滑翔傘錦標(biāo)賽開幕式在大明山舉行,來自國(guó)內(nèi)46名前列滑翔傘運(yùn)動(dòng)員參加此次錦標(biāo)賽。航空運(yùn)動(dòng)管理中心辦公室主任葉正福、自然保護(hù)區(qū)管理局滕達(dá)初副局長(zhǎng)參加開幕式并致辭。

葉正福表示,滑翔傘運(yùn)動(dòng),作為航空運(yùn)動(dòng)的重要項(xiàng)目之一,在我區(qū)起步雖晚,但發(fā)展勢(shì)頭強(qiáng)勁。近幾年,滑翔運(yùn)動(dòng)如雨后春筍般在八桂大地上發(fā)展壯大,處處開花。通過大家的不懈努力,現(xiàn)在,廣西的滑翔傘運(yùn)動(dòng)產(chǎn)業(yè)已初具規(guī)模。此次錦標(biāo)賽的舉辦,為發(fā)展我區(qū)滑翔運(yùn)動(dòng),提高我區(qū)滑翔運(yùn)動(dòng)競(jìng)技水平提供難得的機(jī)遇。

滕達(dá)初表示,本次賽事的舉辦,將極大促進(jìn)大明山“山地戶外運(yùn)動(dòng)”旅游品牌的打造,為塑造廣西大明山——“中國(guó)·東盟戶外運(yùn)動(dòng)中心”品牌助力。作為戶外運(yùn)動(dòng)會(huì)重要活動(dòng)之一的滑翔傘錦標(biāo)賽,也將打造廣西大明山航空旅游的新名片,進(jìn)一步提高廣西航空體育運(yùn)動(dòng)旅游、體育旅游的競(jìng)爭(zhēng)力,進(jìn)一步提高大明山**度,將大明山戶外運(yùn)動(dòng)聚集地形象推至全國(guó)乃至世界。

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.

This can be very dangerous, because now the

forces on the line have to be controlled by the moving object itself, which is

almost impossible to do, unless stretchy rope and a pressure/tension meter

(dynamometer) is used. Static line towing with stretchy rope and a load cell as

a tension meter has been used in Poland, Ukraine, Russia, and other Eastern

European countries for over twenty years (under the name Malinka) with about

the same safety record as other forms of towing.[21] One more form of towing is

hand towing. This is where 1?3 people pull a paraglider using a tow rope of up

to 500 feet. The stronger the wind, the fewer people are needed for a

successful hand tow.[22] Tows up to 300 feet have been accomplished, allowing

the pilot to get into a lift band of a nearby ridge or row of buildings and

ridge-soar in the lift the same way as with a regular foot launch.[23]



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)過來的情況下,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)飛行員從來沒有理由“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,飛行員通常沒有足夠的剩余高度來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。




盡可能避免降落對(duì)機(jī)翼過大的風(fēng)。在接近預(yù)定著陸點(diǎn)的過程中,這種潛在問題通常很明顯,并且可能有機(jī)會(huì)擴(kuò)大飛行范圍,以找到更庇護(hù)的著陸區(qū)域。在每次著陸時(shí),都希望機(jī)翼保持可飛行狀態(tài),并具有少量前向動(dòng)量。這使放氣更加可控。盡管中線(Bs)是垂直的,但是機(jī)翼快速順風(fēng)移動(dòng)的機(jī)會(huì)要少得多。常見的放氣提示來自后提升板管線(Cs或Ds)上的劇烈拉力。迅速旋轉(zhuǎn)以迎面迎風(fēng),在后立管上保持壓力,并在機(jī)翼掉落時(shí)朝機(jī)翼輕快邁進(jìn)。通過實(shí)踐,有可能實(shí)現(xiàn)精確的安全“無故障停車”。


對(duì)于著陸進(jìn)場(chǎng)期間的強(qiáng)風(fēng),“拍打”機(jī)翼(制動(dòng)器對(duì)稱脈動(dòng))是**終的常見選擇。它會(huì)降低機(jī)翼的升力性能。通過交替施加和釋放制動(dòng)器,下降速度大約每秒一次。該系統(tǒng)取決于飛行員對(duì)機(jī)翼的熟悉程度。機(jī)翼不得停轉(zhuǎn)。應(yīng)在飛行中,安全高度,良好條件下,并由觀察員提供反饋的情況下,輕柔地進(jìn)行安裝。通常,制造商會(huì)根據(jù)批準(zhǔn)重量范圍內(nèi)飛行員的平均身體比例來設(shè)定安全制動(dòng)行程范圍。應(yīng)該以小幅增加對(duì)該設(shè)置進(jìn)行更改,并在帶有說明性標(biāo)記的情況下顯示這些變化,并進(jìn)行試飛以確認(rèn)所需的效果??s短制動(dòng)管路會(huì)產(chǎn)生使機(jī)翼變慢的問題。過度加長(zhǎng)制動(dòng)器會(huì)使機(jī)翼難以達(dá)到安全的著陸速度。

Europe has seen the greatest growth in

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

Wing

Cross section of a paraglider

Transverse cross section showing parts of a

paraglider:

1) upper surface

2) lower surface

3) rib

4) diagonal 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]
