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.

Kite
A kite is a tethered heavier than air flight, heavier-than-air or lighter-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 don’t 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 kite (bird), kite, the hovering bird of prey. 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 or tethers to which t ...

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' ...

Dihedral Angle
A dihedral angle is the angle between two intersecting planes or half-planes. In chemistry, it is the clockwise angle between half-planes through two sets of three atoms, having two atoms in common. In solid geometry, it is defined as the union of a line and two half-planes that have this line as a common edge. In higher dimensions, a dihedral angle represents the angle between two hyperplanes. The planes of a flying machine are said to be at positive dihedral angle when both starboard and port main planes (commonly called wings) are upwardly inclined to the lateral axis. When downwardly inclined they are said to be at a negative dihedral angle. Mathematical background When the two intersecting planes are described in terms of Cartesian coordinates by the two equations : a_1 x + b_1 y + c_1 z + d_1 = 0 :a_2 x + b_2 y + c_2 z + d_2 = 0 the dihedral angle, \varphi between them is given by: :\cos \varphi = \frac and satisfies 0\le \varphi \le \pi/2.

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 described as a compound dihedral kite as well. This kite was invented by Alexander Graham Bell. It came about from his experiments with Hargrave's box kites and his attempts to build a kite that was scalable and big enough to carry both a man and a motor. As such, it was an early experiment on the road to manned flight. He worked on the kites between 1895 and 1910. Bell wrote about his discovery of this concept in the June 1903 issue of ''National Geographic'' magazine; the article was titled "Tetrahedral Principle in Kite Structure". From an initial one-cell model, Bell advanced to a 3,393-cell " Cygnet" model in 1907. This 40-foot-long (12.2 m), 200-pound (91 kilogram) kite was towed by a steamer offshore near Baddeck, Nova Scotia, on Dec ...
