The arckite or twinskin kite is a type of traction kite designed and patented by Peter Lynn. It is a very stable, safe and secure type of powerkite. It can be used for all kinds of kite powered sports, for example: kiteboarding, landboarding, kite buggying or snowkiting. The shape of the kite is similar to a C shaped leading edge inflatable kite, however the construction is similar to a foil kite. These kites also fall into a category of foils called "closed-cell inflatables", meaning that the ram-air inlets on the leading edge of the kite are normally closed by flaps that act as one-way valves to maintain internal air pressure. It is this feature that makes the kite useful for kitesurfing since, unlike standard open-cell foils, if the kite crashes on the water, it will stay inflated and float long enough for the rider to recover and re-launch.
Peter Lynn is a New Zealand kitemaker, engineer and inventor. He is notable for his construction of the world's largest kites, giant inflatable (sparless) display kites, the popularisation of kite buggying and contributions to the development of power kiting and kitesurfing. He spends much of the year travelling worldwide and displaying his kites at International Kite Festivals.
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 and the Vake mini-expedition race. 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 is becoming increasingly popular in places often associated with skiing and snowboarding, such as Russia, Canada, Iceland, France, Switzerland, Austria, Norway, Sweden and the Northern and Central United States. The sport is becoming more diverse as adventurers use kites to travel great distances and sports enthusiasts push the boundaries of freestyle, big air, speed and back country exploration.
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. 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.
Depending on the specific style of the kite its suitable better for different usages, however, each of the kites can be used on all terrain.
Kites which are not as easy to water relaunch, but have better depower and upper wind range.

A kite is a tethered heavier-than-air craft with wing surfaces that react against the air to create lift and drag. 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. One technical definition is that a kite is “a collection of tether-coupled wing sets“.
A wing is a type of fin that produces lift, while moving through air or some other fluid. As such, wings have streamlined cross-sections that are subject to aerodynamic forces and act as an airfoils. A wing's aerodynamic efficiency is expressed as its lift-to-drag ratio. The lift a wing generates at a given speed and angle of attack can be one to two orders of magnitude greater than the total drag on the wing. A high lift-to-drag ratio requires a significantly smaller thrust to propel the wings through the air at sufficient lift.
Boardsports are sports that are played with some sort of board as the primary equipment. These sports take place on a variety of terrain, from paved flat-ground and snow-covered hills to water and air. Most boardsports are considered action sports or extreme sports, and thus often appeal to youth. A large proportion of youth partaking in these sports, together with aesthetic damage to property from sports like skateboarding, has led to many board sports being marginalized by the greater world of sports in the past. However, many board sports are ever-more frequently gaining mainstream recognition, and with this recognition have enjoyed wider broadcast, sponsorship and inclusion in institutional sporting events, including the Olympic Games.
A fixed-wing aircraft is a flying machine, such as an airplane or aeroplane, which is capable of flight using wings that generate lift caused by the aircraft's forward airspeed and the shape of the wings. Fixed-wing aircraft are distinct from rotary-wing aircraft, and ornithopters. The wings of a fixed-wing aircraft are not necessarily rigid; kites, hang gliders, variable-sweep wing aircraft and aeroplanes that use wing morphing are all examples of fixed-wing aircraft.
Kiteboarding is an action sport combining aspects of wakeboarding, snowboarding, windsurfing, surfing, paragliding, skateboarding and sailing into one extreme sport. A kiteboarder harnesses the power of the wind with a large controllable power kite to be propelled across the water, land, or snow.
A power kite or traction kite is a large kite designed to provide significant pull to the user.
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 structures employ the inflatable principle. Inflation occurs through several strategies: pumps, ram-air, billowing, and suction.
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.
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.
SkySails GmbH & Co. KG is a Hamburg-based company that sells kite rigs to propel cargo ships, large yachts and fishing vessels by wind energy. Ships are pulled by an automatically-controlled foil kite of some hundreds of square meters. For multiple reasons, they give many times the thrust per unit area of conventional mast-mounted sails.
Domina Jalbert (1904-1991) invented the ram-air inflated flexible wing often called the "Jalbert parafoil". Domina C. Jalbert.
Kites are tethered flying objects which fly by using aerodynamic lift, requiring wind for generation of airflow over the lifting surfaces.
The paravane is a towed winged (hydrofoiled) underwater object—a water kite. Paravanes have been used in sport or commercial fishing, marine exploration and industry, sports and military. The wings of paravanes are sometimes in a fixed position, else positioned remotely or by actions of a human pilot. Pioneer parafoil developer Domina Jalbert considered water kites hardly different from air kites. However, paravanes generally orient themselves in respect to the water surface. They may have sensors that record or transmit data or be used entirely for generating a holding force like a sea anchor does. While a sea-anchor allows a vessel to drift more slowly downwind, the paravane travels sideways at several times the downwind speed. Paravanes are, like air kites, often symmetrical in one axis and travel in two directions, the change being effected by gybing, shunting, or flipping over.
Supported leading edge kite (SLE) is a type of power kite used mainly for kitesurfing.
The wing configuration of a fixed-wing aircraft is its arrangement of lifting and related surfaces.
Imperatoxin I (IpTx) is a peptide toxin derived from the venom of the African scorpion Pandinus imperator.
Kite rigs are wind-assisted propulsion systems for propelling a vehicle. They differ from conventional sails in that they are flown from kite control lines, not supported by masts.
