Abstract: 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.
A preliminary analysis of the Vineyard Wind turbine that failed has found that, although the fundamental design of the machine’s 351-foot blades is sound, a manufacturing flaw caused one of.
Corrosion and contamination at the leading edge of wind turbine blades is one of the key problems in wind power production, as shown in Figure 5. Erosion and contamination at the leading edge of the blade results in an increase in the resistance coefficient and a corresponding decrease in lift coefficient, which reduce the generation of .

6 FAQs about [Wind turbine blades fall off during power generation]
Are giant wind turbines falling over?
Giant Wind Turbines Keep Mysteriously Falling Over. This Shouldn't Be Happening. The taller the turbine, the more epic the tumble. Turbine failures are on the uptick across the world, sometimes with blades falling off or even full turbine collapses. A recent report says production issues may be to blame for the mysterious increase in failures.
Why do wind turbine blades fail?
Critical role of interfaces and bonding layers: Apart from leading edge erosion (which is a multiphysical, mainly microscale process), the failure mechanisms of wind turbine blades are often triggered by interface debonding, delamination and thin layer (interply, adhesive layer) degradation, which interact with composite buckling processes.
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.
How do we investigate failure mechanisms of wind turbine blades?
Methods of investigation of failure mechanisms of wind turbine blades include the full scale testing of blades in laboratories, a post-mortem analysis of failed blades, analysis of incident reports and computational modelling.
Can a wind turbine blade be pulled from its hub?
As a result of root end failure, the blade can be pulled from its hub during the service time. Lee et al. reported that blade failures observed in the field at Eclipse and Ocotillo wind farm in 2013 were caused by pulling out the blades from the wind turbines due to delamination at the root.
Why are so many turbines falling off?
The taller the turbine, the more epic the tumble. Turbine failures are on the uptick across the world, sometimes with blades falling off or even full turbine collapses. A recent report says production issues may be to blame for the mysterious increase in failures. Turbines are growing larger as quality control plans get smaller.
