每條線的頂部連接到縫在機翼結構中的小織物線圈上,這些織物線圈通常成行排列(即,左右)。**靠近前一行的行稱為A線,下一行稱為B線,依此類推。典型的機翼將具有A,B,C和D線,但是**近,有一種趨勢是將行的行數(shù)減少到三行,甚至兩行(并從實驗上減少到一行),以減少阻力。
滑翔傘線通常由迪尼瑪/光譜或凱夫拉爾/芳綸制成。盡管它們看起來很苗條,但這些材料非常堅固。例如,一條直徑為0.66毫的線(大約**細)可以具有56千克的斷裂強度。
滑翔傘的滑翔率范圍從休閑機翼的9.3到現(xiàn)代競賽模型的約11.3,在某些情況下高達13。為了進行比較,典型的跳傘降落傘將實現(xiàn)約3:1的滑行。懸掛式滑翔機的范圍從休閑機翼的9.5到現(xiàn)代競賽機型的約16.5??辙D(滑行)的塞斯納152輕型飛機將達到9:1。一些滑翔機可以實現(xiàn)高達72:1的滑行比。
滑翔傘的速度范圍通常為每小時20-75公里(12-47英里/小時),從失速速度到比較大速度。初學者機翼將位于該范圍的下部,高性能機翼將位于該范圍的上部。
為了存放和攜帶,機翼通常被折疊成一個行李袋,然后可以與安全帶一起存放在一個大背包中。對于可能不希望增加背包重量或煩惱的飛行員,一些現(xiàn)代安全帶具有將安全帶內翻的功能,從而使其成為背包。

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. 楊浦區(qū)專業(yè)滑翔傘詢問報價
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(fā)動機,滑翔傘飛行仍可持續(xù)數(shù)小時,飛行數(shù)百公里,盡管更常見的是飛行一到兩個小時,飛行數(shù)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(fā)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(xiàn)滑翔傘運動。

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

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.
Launching

Poland
A paraglider landing at Azheekkod beach,
India
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:

飛行中的機翼放氣(崩潰)
由于機翼(機翼)的形狀是由進入機翼并使之膨脹的運動空氣形成的,因此在湍流的空氣中,機翼的一部分或全部會收縮(塌陷)。被稱為“主動飛行”的飛行員技術將**降低通氣或坍塌的頻率和嚴重性。這種通縮通常無需飛行員干預即可恢復。如果發(fā)生嚴重的放氣,正確的飛行員輸入將加快從放氣中恢復的速度,但是錯誤的飛行員輸入會減慢滑翔機返回正常飛行的速度,因此飛行員必須進行正確的訓練和練習以應對放氣。
在極少數(shù)情況下,無法從通縮中恢復(或從諸如旋轉等其他威脅性狀況中)恢復過來的情況下,大多數(shù)飛行員會攜帶備用(救援,緊急情況)降落傘。但是,大多數(shù)飛行員從來沒有理由“扔”他們的儲備。如果機翼在低空發(fā)生放氣,即在起飛后不久或著陸前不久,機翼(滑翔傘)可能無法迅速恢復其正確的結構以防止發(fā)生,飛行員通常沒有足夠的剩余高度來部署后備力量降落傘[**小降落高度大約為60 m(200 ft),但通常在穩(wěn)定期使用120-180 m(390-590 ft)的高度進行典型部署]。備用降落傘的不同包裝方式會影響其部署時間。
