From Wikipedia, the free encyclopedia

Hang glider commerce (including the sort of hang glider called paraglider) involves the matters that provide goods and services to people using hang gliders (which includes paraglider hang gliders); the commerce ranges over industrial contracts, retail, wholesale, repair, instruction, and the supply and selling of gear and instruments involved in the use of hang gliders; there is considerable selling and trading of used equipment with the appropriate cautions to verify the condition of traded goods for sake of safety.

Hang gliders are manned or unmanned gliders distinguished by having their dominant payload hanging substantially below the essential wing set; two major sorts occur: 1. the hanging payload solidly couples with the wing set, and 2. the hanging payload hangs from the wing using only tethers; these are gliding kites, i.e., paragliders. Sizes of hang gliders vary to fit purposes which includes toys, models, recreational and sport human-flown craft, robot-controlled versions, and large industrial flying machines.

Mechanically all paragliders are hang gliders; when a paraglider of single-tether allows the pilot to grab a wing's airframe for control, then the device is only rarely called paraglider, but is called hang glider. The hang gliders of Otto Lilienthal did not use tethers; he sold some hang gliders to others. In 1908 in Breslau in a gliding club: a hang glider of single tether hung the pilot behind a cable-stayed wing's triangle control frame; that arrangement examples the tethered-payload type of hang glider; a modern version of a single-tether-payloaded commercially sold hang glider is the Falcon 3 by the Wills Wing company[1]; their offers are evolutes of the Rogallo-inspired NASA paraglider technologies. Examples of commercially sold hang gliders of the paraglider sort are that feature in their wings evolutes of the Jalbert parafoil invention like in the contemporary Prymus 3 by the SOL company[2] in Brasil.
