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).

In

flatter countryside, pilots can also be launched with a tow. Once at full

height (towing can launch pilots up to 3000 feet altitude), the pilot pulls a

release cord, and the towline falls away. This requires separate training, as

flying on a winch has quite different characteristics from free flying. There

are two major ways to tow: pay-in and pay-out towing. Pay-in towing involves a

stationary winch that winds in the towline and thereby pulls the pilot in the

air. The distance between winch and pilot at the start is around 500 metres or

more. Pay-out towing involves a moving object, like a car or a boat, that pays

out line slower than the speed of the object, thereby pulling the pilot up in

the air. In both cases, it is very important to have a gauge indicating line

tension to avoid pulling the pilot out of the air. Another form of towing is

"static line" towing. This involves a moving object, like a car or a

boat, attached to a paraglider or hang glider with a fixed-length line. 金山区口碑好滑翔伞好货源好价格

滑翔伞锦标赛开幕式在大明山举行，来自国内46名前列滑翔伞运动员参加此次锦标赛。航空运动管理中心办公室主任叶正福、自然保护区管理局滕达初副局长参加开幕式并致辞。

叶正福表示，滑翔伞运动，作为航空运动的重要项目之一，在我区起步虽晚，但发展势头强劲。近几年，滑翔运动如雨后春笋般在八桂大地上发展壮大，处处开花。通过大家的不懈努力，现在，广西的滑翔伞运动产业已初具规模。此次锦标赛的举办，为发展我区滑翔运动，提高我区滑翔运动竞技水平提供难得的机遇。

滕达初表示，本次赛事的举办，将极大促进大明山“山地户外运动”旅游品牌的打造，为塑造广西大明山——“中国·东盟户外运动中心”品牌助力。作为户外运动会重要活动之一的滑翔伞锦标赛，也将打造广西大明山航空旅游的新名片，进一步提高广西航空体育运动旅游、体育旅游的竞争力，进一步提高大明山**度，将大明山户外运动聚集地形象推至全国乃至世界。

This can be very dangerous, because now the

forces on the line have to be controlled by the moving object itself, which is

almost impossible to do, unless stretchy rope and a pressure/tension meter

(dynamometer) is used. Static line towing with stretchy rope and a load cell as

a tension meter has been used in Poland, Ukraine, Russia, and other Eastern

European countries for over twenty years (under the name Malinka) with about

the same safety record as other forms of towing.[21] One more form of towing is

hand towing. This is where 1−3 people pull a paraglider using a tow rope of up

to 500 feet. The stronger the wind, the fewer people are needed for a

successful hand tow.[22] Tows up to 300 feet have been accomplished, allowing

the pilot to get into a lift band of a nearby ridge or row of buildings and

ridge-soar in the lift the same way as with a regular foot launch.[23]

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。

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.
