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.

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]

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]
Paragliders are unique among human-carrying
aircraft in being easily portable. The complete equipment packs into a rucksack
and can be carried easily on the pilot's back, in a car, or on public
transport.[14] In comparison with other air sports, this substantially
simplifies travel to a suitable takeoff spot, the selection of a landing place
and return travel.
Tandem paragliders, designed to carry the
pilot and one passenger, are larger but otherwise similar. They usually fly
faster with higher trim speeds, are more resistant to collapse, and have a
slightly higher sink rate compared to solo paragliders.
滑翔伞完整的设备打包成背包,可以轻松地放在飞行员的后背,汽车或公共交通工具上。[14]与其他航空运动相比,这**简化了到达合适起飞点的行程,着陆地点的选择和返程行程。
双人滑翔伞设计用来载飞行员和一名乘客,虽然较大,但在其他方面相似。与单独的滑翔伞相比,它们通常以更高的修剪速度飞行得更快,更不易塌陷,并且下沉率略高。

飞行员可以轻松舒适地扣入安全带,该安全带可在站立和坐姿中提供支撑。大多数安全带在座椅下方和后方都有泡沫或安全气囊保护装置,以减少对失败的发射或着陆造成的影响。现代安全带的设计使其在坐姿或躺姿时都像躺椅一样舒适。许多背带甚至具有可调节的“腰部支撑”。备用降落伞通常也连接至滑翔伞背带。
线束也根据飞行员的需求而有所不同,因此设计范围很广,主要是:初学者的训练用安全带,双人旅客的Pax防护带(通常还兼用作训练用安全带),长距离越野飞行的XC线束, Pod线束,适用于基本至中级飞行员的全能线束,适用于专注于XC的中级至专业飞行员。杂技安全带是专为杂技飞行员设计的,儿童双人安全带现在也提供特殊的儿童防盗锁。

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。黄浦区**滑翔伞
