About Task 47

The aim of IEA Task 47 is to cooperate on the field of detailed aerodynamic measurements on MW scale wind turbines. Such measurements are extremely difficult to do and the only public example until now is the Danish DanAero experiment which was used in IEA Task 29. Recently several other countries initiated new experiments for turbines up to a scale of 8MW and they now all have to go through a similar learning process on these new measurement techniques. Sharing experiences is then a very fruitful way to steepen the learning curves.

The Task also includes analysis of aerodynamic measurements where moreover simulations are carried out on the 15 MW Reference Wind Turbine from IEA Task 37. These simulations give insight into the relevant aerodynamic problems for large scale wind turbines which is important information for the definition of the experimental programs.

Task 47 Roadmap

The Task 47 begin date is January 1st 2021 after which it will run for 4 years until December 31st 2024. A detailed planning of the activities can be found under the tab Work Plan and Objectives.

For now the most important event is the kick-off meeting which will be held on-line in three sessions of 2.5 hours on April 6, 8 and 9 2021. At this meeting the planning of activities will be refined and detailed for the coming period.

The schedule of personal meeting is put on hold due to the Corona pandemic. If the situation improves personal meetings will be organised again. It is anticipated that they will be held on an annual basis, mostly in Europe in view of the fact that the majority of the participants is European but meetings in the US and China are anticipated too.
