Safety and regulations
Research estimates that the activity is
slightly safer (per event) than riding motorcycles and more dangerous than
riding in cars.[3] The most likely cause of serious injury is body contact with
a spinning propeller. The next most likely cause of injury is flying into
something other than the landing zone.[4] Some pilots carry a reserve parachute
designed to open in as little as 50 ft (15 m).
The lack of established design criteria for
these aircraft led the British Air Accidents Investigation Branch to conclude
in 2007 that "Only when precise reserve factors have been established for
individual harness/wing combinations carrying realistic suspended masses, at
load factors appropriate to the maneuvers to be carried out, can these aircraft
be considered to be structurally safe"[5]
济南培训动力伞什么条件
动力滑翔伞(“ PPG”)的线束和推进部分的总称。动力伞有两种基本类型:脚踏发动和车轮发动。
脚踏模型由带线束,油箱,发动机和螺旋桨的框架组成。带有防护网的铁环主要是将管线保持在螺旋桨之外。该装置就像一个大背包一样穿着,滑翔伞通过安全扣固定在大背包上。
车轮发射装置既可以作为带有自己的电动机的完整装置来提供,也可以作为脚踏发射动力装置的附加装置来提供。他们通常有3个(三轮车)或4个(四轮)车轮,可容纳一两个乘客。这些不应与动力降落伞相混淆,动力降落伞通常重得多,功率更大并且具有不同的操纵方向。
这个词**初是由英国人麦克·拜恩(Mike Byrne)在1980年使用的[1],并在1986年左右的法国流行起来,当时拉穆埃(La Mouette)开始为当时的新滑翔伞机翼调整动力。

噪声
相对于观察者的动力伞噪声取决于动力装置的距离,响度,频率和音质。大部分噪音来自螺旋桨,而缓慢的转速被认为是**安静的。飞行员可以通过将噪声敏感的区域保持在低功率状态来减轻其声音影响,将实际距离保持在**远的位置,并减少在该区域附近所花费的时间。
执照和培训
在美国,英国或许多其他国家,既不需要许可证,也不需要特定的培训。在没有特别规定的地方(例如墨西哥),只要飞行员在适当的情况下与当地官员合作,就可以容许滑翔伞飞行。[需要引用]在存在特别规定的国家(例如加拿**国,意大利和南非),飞行员必须由执照的教练进行飞行理论和实践方面的培训。一些需要正式认证的国家经常通过非**的超轻航空组织进行认证。
无论法规如何,如果没有经过适当培训,进行动力滑翔伞运动都是很危险的。
对于飞行员来说,要通过大多数组织的完整飞行员教学大纲,需要5到15天的时间,由于天气原因,这可能需要更长的日历时间。教学中使用了许多技巧,尽管大多数技巧包括让学生熟悉在地面上,通过牵引,小山丘或串列飞行时如何操纵机翼。
借助特殊装备,可以乘搭乘客(双人),但是大多数国家(包括美国)都需要某种形式的证明。
This sport has evolved and now many
advanced pilots perform extreme maneuvers such as wing-overs, barrel rolls and
loops. These types of maneuvers present a significant danger as any type of
negative G's encountered will unload the wing allowing the wings lines to go
slack. Only very advanced pilots with years of experience, training and coupled
with countermeasures such as reserve parachutes should attempt such maneuvers.
A reserve parachute is a highly recommended piece of equipment which may
prevent significant injury or death in the presence of a malfunction of the
equipment or a mistake made by the pilot.
Powered paragliding, also known as
paramotoring or PPG, is a form of ultralight aviation where the pilot wears a
back-mounted motor (a paramotor) which provides enough thrust to take off using
a paraglider. It can be launched in still air, and on level ground, by the
pilot alone — no assistance is required.
The term was first used by Englishman Mike
Byrne in 1980[1] and popularized in France around 1986 when La Mouette began
adapting power to the then-new paraglider wings.
Power plants are almost exclusively small
two-stroke internal combustion engines, between 80 cc and 350 cc, that burn a
mixture of gasoline and oil. These engines are favored for their quick high
r.p.m. thrust and low weight, using approximately 3.7 litres (1 US Gal.) of
fuel per hour depending on paraglider efficiency, the weight of unit plus
pilot, and flying weather conditions. At least one manufacturer is producing a
4-stroke model favored for its strong lower r.p.m. thrust and better fuel
efficiency. Electrically powered units also exist, though flight duration is
considerably limited on the battery's electrical capacity. Csaba Lemak created
the first electric PPG, flying it first on 13 June 2006.[2][3] Wankel rotary
engined paramotors are also available, but rare.

Paramotor is the generic name for the
harness and propulsive portion of a powered paraglider ("PPG"). There
are two basic types of paramotors: foot launch and wheel launch.
Foot launch models consist of a frame with
harness, fuel tank, engine, and propeller. A hoop with protective netting
primarily keeps lines out of the propeller. The unit is worn like a large
backpack to which a Paraglider is attached through carabiners.
Wheel launch units either come as complete
units with their own motor, or as an add-on to a foot launch paramotor. They
usually have 3 (trike) or 4 (quad) wheels, with seats for one or two occupants.
These should not be confused with Powered Parachutes which are generally much
heavier, more powerful, and have different steering.
