Regulations
In most countries, paramotor pilots operate
under simple rules that spare them certification requirements for pilot and
gear. Those laws, however, limit where they can fly—specifying that pilots
avoid congested areas and larger airports to minimize risk to other people or
aircraft. U.S. pilots operate under Federal Aviation Administration regulation
Part 103.
Associations
In the U.S., the sport is represented
primarily by the US Powered Paragliding Association (USPPA)[note 1] which also
holds an exemption allowing two-place training by appropriately certified
tandem instructors. The US Ultralight Association (USUA) and Aero Sports
Connections (ASC) also offer some support.
Instructors in the U.S. are primarily
represented and certified by the United States Powered Paragliding
Association(USPPA). Other organizations include the Professional Association of
Powered Paragliding Instructors (***PI).

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.

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.
在包括美国在内的许多国家/地区,对动力滑翔伞的管制很少,不需要执照。这种飞行的比较大优点是能够安全低空飞行和缓慢飞行,“开放”的感觉,**少的设备和维护成本以及便携性。[1]
动力滑翔伞通常在15到50英里/小时(24到80公里/小时)的飞行速度下,从“在水上拖曳脚踏”到大约18,000英尺(5,500 m)或更高的高度,尽管大多数飞行是在500英尺以下完成的(150 m)AGL。[2]由于动力伞的慢速前进速度和柔和的机翼特性,在大风,湍流或激烈的热活动中它并不安全。
起飞期间,飞行员会支撑重达45至90磅(20至41千克)的动力伞。短暂运行(通常为10英尺(3.0 m))后,机翼将电动机及其吊带飞行员抬离地面。起飞后,飞行员进入座位并像钟摆一样悬挂在充气的滑翔伞机翼下方。可使用制动拨动(用于横滚)和手持节气门(用于俯仰)进行控制。
动力滑翔伞在**中得到了巨大的发展,包括在许多**中部署了特种**士兵以及边境巡逻队。黎巴嫩空降团于2008年采用了这种技术,美国陆军和埃及陆军已经使用了Paramotor Inc FX系列装置多年。
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.

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.

所以它同时还提到了踢脚线的作用。也就是说,我们家的这些位置由于踢脚暖的存在而就避免了被磕碰的现象。可以说是一举两得。二、散热方式1.由于供热产生的热空气比室内原来的冷空气密度要低,所以热空气在通过热传导散发出来以后,是向上升的。而且它会沿着我们室内几乎所有的墙面均匀地顺着墙壁的位置上升。2.踢脚暖的这个散热的特点也就决定了可以实现室内温度均匀的上升。使得室内整体的温度是趋于一致的。这一点与传统的暖气片相比有明显的优势。传统暖气片是暖气片附近呀比较暖和,而其它地方温度是相对要低一些的。三、安装空间1.踢脚暖的尺寸,一般来说高度是300mm,或者是400mm,当然要根据我们的要求去进行...
