A powered paraglider differs from a powered
parachute (PPC) primarily in size, power, control method, and number of
occupants. Powered paragliders are smaller, use more efficient (but more
difficult to manage) paraglider wings, and steer with brake toggles like sport
parachutists. Powered parachutes typically use easier-to-manage but less
efficient wings, have larger engines, steer with their feet, and may be able to
take along passengers. There are exceptions; a growing number of powered
parachutes use elliptical wings, some use hand controls, and many are light
single seat aircraft that meet FAA Part 103 requirements.

Noise
Paramotor noise relative to an observer
depends on distance, loudness, frequency and timbre of the power unit. Most
noise comes from the propeller and slow rpm is perceived as the quietest.
Pilots mitigate their sound impact by leaving a noise-sensitive area at low
power, keeping the farthest practical distance away, and reducing time spent
near the area.
License and training
Neither a license nor specific training is
required in the U.S., U.K. or many other countries. Where there is no specific
regulation (e.g. Mexico), paramotor flying is tolerated provided the pilots
cooperate with local officials when appropriate.[citation needed] In countries
where specific regulation exists, such as Canada, France, Italy, and South
Africa, pilots must be trained, both in flying theory and practice, by licensed
instructors. Some countries that require formal certification frequently do so
through non-government ultralight aviation organizations.
Regardless of regulations, powered
paragliding can be dangerous when practiced without proper training.

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。
The most difficult aspect of paramotoring
is controlling the wing (paraglider) on the ground. This control is both during
launch and upon landing. Initial training in becoming a paramotor pilot
involves managing the wing in the air from the ground without the motor. This
process is called kiting and is the most complicated and important step in the
process. Once kiting the wing on the ground is mastered then the motor is added
to the process to practice with the weight of the paramotor included. A typical
paramotor will weigh on average around 50 lbs. (23 kg) with some models as
light at 40 lbs. (18 kg) and some models as high as 75 lbs. (34 kg.) The size
of the paramotor wing and engine are dependent on the weight of the pilot.
In many countries, including the United
States, powered paragliding is minimally regulated and requires no licence. The
ability to fly both low and slow safely, the 'open' feel, the minimal equipment
and maintenance costs, and the portability are claimed to be this type of
flying's greatest merits.[1]
Powered paragliders usually fly between 15
to 50 mph (24 to 80 km/h) at altitudes from 'foot-dragging on the water' up
about to 18,000 ft (5,500 m) or more with certain permission although most
flying is done under 500 ft (150 m) AGL.[2] Due to the paramotor's slow forward
speed and nature of a soft wing, it is not safe in high winds, turbulence, or
intense thermal activity.

阿拉善越野动力伞
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。
