Europe has seen the greatest growth in

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

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]

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.

热飞行

托里·派恩斯滑翔伞在空中滑翔伞

当太阳温暖地面时，它将使某些功能比其他功能（例如岩石表面或大型建筑物）加热得更多，而这些功能会引发通过空气上升的热量。有时，这些可能只是空气的简单上升；通常，它们在风中向侧面吹，会从源头脱落，随后形成新的热量。

一旦飞行员找到了热量，他便开始绕圈飞行，试图将圆圈定位在热量**强的部分（“**”）上，其中空气的上升**快。大多数飞行员使用可变高度计（“ vario”），通过嘟嘟声和/或视觉显示来指示爬升率，以帮助将热量插入磁芯中。

通常情况下，周围的热源周围有很强的水槽，当飞行员试图进入强热源时，也存在强烈的湍流，导致机翼塌陷。良好的热力飞行是一项需要花费时间学习的技能，但是好的飞行员通常可以将热力一直贯穿到整个云层。

越野飞行

一旦掌握了使用热量来获得高度的技巧，飞行员就可以从一个热量滑到另一个热量来穿越国家。在热量中获得高度后，飞行员会下滑到下一个可用热量。

潜在的热量可以通过通常会产生热量的陆地特征或积云来识别，这些积云标志着上升的一列温暖，潮湿的空气在到达**并凝结成云时的顶部。

越野飞行员还需要熟悉航空法律，飞行法规，指示空域受限的航空地图等。

安全

像任何极限运动一样，滑翔伞是一种潜在的危险活动。例如，在美国，2010年，一名滑翔伞飞行员死亡。这相当于5,000名飞行员中的一名。在1994-2010年间，每10,000名活跃的滑翔伞飞行员中平均有7人受到致命伤害，尽管近年来情况已有明显改善。在法国（有超过25,000名注册机员），2011年每10,000名飞行员中有2人受伤（这一比率并非2007-2011年的非典型），尽管每1,000名飞行员中约有6人受到严重伤害（超过2名飞行员，日间住院）。

通过培训和风险管理可以**减少伤害的可能性。使用适当的设备，例如为飞行员的身材和技能水平设计的机翼[28]，以及头盔，备用降落伞[29]和缓冲式安全带[30]，也可以很大程度地降低风险。飞行员的安全受到对现场条件（如空气湍流（转子），强热，狂风和地面障碍物，如电力线）的了解的影响。胜任的教练对机翼控制和紧急演习进行足够的飞行员培训可以很大程度地减少。许多滑翔伞是飞行员错误和飞行条件差的结果。

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]

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).
