Archery



#Archery (G) is the #art, practice, or skill of propelling #arrows (G) with the use of a bow, from Latin #arcus. Historically, archery has been used for hunting and combat, while in modern times, its main use is that of a competitive #sport and recreational activity. A person who participates in archery is typically known as an "#archer" or a "#bowman", and one who is fond of or an expert at archery can be referred to as a #toxophilite (G)

#Bowandarrow (G)
While there is great variety in the construction details of bows (both historic and modern), all bows consist of a string attached to elastic limbs that store mechanical energy imparted by the user drawing the string. Bows may be broadly split into two categories: those drawn by pulling the string directly and those that use a mechanism to pull the string.
Directly drawn bows may be further divided based upon differences in the method of limb construction, notable examples being self bows, laminated bows and composite bows. Bows can also be classified by the bow shape of the limbs when unstrung; in contrast to simple straight bows, a recurve bow has tips that curve away from the archer when the bow is #unstrung. The cross-section of the limb also varies; the classic longbow is a tall bow with narrow limbs that are D-shaped in cross section, and the #flatbow has flat wide limbs that are approximately rectangular in cross-section. The classic D-shape comes from the use of the wood of the yew tree. The sap-wood is best suited to the tension on the back of the bow, and the heart-wood to the compression on the belly. Hence, a cross-section of a yew longbow shows the narrow, light-coloured sap-wood on the 'straight' part of the D, and the red/orange heartwood forms the curved part of the D, to balance the mechanical tension/compression stress. Cable-backed bows use cords as the back of the bow; the draw weight of the bow can be adjusted by changing the tension of the cable. They were widespread among Inuit who lacked easy access to good bow wood. One variety of cable-backed bow is the Penobscot bow or Wabenaki bow, invented by Frank Loring (Chief Big Thunder) about 1900. It consists of a small bow attached by cables on the back of a larger main bow.

Modern #recurvebow (Takedown)
Compound bows are designed to reduce the force required to hold the string at full draw, hence allowing the archer more time to aim with less muscular stress. Most compound designs use cams or elliptical wheels on the ends of the limbs to achieve this. A typical let-off is anywhere from 65%–80%. For example, a 60-pound bow with 80% let-off will only require 12 pounds of force to hold at full draw. Up to 99% let-off is possible. The compound bow was invented by Holless Wilbur Allen in the 1960s (a US patent was filed in 1966 and granted in 1969) and it has become the most widely used type of bow for all forms of archery in North America.
Mechanically drawn bows typically have a stock or other mounting, such as the crossbow. They are not limited by the strength of a single archer and larger varieties have been used as siege engines.

Arrow
The most common form of arrow consists of a shaft with an arrowhead attached to the front end and with fletchings and a nock attached to the other end. Arrows across time and history are normally carried in a container known as a quiver, which can take many different forms. Shafts of arrows are typically composed of solid wood, bamboo fiberglass, aluminium alloy, carbon fiber, or composite materials. Wooden arrows are prone to warping. Fiberglass arrows are brittle, but can be produced to uniform specifications easily. Aluminium shafts were a very popular high-performance choice in the latter half of the 20th century due to their straightness, lighter weight, and subsequently higher speed and flatter trajectories. #Carbonfiberarrowsbecame popular in the 1990s and are very light, flying even faster and flatter than aluminium arrows. Today, arrows made up of composite materials are the most popular tournament arrows at Olympic Events, especially the Easton X10 and A/C/E.
The arrowhead is the primary functional component of the arrow. Some arrows may simply use a sharpened tip of the solid shaft, but it is far more common for separate arrowheads to be made, usually from metal, stone, or other hard materials. The most commonly used forms are target points, field points, and #broadheads, although there are also other types, such as#bodkin#judo, and #bluntheads.

