Federation Aeronautique Internationale国际航空运动联合会(FAI)(以下简称国际航联)是国际航空运动的国际组织,总部设在瑞士洛桑。1975年,国际航联在其第68届大会上决定设立悬挂滑翔委员会,动力伞和滑翔伞运动同属悬挂滑翔委员会的管理。
1999年在??举办了**届世界动力伞锦标赛,2001年在??举办了第二届世界动力伞锦标赛,2003年在??举行了第三届世界动力伞锦标赛,2005年8月18日至23日,在法国举行了第四届世界动力伞锦标赛。 还有世界航空运动会 欧洲锦标赛 2007年 月 日 至 日,在中国北京举行了第五届世界动力伞锦标赛 博尔塔拉油耗动力伞怎么买
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.

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.
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.
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).

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。 博尔塔拉油耗动力伞怎么买
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。上海翼舞航空科技有限公司致力于运动、休闲,是一家生产型公司。公司自成立以来,以质量为发展,让匠心弥散在每个细节,公司旗下动力伞,滑翔伞,飞行,热汽球深受客户的喜爱。公司将不断增强企业重点竞争力,努力学习行业知识,遵守行业规范,植根于运动、休闲行业的发展。翼舞立足于全国市场,依托强大的研发实力,融合前沿的技术理念,飞快响应客户的变化需求。
痕灌技术的关键节水部件是痕灌控水头,由具有良好导水性能的毛细管束和具有过滤功能的痕灌膜组成,控水头埋在作物根系附近,毛细管束一端与充满水的管道相连,另一端与土壤的毛细管相连,感知土壤水势的变化。作物吸水导致根系周围的水势降低,即发出需水信号,控水头内的水不断以毛细管水的形式流向根系周围,直至作物停止吸水;控水头内的痕灌膜可防止毛细管束因杂质而堵塞,保证系统长期稳定工作。多年田间试验表明,痕灌比滴灌节水50%左右,即使在滴灌无法使用的地区也可推广应用。痕量灌溉应用前景广阔。痕灌节水技术能耗更少,节水更多。尤其是能够突破在常规节水灌溉很少涉及的荒漠化治理、矿山修复、城市绿化等领域的发展,能为解决粮...
