I know they inflate into a air foil but why cant you simply blow up the wing into the shape before fight?
HmTough oneCould beI would think because there is less surface area.
For insulation, what is important is the material it is done and how it is positioned (different materials used on the same roof), and not it if flat or anything else.
A paragliding wing works like any aeroplane wingThe air is forced across the top of the wing faster due to the upper wing being more curvedAs it goes faster than the wind under the wing it drops in atmospheric pressure relative to the bottom of the wingThe higher pressure under the wing tries to move into the lower (upper) pressure area and in doing so it lifts the wing upA secondary lifting moment is also caused by the angle of the wing to the airflow which gives a forceful pushing in the same way you get pushed around when walking with a large object in the windA paragliding wing is held in shape by the many lines that go from the wing down to the pilot's harnessThe pilot's weight gives the wing a pendular stability and the forward air speed fills the wing's leading edge (which has openings along it) with air 'pumping up' the wingShould the paraglider encounter bad air turbulence it will collapse but immediately reinflate due to the pendulum effect of the pilot and the wing's forward airspeed.
