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.

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.

动力滑翔伞可用作在困难地形中的陆地车辆的替代品。在春季某些地区,当海洋或湖泊仍然结冰,但冰已经开始融化时,水将无法行走,滑行或行驶,也无法乘船航行。在这种情况下,水上直升机,气垫船旅行方式。此外,如果像沼泽地一样,地形被小而浅的湖泊和海湾所破坏,即使在良好的条件下也可能难以导航。观察和计数受保护物种,例如在这种情况下,Saimaa环型密封已经使用动力滑翔伞进行了。
已证明的另一种用途是驯鹿放牧。尽管冻原是开阔的地形,但没有道路,地形仍然不平坦。可以使用动力降落伞代替雪地摩托或摩托车。

研究估计,这项活动(每项活动)比骑摩托车稍微安全一些,并且比坐汽车更危险。[3]严重伤害的**可能原因是身体与旋转的螺旋桨接触。下一个**可能造成伤害的原因是飞入降落区以外的地方。[4]一些飞行员携带备用降落伞,设计用于在15英尺(50英尺)的范围内打开。
这些飞机缺乏既定的设计标准,导致英国查处在2007年得出结论:“只有在确定了实际吊运质量的单个线束/机翼组合的精确储备系数时,才采用适合于机动的负荷系数。进行,这些飞机是否可以被认为在结构上安全” [5]
For a pilot to get through most
organizations' full pilot syllabus requires between 5 and 15 days which, due to
weather, may include far more calendar time. A number of techniques are
employed for teaching, although most include getting the student familiar with
handling the wing either on the ground, via towing, small hills, or on tandem
flights.
With special gear it is possible to take a
passenger (tandem), but most countries, including the U.S., require some form
of certification to do so.
The pilot controls thrust via a hand-held
throttle and steers using the wings brake toggles or stabilo steering, weight
shifting or a combination of the three. It is identical to Paragliding except
it is powered so the use of an elevation or thermals to ascend are not
required. Paramotor wings have evolved specifically for use with power
propulsion, as compared with free flight 'paraglider' wings. Such wings are
typically designed for a higher speed and may incorporate a "reflex"
profile to aid stability in pitch, an idea taken from hang gliders of the
1980s. Paramotor wings typically use trimmers to adjust the Angle of Attack of
the wing to either slow it down or speed it up in flight. Trimmed out allows
the pilot to achieve maximum speed, while trimmed in allows for slower speeds
optimized for launching and landing.

Paramotor (动力伞) 源自英文
Paragliding(滑翔伞)和motor(摩托)。顾名思义,动力伞是在滑翔伞上加配了动力装置。1978年,法国登山家贝登先生成明了滑翔伞,使人类翱翔蓝天的梦想得以实现。然而,人们在欢喜之余发现,滑翔伞的飞翔与梦想中的自由飞翔仍有距离,**主要的一点就是不能在平地自由起降,起飞受山坡条件的制约,更使没有山峰地区的飞行爱好者感到难受。1984年,一群充满浪漫与幻想的法国滑翔伞爱好者,给滑翔伞加挂了一个小型发动机,利用发动机带动螺旋桨的推力和滑翔伞伞翼的升力,使平地“自由起降”不再成为问题,达到了自己飞得更高、更远,留空时间更长的目的,从而创立了这项新兴的航空体育项目。 上海学习动力伞
