Rokkaku Dako
The Rokkaku dako (六角凧) is a traditional six-sided Japanese fighter kite. Traditionally, it is made with bamboo spars and washi paper. The rokkaku kite is often hand painted with the face of a famous Samurai. The structure is a vertically stretched hexagon with a four-point bridle. One bamboo runs from tip to toe, and there are two cross-spars. Flown on a taut string, the kite is stable and rises rapidly. When the line is released, the kite tumbles until tension is put on the line, at which point it takes off in the direction of the spine. Fighting two or more of these kites involves tipping over or destabilizing the opposing kite or cutting its kite line or bridle. Cows are often painted on kites to resemble wealth. Stability can be increased by bowing the cross spars, making the kite stable enough to fly without a tail. The rokkaku kite is often used for kite aerial photography and in atmospheric science Atmospheric science is the study of the Atmosphere of Earth, Earth' ...

Fighter Kite
Fighter kites are kites used for the sport of kite fighting. Traditionally most are small, unstable single-line flat kites where line tension alone is used for control, at least part of which is manja, typically glass-coated cotton strands, to cut down the line of others. Kite fighting is contested in many countries, but particularly in Afghanistan, Bangladesh, India, Indonesia, Nepal, Pakistan, Vietnam, Korea, Thailand, Chile and Brazil. Materials In most traditional fighter kite manufacture, the skins of kites are made from a lightweight thin paper and the spars are usually made from a lightweight and flexible wood, usually bamboo. In modern American fighters, the kite skins are made from a variety of synthetic materials – mylar, aircraft insulation (orcon or insulfab), nylon, and polyester sheeting. The spine may still be bamboo, but often along with the bow is constructed of fiberglass or carbon fibre. Line Historically, for most Asian type fighters, a thin cotto ...

Bamboo
Bamboos are a diverse group of evergreen perennial flowering plants making up the subfamily Bambusoideae of the grass family Poaceae. Giant bamboos are the largest members of the grass family. The origin of the word "bamboo" is uncertain, but it probably comes from the Dutch or Portuguese language, which originally borrowed it from Malay or Kannada. In bamboo, as in other grasses, the internodal regions of the stem are usually hollow and the vascular bundles in the cross-section are scattered throughout the stem instead of in a cylindrical arrangement. The dicotyledonous woody xylem is also absent. The absence of secondary growth wood causes the stems of monocots, including the palms and large bamboos, to be columnar rather than tapering. Bamboos include some of the fastest-growing plants in the world, due to a unique rhizome-dependent system. Certain species of bamboo can grow within a 24-hour period, at a rate of almost an hour (equivalent to 1 mm every 90 seco ...

Washi
is traditional Japanese paper. The term is used to describe paper that uses local fiber, processed by hand and made in the traditional manner. ''Washi'' is made using fibers from the inner bark of the gampi tree, the mitsumata shrub (''Edgeworthia chrysantha''), or the paper mulberry (''kōzo'') bush. As a Japanese craft, it is registered as a UNESCO intangible cultural heritage. ''Washi'' is generally tougher than ordinary paper made from wood pulp, and is used in many traditional arts. Origami, Shodō, and Ukiyo-e were all produced using ''washi''. ''Washi'' was also used to make various everyday goods like clothes, household goods, and toys, as well as vestments and ritual objects for Shinto priests and statues of Buddha. It was even used to make wreaths that were given to winners in the 1998 Winter Paralympics. ''Washi'' is also used to repair historically valuable cultural properties, paintings, and books at museums and libraries around the world, such as the Louvre ...

Samurai
were the hereditary military nobility and officer caste of medieval and early-modern Japan from the late 12th century until their abolition in 1876. They were the well-paid retainers of the '' daimyo'' (the great feudal landholders). They had high prestige and special privileges such as wearing two swords and ''Kiri-sute gomen'' (right to kill anyone of a lower class in certain situations). They cultivated the '' bushido'' codes of martial virtues, indifference to pain, and unflinching loyalty, engaging in many local battles. Though they had predecessors in earlier military and administrative officers, the samurai truly emerged during the Kamakura shogunate, ruling from 1185 to 1333. They became the ruling political class, with significant power but also significant responsibility. During the 13th century, the samurai proved themselves as adept warriors against the invading Mongols. During the peaceful Edo period (1603 to 1868), they became the stewards and chamberlains of ...

