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.

滑翔傘在“大耳朵”機(jī)動(dòng)
在不加速的情況下,正常飛行會(huì)拉動(dòng)外部A線,使翼尖向內(nèi)折疊,這將大大減小滑行角,而前進(jìn)速度*會(huì)小幅下降。隨著有效機(jī)翼面積的減小,機(jī)翼載荷增加,并且變得更加穩(wěn)定。但是,迎角增加了,飛行器更接近失速速度,但是可以通過應(yīng)用速度桿來改善,這也增加了下降速度。釋放管路時(shí),機(jī)翼會(huì)重新膨脹。如有必要,在制動(dòng)器上短暫抽氣有助于重新進(jìn)入正常飛行。與其他技術(shù)相比,機(jī)翼大了,機(jī)翼仍然向前滑動(dòng),這使飛行員可以離開危險(xiǎn)區(qū)域。例如,如果飛行員必須抵抗斜坡上的上升氣流,這種方式甚至可以降落。
B線失速
在B線停轉(zhuǎn)中,從前緣/前端起的第二組立管(B線)**于其他立管被下拉,其中特定的線用于啟動(dòng)停轉(zhuǎn)。這在翼上產(chǎn)生翼展方向的折痕,從而使氣流與翼的上表面分離。它顯著降低了頂篷產(chǎn)生的升力,從而導(dǎo)致更高的下降率。這可能是費(fèi)力的動(dòng)作,因?yàn)楸仨殞⑦@些B線保持在該位置,并且機(jī)翼的張力會(huì)在這些線上施加向上的力。必須小心處理這些線的釋放,以免引起機(jī)翼向前飛快射擊,然后飛行員可能掉入其中?,F(xiàn)在這已經(jīng)不那么流行了,因?yàn)樗跈C(jī)翼的內(nèi)部結(jié)構(gòu)上引起了高負(fù)荷。

滑翔傘錦標(biāo)賽開幕式在大明山舉行,來自國(guó)內(nèi)46名前列滑翔傘運(yùn)動(dòng)員參加此次錦標(biāo)賽。航空運(yùn)動(dòng)管理中心辦公室主任葉正福、自然保護(hù)區(qū)管理局滕達(dá)初副局長(zhǎng)參加開幕式并致辭。
葉正福表示,滑翔傘運(yùn)動(dòng),作為航空運(yùn)動(dòng)的重要項(xiàng)目之一,在我區(qū)起步雖晚,但發(fā)展勢(shì)頭強(qiáng)勁。近幾年,滑翔運(yùn)動(dòng)如雨后春筍般在八桂大地上發(fā)展壯大,處處開花。通過大家的不懈努力,現(xiàn)在,廣西的滑翔傘運(yùn)動(dòng)產(chǎn)業(yè)已初具規(guī)模。此次錦標(biāo)賽的舉辦,為發(fā)展我區(qū)滑翔運(yùn)動(dòng),提高我區(qū)滑翔運(yùn)動(dòng)競(jìng)技水平提供難得的機(jī)遇。
滕達(dá)初表示,本次賽事的舉辦,將極大促進(jìn)大明山“山地戶外運(yùn)動(dòng)”旅游品牌的打造,為塑造廣西大明山——“中國(guó)·東盟戶外運(yùn)動(dòng)中心”品牌助力。作為戶外運(yùn)動(dòng)會(huì)重要活動(dòng)之一的滑翔傘錦標(biāo)賽,也將打造廣西大明山航空旅游的新名片,進(jìn)一步提高廣西航空體育運(yùn)動(dòng)旅游、體育旅游的競(jìng)爭(zhēng)力,進(jìn)一步提高大明山**度,將大明山戶外運(yùn)動(dòng)聚集地形象推至全國(guó)乃至世界。
滑翔傘是飛行滑翔傘的娛樂和競(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,盡管更常見的是飛行一到兩個(gè)小時(shí),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(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“能夠通過在懸崖邊緣或斜坡上奔跑來發(fā)動(dòng)自己……無論是在美國(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。 敞開式前緣和封閉式后緣,通過空氣而膨脹-沖壓空氣設(shè)計(jì)。 他于1963年1月10日提交了美國(guó)專利3131894。
In 1952 Canadian Domina Jalbert patented a
governable gliding parachute with multi-cells and controls for lateral
glide.[2]
In 1954, Walter Neumark predicted (in an
article in Flight magazine) a time when a glider pilot would be "able to
launch himself by running over the edge of a cliff or down a slope ... whether
on a rock-climbing holiday in Skye or ski-ing in the Alps."[3]
In 1961, the French engineer Pierre
Lemongine produced improved parachute designs that led to the Para-Commander.
The PC had cutouts at the rear and sides that enabled it to be towed into the
air and steered, leading to parasailing/parascending.
Domina Jalbert invented the Parafoil, which
had sectioned cells in an aerofoil shape; an open leading edge and a closed
trailing edge, inflated by passage through the air – the ram-air design. He
filed US Patent 3131894 on January 10, 1963.[4]

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]
