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.

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.
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。
This can be very dangerous, because now the
forces on the line have to be controlled by the moving object itself, which is
almost impossible to do, unless stretchy rope and a pressure/tension meter
(dynamometer) is used. Static line towing with stretchy rope and a load cell as
a tension meter has been used in Poland, Ukraine, Russia, and other Eastern
European countries for over twenty years (under the name Malinka) with about
the same safety record as other forms of towing.[21] One more form of towing is
hand towing. This is where 1−3 people pull a paraglider using a tow rope of up
to 500 feet. The stronger the wind, the fewer people are needed for a
successful hand tow.[22] Tows up to 300 feet have been accomplished, allowing
the pilot to get into a lift band of a nearby ridge or row of buildings and
ridge-soar in the lift the same way as with a regular foot launch.[23]

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。
