constant, or if it is a polycarbonate made of Monacair-shaped two-headed arrows, it will split in half.
Also, the arrows do not fly straight. It’s not a parabolic story, but when shooting with a super-high-speed camera, it flies in an S-curve like a fish. Because of this, the transmission of physical force does not always go in a straight line, so you cannot cut a thin and long arrow exactly in half. In other words, Robin Hood-style arrow splitting is physically impossible.
Olympic and Asian games are opposed to the monopoly of medals, so if gold, silver, and bronze are from the same country, the bronze medal is awarded to the fourth place. When giving medals, the national flag hoists the third and fourth national flags side by side.
There are cases where the following objections are made.
- The hit rate was not very high, as in the case of the infantry.
- The bow can also overcome the hit rate problem by group shooting.
The Modern Bow Purpose
The power of the modern bow is roughly measured by the draw weight and draw length. The draw weight is the weight of the force it takes when the bow is full. That is how many pounds to walk down to the streets when the bow is fixed and the weight is put on the protest. Around 15 pounds (7 kg) for teenagers, less than 30 pounds (14 kg) for beginners, 50 to 60 (23 kg to 27 kg) pounds for athletes and hunting. In modern times, 100 pounds (45 kg) is a very strong bow. However, British archers from the Middle Ages to the Middle Ages reportedly wore 90 to 110 (40 kg to 49 kg) pounds, and in the case of the longbows found on the 16th-century British battleship Mary Rose, when using the arrows found, It is said to be 160 pounds (45-72 kg), and 100-180 pounds (45-81 kg) at full-time, regardless of arrows. The fact that this was an incredibly tense tension can be seen from the fact that archers around the world were literally astonished when it was speculated that this bow was a 150-pound tension object. Perhaps it was part of a desperate effort to somehow penetrate steel armour. In fact, it was said that some of the remains that were excavated were twisted to favor archery. In addition, the palace was used by a unit called Mangangdae, which was in charge of the guard of the king of the Joseon Dynasty. Each arch in the Ming Dynasty and the Ming Dynasty has a power of 120 pounds (158 pounds). The bow itself was stolen as a weapon, and since the game method is only an accuracy contest, simply insert it into the center of a predetermined distance, and penetrating power and range are neglected. Today, there is no reason to strengthen the performance of the distributed bow.) There are not many people who can handle the bow more accurately.
Draw length is the street of the best. Each person’s physique has a different distance and usually comes out by dividing the distance from your fingertips to the tip (measured in inches) by 2.5 inches. The height of both arms is almost the same as that of an ordinary person, so it is often based on height. However, if you have a tape measure, it is correct to use the arm length. Koreans tend to have shorter legs and slightly longer arms than their height. A regular bow like a recurve bow is fine even if the same bow is pulled a little less or more, but it is important to adjust the draw length due to the let-off spacing of the compound bow. If the draw length is not correct, the posture is bad and the bow trembles, resulting in poor accuracy.
In addition, it is supplemented with detailed figures such as the number of bullets and arrows shot by hand. The heavier the weight of the arrow, the more powerful it is, but the faster the arrow’s bullet speed, the faster and faster the trajectory and less aiming error. Compound bows and hunting gears focus on bullet speed, recurve bows, and training weights.
Although it is difficult to master, it is also noticeable in survivalism because of the fact that it is possible to make both bows and arrows with skill and materials, and that it is an unregulated or rare long-range projectile weapon with the power to be a war weapon until the appearance of overwhelming power.
Arrows are very important in archery. In some ways, an arrow may be more important than a bow. The most important factor for accurate shooting is the balance of bow force and arrow force. Here, the power of the arrow refers to the spine and the stiffness of the arrow itself. As soon as the arrow is fired, it is slightly bent by the law of inertia. At this time, the bow tension and the flexibility of the arrow must be in harmony so that the arrow can be sent straight to the target.
There are four kinds of arrows.
In recent years, almost all of the carbon, or an arrow made of carbon and aluminum, is predominant. It is because elasticity is good, even if it bends, it is restored to a magnetic shape again.
Aluminum is used a lot in the past because it is difficult to straighten it once it is bent once, but it is rarely used now.
Wood is used in some mania layers, and fiberglass is rarely used.
