大约在那个时候,大卫·巴里什(David Barish)正在开发用于恢复NASA太空舱的“帆翼”(单面翼)-“高耸的斜坡是一种测试……帆翼的方法。” 在对Hunter进行测试之后1965年9月,他在纽约的山上继续推广滑雪胜地的夏季活动[6] [7]。
作者Walter Neumark撰写了《降落伞操作程序》,并于1973年与一群对拖曳PC和ram-air降落伞充满热情的爱好者脱离了英国降落伞协会,成立了英国降落伞俱乐部协会(此协会后来成为英国的滑翔伞和滑翔伞协会)。 1997年,纽马克(Neumark)被英国皇家航空俱乐部(Royal Aero Club)授予奖牌。作家Patrick Gilligan(加拿大)和Bertrand Dubuis(瑞士)于1985年撰写了首本飞行手册《滑翔伞手册》,创造了滑翔伞一词。
1978年6月,来自法国上萨瓦省Mieussy的三个朋友Jean-ClaudeBétemps,AndréBohn和GérardBosson将这些发展合并在一起。在跳伞者和发行人丹·波因特(Dan Poynter)在《降落伞手册》杂志上发表的一篇有关坡度飞涨的文章的灵感启发之后,[7]他们计算出,在合适的坡度上,可以通过顺着坡道向“方形”的冲压空气降落伞充气; Bétemps从Mieussy的Pointe du Pertuiset发射升空100 m。博恩跟随他,滑到1000米以下山谷的足球场。

滑翔伞锦标赛开幕式在大明山举行,来自国内46名前列滑翔伞运动员参加此次锦标赛。航空运动管理中心办公室主任叶正福、自然保护区管理局滕达初副局长参加开幕式并致辞。
叶正福表示,滑翔伞运动,作为航空运动的重要项目之一,在我区起步虽晚,但发展势头强劲。近几年,滑翔运动如雨后春笋般在八桂大地上发展壮大,处处开花。通过大家的不懈努力,现在,广西的滑翔伞运动产业已初具规模。此次锦标赛的举办,为发展我区滑翔运动,提高我区滑翔运动竞技水平提供难得的机遇。
滕达初表示,本次赛事的举办,将极大促进大明山“山地户外运动”旅游品牌的打造,为塑造广西大明山——“中国·东盟户外运动中心”品牌助力。作为户外运动会重要活动之一的滑翔伞锦标赛,也将打造广西大明山航空旅游的新名片,进一步提高广西航空体育运动旅游、体育旅游的竞争力,进一步提高大明山**度,将大明山户外运动聚集地形象推至全国乃至世界。

飞行中的机翼放气(崩溃)
由于机翼(机翼)的形状是由进入机翼并使之膨胀的运动空气形成的,因此在湍流的空气中,机翼的一部分或全部会收缩(塌陷)。被称为“主动飞行”的飞行员技术将**降低通气或坍塌的频率和严重性。这种通缩通常无需飞行员干预即可恢复。如果发生严重的放气,正确的飞行员输入将加快从放气中恢复的速度,但是错误的飞行员输入会减慢滑翔机返回正常飞行的速度,因此飞行员必须进行正确的训练和练习以应对放气。
在极少数情况下,无法从通缩中恢复(或从诸如旋转等其他威胁性状况中)恢复过来的情况下,大多数飞行员会携带备用(救援,紧急情况)降落伞。但是,大多数飞行员从来没有理由“扔”他们的储备。如果机翼在低空发生放气,即在起飞后不久或着陆前不久,机翼(滑翔伞)可能无法迅速恢复其正确的结构以防止发生,飞行员通常没有足够的剩余高度来部署后备力量降落伞[**小降落高度大约为60 m(200 ft),但通常在稳定期使用120-180 m(390-590 ft)的高度进行典型部署]。备用降落伞的不同包装方式会影响其部署时间。
These developments were combined in June
1978 by three friends, Jean-Claude B茅temps, Andr茅 Bohn and G茅rard 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; B茅temps 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枚ssen, Austria, in
1989.[10]
Forward launch
In low winds, the wing is inflated with a
forward launch, where the pilot runs forward with the wing behind so that the
air pressure generated by the forward movement inflates the wing.
It is often easier, because the pilot only
has to run forward, but the pilot cannot see his wing until it is above him,
where he has to check it in a very short time for correct inflation and
untangled lines before the launch.
Reverse launch

In higher winds, a reverse launch is used,
with the pilot facing the wing to bring it up into a flying position, then
turning around under the wing and running to complete the launch.

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

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]
