WindpowerNL: blade root inserts

WindpowerNL compares blade root inserts to 50 passenger cars pressing onto the blade

Blade root bushings are safety-critical components that connect the rotor blade with the turbine hub, using bolts. The inserts are an important structural load-bearing component and each bushing must have sufficient bonding strength capable of withstanding forces of up to 1000kN, the equivalent force of up to 50 passenger cars pulling the blade at the same time.

Damaged blade root bushings can be repaired on-site in the windpark by using the patented repair method. The blade is dismounted and placed in a repair environment. The faulty bushings are extracted and the patented retrofit "Re-FIT" bushingsis inserted. Epoxy resin is infused using vacuum processing for strong bonding (this part is now show on the image).
