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. 5, record 1, English, - aerodynamic%20stall

In blade testing, static loads may be useful for evaluating stiffness and ultimate strength of a turbine blade. However, in practice, the load on a wind turbine blade varies constantly and to evaluate fatigue resistance of the blade, a cyclical load may be applied in large test facilities. 1, record 2, English, - %20fatigue%20resistance%20of%20the%20blade

Dans le cas d’une machine [éolienne] régulée au décrochage et dans des conditions de fonctionnement proches du décrochage, une modification rapide de la vitesse du vent(rafale) peut initier un mouvement d’oscillation en torsion, combinant les effets du décrochage dynamique(dû à la variation instationnaire de l'angle d’incidence), de la force centrifuge et de l'élasticité intrinsèque de la pale. La machine peut ainsi se trouver soumise à un phénomène entretenu, rarement divergent mais pouvant affecter la tenue en fatigue de la pale. 1, record 2, French, - tenue%20en%20fatigue%20de%20la%20pale
