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 Kössen, Austria, in
1989.[10]

滑翔伞完整的设备打包成背包,可以轻松地放在飞行员的后背,汽车或公共交通工具上。[14]与其他航空运动相比,这**简化了到达合适起飞点的行程,着陆地点的选择和返程行程。
双人滑翔伞设计用来载飞行员和一名乘客,虽然较大,但在其他方面相似。与单独的滑翔伞相比,它们通常以更高的修剪速度飞行得更快,更不易塌陷,并且下沉率略高。
带线束的飞行员(浅蓝色),进行反向发射
飞行员可以轻松舒适地扣入安全带,该安全带可在站立和坐姿中提供支撑。大多数安全带在座椅下方和后方都有泡沫或安全气囊保护装置,以减少对失败的发射或着陆造成的影响。现代安全带的设计使其在坐姿或躺姿时都像躺椅一样舒适。许多背带甚至具有可调节的“腰部支撑”。备用降落伞通常也连接至滑翔伞背带。
线束也根据飞行员的需求而有所不同,因此设计范围很广,主要是:初学者的训练用安全带,双人旅客的Pax防护带(通常还兼用作训练用安全带),长距离越野飞行的XC线束, Pod线束,适用于基本至中级飞行员的全能线束,适用于专注于XC的中级至专业飞行员。杂技安全带是专为杂技飞行员设计的,儿童双人安全带现在也提供特殊的儿童防盗锁。

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).
Launching

As with all aircraft, launching and landing
are done into wind. The wing is placed into an airstream, either by running or
being pulled, or an existing wind. The wing moves up over the pilot into a
position in which it can carry the passenger. The pilot is then lifted from the
ground and, after a safety period, can sit down into his harness. Unlike
skydivers, paragliders, like hang gliders, do not "jump" at any time
during this process. There are two launching techniques used on higher
ground[20] and one assisted launch technique used in flatland areas:
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.

SIV是模拟d'Incident en Vol(飞行中的事件模拟)的缩写,是提供有关如何应对不稳定和潜在危险情况(例如倒塌,满是失速和开裂)的课程。这些课程通常由经过特殊培训的讲师在大片水域上讲授,通常通过无线电指导学生。将指导学生如何诱发危险情况,从而学习一旦被诱发就如何避免和补救。向希望获得更高性能和更不稳定机翼的飞行员推荐该课程,这对于大多数飞行员而言都是自然而然的进步。在某些国家,SIV课程是初步飞行员培训的基本要求。万一出现无法挽回的机动导致水着陆的情况,通常会派出一艘救援船来收集飞行员。其他增加的安全功能可能包括浮力辅助装置或辅助备用降落伞。这些课程对于新手级别的飞行不是必不可少的。
