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. 徐州銷售滑翔傘報價
大風(fēng)降落的替代方法包括使用速度桿和大耳朵。速度桿可增加機翼的穿透力,并增加垂直下降率的少量增加。這使得在正式電路中更容易調(diào)節(jié)下降率。在極端情況下,建議您在離開線束后站在速度桿上,并保持在速度桿上,直到著陸和放氣為止。大耳朵通常在電路高度管理期間使用。垂直下降速度增加,并且可以利用該優(yōu)點將滑翔機帶到適當(dāng)?shù)碾娐愤B接高度。大多數(shù)制造商都在高級機型中改變了大耳朵的操作技術(shù)。放開控制線后,C級滑翔機的大耳朵通常會保持折疊狀態(tài)。在那種情況下,機翼可以大耳朵部署,以合理的安全降落。在那些機翼類型中,通常需要兩到三個帶有制動器的對稱泵,再過一到兩秒鐘才能重新給葉尖充氣。在較低額定值的機翼中,“大耳朵”需要保持固定狀態(tài)以將耳朵固定。當(dāng)它們固定在機翼中時,機翼往往會對側(cè)傾軸上的重量變化(由于有效面積減?。┊a(chǎn)生更好的響應(yīng)。釋放管線后,它們會自動重新充氣。通常,這些機翼更適合拉入耳朵以擺脫多余高度的情況。然后應(yīng)在基腳或著陸前幾秒鐘恢復(fù)全翼飛行。機翼熟悉度是應(yīng)用這些控件的關(guān)鍵要素。飛行員應(yīng)在中等條件下在安全區(qū)域,安全高度和有降落選項的情況下練習(xí)。浦東新區(qū)官方滑翔傘全國發(fā)貨
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。
The next step in the launch is to bring the
wing into the lift zone. There are two techniques for accomplishing this
depending on wind conditions. In light wind this is usually done after turning
to the front, steering with the feet towards the low wing tip, and applying
light brakes in a natural sense to keep the wing horizontal. In stronger wind
conditions it is often found to be easier to remain facing downwind while
moving slowly and steadily backwards into the wind.
Knees bent to load the wing, foot
adjustments to remain central and minimum use of Cs or Brakes to keep the wing
horizontal. Pirouette when the feet are close to lifting. This option has two
distinct advantages. a) The pilot can see the wing centre marker (an aid to
centring the feet) and, if necessary, b) the pilot can move briskly towards the
wing to assist with an emergency deflation.
With either method it is essential to check
"traffic" across the launch face before committing to flight.
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(nèi)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(yīng)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(shù)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(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(nèi)部結(jié)構(gòu)上引起了高負荷。

Land-based practice: Kiting
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.
