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。

Europe has seen the greatest growth in
paragliding, with France alone registering in 2011 over 25,000 active pilots.

The paraglider wing or canopy is usually
what is known in engineering as a "ram-air airfoil". Such wings
comprise two layers of fabric that are connected to internal supporting
material in such a way as to form a row of cells. By leaving most of the cells
open only at the leading edge, incoming air keeps the wing inflated, thus
maintaining its shape. When inflated, the wing's cross-section has the typical
teardrop aerofoil shape. Modern paraglider wings are made of high-performance
non-porous materials such as ripstop polyester[12] or nylon fabric.[note 1]
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.
