A paraglider landing at Azheekkod beach,
India
As with all aircraft, launching and landing
are done into wind. The wing is placed into an airstream, either by running or
being pulled, or an existing wind. The wing moves up over the pilot into a
position in which it can carry the passenger. The pilot is then lifted from the
ground and, after a safety period, can sit down into his harness. Unlike
skydivers, paragliders, like hang gliders, do not "jump" at any time
during this process. There are two launching techniques used on higher
ground[20] and one assisted launch technique used in flatland areas:

The next step in the launch is to bring the
wing into the lift zone. There are two techniques for accomplishing this
depending on wind conditions. In light wind this is usually done after turning
to the front, steering with the feet towards the low wing tip, and applying
light brakes in a natural sense to keep the wing horizontal. In stronger wind
conditions it is often found to be easier to remain facing downwind while
moving slowly and steadily backwards into the wind.
Knees bent to load the wing, foot
adjustments to remain central and minimum use of Cs or Brakes to keep the wing
horizontal. Pirouette when the feet are close to lifting. This option has two
distinct advantages. a) The pilot can see the wing centre marker (an aid to
centring the feet) and, if necessary, b) the pilot can move briskly towards the
wing to assist with an emergency deflation.
With either method it is essential to check
"traffic" across the launch face before committing to flight.

滑翔伞是一批热爱跳伞、滑翔翼的飞行人员发明的一种飞行运动,目前在欧美和日本等国非常流行,在中国台湾也掀起了一股旋风。滑翔伞与传统的降落伞不同,它是一种飞行器。很久以前,人类为寻找一双翅膀作过无数次的思考和探索。在古老的中国大地上,留下了像“驾车遨游太空”、“嫦娥奔月”等许多关于人类尝试飞行的美好传说。当今,滑翔伞的诞生,为人类插上了飞翔的翅膀。人们自由地翱翔于天空,享受着“脱离”地球引力的宁静与美妙.滑翔伞起源于20世纪70年代初的欧洲,当时,一些登山者从山上乘降落伞滑翔而**验到了一种美好的感觉和乐趣,从而创立了一个新兴的航空体育项目。**初的滑翔伞是借鉴于飞机跳伞使用的翼型方伞,它主要以下降为主,下降速度快,安全性能好。通过二十多年的发展和演变。现在的滑翔伞**长飞行17小时,**远飞行距离超过300公里,它体现了一种人与自然的交流,备受崇尚自然者的喜爱。
每条线的顶部连接到缝在机翼结构中的小织物线圈上,这些织物线圈通常成行排列(即,左右)。**靠近前一行的行称为A线,下一行称为B线,依此类推。典型的机翼将具有A,B,C和D线,但是**近,有一种趋势是将行的行数减少到三行,甚至两行(并从实验上减少到一行),以减少阻力。
滑翔伞线通常由迪尼玛/光谱或凯夫拉尔/芳纶制成。尽管它们看起来很苗条,但这些材料非常坚固。例如,一条直径为0.66毫的线(大约**细)可以具有56千克的断裂强度。
滑翔伞的滑翔率范围从休闲机翼的9.3到现代竞赛模型的约11.3,在某些情况下高达13。为了进行比较,典型的跳伞降落伞将实现约3:1的滑行。悬挂式滑翔机的范围从休闲机翼的9.5到现代竞赛机型的约16.5。空转(滑行)的塞斯纳152轻型飞机将达到9:1。一些滑翔机可以实现高达72:1的滑行比。
滑翔伞的速度范围通常为每小时20-75公里(12-47英里/小时),从失速速度到比较大速度。初学者机翼将位于该范围的下部,高性能机翼将位于该范围的上部。
为了存放和携带,机翼通常被折叠成一个行李袋,然后可以与安全带一起存放在一个大背包中。对于可能不希望增加背包重量或烦恼的飞行员,一些现代安全带具有将安全带内翻的功能,从而使其成为背包。
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.

滑翔伞完整的设备打包成背包,可以轻松地放在飞行员的后背,汽车或公共交通工具上。[14]与其他航空运动相比,这**简化了到达合适起飞点的行程,着陆地点的选择和返程行程。
双人滑翔伞设计用来载飞行员和一名乘客,虽然较大,但在其他方面相似。与单独的滑翔伞相比,它们通常以更高的修剪速度飞行得更快,更不易塌陷,并且下沉率略高。

飞行员可以轻松舒适地扣入安全带,该安全带可在站立和坐姿中提供支撑。大多数安全带在座椅下方和后方都有泡沫或安全气囊保护装置,以减少对失败的发射或着陆造成的影响。现代安全带的设计使其在坐姿或躺姿时都像躺椅一样舒适。许多背带甚至具有可调节的“腰部支撑”。备用降落伞通常也连接至滑翔伞背带。
线束也根据飞行员的需求而有所不同,因此设计范围很广,主要是:初学者的训练用安全带,双人旅客的Pax防护带(通常还兼用作训练用安全带),长距离越野飞行的XC线束, Pod线束,适用于基本至中级飞行员的全能线束,适用于专注于XC的中级至专业飞行员。杂技安全带是专为杂技飞行员设计的,儿童双人安全带现在也提供特殊的儿童防盗锁。

尽可能避免降落对机翼过大的风。在接近预定着陆点的过程中,这种潜在问题通常很明显,并且可能有机会扩大飞行范围,以找到更庇护的着陆区域。在每次着陆时,都希望机翼保持可飞行状态,并具有少量前向动量。这使放气更加可控。尽管中线(Bs)是垂直的,但是机翼快速顺风移动的机会要少得多。常见的放气提示来自后提升板管线(Cs或Ds)上的剧烈拉力。迅速旋转以迎面迎风,在后立管上保持压力,并在机翼掉落时朝机翼轻快迈进。通过实践,有可能实现精确的安全“无故障停车”。 对于着陆进场期间的强风,“拍打”机翼(制动器对称脉动)是**终的常见选择。它会降低机翼的升力性能。通过交替施加和释放制动器,下降...
