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.

著陸涉及更多的計劃,因為可能有多個飛行員必須同時著陸。因此,已經建立了特定的流量模式。飛行員排在飛機場上方并降落在降落區一側,該位置取決于風向,飛行員可能會因坐飛機而失去身高(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著陸區:順風腿進場。這允許在多個飛行員之間進行同步,并減少發生碰撞的風險,因為飛行員可以預測他周圍的其他飛行員接下來將要做什么。
技術技巧
在進近下降過程中,在接觸地面大約四米之前,可以施加一些瞬時制動,然后使用向前的擺動動量來獲得速度,以更有效地展開并以**小的垂直速度接近地面。
在小風中,一些小跑很常見。在中等到中等的逆風中,著陸時可能沒有前進速度,甚至在強風中甚至可能相對于地面后退。用風著陸會迫使飛行員向后退,這特別危險,因為它可能會翻滾并被拖拽。當機翼垂直于飛行員上方時,有可能降低風險放氣。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作來施加飛行員的全部重量。在幾乎每種情況下,機翼的前緣都會向前飛一點,然后“折”。然后,它可能會坍塌并下降到飛行員的上風處。在地面上,它將被飛行員的腿約束。

飛行中的機翼放氣(崩潰)
由于機翼(機翼)的形狀是由進入機翼并使之膨脹的運動空氣形成的,因此在湍流的空氣中,機翼的一部分或全部會收縮(塌陷)。被稱為“主動飛行”的飛行員技術將**降低通氣或坍塌的頻率和嚴重性。這種通縮通常無需飛行員干預即可恢復。如果發生嚴重的放氣,正確的飛行員輸入將加快從放氣中恢復的速度,但是錯誤的飛行員輸入會減慢滑翔機返回正常飛行的速度,因此飛行員必須進行正確的訓練和練習以應對放氣。
在極少數情況下,無法從通縮中恢復(或從諸如旋轉等其他威脅性狀況中)恢復過來的情況下,大多數飛行員會攜帶備用(救援,緊急情況)降落傘。但是,大多數飛行員從來沒有理由“扔”他們的儲備。如果機翼在低空發生放氣,即在起飛后不久或著陸前不久,機翼(滑翔傘)可能無法迅速恢復其正確的結構以防止發生,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),但通常在穩定期使用120-180 m(390-590 ft)的高度進行典型部署]。備用降落傘的不同包裝方式會影響其部署時間。
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]
