滑翔伞是飞行滑翔伞的娱乐和竞争性冒险运动：轻巧，自由飞行，脚踩滑翔机，没有刚性的基本结构[1]。

飞行员坐在悬挂在机翼下方的安全带中。

悬挂线，进入机翼前部通风孔的空气压力以及流过外部的空气的空气动力保持了机翼的形状。

尽管不使用发动机，滑翔伞飞行仍可持续数小时，飞行数百公里，尽管更常见的是飞行一到两个小时，飞行数十公里。

通过熟练地利用升力源，飞行员可以增加身高，通常会爬升到几千米的高度。

1954年，沃尔特·纽马克（Walter

Neumark）预测（在《飞行》杂志上的一篇文章），滑翔机飞行员“能够通过在悬崖边缘或斜坡上奔跑来发动自己……无论是在美国的攀岩假期中，

斯凯岛或阿尔卑斯山滑雪。”

1961年，法国工程师Pierre Lemongine制作了改进的降落伞设计，从而设计了Para-Commander。 PC的后部和侧面均设有切口，可将其拖入空中并进行操纵，从而实现滑翔伞运动。

多米娜·贾伯特（Domina Jalbert）发明了Parafoil，它具有呈翼型形状的切片细胞。 敞开式前缘和封闭式后缘，通过空气而膨胀-冲压空气设计。 他于1963年1月10日提交了美国专利3131894。 无锡进口滑翔伞便宜

Europe has seen the greatest growth in

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

Wing

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]

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。

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).

Forward launch

In low winds, the wing is inflated with a

forward launch, where the pilot runs forward with the wing behind so that the

air pressure generated by the forward movement inflates the wing.

It is often easier, because the pilot only

has to run forward, but the pilot cannot see his wing until it is above him,

where he has to check it in a very short time for correct inflation and

untangled lines before the launch.

Reverse launch

In higher winds, a reverse launch is used,

with the pilot facing the wing to bring it up into a flying position, then

turning around under the wing and running to complete the launch.

Land-based practice: Kiting

About that time, David Barish was

developing the "sail wing" (single-surface wing) for recovery of NASA

space capsules – "slope soaring was a way of testing out ... the Sail

Wing."[5] After tests on Hunter Mountain, New York, in September 1965, he

went on to promote slope soaring as a summer activity for ski resorts.[6][7]

Author Walter Neumark wrote Operating

Procedures for Ascending Parachutes, and in 1973 he and a group of enthusiasts

with a passion for tow-launching PCs and ram-air parachutes broke away from the

British Parachute Association to form the British Association of Parascending Clubs

(which later became the British Hang Gliding and Paragliding Association). In

1997, Neumark was awarded the Gold Medal of the Royal Aero Club of the UK.

Authors Patrick Gilligan (Canada) and Bertrand Dubuis (Switzerland) wrote the

first flight manual, The Paragliding Manual in 1985, coining the word

paragliding.
