Wind turbine blade grinding

How to calibrate wind turbine blades?

Hu et al. proposed a calibration approach for wind turbine blades using the laser displacement sensor (PSD) combined with the point cloud registration method. First, the nine-point fitting method was used to measure the blade surface landmark points, and then the ICP method was used to calibrate the local point cloud.

Do wind turbine blades lose material properties during chemical treatment?

In addition, during chemical treatment, fiber materials reclaimed from wind turbine blades can lose their material properties (Paulsen and Enevoldsen, 2021). Incineration is a representative thermal treatment method for treating wind turbine blades (Kalkanis et al., 2019).

Can wind turbine blades be treated by incineration?

Incineration is a representative thermal treatment method for treating wind turbine blades (Kalkanis et al., 2019). Heat and electricity can be generated by incinerating wind turbine blade waste in combined heat and power (CHP) plants.

What are the technical challenges in aircraft blade grinding?

(d) Weak rigidity of blade . However, achieving control over the surface quality of aircraft blade grinding poses numerous technical challenges in developing an intelligent and high-precision robotic belt grinding system.

How long do wind turbine blades last?

Wind turbine blades are predicted to have a lifecycle of 20–25 years (Larsen, 2009). It was estimated that about 4.3 × 10 7 tons of wind turbine blade composite waste will be generated by 2050 (Liu and Barlow, 2017).

What are wind turbine blades made of?

Unlike other parts of wind turbines (e.g., nacelle, tower, and foundation), wind turbine blades are typically made of fiber (carbon fiber or glass fiber)-reinforced lightweight polymer composites. Because of the inhomogeneity and complicated nature of these blades, their recycling is economically challenging.
