A windsport is any type of sport which involves wind-power, often involving a non-rigid airfoil such as a sail or a power kite. The activities can be land-based, on snow, on ice or on water. Windsport activity may be regulated in some countries by aviation/maritime authorities if they are likely to interfere with other activities.
The wind window is the 180 degree arc of the sky downwind of the rider in which the kite can be flown - roughly one fourth of a sphere's surface, which radius is the length of the lines. It is the atmosphere volume in which the kiter can navigate the kite to harvest wind energy.
Crosswind kite power is power derived from airborne wind-energy conversion systems (AWECS, also AWES) or crosswind kite power systems (CWKPS). The kite system is characterized by energy-harvesting parts flying transversely to the direction of the ambient wind, i.e., to crosswind mode; sometimes the entire wing set and tether set are flown in crosswind mode.
Wind shear, sometimes referred to as wind gradient, is a difference in wind speed and direction over a relatively short distance in the Earth's atmosphere. [61] Wind shear can be broken down into vertical and horizontal components, with horizontal wind shear seen across weather fronts and near the coast, [62] and vertical shear typically near ...
Airborne wind energy (AWE) is the direct use or generation of wind energy by the use of aerodynamic or aerostatic lift devices. AWE technology is able to harvest high altitude winds , in contrast to wind turbines , which use a rotor mounted on a tower.
Gliding is a recreational activity and competitive air sport [1] in which pilots fly unpowered aircraft known as gliders or sailplanes using naturally occurring currents of rising air in the atmosphere to remain airborne. The word soaring is also used for the sport. [2] Gliding as a sport began in the 1920s.
A difference in air pressure causes an air displacement and generates the wind. The Coriolis force deflects the air movement to the right in the northern hemisphere and the left in the southern one, which makes the winds parallel to the isobars on an elevation in pressure card. [1] It is also referred as the geostrophic wind. [2]
Wind turbine – a turbine that converts wind energy into mechanical energy. Windmill – a machine which converts the energy of wind into rotational energy by means of vanes called sails or blades. Windpump – a windmill used for pumping water, either as a source of fresh water from wells, or for draining low-lying areas of land.
