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).

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.

在亚洲，日本、韩国、中国的中国台湾省等经济发达国家和地区的滑翔伞运动十分普及，爱好者达十多万人。20世纪80年代末，滑翔伞运动传入中国大陆并迅速发展，

现注册的航空俱乐部有50多个，正式会员1400多人，经常从事滑翔伞飞行者达数千人，在中国东北、长三角、珠三角长期有民间高手飞行，随着滑翔伞运动的逐渐普及，包括央视在内的很多电视媒体都对这一运动进行过专题报道。

滑翔伞通常主要由翼型伞衣、伞绳、背带系统和操纵系统四大部分组成。为便于滑翔伞的保管、携带与运输，每具滑翔伞还配有一只背式包装袋。

翼型伞衣，也称伞翼，是滑翔伞产生升力和承受载荷的主要部件。伞衣的形状、面积以及与气流相对运动的速度，对升力的产生有很大的影响。

翼型伞衣由上翼面、下翼面和沿翼展方向有规律分布的数十个成形翼肋构成。上下翼面与翼肋缝合，形成特定的伞翼形状。伞衣前缘按照翼肋的横向排列，构成一定尺寸的进气口。由于伞衣后缘是完全封闭的，所以上下翼面与各翼肋之间便形成了一个个用于储存空气的气室。

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。

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:

This can be very dangerous, because now the

forces on the line have to be controlled by the moving object itself, which is

almost impossible to do, unless stretchy rope and a pressure/tension meter

(dynamometer) is used. Static line towing with stretchy rope and a load cell as

a tension meter has been used in Poland, Ukraine, Russia, and other Eastern

European countries for over twenty years (under the name Malinka) with about

the same safety record as other forms of towing.[21] One more form of towing is

hand towing. This is where 1−3 people pull a paraglider using a tow rope of up

to 500 feet. The stronger the wind, the fewer people are needed for a

successful hand tow.[22] Tows up to 300 feet have been accomplished, allowing

the pilot to get into a lift band of a nearby ridge or row of buildings and

ridge-soar in the lift the same way as with a regular foot launch.[23]
