Zusammenfassung:	A horizontal-axis downwind turbine (100) is described, comprising a nacelle (150) having a rotor (130) comprising a hub and at least one blade (132), which nacelle (150) is suitable for revolute attachment to a tower (140) thereby defining a rotational axis (151) about which the nacelle (150) yaws, said turbine (100) further comprising: - a hub integrated generator (120); and - a yaw damper (110); wherein the yaw damper (110) comprises a permanent-magnet generator (112), and the blade (132) is swept. L'invention porte sur une turbine sous le vent à axe horizontal (100) comprenant une nacelle (150) ayant un rotor (130) qui comprend un moyeu et au moins une pale (132), laquelle nacelle (150) est apte à se fixer avec possibilité de rotation à une tour (140) en définissant ainsi un axe de rotation (151) autour duquel la nacelle (150) décrit un mouvement de lacet, ladite turbine (100) comprenant en outre : - une génératrice intégrée au moyeu (120); et - un amortisseur de lacet (110); l'amortisseur de lacet (110) comprenant une génératrice à aimant permanent (112) et la pale (132) étant animée d'un mouvement de balayage.
