動(dòng)力滑翔傘三輪車(chē)著陸
輕便的手推車(chē)或“三輪車(chē)”(如果有四個(gè)輪子,則稱(chēng)為“四輪摩托車(chē)”)也可以安裝在動(dòng)力滑翔傘上,以供那些不愿或無(wú)法用腳踩發(fā)射的人使用。有些是常設(shè)單位。
在美國(guó),如果飛機(jī)符合超輕定義,則無(wú)需許可證。在英國(guó),如果“飛機(jī)的性能仍然與可以腳踩的飛機(jī)相同”,則安裝在三輪車(chē)上的動(dòng)力傘仍被歸類(lèi)為“自行式滑翔機(jī)”。 [7]。但是,即使在這些國(guó)家/地區(qū),如果機(jī)器有兩個(gè)座位,也不再是一件輕巧的事。在美國(guó),這種飛行器將受《運(yùn)動(dòng)飛行員》規(guī)則的管轄,并被監(jiān)管為輕型運(yùn)動(dòng)飛機(jī)動(dòng)力降落傘,這需要飛機(jī)的N號(hào),并且飛行員必須獲得許可。
動(dòng)力滑翔傘與動(dòng)力降落傘(PPC)的主要區(qū)別在于尺寸,功率,控制方法和乘員人數(shù)。動(dòng)力滑翔傘體積更小,使用效率更高(但更難管理)的滑翔傘機(jī)翼,并像運(yùn)動(dòng)飛將軍一樣使用剎車(chē)肘桿進(jìn)行轉(zhuǎn)向。動(dòng)力降落傘通常使用易于管理但效率較低的機(jī)翼,具有更大的發(fā)動(dòng)機(jī),用腳掌操縱,并可能隨身攜帶乘客。有例外;越來(lái)越多的動(dòng)力降落傘使用橢圓機(jī)翼,一些使用手動(dòng)控制裝置,許多是符合FAA第103部分要求的輕型單座飛機(jī)。

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.

動(dòng)力傘飛行是一項(xiàng)集技能、體能、智能于一體的時(shí)尚體育運(yùn)動(dòng),同時(shí)也是一項(xiàng)勇敢者的運(yùn)動(dòng)。動(dòng)力傘飛行所使用的器材是至今為止,人類(lèi)可控飛行**容易掌握的有動(dòng)力載人**小飛行器。動(dòng)力傘作為一種飛行器,有續(xù)航時(shí)間長(zhǎng)、造價(jià)低、雷達(dá)反射面小、載荷大等特點(diǎn)。
動(dòng)力傘運(yùn)動(dòng)是運(yùn)動(dòng)員駕駛動(dòng)力傘飛行器材,在平地完成起飛升空,低空完成踢標(biāo)、繞標(biāo)、定點(diǎn),空中完成延時(shí)留空、目標(biāo)尋找、速度競(jìng)賽等飛行科目的航空運(yùn)動(dòng)項(xiàng)目。在許多競(jìng)速科目中,只規(guī)定了一些必須飛越的標(biāo)志點(diǎn),至于點(diǎn)與點(diǎn)之間的飛行順序、飛行方向、飛行路線,都需要運(yùn)動(dòng)員自己做出判斷,并在**短的時(shí)間內(nèi)做出決策和完成任務(wù)。在規(guī)定方向和順序的踢標(biāo)、繞標(biāo)科目中,運(yùn)動(dòng)員要人與器材密切配合,既要熟練掌握動(dòng)力傘的操縱技法又要體會(huì)和判斷氣候的影響、風(fēng)的變化,做到人傘合一。動(dòng)力傘運(yùn)動(dòng)不僅是一項(xiàng)身體和技能的訓(xùn)練,更是一項(xiàng)心智的訓(xùn)練。這項(xiàng)運(yùn)動(dòng)涉及到航空理論、氣象知識(shí)、運(yùn)動(dòng)健身等多學(xué)科知識(shí)。深受廣大航空運(yùn)動(dòng)愛(ài)好者的喜愛(ài)。
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.
A powered paraglider trike landing
Lightweight carts or "trikes"
(called "quads" if they have four wheels) can also be mounted on powered
paragliders for those who prefer not to, or are unable to, foot launch. Some
are permanent units.
In the United States, if the aircraft meets
the ultralight definitions, no license is required. In the UK, trike-mounted
paramotors are still classified as 'self-propelled hang-gliders' if the
"performance of the aircraft remains equivalent to one that can be
foot-launched." [7]. However, even in these countries, if the machine has
two seats it is no longer an ultralight. In the US such a craft would be governed
under the Sport Pilot rules and regulated as a light sport aircraft powered
parachute which requires an aircraft N-number and pilots must be licensed.

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.
