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.

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.

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)是最终的常见选择。它会降低机翼的升力性能。通过交替施加和释放制动器,下降速度大约每秒一次。该系统取决于飞行员对机翼的熟悉程度。机翼不得停转。应在飞行中,安全高度,良好条件下,并由观察员提供反馈的情况下,轻柔地进行安装。通常,制造商会根据批准重量范围内飞行员的平均身体比例来设定安全制动行程范围。应该以小幅增加对该设置进行更改,并在带有说明性标记的情况下显示这些变化,并进行试飞以确认所需的效果。缩短制动管路会产生使机翼变慢的问题。过度加长制动器会使机翼难以达到安全的着陆速度。
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).

与所有飞机一样,发射和降落都是在风中完成的。机翼通过奔跑或被拉动或存在的风被置于气流中。机翼在飞行员上方向上移动到可以运载乘客的位置。然后将飞行员从地面抬起,经过一段安全时期后,可以坐在他的安全带中。与跳伞运动员不同,滑翔伞与悬挂式滑翔伞一样,在此过程中不会随时“跳”起来。在高地上使用了两种发射技术[20],在平地地区使用了一种辅助发射技术:
向前发射
在低风中,机翼通过向前发射而膨胀,飞行员在前进时将机翼向后移动,以便向前运动产生的气压使机翼膨胀。
这通常更容易,因为飞行员只需要向前跑,但是飞行员直到机翼上方都看不到他的机翼为止,在那里他必须在很短的时间内检查一下机翼,以确保发射前有正确的充气和不纠缠的线。 奉贤区专用滑翔伞价格如何计算

Forward launch
In low winds, the wing is inflated with a
forward launch, where the pilot runs forward with the wing behind so that the
air pressure generated by the forward movement inflates the wing.
It is often easier, because the pilot only
has to run forward, but the pilot cannot see his wing until it is above him,
where he has to check it in a very short time for correct inflation and
untangled lines before the launch.
Reverse launch

In higher winds, a reverse launch is used,
with the pilot facing the wing to bring it up into a flying position, then
turning around under the wing and running to complete the launch.
