Testing low-noise rotor blades in the wind tunnel. Combine aeroacoustic profile design with passive noise reduction methods.

Artikel

The expected noise emissions and the resulting necessary distance to residential buildings are of great importance in the approval of wind farms. In order to reduce these emissions, scientists have designed a powerful rotor blade profile that is as low-noise as it is aerodynamically efficient and have tested the corresponding specimens in wind tunnels. These specimens were combined with passive reduction technologies on the trailing edge and modified blade tips. During the experiment, subject to the operating conditions, noise reductions of up to eight decibels were achieved.