Stainless steel is commonly used as the material for the arrowhead (or pointer), but tungsten is used for the bow. The reason for using tungsten is that the mass of the metal is higher than that of stainless steel, so the same weight can be achieved with a small size. This is to send the center of gravity of the entire arrow toward the front as the arrowhead of a higher mass is used. The more the center of gravity is sent forward, the more the center of gravity in the air changes while the arrow is flying.
Classification by shape
Recurve Bow (Recurve Bow): In the rim of a bow bent forward and increases the tansok arrows.
Reflex bow: A sub-class of recurve bow. If the recurve bow is to the extent that the bow of the bow is bent forward, the reflex bow is the form in which the entire bow body is completely bent forward when the bow is released. When loosened, the archery that rolls forward like a horseshoe is a reflex bow, so to speak. It’s rare to pick a reflex bow and a recurve bow, and it’s not wrong to just say it with a rough recurve bow.
Longbow. Generally speaking, a longbow refers to a traditional British longbow or similar type of self-bow.
Flatbow: A flat, flat bow with a bow section. Traditional longbows have a D-shape or round cross-section, many of which do not contribute to actual bow performance. The flat bow draws elasticity with its wide flat wings.
Some of the Native American tribes, the Inuit, and people in northern Europe in the Finnish region have traditionally used this form of bow, unlike the British longbow, which relies heavily on a particular piece of wood, was able to bring in a wide variety of wood, and performance It is also excellent, and it can be easily made of poorly grown trees in cold regions and is also suitable for manufacturing ‘composite’ palaces. The rim of the archery is the shape of a flat bow. The efficiency is much better than the traditional longbow because the entire rim contributes to performance.
Originally, the archery rim was developed by developing an American flat bow. In the United States, when archery events were close to traditional longbows, in the United States, a study was conducted in which the bow of a D-shaped longbow was cut and compared, saying, ‘I will tell you the superiority of the traditional British longbow!’ But the result was absurd, the D-shaped section virtually contributed little to the performance, leaving only a flat square section, and the bow worked! As a result, the efficiency and performance of the flat bows were reconsidered, starting with the shaving of useless flesh from the D-type longbow, making a laminated rim like a synthetic bow, and developing new materials such as fibreglass to develop them. It has reached modern archery. But, of course, it has its drawbacks. As it is carved out, it is less durable than a D-shaped bow like an English longbow.
Compound Bow (Compound bow): mobilizing the mechanical structure of the pulley such that enhanced the performance of the bow.
Cable backed bow: A form that gives strength and elasticity to the bow by attaching a strong and strong cable (string) to the back of the bow.
Traditionally, strings are made of animal tendons and modern synthetic fibres. So, to speak, something like a primitive composite bow. Even if the wood is poor, you can get decent elasticity. This structure was used by some of the Inuit and Native American tribes. Since it is a primitive structure, it seems to have moved to a more reliable composite bow in areas where material supply and demand are met.
Bear Bow: A bow that is not a bow that catches a bear and is not equipped with any additional equipment is called a barebow and is called a barebow. The spectrum is quite wide, so even a traditional longbow or recurves bow is bare bow unless it is separate, and even if it is a modern bow with the synthetic rim on a modern aluminium riser, it is barebow without a site or stabilizer.
Hollow rim design bow (HLD bow): This is a unique bow in the form of a hollow out of the material tree. The rim shape is U-shaped, with the concave part facing the user and the convex part facing the front. It is said that when the protest is pulled, the U-shaped rim is stretched, so it has the effect of weakening the tension, so it can be pulled gently compared to the tension. The tension increases slowly compared to the draw length compared to the longbow type bow. Also, it is said that since the bow is very light, the speed of restoring the bow is fast, so the speed of the arrow is high. It is difficult to believe 100% of the asserter’s words, not yet having done the exact experiment. The content can be seen here.
Various methods are used depending on the region and culture, or the characteristics of the bow. In general, the posture of the body (stands), how to hold the bow (grip), how to put your finger on the string (hooking), how to pull the bow (drawing an anchor), and how to release the arrow (release) depends on the judicial method. There are a wide variety of judicial methods, but the descriptions are based on commonly used judicial methods.
Stance and set
This is the basic leg posture for shooting a bow. You need to set the foot position first (stand), and set the centre of the fuselage right (set) to stabilize the shooting position.
The criteria for determining the stance that suits you are how comfortable and fit the posture is and how long you can shoot continuously.
Square. Also called a straight stance. Spread your feet 8 wide with your shoulders wide and point your body horizontally along the diagonal. The toes should be slightly open so that the toes match the diagonal line.
