无动力滑翔伞是借助伞翼在空中相对空气的运动产生的升力,由飞行员通过操纵绳控制速度、方向等,实现无动力滑翔伞自由翱翔的。它起源于法国,于上世纪八十年代传入中国,截至目前,国内的持证滑翔伞飞行员刚刚过万人,是极富魅力与想象力并且很厉害的潮人运动。
请记住,滑翔伞不是降落伞,降落伞是“可展式气动阻力器”,它能让人或物体从空中以较小的匀速下降。而滑翔伞是人类目前创造出的简易的飞行器,它能借助对流层中的热气流越飞越高,直到云底或者热气流消散的积云顶端。 小型滑翔伞价格如何计算
尽可能避免降落对机翼过大的风。在接近预定着陆点的过程中,这种潜在问题通常很明显,并且可能有机会扩大飞行范围,以找到更庇护的着陆区域。在每次着陆时,都希望机翼保持可飞行状态,并具有少量前向动量。这使放气更加可控。尽管中线(Bs)是垂直的,但是机翼快速顺风移动的机会要少得多。常见的放气提示来自后提升板管线(Cs或Ds)上的剧烈拉力。迅速旋转以迎面迎风,在后立管上保持压力,并在机翼掉落时朝机翼轻快迈进。通过实践,有可能实现精确的安全“无故障停车”。
对于着陆进场期间的强风,“拍打”机翼(制动器对称脉动)是**终的常见选择。它会降低机翼的升力性能。通过交替施加和释放制动器,下降速度大约每秒一次。该系统取决于飞行员对机翼的熟悉程度。机翼不得停转。应在飞行中,安全高度,良好条件下,并由观察员提供反馈的情况下,轻柔地进行安装。通常,制造商会根据批准重量范围内飞行员的平均身体比例来设定安全制动行程范围。应该以小幅增加对该设置进行更改,并在带有说明性标记的情况下显示这些变化,并进行试飞以确认所需的效果。缩短制动管路会产生使机翼变慢的问题。过度加长制动器会使机翼难以达到安全的着陆速度。

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.
Paragliders are unique among human-carrying
aircraft in being easily portable. The complete equipment packs into a rucksack
and can be carried easily on the pilot's back, in a car, or on public
transport.[14] In comparison with other air sports, this substantially
simplifies travel to a suitable takeoff spot, the selection of a landing place
and return travel.
Tandem paragliders, designed to carry the
pilot and one passenger, are larger but otherwise similar. They usually fly
faster with higher trim speeds, are more resistant to collapse, and have a
slightly higher sink rate compared to solo paragliders.
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]

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.
