無動(dòng)力滑翔傘是借助傘翼在空中相對(duì)空氣的運(yùn)動(dòng)產(chǎn)生的升力，由飛行員通過操縱繩控制速度、方向等，實(shí)現(xiàn)無動(dòng)力滑翔傘自由翱翔的。它起源于法國(guó)，于上世紀(jì)八十年代傳入中國(guó)，截至目前，國(guó)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(yùn)動(dòng)。
請(qǐng)記住，滑翔傘不是降落傘，降落傘是“可展式氣動(dòng)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(jiǎn)易的飛行器，它能借助對(duì)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。 青浦區(qū)滑翔傘價(jià)格
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.

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。通過使大多數(shù)艙室*在前緣處敞開，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?，F(xiàn)代滑翔傘的機(jī)翼是由高性能的無孔材料制成的，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。
In some modern paragliders (from the 1990s
onwards), especially higher-performance wings, some of the cells of the leading
edge are closed to form a cleaner aerodynamic profile. Holes in the internal
ribs allow a free flow of air from the open cells to these closed cells to
inflate them, and also to the wingtips, which are also closed.[13]
The pilot is supported underneath the wing
by a network of suspension lines. These start with two sets of risers made of
short (40 cm) lengths of strong webbing. Each set is attached to the harness by
a carabiner, one on each side of the pilot, and each riser of a set is generally
attached to lines from only one row of its side of wing. At the end of each
riser of the set, there is a small delta maillon with a number (2 – 5) of lines
attached, forming a fan. These are typically 4 – 5 metres long, with the end
attached to 2 ? 4 further lines of around 2 m, which are again joined to a
group of smaller, thinner lines. In some cases this is repeated for a fourth
cascade.
Land-based practice: Kiting
About that time, David Barish was
developing the "sail wing" (single-surface wing) for recovery of NASA
space capsules – "slope soaring was a way of testing out ... the Sail
Wing."[5] After tests on Hunter Mountain, New York, in September 1965, he
went on to promote slope soaring as a summer activity for ski resorts.[6][7]
Author Walter Neumark wrote Operating
Procedures for Ascending Parachutes, and in 1973 he and a group of enthusiasts
with a passion for tow-launching PCs and ram-air parachutes broke away from the
British Parachute Association to form the British Association of Parascending Clubs
(which later became the British Hang Gliding and Paragliding Association). In
1997, Neumark was awarded the Gold Medal of the Royal Aero Club of the UK.
Authors Patrick Gilligan (Canada) and Bertrand Dubuis (Switzerland) wrote the
first flight manual, The Paragliding Manual in 1985, coining the word
paragliding.
