On analytical tools for assessing the raindrop erosion of wind turbine blades

In renewable energy, wind capture has been expanding to now have one of the largest presences in global green energy sector. With drive expand low carbon technologies; maintenance engineering components turbines is crucial and particular monitoring leading edge turbine blades which experience high impact velocities service. Surface changes due rain drop erosion can reduce conversion a loss aerodynamic efficiency. This key areas interest, as even small lead 2–3% annual energy. Inspection methodologies are basic, involving an observation high-definition photographs damage. Recent studies on blade materials show that this standard procedure often fails characterise efficiency these in. industry moving direction leading-edge profile samples, there consensus whirling arm type test rigs most applicable testing regimes.
