滑翔傘在巴西Araxá發(fā)射視頻

像任何極限運(yùn)動(dòng)一樣,滑翔傘是一種潛在的危險(xiǎn)活動(dòng)。例如,在美國(guó),2010年,一名滑翔傘飛行員死亡。這相當(dāng)于5,000名飛行員中的一名。在1994-2010年間,每10,000名活躍的滑翔傘飛行員中平均有7人受到致命傷害,盡管近年來情況已有明顯改善。在法國(guó)(有超過25,000名注冊(cè)機(jī)員),2011年每10,000名飛行員中有2人受傷(這一比率并非2007-2011年的非典型),盡管每1,000名飛行員中約有6人受到嚴(yán)重傷害(超過2名飛行員,日間住院)。


通過培訓(xùn)和風(fēng)險(xiǎn)管理可以**減少傷害的可能性。使用適當(dāng)?shù)脑O(shè)備,例如為飛行員的身材和技能水平設(shè)計(jì)的機(jī)翼[28],以及頭盔,備用降落傘[29]和緩沖式安全帶[30],也可以很大程度地降低風(fēng)險(xiǎn)。飛行員的安全受到對(duì)現(xiàn)場(chǎng)條件(如空氣湍流(轉(zhuǎn)子),強(qiáng)熱,狂風(fēng)和地面障礙物,如電力線)的了解的影響。勝任的教練對(duì)機(jī)翼控制和緊急演習(xí)進(jìn)行足夠的飛行員培訓(xùn)可以很大程度地減少。許多滑翔傘是飛行員錯(cuò)誤和飛行條件差的結(jié)果。

In some modern paragliders (from the 1990s

onwards), especially higher-performance wings, some of the cells of the leading

edge are closed to form a cleaner aerodynamic profile. Holes in the internal

ribs allow a free flow of air from the open cells to these closed cells to

inflate them, and also to the wingtips, which are also closed.[13]


The pilot is supported underneath the wing

by a network of suspension lines. These start with two sets of risers made of

short (40 cm) lengths of strong webbing. Each set is attached to the harness by

a carabiner, one on each side of the pilot, and each riser of a set is generally

attached to lines from only one row of its side of wing. At the end of each

riser of the set, there is a small delta maillon with a number (2 – 5) of lines

attached, forming a fan. These are typically 4 – 5 metres long, with the end

attached to 2 ? 4 further lines of around 2 m, which are again joined to a

group of smaller, thinner lines. In some cases this is repeated for a fourth

cascade.



飛行中的機(jī)翼放氣(崩潰)

由于機(jī)翼(機(jī)翼)的形狀是由進(jìn)入機(jī)翼并使之膨脹的運(yùn)動(dòng)空氣形成的,因此在湍流的空氣中,機(jī)翼的一部分或全部會(huì)收縮(塌陷)。被稱為“主動(dòng)飛行”的飛行員技術(shù)將**降低通氣或坍塌的頻率和嚴(yán)重性。這種通縮通常無需飛行員干預(yù)即可恢復(fù)。如果發(fā)生嚴(yán)重的放氣,正確的飛行員輸入將加快從放氣中恢復(fù)的速度,但是錯(cuò)誤的飛行員輸入會(huì)減慢滑翔機(jī)返回正常飛行的速度,因此飛行員必須進(jìn)行正確的訓(xùn)練和練習(xí)以應(yīng)對(duì)放氣。


在極少數(shù)情況下,無法從通縮中恢復(fù)(或從諸如旋轉(zhuǎn)等其他威脅性狀況中)恢復(fù)過來的情況下,大多數(shù)飛行員會(huì)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(chǔ)備。如果機(jī)翼在低空發(fā)生放氣,即在起飛后不久或著陸前不久,機(jī)翼(滑翔傘)可能無法迅速恢復(fù)其正確的結(jié)構(gòu)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(jìn)行典型部署]。備用降落傘的不同包裝方式會(huì)影響其部署時(shí)間。



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。 靜安區(qū)**滑翔傘價(jià)格如何計(jì)算

A paragliding flight over the Mussel Rock

Gliding Bluffs in Pacifica, California

In

flatter countryside, pilots can also be launched with a tow. Once at full

height (towing can launch pilots up to 3000 feet altitude), the pilot pulls a

release cord, and the towline falls away. This requires separate training, as

flying on a winch has quite different characteristics from free flying. There

are two major ways to tow: pay-in and pay-out towing. Pay-in towing involves a

stationary winch that winds in the towline and thereby pulls the pilot in the

air. The distance between winch and pilot at the start is around 500 metres or

more. Pay-out towing involves a moving object, like a car or a boat, that pays

out line slower than the speed of the object, thereby pulling the pilot up in

the air. In both cases, it is very important to have a gauge indicating line

tension to avoid pulling the pilot out of the air. Another form of towing is

"static line" towing. This involves a moving object, like a car or a

boat, attached to a paraglider or hang glider with a fixed-length line. 嘉定區(qū)職業(yè)滑翔傘多少錢
