Paragliders are unique among human-carrying

aircraft in being easily portable. The complete equipment packs into a rucksack

and can be carried easily on the pilot's back, in a car, or on public

transport.[14] In comparison with other air sports, this substantially

simplifies travel to a suitable takeoff spot, the selection of a landing place

and return travel.

Tandem paragliders, designed to carry the

pilot and one passenger, are larger but otherwise similar. They usually fly

faster with higher trim speeds, are more resistant to collapse, and have a

slightly higher sink rate compared to solo paragliders.

In 1952 Canadian Domina Jalbert patented a

governable gliding parachute with multi-cells and controls for lateral

glide.[2]

In 1954, Walter Neumark predicted (in an

article in Flight magazine) a time when a glider pilot would be "able to

launch himself by running over the edge of a cliff or down a slope ... whether

on a rock-climbing holiday in Skye or ski-ing in the Alps."[3]

In 1961, the French engineer Pierre

Lemongine produced improved parachute designs that led to the Para-Commander.

The PC had cutouts at the rear and sides that enabled it to be towed into the

air and steered, leading to parasailing/parascending.

Domina Jalbert invented the Parafoil, which

had sectioned cells in an aerofoil shape; an open leading edge and a closed

trailing edge, inflated by passage through the air – the ram-air design. He

filed US Patent 3131894 on January 10, 1963.[4]

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。

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.

Europe has seen the greatest growth in

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

Wing

Cross section of a paraglider

Transverse cross section showing parts of a

paraglider:

1) upper surface

2) lower surface

3) rib

4) diagonal rib

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]

热飞行

托里·派恩斯滑翔伞在空中滑翔伞

当太阳温暖地面时，它将使某些功能比其他功能（例如岩石表面或大型建筑物）加热得更多，而这些功能会引发通过空气上升的热量。有时，这些可能只是空气的简单上升；通常，它们在风中向侧面吹，会从源头脱落，随后形成新的热量。

一旦飞行员找到了热量，他便开始绕圈飞行，试图将圆圈定位在热量**强的部分（“**”）上，其中空气的上升**快。大多数飞行员使用可变高度计（“ vario”），通过嘟嘟声和/或视觉显示来指示爬升率，以帮助将热量插入磁芯中。

通常情况下，周围的热源周围有很强的水槽，当飞行员试图进入强热源时，也存在强烈的湍流，导致机翼塌陷。良好的热力飞行是一项需要花费时间学习的技能，但是好的飞行员通常可以将热力一直贯穿到整个云层。

越野飞行

一旦掌握了使用热量来获得高度的技巧，飞行员就可以从一个热量滑到另一个热量来穿越国家。在热量中获得高度后，飞行员会下滑到下一个可用热量。

潜在的热量可以通过通常会产生热量的陆地特征或积云来识别，这些积云标志着上升的一列温暖，潮湿的空气在到达**并凝结成云时的顶部。

越野飞行员还需要熟悉航空法律，飞行法规，指示空域受限的航空地图等。
