Land-based practice: Kiting
About 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 ... the Sail
Wing."[5] After tests on Hunter Mountain, New York, in September 1965, he
went on to promote slope soaring as a summer activity for ski resorts.[6][7]
Author Walter Neumark wrote Operating
Procedures for Ascending Parachutes, and in 1973 he and a group of enthusiasts
with a passion for tow-launching PCs and ram-air parachutes broke away from the
British Parachute Association to form the British Association of Parascending Clubs
(which later became the British Hang Gliding and Paragliding Association). In
1997, Neumark was awarded the Gold Medal of the Royal Aero Club of the UK.
Authors Patrick Gilligan (Canada) and Bertrand Dubuis (Switzerland) wrote the
first flight manual, The Paragliding Manual in 1985, coining the word
paragliding.

These developments were combined in June
1978 by three friends, Jean-Claude Bétemps, André Bohn and Gérard Bosson, from
Mieussy, Haute-Savoie, France. After inspiration from an article on slope
soaring in the Parachute Manual magazine by parachutist and publisher Dan
Poynter,[7] they calculated that on a suitable slope, a "square"
ram-air parachute could be inflated by running down the slope; Bétemps launched
from Pointe du Pertuiset, Mieussy, and flew 100 m. Bohn followed him and glided
down to the football pitch in the valley 1000 metres below.[8]
"Parapente" (pente being French for "slope") was born.
From the 1980s, equipment has continued to
improve, and the number of paragliding pilots and established sites has
continued to increase. The first (unofficial) Paragliding World Championship
was held in Verbier, Switzerland, in 1987,[9] though the first officially
sanctioned FAI World Paragliding Championship was held in K?ssen, Austria, in
1989.[10]

Paragliding is the recreational and competitive adventure sport of flying paragliders: lightweight, free-flying,
foot-launched glider aircraft with no rigid primary structure.[1] The pilot sits in a harness suspended below a fabric wing. 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.
Despite not using an engine, paragliderflights can last many hours and cover many hundreds of kilometres, though flights of one to two hours and covering some tens of kilometres are more the norm. By skillful exploitation of sources of lift, the pilot may gain height,
often climbing to altitudes of a few thousand metres.
滑翔傘是一批熱愛跳傘、滑翔翼的飛行人員發(fā)明的一種飛行運(yùn)動(dòng)，目前在歐美和日本等國(guó)非常流行，在中國(guó)臺(tái)灣也掀起了一股旋風(fēng)?；鑲闩c傳統(tǒng)的降落傘不同，它是一種飛行器。很久以前，人類為尋找一雙翅膀作過(guò)無(wú)數(shù)次的思考和探索。在古老的中國(guó)大地上，留下了像“駕車遨游太空”、“嫦娥奔月”等許多關(guān)于人類嘗試飛行的美好傳說(shuō)。當(dāng)今，滑翔傘的誕生，為人類插上了飛翔的翅膀。人們自由地翱翔于天空，享受著“脫離”地球引力的寧?kù)o與美妙.滑翔傘起源于20世紀(jì)70年代初的歐洲，當(dāng)時(shí)，一些登山者從山上乘降落傘滑翔而**驗(yàn)到了一種美好的感覺和樂(lè)趣，從而創(chuàng)立了一個(gè)新興的航空體育項(xiàng)目。**初的滑翔傘是借鑒于飛機(jī)跳傘使用的翼型方傘，它主要以下降為主，下降速度快，安全性能好。通過(guò)二十多年的發(fā)展和演變。現(xiàn)在的滑翔傘**長(zhǎng)飛行17小時(shí)，**遠(yuǎn)飛行距離超過(guò)300公里，它體現(xiàn)了一種人與自然的交流，備受崇尚自然者的喜愛。
The top of each line is attached to small
fabric loops sewn into the structure of the wing, which are generally arranged
in rows running span-wise (i.e., side to side). The row of lines nearest the
front are known as the A lines, the next row back the B lines, and so on.[14] A
typical wing will have A, B, C and D lines, but recently, there has been a
tendency to reduce the rows of lines to three, or even two (and experimentally
to one), to reduce drag.
Paraglider lines are usually made from
Dyneema/Spectra or Kevlar/Aramid.[14] Although they look rather slender, these
materials are immensely strong. For example, a single 0.66 mm-diameter line
(about the thinnest used) can have a breaking strength of 56 kg.[15]
Paraglider wings typically have an area of
20–35 square metres (220–380 sq ft) with a span of 8–12 metres (26–39 ft) and
weigh 3–7 kilograms (6.6–15.4 lb). Combined weight of wing, harness, reserve,
instruments, helmet, etc. is around 12–22 kilograms (26–49 lb).

In some modern paragliders (from the 1990s
onwards), especially higher-performance wings, some of the cells of the leading
edge are closed to form a cleaner aerodynamic profile. Holes in the internal
ribs allow a free flow of air from the open cells to these closed cells to
inflate them, and also to the wingtips, which are also closed.[13]
The pilot is supported underneath the wing
by a network of suspension lines. These start with two sets of risers made of
short (40 cm) lengths of strong webbing. Each set is attached to the harness by
a carabiner, one on each side of the pilot, and each riser of a set is generally
attached to lines from only one row of its side of wing. At the end of each
riser of the set, there is a small delta maillon with a number (2 – 5) of lines
attached, forming a fan. These are typically 4 – 5 metres long, with the end
attached to 2 ? 4 further lines of around 2 m, which are again joined to a
group of smaller, thinner lines. In some cases this is repeated for a fourth
cascade.
