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]

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.

  对于普通喜爱户外运动的人来说，经过滑翔伞教练的正规培训，要独自飞上蓝天其实很easy.客观的说，滑翔伞飞行是一项休闲航空运动，而非极限运动，只要身体无残疾、无精神疾病、无癫痫、无心脏病、等疾病的大众都可以参加.

      在欧洲的四亿人中，注册的滑翔伞飞行员已经达到两百多万人。而在中国13亿人中，学习滑翔伞飞行的人少之又少，持有中航协颁发的滑翔伞飞行执照的飞行员，截止2019年5月才刚好一万人。中国与欧洲甚至韩国日本的滑翔伞运动水平差距如此之大，是因为这项运动传入中国大陆较晚，并且中国人的运动观念保守，有点谈“空”色变，只要是与飞行有关的运动，普通人都敬而远之不敢尝试。其实，滑翔伞运动在欧洲还被戏虐的称之为“老头乐”，七、八十岁仍然在飞滑翔伞的人大有人在，飞行对于他们，是一生不变的爱好。

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.

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. 徐州质量滑翔伞源头直供厂家
