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.

著陸涉及更多的計(jì)劃，因?yàn)榭赡苡卸鄠€(gè)飛行員必須同時(shí)著陸。因此，已經(jīng)建立了特定的流量模式。飛行員排在飛機(jī)場上方并降落在降落區(qū)一側(cè)，該位置取決于風(fēng)向，飛行員可能會(huì)因坐飛機(jī)而失去身高（如有必要）。從該位置開始，它們以矩形模式沿著飛行路徑的腿到達(dá)著陸區(qū)：順風(fēng)腿進(jìn)場。這允許在多個(gè)飛行員之間進(jìn)行同步，并減少發(fā)生碰撞的風(fēng)險(xiǎn)，因?yàn)轱w行員可以預(yù)測他周圍的其他飛行員接下來將要做什么。

技術(shù)技巧

在進(jìn)近下降過程中，在接觸地面大約四米之前，可以施加一些瞬時(shí)制動(dòng)，然后使用向前的擺動(dòng)動(dòng)量來獲得速度，以更有效地展開并以**小的垂直速度接近地面。

在小風(fēng)中，一些小跑很常見。在中等到中等的逆風(fēng)中，著陸時(shí)可能沒有前進(jìn)速度，甚至在強(qiáng)風(fēng)中甚至可能相對(duì)于地面后退。用風(fēng)著陸會(huì)迫使飛行員向后退，這特別危險(xiǎn)，因?yàn)樗赡軙?huì)翻滾并被拖拽。當(dāng)機(jī)翼垂直于飛行員上方時(shí)，有可能降低風(fēng)險(xiǎn)放氣。這涉及到每只手在槌/豎板交界處抓住前緣線（As），并通過深深的膝蓋彎曲動(dòng)作來施加飛行員的全部重量。在幾乎每種情況下，機(jī)翼的前緣都會(huì)向前飛一點(diǎn)，然后“折”。然后，它可能會(huì)坍塌并下降到飛行員的上風(fēng)處。在地面上，它將被飛行員的腿約束。

飛行中的機(jī)翼放氣（崩潰）

由于機(jī)翼（機(jī)翼）的形狀是由進(jìn)入機(jī)翼并使之膨脹的運(yùn)動(dòng)空氣形成的，因此在湍流的空氣中，機(jī)翼的一部分或全部會(huì)收縮（塌陷）。被稱為“主動(dòng)飛行”的飛行員技術(shù)將**降低通氣或坍塌的頻率和嚴(yán)重性。這種通縮通常無需飛行員干預(yù)即可恢復(fù)。如果發(fā)生嚴(yán)重的放氣，正確的飛行員輸入將加快從放氣中恢復(fù)的速度，但是錯(cuò)誤的飛行員輸入會(huì)減慢滑翔機(jī)返回正常飛行的速度，因此飛行員必須進(jìn)行正確的訓(xùn)練和練習(xí)以應(yīng)對(duì)放氣。

在極少數(shù)情況下，無法從通縮中恢復(fù)（或從諸如旋轉(zhuǎn)等其他威脅性狀況中）恢復(fù)過來的情況下，大多數(shù)飛行員會(huì)攜帶備用（救援，緊急情況）降落傘。但是，大多數(shù)飛行員從來沒有理由“扔”他們的儲(chǔ)備。如果機(jī)翼在低空發(fā)生放氣，即在起飛后不久或著陸前不久，機(jī)翼（滑翔傘）可能無法迅速恢復(fù)其正確的結(jié)構(gòu)以防止發(fā)生，飛行員通常沒有足夠的剩余高度來部署后備力量降落傘[**小降落高度大約為60 m（200 ft），但通常在穩(wěn)定期使用120-180 m（390-590 ft）的高度進(jìn)行典型部署]。備用降落傘的不同包裝方式會(huì)影響其部署時(shí)間。

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.

In 1952 Canadian Domina Jalbert patented a

governable gliding parachute with multi-cells and controls for lateral

glide.[2]

In 1954, Walter Neumark predicted (in an

article in Flight magazine) a time when a glider pilot would be "able to

launch himself by running over the edge of a cliff or down a slope ... whether

on a rock-climbing holiday in Skye or ski-ing in the Alps."[3]

In 1961, the French engineer Pierre

Lemongine produced improved parachute designs that led to the Para-Commander.

The PC had cutouts at the rear and sides that enabled it to be towed into the

air and steered, leading to parasailing/parascending.

Domina Jalbert invented the Parafoil, which

had sectioned cells in an aerofoil shape; an open leading edge and a closed

trailing edge, inflated by passage through the air – the ram-air design. He

filed US Patent 3131894 on January 10, 1963.[4]
