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.

大約在那個時候，大衛·巴里什（David Barish）正在開發用于恢復NASA太空艙的“帆翼”（單面翼）-“高聳的斜坡是一種測試……帆翼的方法。” 在對Hunter進行測試之后1965年9月，他在紐約的山上繼續推廣滑雪勝地的夏季活動[6] [7]。

作者Walter Neumark撰寫了《降落傘操作程序》，并于1973年與一群對拖曳PC和ram-air降落傘充滿熱情的愛好者脫離了英國降落傘協會，成立了英國降落傘俱樂部協會（此協會后來成為英國的滑翔傘和滑翔傘協會）。 1997年，紐馬克（Neumark）被英國皇家航空俱樂部（Royal Aero Club）授予獎牌。作家Patrick Gilligan（加拿大）和Bertrand Dubuis（瑞士）于1985年撰寫了首本飛行手冊《滑翔傘手冊》，創造了滑翔傘一詞。

1978年6月，來自法國上薩瓦省Mieussy的三個朋友Jean-ClaudeBétemps，AndréBohn和GérardBosson將這些發展合并在一起。在跳傘者和發行人丹·波因特（Dan Poynter）在《降落傘手冊》雜志上發表的一篇有關坡度飛漲的文章的靈感啟發之后，[7]他們計算出，在合適的坡度上，可以通過順著坡道向“方形”的沖壓空氣降落傘充氣； Bétemps從Mieussy的Pointe du Pertuiset發射升空100 m。博恩跟隨他，滑到1000米以下山谷的足球場。

In some modern paragliders (from the 1990s

onwards), especially higher-performance wings, some of the cells of the leading

edge are closed to form a cleaner aerodynamic profile. Holes in the internal

ribs allow a free flow of air from the open cells to these closed cells to

inflate them, and also to the wingtips, which are also closed.[13]

The pilot is supported underneath the wing

by a network of suspension lines. These start with two sets of risers made of

short (40 cm) lengths of strong webbing. Each set is attached to the harness by

a carabiner, one on each side of the pilot, and each riser of a set is generally

attached to lines from only one row of its side of wing. At the end of each

riser of the set, there is a small delta maillon with a number (2 – 5) of lines

attached, forming a fan. These are typically 4 – 5 metres long, with the end

attached to 2 ? 4 further lines of around 2 m, which are again joined to a

group of smaller, thinner lines. In some cases this is repeated for a fourth

cascade.

  對于普通喜愛戶外運動的人來說，經過滑翔傘教練的正規培訓，要獨自飛上藍天其實很easy.客觀的說，滑翔傘飛行是一項休閑航空運動，而非極限運動，只要身體無殘疾、無精神疾病、無癲癇、無心臟病、等疾病的大眾都可以參加.

      在歐洲的四億人中，注冊的滑翔傘飛行員已經達到兩百多萬人。而在中國13億人中，學習滑翔傘飛行的人少之又少，持有中航協頒發的滑翔傘飛行執照的飛行員，截止2019年5月才剛好一萬人。中國與歐洲甚至韓國日本的滑翔傘運動水平差距如此之大，是因為這項運動傳入中國大陸較晚，并且中國人的運動觀念保守，有點談“空”色變，只要是與飛行有關的運動，普通人都敬而遠之不敢嘗試。其實，滑翔傘運動在歐洲還被戲虐的稱之為“老頭樂”，七、八十歲仍然在飛滑翔傘的人大有人在，飛行對于他們，是一生不變的愛好。

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]
