Europe has seen the greatest growth in

paragliding, with France alone registering in 2011 over 25,000 active pilots.

The paraglider wing or canopy is usually

what is known in engineering as a "ram-air airfoil". Such wings

comprise two layers of fabric that are connected to internal supporting

material in such a way as to form a row of cells. By leaving most of the cells

open only at the leading edge, incoming air keeps the wing inflated, thus

maintaining its shape. When inflated, the wing's cross-section has the typical

teardrop aerofoil shape. Modern paraglider wings are made of high-performance

non-porous materials such as ripstop polyester[12] or nylon fabric.[note 1]

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.

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.

  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。

大风降落的替代方法包括使用速度杆和大耳朵。速度杆可增加机翼的穿透力，并增加垂直下降率的少量增加。这使得在正式电路中更容易调节下降率。在极端情况下，建议您在离开线束后站在速度杆上，并保持在速度杆上，直到着陆和放气为止。大耳朵通常在电路高度管理期间使用。垂直下降速度增加，并且可以利用该优点将滑翔机带到适当的电路连接高度。大多数制造商都在高级机型中改变了大耳朵的操作技术。放开控制线后，C级滑翔机的大耳朵通常会保持折叠状态。在那种情况下，机翼可以大耳朵部署，以合理的安全降落。在那些机翼类型中，通常需要两到三个带有制动器的对称泵，再过一到两秒钟才能重新给叶尖充气。在较低额定值的机翼中，“大耳朵”需要保持固定状态以将耳朵固定。当它们固定在机翼中时，机翼往往会对侧倾轴上的重量变化（由于有效面积减小）产生更好的响应。释放管线后，它们会自动重新充气。通常，这些机翼更适合拉入耳朵以摆脱多余高度的情况。然后应在基脚或着陆前几秒钟恢复全翼飞行。机翼熟悉度是应用这些控件的关键要素。飞行员应在中等条件下在安全区域，安全高度和有降落选项的情况下练习。苏州进口滑翔伞价格行情
