IMPROVED WIND TURBINE BLADE CONTROL

The invention relates to a wind turbine blade (5) comprising at least one flow modifying device (51) adapted to modify the airflow so as to provide a control force (CF), located downwind of a shear centre (SC) of the blade (5), so as for the blade (5) to twist to provide a change (dAF) of a lift for...

Beschreibung
Zusammenfassung:	The invention relates to a wind turbine blade (5) comprising at least one flow modifying device (51) adapted to modify the airflow so as to provide a control force (CF), located downwind of a shear centre (SC) of the blade (5), so as for the blade (5) to twist to provide a change (dAF) of a lift force (AF1, AF2) on the blade (5), the lift force (AF1, AF2) including the control force (CF), the change (dAF) being positive in a direction opposite to the direction of the control force (CF). L'invention concerne une pale (5) d'éolienne comprenant au moins un dispositif de modification d'écoulement (51) adapté pour modifier l'écoulement d'air de façon à créer une force de contrôle (CF) située sous le vent d'un centre de cisaillement (SC) de la pale (5) de manière à faire tourner la pale (5) et provoquer un changement (dAF) de la composante de sustentation (AF1, AF2) sur la pale (5), la composante de sustentation (AF1, AF2) comprenant la force de contrôle (CF), la modification étant positive dans un sens opposé au sens de la force de contrôle (CF).
