滑翔傘在“大耳朵”機動

在不加速的情況下,正常飛行會拉動外部A線,使翼尖向內(nèi)折疊,這將大大減小滑行角,而前進速度*會小幅下降。隨著有效機翼面積的減小,機翼載荷增加,并且變得更加穩(wěn)定。但是,迎角增加了,飛行器更接近失速速度,但是可以通過應用速度桿來改善,這也增加了下降速度。釋放管路時,機翼會重新膨脹。如有必要,在制動器上短暫抽氣有助于重新進入正常飛行。與其他技術相比,機翼大了,機翼仍然向前滑動,這使飛行員可以離開危險區(qū)域。例如,如果飛行員必須抵抗斜坡上的上升氣流,這種方式甚至可以降落。


B線失速

在B線停轉(zhuǎn)中,從前緣/前端起的第二組立管(B線)**于其他立管被下拉,其中特定的線用于啟動停轉(zhuǎn)。這在翼上產(chǎn)生翼展方向的折痕,從而使氣流與翼的上表面分離。它顯著降低了頂篷產(chǎn)生的升力,從而導致更高的下降率。這可能是費力的動作,因為必須將這些B線保持在該位置,并且機翼的張力會在這些線上施加向上的力。必須小心處理這些線的釋放,以免引起機翼向前飛快射擊,然后飛行員可能掉入其中。現(xiàn)在這已經(jīng)不那么流行了,因為它在機翼的內(nèi)部結(jié)構(gòu)上引起了高負荷。

In 1952 Canadian Domina Jalbert patented a

governable gliding parachute with multi-cells and controls for lateral

glide.[2]


In 1954, Walter Neumark predicted (in an

article in Flight magazine) a time when a glider pilot would be "able to

launch himself by running over the edge of a cliff or down a slope ... whether

on a rock-climbing holiday in Skye or ski-ing in the Alps."[3]



In 1961, the French engineer Pierre

Lemongine produced improved parachute designs that led to the Para-Commander.

The PC had cutouts at the rear and sides that enabled it to be towed into the

air and steered, leading to parasailing/parascending.


Domina Jalbert invented the Parafoil, which

had sectioned cells in an aerofoil shape; an open leading edge and a closed

trailing edge, inflated by passage through the air – the ram-air design. He

filed US Patent 3131894 on January 10, 1963.[4]



The glide ratio of paragliders ranges from

9.3 for recreational wings to about 11.3 for modern competition models,[16]

reaching in some cases up to 13.[17] For comparison, a typical skydiving

parachute will achieve about 3:1 glide. A hang glider ranges from 9.5 for

recreational wings to about 16.5 for modern competition models. An idling

(gliding) Cessna 152 light aircraft will achieve 9:1. Some sailplanes can

achieve a glide ratio of up to 72:1.


The speed range of paragliders is typically

20–75 kilometres per hour (12–47 mph), from stall speed to maximum speed.

Beginner wings will be in the lower part of this range, high-performance wings

in the upper part of the range.[note 2]


For storage and carrying, the wing is

usually folded into a stuffsack (bag), which can then be stowed in a large

backpack along with the harness. For pilots who may not want the added weight

or fuss of a backpack, some modern harnesses include the ability to turn the

harness inside out such that it becomes a backpack.


無動力滑翔傘是借助傘翼在空中相對空氣的運動產(chǎn)生的升力,由飛行員通過操縱繩控制速度、方向等,實現(xiàn)無動力滑翔傘自由翱翔的。它起源于法國,于上世紀八十年代傳入中國,截至目前,國內(nèi)的持證滑翔傘飛行員剛剛過萬人,是極富魅力與想象力并且很厲害的潮人運動。

      請記住,滑翔傘不是降落傘,降落傘是“可展式氣動阻力器”,它能讓人或物體從空中以較小的勻速下降。而滑翔傘是人類目前創(chuàng)造出的簡易的飛行器,它能借助對流層中的熱氣流越飛越高,直到云底或者熱氣流消散的積云頂端。 崇明區(qū)正規(guī)滑翔傘廠家報價

The next step in the launch is to bring the

wing into the lift zone. There are two techniques for accomplishing this

depending on wind conditions. In light wind this is usually done after turning

to the front, steering with the feet towards the low wing tip, and applying

light brakes in a natural sense to keep the wing horizontal. In stronger wind

conditions it is often found to be easier to remain facing downwind while

moving slowly and steadily backwards into the wind.


Knees bent to load the wing, foot

adjustments to remain central and minimum use of Cs or Brakes to keep the wing

horizontal. Pirouette when the feet are close to lifting. This option has two

distinct advantages. a) The pilot can see the wing centre marker (an aid to

centring the feet) and, if necessary, b) the pilot can move briskly towards the

wing to assist with an emergency deflation.


With either method it is essential to check

"traffic" across the launch face before committing to flight.
