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.

Europe has seen the greatest growth in

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

3) rib

5) upper line cascade

6) middle line cascade

7) lower line cascade

8) risers

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]

青浦區(qū)**滑翔傘價(jià)格如何計(jì)算

在亞洲，日本、韓國、中國的中國臺(tái)灣省等經(jīng)濟(jì)發(fā)達(dá)國家和地區(qū)的滑翔傘運(yùn)動(dòng)十分普及，愛好者達(dá)十多萬人。20世紀(jì)80年代末，滑翔傘運(yùn)動(dòng)傳入中國大陸并迅速發(fā)展，

現(xiàn)注冊(cè)的航空俱樂部有50多個(gè)，正式會(huì)員1400多人，經(jīng)常從事滑翔傘飛行者達(dá)數(shù)千人，在中國東北、長(zhǎng)三角、珠三角長(zhǎng)期有民間高手飛行，隨著滑翔傘運(yùn)動(dòng)的逐漸普及，包括央視在內(nèi)的很多電視媒體都對(duì)這一運(yùn)動(dòng)進(jìn)行過專題報(bào)道。

滑翔傘通常主要由翼型傘衣、傘繩、背帶系統(tǒng)和操縱系統(tǒng)四大部分組成。為便于滑翔傘的保管、攜帶與運(yùn)輸，每具滑翔傘還配有一只背式包裝袋。

翼型傘衣，也稱傘翼，是滑翔傘產(chǎn)生升力和承受載荷的主要部件。傘衣的形狀、面積以及與氣流相對(duì)運(yùn)動(dòng)的速度，對(duì)升力的產(chǎn)生有很大的影響。

翼型傘衣由上翼面、下翼面和沿翼展方向有規(guī)律分布的數(shù)十個(gè)成形翼肋構(gòu)成。上下翼面與翼肋縫合，形成特定的傘翼形狀。傘衣前緣按照翼肋的橫向排列，構(gòu)成一定尺寸的進(jìn)氣口。由于傘衣后緣是完全封閉的，所以上下翼面與各翼肋之間便形成了一個(gè)個(gè)用于儲(chǔ)存空氣的氣室。

SIV是模擬d'Incident en Vol（飛行中的事件模擬）的縮寫，是提供有關(guān)如何應(yīng)對(duì)不穩(wěn)定和潛在危險(xiǎn)情況（例如倒塌，滿是失速和開裂）的課程。這些課程通常由經(jīng)過特殊培訓(xùn)的講師在大片水域上講授，通常通過無線電指導(dǎo)學(xué)生。將指導(dǎo)學(xué)生如何誘發(fā)危險(xiǎn)情況，從而學(xué)習(xí)一旦被誘發(fā)就如何避免和補(bǔ)救。向希望獲得更高性能和更不穩(wěn)定機(jī)翼的飛行員推薦該課程，這對(duì)于大多數(shù)飛行員而言都是自然而然的進(jìn)步。在某些國家，SIV課程是初步飛行員培訓(xùn)的基本要求。萬一出現(xiàn)無法挽回的機(jī)動(dòng)導(dǎo)致水著陸的情況，通常會(huì)派出一艘救援船來收集飛行員。其他增加的安全功能可能包括浮力輔助裝置或輔助備用降落傘。這些課程對(duì)于新手級(jí)別的飛行不是必不可少的。

A paragliding flight over the Mussel Rock

Gliding Bluffs in Pacifica, California

In

flatter countryside, pilots can also be launched with a tow. Once at full

height (towing can launch pilots up to 3000 feet altitude), the pilot pulls a

release cord, and the towline falls away. This requires separate training, as

flying on a winch has quite different characteristics from free flying. There

are two major ways to tow: pay-in and pay-out towing. Pay-in towing involves a

stationary winch that winds in the towline and thereby pulls the pilot in the

air. The distance between winch and pilot at the start is around 500 metres or

more. Pay-out towing involves a moving object, like a car or a boat, that pays

out line slower than the speed of the object, thereby pulling the pilot up in

the air. In both cases, it is very important to have a gauge indicating line

tension to avoid pulling the pilot out of the air. Another form of towing is

"static line" towing. This involves a moving object, like a car or a

boat, attached to a paraglider or hang glider with a fixed-length line. 虹口區(qū)小型滑翔傘多少錢
