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.

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.

学习驾驶动力伞
在使用动力进行***飞行之前,您首先需要学习如何飞行机翼。
一旦掌握了这一点,您的讲师将转向动力单元,您将学习如何组装和拆卸动力单元(这是为了轻松运输,而不是进行大修整!),启动动力伞,控制油门并进行基本的日常维护。您的讲师还将解释扭矩和推力影响,并讨论安全问题。
然后将这两个要素放在一起,教您使用动力飞行。滑翔伞需要与飞行理论和气象知识相同的知识,并且由于使用引擎可以随意漫游,因此相当重视学习空中航行和导航。

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.
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.
