Destruction-free installation of wind turbine blades

Why do wind turbine blades fail?

Multiple requests from the same IP address are counted as one view. A review of the root causes and mechanisms of damage and failure to wind turbine blades is presented in this paper. In particular, the mechanisms of leading edge erosion, adhesive joint degradation, trailing edge failure, buckling and blade collapse phenomena are considered.

Do wind turbine blades erode?

Still, the erosion (as said) is most often observed and is the earliest observed damage mechanism of wind turbine blades (1…2 years after installation [ 19 ]), which can lead to a reduction in the annual energy production of wind turbines (5% and more) and a reduction in further damage in the laminates. 3.2. Tapered Areas and Plydrop

How much damage does a wind turbine blade have?

The blade damage is classified into seven types mentioned in Refs. [8, 9]. The damage areas on wind turbine blades (WTBs) easily occur at 30–35% and 70% in chord length from the blade root, the root of the blade, maximum chord, and upper spar cap/flange of the spar.

How do wind turbines protect their blades from damage?

The operating strategies for wind turbines to mitigate any possible damage to their blades are based on early detection and the actions required to prevent damage from becoming severe enough to negatively affect their operations and repair costs.

Can fatigue damage wind turbine blades?

Damage to wind turbine blades due to fatigue can be prevented with two alternative approaches: adequate prediction of the blade’s material behaviour versus fatigue and its structural properties appropriate selection of the wind park’s installation site and the optimum siting of the wind turbines.

How has technology influenced wind turbine blade design?

The evolution of wind turbine blade design has been significantly influenced by technological advancements, leading to innovative configurations that maximize energy capture and efficiency.
