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.

對(duì)于普通喜愛(ài)戶外運(yùn)動(dòng)的人來(lái)說(shuō),經(jīng)過(guò)滑翔傘教練的正規(guī)培訓(xùn),要獨(dú)自飛上藍(lán)天其實(shí)很easy.客觀的說(shuō),滑翔傘飛行是一項(xiàng)休閑航空運(yùn)動(dòng),而非極限運(yùn)動(dòng),只要身體無(wú)殘疾、無(wú)精神疾病、無(wú)癲癇、無(wú)心臟病、等疾病的大眾都可以參加.
在歐洲的四億人中,注冊(cè)的滑翔傘飛行員已經(jīng)達(dá)到兩百多萬(wàn)人。而在中國(guó)13億人中,學(xué)習(xí)滑翔傘飛行的人少之又少,持有中航協(xié)頒發(fā)的滑翔傘飛行執(zhí)照的飛行員,截止2019年5月才剛好一萬(wàn)人。中國(guó)與歐洲甚至韓國(guó)日本的滑翔傘運(yùn)動(dòng)水平差距如此之大,是因?yàn)檫@項(xiàng)運(yùn)動(dòng)傳入中國(guó)大陸較晚,并且中國(guó)人的運(yùn)動(dòng)觀念保守,有點(diǎn)談“空”色變,只要是與飛行有關(guān)的運(yùn)動(dòng),普通人都敬而遠(yuǎn)之不敢嘗試。其實(shí),滑翔傘運(yùn)動(dòng)在歐洲還被戲虐的稱之為“老頭樂(lè)”,七、八十歲仍然在飛滑翔傘的人大有人在,飛行對(duì)于他們,是一生不變的愛(ài)好。 常州直銷(xiāo)滑翔傘價(jià)格如何計(jì)算
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.

滑翔傘的機(jī)翼或機(jī)蓋通常在工程上稱為“沖壓空氣翼型”。這樣的翼包括兩層織物,它們以形成一排網(wǎng)孔的方式連接到內(nèi)部支撐材料上。通過(guò)使大多數(shù)艙室*在前緣處敞開(kāi),進(jìn)入的空氣使機(jī)翼保持充氣狀態(tài),從而保持其形狀。充氣時(shí),機(jī)翼的橫截面具有典型的淚滴翼型形狀。現(xiàn)代滑翔傘的機(jī)翼是由高性能的無(wú)孔材料制成的,例如尼龍纖維。
在某些現(xiàn)代滑翔傘(從1990年開(kāi)始中,尤其是性能更高的機(jī)翼中,前緣的某些艙室被封閉以形成更干凈的空氣動(dòng)力學(xué)輪廓。內(nèi)部肋骨上的孔允許空氣從開(kāi)孔到這些閉孔的自由流動(dòng),以使它們膨脹,并向也閉合的翼尖膨脹。
飛行員通過(guò)懸吊線網(wǎng)絡(luò)支撐在機(jī)翼下方。這些從兩根短的(40厘米)長(zhǎng)的堅(jiān)固織帶制成的立管開(kāi)始。每組由一個(gè)登山扣固定在吊帶上,飛行員的每一側(cè)上各有一個(gè),每個(gè)組的立管通常*從機(jī)翼一側(cè)的一行上連接到繩索上。在該組的每個(gè)立管的末端,都有一個(gè)小三角洲的馬龍,上面掛有數(shù)行(2 – 5)條線,形成一個(gè)風(fēng)扇。這些線通常長(zhǎng)4 – 5米,末端連接到大約2 m的另外2 – 4條線上,這些線又連接到一組更細(xì)的細(xì)線上。在某些情況下,對(duì)第四級(jí)聯(lián)重復(fù)此操作。
在亞洲,日本、韓國(guó)、中國(guó)的中國(guó)臺(tái)灣省等經(jīng)濟(jì)發(fā)達(dá)國(guó)家和地區(qū)的滑翔傘運(yùn)動(dòng)十分普及,愛(ài)好者達(dá)十多萬(wàn)人。20世紀(jì)80年代末,滑翔傘運(yùn)動(dòng)傳入中國(guó)大陸并迅速發(fā)展,
現(xiàn)注冊(cè)的航空俱樂(lè)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(guó)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(guò)專(zhuān)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。 靜安區(qū)優(yōu)良滑翔傘哪家好

Harness
A pilot with harness (light blue),
performing a reverse launch
The pilot is loosely and comfortably
buckled into a harness, which offers support in both the standing and sitting
positions. Most harnesses have foam or airbag protectors underneath the seat
and behind the back to reduce the impact on failed launches or landings. Modern
harnesses are designed to be as comfortable as a lounge chair in the sitting or
reclining position. Many harnesses even have an adjustable "lumbar
support". A reserve parachute is also typically connected to a paragliding
harness.
Harnesses also vary according to the need
of the pilot, and thereby come in a range of designs, mostly: Training harness
for beginners, Pax harness for tandem passengers that often also doubles as a
training harness, XC Harness for long distance cross country flights, All round
harness for basic to intermediate pilots, Pod harness, which is for
intermediate to pro pilots that focus on XC. Acro harnesses are special designs
for acrobatic pilots, Kids tandem harnesses are also now available with special
child-proof locks.
