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.

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.  宝山区滑翔伞价格合理

Land-based practice: Kiting

About that time, David Barish was

developing the "sail wing" (single-surface wing) for recovery of NASA

space capsules – "slope soaring was a way of testing out ... the Sail

Wing."[5] After tests on Hunter Mountain, New York, in September 1965, he

went on to promote slope soaring as a summer activity for ski resorts.[6][7]

Author Walter Neumark wrote Operating

Procedures for Ascending Parachutes, and in 1973 he and a group of enthusiasts

with a passion for tow-launching PCs and ram-air parachutes broke away from the

British Parachute Association to form the British Association of Parascending Clubs

(which later became the British Hang Gliding and Paragliding Association). In

1997, Neumark was awarded the Gold Medal of the Royal Aero Club of the UK.

Authors Patrick Gilligan (Canada) and Bertrand Dubuis (Switzerland) wrote the

first flight manual, The Paragliding Manual in 1985, coining the word

paragliding.

Reverse launches have a number of

advantages over a forward launch. It is more straightforward to inspect the

wing and check if the lines are free as it leaves the ground. In the presence

of wind, the pilot can be tugged toward the wing, and facing the wing makes it

easier to resist this force and safer in case the pilot slips (as opposed to

being dragged backwards). However, the movement pattern is more complex than

forward launch, and the pilot has to hold the brakes in a correct way and turn

to the correct side so he does not tangle the lines. These launches are

normally attempted with a reasonable wind speed, making the ground speed

required to pressurise the wing much lower.

The launch is initiated by the hands

raising the leading edge with the As. As it rises the wing is controlled more

by centring the feet than by use of the brakes or Cs. With mid level wings (EN

C and D) the wing may try to "overshoot" the pilot as it nears the

top. This is checked with Cs or brakes. The wing becomes increasingly sensitive

to the Cs and brakes as its internal air pressure rises. 

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。

安全

滑翔伞在巴西Araxá发射视频

像任何极限运动一样，滑翔伞是一种潜在的危险活动。例如，在美国，2010年，一名滑翔伞飞行员死亡。这相当于5,000名飞行员中的一名。在1994-2010年间，每10,000名活跃的滑翔伞飞行员中平均有7人受到致命伤害，尽管近年来情况已有明显改善。在法国（有超过25,000名注册机员），2011年每10,000名飞行员中有2人受伤（这一比率并非2007-2011年的非典型），尽管每1,000名飞行员中约有6人受到严重伤害（超过2名飞行员，日间住院）。

通过培训和风险管理可以**减少伤害的可能性。使用适当的设备，例如为飞行员的身材和技能水平设计的机翼[28]，以及头盔，备用降落伞[29]和缓冲式安全带[30]，也可以很大程度地降低风险。飞行员的安全受到对现场条件（如空气湍流（转子），强热，狂风和地面障碍物，如电力线）的了解的影响。胜任的教练对机翼控制和紧急演习进行足够的飞行员培训可以很大程度地减少。许多滑翔伞是飞行员错误和飞行条件差的结果。
