Title: VERTICAL-ROTOR WIND TURBINE HAVING AN INTAKE DUCT CONSTRUCTION
Abstract:
The present invention relates to a wind turbine for power generation using frontal incident flow (2) and having a stator and at least one generator driven by a vertical rotor (4). The vertical rotor (4) is connected to the stator such that it can rotate about a vertical axis of rotation (X). At least three rotor blades (7), attached by means of a connection device (6), are arranged on the vertical rotor (4). The rotor blades (7) are oriented on the connection device (6) so as to rotate in the same direction (D). The stator has an intake duct construction having at least four internal faces (9) that surround the vertical rotor (4). The rotor blades (7) are designed in the manner of a wing in horizontal cross section and the intake duct construction comprises two mutually opposite vertical stator vanes (12), which are wing-like in horizontal cross section, and two mutually opposite horizontal stator vanes (13). The stator vanes (12, 13) are designed and arranged such that an air flow generated by the frontal incident flow (2) and flowing through the intake duct construction of the stator is accelerated at least in a boundary region (14) running along the internal faces (9) of the vertical stator vanes (12). The boundary region (14) has a breadth, running horizontally and perpendicular to the frontal incident flow (2), which is less than or equal to a magnitude of a broadest section, horizontally and perpendicular to the frontal incident flow (2), of the vertical stator vanes (12). The rotor blades (7) are designed and arranged at an outer periphery of the vertical rotor (4) such that, at certain points in the rotation of the vertical rotor (4), the rotor blades (7) are completely within the respective boundary region (14) of the stator (3).
