动力滑翔伞(“ PPG”)的线束和推进部分的总称。动力伞有两种基本类型:脚踏发动和车轮发动。


脚踏模型由带线束,油箱,发动机和螺旋桨的框架组成。带有防护网的铁环主要是将管线保持在螺旋桨之外。该装置就像一个大背包一样穿着,滑翔伞通过安全扣固定在大背包上。


车轮发射装置既可以作为带有自己的电动机的完整装置来提供,也可以作为脚踏发射动力装置的附加装置来提供。他们通常有3个(三轮车)或4个(四轮)车轮,可容纳一两个乘客。这些不应与动力降落伞相混淆,动力降落伞通常重得多,功率更大并且具有不同的操纵方向。


这个词**初是由英国人麦克·拜恩(Mike Byrne)在1980年使用的[1],并在1986年左右的法国流行起来,当时拉穆埃(La Mouette)开始为当时的新滑翔伞机翼调整动力。

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.

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]



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.





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.

在开始培训时,您将开始意识到这项运动涉及多少,它不是空中摩托车或水上摩托车,因此了解飞***象学至关重要。


滑翔伞(也称为动力滑翔伞)将滑翔伞的易飞特性与动力飞行的自主性和范围结合在一起。


动力伞(由Paul Bailey提供)

动力伞相对易于学习飞行,并且可以脚踩启动,只要有您的许可,并且只要没有树,牲畜或旁观者的危害,它们都可以在空旷的平坦场地起飞。

(飞机场当然是理想的)无需找到面向风的小山地,甚至无需等待风吹来。


它们可以快速,轻松地进行索具和索具的拆卸,一旦拆除,就可以放在汽车的后备箱中,也可以作为手提行李带到异国的地点。


动力伞到底是什么?


这是所有动力飞机中**简单的飞机,由驱动螺旋桨的小型电动机组成,螺旋桨像背包一样穿着在滑翔伞机翼下方,并提供起飞,爬升和保持水平飞行的推力。


一旦升空后,滑翔伞就可用于沿着下方行驶并观察周围的世界,或者在条件允许的情况下,以热升力飙升以进行长时间的越野飞行。


电动机可以在空中停止和重新启动,其中许多电动机具有电启动器,使飞行员能够使其飞行适应当前条件。

我们在使用这类生物菌之前,必须要先将其放在水分充足的环境中静置30~60分钟。不管是喷施用的还是土埋用的,使用之前都必须经过这样的处理。其次,***后的孢子,其寿命只有一个月左右的时间。有果农说,它不是可以繁殖的吗?非也,只有未经过改良的活菌才能繁殖,而经过改造的孢子是不具备这个功能的,哪怕是孵化之后的孢子也没有。也就是说,我们用这种生物菌的时候,本来有多少孢子,用到田里时多也就只有这么多活菌,往后活菌只会越来越少,不会增多。那么包装袋上显示的是“XX亿活菌”字样的生物菌呢?毋庸置疑,它是完全具备增殖能力的。这么说来,岂不是我们把这类生物菌施下去以后,它就可以持续繁殖下去发挥作用了?小心别被厂...