Hexagon
In geometry, a hexagon (from Ancient Greek, Greek , , meaning "six", and , , meaning "corner, angle") is a six-sided polygon. The total of the internal angles of any simple polygon, simple (non-self-intersecting) hexagon is 720°. Regular hexagon A ''regular polygon, regular hexagon'' has Schläfli symbol and can also be constructed as a Truncation (geometry), truncated equilateral triangle, t, which alternates two types of edges. A regular hexagon is defined as a hexagon that is both equilateral polygon, equilateral and equiangular polygon, equiangular. It is bicentric polygon, bicentric, meaning that it is both cyclic polygon, cyclic (has a circumscribed circle) and tangential polygon, tangential (has an inscribed circle). The common length of the sides equals the radius of the circumscribed circle or circumcircle, which equals \tfrac times the apothem (radius of the inscribed figure, inscribed circle). All internal angles are 120 degree (angle), degrees. A regular hexago ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bowed Kite
Bowed kites such as the Japanese rokkaku, and traditional versions of the more familiar "diamond" shaped kites such as the Malay or Eddy, are tensioned into a bow in order to improve their stability to the point where a tail often becomes unnecessary. The classic long-tail diamond kite, with a simple two-point bridle, has its lateral roll or flutter (oscillation) greatly reduced or eliminated by a bow in its horizontal spar. Some modern designs use a fixed plastic joiner with a dihedral shape instead of a bowed spar to achieve the same stability effect. See also * Tetrahedral kite A tetrahedral kite is a multicelled rigid box kite composed of tetrahedrally shaped cells to create a kind of tetrahedral truss. The cells are usually arranged in such a way that the entire kite is also a regular tetrahedron. The kite can be desc ... References Bowed kites at the Virtual Kite Zoo.

Kite Aerial Photography
Kite aerial photography (KAP) is a type of photography. A camera is lifted using a kite and is triggered either remotely or automatically to take aerial photographs. The camera rigs can range from the extremely simple, consisting of a trigger mechanism with a disposable camera, to complex apparatus using radio control and digital cameras. On some occasions it can be a good alternative to other forms of aerial photography. Camera rig and stabilisation The camera can be attached directly to the kite but is usually secured to an adjustable rig suspended from the kite line at a distance from the kite. This distance reduces excessive movement being transmitted from the kite to the camera and allows the kite to be flown into higher, stable air before the camera is attached. If possible, the camera is set to a high shutter speed to reduce motion blur. Cameras using internal image stabilization features can increase the number of sharp photos. In order to take photographs that are orien ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atmospheric Science
Atmospheric science is the study of the Atmosphere of Earth, Earth's atmosphere and its various inner-working physical processes. Meteorology includes atmospheric chemistry and atmospheric physics with a major focus on weather forecasting. Climatology is the study of atmospheric changes (both long and short-term) that define average climates and their change over time, due to both natural and anthropogenic climate change, climate variability. Aeronomy is the study of the upper layers of the atmosphere, where dissociation (chemistry), dissociation and ionization are important. Atmospheric science has been extended to the field of planetary science and the study of the atmospheres of the planets and natural satellites of the Solar System. Experimental instruments used in atmospheric science include satellites, rocketsondes, radiosondes, weather balloons, radars, and lasers. The term aerology (from Ancient Greek, Greek ἀήρ, ''aēr'', "air"; and -λογία, ''-logy, -logia'') is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese Culture
The culture of Japan has changed greatly over the millennia, from the country's prehistoric Jōmon period, to its contemporary modern culture, which absorbs influences from Asia and other regions of the world. Historical overview The ancestry of Japanese people remains mysterious; however, there are two competing hypotheses that try to explain the lineage of the Japanese people. The first hypothesis proposes a dual-structure model, in which Japanese populations are descendants of the indigenous Jomon people and later arrivals of people from the East Eurasian continent, known as the Yayoi people. Japan's indigenous culture originates primarily from the Yayoi people who settled in Japan between 1000 BCE and 300 CE. Yayoi culture spread to the main island of Honshū, mixing with the native Jōmon culture. Modern Japanese have an estimated 80% Yayoi and 20% Jōmon ancestry. The second hypothesis posits a tripartite model of genomic origin. This hypothesis proposes that co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
