Reverse launches have a number of

advantages over a forward launch. It is more straightforward to inspect the

wing and check if the lines are free as it leaves the ground. In the presence

of wind, the pilot can be tugged toward the wing, and facing the wing makes it

easier to resist this force and safer in case the pilot slips (as opposed to

being dragged backwards). However, the movement pattern is more complex than

forward launch, and the pilot has to hold the brakes in a correct way and turn

to the correct side so he does not tangle the lines. These launches are

normally attempted with a reasonable wind speed, making the ground speed

required to pressurise the wing much lower.


The launch is initiated by the hands

raising the leading edge with the As. As it rises the wing is controlled more

by centring the feet than by use of the brakes or Cs. With mid level wings (EN

C and D) the wing may try to "overshoot" the pilot as it nears the

top. This is checked with Cs or brakes. The wing becomes increasingly sensitive

to the Cs and brakes as its internal air pressure rises.

Forward launch

In low winds, the wing is inflated with a

forward launch, where the pilot runs forward with the wing behind so that the

air pressure generated by the forward movement inflates the wing.


It is often easier, because the pilot only

has to run forward, but the pilot cannot see his wing until it is above him,

where he has to check it in a very short time for correct inflation and

untangled lines before the launch.


Reverse launch

In higher winds, a reverse launch is used,

with the pilot facing the wing to bring it up into a flying position, then

turning around under the wing and running to complete the launch.

Paragliding is the recreational and competitive adventure sport of flying paragliders: lightweight, free-flying,

foot-launched glider aircraft with no rigid primary structure.[1] The pilot sits in a harness suspended below a fabric wing. Wing shape is maintained by the suspension lines, the pressure of air entering vents in the front of the wing, and the aerodynamic forces of the air flowing over the outside.

 Despite not using an engine, paragliderflights can last many hours and cover many hundreds of kilometres, though flights of one to two hours and covering some tens of kilometres are more the norm. By skillful exploitation of sources of lift, the pilot may gain height,

often climbing to altitudes of a few thousand metres.




熱飛行


托里·派恩斯滑翔傘在空中滑翔傘

當(dāng)太陽(yáng)溫暖地面時(shí),它將使某些功能比其他功能(例如巖石表面或大型建筑物)加熱得更多,而這些功能會(huì)引發(fā)通過(guò)空氣上升的熱量。有時(shí),這些可能只是空氣的簡(jiǎn)單上升;通常,它們?cè)陲L(fēng)中向側(cè)面吹,會(huì)從源頭脫落,隨后形成新的熱量。


一旦飛行員找到了熱量,他便開(kāi)始繞圈飛行,試圖將圓圈定位在熱量**強(qiáng)的部分(“**”)上,其中空氣的上升**快。大多數(shù)飛行員使用可變高度計(jì)(“ vario”),通過(guò)嘟嘟聲和/或視覺(jué)顯示來(lái)指示爬升率,以幫助將熱量插入磁芯中。


通常情況下,周圍的熱源周圍有很強(qiáng)的水槽,當(dāng)飛行員試圖進(jìn)入強(qiáng)熱源時(shí),也存在強(qiáng)烈的湍流,導(dǎo)致機(jī)翼塌陷。良好的熱力飛行是一項(xiàng)需要花費(fèi)時(shí)間學(xué)習(xí)的技能,但是好的飛行員通??梢詫崃σ恢必灤┑秸麄€(gè)云層。

一旦掌握了使用熱量來(lái)獲得高度的技巧,飛行員就可以從一個(gè)熱量滑到另一個(gè)熱量來(lái)穿越國(guó)家。在熱量中獲得高度后,飛行員會(huì)下滑到下一個(gè)可用熱量。

Europe has seen the greatest growth in

paragliding, with France alone registering in 2011 over 25,000 active pilots.

The paraglider wing or canopy is usually

what is known in engineering as a "ram-air airfoil". Such wings

comprise two layers of fabric that are connected to internal supporting

material in such a way as to form a row of cells. By leaving most of the cells

open only at the leading edge, incoming air keeps the wing inflated, thus

maintaining its shape. When inflated, the wing's cross-section has the typical

teardrop aerofoil shape. Modern paraglider wings are made of high-performance

non-porous materials such as ripstop polyester[12] or nylon fabric.[note 1]

飛行中的機(jī)翼放氣(崩潰)

由于機(jī)翼(機(jī)翼)的形狀是由進(jìn)入機(jī)翼并使之膨脹的運(yùn)動(dòng)空氣形成的,因此在湍流的空氣中,機(jī)翼的一部分或全部會(huì)收縮(塌陷)。被稱為“主動(dòng)飛行”的飛行員技術(shù)將**降低通氣或坍塌的頻率和嚴(yán)重性。這種通縮通常無(wú)需飛行員干預(yù)即可恢復(fù)。如果發(fā)生嚴(yán)重的放氣,正確的飛行員輸入將加快從放氣中恢復(fù)的速度,但是錯(cuò)誤的飛行員輸入會(huì)減慢滑翔機(jī)返回正常飛行的速度,因此飛行員必須進(jìn)行正確的訓(xùn)練和練習(xí)以應(yīng)對(duì)放氣。


在極少數(shù)情況下,無(wú)法從通縮中恢復(fù)(或從諸如旋轉(zhuǎn)等其他威脅性狀況中)恢復(fù)過(guò)來(lái)的情況下,大多數(shù)飛行員會(huì)攜帶備用(救援,緊急情況)降落傘。但是,大多數(shù)飛行員從來(lái)沒(méi)有理由“扔”他們的儲(chǔ)備。如果機(jī)翼在低空發(fā)生放氣,即在起飛后不久或著陸前不久,機(jī)翼(滑翔傘)可能無(wú)法迅速恢復(fù)其正確的結(jié)構(gòu)以防止發(fā)生,飛行員通常沒(méi)有足夠的剩余高度來(lái)部署后備力量降落傘[**小降落高度大約為60 m(200 ft),但通常在穩(wěn)定期使用120-180 m(390-590 ft)的高度進(jìn)行典型部署]。備用降落傘的不同包裝方式會(huì)影響其部署時(shí)間。
