Europe has seen the greatest growth in

paragliding, with France alone registering in 2011 over 25,000 active pilots.

Wing

Cross section of a paraglider

Transverse cross section showing parts of a

paraglider:

1) upper surface

2) lower surface

3) rib

4) diagonal rib

5) upper line cascade

6) middle line cascade

7) lower line cascade

8) risers

The paraglider wing or canopy is usually

what is known in engineering as a "ram-air airfoil". Such wings

comprise two layers of fabric that are connected to internal supporting

material in such a way as to form a row of cells. By leaving most of the cells

open only at the leading edge, incoming air keeps the wing inflated, thus

maintaining its shape. When inflated, the wing's cross-section has the typical

teardrop aerofoil shape. Modern paraglider wings are made of high-performance

non-porous materials such as ripstop polyester[12] or nylon fabric.[note 1]

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]

Paragliders are unique among human-carrying

aircraft in being easily portable. The complete equipment packs into a rucksack

and can be carried easily on the pilot's back, in a car, or on public

transport.[14] In comparison with other air sports, this substantially

simplifies travel to a suitable takeoff spot, the selection of a landing place

and return travel.


Tandem paragliders, designed to carry the

pilot and one passenger, are larger but otherwise similar. They usually fly

faster with higher trim speeds, are more resistant to collapse, and have a

slightly higher sink rate compared to solo paragliders.



滑翔傘是飛行滑翔傘的娛樂和競爭性冒險運動:輕巧,自由飛行,腳踩滑翔機,沒有剛性的基本結構[1]。

飛行員坐在懸掛在機翼下方的安全帶中。

懸掛線,進入機翼前部通風孔的空氣壓力以及流過外部的空氣的空氣動力保持了機翼的形狀。


盡管不使用發動機,滑翔傘飛行仍可持續數小時,飛行數百公里,盡管更常見的是飛行一到兩個小時,飛行數十公里。

通過熟練地利用升力源,飛行員可以增加身高,通常會爬升到幾千米的高度。


1954年,沃爾特·紐馬克(Walter

Neumark)預測(在《飛行》雜志上的一篇文章),滑翔機飛行員“能夠通過在懸崖邊緣或斜坡上奔跑來發動自己……無論是在美國的攀巖假期中,

斯凱島或阿爾卑斯山滑雪。”


1961年,法國工程師Pierre Lemongine制作了改進的降落傘設計,從而設計了Para-Commander。 PC的后部和側面均設有切口,可將其拖入空中并進行操縱,從而實現滑翔傘運動。

多米娜·賈伯特(Domina Jalbert)發明了Parafoil,它具有呈翼型形狀的切片細胞。 敞開式前緣和封閉式后緣,通過空氣而膨脹-沖壓空氣設計。 他于1963年1月10日提交了美國專利3131894。

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.
