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.

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).

Paragliding is the recreational and competitive adventure sport of flying paragliders: lightweight, free-flying,

foot-launched glider aircraft with no rigid primary structure.[1] The pilot sits in a harness suspended below a fabric wing. Wing shape is maintained by the suspension lines, the pressure of air entering vents in the front of the wing, and the aerodynamic forces of the air flowing over the outside.

 Despite not using an engine, paragliderflights can last many hours and cover many hundreds of kilometres, though flights of one to two hours and covering some tens of kilometres are more the norm. By skillful exploitation of sources of lift, the pilot may gain height,

often climbing to altitudes of a few thousand metres.

Launching

As with all aircraft, launching and landing

are done into wind. The wing is placed into an airstream, either by running or

being pulled, or an existing wind. The wing moves up over the pilot into a

position in which it can carry the passenger. The pilot is then lifted from the

ground and, after a safety period, can sit down into his harness. Unlike

skydivers, paragliders, like hang gliders, do not "jump" at any time

during this process. There are two launching techniques used on higher

ground[20] and one assisted launch technique used in flatland areas:

滑翔傘在“大耳朵”機動

在不加速的情況下，正常飛行會拉動外部A線，使翼尖向內(nèi)折疊，這將大大減小滑行角，而前進速度*會小幅下降。隨著有效機翼面積的減小，機翼載荷增加，并且變得更加穩(wěn)定。但是，迎角增加了，飛行器更接近失速速度，但是可以通過應用速度桿來改善，這也增加了下降速度。釋放管路時，機翼會重新膨脹。如有必要，在制動器上短暫抽氣有助于重新進入正常飛行。與其他技術相比，機翼大了，機翼仍然向前滑動，這使飛行員可以離開危險區(qū)域。例如，如果飛行員必須抵抗斜坡上的上升氣流，這種方式甚至可以降落。

B線失速

在B線停轉中，從前緣/前端起的第二組立管（B線）**于其他立管被下拉，其中特定的線用于啟動停轉。這在翼上產(chǎn)生翼展方向的折痕，從而使氣流與翼的上表面分離。它顯著降低了頂篷產(chǎn)生的升力，從而導致更高的下降率。這可能是費力的動作，因為必須將這些B線保持在該位置，并且機翼的張力會在這些線上施加向上的力。必須小心處理這些線的釋放，以免引起機翼向前飛快射擊，然后飛行員可能掉入其中。現(xiàn)在這已經(jīng)不那么流行了，因為它在機翼的內(nèi)部結構上引起了高負荷。

在亞洲，日本、韓國、中國的中國臺灣省等經(jīng)濟發(fā)達國家和地區(qū)的滑翔傘運動十分普及，愛好者達十多萬人。20世紀80年代末，滑翔傘運動傳入中國大陸并迅速發(fā)展，

現(xiàn)注冊的航空俱樂部有50多個，正式會員1400多人，經(jīng)常從事滑翔傘飛行者達數(shù)千人，在中國東北、長三角、珠三角長期有民間高手飛行，隨著滑翔傘運動的逐漸普及，包括央視在內(nèi)的很多電視媒體都對這一運動進行過專題報道。

滑翔傘通常主要由翼型傘衣、傘繩、背帶系統(tǒng)和操縱系統(tǒng)四大部分組成。為便于滑翔傘的保管、攜帶與運輸，每具滑翔傘還配有一只背式包裝袋。

翼型傘衣，也稱傘翼，是滑翔傘產(chǎn)生升力和承受載荷的主要部件。傘衣的形狀、面積以及與氣流相對運動的速度，對升力的產(chǎn)生有很大的影響。

翼型傘衣由上翼面、下翼面和沿翼展方向有規(guī)律分布的數(shù)十個成形翼肋構成。上下翼面與翼肋縫合，形成特定的傘翼形狀。傘衣前緣按照翼肋的橫向排列，構成一定尺寸的進氣口。由于傘衣后緣是完全封閉的，所以上下翼面與各翼肋之間便形成了一個個用于儲存空氣的氣室。 閔行區(qū)通用滑翔傘詢問報價
