Indoor Kite
Indoor kites are kites designed to fly in a windless environment. While principally designed for indoor use, they can also be flown outdoors when insufficient wind would render conventional kite-flying impossible. They are flown by using the relative wind provided by the motion of the kite-flier. This motion is typically generated by the user walking slowly, often walking backwards and in circular floor patterns, but it can also be achieved with suitable pulls along the kite lines with the pilot staying in place. As ultralight kite making materials became available indoor kites were developed from the idea of flying low-wind kites. Indoor kites come in all varieties, typically variations of sport kites and glider kites. Two-line and four-line indoor sport kites are capable of performing most of the same tricks and maneuvers as outdoor kites, as well as maneuvers only available without wind like full circles around the pilot. Indoor kites are often flown in time to music and in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Four Indoor Kites
4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. In mathematics Four is the smallest composite number, its proper divisors being and . Four is the sum and product of two with itself: 2 + 2 = 4 = 2 x 2, the only number b such that a + a = b = a x a, which also makes four the smallest squared prime number p^. In Knuth's up-arrow notation, , and so forth, for any number of up arrows. By consequence, four is the only square one more than a prime number, specifically three. The sum of the first four prime numbers two + three + five + seven is the only sum of four consecutive prime numbers that yields an odd prime number, seventeen, which is the fourth super-prime. Four lies between the first proper pair of twin primes, three and five, which are the first two Fermat primes, like seventeen, which is the third. On the other ...

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 ...

Kite Line
In kiting, a line is the string made of cotton, nylon, silk or wire, which connects the kite to the person operating it or an anchor. Kites have a set of wings, a set of anchors, and a set of lines coupling the wings with the anchors. Kite lines perform various roles: bridle, control, tug, or special duty. Successful kiting in particular kite applications depends in large part on the kite line's specifications and handling. The integrity of kite lines is affected by wear, reeling, contact with chemicals, loss of strength from knottings, ultraviolet rays of the sun, repeated cycles of use, and damaging actions during use. There are historically classic specifications of kite lines. Kite lines for small toy kites differ greatly from kite lines used for kite tugs that pull commercial cargo ships across the ocean. Sport kites using kite line sets of two or three or four lines at a time have a need for very low stretch in the lines. Single-line recreation kite lines may do well with str ...

Sport Kites
A sport kite, also commonly known as a stunt kite, is a type of 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 line to turn r ...

Kite Types
Kites are tethered flying objects which fly by using aerodynamic lift, requiring wind (or towing) for generation of airflow over the lifting surfaces. Various types of kites exist, depending on features such as material, shape, use, or operating skills required. Kites may fly in air, water, or other fluids such as gas and other liquid gaining lift through deflection of the supporting medium. Variations in design of tethering systems and lifting surfaces are regularly introduced, with lifting surfaces varying in stiffness from limp sheet material to fully solid material. Manufacture Kites may be built by the flier or by a dedicated kite manufacturer, which may be a member of the Kite Trade Association International (KTAI), which also includes kite retailers. Materials Kites have been made from the following materials: *Plastic – for example, a Styrofoam-only kite *Organic materials – such as plant leaves and grass *Paper *Textiles such as rip-stop nylon, nylon, or Dacron ...

Kite Applications
The kite can be used for many applications. Different kites such as water kites, bi-media kites, fluid kites, gas kites, kytoons, paravanes, soil kites, solid kites, and plasma kites have niche applications. Some animals, such as spiders, also make use of kiting. Aerial photography File:PicEddyKite.jpg, William Abner Eddy patented a kite. He used kites for aerial photography (KAP).

Rogallo Wing
The Rogallo wing is a flexible type of wing. In 1948, Francis Rogallo, a NASA engineer, and his wife Gertrude Rogallo, invented a self-inflating flexible wing they called the Parawing, also known after them as the "Rogallo Wing" and flexible wing. NASA considered Rogallo's flexible wing as an alternative recovery system for the Mercury and Gemini space capsules, and for possible use in other spacecraft landings, but the idea was dropped from Gemini in 1964 in favor of conventional parachutes. History Rogallo had been interested in the flexible wing since 1945. He and his wife built and flew kites as a hobby. They could not find official backing for the wing, including at Rogallo's employer National Advisory Committee for Aeronautics (NACA), so they carried out experiments in their own time. By the end of 1948 they had two working designs using a flexible wing — a kite they called "Flexi-Kite" and a gliding parachute they later referred to as a "paraglider". Rogallo and hi ...
