Wind power generator plant

摘要

A wind-power installation (1) includes a generator (2) and a turbine (3) having at least one rotor blade (4), in which a flow-path (5) extending partially in the interior of the rotor blade, flows out at the surface (6) of the rotor blade (4) at a discharge-mouth (7). Heat (18) generated by the generator (2) is transferable to an air-stream (8) in the flow-path (5). Around the rotor blade (4) a flow-stream (9) is generated and depending on its position, has different pressures (10), in which the discharge-mouth (7) lies in a region of low-pressure (10). The rotor blade (4) has a leading edge (11) and a trailing edge (12), in which the mouth (7) is at or in the vicinity of the trailing edge (12).
