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。

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.

滑翔伞是飞行滑翔伞的娱乐和竞争性冒险运动:轻巧,自由飞行,脚踩滑翔机,没有刚性的基本结构[1]。

飞行员坐在悬挂在机翼下方的安全带中。

悬挂线,进入机翼前部通风孔的空气压力以及流过外部的空气的空气动力保持了机翼的形状。


尽管不使用发动机,滑翔伞飞行仍可持续数小时,飞行数百公里,尽管更常见的是飞行一到两个小时,飞行数十公里。

通过熟练地利用升力源,飞行员可以增加身高,通常会爬升到几千米的高度。


1954年,沃尔特·纽马克(Walter

Neumark)预测(在《飞行》杂志上的一篇文章),滑翔机飞行员“能够通过在悬崖边缘或斜坡上奔跑来发动自己……无论是在美国的攀岩假期中,

斯凯岛或阿尔卑斯山滑雪。”


1961年,法国工程师Pierre Lemongine制作了改进的降落伞设计,从而设计了Para-Commander。 PC的后部和侧面均设有切口,可将其拖入空中并进行操纵,从而实现滑翔伞运动。

多米娜·贾伯特(Domina Jalbert)发明了Parafoil,它具有呈翼型形状的切片细胞。 敞开式前缘和封闭式后缘,通过空气而膨胀-冲压空气设计。 他于1963年1月10日提交了美国专利3131894。


Paragliding is the recreational and competitive adventure sport of flying paragliders: lightweight, free-flying,

foot-launched glider aircraft with no rigid primary structure.[1] The pilot sits in a harness suspended below a fabric wing. Wing shape is maintained by the suspension lines, the pressure of air entering vents in the front of the wing, and the aerodynamic forces of the air flowing over the outside.

 Despite not using an engine, paragliderflights can last many hours and cover many hundreds of kilometres, though flights of one to two hours and covering some tens of kilometres are more the norm. By skillful exploitation of sources of lift, the pilot may gain height,

often climbing to altitudes of a few thousand metres.




Radio

Radio communications are used in training,

to communicate with other pilots, and to report where and when they intend to

land. These radios normally operate on a range of frequencies in different

countries—some authorised,[18][19] some illegal but tolerated locally. Some

local authorities (e.g., flight clubs) offer periodic automated weather updates

on these frequencies. In rare cases, pilots use radios to talk to airport

control towers or air traffic controllers. Many pilots carry a cell phone so

they can call for pickup should they land away from their intended point of

destination.


GPS

GPS (global positioning system) is a

necessary accessory when flying competitions, where it has to be demonstrated

that way-points have been correctly passed. The recorded GPS track of a flight

can be used to analyze flying technique or can be shared with other pilots. GPS

is also used to determine drift due to the prevailing wind when flying at

altitude, providing position information to allow restricted airspace to be

avoided and identifying one's location for retrieval teams after landing out in

unfamiliar territory.  常州**滑翔伞省钱
