Back in December, I wrote about the proposal for a new IEA Task on Quiet Wind Turbine Technology. It was approved by the IEA Wind ExCo at ExCo 78 in Brussels on December 1st 2016. The new task has several confirmed participants from leading organisations with others in discussions to join.
The approved proposal can be found here.
The task has not yet started; we had been seeking funds and resources to put behind the work at Trinity. I will post a further update. In the meantime, please contact your local IEA Wind ExCo representative. You can also email me.
