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]

滑翔傘的機翼或機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,進入的空氣使機翼保持充氣狀態(tài),從而保持其形狀。充氣時,機翼的橫截面具有典型的淚滴翼型形狀?,F(xiàn)代滑翔傘的機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翼中,前緣的某些艙室被封閉以形成更干凈的空氣動力學(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,以使它們膨脹,并向也閉合的翼尖膨脹。

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.



Launching

India

As with all aircraft, launching and landing

are done into wind. The wing is placed into an airstream, either by running or

being pulled, or an existing wind. The wing moves up over the pilot into a

position in which it can carry the passenger. The pilot is then lifted from the

ground and, after a safety period, can sit down into his harness. Unlike

skydivers, paragliders, like hang gliders, do not "jump" at any time

during this process. There are two launching techniques used on higher

ground[20] and one assisted launch technique used in flatland areas:



The next step in the launch is to bring the

wing into the lift zone. There are two techniques for accomplishing this

depending on wind conditions. In light wind this is usually done after turning

to the front, steering with the feet towards the low wing tip, and applying

light brakes in a natural sense to keep the wing horizontal. In stronger wind

conditions it is often found to be easier to remain facing downwind while

moving slowly and steadily backwards into the wind.


Knees bent to load the wing, foot

adjustments to remain central and minimum use of Cs or Brakes to keep the wing

horizontal. Pirouette when the feet are close to lifting. This option has two

distinct advantages. a) The pilot can see the wing centre marker (an aid to

centring the feet) and, if necessary, b) the pilot can move briskly towards the

wing to assist with an emergency deflation.


With either method it is essential to check

"traffic" across the launch face before committing to flight.

  對于普通喜愛戶外運動的人來說,經(jīng)過滑翔傘教練的正規(guī)培訓(xùn),要獨自飛上藍(lán)天其實很easy.客觀的說,滑翔傘飛行是一項休閑航空運動,而非極限運動,只要身體無殘疾、無精神疾病、無癲癇、無心臟病、等疾病的大眾都可以參加.

      在歐洲的四億人中,注冊的滑翔傘飛行員已經(jīng)達到兩百多萬人。而在中國13億人中,學(xué)習(xí)滑翔傘飛行的人少之又少,持有中航協(xié)頒發(fā)的滑翔傘飛行執(zhí)照的飛行員,截止2019年5月才剛好一萬人。中國與歐洲甚至韓國日本的滑翔傘運動水平差距如此之大,是因為這項運動傳入中國大陸較晚,并且中國人的運動觀念保守,有點談“空”色變,只要是與飛行有關(guān)的運動,普通人都敬而遠(yuǎn)之不敢嘗試。其實,滑翔傘運動在歐洲還被戲虐的稱之為“老頭樂”,七、八十歲仍然在飛滑翔傘的人大有人在,飛行對于他們,是一生不變的愛好。 寶山區(qū)原裝滑翔傘詢問報價
