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”機動
在不加速的情況下,正常飛行會拉動外部A線,使翼尖向內折疊,這將大大減小滑行角,而前進速度*會小幅下降。隨著有效機翼面積的減小,機翼載荷增加,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,但是可以通過應用速度桿來改善,這也增加了下降速度。釋放管路時,機翼會重新膨脹。如有必要,在制動器上短暫抽氣有助于重新進入正常飛行。與其他技術相比,機翼大了,機翼仍然向前滑動,這使飛行員可以離開危險區(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停轉。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,從而導致更高的下降率。這可能是費力的動作,因為必須將這些B線保持在該位置,并且機翼的張力會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,因為它在機翼的內部結構上引起了高負荷。

滑翔傘錦標賽開幕式在大明山舉行,來自國內46名前列滑翔傘運動員參加此次錦標賽。航空運動管理中心辦公室主任葉正福、自然保護區(qū)管理局滕達初副局長參加開幕式并致辭。
葉正福表示,滑翔傘運動,作為航空運動的重要項目之一,在我區(qū)起步雖晚,但發(fā)展勢頭強勁。近幾年,滑翔運動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,廣西的滑翔傘運動產(chǎn)業(yè)已初具規(guī)模。此次錦標賽的舉辦,為發(fā)展我區(qū)滑翔運動,提高我區(qū)滑翔運動競技水平提供難得的機遇。
滕達初表示,本次賽事的舉辦,將極大促進大明山“山地戶外運動”旅游品牌的打造,為塑造廣西大明山——“中國·東盟戶外運動中心”品牌助力。作為戶外運動會重要活動之一的滑翔傘錦標賽,也將打造廣西大明山航空旅游的新名片,進一步提高廣西航空體育運動旅游、體育旅游的競爭力,進一步提高大明山**度,將大明山戶外運動聚集地形象推至全國乃至世界。
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。
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胞。 敞開式前緣和封閉式后緣,通過空氣而膨脹-沖壓空氣設計。 他于1963年1月10日提交了美國專利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]
