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.

Europe has seen the greatest growth in

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

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]

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:

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。

滑翔伞驾驶员认证指导计划有几个关键组成部分。对初学者的初步培训通常从一定数量的地面学校开始，以讨论基础知识，包括基本的飞行理论以及滑翔伞的基本结构和操作。

然后，学生将学习如何在地面上控制滑翔机，练习起飞并控制机翼“高架”。接下来是低矮平缓的山丘，学生们可以在低空飞行，以习惯于在各种地形上操纵机翼。在没有丘陵的地区，可以使用特殊的绞车将滑翔机拖至低空。

随着技能的进步，学生们将进入更陡峭/更高的山丘（或更高的绞车拖曳），进行更长的飞行，并学习转动滑翔机，控制滑翔机的速度，然后继续进行360°转弯，点着陆，“大耳朵”

（用于增加滑翔伞的下降速度）和其他更先进的技术。通常通过无线电向学生提供培训说明，尤其是在首飞期间。

完整的滑翔伞教学计划的第三个关键要素是气象，航空法和一般飞行区礼节等关键领域的基本知识。

为了使准飞行员有机会确定他们是否愿意继续进行完整的飞行员培训计划，大多数学校都提供串联飞行，其中经验丰富的教练以准飞行员为乘客驾驶滑翔伞。学校通常会为飞行员的家人和朋友提供乘搭双人飞机的机会，有时还会在度假胜地出售乘搭双人飞机的乐趣。

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]
