  • Windturbine and building having such a wind turbine
    Patent number: 9951628
    Abstract: Wind turbine (1) comprising a rotor (2) around a rotation shaft (3), having a plurality of blades (4) at a distance around the rotation shaft (3), in which the blades (4) can drive the rotor (2); a cavity (10) which extends between the ends (15) of the blades (4) closest to the rotation shaft (3); a plurality of vanes (5) around the rotor (2) for guiding wind to the blades (4), in which the vanes (5) extend from the ends (14) of the blades (4) furthest from the rotation shaft (3) to a second end (16) of the vanes (5). The vanes (5) and blades (4) merge into each other at the same curvature mathematically tangentially in a plane at right angles to the rotation shaft (3) and the curvature of the vanes (5) is described by a part of a logarithmic spiral.
