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.

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]

The top of each line is attached to small

fabric loops sewn into the structure of the wing, which are generally arranged

in rows running span-wise (i.e., side to side). The row of lines nearest the

front are known as the A lines, the next row back the B lines, and so on.[14] A

typical wing will have A, B, C and D lines, but recently, there has been a

tendency to reduce the rows of lines to three, or even two (and experimentally

to one), to reduce drag.

Paraglider lines are usually made from

Dyneema/Spectra or Kevlar/Aramid.[14] Although they look rather slender, these

materials are immensely strong. For example, a single 0.66 mm-diameter line

(about the thinnest used) can have a breaking strength of 56 kg.[15]

Paraglider wings typically have an area of

20–35 square metres (220–380 sq ft) with a span of 8–12 metres (26–39 ft) and

weigh 3–7 kilograms (6.6–15.4 lb). Combined weight of wing, harness, reserve,

instruments, helmet, etc. is around 12–22 kilograms (26–49 lb).

Launching

As with all aircraft, launching and landing

are done into wind. The wing is placed into an airstream, either by running or

being pulled, or an existing wind. The wing moves up over the pilot into a

position in which it can carry the passenger. The pilot is then lifted from the

ground and, after a safety period, can sit down into his harness. Unlike

skydivers, paragliders, like hang gliders, do not "jump" at any time

during this process. There are two launching techniques used on higher

ground[20] and one assisted launch technique used in flatland areas:

The next step in the launch is to bring the

wing into the lift zone. There are two techniques for accomplishing this

depending on wind conditions. In light wind this is usually done after turning

to the front, steering with the feet towards the low wing tip, and applying

light brakes in a natural sense to keep the wing horizontal. In stronger wind

conditions it is often found to be easier to remain facing downwind while

moving slowly and steadily backwards into the wind.

Knees bent to load the wing, foot

adjustments to remain central and minimum use of Cs or Brakes to keep the wing

horizontal. Pirouette when the feet are close to lifting. This option has two

distinct advantages. a) The pilot can see the wing centre marker (an aid to

centring the feet) and, if necessary, b) the pilot can move briskly towards the

wing to assist with an emergency deflation.

With either method it is essential to check

"traffic" across the launch face before committing to flight.

滑翔傘是一批熱愛跳傘、滑翔翼的飛行人員發明的一種飛行運動，目前在歐美和日本等國非常流行，在中國臺灣也掀起了一股旋風。滑翔傘與傳統的降落傘不同，它是一種飛行器。很久以前，人類為尋找一雙翅膀作過無數次的思考和探索。在古老的中國大地上，留下了像“駕車遨游太空”、“嫦娥奔月”等許多關于人類嘗試飛行的美好傳說。當今，滑翔傘的誕生，為人類插上了飛翔的翅膀。人們自由地翱翔于天空，享受著“脫離”地球引力的寧靜與美妙.滑翔傘起源于20世紀70年代初的歐洲，當時，一些登山者從山上乘降落傘滑翔而**驗到了一種美好的感覺和樂趣，從而創立了一個新興的航空體育項目。**初的滑翔傘是借鑒于飛機跳傘使用的翼型方傘，它主要以下降為主，下降速度快，安全性能好。通過二十多年的發展和演變。現在的滑翔傘**長飛行17小時，**遠飛行距離超過300公里，它體現了一種人與自然的交流，備受崇尚自然者的喜愛。崇明區正規滑翔傘廠家報價
