IEA Wind TCP Task 46

Erosion of Wind Turbine Blades

About Task 46

Leading-edge erosion (LEE) has been identified as the main factor substantially reducing both blade lifetime and energy output over time. Field repairs are costly due to lost availability and challenging access and weather conditions. It is crucial to understand the impact of leading-edge erosion on the performance of wind plants to be able to determine the cost/benefit of proposed mitigation strategies.

In this context, Task 46 has been formed by experts from different disciplines to work together to achieve a better understanding of the key technical challenges in blade erosion. The Task will produce literature surveys, topical reports, recommended practices, and models.

The Task 46 scope is aligned to two research priorities established by IEA TCP Wind: site characterization and advanced technology.

Task 46 Participants

Who can participate in Task 46?

To participate in the research activities of Task 46, researchers must reside in a country that participates in the IEA Wind Agreement AND has agreed by official letter to participate in Task 46. The participating member country of the IEA Wind TCP must designate a lead institution that agrees to the obligations of Task participation (pay the annual fee and agree to perform specified parts of the work plan).

Active researchers (performing part of the work plan) benefit from meetings and professional exchange during the term of the Task. Countries participating in the Task benefit from the information developed by the Task. The value of the research performed is many times the cost of the country participation fee or the labor contributed to carrying out the work plan.

    What are IEA Wind Tasks?

    The IEA Wind Technology Collaboration Programme’s (TCP) cooperative efforts continue to advance the technological development and global deployment of wind energy technology. The IEA Wind TCP is a vehicle for member countries to exchange information on the planning and execution of national large-scale wind system projects, and to undertake co-operative research and development (R&D) projects called Tasks.
