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。

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.

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。
Launching

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 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).
