WIND TURBINE BLADE WITH RAKE OF UPWIND DIRECTION

摘要

PURPOSE: A wind turbine wing having a rake of a windward direction is provided to prevent an accident that a wing in which a deformation is generated with an aerodynamic force collides with a tower, although a wind force turbine shaft maintains horizontal. CONSTITUTION: A wind turbine wing having a rake of a windward direction comprises a wing altogether having a rake to a windward direction while a turbine shaft is horizontally installed. A wing having a rake to a front prevents an accident that a wing in which a deformation is generated with an aerodynamic force collides with a tower, although a wind force turbine shaft maintains a horizontal. A shafting arrangement inside a nacelle is considerably facilitated when a wind force turbine shaft is horizontally set up.
