在亞洲,日本、韓國、中國的中國臺灣省等經(jīng)濟發(fā)達國家和地區(qū)的滑翔傘運動十分普及,愛好者達十多萬人。20世紀80年代末,滑翔傘運動傳入中國大陸并迅速發(fā)展,
現(xiàn)注冊的航空俱樂部有50多個,正式會員1400多人,經(jīng)常從事滑翔傘飛行者達數(shù)千人,在中國東北、長三角、珠三角長期有民間高手飛行,隨著滑翔傘運動的逐漸普及,包括央視在內(nèi)的很多電視媒體都對這一運動進行過專題報道。
滑翔傘通常主要由翼型傘衣、傘繩、背帶系統(tǒng)和操縱系統(tǒng)四大部分組成。為便于滑翔傘的保管、攜帶與運輸,每具滑翔傘還配有一只背式包裝袋。
翼型傘衣,也稱傘翼,是滑翔傘產(chǎn)生升力和承受載荷的主要部件。傘衣的形狀、面積以及與氣流相對運動的速度,對升力的產(chǎn)生有很大的影響。
翼型傘衣由上翼面、下翼面和沿翼展方向有規(guī)律分布的數(shù)十個成形翼肋構(gòu)成。上下翼面與翼肋縫合,形成特定的傘翼形狀。傘衣前緣按照翼肋的橫向排列,構(gòu)成一定尺寸的進氣口。由于傘衣后緣是完全封閉的,所以上下翼面與各翼肋之間便形成了一個個用于儲存空氣的氣室。 無錫小型滑翔傘價格如何計算
盡可能避免降落對機翼過大的風。在接近預(yù)定著陸點的過程中,這種潛在問題通常很明顯,并且可能有機會擴大飛行范圍,以找到更庇護的著陸區(qū)域。在每次著陸時,都希望機翼保持可飛行狀態(tài),并具有少量前向動量。這使放氣更加可控。盡管中線(Bs)是垂直的,但是機翼快速順風移動的機會要少得多。常見的放氣提示來自后提升板管線(Cs或Ds)上的劇烈拉力。迅速旋轉(zhuǎn)以迎面迎風,在后立管上保持壓力,并在機翼掉落時朝機翼輕快邁進。通過實踐,有可能實現(xiàn)精確的安全“無故障停車”。
對于著陸進場期間的強風,“拍打”機翼(制動器對稱脈動)是**終的常見選擇。它會降低機翼的升力性能。通過交替施加和釋放制動器,下降速度大約每秒一次。該系統(tǒng)取決于飛行員對機翼的熟悉程度。機翼不得停轉(zhuǎn)。應(yīng)在飛行中,安全高度,良好條件下,并由觀察員提供反饋的情況下,輕柔地進行安裝。通常,制造商會根據(jù)批準重量范圍內(nèi)飛行員的平均身體比例來設(shè)定安全制動行程范圍。應(yīng)該以小幅增加對該設(shè)置進行更改,并在帶有說明性標記的情況下顯示這些變化,并進行試飛以確認所需的效果??s短制動管路會產(chǎn)生使機翼變慢的問題。過度加長制動器會使機翼難以達到安全的著陸速度。

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:
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.

作者Walter Neumark撰寫了《降落傘操作程序》,并于1973年與一群對拖曳PC和ram-air降落傘充滿熱情的愛好者脫離了英國降落傘協(xié)會,成立了英國降落傘俱樂部協(xié)會(此協(xié)會后來成為英國的滑翔傘和滑翔傘協(xié)會)。 1997年,紐馬克(Neumark)被英國皇家航空俱樂部(Royal Aero Club)授予獎牌。作家Patrick Gilligan(加拿大)和Bertrand Dubuis(瑞士)于1985年撰寫了首本飛行手冊《滑翔傘手冊》,創(chuàng)造了滑翔傘一詞。
1978年6月,來自法國上薩瓦省Mieussy的三個朋友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》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。

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.
