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.

中国航空运动协会(简称中国航协)是国际航联的会员组织,是我国**性的体育组织,从民间的角度授权管理、组织、开展我国的航空运动。中国航协下设航空模型、跳伞、飞行、悬挂滑翔和热气球等项目委员会。悬挂滑翔委员会主管滑翔伞和动力伞运动。
我国开展动力伞运动始于20世纪90年代。1991年10月,法国动力伞**团到广西桂林旅游飞行带来了动力伞,这是我国正式接触动力伞飞行。 黄山框架动力伞多少钱
1994年国内开始引进动力伞器材,同年,中国航协举办了首届动力伞训练班,**早参加动力伞运动的主要是我国飞机跳伞和滑翔伞运动员,有北京、四川、湖北、河南、广东共11人参加了这次理论和技术培训,为中国的动力伞运动培养了首批骨干。
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.
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]
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.

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.

防治白蚁对杀虫剂种类和剂型选择:白蚁防治公司应从危害的白蚁种类以及药物的价格、效果方面行选择。拟除虫菊醋类杀虫剂的毒性较低,比有机磷类杀虫剂更安全,且没有有机磷类杀虫剂所特有的气味,更适合用于室内环境;氟虫腈、咪蚜胺对防治白蚁具有较好的效果;氟铃脲为昆虫生长调节剂,安全性高、专一性强,更为环保。上述任意一类型杀虫剂均具有杀灭白蚁的作用,因此选择合适的剂型更为重要。、城市建筑物白蚁的防治:不同种类的白蚁危害特点不同,选择杀虫剂的剂型也不同。(1)家白蚁的防治。可选用粉剂毒杀,饵剂诱杀。(2)散白蚁的防治。可选用可湿性粉剂和乳油喷洒,粉剂毒杀,饵剂诱杀。(3)堆砂白蚁的防治。可选用熏蒸剂和片剂熏蒸...
