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).

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.  嘉定区职业滑翔伞多少钱

滑翔伞的机翼或机盖通常在工程上称为“冲压空气翼型”。这样的翼包括两层织物，它们以形成一排网孔的方式连接到内部支撑材料上。通过使大多数舱室*在前缘处敞开，进入的空气使机翼保持充气状态，从而保持其形状。充气时，机翼的横截面具有典型的泪滴翼型形状。现代滑翔伞的机翼是由高性能的无孔材料制成的，例如尼龙纤维。

在某些现代滑翔伞（从1990年开始中，尤其是性能更高的机翼中，前缘的某些舱室被封闭以形成更干净的空气动力学轮廓。内部肋骨上的孔允许空气从开孔到这些闭孔的自由流动，以使它们膨胀，并向也闭合的翼尖膨胀。

飞行员通过悬吊线网络支撑在机翼下方。这些从两根短的（40厘米）长的坚固织带制成的立管开始。每组由一个登山扣固定在吊带上，飞行员的每一侧上各有一个，每个组的立管通常*从机翼一侧的一行上连接到绳索上。在该组的每个立管的末端，都有一个小三角洲的马龙，上面挂有数行（2 – 5）条线，形成一个风扇。这些线通常长4 – 5米，末端连接到大约2 m的另外2 – 4条线上，这些线又连接到一组更细的细线上。在某些情况下，对第四级联重复此操作。

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。

无动力滑翔伞是借助伞翼在空中相对空气的运动产生的升力，由飞行员通过操纵绳控制速度、方向等，实现无动力滑翔伞自由翱翔的。它起源于法国，于上世纪八十年代传入中国，截至目前，国内的持证滑翔伞飞行员刚刚过万人，是极富魅力与想象力并且很厉害的潮人运动。

      请记住，滑翔伞不是降落伞，降落伞是“可展式气动阻力器”，它能让人或物体从空中以较小的匀速下降。而滑翔伞是人类目前创造出的简易的飞行器，它能借助对流层中的热气流越飞越高，直到云底或者热气流消散的积云顶端。 徐汇区通用滑翔伞价格行情

The glide ratio of paragliders ranges from

9.3 for recreational wings to about 11.3 for modern competition models,[16]

reaching in some cases up to 13.[17] For comparison, a typical skydiving

parachute will achieve about 3:1 glide. A hang glider ranges from 9.5 for

recreational wings to about 16.5 for modern competition models. An idling

(gliding) Cessna 152 light aircraft will achieve 9:1. Some sailplanes can

achieve a glide ratio of up to 72:1.

The speed range of paragliders is typically

20–75 kilometres per hour (12–47 mph), from stall speed to maximum speed.

Beginner wings will be in the lower part of this range, high-performance wings

in the upper part of the range.[note 2]

For storage and carrying, the wing is

usually folded into a stuffsack (bag), which can then be stowed in a large

backpack along with the harness. For pilots who may not want the added weight

or fuss of a backpack, some modern harnesses include the ability to turn the

harness inside out such that it becomes a backpack.