Shield cut straight fletching – here the hen feathers are barred red
Fletching is traditionally made from bird feathers. Also solid plastic vanes and thin sheetlike spin vanes are used. They are attached near the nock (rear) end of the arrow with thin double sided tape, glue, or, traditionally, sinew. Three fletches is the most common configuration in all cultures, though as many as six have been used. Two will result in unstable arrow flight. When three-fletched the fletches are equally spaced around the shaft with one placed such that it is perpendicular to the bow when nocked on the string (though with modern equipment, variations are seen especially when using the modern spin vanes). This fletch is called the "index fletch" or "cock feather" (also known as "the odd vane out" or "the nocking vane") and the others are sometimes called the "hen feathers". Commonly, the #cockfeatheris of a different color. However, if archers are using fletching made of feather or similar material, they may use same color vanes, as different dyes can give varying stiffness to vanes, resulting in less precision. When four-fletched, often two opposing #fletches are cock feathers and occasionally the fletches are not evenly spaced.
The #fletching may be either parabolic (short feathers in a smooth parabolic curve) or shield (generally shaped like half of a narrow shield) cut and is often attached at an angle, known as helical fletching, to introduce a stabilizing spin to the arrow while in flight. Whether helicial or straight fletched, when natural fletching (bird feathers) are used it is critical that all feathers come from the same side of the bird. Oversized fletchings can be used to accentuate drag and thus limit the range of the arrow significantly; these arrows are called flu-flus. Misplacement of fletchings can often change the arrow's flight path dramatically.

Bow string
Dacron and other modern materials offer high strength for their weight and are used on most modern bows. Linen and other traditional materials are still used on traditional bows. Almost any fiber can be made into a bow string. The author of "Arab Archery" suggests the hide of a young, emaciated camel. Njál's saga describes the refusal of a wife, Hallgerður, to cut her hair in order to make an emergency bowstring for her husband, Gunnar Hámundarson, who is then killed.

Bracer, Finger tab and Thumb ring

A right-hand finger tab to protect the hand while the string is drawn.
Most archers wear a bracer (also known as an arm-guard) to protect the inside of the bow arm from being hit by the string and prevent clothing from catching the bow string. The bracer does not brace the arm; the word comes from the armoury term "brassard", meaning an armoured sleeve or badge. The Navajo people have developed highly ornamented bracers as non-functional items of adornment. Some archers (mostly women) also wear protection on their chests, called chestguards or plastrons. The myth of the Amazons was that they had one breast removed to solve this problem.Roger Ascham mentions one archer, presumably with an unusual shooting style, who wore a leather guard for his face.
The drawing digits are normally protected by a leather tab, glove, or thumb ring. A simple tab of leather is commonly used, as is a skeleton glove. Medieval Europeans probably used a complete leather glove.
Eurasiatic archers who used the thumb or Mongolian draw protected their thumbs, usually with leather according to the author of Arab Archery, but also with special rings of various hard materials. Many surviving Turkish and Chinese examples are works of considerable art. Some are so highly ornamented that the users could not have used them to loose an arrow. Possibly these were items of personal adornment, and hence value, remaining extant whilst leather had virtually no intrinsic value and would also deteriorate with time. In traditional Japanese archery a special glove is used, provided with a ridge which is used to draw the string.

Main article: Release Aid (Archery)
A release aid is a mechanical device designed to give a crisp and precise loose of arrows from a compound bow. In the most commonly used, the string is released by a finger-operated trigger mechanism, held in the archer's hand or attached to their wrist. In another type, known as a back-tension release, the string is automatically released when drawn to a pre-determined tension.

Stabiliser (archery)
#Stabilisers are mounted usually on the front of the bow below the handle and on the right side, below the handle to help aiming by keeping the bow steady.

A modern compound hunting bow
Using archery to take game animals is known as "bow hunting". Bow hunting differs markedly from hunting with firearms, as the distances between the hunter and the game are much shorter in order to ensure a humane kill. The skills and practices of bow hunting therefore emphasize very close approach to the prey, whether by still hunting, stalking, or waiting in a #blind or#treestand. In many countries, including much of the United States, bow hunting for large and small game is legal. Bow hunters generally enjoy longer seasons than are allowed with other forms of hunting such as black powder, shotgun, or rifle. Usually, compound bows are used for large game hunting and may feature fiber optic sights and other enhancements. Using a bow and arrow to take fish is known as "bow fishing"
