A wind power installation is described having a flow channel (1) between two channel walls (3), at least one of which forms an outer wall of a structure (2), having at least one axial-flow wind turbine (4) which is borne within the flow channel (1), and having a guide device (8) which is mounted in front of the turbine rotor (5) in the incident-flow direction (13) and tapers like a nozzle in the incident-flow direction (13). In order to allow the incident flow to the wind turbine (4) to be controlled in a simple manner, it is proposed that the nozzle-like guide device (8) have at least one guide section (11), which is associated with a channel wall (3), extends substantially around half the circumference of the guide device (8) and is borne on that end face which is remote from the turbine rotor (5) such that it can pivot about a vertical axis (12). |
