成都油耗动力伞怎么买

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，动力伞.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.

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.

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.

2005年10月，中国航协向国际航联递交了申请承办2007年第五届世界动力伞锦标赛的报告，得到与会**的极大认同，大会一致同意由中国承办2007年第五届世界动力伞锦标赛，各国运动员都在期待着到中国的飞行、在万里长城上空的翱翔。

  除了休闲娱乐和参加竞技比赛外 目前，动力伞运动，还从事着许多特殊的行业，比如：广告飞行，航空拍摄，警用空中巡逻，训练，森林防火，架设电缆，航空表演等，人们驾驶着动力伞，在空中翱翔，享受着鸟儿般的自由与刺激。利用动力伞进行的各项事业也越来越受到社会的欢迎和选择。随着我国经济的发展和人民生活水平的不断提高，将会有更多喜爱飞行的人们加入到这项运动中来。

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.
