Kite (geometry), Kites
A kite is a tethered heavier than air flight, heavier-than-air craft with wing surfaces that react against the air to create Lift (force), lift and Drag (physics), drag forces. A kite consists of wings, tethers and anchors. Kites often have a bridle and tail to guide the face of the kite so the wind can lift it. Some kite designs do not need a bridle; box kites can have a single attachment point. A kite may have fixed or moving anchors that can balance the kite. The name is derived from the kite (bird), kite, the hovering bird of prey. There are several shapes of kites. The Lift (force), lift that sustains the kite in flight is generated when air moves around the kite's surface, producing low pressure above and high pressure below the wings. The interaction with the wind also generates horizontal Drag (physics), drag along the direction of the wind. The resultant force vector from the lift and drag force components is opposed by the tension of one or more of the rope, lines ...

Biplane
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. The term is als ...

Mozi
Mozi, personal name Mo Di, was a Chinese philosopher, logician, and founder of the Mohist school of thought, making him one of the most important figures of the Warring States period (221 BCE). Alongside Confucianism, Mohism became the most prominent, organized schools of the Hundred Schools of Thought throughout the period. The Mozi (book), ''Mozi'' is an anthology of writings traditionally attributed to Mozi and to his followers. Born in what is now Tengzhou, Shandong, Mozi and his followers argued strongly against both Confucianism and Taoism, with a philosophy emphasizing universal love, social order, the will of Tian, Heaven, sharing, and honoring the worthy. Mohism was actively developed and practiced across Warring States–era China, but fell out of favor following the establishment of the Qin dynasty in 221 BCE. While tradition assumes the destruction of many Mohist texts in 213 BCE as part of Emperor Qin Shi Huang's burning of books and burying of ...

Fier Drake (1634 Kite Woodcut)
Fier (; sq-definite, Fieri, Latin: ''Fierum'') is the seventh most populous city of the Republic of Albania and seat of Fier County and Fier Municipality. It is situated on the bank of Gjanica River in the Myzeqe Plain between the Seman in the north, the Vjosë in the south and the foothills of the Mallakastra Mountains in the southeast. Fier experiences a seasonal Mediterranean climate affected by its proximity to the Adriatic Sea in the west. Fier was founded in the 19th century by the Vrioni family and officially in 1864 by Omer Pasha Vrioni II, the father of Kahreman Pasha Vrioni (1889-1955). It is from the ruins of the ancient settlement of Apollonia which was founded in 588 BCE by Ancient Greek colonists from Corfu and Corinth, on a site occupied by Illyrian tribes. Fier is an important terminus in southwestern Albania and is served by the A2 motorway and SH 4 highway, forming a north–south corridor in Albania and part of the Adriatic–Ionian motorway. Name ...

Snow Kiting
Snowkiting or kite skiing is an outdoor winter sport where people use kite power to glide on snow or ice. The skier uses a kite to give them power over large jumps. The sport is similar to water-based kiteboarding, but with the footwear used in snowboarding or skiing. The principles of using the kite are the same, but in different terrain. In the early days of snowkiting, foil kites were the most common type; nowadays many kiteboarders use inflatable kites. However, since 2013, newly developed racing foil kites seem to dominate speed races and expedition races, like Red Bull Ragnarok (held on the Norwegian Hardangervidda plateau) and the Vake mini-expedition race (held at Norway's most northern Varanger peninsula). Snowkiting differs from other alpine sports in that it is possible for the snowkiter to travel uphill and downhill with any wind direction. Like kiteboarding, snowkiting can be very hazardous and should be learned and practiced with care. Snowkiting has become more po ...

