3D Archery
Modern competitive archery involves shooting arrows at a target for accuracy and precision from a set distance or distances. This is the most popular form of competitive archery worldwide and is called target archery. A form particularly popular in Europe, North America, and South America is field archery, shot at targets generally set at various distances in a wooded setting. There are also several other lesser-known and historical forms, as well as archery novelty games. The World Archery Federation (WA, also and formerly known as FITA from the French ''Fédération Internationale de Tir à l'Arc''), composed of 156 national federations and other archery associations, is the governing body recognized by the International Olympic Committee. Various other large organizations exist with different rules. Target archery Modern competitive target archery is often governed by the World Archery Federation, abbreviated as WA (sometimes also referred to as FITA, from its former Fr ...

Accuracy And Precision
Accuracy and precision are two measures of ''observational error''. ''Accuracy'' is how close a given set of measurements ( observations or readings) are to their ''true value'', while ''precision'' is how close the measurements are to each other. In other words, ''precision'' is a description of '' random errors'', a measure of statistical variability. ''Accuracy'' has two definitions: # More commonly, it is a description of only '' systematic errors'', a measure of statistical bias of a given measure of central tendency; low accuracy causes a difference between a result and a true value; ISO calls this ''trueness''. # Alternatively, ISO defines accuracy as describing a combination of both types of observational error (random and systematic), so high accuracy requires both high precision and high trueness. In the first, more common definition of "accuracy" above, the concept is independent of "precision", so a particular set of data can be said to be accurate, precise, both, ...

Windage
Windage is a term used in aerodynamics, firearms ballistics, and automobiles. Usage Aerodynamics Windage is a force created on an object by friction when there is relative movement between air and the object. Windage loss is the reduction in efficiency due to windage forces. For example, electric motors are affected by friction between the rotor and air. Large alternators have significant losses due to windage. To reduce losses, hydrogen gas may be used, since it is less dense. There are two causes of windage: # The object is moving and being slowed by resistance from the air. # A wind is blowing, producing a force on the object. The term can refer to: * The effect of the force, for example the deflection of a missile or an aircraft by a cross wind. * The area and shape of the object that make it susceptible to friction, for example those parts of a boat that are exposed to the wind. Aerodynamic streamlining can be used to reduce windage. There is a hydrodynamic effect si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flemish Region
The Flemish Region ( nl, Vlaams Gewest, ),; german: Flämische Region usually simply referred to as Flanders ( nl, link=no, Vlaanderen ) ; german: link=no, Flandern is one of the three regions of Belgium—alongside the Walloon Region and the Brussels-Capital Region. Covering the northern portion of the country, the Flemish Region is primarily Flemish-speaking. With an area of , it accounts for only 45% of Belgium's territory, but 57% of its population. It is one of the most densely populated regions of Europe with around . The Flemish Region is distinct from the Flemish Community: the latter encompasses both the inhabitants of the Flemish Region and the Dutch-speaking minority living in the Brussels-Capital Region. Politics Immediately after its establishment in 1980, the region transferred all its constitutional competencies to the Flemish Community. Thus, the current Flemish authorities (Flemish Parliament and Flemish Government) represent all the Flemish people, includi ...

Popinjay (sport)
Popinjay or Papingo (an old word for ''parrot'', designating a painted bird), also called pole archery, is a shooting sports, shooting sport that can be performed with either rifles or archery equipment. The object of popinjay is to knock artificial birds off their perches. The rifle form is a popular diversion in Denmark; a Scottish variant is also known. The archery form, called ''staande wip'' in Dutch language and ''papegai'' (i.e. ''parrot'') in French language, French, is popular in Belgium, and in Canada among descendants of 20th-century Belgian emigrants; it is shot occasionally in the United Kingdom under the governance of the Grand National Archery Society. In Germany a traditional shooting at wooden birds placed on a high pole is called "Vogelschießen" (that is "bird shooting"). These are carried out either with small bore rifles or crossbows. Archery The archery form of popinjay dates back to at least the fifteenth century. The annual papingo (popinjay) tournament ...

