无动力滑翔伞是借助伞翼在空中相对空气的运动产生的升力,由飞行员通过操纵绳控制速度、方向等,实现无动力滑翔伞自由翱翔的。它起源于法国,于上世纪八十年代传入中国,截至目前,国内的持证滑翔伞飞行员刚刚过万人,是极富魅力与想象力并且很厉害的潮人运动。
请记住,滑翔伞不是降落伞,降落伞是“可展式气动阻力器”,它能让人或物体从空中以较小的匀速下降。而滑翔伞是人类目前创造出的简易的飞行器,它能借助对流层中的热气流越飞越高,直到云底或者热气流消散的积云顶端。 金山区自动滑翔伞新报价
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
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.
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.
滑翔伞在“大耳朵”机动
在不加速的情况下,正常飞行会拉动外部A线,使翼尖向内折叠,这将大大减小滑行角,而前进速度*会小幅下降。随着有效机翼面积的减小,机翼载荷增加,并且变得更加稳定。但是,迎角增加了,飞行器更接近失速速度,但是可以通过应用速度杆来改善,这也增加了下降速度。释放管路时,机翼会重新膨胀。如有必要,在制动器上短暂抽气有助于重新进入正常飞行。与其他技术相比,机翼大了,机翼仍然向前滑动,这使飞行员可以离开危险区域。例如,如果飞行员必须抵抗斜坡上的上升气流,这种方式甚至可以降落。
B线失速
在B线停转中,从前缘/前端起的第二组立管(B线)**于其他立管被下拉,其中特定的线用于启动停转。这在翼上产生翼展方向的折痕,从而使气流与翼的上表面分离。它显着降低了顶篷产生的升力,从而导致更高的下降率。这可能是费力的动作,因为必须将这些B线保持在该位置,并且机翼的张力会在这些线上施加向上的力。必须小心处理这些线的释放,以免引起机翼向前飞快射击,然后飞行员可能掉入其中。现在这已经不那么流行了,因为它在机翼的内部结构上引起了高负荷。