Kite Buggying
A kite buggy is a light, purpose-built vehicle powered by a traction kite (power kite). It is single-seated and has one steerable front wheel and two fixed rear wheels. The driver sits in the seat located in the middle of the vehicle and accelerates and slows down by applying steering manoeuvres in coordination with flying manoeuvres of the kite. This activity is called kite buggying. The speed achieved in kite buggies by skilled drivers can range up to around 110 km/h (70 mph), hence protective clothing, including a safety helmet, is commonly worn. The kite buggy was promulgated by George Pocock (inventor) in the UK in 1827 and kite buggies were available commercially in US and UK in the late 1970s. Peter Lynn is generally attributed with the modern popularization of buggies and kite buggying with his introduction of strong, lightweight, affordable buggies in the early 1990s. Kite buggying is similar to land yachting, windsurfing or even yachting, and therefore much ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kite Landboarding
Kite landboarding, also known as land kiteboarding or flyboarding, is based on the sport of kitesurfing, where a rider on a surf-style board is pulled over water by a kite. Kite landboarding involves the use of a mountain board or landboard, which is essentially an oversized skateboard with large pneumatic wheels and foot-straps. Kite landboarding is a growing sport, and there are several competitions. Kite landboarding is attracting growing publicity although it is not yet as popular or as well known as kitesurfing. Technique Typically, kite landboarding takes place in large open areas where the wind is constant and there are no obstructions such as trees or people. Large hard-packed sandy beaches are typical landboarding locations because of the large space available and wind conditions. The rider starts off by getting the kite into a neutral position overhead. Once strapped onto the board, the rider can orient the kite such that it pulls the rider across the ground. This is do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kite Surfing
Kiteboarding or kitesurfing is a sport that involves using wind power with a large power kite to pull a rider across a water, land, snow, sand, or other surface. It combines the aspects of paragliding, surfing, windsurfing, skateboarding, snowboarding, and wakeboarding. Kiteboarding is among the less expensive and more convenient sailing sports. After some concepts and designs that emerged in the late 1970s and early 1980s were successfully tested, the sport received a wider audience in the late 1990s and became mainstream at the turn of the century. It has freestyle, wave-riding, and racing competitions. The sport held the speed sailing record, reaching before being eclipsed by the Vestas Sailrocket. Worldwide, there are 1.5 million kitesurfers, while the industry sells around 100,000 to 150,000 kites per year. Most power kites are leading edge inflatable kite, leading-edge inflatable kites or foil kites attached by about of flying lines to a control bar and a harn ...

Force
In physics, a force is an influence that can cause an Physical object, object to change its velocity unless counterbalanced by other forces. In mechanics, force makes ideas like 'pushing' or 'pulling' mathematically precise. Because the Magnitude (mathematics), magnitude and Direction (geometry, geography), direction of a force are both important, force is a Euclidean vector, vector quantity. The SI unit of force is the newton (unit), newton (N), and force is often represented by the symbol . Force plays an important role in classical mechanics. The concept of force is central to all three of Newton's laws of motion. Types of forces often encountered in classical mechanics include Elasticity (physics), elastic, frictional, Normal force, contact or "normal" forces, and gravity, gravitational. The rotational version of force is torque, which produces angular acceleration, changes in the rotational speed of an object. In an extended body, each part applies forces on the adjacent pa ...

Power Kite
A power kite or traction kite is a large kite designed to provide significant pull to the user. Types The two most common forms are the foil, and the leading edge inflatable. There are also other less common types of power kite including rigid-framed kites and soft single skin kites. There are several different control systems used with these kites which have two to five lines and a bar or handles. Foil kites consist of a number of cells with cloth ribs in each cell. It is the profile of these ribs that gives the kite its aerofoil shape and enable it to generate lift. The most common type is the ram-air foil, where each cell has a gauze-covered opening at the front, meaning air is forced in during flight, giving the kite its stiffness and enabling it to hold its profile. Some ram-air foils are closed-cell, where a one-way valve locks the air inside the cells, giving some increased water relaunch capability. Leading edge inflatable kites (LEIs) are made of a single skin of f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ballet
Ballet () is a type of performance dance that originated during the Italian Renaissance in the fifteenth century and later developed into a concert dance form in France and Russia. It has since become a widespread and highly technical form of dance with Glossary of ballet, its own vocabulary. Ballet has been influential globally and has defined the foundational ballet technique, techniques which are used in many other dance genres and cultures. Various schools around the world have incorporated their own cultures. As a result, ballet has evolved in distinct ways. A ''ballet'' as a unified work of art, work comprises the choreography (dance), choreography and music for a ballet production. Ballets are choreographed and performed by trained ballet dancers. Traditional classical ballets are usually performed with classical music accompaniment and use elaborate costumes and staging, whereas modern ballets are often performed in simple costumes and without elaborate sets or scenery ...

Sport Kites
A sport kite, also commonly known as a stunt kite, is a type of multiline kite that can be maneuvered in the air. A related kite, also controllable and used for recreation, but capable of generating a significant amount of pull and used for providing movement, is the power kite. Configuration One common configuration for a sport kite is a roughly triangular "delta" shape based on the Rogallo wing, with two lines for control. Another common configuration is a W-shaped panel based on the Hadzicki wing, with four lines for control. These kites are normally constructed from lightweight ripstop nylon or ripstop polyester with spars made from carbon fiber tubing. The flying lines are made from braided ultra-high-molecular-weight polyethylene, which is light, does not stretch under tension and stays slippery even when wrapped many times. Dual-line sport kites are controlled by the pilot adding and releasing tension on the right and left lines. A pilot may pull on the right-hand li ...
