6 FAQs about [The leading edge of the wind turbine blade]

Do wind turbine blades have a leading edge?

The following review evaluates for wind turbine blades, the prominent types of environmental exposure, the nature of their interaction with the blade leading edge and the robustness of leading edge material technologies, in order to better define the issue of leading edge erosion and impact damage. 2. Utility scale wind turbine design and operation

Do wind turbine blades protect against leading edge erosion?

7. Conclusions Recent developments in the wind turbine blade protection against leading edge erosion, are reviewed, on the basis of last year publications, works presented on the annual DTU symposia on leading edge erosion over last four years, as well as studies carried out at DTU Wind.

Are wind turbine blades eroded?

The ideas and results, presented at the annual symposia on erosion of wind turbine blades, organized at DTU Wind since 2020, are reviewed. Recent studies of leading edge erosion, devoted to the computational analysis and materials science aspects of the erosion, are summarized.

How does rain affect wind turbine blade leading edge erosion?

In the context of wind turbine blade leading edge erosion, the freefalling terminal velocity of the rain droplet plays only a minor role in the magnitude of the impact velocity when compared to the blade tip speeds.

Why is blade leading edge erosion important?

Blade leading edge erosion has become an important issue for the offshore wind industry. The performance of a wind turbine is largely dependent on the aerodynamic properties of its blades. Leading edge erosion is caused by raindrops, hailstones or other particles impacting the leading edge of the blade.

Why did DTU Wind organize a symposia on leading edge erosion of wind turbine blades?

In order to get better overview of lately developed solutions, DTU Wind organized a series of international symposia on leading edge erosion of wind turbine blades in 2020–2023, inviting specialists from research teams and projects active in this area.
