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]

This can be very dangerous, because now the

forces on the line have to be controlled by the moving object itself, which is

almost impossible to do, unless stretchy rope and a pressure/tension meter

(dynamometer) is used. Static line towing with stretchy rope and a load cell as

a tension meter has been used in Poland, Ukraine, Russia, and other Eastern

European countries for over twenty years (under the name Malinka) with about

the same safety record as other forms of towing.[21] One more form of towing is

hand towing. This is where 1?3 people pull a paraglider using a tow rope of up

to 500 feet. The stronger the wind, the fewer people are needed for a

successful hand tow.[22] Tows up to 300 feet have been accomplished, allowing

the pilot to get into a lift band of a nearby ridge or row of buildings and

ridge-soar in the lift the same way as with a regular foot launch.[23]

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.

滑翔傘在巴西Araxá發(fā)射視頻

像任何極限運動一樣,滑翔傘是一種潛在的危險活動。例如,在美國,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(有超過25,000名注冊機(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。飛行員的安全受到對現(xiàn)場條件(如空氣湍流(轉(zhuǎn)子),強熱,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誤和飛行條件差的結(jié)果。


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(jī)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(jī)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(jī)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(jī)的大耳朵通常會保持折疊狀態(tài)。在那種情況下,機(jī)翼可以大耳朵部署,以合理的安全降落。在那些機(jī)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(jī)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(jī)翼中時,機(jī)翼往往會對側(cè)傾軸上的重量變化(由于有效面積減小)產(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(jī)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(jī)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)。徐州口碑好滑翔傘價格合理

盡可能避免降落對機(jī)翼過大的風(fēng)。在接近預(yù)定著陸點的過程中,這種潛在問題通常很明顯,并且可能有機(jī)會擴(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,都希望機(jī)翼保持可飛行狀態(tài),并具有少量前向動量。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)移動的機(jī)會要少得多。常見的放氣提示來自后提升板管線(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)翼掉落時朝機(jī)翼輕快邁進(jìn)。通過實踐,有可能實現(xiàn)精確的安全“無故障停車”。


對于著陸進(jìn)場期間的強風(fēng),“拍打”機(jī)翼(制動器對稱脈動)是**終的常見選擇。它會降低機(jī)翼的升力性能。通過交替施加和釋放制動器,下降速度大約每秒一次。該系統(tǒng)取決于飛行員對機(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,制造商會根據(jù)批準(zhǔn)重量范圍內(nèi)飛行員的平均身體比例來設(shè)定安全制動行程范圍。應(yīng)該以小幅增加對該設(shè)置進(jìn)行更改,并在帶有說明性標(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短制動管路會產(chǎn)生使機(jī)翼變慢的問題。過度加長制動器會使機(jī)翼難以達(dá)到安全的著陸速度。
