A kite is a flying tethered object that depends upon the tension of a tethering system. The necessary lift that makes the kite wing fly is generated when air (or in some cases water[1] [2] [3]) flows over and under the kite's wing, producing low pressure above the wing and high pressure below it. In the context of a Fluid flow relative to a body the lift force is the component of the Aerodynamic force that is Perpendicular to the flow This deflection also generates horizontal drag along the direction of the wind. In Fluid dynamics, drag (sometimes called fluid resistance) is the force that resists the movement of a Solid object through a Fluid (a The resultant force vector from the lift and drag force components is opposed by the tension of the one or more lines or tethers. A rope is a length of Fibers twisted or Braided together to improve strength for pulling and Connecting. A tether is a cord that anchors something movable to a stationary point [4] The anchor point of the kite line may be static or moving (e. g. , the towing of a kite by a running person, boat,[5] or vehicle[6] [7]).
Kites may be flown for recreation, art or other practical uses. Recreation or fun is the expenditure of time in a manner designed for therapeutic refreshment of one's Body or Mind. Art refers to a diverse range of Human activities creations and expressions that are appealing to the Senses or Emotions of a human individual Sport kites can be flown in aerial ballet, sometimes as part of a competition. A sport kite is also commonly known as a stunt kite Developments in multi-line kites in recent years has allowed forms of Kite flying to develop into a Sport. Ballet is a formalized form of Dance with its origins in the French court further developed in France and Russia as a Concert dance Power kites are multi-line steerable kites designed to generate large forces which can be used to power activities such as kite surfing, kite landboarding or kite buggying. A power kite or traction kite is a large kite designed to provide significant pull to the user In Physics, a force is whatever can cause an object with Mass to Accelerate. Kitesurfing, kiteboarding, uses wind power to pull a rider through the water on a small Surfboard or a kiteboard (which is like a Wakeboard) Kite landboarding also known as Kiteboarding or Land kiteboarding or flyboarding is based on the ever-growing sport of Kitesurfing, where a rider on a surf-style board is pulled A kite buggy is a light purpose-built Vehicle powered by a traction kite (power kite. Kites towed behind boats can lift passengers[8] which has had useful military applications in the past. [9]

Approximately 2,800 years ago the kite was first invented and popularized in China, where materials ideal for kite building were readily available: silk fabric for sail material, fine, high-tensile-strength silk for flying line, and resilient bamboo for a strong, lightweight framework. China ( Wade-Giles ( Mandarin) Chung¹kuo² is a cultural region, an ancient Civilization, and depending on perspective a National Silk is a natural Protein Fiber, some forms of which can be woven into Textiles The best-known type of silk is obtained from cocoons Bamboo is a group of Woody perennial Evergreen Plants in the True grass family Poaceae, subfamily Alternatively, kite author Clive Hart and kite expert Tal Streeter hold that kites existed far before that time. [10] The kite was said to be the invention of the famous 5th century BC Chinese philosophers Mozi and Lu Ban. Mozi ( Lat as Micius, ca 470 BCE&ndashca 391 BCE was a Philosopher who lived in China during the Hundred Schools of Thought Lu Ban ( fl 5th century BC) was a Chinese carpenter philosopher military thinker statesman and contemporary of Mozi, born in the State of Lu By at least 549 AD paper kites were being flown, as it was recorded in that year a paper kite was used as a message for a rescue mission. Paper is thin material mainly used for writing upon printing upon or packaging [11] Ancient and medieval Chinese sources list other uses of kites for measuring distances, testing the wind, lifting men, signaling, and communication for military operations. [11] The earliest known Chinese kites were flat (not bowed) and often rectangular. China ( Wade-Giles ( Mandarin) Chung¹kuo² is a cultural region, an ancient Civilization, and depending on perspective a National Later, tailless kites incorporated a stabilizing bowline. Kites were decorated with mythological motifs and legendary figures; some were fitted with strings and whistles to make musical sounds while flying. [12]
After its appearance in China, the kite migrated to Japan, Korea, Thailand, Myanmar (Burma), India, Arabia, and North Africa, then farther south into the Malay Peninsula, Indonesia, and the islands of Oceania as far east as Easter Island. China ( Wade-Giles ( Mandarin) Chung¹kuo² is a cultural region, an ancient Civilization, and depending on perspective a National For a topic outline on this subject see List of basic Japan topics.

