Wind turbine |
| 摘要 |
In order to reduce the noise nuisance caused during operation by rotor blades of a rotor of a wind turbine the rear edge of each blade is irregularly formed. In particular the saw-tooth form with a top angle smaller than about 150 DEG and preferably 10 DEG is found to produce a considerable noise reduction.
