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]

Radio
Radio communications are used in training,
to communicate with other pilots, and to report where and when they intend to
land. These radios normally operate on a range of frequencies in different
countries—some authorised,[18][19] some illegal but tolerated locally. Some
local authorities (e.g., flight clubs) offer periodic automated weather updates
on these frequencies. In rare cases, pilots use radios to talk to airport
control towers or air traffic controllers. Many pilots carry a cell phone so
they can call for pickup should they land away from their intended point of
destination.
GPS
GPS (global positioning system) is a
necessary accessory when flying competitions, where it has to be demonstrated
that way-points have been correctly passed. The recorded GPS track of a flight
can be used to analyze flying technique or can be shared with other pilots. GPS
is also used to determine drift due to the prevailing wind when flying at
altitude, providing position information to allow restricted airspace to be
avoided and identifying one's location for retrieval teams after landing out in
unfamiliar territory. 苏州**滑翔伞厂家报价
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.

与所有飞机一样，发射和降落都是在风中完成的。机翼通过奔跑或被拉动或存在的风被置于气流中。机翼在飞行员上方向上移动到可以运载乘客的位置。然后将飞行员从地面抬起，经过一段安全时期后，可以坐在他的安全带中。与跳伞运动员不同，滑翔伞与悬挂式滑翔伞一样，在此过程中不会随时“跳”起来。在高地上使用了两种发射技术[20]，在平地地区使用了一种辅助发射技术：
向前发射
在低风中，机翼通过向前发射而膨胀，飞行员在前进时将机翼向后移动，以便向前运动产生的气压使机翼膨胀。
这通常更容易，因为飞行员只需要向前跑，但是飞行员直到机翼上方都看不到他的机翼为止，在那里他必须在很短的时间内检查一下机翼，以确保发射前有正确的充气和不纠缠的线。

每条线的顶部连接到缝在机翼结构中的小织物线圈上，这些织物线圈通常成行排列（即，左右）。**靠近前一行的行称为A线，下一行称为B线，依此类推。典型的机翼将具有A，B，C和D线，但是**近，有一种趋势是将行的行数减少到三行，甚至两行（并从实验上减少到一行），以减少阻力。
滑翔伞线通常由迪尼玛/光谱或凯夫拉尔/芳纶制成。尽管它们看起来很苗条，但这些材料非常坚固。例如，一条直径为0.66毫的线（大约**细）可以具有56千克的断裂强度。
滑翔伞的滑翔率范围从休闲机翼的9.3到现代竞赛模型的约11.3，在某些情况下高达13。为了进行比较，典型的跳伞降落伞将实现约3：1的滑行。悬挂式滑翔机的范围从休闲机翼的9.5到现代竞赛机型的约16.5。空转（滑行）的塞斯纳152轻型飞机将达到9：1。一些滑翔机可以实现高达72：1的滑行比。
滑翔伞的速度范围通常为每小时20-75公里（12-47英里/小时），从失速速度到比较大速度。初学者机翼将位于该范围的下部，高性能机翼将位于该范围的上部。
为了存放和携带，机翼通常被折叠成一个行李袋，然后可以与安全带一起存放在一个大背包中。对于可能不希望增加背包重量或烦恼的飞行员，一些现代安全带具有将安全带内翻的功能，从而使其成为背包。