Kilwinning Papingos
Kilwinning (, sco, Kilwinnin; gd, Cill D’Fhinnein) is a town in North Ayrshire, Scotland. It is on the River Garnock, north of Irvine, about southwest of Glasgow. It is known as "The Crossroads of Ayrshire". Kilwinning was also a Civil Parish. The 2001 Census recorded the town as having a population of 15,908. The estimated population in 2016 was 16,460. History According to John Hay, once the headmaster of the parish school in Kilwinning, "North Ayrshire has a history of religion stretching back to the very beginning of missionary enterprise in Scotland. The Celtic Christians or Culdees of the period of St Columba and St Mungo found here, in this part of Scotland, a fertile field for the propagation of the faith. Kilmarnock, Kilbride, Kilbirnie, are all, like Kilwinning, verbal evidence of the existence of 'Cillean' or cells of the Culdee or Celtic Church." In the distant past, the town was called Sagtoun, or Saint's Town, after St. Winning, the founder of an early s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Run Archery
Run archery is a shooting discipline connecting archery with running. It is similar to the sport of biathlon. History Run archery was developed during the 1990s by European archery associations. Since 2000, some countries in other areas like Russia, Hungary, the Netherlands and Germany have begun organizing annual national championships. Run archery was officially admitted as a discipline of the World Archery Federation in 2003. Rules Like in the sport of biathlon, participants start with running, and alternate between running and shooting series of three arrows at a target from away. For scoring, it does not matter whether the target is hit in the center or at the edge. For each missed shot the athlete must run a penalty loop. The number of laps and target sizes depend on age and bow type. At the end, the fastest athlete wins. The bow must be held in hand during running; arrows can be left at the shooting range A shooting range, firing range, gun range or shooting gro ...

Biathlon
The biathlon is a winter sport that combines cross-country skiing and rifle shooting. It is treated as a race, with contestants skiing through a cross-country trail whose distance is divided into shooting rounds. The shooting rounds are not timed per se, but depending on the competition, missed shots result in extra distance or time being added to the contestant's total. History According to ''Encyclopædia Britannica'', the biathlon "is rooted in the skiing traditions of Scandinavia, where early inhabitants revered the Norse god Ullr as both the ski god and the hunting god." In modern times, the activity that developed into this sport was an exercise for Norwegians as alternative training for the military. Norwegian skiing regiments organized military skiing contests in the 18th century, divided into four classes: shooting at mark while skiing at top speed, downhill race among trees, downhill race on big hills without falling, and a long race on flat ground while carrying a r ...

Turkish Archery
Turkish archery ( tr, Türk okçuluğu) is a tradition of archery which became highly developed in the Ottoman Empire, although its origins date back to the Eurasian Steppe in the second millennium BC. Traditional Turkish archery has been inscribed on the Representative list of the Intangible Cultural Heritage of Humanity by the Intergovernmental Committee for the Safeguarding of Intangible Cultural Heritage of UNESCO in 2019. History From the decline of military archery after the Battle of Lepanto, mainly flight archery was practiced, and Turkish bowyers specialized in weapons which were particularly good for imparting high velocity to very light arrows. The sport of archery declined gradually until the reign of Mahmud II who made great efforts to revive it. He also ordered his archery student, Mustafa Kani, to write a book about the history, construction, and use of these bows, from which comes most of what is now known of Turkish bowyery. In 1794, in a field outside London, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flight Compound UK Champs 2007
Flight or flying is the process by which an object moves through a space without contacting any planetary surface, either within an atmosphere (i.e. air flight or aviation) or through the vacuum of outer space (i.e. spaceflight). This can be achieved by generating aerodynamic lift associated with gliding or propulsive thrust, aerostatically using buoyancy, or by ballistic movement. Many things can fly, from animal aviators such as birds, bats and insects, to natural gliders/parachuters such as patagial animals, anemochorous seeds and ballistospores, to human inventions like aircraft (airplanes, helicopters, airships, balloons, etc.) and rockets which may propel spacecraft and spaceplanes. The engineering aspects of flight are the purview of aerospace engineering which is subdivided into aeronautics, the study of vehicles that travel through the atmosphere, and astronautics, the study of vehicles that travel through space, and ballistics, the study of the flight of projectil ...
