Safety and regulations
Research estimates that the activity is
slightly safer (per event) than riding motorcycles and more dangerous than
riding in cars.[3] The most likely cause of serious injury is body contact with
a spinning propeller. The next most likely cause of injury is flying into
something other than the landing zone.[4] Some pilots carry a reserve parachute
designed to open in as little as 50 ft (15 m).
The lack of established design criteria for
these aircraft led the British Air Accidents Investigation Branch to conclude
in 2007 that "Only when precise reserve factors have been established for
individual harness/wing combinations carrying realistic suspended masses, at
load factors appropriate to the maneuvers to be carried out, can these aircraft
be considered to be structurally safe"[5]

在開(kāi)始培訓(xùn)時(shí),您將開(kāi)始意識(shí)到這項(xiàng)運(yùn)動(dòng)涉及多少,它不是空中摩托車或水上摩托車,因此了解飛***象學(xué)至關(guān)重要。
滑翔傘(也稱為動(dòng)力滑翔傘)將滑翔傘的易飛特性與動(dòng)力飛行的自主性和范圍結(jié)合在一起。
動(dòng)力傘(由Paul Bailey提供)
動(dòng)力傘相對(duì)易于學(xué)習(xí)飛行,并且可以腳踩啟動(dòng),只要有您的許可,并且只要沒(méi)有樹(shù),牲畜或旁觀者的危害,它們都可以在空曠的平坦場(chǎng)地起飛。
(飛機(jī)場(chǎng)當(dāng)然是理想的)無(wú)需找到面向風(fēng)的小山地,甚至無(wú)需等待風(fēng)吹來(lái)。
它們可以快速,輕松地進(jìn)行索具和索具的拆卸,一旦拆除,就可以放在汽車的后備箱中,也可以作為手提行李帶到異國(guó)的地點(diǎn)。
動(dòng)力傘到底是什么?
這是所有動(dòng)力飛機(jī)中**簡(jiǎn)單的飛機(jī),由驅(qū)動(dòng)螺旋槳的小型電動(dòng)機(jī)組成,螺旋槳像背包一樣穿著在滑翔傘機(jī)翼下方,并提供起飛,爬升和保持水平飛行的推力。
一旦升空后,滑翔傘就可用于沿著下方行駛并觀察周圍的世界,或者在條件允許的情況下,以熱升力飆升以進(jìn)行長(zhǎng)時(shí)間的越野飛行。
電動(dòng)機(jī)可以在空中停止和重新啟動(dòng),其中許多電動(dòng)機(jī)具有電啟動(dòng)器,使飛行員能夠使其飛行適應(yīng)當(dāng)前條件。

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.
動(dòng)力滑翔傘可用作在困難地形中的陸地車輛的替代品。在春季某些地區(qū),當(dāng)海洋或湖泊仍然結(jié)冰,但冰已經(jīng)開(kāi)始融化時(shí),水將無(wú)法行走,滑行或行駛,也無(wú)法乘船航行。在這種情況下,水上直升機(jī),氣墊船旅行方式。此外,如果像沼澤地一樣,地形被小而淺的湖泊和海灣所破壞,即使在良好的條件下也可能難以導(dǎo)航。觀察和計(jì)數(shù)受保護(hù)物種,例如在這種情況下,Saimaa環(huán)型密封已經(jīng)使用動(dòng)力滑翔傘進(jìn)行了。

安全法規(guī)
研究估計(jì),這項(xiàng)活動(dòng)(每項(xiàng)活動(dòng))比騎摩托車稍微安全一些,并且比坐汽車更危險(xiǎn)。[3]嚴(yán)重傷害的**可能原因是身體與旋轉(zhuǎn)的螺旋槳接觸。下一個(gè)**可能造成傷害的原因是飛入降落區(qū)以外的地方。[4]一些飛行員攜帶備用降落傘,設(shè)計(jì)用于在15英尺(50英尺)的范圍內(nèi)打開(kāi)。
這些飛機(jī)缺乏既定的設(shè)計(jì)標(biāo)準(zhǔn),導(dǎo)致英國(guó)查處在2007年得出結(jié)論:“只有在確定了實(shí)際吊運(yùn)質(zhì)量的單個(gè)線束/機(jī)翼組合的精確儲(chǔ)備系數(shù)時(shí),才采用適合于機(jī)動(dòng)的負(fù)荷系數(shù)。進(jìn)行,這些飛機(jī)是否可以被認(rèn)為在結(jié)構(gòu)上安全” [5]
飛行員通過(guò)手持節(jié)氣門控制推力,并使用機(jī)翼剎車肘節(jié)或stabilo轉(zhuǎn)向,重量轉(zhuǎn)移或這三者的組合進(jìn)行轉(zhuǎn)向。它與滑翔傘相同,只是它是動(dòng)力驅(qū)動(dòng)的,因此不需要使用海拔或熱量來(lái)提升。與自由飛行的“滑翔傘”機(jī)翼相比,動(dòng)力傘的機(jī)翼已經(jīng)專門為動(dòng)力推進(jìn)而發(fā)展。這樣的機(jī)翼通常被設(shè)計(jì)用于更高的速度,并且可以結(jié)合“反射”輪廓以有助于俯仰的穩(wěn)定性,該想法取自1980年代的懸掛式滑翔機(jī)。動(dòng)力傘的機(jī)翼通常使用微調(diào)器來(lái)調(diào)節(jié)機(jī)翼的迎角,以使其減速或加速飛行。修剪允許飛行員達(dá)到比較大速度,修剪允許允許針對(duì)發(fā)射和降落進(jìn)行優(yōu)化的較慢速度。
滑行**困難的方面是控制地面上的機(jī)翼(滑翔傘)。該控制既在發(fā)射期間又在著陸時(shí)進(jìn)行。成為滑翔傘飛行員的初步培訓(xùn)包括在沒(méi)有馬達(dá)的情況下管理地面上的機(jī)翼。此過(guò)程稱為工具包,是該過(guò)程中**復(fù)雜,**重要的步驟。一旦掌握了地面上的機(jī)翼套件,便將電動(dòng)機(jī)添加到該過(guò)程中,以便在練習(xí)中使用附帶動(dòng)力的重量。典型的動(dòng)力傘平均重約50磅。
(23公斤),某些型號(hào)的重量為40磅。
(18公斤),某些型號(hào)的重量高達(dá)75磅。
(34公斤)。動(dòng)力傘翼和發(fā)動(dòng)機(jī)的尺寸取決于飛行員的體重。

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.
