滑翔傘的機翼或機蓋通常在工程上稱為“沖壓空氣翼型”。這樣的翼包括兩層織物，它們以形成一排網(wǎng)孔的方式連接到內(nèi)部支撐材料上。通過使大多數(shù)艙室*在前緣處敞開，進入的空氣使機翼保持充氣狀態(tài)，從而保持其形狀。充氣時，機翼的橫截面具有典型的淚滴翼型形狀。現(xiàn)代滑翔傘的機翼是由高性能的無孔材料制成的，例如尼龍纖維。

在某些現(xiàn)代滑翔傘（從1990年開始中，尤其是性能更高的機翼中，前緣的某些艙室被封閉以形成更干凈的空氣動力學輪廓。內(nèi)部肋骨上的孔允許空氣從開孔到這些閉孔的自由流動，以使它們膨脹，并向也閉合的翼尖膨脹。

飛行員通過懸吊線網(wǎng)絡支撐在機翼下方。這些從兩根短的（40厘米）長的堅固織帶制成的立管開始。每組由一個登山扣固定在吊帶上，飛行員的每一側(cè)上各有一個，每個組的立管通常*從機翼一側(cè)的一行上連接到繩索上。在該組的每個立管的末端，都有一個小三角洲的馬龍，上面掛有數(shù)行（2 – 5）條線，形成一個風扇。這些線通常長4 – 5米，末端連接到大約2 m的另外2 – 4條線上，這些線又連接到一組更細的細線上。在某些情況下，對第四級聯(lián)重復此操作。

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]

滑翔傘拖曳發(fā)射，波蘭米羅斯瓦維采

滑翔傘降落在印度Azheekkod海灘

與所有飛機一樣，發(fā)射和降落都是在風中完成的。機翼通過奔跑或被拉動或存在的風被置于氣流中。機翼在飛行員上方向上移動到可以運載乘客的位置。然后將飛行員從地面抬起，經(jīng)過一段安全時期后，可以坐在他的安全帶中。與跳傘運動員不同，滑翔傘與懸掛式滑翔傘一樣，在此過程中不會隨時“跳”起來。在高地上使用了兩種發(fā)射技術[20]，在平地地區(qū)使用了一種輔助發(fā)射技術：

向前發(fā)射

在低風中，機翼通過向前發(fā)射而膨脹，飛行員在前進時將機翼向后移動，以便向前運動產(chǎn)生的氣壓使機翼膨脹。

這通常更容易，因為飛行員只需要向前跑，但是飛行員直到機翼上方都看不到他的機翼為止，在那里他必須在很短的時間內(nèi)檢查一下機翼，以確保發(fā)射前有正確的充氣和不糾纏的線。

Forward launch

In low winds, the wing is inflated with a

forward launch, where the pilot runs forward with the wing behind so that the

air pressure generated by the forward movement inflates the wing.

It is often easier, because the pilot only

has to run forward, but the pilot cannot see his wing until it is above him,

where he has to check it in a very short time for correct inflation and

untangled lines before the launch.

Reverse launch

Paraglider reverse launch, Mam Tor, England

In higher winds, a reverse launch is used,

with the pilot facing the wing to bring it up into a flying position, then

turning around under the wing and running to complete the launch.

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.

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.
