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]

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.

热飞行
托里·派恩斯滑翔伞在空中滑翔伞
当太阳温暖地面时,它将使某些功能比其他功能(例如岩石表面或大型建筑物)加热得更多,而这些功能会引发通过空气上升的热量。有时,这些可能只是空气的简单上升;通常,它们在风中向侧面吹,会从源头脱落,随后形成新的热量。
一旦飞行员找到了热量,他便开始绕圈飞行,试图将圆圈定位在热量**强的部分(“**”)上,其中空气的上升**快。大多数飞行员使用可变高度计(“ vario”),通过嘟嘟声和/或视觉显示来指示爬升率,以帮助将热量插入磁芯中。
通常情况下,周围的热源周围有很强的水槽,当飞行员试图进入强热源时,也存在强烈的湍流,导致机翼塌陷。良好的热力飞行是一项需要花费时间学习的技能,但是好的飞行员通常可以将热力一直贯穿到整个云层。
越野飞行
一旦掌握了使用热量来获得高度的技巧,飞行员就可以从一个热量滑到另一个热量来穿越国家。在热量中获得高度后,飞行员会下滑到下一个可用热量。
潜在的热量可以通过通常会产生热量的陆地特征或积云来识别,这些积云标志着上升的一列温暖,潮湿的空气在到达**并凝结成云时的顶部。
越野飞行员还需要熟悉航空法律,飞行法规,指示空域受限的航空地图等。

像任何极限运动一样,滑翔伞是一种潜在的危险活动。例如,在美国,2010年,一名滑翔伞飞行员死亡。这相当于5,000名飞行员中的一名。在1994-2010年间,每10,000名活跃的滑翔伞飞行员中平均有7人受到致命伤害,尽管近年来情况已有明显改善。在法国(有超过25,000名注册机员),2011年每10,000名飞行员中有2人受伤(这一比率并非2007-2011年的非典型),尽管每1,000名飞行员中约有6人受到严重伤害(超过2名飞行员,日间住院)。
通过培训和风险管理可以**减少伤害的可能性。使用适当的设备,例如为飞行员的身材和技能水平设计的机翼[28],以及头盔,备用降落伞[29]和缓冲式安全带[30],也可以很大程度地降低风险。飞行员的安全受到对现场条件(如空气湍流(转子),强热,狂风和地面障碍物,如电力线)的了解的影响。胜任的教练对机翼控制和紧急演习进行足够的飞行员培训可以很大程度地减少。许多滑翔伞是飞行员错误和飞行条件差的结果。
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 Kössen, Austria, in
1989.[10]

滑翔伞运动是一项崇尚自由、充满阳光的休闲娱乐运动,它能给人带来一种象鸟儿一样自由自在、驭风而行的感受。让山间清新的风,轻拂过我们的脸庞,飞翔在高山之上,蓝天之中,呼吸着清纯的空气,远离生活的烦恼和都市的喧嚣。让久已抑郁的心灵得到一次彻底的解放,俯瞰大地,林海莽莽,峰峦叠翠,尽收眼底。
滑翔伞运动也是一项包容性很强的飞行运动,从七八岁的孩子到六七十岁的老人都可以借助滑翔伞自由翱翔,也给喜欢挑战极限、超越自我的人带来了无限的**!所以滑翔伞运动广受喜爱。
一般的滑翔伞,它是慢速、轻柔、安静的,优雅地漂浮于空中,在温暖的阳光下、在和煦的风中飞行,它既是一项运动,也是一种游戏。如今,滑翔伞项目已被纳入2018年印尼亚运会项目,所以今年我们还可以通过电视一睹滑翔伞运动的风采以及滑翔伞飞行员比赛的精彩瞬间。
