היתה קריסה ואם היית יכול לעשות ZOOM-IN היית רואה אותה בברור.לדעתי זה בהחלט נושא לפורום ובעיקר כשחוטפים את זה בגובה נמוך ובתנאים של זכרון ברכיב דרומי משמעותי.
אני בכל זאת חוזר לעניין של הפורוזיטי וההשפעה שלו על ירידת "קשיחות" הכנף ועמידותה בפני קריסות בגלל לחץ נמוך. ואני חוזר לזה מפני שראיתי את הכנף של יונתן וחזותית היא נראית דהויה ו"עייפה"
להלן ציטוט מאתר PAGLIDING-LESSONS.COM:
So how does porosity affect your glider?
New gliders are tested by various agencies/organizations to determine their performance and safety
(See Paragliding Rating System ). When these agencies test gliders, the gliders are new from the factory and
have very little porosity. Because the structure of paragliders is formed by pressurization, the porosity of a glider
also relates to its pressurization. The behavior of a glider will change as the porosity increases. This change in
behavior might be, among other things, glide ratio, speed, resistance to collapses, recovery from collapses,
handling in turns, and surging. In addition to the performance being affected, the durability is affected as well. If a
glider is more porous, it means the material has degraded and it is weaker than it was when you first bought it. If
the material is weaker, it can tear easier. These tears might occur when you are launching or landing near rocks
or sticks. However, if the material of your glider is significantly weaker, it may even tear during an event while
flying, such as a large frontal collapse. Tearing of a glider from a collapse is very unlikely, but it has happened
before.
