Leading Edge Inflatable Kite
A leading edge inflatable kite (LEI) is a single skin kite with inflatable bladders providing structure. It is useful as a power or traction kite. These kites are flown using 2, 4 or 5 control lines and a bar. (See also: kite control systems) A LEI is a great kite for water use because the inflated bladders cause it to float on the water surface. A LEI can sit on the water for an indefinite time and still be relaunched because, unlike a foil kite, there are no chambers that can fill with water. Generally used for kitesurfing and kiteboarding, leading edge inflatable kites come in many different sizes, most commonly from 5 to 18 square metres. Based on their design Leading Edge Inflatable kites can be broken down into four categories: C-kites, hybrid kites, delta kites, and bow kites. C-kites C-kites are the oldest style of LEI used for traction kiting. They typically come with four lines, and some have the option of an additional 5th line for safety and easy relaunching. Th ...

Kite Flying
A kite is a tethered heavier-than-air or lighter-than-air craft with wing surfaces that react against the air to create lift and 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, the hovering bird of prey. The 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 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 lines or tethers to which the kite is attached. The anchor point of the kite line may be static or moving (e.g., the towing of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Inflatable Kite
An inflatable is an object that can be inflated with a gas, usually with air, but hydrogen, helium and nitrogen are also used. One of several advantages of an inflatable is that it can be stored in a small space when not inflated, since inflatables depend on the presence of a gas to maintain their size and shape. Function fulfillment per mass used compared with non-inflatable strategies is a key advantage. Stadium cushions, impact guards, vehicle wheel inner tubes, emergency air bags, and inflatable space habitats employ the inflatable principle. Inflation occurs through several strategies: pumps, ram-air, blowing, and suction. Although the term ''inflatable'' can refer to any type of inflatable object, the term is often used in boating to specifically refer to inflatable boats. Types High-pressure vs. low-pressure A distinction is made between high-pressure and low-pressure inflatables. In a high-pressure inflatable, structural limbs like pillars and arches are built out ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kite Control Systems
Kite types, kite mooring, and kite applications result in a wide variety of kite control systems. Contemporary manufacturers, kite athletes, kite pilots, scientists, and engineers are expanding the possibilities. Single-line kite control systems High-altitude attempt single-line control systems On-board angle-of-attack mechanisms were used in the 2000 altitude record-making flight; the operators' designed adjuster limited kite line tension to not more than 100 pounds by altering the angle of attack of the kite's wing body. The kite's line had a control: a line payout meter that did not function in the record-setting flight. However, some special tether line lower end used bungee and pulley arrangements to lower the impact of gusts on the long tether. Control of a kite includes how other aircraft see the kite system; the team placed a radio beacon (using two-meter frequency detectable for 50 miles) on the kite; for sight visibility, strobe lights were hung from the kite's nose. ...

Foil Kite
Foil kites are soft kites based on the design of the parafoil. They consist of a number of cells running fore to aft, some or all of which are open at the front to allow air to inflate the kite so it takes on an aerofoil section. Due to the amount of power that these kites can generate, they can be used for a variety of different activities including kitesurfing, kite landboarding, snowkiting, kite buggying, kite-energy systems or airborne wind energy, and recreational kiting. Foil kites are flown with various line set-ups that includes 2-, 3- and 4-line systems; 2-line systems consisting of rings, wrist bands or bar compared to depowerable 4-line systems using a bar or handles. (See also: kite control systems) In order to make them suitable for use on water some foils have limited air inlets in the centre of the leading edge, with valves to keep the air in and (hopefully) the water out. Internal holes in the cell sides allow the whole kite to inflate. These kites are naturally s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kitesurfing
Kiteboarding or kitesurfing is a sport that involves using wind power with a large power kite to pull a rider across a water, land, or snow surface. It combines aspects of paragliding, surfing, windsurfing, skateboarding, snowboarding, and wakeboarding. Kiteboarding is among the less expensive and the more convenient sailing sports. After some concepts emerged in the late 1970s and early 1980s and some designs 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 kites or foil kites attached by about of flying lines to a control bar and a harness. The kitesurfer rides on either a bidir ...

Bow Kite
Bow kites are leading edge inflatable kites that incorporate a bridle on the leading edge. They are used for the sport of kiteboarding. They can be identified by a flat, swept-back profile and concave trailing edge allowing the kite greater depower. Bow kite design was pioneered by Bruno Legaignoux, and have been licensed to many kite manufacturers. The first major manufacturer to introduce these bow kites to the United States was Cabrinha Kites. Bow kites have a wider wind range than C-kites (traditional LEI kites), so two kite sizes (such 7m² and 12m²) could form an effective quiver for winds ranging from 10 to 30+ knots for a 75 kg rider. This makes bow kites more suitable for beginners to kite s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
