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。 崇明区口碑好滑翔伞便宜

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.

SIV是模拟d'Incident en Vol（飞行中的事件模拟）的缩写，是提供有关如何应对不稳定和潜在危险情况（例如倒塌，满是失速和开裂）的课程。这些课程通常由经过特殊培训的讲师在大片水域上讲授，通常通过无线电指导学生。将指导学生如何诱发危险情况，从而学习一旦被诱发就如何避免和补救。向希望获得更高性能和更不稳定机翼的飞行员推荐该课程，这对于大多数飞行员而言都是自然而然的进步。在某些国家，SIV课程是初步飞行员培训的基本要求。万一出现无法挽回的机动导致水着陆的情况，通常会派出一艘救援船来收集飞行员。其他增加的安全功能可能包括浮力辅助装置或辅助备用降落伞。这些课程对于新手级别的飞行不是必不可少的。

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。

Europe has seen the greatest growth in

paragliding, with France alone registering in 2011 over 25,000 active pilots.

5) upper line cascade

6) middle line cascade

7) lower line cascade

8) risers

The paraglider wing or canopy is usually

what is known in engineering as a "ram-air airfoil". Such wings

comprise two layers of fabric that are connected to internal supporting

material in such a way as to form a row of cells. By leaving most of the cells

open only at the leading edge, incoming air keeps the wing inflated, thus

maintaining its shape. When inflated, the wing's cross-section has the typical

teardrop aerofoil shape. Modern paraglider wings are made of high-performance

non-porous materials such as ripstop polyester[12] or nylon fabric.[note 1]

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.
