the Sail Wing." After tests on Hunter Mountain, New York, in September 1965, he went on to promote slope soaring as a summer activity for ski resorts. Paragliding with instructor over Lake Sils St Moritz (approx 3,000 m (9,800 ft)) 2018Ībout that time, David Barish was developing the sail wing (single-surface wing) for recovery of NASA space capsules-"slope soaring was a way of testing out. More particularly the invention contemplates the provision of a wing of rectangular or other shape having a canopy or top skin and a lower spaced apart bottom skin", a governable gliding parachute with multi-cells and controls for glide. In 1966, Canadian Domina Jalbert was granted a patent for a multi-cell wing type aerial device-"a wing having a flexible canopy constituting an upper skin and with a plurality of longitudinally extending ribs forming in effect a wing corresponding to an airplane wing airfoil. By skillful exploitation of sources of lift, the pilot may gain height, often climbing to altitudes of a few thousand metres. Wing shape is maintained by the suspension lines, the pressure of air entering vents in the front of the wing, and the aerodynamic forces of the air flowing over the outside.ĭespite not using an engine, paraglider flights can last many hours and cover many hundreds of kilometres, though flights of one to five hours and covering some tens of kilometres are more the norm. The pilot sits in a harness or lies prone in a cocoon-like 'pod' suspended below a fabric wing. Paragliding is the recreational and competitive adventure sport of flying paragliders: lightweight, free-flying, foot-launched glider aircraft with no rigid primary structure.
