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.

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.

Radio

Radio communications are used in training,

to communicate with other pilots, and to report where and when they intend to

land. These radios normally operate on a range of frequencies in different

countries—some authorised,[18][19] some illegal but tolerated locally. Some

local authorities (e.g., flight clubs) offer periodic automated weather updates

on these frequencies. In rare cases, pilots use radios to talk to airport

control towers or air traffic controllers. Many pilots carry a cell phone so

they can call for pickup should they land away from their intended point of

destination.

GPS

GPS (global positioning system) is a

necessary accessory when flying competitions, where it has to be demonstrated

that way-points have been correctly passed. The recorded GPS track of a flight

can be used to analyze flying technique or can be shared with other pilots. GPS

is also used to determine drift due to the prevailing wind when flying at

altitude, providing position information to allow restricted airspace to be

avoided and identifying one's location for retrieval teams after landing out in

unfamiliar territory. 

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。

  对于普通喜爱户外运动的人来说，经过滑翔伞教练的正规培训，要独自飞上蓝天其实很easy.客观的说，滑翔伞飞行是一项休闲航空运动，而非极限运动，只要身体无残疾、无精神疾病、无癫痫、无心脏病、等疾病的大众都可以参加.

      在欧洲的四亿人中，注册的滑翔伞飞行员已经达到两百多万人。而在中国13亿人中，学习滑翔伞飞行的人少之又少，持有中航协颁发的滑翔伞飞行执照的飞行员，截止2019年5月才刚好一万人。中国与欧洲甚至韩国日本的滑翔伞运动水平差距如此之大，是因为这项运动传入中国大陆较晚，并且中国人的运动观念保守，有点谈“空”色变，只要是与飞行有关的运动，普通人都敬而远之不敢尝试。其实，滑翔伞运动在欧洲还被戏虐的称之为“老头乐”，七、八十岁仍然在飞滑翔伞的人大有人在，飞行对于他们，是一生不变的爱好。 浦东新区通用滑翔伞哪家好

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).
