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]

滑翔傘的機翼或機蓋通常在工程上稱為“沖壓空氣翼型”。這樣的翼包括兩層織物,它們以形成一排網孔的方式連接到內部支撐材料上。通過使大多數艙室*在前緣處敞開,進入的空氣使機翼保持充氣狀態,從而保持其形狀。充氣時,機翼的橫截面具有典型的淚滴翼型形狀。現代滑翔傘的機翼是由高性能的無孔材料制成的,例如尼龍纖維。

在某些現代滑翔傘(從1990年開始中,尤其是性能更高的機翼中,前緣的某些艙室被封閉以形成更干凈的空氣動力學輪廓。內部肋骨上的孔允許空氣從開孔到這些閉孔的自由流動,以使它們膨脹,并向也閉合的翼尖膨脹。


飛行員通過懸吊線網絡支撐在機翼下方。這些從兩根短的(40厘米)長的堅固織帶制成的立管開始。每組由一個登山扣固定在吊帶上,飛行員的每一側上各有一個,每個組的立管通常*從機翼一側的一行上連接到繩索上。在該組的每個立管的末端,都有一個小三角洲的馬龍,上面掛有數行(2 – 5)條線,形成一個風扇。這些線通常長4 – 5米,末端連接到大約2 m的另外2 – 4條線上,這些線又連接到一組更細的細線上。在某些情況下,對第四級聯重復此操作。

無動力滑翔傘是借助傘翼在空中相對空氣的運動產生的升力,由飛行員通過操縱繩控制速度、方向等,實現無動力滑翔傘自由翱翔的。它起源于法國,于上世紀八十年代傳入中國,截至目前,國內的持證滑翔傘飛行員剛剛過萬人,是極富魅力與想象力并且很厲害的潮人運動。

      請記住,滑翔傘不是降落傘,降落傘是“可展式氣動阻力器”,它能讓人或物體從空中以較小的勻速下降。而滑翔傘是人類目前創造出的簡易的飛行器,它能借助對流層中的熱氣流越飛越高,直到云底或者熱氣流消散的積云頂端。


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.



大約在那個時候,大衛·巴里什(David Barish)正在開發用于恢復NASA太空艙的“帆翼”(單面翼)-“高聳的斜坡是一種測試……帆翼的方法。” 在對Hunter進行測試之后1965年9月,他在紐約的山上繼續推廣滑雪勝地的夏季活動[6] [7]。


作者Walter Neumark撰寫了《降落傘操作程序》,并于1973年與一群對拖曳PC和ram-air降落傘充滿熱情的愛好者脫離了英國降落傘協會,成立了英國降落傘俱樂部協會(此協會后來成為英國的滑翔傘和滑翔傘協會)。 1997年,紐馬克(Neumark)被英國皇家航空俱樂部(Royal Aero Club)授予獎牌。作家Patrick Gilligan(加拿大)和Bertrand Dubuis(瑞士)于1985年撰寫了首本飛行手冊《滑翔傘手冊》,創造了滑翔傘一詞。


1978年6月,來自法國上薩瓦省Mieussy的三個朋友Jean-ClaudeBétemps,AndréBohn和GérardBosson將這些發展合并在一起。在跳傘者和發行人丹·波因特(Dan Poynter)在《降落傘手冊》雜志上發表的一篇有關坡度飛漲的文章的靈感啟發之后,[7]他們計算出,在合適的坡度上,可以通過順著坡道向“方形”的沖壓空氣降落傘充氣; Bétemps從Mieussy的Pointe du Pertuiset發射升空100 m。博恩跟隨他,滑到1000米以下山谷的足球場。

The top of each line is attached to small

fabric loops sewn into the structure of the wing, which are generally arranged

in rows running span-wise (i.e., side to side). The row of lines nearest the

front are known as the A lines, the next row back the B lines, and so on.[14] A

typical wing will have A, B, C and D lines, but recently, there has been a

tendency to reduce the rows of lines to three, or even two (and experimentally

to one), to reduce drag.


Paraglider lines are usually made from

Dyneema/Spectra or Kevlar/Aramid.[14] Although they look rather slender, these

materials are immensely strong. For example, a single 0.66 mm-diameter line

(about the thinnest used) can have a breaking strength of 56 kg.[15]


Paraglider wings typically have an area of

20–35 square metres (220–380 sq ft) with a span of 8–12 metres (26–39 ft) and

weigh 3–7 kilograms (6.6–15.4 lb). Combined weight of wing, harness, reserve,

instruments, helmet, etc. is around 12–22 kilograms (26–49 lb).
