<p>A wind turbine (100) includes a rotor assembly (104) having at least one blade (106) with a blade body (130) defining a leading edge (132) and a trailing edge (134) and adapted for movement in response to a wind flow over the body to produce electricity. A rigid acoustic flap (136) extends outward from the trailing edge, and a distal end (140) of the acoustic flap is substantially smooth and continuous. The flap reduces acoustic noise generated by the blade in use.</p> |
