Paramotor (动力伞) 源自英文
Paragliding(滑翔伞)和motor(摩托)。顾名思义,动力伞是在滑翔伞上加配了动力装置。1978年,法国登山家贝登先生成明了滑翔伞,使人类翱翔蓝天的梦想得以实现。然而,人们在欢喜之余发现,滑翔伞的飞翔与梦想中的自由飞翔仍有距离,**主要的一点就是不能在平地自由起降,起飞受山坡条件的制约,更使没有山峰地区的飞行爱好者感到难受。1984年,一群充满浪漫与幻想的法国滑翔伞爱好者,给滑翔伞加挂了一个小型发动机,利用发动机带动螺旋桨的推力和滑翔伞伞翼的升力,使平地“自由起降”不再成为问题,达到了自己飞得更高、更远,留空时间更长的目的,从而创立了这项新兴的航空体育项目。 天津越野动力伞使用方法
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.

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.
The paramotor, weighing from 45 to 90 lb
(20 to 41 kg) is supported by the pilot during takeoff. After a brief run
(typically 10 ft (3.0 m)) the wing lifts the motor and its harnessed pilot off
the ground. After takeoff, the pilot gets into the seat and sits suspended
beneath the inflated paraglider wing like a pendulum. Control is available
using brake toggles for roll and a hand-held throttle for pitch.
Military
Powered paragliding has seen a large growth
in the military including insertion of special forces soldiers and also Border
Patrol in many governments. The Lebanese Airborne regiment adopted this
technique in 2008, and the US Army, and Egyptian Army have used Paramotor Inc
FX Series units for many years.
规章制度
在大多数国家/地区中,动力伞驾驶员均遵循简单的规则进行操作,从而免除了飞行员和装备的认证要求。但是,这些法律限制了其飞行的范围-说明飞行员要避开拥挤的区域和较大的机场,以很大程度地降低对他人或飞机的风险。美国飞行员根据联邦航空管理局法规第103部分进行操作。
社团协会
在美国,这项运动主要由美国动力滑翔伞协会(USPPA)**[注1],该协会也享有一项豁免,允许由经过适当认证的双人教练进行两次训练。美国超轻型飞机协会(USUA)和航空运动连接公司(ASC)也提供了一些支持。
美国的讲师主要由美国动力滑翔伞协会(USPPA)**和认证。其他组织包括动力滑翔伞教练专业协会(***PI)。
在英国,这项运动由英国滑翔伞和滑翔伞协会**,而非正式地由Paramotor俱乐部**。[6]

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.