Since kites made of leaves have been flown in Malaya and the South Seas from time immemorial, the kite could also have been invented independently in that region. [12]
One ancient design, the fighter kite, became popular throughout Asia. Most variations, including the fighter kites of India, Thailand and Japan, are small, flat, roughly diamond-shaped kites made of paper, with a tapered bamboo spine and a balanced bow. Flown without tails that would hinder their agility, these highly maneuverable flat kites have a length of cutting line coated with an abrasive attached to the bridle, which is then tied to a light cotton flying line. Although the rules of kite fighting varied from country to country, the basic combat was to maneuver the swift kite in such a way as to cut the opponent's flying line. Fighter kites are Kites that are used for the sport of kite fighting [12]
Kite flying began much later in Europe than in Asia. While unambiguous drawings of kites first appeared in print in the Netherlands and England in the 17th century, pennon-type kites that evolved from military banners dating back to Roman times and earlier were flown during the Middle Ages. The Netherlands ( Dutch:, ˈnedərlɑnt is the European part of the Kingdom of the Netherlands, which consists of the Netherlands the Netherlands England is a Country which is part of the United Kingdom. Its inhabitants account for more than 83% of the total UK population whilst its mainland Ancient Rome was a Civilization that grew out of a small agricultural community founded on the Italian Peninsula as early as the 10th century BC [12]
During the 18th century tailless bowed kites were still unknown in Europe. Flying flat arch- or pear-shaped kites with tails had become a popular pastime, mostly among children. The first recorded scientific application of a kite took place in 1749 when Alexander Wilson of Scotland used a kite train (two or more kites flown from a common line) as a meteorologic device for measuring temperature variations at different altitudes. Alexander Wilson ( July 6, 1766 &ndash August 23, 1813) was a Scottish-American Poet, Ornithologist, naturalist Scotland ( Gaelic: Alba) is a Country in northwest Europethat occupies the northern third of the island of Great Britain. [12]
Three years after, in June 1752, in what is the most famous of kite experiments, the American inventor and statesman Benjamin Franklin, with the aid of his son, lofted a flat kite fitted with a pointed wire and silk sail on a hemp line during a thunderstorm. Benjamin Franklin ( April 17 1790 was one of the Founding Fathers of the United States of America. Somehow both father and son avoided electrocution as a metal key attached to the flying line became electrified. Franklin proved that lightning was the natural phenomenon called electricity, not the wrath of the gods. One immediate and practical outcome of the experiment was Franklin's invention of the lightning rod. A lightning rod (USA or lightning conductor (UK is a single component in a Lightning protection system.
Kites typically consist of one or more spars to which a paper or fabric sail is attached, although some, such as foil kites, have no spars at all. A textile is a flexible material comprised of a network of natural or artificial Fibres often referred to as thread or Yarn. Foil kites are soft kites based on the design of the Parafoil. Classic kites use bamboo, rattan or some other strong but flexible wood for the spars, paper or light fabrics such as silk for the sails, and are flown on string or twine. Bamboo is a group of Woody perennial Evergreen Plants in the True grass family Poaceae, subfamily Rattan (from the Malay rotan) is the name for the roughly six hundred Species of palms in the tribe Calameae, native to tropical Wood is hard fibrous lignified structural tissue produced as secondary Xylem in the stems of Woody plants notably trees but also shrubs Silk is a natural Protein Fiber, some forms of which can be woven into Textiles The best-known type of silk is obtained from cocoons Modern kites use synthetic materials, such as ripstop nylon or more exotic fabrics for the sails, fiberglass or carbon fiber for the spars and dacron or dyneema for the kite lines. Rip-stop nylon is a light-weight Nylon fabric with inter-woven ripstop reinforcement threads in a crosshatch pattern Fiberglass (also called fibreglass and glass fibre see Spelling differences) is material made from extremely fine Fibers of Glass. Carbon fiber reinforced plastic ( CFRP or CRP) is a very strong light and expensive Composite material or fiber reinforced plastic. Uses PET can be semi-rigid to rigid depending on its thickness and is very lightweight Ultra high molecular weight polyethylene ( UHMWPE) also known as high-modulus polyethylene ( HMPE) or high-performance polyethylene ( HPPE
Kites can be designed with many different shapes, forms, and sizes. They can take the form of flat geometric designs, boxes and other three-dimensional forms, or modern sparless inflatable designs. Kites flown by children are often simple geometric forms (for example, the diamond). In Geometry a kite, or deltoid, is a Quadrilateral with two disjoint pairs of Congruent Adjacent sides in contrast In Asia, children fly dried symmetrical leaves on sewing thread and sled-style kites made from sheets of folded writing paper.
