GE rethinks wind turbine blade design to cut noise
Aug 16, 2013 - US conglomerate General Electric Co (NYSE:GE) said Thursday it had joined hands with New Mexico's Sandia National Laboratories to reconsider wind turbine blade design and reduce noise levels.
GE Global Research, the technology development unit of General Electric, said it was already using Sandia’s Red Mesa supercomputer for predicting wind blade noise. By using the results, the firm will try to improve blade design and search for ways to make rotors that have higher power generation and create less noise. According to the company's calculations, a wind turbine rotor which is one decibel quieter will boost the annual turbine production by 2%.
Currently, aerodynamic noise is a major problem in wind turbine blade design, GE Global Research's wind technology platform leader Mark Jonkhof said. "Having access to Sandia’s supercomputer was invaluable in our ability to conduct these experiments and make discoveries that will bolster wind power’s potential," Jonkhof added.