The biggest advantage is that it is easy to learn, and it is used from beginner to expert in the bow because it does not bias in the front, rear, left or right in the centre of the body. Therefore, a beginner must go through a position before finding an optimal posture for him. For that reason, it is the most visible stance on video media.
It’s not as bad as it doesn’t have any drawbacks, but since strings are the closest postures to the body, some discomfort can follow when using them depending on your physique.
Open. It is a stance that puts the foot of the bow side of the square on the diagonal line as it is, and puts the foot of the string-pulling side perpendicular to the centre of the diagonal line. It is a pose close to traditional shooting, and it is more natural and stable to the human body than a square stance. The advantage of being able to take is an advantage. In addition, as described above, the body is thick, making it a good posture for use by people with limited square stance.
In the case of the Assam traditional archery, it uses an open stance, but it is characterized by almost facing the body. When the bow is pulled, the waist rotates greatly. In the archery, this waist rotation emphasizes the most natural movement for the human body.
Other than that, it is an advantage that is not related to a bow, but because there are many sports or martial arts that take an open stance in addition to the bow, it is easy to learn if you are familiar with the open stance in other fields.
Closed. Contrary to the open position, the side of the bow-sliding foot goes toward the centre of the diagonal. It is also called Cross Stance for crossing the body.
Unlike the two stances described above, this pose has little benefit. Posture to avoid if possible.
However, war palaces, including the longbow, deliberately take a close stance to draw great power when shooting. At this time, the position of the feet is much wider than the shoulders, one knee is bent forward, and the body is bent forward and shot while blooming. In fact, it is good to see it as a stance for the palace.
How to grip on the handle of the bow. It is said to be zoom in Korean archery. Strictly speaking, it’s not exactly a way to “grab” the bow, but rather a way of putting your hand on the bow. This is because even if you do not hold the bow, there is no fear of slipping because the bow is pulled from the back.
The National Archery
Whether archery or national archery, this is a difficult part. The bow is not just pulling with one hand. You should push the bow with the arm with the bow (bow arm, zoom hand), pull the string with the arm with the arrow, and equalize the forces on both sides. At this time, the part that interferes most with the bow is, of course, the handle, so an important task when shooting the bow is to reduce the interference by gripping the handle immediately. In particular, archery is often not held at all to minimize this interference. For trainees, a sling between the index finger and thumb is almost essential. In the Olympic archery, shooters shoot their bows and then drop their bows almost every time, because it’s not a practical effect or fashion, but catches the bow inevitably.
If you grip the related video (English) correctly, the bow arm will turn about 1/4 in the clockwise direction, and the string will almost never come across. However, even if the grip is held correctly, sometimes individual body differences Depending on the string, the strings may be crossed. As the string hits the bow arm, the bow’s accuracy will drop, so you will wear protective gear to help guide the strings that bounce like this.
High. At all, slide your bow across your thumb and middle finger without touching your palm.
It has the least amount of interference with the bow and is the grip of the Olympic archery, especially female athletes.
Medium. It is the most common grip used in archery.
Slide the bow over the thumb of the palm below the lifeline.
Low. Use your entire thumb to push the bow. The bow can be reliably pushed out, but the length of pulling the string becomes slightly shorter.
Handful of Archery
In the case of the national archery, the root part of the thumb is aligned with the centre of the zoom tube (the holding part of the bow), and the upper intestine (the upper part of the bow) is tilted slightly forward, and it is slanted. When the bow is held, the string is twisted so that it is slightly off the width of the palm (called a knot), and when properly held and shot in this state, the protest moves naturally to the outside of the arm when the arrow exits. If you are in a good posture, the protest will never hit your arms, so beyond the beginner level, the National Palace does not require a cuff.
This is how you put your finger on the string. This is the most significant part of bow justice. In general, archery is one of the most popular Mediterranean type, archery in the Asian archery, including the use of the Mongolian type.
The Mediterranean. It is also called a split-finger because it spreads fingers.
The most commonly used hooking method in archery is vertically hanging an arrow between the index finger and middle finger, and stringing and pulling the tip of each finger along with the ring finger. If it is right-handed, an arrow is applied to the left rest of the riser. Although it varies depending on the person, the thumb joint naturally touches the jawbone while the bow is pulled to the maximum.
Compared to other hooking methods,
The most fingers are put, but the reason for changing to hang three fingers is that the shooter unconsciously does not twist the string. To consciously correct strings to be pulled in a line.
