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 K?ssen, Austria, in

1989.[10]

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，它們以形成一排網孔的方式連接到內部支撐材料上。通過使大多數艙室*在前緣處敞開，進入的空氣使機翼保持充氣狀態，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，飛行員的每一側上各有一個，每個組的立管通常*從機翼一側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，對第四級聯重復此操作。

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.

Radio

Radio communications are used in training,

to communicate with other pilots, and to report where and when they intend to

land. These radios normally operate on a range of frequencies in different

countries—some authorised,[18][19] some illegal but tolerated locally. Some

local authorities (e.g., flight clubs) offer periodic automated weather updates

on these frequencies. In rare cases, pilots use radios to talk to airport

control towers or air traffic controllers. Many pilots carry a cell phone so

they can call for pickup should they land away from their intended point of

destination.

GPS

GPS (global positioning system) is a

necessary accessory when flying competitions, where it has to be demonstrated

that way-points have been correctly passed. The recorded GPS track of a flight

can be used to analyze flying technique or can be shared with other pilots. GPS

is also used to determine drift due to the prevailing wind when flying at

altitude, providing position information to allow restricted airspace to be

avoided and identifying one's location for retrieval teams after landing out in

unfamiliar territory. 

盡可能避免降落對機翼過大的風。在接近預定著陸點的過程中，這種潛在問題通常很明顯，并且可能有機會擴大飛行范圍，以找到更庇護的著陸區域。在每次著陸時，都希望機翼保持可飛行狀態，并具有少量前向動量。這使放氣更加可控。盡管中線（Bs）是垂直的，但是機翼快速順風移動的機會要少得多。常見的放氣提示來自后提升板管線（Cs或Ds）上的劇烈拉力。迅速旋轉以迎面迎風，在后立管上保持壓力，并在機翼掉落時朝機翼輕快邁進。通過實踐，有可能實現精確的安全“無故障停車”。

對于著陸進場期間的強風，“拍打”機翼（制動器對稱脈動）是**終的常見選擇。它會降低機翼的升力性能。通過交替施加和釋放制動器，下降速度大約每秒一次。該系統取決于飛行員對機翼的熟悉程度。機翼不得停轉。應在飛行中，安全高度，良好條件下，并由觀察員提供反饋的情況下，輕柔地進行安裝。通常，制造商會根據批準重量范圍內飛行員的平均身體比例來設定安全制動行程范圍。應該以小幅增加對該設置進行更改，并在帶有說明性標記的情況下顯示這些變化，并進行試飛以確認所需的效果。縮短制動管路會產生使機翼變慢的問題。過度加長制動器會使機翼難以達到安全的著陸速度。

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]
