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]

In

flatter countryside, pilots can also be launched with a tow. Once at full

height (towing can launch pilots up to 3000 feet altitude), the pilot pulls a

release cord, and the towline falls away. This requires separate training, as

flying on a winch has quite different characteristics from free flying. There

are two major ways to tow: pay-in and pay-out towing. Pay-in towing involves a

stationary winch that winds in the towline and thereby pulls the pilot in the

air. The distance between winch and pilot at the start is around 500 metres or

more. Pay-out towing involves a moving object, like a car or a boat, that pays

out line slower than the speed of the object, thereby pulling the pilot up in

the air. In both cases, it is very important to have a gauge indicating line

tension to avoid pulling the pilot out of the air. Another form of towing is

"static line" towing. This involves a moving object, like a car or a

boat, attached to a paraglider or hang glider with a fixed-length line. 連云港正規(guī)滑翔傘報(bào)價(jià)

大約在那個(gè)時(shí)候，大衛(wèi)·巴里什（David Barish）正在開發(fā)用于恢復(fù)NASA太空艙的“帆翼”（單面翼）-“高聳的斜坡是一種測(cè)試……帆翼的方法?！?在對(duì)Hunter進(jìn)行測(cè)試之后1965年9月，他在紐約的山上繼續(xù)推廣滑雪勝地的夏季活動(dòng)[6] [7]。

作者Walter Neumark撰寫了《降落傘操作程序》，并于1973年與一群對(duì)拖曳PC和ram-air降落傘充滿熱情的愛好者脫離了英國(guó)降落傘協(xié)會(huì)，成立了英國(guó)降落傘俱樂部協(xié)會(huì)（此協(xié)會(huì)后來成為英國(guó)的滑翔傘和滑翔傘協(xié)會(huì)）。 1997年，紐馬克（Neumark）被英國(guó)皇家航空俱樂部（Royal Aero Club）授予獎(jiǎng)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(cè)《滑翔傘手冊(cè)》，創(chuàng)造了滑翔傘一詞。

1978年6月，來自法國(guó)上薩瓦省Mieussy的三個(gè)朋友Jean-ClaudeBétemps，AndréBohn和GérardBosson將這些發(fā)展合并在一起。在跳傘者和發(fā)行人丹·波因特（Dan Poynter）在《降落傘手冊(cè)》雜志上發(fā)表的一篇有關(guān)坡度飛漲的文章的靈感啟發(fā)之后，[7]他們計(jì)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(fā)射升空100 m。博恩跟隨他，滑到1000米以下山谷的足球場(chǎng)。

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.

Reverse launches have a number of

advantages over a forward launch. It is more straightforward to inspect the

wing and check if the lines are free as it leaves the ground. In the presence

of wind, the pilot can be tugged toward the wing, and facing the wing makes it

easier to resist this force and safer in case the pilot slips (as opposed to

being dragged backwards). However, the movement pattern is more complex than

forward launch, and the pilot has to hold the brakes in a correct way and turn

to the correct side so he does not tangle the lines. These launches are

normally attempted with a reasonable wind speed, making the ground speed

required to pressurise the wing much lower.

The launch is initiated by the hands

raising the leading edge with the As. As it rises the wing is controlled more

by centring the feet than by use of the brakes or Cs. With mid level wings (EN

C and D) the wing may try to "overshoot" the pilot as it nears the

top. This is checked with Cs or brakes. The wing becomes increasingly sensitive

to the Cs and brakes as its internal air pressure rises.
