Hang gliding is an air sport or recreational activity in which a pilot flies a light, non-motorised foot-launched heavier-than-air aircraft called a hang glider. Most modern hang gliders are made of an aluminium alloy or composite frame covered with synthetic sailcloth to form a wing. Typically the pilot is in a harness suspended from the airframe, and controls the aircraft by shifting body weight in opposition to a control frame.
Parasailing, also known as parascending, paraskiing orparakiting, is a recreational kiting activity where a person is towed behind a vehicle while attached to a specially designed canopy wing that resembles a parachute, known as a parasail wing. The manned kite's moving anchor may be a car, truck, or boat. The harness attaches the occupant to the parasail, which is connected to the boat, or land vehicle, by the tow rope. The vehicle then drives off, carrying the parascender and person into the air. If the boat is powerful enough, two or three people can parasail behind it at the same time. The parascender has little or no control over the parachute. The activity is primarily a fun ride, not to be confused with the sport of paragliding.
A wing is a type of fin that produces lift while moving through air or some other fluid. Accordingly, wings have streamlined cross-sections that are subject to aerodynamic forces and act as 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 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 heavier-than-air flying machine, such as an airplane, 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 airplanes that use wing morphing are all examples of fixed-wing aircraft.
Kiteboarding or kitesurfing is an extreme sport where the kiter uses the wind power with a large power kite to be pulled on 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 of the sailing sports.
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.
A power kite or traction kite is a large kite designed to provide significant pull to the user.
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.
A kite buggy is a light, purpose-built vehicle powered by a traction kite. It is single-seated and has one steerable front wheel and two fixed rear wheels. The driver sits in the seat located in the middle of the vehicle and accelerates and slows down by applying steering manoeuvres in coordination with flying manoeuvres of the kite. This activity is called kite buggying. The speed achieved in kite buggies by skilled drivers can range up to around 110 km/h (70 mph), hence protective clothing, including a safety helmet, is commonly worn.
A parafoil is a nonrigid (textile) airfoil with an aerodynamic cell structure which is inflated by the wind. Ram-air inflation forces the parafoil into a classic wing cross-section. Parafoils are most commonly constructed out of ripstop nylon.
The term "air sports" covers a range of aerial activities, including air racing, aerobatics, aeromodelling, hang gliding, human powered aircraft, parachuting, paragliding and skydiving.
A glider is a fixed-wing aircraft that is supported in flight by the dynamic reaction of the air against its lifting surfaces, and whose free flight does not depend on an engine. Most gliders do not have an engine, although motor-gliders have small engines for extending their flight when necessary by sustaining the altitude with some being powerful enough to take off by self-launch.
The kite can be used for many applications. Air kites, water kites, bi-media kites, fluid kites, gas kites, kytoons, paravanes, soil kites, solid kites, and plasma kites have niche applications that are furthering the interests of humans in both peace and conflict. Some animals, such as spiders, also make use of kiting.
Kites are tethered flying objects which fly by using aerodynamic lift, requiring wind for generation of airflow over the lifting surfaces.
Wind-powered vehicles derive their power from sails, kites or rotors and ride on wheels—which may be linked to a wind-powered rotor—or runners. Whether powered by sail, kite or rotor, these vehicles share a common trait: As the vehicle increases in speed, the advancing airfoil encounters an increasing apparent wind at an angle of attack that is increasingly smaller. At the same time, such vehicles are subject to relatively low forward resistance, compared with traditional sailing craft. As a result, such vehicles are often capable of speeds exceeding that of the wind.
Unpowered flight is the ability to stay airborne for a period of time without using any power source. There are several types of unpowered flight. Some have been exploited by nature, others by humankind, and some by both.
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.
