For a partial check and even a small repair, we perform a single measurement in the center of the wing, in the area where the porosity is strongest.
We do not want to work on a sail that would no longer be fit for flight!
A paraglider becomes porous when the coating of the fabric is mechanically altered by the folding of the fabric and chemically by moisture and heat. Note that the coating is also there to stiffen the fabric especially in the bias and that a porous veil deforms!!!
Fortunately, it is only when the porosity is really very high that it can affect the behaviour in flight. But when this happens, it is very serious, because it makes the glider slower, the stall closer and even a likely stable parachute phase.
FREE OF CHARGE | for the safety of all!
At your request, we perform this porosity measurement free of charge on your paraglider, but it is you who unfold and put your equipment back in its bag!
