The glide ratio of paragliders ranges from

9.3 for recreational wings to about 11.3 for modern competition models,[16]

reaching in some cases up to 13.[17] For comparison, a typical skydiving

parachute will achieve about 3:1 glide. A hang glider ranges from 9.5 for

recreational wings to about 16.5 for modern competition models. An idling

(gliding) Cessna 152 light aircraft will achieve 9:1. Some sailplanes can

achieve a glide ratio of up to 72:1.

The speed range of paragliders is typically

20–75 kilometres per hour (12–47 mph), from stall speed to maximum speed.

Beginner wings will be in the lower part of this range, high-performance wings

in the upper part of the range.[note 2]

For storage and carrying, the wing is

usually folded into a stuffsack (bag), which can then be stowed in a large

backpack along with the harness. For pilots who may not want the added weight

or fuss of a backpack, some modern harnesses include the ability to turn the

harness inside out such that it becomes a backpack.

大约在那个时候，大卫·巴里什（David Barish）正在开发用于恢复NASA太空舱的“帆翼”（单面翼）-“高耸的斜坡是一种测试……帆翼的方法。” 在对Hunter进行测试之后1965年9月，他在纽约的山上继续推广滑雪胜地的夏季活动[6] [7]。

作者Walter Neumark撰写了《降落伞操作程序》，并于1973年与一群对拖曳PC和ram-air降落伞充满热情的爱好者脱离了英国降落伞协会，成立了英国降落伞俱乐部协会（此协会后来成为英国的滑翔伞和滑翔伞协会）。 1997年，纽马克（Neumark）被英国皇家航空俱乐部（Royal Aero Club）授予奖牌。作家Patrick Gilligan（加拿大）和Bertrand Dubuis（瑞士）于1985年撰写了首本飞行手册《滑翔伞手册》，创造了滑翔伞一词。

1978年6月，来自法国上萨瓦省Mieussy的三个朋友Jean-ClaudeBétemps，AndréBohn和GérardBosson将这些发展合并在一起。在跳伞者和发行人丹·波因特（Dan Poynter）在《降落伞手册》杂志上发表的一篇有关坡度飞涨的文章的灵感启发之后，[7]他们计算出，在合适的坡度上，可以通过顺着坡道向“方形”的冲压空气降落伞充气； Bétemps从Mieussy的Pointe du Pertuiset发射升空100 m。博恩跟随他，滑到1000米以下山谷的足球场。

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。

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]

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.

Europe has seen the greatest growth in

paragliding, with France alone registering in 2011 over 25,000 active pilots.

Cross section of a paraglider

Transverse cross section showing parts of a

paraglider:

1) upper surface

2) lower surface

3) rib

4) diagonal rib

5) upper line cascade

6) middle line cascade

7) lower line cascade

8) risers

The paraglider wing or canopy is usually

what is known in engineering as a "ram-air airfoil". Such wings

comprise two layers of fabric that are connected to internal supporting

material in such a way as to form a row of cells. By leaving most of the cells

open only at the leading edge, incoming air keeps the wing inflated, thus

maintaining its shape. When inflated, the wing's cross-section has the typical

teardrop aerofoil shape. Modern paraglider wings are made of high-performance

non-porous materials such as ripstop polyester[12] or nylon fabric.[note 1]
