喀什座袋动力伞安全系数

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，动力伞.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.

中国航协悬挂滑翔委员会在社会赞助和支持下，先后在北京、上海、天津、广州、深圳、武汉、成都、西安、青岛、大连、哈尔滨、沈阳、石家庄、郑州、南昌、南京、杭州、福州、厦门等城市组织了多次动力伞巡回赛、动力伞邀请赛和全国锦标赛并组织了多次动力伞飞行表演，每次的赛事和活动都在社会上产生了巨大影响，从而推动了我国动力伞运动的发展。1997年，中国香港回归之际，成功举办了中国香港至北京动力伞拉力赛，2004年，“海尔杯”动力伞巡回赛，历经三个多月十八个城市，到场观众超过了20万人，中央电视台国际频道对赛事进行了全程报道并制作了多集专题片。2005年，在上海成功举办了有七个国家和地区45名运动员参加的国际动力伞邀请赛，特别邀请了国际航联的官员和裁判，得到了国际专家们的充分肯定。中国航协也组织参加了多次在国外举行的世界性比赛， 2005年8月，中国动力伞**队3名运动员，参加了在法国举办的世界动力伞锦标赛。2006年，再次得到国际知名企业的赞助和支持，成功在五个城市举行了“丰田锐志杯”动力伞巡回赛暨全国锦标赛。由于国内举办各种动力伞赛事和活动的巨大成功，得到了国际航联的高度重视。

噪声

相对于观察者的动力伞噪声取决于动力装置的距离，响度，频率和音质。大部分噪音来自螺旋桨，而缓慢的转速被认为是**安静的。飞行员可以通过将噪声敏感的区域保持在低功率状态来减轻其声音影响，将实际距离保持在**远的位置，并减少在该区域附近所花费的时间。

执照和培训

在美国，英国或许多其他国家，既不需要许可证，也不需要特定的培训。在没有特别规定的地方（例如墨西哥），只要飞行员在适当的情况下与当地官员合作，就可以容许滑翔伞飞行。[需要引用]在存在特别规定的国家（例如加拿**国，意大利和南非），飞行员必须由执照的教练进行飞行理论和实践方面的培训。一些需要正式认证的国家经常通过非**的超轻航空组织进行认证。

无论法规如何，如果没有经过适当培训，进行动力滑翔伞运动都是很危险的。

对于飞行员来说，要通过大多数组织的完整飞行员教学大纲，需要5到15天的时间，由于天气原因，这可能需要更长的日历时间。教学中使用了许多技巧，尽管大多数技巧包括让学生熟悉在地面上，通过牵引，小山丘或串列飞行时如何操纵机翼。

借助特殊装备，可以乘搭乘客（双人），但是大多数国家（包括美国）都需要某种形式的证明。

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).

This sport has evolved and now many

advanced pilots perform extreme maneuvers such as wing-overs, barrel rolls and

loops. These types of maneuvers present a significant danger as any type of

negative G's encountered will unload the wing allowing the wings lines to go

slack. Only very advanced pilots with years of experience, training and coupled

with countermeasures such as reserve parachutes should attempt such maneuvers.

A reserve parachute is a highly recommended piece of equipment which may

prevent significant injury or death in the presence of a malfunction of the

equipment or a mistake made by the pilot.

Powered paragliding, also known as

paramotoring or PPG, is a form of ultralight aviation where the pilot wears a

back-mounted motor (a paramotor) which provides enough thrust to take off using

a paraglider. It can be launched in still air, and on level ground, by the

pilot alone — no assistance is required.
