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]

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]

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。

The next step in the launch is to bring the

wing into the lift zone. There are two techniques for accomplishing this

depending on wind conditions. In light wind this is usually done after turning

to the front, steering with the feet towards the low wing tip, and applying

light brakes in a natural sense to keep the wing horizontal. In stronger wind

conditions it is often found to be easier to remain facing downwind while

moving slowly and steadily backwards into the wind.

Knees bent to load the wing, foot

adjustments to remain central and minimum use of Cs or Brakes to keep the wing

horizontal. Pirouette when the feet are close to lifting. This option has two

distinct advantages. a) The pilot can see the wing centre marker (an aid to

centring the feet) and, if necessary, b) the pilot can move briskly towards the

wing to assist with an emergency deflation.

With either method it is essential to check

"traffic" across the launch face before committing to flight.

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]

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。