Designs often emulate flying insects, birds, and other beasts, both real and mythical. The finest Chinese kites are made from split bamboo (usually golden bamboo), covered with silk, and hand painted. On larger kites, clever hinges and latches allow the kite to be disassembled and compactly folded for storage or transport. Cheaper mass-produced kites are often made from printed polyester rather than silk. Polyester is a category of Polymers which contain the Ester Functional group in their main chain
Tails are used for some single-line kite designs to keep the kite's nose pointing into the wind. Spinners and spinsocks can be attached to the flying line for visual effect. There are rotating wind socks which spin like a turbine. A turbine is a rotary Engine that extracts Energy from a Fluid flow On large display kites these tails, spinners and spinsocks can be 50 feet (15m) long or more.
Modern acrobatic kites use two or four lines to allow fine control of the kite's angle to the wind. Traction kites may have an additional line to de-power the kite and quick-release mechanisms to disengage flyer and kite in an emergency.
Kites have been used for military uses in the past for signaling, for delivery of munitions, and for observation, by lifting an observer above the field of battle, and by using kite aerial photography. Kitesurfing, kiteboarding, uses wind power to pull a rider through the water on a small Surfboard or a kiteboard (which is like a Wakeboard) Kite aerial photography (KAP is a Hobby and a type of Photography.
Kim Yu-Sin (or Kim Yushin), a Korean general, in 637 C. Kim Yusin (595-673 was a General in 7th-century Silla. He led the unification of the Korean peninsula by Silla under the reign of King E. rallied his troops to defeat rebels by kite lofting a burning ball. [13] Kites were also used by Admiral Yi of the Joseon (1392-1910) Dynasty of Korea. Yi Sun-sin (April 28 1545 – December 16 1598 also commonly transliterated Yi Soon-shin or Lee Sun-shin, Korean:이순신 was a Korean During the Japanese invasions of Korea (1592-1598), Admiral Yi commanded his navy with kites. Two Japanese invasions of Korea and subsequent battles on the Korean peninsula took place during the years 1592-1598 His kites had specific markings directing his fleet to perform his order. Admiral Yi was said to have over 300 such kites. The war eventually resulted in a Chinese and Korean victory; the kites played a minor role in the war's conclusion. War is an international relations Dispute, characterized by organized Violence between National Military units
In more modern times the British navy also used kites to haul human lookouts high into the air to see over the horizon and possibly the enemy ships, for example with the kite developed by Samuel Franklin Cody. [14] Barrage kites were used to protect London as well as the Pacific coast of the United States during the last century. [15][16] Kites and kytoons were used for lofting communications antenna. [17] Submarines lofted observers in rotary kites. A submarine is a Watercraft that can operate independently below water as distinct from a Submersible that has only limited underwater capability [18] The Rogallo parawing kite[19] and the Jalbert parafoil kite were used for governable parachutes (free-flying kites) to deliver troops and supplies. [20]
Kites have been used for scientific purposes, such as Benjamin Franklin's famous experiment proving that lightning is electricity. Benjamin Franklin ( April 17 1790 was one of the Founding Fathers of the United States of America. Lightning is an atmospheric discharge of Electricity, which typically occurs during Thunderstorms and sometimes during volcanic eruptions or Kites were the precursors to aircraft, and were instrumental in the development of early flying craft. Alexander Graham Bell experimented with very large man-lifting kites, as did the Wright brothers and Lawrence Hargrave. WikipediaWikiProject Aircraft.

