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 K?ssen, Austria, in
1989.[10]

現(xiàn)注冊(cè)的航空俱樂(lè)部有50多個(gè)，正式會(huì)員1400多人，經(jīng)常從事滑翔傘飛行者達(dá)數(shù)千人，在中國(guó)東北、長(zhǎng)三角、珠三角長(zhǎng)期有民間高手飛行，隨著滑翔傘運(yùn)動(dòng)的逐漸普及，包括央視在內(nèi)的很多電視媒體都對(duì)這一運(yùn)動(dòng)進(jìn)行過(guò)專(zhuān)題報(bào)道。
滑翔傘通常主要由翼型傘衣、傘繩、背帶系統(tǒng)和操縱系統(tǒng)四大部分組成。為便于滑翔傘的保管、攜帶與運(yùn)輸，每具滑翔傘還配有一只背式包裝袋。
翼型傘衣，也稱(chēng)傘翼，是滑翔傘產(chǎn)生升力和承受載荷的主要部件。傘衣的形狀、面積以及與氣流相對(duì)運(yùn)動(dòng)的速度，對(duì)升力的產(chǎn)生有很大的影響。
翼型傘衣由上翼面、下翼面和沿翼展方向有規(guī)律分布的數(shù)十個(gè)成形翼肋構(gòu)成。上下翼面與翼肋縫合，形成特定的傘翼形狀。傘衣前緣按照翼肋的橫向排列，構(gòu)成一定尺寸的進(jìn)氣口。由于傘衣后緣是完全封閉的，所以上下翼面與各翼肋之間便形成了一個(gè)個(gè)用于儲(chǔ)存空氣的氣室。 奉賢區(qū)官方滑翔傘哪家快

滑翔傘的機(jī)翼或機(jī)蓋通常在工程上稱(chēng)為“沖壓空氣翼型”。這樣的翼包括兩層織物，它們以形成一排網(wǎng)孔的方式連接到內(nèi)部支撐材料上。通過(guò)使大多數(shù)艙室*在前緣處敞開(kāi)，進(jìn)入的空氣使機(jī)翼保持充氣狀態(tài)，從而保持其形狀。充氣時(shí)，機(jī)翼的橫截面具有典型的淚滴翼型形狀?，F(xiàn)代滑翔傘的機(jī)翼是由高性能的無(wú)孔材料制成的，例如尼龍纖維。
在某些現(xiàn)代滑翔傘（從1990年開(kāi)始中，尤其是性能更高的機(jī)翼中，前緣的某些艙室被封閉以形成更干凈的空氣動(dòng)力學(xué)輪廓。內(nèi)部肋骨上的孔允許空氣從開(kāi)孔到這些閉孔的自由流動(dòng)，以使它們膨脹，并向也閉合的翼尖膨脹。

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.
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]

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]
