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(jī)翼或機(jī)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(guò)使大多數(shù)艙室*在前緣處敞開(kāi)，進(jìn)入的空氣使機(jī)翼保持充氣狀態(tài)，從而保持其形狀。充氣時(shí)，機(jī)翼的橫截面具有典型的淚滴翼型形狀?，F(xiàn)代滑翔傘的機(jī)翼是由高性能的無(wú)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(kāi)始中，尤其是性能更高的機(jī)翼中，前緣的某些艙室被封閉以形成更干凈的空氣動(dòng)力學(xué)輪廓。內(nèi)部肋骨上的孔允許空氣從開(kāi)孔到這些閉孔的自由流動(dòng)，以使它們膨脹，并向也閉合的翼尖膨脹。
飛行員通過(guò)懸吊線網(wǎng)絡(luò)支撐在機(jī)翼下方。這些從兩根短的（40厘米）長(zhǎng)的堅(jiān)固織帶制成的立管開(kāi)始。每組由一個(gè)登山扣固定在吊帶上，飛行員的每一側(cè)上各有一個(gè)，每個(gè)組的立管通常*從機(jī)翼一側(cè)的一行上連接到繩索上。在該組的每個(gè)立管的末端，都有一個(gè)小三角洲的馬龍，上面掛有數(shù)行（2 – 5）條線，形成一個(gè)風(fēng)扇。這些線通常長(zhǎng)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(xì)的細(xì)線上。在某些情況下，對(duì)第四級(jí)聯(lián)重復(fù)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.

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]
