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.  無錫質(zhì)量滑翔傘好貨源好價(jià)格

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]

無動(dòng)力滑翔傘是借助傘翼在空中相對(duì)空氣的運(yùn)動(dòng)產(chǎn)生的升力，由飛行員通過操縱繩控制速度、方向等，實(shí)現(xiàn)無動(dòng)力滑翔傘自由翱翔的。它起源于法國(guó)，于上世紀(jì)八十年代傳入中國(guó)，截至目前，國(guó)內(nèi)的持證滑翔傘飛行員剛剛過萬人，是極富魅力與想象力并且很厲害的潮人運(yùn)動(dòng)。

      請(qǐng)記住，滑翔傘不是降落傘，降落傘是“可展式氣動(dòng)阻力器”，它能讓人或物體從空中以較小的勻速下降。而滑翔傘是人類目前創(chuàng)造出的簡(jiǎn)易的飛行器，它能借助對(duì)流層中的熱氣流越飛越高，直到云底或者熱氣流消散的積云頂端。

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]
