About that time, David Barish was

developing the "sail wing" (single-surface wing) for recovery of NASA

space capsules – "slope soaring was a way of testing out ... the Sail

Wing."[5] After tests on Hunter Mountain, New York, in September 1965, he

went on to promote slope soaring as a summer activity for ski resorts.[6][7]


Author Walter Neumark wrote Operating

Procedures for Ascending Parachutes, and in 1973 he and a group of enthusiasts

with a passion for tow-launching PCs and ram-air parachutes broke away from the

British Parachute Association to form the British Association of Parascending Clubs

(which later became the British Hang Gliding and Paragliding Association). In

1997, Neumark was awarded the Gold Medal of the Royal Aero Club of the UK.

Authors Patrick Gilligan (Canada) and Bertrand Dubuis (Switzerland) wrote the

first flight manual, The Paragliding Manual in 1985, coining the word

paragliding.

滑翔傘是飛行滑翔傘的娛樂(lè)和競(jìng)爭(zhēng)性冒險(xiǎn)運(yùn)動(dòng):輕巧,自由飛行,腳踩滑翔機(jī),沒(méi)有剛性的基本結(jié)構(gòu)[1]。

飛行員坐在懸掛在機(jī)翼下方的安全帶中。

懸掛線,進(jìn)入機(jī)翼前部通風(fēng)孔的空氣壓力以及流過(guò)外部的空氣的空氣動(dòng)力保持了機(jī)翼的形狀。


盡管不使用發(fā)動(dòng)機(jī),滑翔傘飛行仍可持續(xù)數(shù)小時(shí),飛行數(shù)百公里,盡管更常見(jiàn)的是飛行一到兩個(gè)小時(shí),飛行數(shù)十公里。

通過(guò)熟練地利用升力源,飛行員可以增加身高,通常會(huì)爬升到幾千米的高度。


1954年,沃爾特·紐馬克(Walter

Neumark)預(yù)測(cè)(在《飛行》雜志上的一篇文章),滑翔機(jī)飛行員“能夠通過(guò)在懸崖邊緣或斜坡上奔跑來(lái)發(fā)動(dòng)自己……無(wú)論是在美國(guó)的攀巖假期中,

斯凱島或阿爾卑斯山滑雪?!?


1961年,法國(guó)工程師Pierre Lemongine制作了改進(jìn)的降落傘設(shè)計(jì),從而設(shè)計(jì)了Para-Commander。 PC的后部和側(cè)面均設(shè)有切口,可將其拖入空中并進(jìn)行操縱,從而實(shí)現(xiàn)滑翔傘運(yùn)動(dòng)。

多米娜·賈伯特(Domina Jalbert)發(fā)明了Parafoil,它具有呈翼型形狀的切片細(xì)胞。 敞開(kāi)式前緣和封閉式后緣,通過(guò)空氣而膨脹-沖壓空氣設(shè)計(jì)。 他于1963年1月10日提交了美國(guó)專(zhuān)利3131894。 嘉定區(qū)職業(yè)滑翔傘要多少錢(qián)


盡可能避免降落對(duì)機(jī)翼過(guò)大的風(fēng)。在接近預(yù)定著陸點(diǎn)的過(guò)程中,這種潛在問(wèn)題通常很明顯,并且可能有機(jī)會(huì)擴(kuò)大飛行范圍,以找到更庇護(hù)的著陸區(qū)域。在每次著陸時(shí),都希望機(jī)翼保持可飛行狀態(tài),并具有少量前向動(dòng)量。這使放氣更加可控。盡管中線(Bs)是垂直的,但是機(jī)翼快速順風(fēng)移動(dòng)的機(jī)會(huì)要少得多。常見(jiàn)的放氣提示來(lái)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(fēng),在后立管上保持壓力,并在機(jī)翼掉落時(shí)朝機(jī)翼輕快邁進(jìn)。通過(guò)實(shí)踐,有可能實(shí)現(xiàn)精確的安全“無(wú)故障停車(chē)”。


對(duì)于著陸進(jìn)場(chǎng)期間的強(qiáng)風(fēng),“拍打”機(jī)翼(制動(dòng)器對(duì)稱(chēng)脈動(dòng))是**終的常見(jiàn)選擇。它會(huì)降低機(jī)翼的升力性能。通過(guò)交替施加和釋放制動(dòng)器,下降速度大約每秒一次。該系統(tǒng)取決于飛行員對(duì)機(jī)翼的熟悉程度。機(jī)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(jìn)行安裝。通常,制造商會(huì)根據(jù)批準(zhǔn)重量范圍內(nèi)飛行員的平均身體比例來(lái)設(shè)定安全制動(dòng)行程范圍。應(yīng)該以小幅增加對(duì)該設(shè)置進(jìn)行更改,并在帶有說(shuō)明性標(biāo)記的情況下顯示這些變化,并進(jìn)行試飛以確認(rèn)所需的效果??s短制動(dòng)管路會(huì)產(chǎn)生使機(jī)翼變慢的問(wèn)題。過(guò)度加長(zhǎng)制動(dòng)器會(huì)使機(jī)翼難以達(dá)到安全的著陸速度。





Paragliders are unique among human-carrying

aircraft in being easily portable. The complete equipment packs into a rucksack

and can be carried easily on the pilot's back, in a car, or on public

transport.[14] In comparison with other air sports, this substantially

simplifies travel to a suitable takeoff spot, the selection of a landing place

and return travel.


Tandem paragliders, designed to carry the

pilot and one passenger, are larger but otherwise similar. They usually fly

faster with higher trim speeds, are more resistant to collapse, and have a

slightly higher sink rate compared to solo paragliders.



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.  南京專(zhuān)業(yè)滑翔傘便宜
