4 FAQs about People stepped on the wind turbine blades and damaged them

What causes blade failures in wind turbines?

It's crucial to monitor their condition closely to ensure optimal performance and safety. Let's explore some common types of surface damage observed that lead to blade failures in wind turbines. If damage or impairments remain undetected, this can have costly consequences and lead to blade failures in wind turbines.

How are wind turbine blade failure mechanisms analyzed?

Generally, failure mechanisms of wind turbine blades are analyzed using the following main methods: Computational modelling of blade deformation and damage. Post-mortem analysis of failed or damaged blades (either test blades or blades taken from old or damaged wind turbines) is the most obvious approach to explore the blade failure mechanisms.

What causes a wind turbine to stop working?

Apart from force majeure situations when the wind turbines cannot function anymore (lightning, tower hit by blade, transport damage, missing external parts), they listed interlaminar failure, transverse cracks from the trailing edge and on the blade surface, fatigue failure in the root connection as critical damage requiring the turbine to stop.

Are wind turbine blades prone to damage & breakdown?

We see that in the survey published in 2016, damage to and failure of wind turbine blades comes first in 5th place. Recent research clearly shows that the wings are the component most exposed to damage and breakdown. We recall an earlier quote confirming this change: We look further at the findings of Carroll and colleagues (2016).
