These developments were combined in June
1978 by three friends, Jean-Claude Bétemps, André Bohn and Gérard Bosson, from
Mieussy, Haute-Savoie, France. After inspiration from an article on slope
soaring in the Parachute Manual magazine by parachutist and publisher Dan
Poynter,[7] they calculated that on a suitable slope, a "square"
ram-air parachute could be inflated by running down the slope; Bétemps launched
from Pointe du Pertuiset, Mieussy, and flew 100 m. Bohn followed him and glided
down to the football pitch in the valley 1000 metres below.[8]
"Parapente" (pente being French for "slope") was born.
From the 1980s, equipment has continued to
improve, and the number of paragliding pilots and established sites has
continued to increase. The first (unofficial) Paragliding World Championship
was held in Verbier, Switzerland, in 1987,[9] though the first officially
sanctioned FAI World Paragliding Championship was held in Kössen, Austria, in
1989.[10]

The top of each line is attached to small
fabric loops sewn into the structure of the wing, which are generally arranged
in rows running span-wise (i.e., side to side). The row of lines nearest the
front are known as the A lines, the next row back the B lines, and so on.[14] A
typical wing will have A, B, C and D lines, but recently, there has been a
tendency to reduce the rows of lines to three, or even two (and experimentally
to one), to reduce drag.
Paraglider lines are usually made from
Dyneema/Spectra or Kevlar/Aramid.[14] Although they look rather slender, these
materials are immensely strong. For example, a single 0.66 mm-diameter line
(about the thinnest used) can have a breaking strength of 56 kg.[15]
Paraglider wings typically have an area of
20–35 square metres (220–380 sq ft) with a span of 8–12 metres (26–39 ft) and
weigh 3–7 kilograms (6.6–15.4 lb). Combined weight of wing, harness, reserve,
instruments, helmet, etc. is around 12–22 kilograms (26–49 lb).

The glide ratio of paragliders ranges from
9.3 for recreational wings to about 11.3 for modern competition models,[16]
reaching in some cases up to 13.[17] For comparison, a typical skydiving
parachute will achieve about 3:1 glide. A hang glider ranges from 9.5 for
recreational wings to about 16.5 for modern competition models. An idling
(gliding) Cessna 152 light aircraft will achieve 9:1. Some sailplanes can
achieve a glide ratio of up to 72:1.
The speed range of paragliders is typically
20–75 kilometres per hour (12–47 mph), from stall speed to maximum speed.
Beginner wings will be in the lower part of this range, high-performance wings
in the upper part of the range.[note 2]
For storage and carrying, the wing is
usually folded into a stuffsack (bag), which can then be stowed in a large
backpack along with the harness. For pilots who may not want the added weight
or fuss of a backpack, some modern harnesses include the ability to turn the
harness inside out such that it becomes a backpack.
热飞行
托里·派恩斯滑翔伞在空中滑翔伞
当太阳温暖地面时,它将使某些功能比其他功能(例如岩石表面或大型建筑物)加热得更多,而这些功能会引发通过空气上升的热量。有时,这些可能只是空气的简单上升;通常,它们在风中向侧面吹,会从源头脱落,随后形成新的热量。
一旦飞行员找到了热量,他便开始绕圈飞行,试图将圆圈定位在热量**强的部分(“**”)上,其中空气的上升**快。大多数飞行员使用可变高度计(“ vario”),通过嘟嘟声和/或视觉显示来指示爬升率,以帮助将热量插入磁芯中。
通常情况下,周围的热源周围有很强的水槽,当飞行员试图进入强热源时,也存在强烈的湍流,导致机翼塌陷。良好的热力飞行是一项需要花费时间学习的技能,但是好的飞行员通常可以将热力一直贯穿到整个云层。
越野飞行
一旦掌握了使用热量来获得高度的技巧,飞行员就可以从一个热量滑到另一个热量来穿越国家。在热量中获得高度后,飞行员会下滑到下一个可用热量。
潜在的热量可以通过通常会产生热量的陆地特征或积云来识别,这些积云标志着上升的一列温暖,潮湿的空气在到达**并凝结成云时的顶部。
越野飞行员还需要熟悉航空法律,飞行法规,指示空域受限的航空地图等。
滑翔伞驾驶员认证指导计划有几个关键组成部分。对初学者的初步培训通常从一定数量的地面学校开始,以讨论基础知识,包括基本的飞行理论以及滑翔伞的基本结构和操作。
然后,学生将学习如何在地面上控制滑翔机,练习起飞并控制机翼“高架”。接下来是低矮平缓的山丘,学生们可以在低空飞行,以习惯于在各种地形上操纵机翼。在没有丘陵的地区,可以使用特殊的绞车将滑翔机拖至低空。
随着技能的进步,学生们将进入更陡峭/更高的山丘(或更高的绞车拖曳),进行更长的飞行,并学习转动滑翔机,控制滑翔机的速度,然后继续进行360°转弯,点着陆,“大耳朵”
(用于增加滑翔伞的下降速度)和其他更先进的技术。通常通过无线电向学生提供培训说明,尤其是在首飞期间。
完整的滑翔伞教学计划的第三个关键要素是气象,航空法和一般飞行区礼节等关键领域的基本知识。
为了使准飞行员有机会确定他们是否愿意继续进行完整的飞行员培训计划,大多数学校都提供串联飞行,其中经验丰富的教练以准飞行员为乘客驾驶滑翔伞。学校通常会为飞行员的家人和朋友提供乘搭双人飞机的机会,有时还会在度假胜地出售乘搭双人飞机的乐趣。
