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]

Paragliders are unique among human-carrying

aircraft in being easily portable. The complete equipment packs into a rucksack

and can be carried easily on the pilot's back, in a car, or on public

transport.[14] In comparison with other air sports, this substantially

simplifies travel to a suitable takeoff spot, the selection of a landing place

and return travel.

Tandem paragliders, designed to carry the

pilot and one passenger, are larger but otherwise similar. They usually fly

faster with higher trim speeds, are more resistant to collapse, and have a

slightly higher sink rate compared to solo paragliders.

着陆涉及更多的计划，因为可能有多个飞行员必须同时着陆。因此，已经建立了特定的流量模式。飞行员排在飞机场上方并降落在降落区一侧，该位置取决于风向，飞行员可能会因坐飞机而失去身高（如有必要）。从该位置开始，它们以矩形模式沿着飞行路径的腿到达着陆区：顺风腿进场。这允许在多个飞行员之间进行同步，并减少发生碰撞的风险，因为飞行员可以预测他周围的其他飞行员接下来将要做什么。

技术技巧

在进近下降过程中，在接触地面大约四米之前，可以施加一些瞬时制动，然后使用向前的摆动动量来获得速度，以更有效地展开并以**小的垂直速度接近地面。

在小风中，一些小跑很常见。在中等到中等的逆风中，着陆时可能没有前进速度，甚至在强风中甚至可能相对于地面后退。用风着陆会迫使飞行员向后退，这特别危险，因为它可能会翻滚并被拖拽。当机翼垂直于飞行员上方时，有可能降低风险放气。这涉及到每只手在槌/竖板交界处抓住前缘线（As），并通过深深的膝盖弯曲动作来施加飞行员的全部重量。在几乎每种情况下，机翼的前缘都会向前飞一点，然后“折”。然后，它可能会坍塌并下降到飞行员的上风处。在地面上，它将被飞行员的腿约束。

This can be very dangerous, because now the

forces on the line have to be controlled by the moving object itself, which is

almost impossible to do, unless stretchy rope and a pressure/tension meter

(dynamometer) is used. Static line towing with stretchy rope and a load cell as

a tension meter has been used in Poland, Ukraine, Russia, and other Eastern

European countries for over twenty years (under the name Malinka) with about

the same safety record as other forms of towing.[21] One more form of towing is

hand towing. This is where 1−3 people pull a paraglider using a tow rope of up

to 500 feet. The stronger the wind, the fewer people are needed for a

successful hand tow.[22] Tows up to 300 feet have been accomplished, allowing

the pilot to get into a lift band of a nearby ridge or row of buildings and

ridge-soar in the lift the same way as with a regular foot launch.[23]

These developments were combined in June

1978 by three friends, Jean-Claude Bétemps, André Bohn and Gérard Bosson, from

Mieussy, Haute-Savoie, France. After inspiration from an article on slope

soaring in the Parachute Manual magazine by parachutist and publisher Dan

Poynter,[7] they calculated that on a suitable slope, a "square"

ram-air parachute could be inflated by running down the slope; Bétemps launched

from Pointe du Pertuiset, Mieussy, and flew 100 m. Bohn followed him and glided

down to the football pitch in the valley 1000 metres below.[8]

"Parapente" (pente being French for "slope") was born.

From the 1980s, equipment has continued to

improve, and the number of paragliding pilots and established sites has

continued to increase. The first (unofficial) Paragliding World Championship

was held in Verbier, Switzerland, in 1987,[9] though the first officially

sanctioned FAI World Paragliding Championship was held in Kössen, Austria, in

1989.[10]

滑翔伞的机翼或机盖通常在工程上称为“冲压空气翼型”。这样的翼包括两层织物，它们以形成一排网孔的方式连接到内部支撑材料上。通过使大多数舱室*在前缘处敞开，进入的空气使机翼保持充气状态，从而保持其形状。充气时，机翼的横截面具有典型的泪滴翼型形状。现代滑翔伞的机翼是由高性能的无孔材料制成的，例如尼龙纤维。

在某些现代滑翔伞（从1990年开始中，尤其是性能更高的机翼中，前缘的某些舱室被封闭以形成更干净的空气动力学轮廓。内部肋骨上的孔允许空气从开孔到这些闭孔的自由流动，以使它们膨胀，并向也闭合的翼尖膨胀。

飞行员通过悬吊线网络支撑在机翼下方。这些从两根短的（40厘米）长的坚固织带制成的立管开始。每组由一个登山扣固定在吊带上，飞行员的每一侧上各有一个，每个组的立管通常*从机翼一侧的一行上连接到绳索上。在该组的每个立管的末端，都有一个小三角洲的马龙，上面挂有数行（2 – 5）条线，形成一个风扇。这些线通常长4 – 5米，末端连接到大约2 m的另外2 – 4条线上，这些线又连接到一组更细的细线上。在某些情况下，对第四级联重复此操作。
