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(yīng)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(shù)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(zhuǎn)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(zhuǎn)。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(dǎo)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(jié)構(gòu)上引起了高負荷。

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 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.

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.
