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]

滑翔伞是一批热爱跳伞、滑翔翼的飞行人员发明的一种飞行运动，目前在欧美和日本等国非常流行，在中国台湾也掀起了一股旋风。滑翔伞与传统的降落伞不同，它是一种飞行器。很久以前，人类为寻找一双翅膀作过无数次的思考和探索。在古老的中国大地上，留下了像“驾车遨游太空”、“嫦娥奔月”等许多关于人类尝试飞行的美好传说。当今，滑翔伞的诞生，为人类插上了飞翔的翅膀。人们自由地翱翔于天空，享受着“脱离”地球引力的宁静与美妙.滑翔伞起源于20世纪70年代初的欧洲，当时，一些登山者从山上乘降落伞滑翔而**验到了一种美好的感觉和乐趣，从而创立了一个新兴的航空体育项目。**初的滑翔伞是借鉴于飞机跳伞使用的翼型方伞，它主要以下降为主，下降速度快，安全性能好。通过二十多年的发展和演变。现在的滑翔伞**长飞行17小时，**远飞行距离超过300公里，它体现了一种人与自然的交流，备受崇尚自然者的喜爱。南京销售滑翔伞哪家强

Europe has seen the greatest growth in

paragliding, with France alone registering in 2011 over 25,000 active pilots.

Wing

Cross section of a paraglider

Transverse cross section showing parts of a

paraglider:

1) upper surface

2) lower surface

3) rib

4) diagonal rib

5) upper line cascade

6) middle line cascade

7) lower line cascade

8) risers

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]

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]

Launching

As with all aircraft, launching and landing

are done into wind. The wing is placed into an airstream, either by running or

being pulled, or an existing wind. The wing moves up over the pilot into a

position in which it can carry the passenger. The pilot is then lifted from the

ground and, after a safety period, can sit down into his harness. Unlike

skydivers, paragliders, like hang gliders, do not "jump" at any time

during this process. There are two launching techniques used on higher

ground[20] and one assisted launch technique used in flatland areas:

每条线的顶部连接到缝在机翼结构中的小织物线圈上，这些织物线圈通常成行排列（即，左右）。**靠近前一行的行称为A线，下一行称为B线，依此类推。典型的机翼将具有A，B，C和D线，但是**近，有一种趋势是将行的行数减少到三行，甚至两行（并从实验上减少到一行），以减少阻力。

滑翔伞线通常由迪尼玛/光谱或凯夫拉尔/芳纶制成。尽管它们看起来很苗条，但这些材料非常坚固。例如，一条直径为0.66毫的线（大约**细）可以具有56千克的断裂强度。

滑翔伞的滑翔率范围从休闲机翼的9.3到现代竞赛模型的约11.3，在某些情况下高达13。为了进行比较，典型的跳伞降落伞将实现约3：1的滑行。悬挂式滑翔机的范围从休闲机翼的9.5到现代竞赛机型的约16.5。空转（滑行）的塞斯纳152轻型飞机将达到9：1。一些滑翔机可以实现高达72：1的滑行比。

滑翔伞的速度范围通常为每小时20-75公里（12-47英里/小时），从失速速度到比较大速度。初学者机翼将位于该范围的下部，高性能机翼将位于该范围的上部。

为了存放和携带，机翼通常被折叠成一个行李袋，然后可以与安全带一起存放在一个大背包中。对于可能不希望增加背包重量或烦恼的飞行员，一些现代安全带具有将安全带内翻的功能，从而使其成为背包。
