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]

滑翔伞拖曳发射，波兰米罗斯瓦维采

滑翔伞降落在印度Azheekkod海滩

与所有飞机一样，发射和降落都是在风中完成的。机翼通过奔跑或被拉动或存在的风被置于气流中。机翼在飞行员上方向上移动到可以运载乘客的位置。然后将飞行员从地面抬起，经过一段安全时期后，可以坐在他的安全带中。与跳伞运动员不同，滑翔伞与悬挂式滑翔伞一样，在此过程中不会随时“跳”起来。在高地上使用了两种发射技术[20]，在平地地区使用了一种辅助发射技术：

向前发射

在低风中，机翼通过向前发射而膨胀，飞行员在前进时将机翼向后移动，以便向前运动产生的气压使机翼膨胀。

这通常更容易，因为飞行员只需要向前跑，但是飞行员直到机翼上方都看不到他的机翼为止，在那里他必须在很短的时间内检查一下机翼，以确保发射前有正确的充气和不纠缠的线。 苏州原装滑翔伞省钱

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]

大风降落的替代方法包括使用速度杆和大耳朵。速度杆可增加机翼的穿透力，并增加垂直下降率的少量增加。这使得在正式电路中更容易调节下降率。在极端情况下，建议您在离开线束后站在速度杆上，并保持在速度杆上，直到着陆和放气为止。大耳朵通常在电路高度管理期间使用。垂直下降速度增加，并且可以利用该优点将滑翔机带到适当的电路连接高度。大多数制造商都在高级机型中改变了大耳朵的操作技术。放开控制线后，C级滑翔机的大耳朵通常会保持折叠状态。在那种情况下，机翼可以大耳朵部署，以合理的安全降落。在那些机翼类型中，通常需要两到三个带有制动器的对称泵，再过一到两秒钟才能重新给叶尖充气。在较低额定值的机翼中，“大耳朵”需要保持固定状态以将耳朵固定。当它们固定在机翼中时，机翼往往会对侧倾轴上的重量变化（由于有效面积减小）产生更好的响应。释放管线后，它们会自动重新充气。通常，这些机翼更适合拉入耳朵以摆脱多余高度的情况。然后应在基脚或着陆前几秒钟恢复全翼飞行。机翼熟悉度是应用这些控件的关键要素。飞行员应在中等条件下在安全区域，安全高度和有降落选项的情况下练习。

飞行中的机翼放气（崩溃）

由于机翼（机翼）的形状是由进入机翼并使之膨胀的运动空气形成的，因此在湍流的空气中，机翼的一部分或全部会收缩（塌陷）。被称为“主动飞行”的飞行员技术将**降低通气或坍塌的频率和严重性。这种通缩通常无需飞行员干预即可恢复。如果发生严重的放气，正确的飞行员输入将加快从放气中恢复的速度，但是错误的飞行员输入会减慢滑翔机返回正常飞行的速度，因此飞行员必须进行正确的训练和练习以应对放气。

在极少数情况下，无法从通缩中恢复（或从诸如旋转等其他威胁性状况中）恢复过来的情况下，大多数飞行员会携带备用（救援，紧急情况）降落伞。但是，大多数飞行员从来没有理由“扔”他们的储备。如果机翼在低空发生放气，即在起飞后不久或着陆前不久，机翼（滑翔伞）可能无法迅速恢复其正确的结构以防止发生，飞行员通常没有足够的剩余高度来部署后备力量降落伞[**小降落高度大约为60 m（200 ft），但通常在稳定期使用120-180 m（390-590 ft）的高度进行典型部署]。备用降落伞的不同包装方式会影响其部署时间。

In

flatter countryside, pilots can also be launched with a tow. Once at full

height (towing can launch pilots up to 3000 feet altitude), the pilot pulls a

release cord, and the towline falls away. This requires separate training, as

flying on a winch has quite different characteristics from free flying. There

are two major ways to tow: pay-in and pay-out towing. Pay-in towing involves a

stationary winch that winds in the towline and thereby pulls the pilot in the

air. The distance between winch and pilot at the start is around 500 metres or

more. Pay-out towing involves a moving object, like a car or a boat, that pays

out line slower than the speed of the object, thereby pulling the pilot up in

the air. In both cases, it is very important to have a gauge indicating line

tension to avoid pulling the pilot out of the air. Another form of towing is

"static line" towing. This involves a moving object, like a car or a

boat, attached to a paraglider or hang glider with a fixed-length line. 嘉定区官方滑翔伞便宜
