滑翔伞在巴西Araxá发射视频
像任何极限运动一样,滑翔伞是一种潜在的危险活动。例如,在美国,2010年,一名滑翔伞飞行员死亡。这相当于5,000名飞行员中的一名。在1994-2010年间,每10,000名活跃的滑翔伞飞行员中平均有7人受到致命伤害,尽管近年来情况已有明显改善。在法国(有超过25,000名注册机员),2011年每10,000名飞行员中有2人受伤(这一比率并非2007-2011年的非典型),尽管每1,000名飞行员中约有6人受到严重伤害(超过2名飞行员,日间住院)。
通过培训和风险管理可以**减少伤害的可能性。使用适当的设备,例如为飞行员的身材和技能水平设计的机翼[28],以及头盔,备用降落伞[29]和缓冲式安全带[30],也可以很大程度地降低风险。飞行员的安全受到对现场条件(如空气湍流(转子),强热,狂风和地面障碍物,如电力线)的了解的影响。胜任的教练对机翼控制和紧急演习进行足够的飞行员培训可以很大程度地减少。许多滑翔伞是飞行员错误和飞行条件差的结果。

滑翔伞的机翼或机盖通常在工程上称为“冲压空气翼型”。这样的翼包括两层织物,它们以形成一排网孔的方式连接到内部支撑材料上。通过使大多数舱室*在前缘处敞开,进入的空气使机翼保持充气状态,从而保持其形状。充气时,机翼的横截面具有典型的泪滴翼型形状。现代滑翔伞的机翼是由高性能的无孔材料制成的,例如尼龙纤维。
在某些现代滑翔伞(从1990年开始中,尤其是性能更高的机翼中,前缘的某些舱室被封闭以形成更干净的空气动力学轮廓。内部肋骨上的孔允许空气从开孔到这些闭孔的自由流动,以使它们膨胀,并向也闭合的翼尖膨胀。
飞行员通过悬吊线网络支撑在机翼下方。这些从两根短的(40厘米)长的坚固织带制成的立管开始。每组由一个登山扣固定在吊带上,飞行员的每一侧上各有一个,每个组的立管通常*从机翼一侧的一行上连接到绳索上。在该组的每个立管的末端,都有一个小三角洲的马龙,上面挂有数行(2 – 5)条线,形成一个风扇。这些线通常长4 – 5米,末端连接到大约2 m的另外2 – 4条线上,这些线又连接到一组更细的细线上。在某些情况下,对第四级联重复此操作。

Harness
A pilot with harness (light blue),
performing a reverse launch
The pilot is loosely and comfortably
buckled into a harness, which offers support in both the standing and sitting
positions. Most harnesses have foam or airbag protectors underneath the seat
and behind the back to reduce the impact on failed launches or landings. Modern
harnesses are designed to be as comfortable as a lounge chair in the sitting or
reclining position. Many harnesses even have an adjustable "lumbar
support". A reserve parachute is also typically connected to a paragliding
harness.
Harnesses also vary according to the need
of the pilot, and thereby come in a range of designs, mostly: Training harness
for beginners, Pax harness for tandem passengers that often also doubles as a
training harness, XC Harness for long distance cross country flights, All round
harness for basic to intermediate pilots, Pod harness, which is for
intermediate to pro pilots that focus on XC. Acro harnesses are special designs
for acrobatic pilots, Kids tandem harnesses are also now available with special
child-proof locks.
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.
Forward launch
In low winds, the wing is inflated with a
forward launch, where the pilot runs forward with the wing behind so that the
air pressure generated by the forward movement inflates the wing.
It is often easier, because the pilot only
has to run forward, but the pilot cannot see his wing until it is above him,
where he has to check it in a very short time for correct inflation and
untangled lines before the launch.
Reverse launch

Paraglider reverse launch, Mam Tor, England
In higher winds, a reverse launch is used,
with the pilot facing the wing to bring it up into a flying position, then
turning around under the wing and running to complete the launch.

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).

条形码扫描器利用光电元件将检测到的光信号转换成电信号,再将电信号通过模拟数字转换器转化为数字信号传输到计算机中处理。对于一维条形码扫描器,如激光型、影像型扫描器,扫描器都通过从某个角度将光束发射到标签上并接收其反射回来的光线读取条形码信息,因此,在读取条形码信息时,光线要与条形码呈一个倾斜角度,这样,整个光束就会产生漫反射,可以将模拟波形转换成数字波形。如果光线与条形码垂直照射,则会导致一部分模拟波形过高而不能正常地转换成数字波形,从而无法读取信息。不锈钢条码标签制作工艺。江苏医用金属条码批量定制条码条形码技术(barcodetechnology,BCT)是在计算机的应用实践中产生和发展起来的...
