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。

安全法规

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]

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).

A powered paraglider trike landing

Lightweight carts or "trikes"

(called "quads" if they have four wheels) can also be mounted on powered

paragliders for those who prefer not to, or are unable to, foot launch. Some

are permanent units.

In the United States, if the aircraft meets

the ultralight definitions, no license is required. In the UK, trike-mounted

paramotors are still classified as 'self-propelled hang-gliders' if the

"performance of the aircraft remains equivalent to one that can be

foot-launched." [7]. However, even in these countries, if the machine has

two seats it is no longer an ultralight. In the US such a craft would be governed

under the Sport Pilot rules and regulated as a light sport aircraft powered

parachute which requires an aircraft N-number and pilots must be licensed.

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.

Powered paragliders are useful as

replacements for terrestrial vehicles in difficult terrain. In some areas

during the spring when the sea or lakes are still frozen but the ice has begun

melting, the waters cannot be walked, skied, or driven on and cannot be

navigated by boat. Hydrocopters, hovercraft, and aircraft are the only ways to

travel in such conditions. Furthermore, if the landscape is fractured by small

and shallow lakes and bays, as in swamplands, it may be difficult to navigate

even in good conditions. Observation and counting of protected species, e.g.

Saimaa ringed seal, in such conditions has been conducted using a powered

paraglider.

Another use that has been demonstrated is

the herding of reindeer. Although the tundra is open terrain, there are no

roads and the terrain is still uneven. A powered parachute can be used instead

of a snowmobile or a motorcycle.
