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。

Radio
Radio communications are used in training,
to communicate with other pilots, and to report where and when they intend to
land. These radios normally operate on a range of frequencies in different
countries—some authorised,[18][19] some illegal but tolerated locally. Some
local authorities (e.g., flight clubs) offer periodic automated weather updates
on these frequencies. In rare cases, pilots use radios to talk to airport
control towers or air traffic controllers. Many pilots carry a cell phone so
they can call for pickup should they land away from their intended point of
destination.
GPS
GPS (global positioning system) is a
necessary accessory when flying competitions, where it has to be demonstrated
that way-points have been correctly passed. The recorded GPS track of a flight
can be used to analyze flying technique or can be shared with other pilots. GPS
is also used to determine drift due to the prevailing wind when flying at
altitude, providing position information to allow restricted airspace to be
avoided and identifying one's location for retrieval teams after landing out in
unfamiliar territory. 南通销售滑翔伞全国发货
The top of each line is attached to small
fabric loops sewn into the structure of the wing, which are generally arranged
in rows running span-wise (i.e., side to side). The row of lines nearest the
front are known as the A lines, the next row back the B lines, and so on.[14] A
typical wing will have A, B, C and D lines, but recently, there has been a
tendency to reduce the rows of lines to three, or even two (and experimentally
to one), to reduce drag.
Paraglider lines are usually made from
Dyneema/Spectra or Kevlar/Aramid.[14] Although they look rather slender, these
materials are immensely strong. For example, a single 0.66 mm-diameter line
(about the thinnest used) can have a breaking strength of 56 kg.[15]
Paraglider wings typically have an area of
20–35 square metres (220–380 sq ft) with a span of 8–12 metres (26–39 ft) and
weigh 3–7 kilograms (6.6–15.4 lb). Combined weight of wing, harness, reserve,
instruments, helmet, etc. is around 12–22 kilograms (26–49 lb).
尽可能避免降落对机翼过大的风。在接近预定着陆点的过程中,这种潜在问题通常很明显,并且可能有机会扩大飞行范围,以找到更庇护的着陆区域。在每次着陆时,都希望机翼保持可飞行状态,并具有少量前向动量。这使放气更加可控。尽管中线(Bs)是垂直的,但是机翼快速顺风移动的机会要少得多。常见的放气提示来自后提升板管线(Cs或Ds)上的剧烈拉力。迅速旋转以迎面迎风,在后立管上保持压力,并在机翼掉落时朝机翼轻快迈进。通过实践,有可能实现精确的安全“无故障停车”。
对于着陆进场期间的强风,“拍打”机翼(制动器对称脉动)是**终的常见选择。它会降低机翼的升力性能。通过交替施加和释放制动器,下降速度大约每秒一次。该系统取决于飞行员对机翼的熟悉程度。机翼不得停转。应在飞行中,安全高度,良好条件下,并由观察员提供反馈的情况下,轻柔地进行安装。通常,制造商会根据批准重量范围内飞行员的平均身体比例来设定安全制动行程范围。应该以小幅增加对该设置进行更改,并在带有说明性标记的情况下显示这些变化,并进行试飞以确认所需的效果。缩短制动管路会产生使机翼变慢的问题。过度加长制动器会使机翼难以达到安全的着陆速度。

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。

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. 松江区职业滑翔伞新报价
