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.

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).

Europe has seen the greatest growth in

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

Cross section of a paraglider

paraglider:

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]

滑翔伞在“大耳朵”机动

在不加速的情况下，正常飞行会拉动外部A线，使翼尖向内折叠，这将大大减小滑行角，而前进速度*会小幅下降。随着有效机翼面积的减小，机翼载荷增加，并且变得更加稳定。但是，迎角增加了，飞行器更接近失速速度，但是可以通过应用速度杆来改善，这也增加了下降速度。释放管路时，机翼会重新膨胀。如有必要，在制动器上短暂抽气有助于重新进入正常飞行。与其他技术相比，机翼大了，机翼仍然向前滑动，这使飞行员可以离开危险区域。例如，如果飞行员必须抵抗斜坡上的上升气流，这种方式甚至可以降落。

B线失速

在B线停转中，从前缘/前端起的第二组立管（B线）**于其他立管被下拉，其中特定的线用于启动停转。这在翼上产生翼展方向的折痕，从而使气流与翼的上表面分离。它显着降低了顶篷产生的升力，从而导致更高的下降率。这可能是费力的动作，因为必须将这些B线保持在该位置，并且机翼的张力会在这些线上施加向上的力。必须小心处理这些线的释放，以免引起机翼向前飞快射击，然后飞行员可能掉入其中。现在这已经不那么流行了，因为它在机翼的内部结构上引起了高负荷。

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.

在亚洲，日本、韩国、中国的中国台湾省等经济发达国家和地区的滑翔伞运动十分普及，爱好者达十多万人。20世纪80年代末，滑翔伞运动传入中国大陆并迅速发展，

现注册的航空俱乐部有50多个，正式会员1400多人，经常从事滑翔伞飞行者达数千人，在中国东北、长三角、珠三角长期有民间高手飞行，随着滑翔伞运动的逐渐普及，包括央视在内的很多电视媒体都对这一运动进行过专题报道。

滑翔伞通常主要由翼型伞衣、伞绳、背带系统和操纵系统四大部分组成。为便于滑翔伞的保管、携带与运输，每具滑翔伞还配有一只背式包装袋。

翼型伞衣，也称伞翼，是滑翔伞产生升力和承受载荷的主要部件。伞衣的形状、面积以及与气流相对运动的速度，对升力的产生有很大的影响。

翼型伞衣由上翼面、下翼面和沿翼展方向有规律分布的数十个成形翼肋构成。上下翼面与翼肋缝合，形成特定的伞翼形状。伞衣前缘按照翼肋的横向排列，构成一定尺寸的进气口。由于伞衣后缘是完全封闭的，所以上下翼面与各翼肋之间便形成了一个个用于储存空气的气室。 自动滑翔伞哪家快
