Record 2 2014-02-20

English

Subject field(s)
  • Aerodynamics and Theory of Gases
  • Wind Energy
DEF

A condition in which the wind's aerodynamic lifting force is approximately equal to its aerodynamic drag, resulting in the lowest wind power capture by the blade.

CONT

Dynamic stall is a non-linear unsteady aerodynamic effect that occurs when aerofoils rapidly change the angle of attack. The rapid change can cause a strong vortex to be shed from the leading edge of the aerofoil, and travel backwards above the wing. The vortex, containing high velocity airflows, briefly increases the lift produced by the wing. As soon as it passes behind the trailing edge, however, the lift reduces dramatically, and the wing is in normal stall.

French

Domaine(s)
  • Théorie des gaz et aérodynamique
  • Énergie éolienne
DEF

Diminution de la portance d'un profil d'aile ou d'hélice par décollement turbulent des filets d'air lorsque l'angle d'incidence dépasse une certaine valeur.

CONT

La diminution de l'angle de calage permet d'atteindre l'angle d'incidence correspondant au décrochage aérodynamique.
