SYSTEM AND METHOD FOR ATTENUATING THE NOISE OF AIRFOILS |
摘要 |
A system and method for reducing the noise of an airfoil is provided. The airfoil includes a main portion including a leading edge and a trailing edge. The airfoil further comprises a noise attenuator coupled to the main portion and disposed proximate to at least a portion of the trailing edge. The noise attenuator has a chord length in the range of about 0.5 to about 5 times a trailing edge thickness and is fixed relative to the trailing edge. The airfoil can be a rotating blade deployed on a wind turbine. The airfoil can also be deployed on an aircraft as a fixed wing.
