These developments were combined in June

1978 by three friends, Jean-Claude Bétemps, André Bohn and Gérard Bosson, from

Mieussy, Haute-Savoie, France. After inspiration from an article on slope

soaring in the Parachute Manual magazine by parachutist and publisher Dan

Poynter,[7] they calculated that on a suitable slope, a "square"

ram-air parachute could be inflated by running down the slope; Bétemps launched

from Pointe du Pertuiset, Mieussy, and flew 100 m. Bohn followed him and glided

down to the football pitch in the valley 1000 metres below.[8]

"Parapente" (pente being French for "slope") was born.

From the 1980s, equipment has continued to

improve, and the number of paragliding pilots and established sites has

continued to increase. The first (unofficial) Paragliding World Championship

was held in Verbier, Switzerland, in 1987,[9] though the first officially

sanctioned FAI World Paragliding Championship was held in Kössen, Austria, in

1989.[10]

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**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。

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]

飞行中的机翼放气（崩溃）

由于机翼（机翼）的形状是由进入机翼并使之膨胀的运动空气形成的，因此在湍流的空气中，机翼的一部分或全部会收缩（塌陷）。被称为“主动飞行”的飞行员技术将**降低通气或坍塌的频率和严重性。这种通缩通常无需飞行员干预即可恢复。如果发生严重的放气，正确的飞行员输入将加快从放气中恢复的速度，但是错误的飞行员输入会减慢滑翔机返回正常飞行的速度，因此飞行员必须进行正确的训练和练习以应对放气。

在极少数情况下，无法从通缩中恢复（或从诸如旋转等其他威胁性状况中）恢复过来的情况下，大多数飞行员会携带备用（救援，紧急情况）降落伞。但是，大多数飞行员从来没有理由“扔”他们的储备。如果机翼在低空发生放气，即在起飞后不久或着陆前不久，机翼（滑翔伞）可能无法迅速恢复其正确的结构以防止发生，飞行员通常没有足够的剩余高度来部署后备力量降落伞[**小降落高度大约为60 m（200 ft），但通常在稳定期使用120-180 m（390-590 ft）的高度进行典型部署]。备用降落伞的不同包装方式会影响其部署时间。

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.