Weather forecasting is the application of science and technology to predict the state of the atmosphere for a future time and a given location
Kites can be used for radio purposes, by kites carrying antennas for MF, LF or VLF-transmitters. This method was used for the reception station of the first transatlantic transmission by Marconi. Captive balloons may be more convenient for such experiments, because kite carried antennas require a lot of wind, which may be not always possible with heavy equipment and a ground conductor. A moored balloon is an inflated fabric structure often shaped like an Airship and usually filled with Helium that is restrained by a cable attached to the ground It must be taken into account during experiments, that a conductor carried by a kite can lead to a high voltage toward ground, which can endanger people and equipment, if suitable precautions (grounding through resistors or a parallel resonant-circuit tuned to transmission frequency) are not taken.
Kites can be used to carry light effects such as lightsticks or battery powered lights.
Kites can be used to pull people and vehicles downwind. Efficient foil-type kites such as power kites can also be used to sail upwind under the same principles as used by other sailing craft, provided that lateral forces on the ground or in the water are redirected as with the keels, center boards, wheels and ice blades of traditional sailing craft. Foil kites are soft kites based on the design of the Parafoil. A power kite or traction kite is a large kite designed to provide significant pull to the user In the last two decades several kite sailing sports have become popular, such as kite buggying, kite landboarding and kite surfing. Snow kiting has also become popular in recent years.
Kite sailing opens several possibilities not available in traditional sailing:

Kite festivals are a popular form of entertainment throughout the world. Peter Lynn (1946– is a New Zealand kitemaker Engineer and Inventor. They include small local events, traditional festivals which have been held for hundreds of years and major international festivals which bring in kite flyers from overseas to display their unique art kites and demonstrate the latest technical kites.
Kite flying is popular in many Asian countries, where it often takes the form of 'kite fighting', in which participants try to snag each other's kites or cut other kites down. Fighter kites are Kites that are used for the sport of kite fighting [25] Fighter kites are usually small, flat, flattened diamond-shaped kites made of paper and bamboo. Fighter kites are Kites that are used for the sport of kite fighting Tails are not used on fighter kites so that agility and maneuverability are not compromised. In Afghanistan this is known as Gudiparan Bazi. Afghanistan /æfˈgænɪstæn/ officially the Islamic Republic of Afghanistan ( Pashto: د افغانستان اسلامي جمهوریت, Some kite fighters pass their strings through a mixture of ground glass powder and glue. The resulting strings are very abrasive and can sever the competitor's strings more easily. The abrasive strings can also injure people. During the Taliban rule in Afghanistan, kite flying was banned, among various other recreations. The Taliban ( طالبان, also anglicised as Taleban; translation "students" is a Sunni Islamist, predominately
In Vietnam, kites are flown without tails. Vietnam (ˌviːɛtˈnɑːm Việt Nam) officially Instead small flutes are attached allowing the wind to "hum" a musical tune. There are other forms of sound-making kites. In Bali, large bows are attached to the front of the kites to make a deep throbbing vibration, and in Malaysia row of gourds with sound-slots are use to create a whistle as the kite flies.

There are safety issues involved in kite-flying, more so with power kites. Kite lines can strike and tangle on electrical power lines, causing power blackouts and running the risk of electrocuting the kite flier. Wet kite lines or wire can act as a conductor for static electricity and lightning when the weather is stormy. Kites with large surface areas or powerful lift can lift the kite flier off the ground or drag them into stationary objects. In urban areas there is usually a ceiling on how high a kite can be flown, to prevent the kite and line infringing on the airspace of helicopters and light aircraft.
