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.

在亚洲，日本、韩国、中国的中国台湾省等经济发达国家和地区的滑翔伞运动十分普及，爱好者达十多万人。20世纪80年代末，滑翔伞运动传入中国大陆并迅速发展，

现注册的航空俱乐部有50多个，正式会员1400多人，经常从事滑翔伞飞行者达数千人，在中国东北、长三角、珠三角长期有民间高手飞行，随着滑翔伞运动的逐渐普及，包括央视在内的很多电视媒体都对这一运动进行过专题报道。

滑翔伞通常主要由翼型伞衣、伞绳、背带系统和操纵系统四大部分组成。为便于滑翔伞的保管、携带与运输，每具滑翔伞还配有一只背式包装袋。

翼型伞衣，也称伞翼，是滑翔伞产生升力和承受载荷的主要部件。伞衣的形状、面积以及与气流相对运动的速度，对升力的产生有很大的影响。

翼型伞衣由上翼面、下翼面和沿翼展方向有规律分布的数十个成形翼肋构成。上下翼面与翼肋缝合，形成特定的伞翼形状。伞衣前缘按照翼肋的横向排列，构成一定尺寸的进气口。由于伞衣后缘是完全封闭的，所以上下翼面与各翼肋之间便形成了一个个用于储存空气的气室。 普陀区销售滑翔伞哪家好

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 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]
