Innovative Serration Design
An innovative 3D geometry for TES allows an increase in noise reduction of up to 5 dB(A) in comparison to 2 dB(A) achieved by exisiting geometries based on 2D designs. 6 dB(A) corresponds to a halving of the audible noise. This helps to avoid night shutdowns leading to an additional yield of up to 20 %. For new turbines this allows the use of longer rotor blades.
