Summary
editDescriptionParapente oreilles incidence.svg |
Français : Faire les oreilles en parapente augmente la trainée, la résultante des forces aérodynamiques (RFA) restant constante. Or la RFA est la somme de la portance et de la trainée, et de plus la trainée est parallele a la trajectoire (et perpendiculaire a la portance), donc la trajectoire s'incurve vers le bas et l'angle d'incidence augmente. Un angle d'incidence élevé peut etre dangereux dans certaines conditions notamment en turbulences pour une aile de parapente car on s'approche de l'incidence de décrochage. |
