Paragliding is the recreational and competitive adventure sport of flying paragliders: lightweight, free-flying,

foot-launched glider aircraft with no rigid primary structure.[1] The pilot sits in a harness suspended below a fabric wing. Wing shape is maintained by the suspension lines, the pressure of air entering vents in the front of the wing, and the aerodynamic forces of the air flowing over the outside.

 Despite not using an engine, paragliderflights can last many hours and cover many hundreds of kilometres, though flights of one to two hours and covering some tens of kilometres are more the norm. By skillful exploitation of sources of lift, the pilot may gain height,

often climbing to altitudes of a few thousand metres.

安全


滑翔傘在巴西Araxá發(fā)射視頻

像任何極限運(yùn)動一樣,滑翔傘是一種潛在的危險(xiǎn)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(xiǎn)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(jì)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(xiǎn)。飛行員的安全受到對現(xiàn)場條件(如空氣湍流(轉(zhuǎn)子),強(qiáng)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(cuò)誤和飛行條件差的結(jié)果。

Harness

performing a reverse launch

The pilot is loosely and comfortably

buckled into a harness, which offers support in both the standing and sitting

positions. Most harnesses have foam or airbag protectors underneath the seat

and behind the back to reduce the impact on failed launches or landings. Modern

harnesses are designed to be as comfortable as a lounge chair in the sitting or

reclining position. Many harnesses even have an adjustable "lumbar

support". A reserve parachute is also typically connected to a paragliding

harness.


Harnesses also vary according to the need

of the pilot, and thereby come in a range of designs, mostly: Training harness

for beginners, Pax harness for tandem passengers that often also doubles as a

training harness, XC Harness for long distance cross country flights, All round

harness for basic to intermediate pilots, Pod harness, which is for

intermediate to pro pilots that focus on XC. Acro harnesses are special designs

for acrobatic pilots, Kids tandem harnesses are also now available with special

child-proof locks.


滑翔傘是一批熱愛跳傘、滑翔翼的飛行人員發(fā)明的一種飛行運(yùn)動,目前在歐美和日本等國非常流行,在中國臺灣也掀起了一股旋風(fēng)。滑翔傘與傳統(tǒng)的降落傘不同,它是一種飛行器。很久以前,人類為尋找一雙翅膀作過無數(shù)次的思考和探索。在古老的中國大地上,留下了像“駕車遨游太空”、“嫦娥奔月”等許多關(guān)于人類嘗試飛行的美好傳說。當(dāng)今,滑翔傘的誕生,為人類插上了飛翔的翅膀。人們自由地翱翔于天空,享受著“脫離”地球引力的寧靜與美妙.滑翔傘起源于20世紀(jì)70年代初的歐洲,當(dāng)時(shí),一些登山者從山上乘降落傘滑翔而**驗(yàn)到了一種美好的感覺和樂趣,從而創(chuàng)立了一個(gè)新興的航空體育項(xiàng)目。**初的滑翔傘是借鑒于飛機(jī)跳傘使用的翼型方傘,它主要以下降為主,下降速度快,安全性能好。通過二十多年的發(fā)展和演變。現(xiàn)在的滑翔傘**長飛行17小時(shí),**遠(yuǎn)飛行距離超過300公里,它體現(xiàn)了一種人與自然的交流,備受崇尚自然者的喜愛。


The glide ratio of paragliders ranges from

9.3 for recreational wings to about 11.3 for modern competition models,[16]

reaching in some cases up to 13.[17] For comparison, a typical skydiving

parachute will achieve about 3:1 glide. A hang glider ranges from 9.5 for

recreational wings to about 16.5 for modern competition models. An idling

(gliding) Cessna 152 light aircraft will achieve 9:1. Some sailplanes can

achieve a glide ratio of up to 72:1.


The speed range of paragliders is typically

20–75 kilometres per hour (12–47 mph), from stall speed to maximum speed.

Beginner wings will be in the lower part of this range, high-performance wings

in the upper part of the range.[note 2]


For storage and carrying, the wing is

usually folded into a stuffsack (bag), which can then be stowed in a large

backpack along with the harness. For pilots who may not want the added weight

or fuss of a backpack, some modern harnesses include the ability to turn the

harness inside out such that it becomes a backpack.

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]
