The angle at which the airfoil meets the relative airflow is called the angle of attack. As the angle of attack is increased, the changes in pressure over the upper and lower surfaces and the amount of downwash (i.e. air deflected downward) increase up to a point (the stalling angle). Beyond this angle, they decrease. 4, record 2, English, - angle%20of%20attack

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 3, English, - aerodynamic%20stall

The two principal means of limiting rotor power in high operational wind speeds - stall regulation and pitch regulation ... Stall regulated machines require speed regulation. As wind speed increases, providing the rotor speed is held constant, flow angles over the blade sections ... The blades become increasingly stalled and this limits power to acceptable levels without any additional active control. For this to work, the speed of the WT [wind turbine] rotor must be held essentially constant and this is achieved through the connection of the electric generator to the grid. 4, record 9, English, - stall%20regulation

Flottement et divergence statique. Lorsqu'une pale(articulée ou encastrée) est animée d’un mouvement de battement, elle est soumise à des efforts inertiels qui s’appliquent le long de l'axe massique(lieu des centres de gravité). Parallèlement, la pale est soumise à des efforts aérodynamiques qui s’appliquent le long de l'axe aérodynamique(lieu des foyers) […] La divergence statique se rencontre dans les conditions suivantes : la rigidité en torsion de la pale est très faible et la pale est centrée arrière(axe massique situé nettement en arrière de l'axe élastique). Lorsque la pale est déformée en battement, l'effort centrifuge génère un moment de torsion qui est suffisant, en raison de la faible rigidité en torsion, pour provoquer une augmentation significative de l'angle d’incidence, pouvant amener le décrochage de la pale. Ce type d’oscillation peut se rencontrer par exemple dans le cas de rupture de la commande de pas d’une machine à pas variable dont les pales sont centrées arrière. Au cours d’un tour du rotor, la pale qui est alors «folle» autour de l'axe de pas(raideur nulle en torsion) décroche et sort du décrochage à la fréquence de rotation de l'éolienne. 1, record 11, French, - divergence%20statique

A wind turbine blade regulation system that, when the machine reaches its rated power, and the generator is about to be overloaded, pitches the blades in the opposite direction from what a pitch controlled machine does, hence increasing the angle of attack of the rotor blades in order to make the blades go into a deeper stall, thus wasting the excess energy in the wind. 3, record 13, English, - active%20stall%20regulation

stall regulation. The blades on a stall-regulated-WT [wind turbine] cannot be pitched. To achieve control of power captured above rated wind speed, the blades are carefully designed so that they progressively stall starting at the blade root and moving out towards the tip as the wind speed increases further. Stall-regulated WTs will respond much more quickly to gusts than pitch-regulated WTs (where mecanic pitch adjustments take finite amounts of time to effect), improving the power quality output by the WT above rated wind speed. 1, record 15, English, - stall%2Dregulated%20blade
