A windmill comprising a rotor having a substantially horizontal axis of rotation (1a) and at least two blades (4) extending along a respective blade axis, about which the blade can be rotated to an adjustment angle for the blade, and a blade adjusting device (11, 13) for adjusting a common basic angle of adjustment for the blades (4), said windmill further comprising means (14) for detecting the size of the basic angle of adjustment, means for detecting the load on the windmill and means (15-22) for detecting the deflection of the blade, preferably in the direction of the axis of the rotor (1a), is controlled according to the invention by adjustment of the basic angle of adjustment, a control signal for the blade adjusting device being provided in dependency of the load and the wind speed, and, as a measure for the wind speed, the deflection .alpha. of the blade is used, preferably in the direction of the rotational axis (1a) of the rotor.

Une éolienne comprend un rotor possédant un axe de rotation sensiblement horizontal (1a) et au moins deux pales (4) qui s'étendent le long d'un axe de pâle correspondant autour duquel on peut faire pivoter la pale selon un angle d'ajustement de la pale, et un dispositif d'ajustement de pales (11, 13) destiné à ajuster un angle de base commun pour les pales (4), ladite éolienne comprenant également des moyens (14) pour détecter la valeur d'un angle d'ajustement de base commun, des moyens pour détecter la charge de l'éolienne et des moyens (15-22) pour détecter la déflexion de la pale, de préférence dans la direction de l'axe du rotor (1a). Selon l'invention, l'éolienne est commandée par l'ajustement de l'angle d'ajustement de base; un signal de commande pour le dispositif d'ajustement est émis en fonction de la charge et de la vitesse du vent et, en tant que mesure de la vitesse du vent, on utilise la déflexion (.alpha.) de la pale, de préférence dans la direction de l'axe de rotation (1a) du rotor.