If only the index and middle fingers are used, it is called Flemish Draw or Hungarian Draw. It is known that as the number of fingers is increased, the burden on it increases, but the accuracy can be increased by reducing interference with the arrow.
The burden on the finger is lower than that of the Mongolian type, but still shooting for a long time can injure the finger ligament. If possible, wear protective gear such as shooting gloves or finger taps.
In addition, the three-under (three under) hanging all three fingers under the arrow for quick aiming at a short distance or focusing on the rate of fire. Three-under is a technique for high anchors, so it is often used by archery players because it has less interference with arrows due to the nature of the hooking method. Also, since the position of the arrow is much closer to the eye, it is also suitable as a hook for a bare bow that does not use a sight.
Pinch. Used to fire a relatively low-tension bow.
When a beginner catches an arrow for the first time by pulling the string horizontally by pinching the arrow between the thumb and index finger, it is often caught in this way. Unlike the vertical Mediterranean style, it pulls horizontally, so the back of the hand touches the chin. Even if you use the same tension bow, it is very difficult to use it with a strong bow because you have to hold the bow and hold the posture more strongly than the Mediterranean.
As a variant of the pinch, a metal ring was used at the tip of the thumb and forefinger, and records of ancient Greeks and Scythians, parts of the continental United States, and Thailand remain.
Thumb type (Mongolian type)
Thumb/Mongolian. It is the method used in most Asian countries.
It may look like a pinch, but you can pull a bow of stronger tension by hanging an arrow inside your thumb. Unlike the three-fingered Mediterranean type, a single thumb is used to protect all fingers, so a pod is used to protect the finger. Contrary to the Mediterranean type, it shoots with arrows on the right for right-handed and left for left-handed. There are many records left in the cultures where the palaces are used.
There are two types of drawing methods, linear and angular, respectively.
Linear Draw, also known as Straight Draw, is a method of literally pulling an arrow straight back and forth. Surprisingly, history is not long because it is difficult to master due to the structure of the human body. However, once you have mastered and corrected your posture, the aiming is easily aligned, and in particular, you can avoid various injuries because you do not use anything other than the back muscles. Because of this, it has spread rapidly from the archery world, starting, and has now become the basis of archery.
Angular Draw is a method of drawing arrows with a triangular line of arms when viewed from above. It is a traditional method of arching, sometimes referred to as a rotational draw because the appearance of pulling the bow all the way to the anchor seems to turn the arm. Compared to Linear, it is closer to natural archery, but inevitably, shoulder force is inevitably used in the drawing process, and the number of users has decreased due to the risk of injury.
How to pull and fix the arrow. It is divided into two types, high anchor and low anchor, depending on the anchor point. The key to forming a high impact force, the anchor point must always be the same for constant fire.
High Anchor is a method of fixing the anchor point near the mouth or behind the head. Since the arrow is placed closest to the eye and diagonal, you can aim with the arrowhead without using the aimer. It is safe to say that the traditional judiciary shoots as a high anchor.
Low anchors are a method of anchoring anchor points under the chin, especially under the molars. When shooting with a low anchor, the string touches the chin, lips, and nose neatly, and it is ideal. Unlike a high anchor, it is suitable for shooting using a sight.
How to lay strings to shoot arrows. It is divided into three categories based on archery.
The forward release is when a hooked finger goes forward with a bow. It’s a mistake that can happen to a beginner, and it’s hard to call it judicial.
Dead Release is a way to release only the strings as it is. This is the recommended release for beginners. However, when you get used to arching because you put your finger off the diagonal line, you will use a sliding release.
The sliding release is a method of releasing the string while pulling the hand back. It is good for getting a hit rate because the finger does not deviate from the diagonal. In the case of the traditional judiciary, the arm is sometimes blown back.
For reference, if you grip the wrong grip earlier, the string will hit the bow arm with a 100% chance of release. The higher the tension of the bow, the more stinging, bruising, and impact the bow’s accuracy.
As the weight of bows has increased in recent movies, bows have started to be used as better weapons in games. For example, in the Ninja Gaiden series, Super Ninja Ryu Hayabusa used a bow called Ssangyonggung as one of the weapons, and Crysis 3 was the new weapon that emerged in various advertisements, and the 2013 version of Tomb Raider also changed Lara’s main weapon from the previous twin pistol to a bow. Did. Link had been using the bow as the main weapon even before the bow became popular.
