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]

Paragliding is the recreational and competitive adventure sport of flying paragliders: lightweight, free-flying,
foot-launched glider aircraft with no rigid primary structure.[1] The pilot sits in a harness suspended below a fabric wing. Wing shape is maintained by the suspension lines, the pressure of air entering vents in the front of the wing, and the aerodynamic forces of the air flowing over the outside.
Despite not using an engine, paragliderflights can last many hours and cover many hundreds of kilometres, though flights of one to two hours and covering some tens of kilometres are more the norm. By skillful exploitation of sources of lift, the pilot may gain height,
often climbing to altitudes of a few thousand metres.

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]
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.
著陸涉及更多的計劃，因為可能有多個飛行員必須同時著陸。因此，已經(jīng)建立了特定的流量模式。飛行員排在飛機場上方并降落在降落區(qū)一側(cè)，該位置取決于風向，飛行員可能會因坐飛機而失去身高（如有必要）。從該位置開始，它們以矩形模式沿著飛行路徑的腿到達著陸區(qū)：順風腿進場。這允許在多個飛行員之間進行同步，并減少發(fā)生碰撞的風險，因為飛行員可以預(yù)測他周圍的其他飛行員接下來將要做什么。

在進近下降過程中，在接觸地面大約四米之前，可以施加一些瞬時制動，然后使用向前的擺動動量來獲得速度，以更有效地展開并以**小的垂直速度接近地面。
在小風中，一些小跑很常見。在中等到中等的逆風中，著陸時可能沒有前進速度，甚至在強風中甚至可能相對于地面后退。用風著陸會迫使飛行員向后退，這特別危險，因為它可能會翻滾并被拖拽。當機翼垂直于飛行員上方時，有可能降低風險放氣。這涉及到每只手在槌/豎板交界處抓住前緣線（As），并通過深深的膝蓋彎曲動作來施加飛行員的全部重量。在幾乎每種情況下，機翼的前緣都會向前飛一點，然后“折”。然后，它可能會坍塌并下降到飛行員的上風處。在地面上，它將被飛行員的腿約束。

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。 寶山區(qū)通用滑翔傘價格如何計算
