Bonus: Blade Pitch Problems and Structural Damage

In this BONUS episode, Joel and Allen discuss blade pitch alignment with Lars Bendsen of AC883 and blade structural damage with Morten Handberg of Wind Power Lab. Pitch errors create power losses AND bearing damage. Lars explains how a simple laser alignment check can save operators big sums. Resident Blade Whisper Morten Handberg gives us the latest on structural blade issues and the most recent technology to help detect and possibly repair blades.

While Joel and I were at the Wind Energy Hamburg exhibition, we had the opportunity to sit down with Lars Benson of AC 8 83. Lars is based up in Canada, and Lars talked to us about blade pitch angle measurements and how to correct them and why pitch angle measurements are so important to extend the lifetime. Of your wind turbine. And then I meet with our resident Blade Whisperer Morton. Hamburg, a wind power lab. And Morton provides an update on blade structural issues, leading edge erosion, always a problem, and how robots can help improve blade damage inspections. So stay tuned for a large and Morton. This is a great episode. We’re here with my cohost Joel for Wind Power Lab, and we have a special. Quasi Canadian guest, but , I don’t  Morten Handberg: know if you’ll claim that. I don’t think you’ll claim  Lars Bendsen: it either. Canadian. Dans. There you go.  Joel Saxum: Canada with a K. Exactly. ,  Lars Bendsen: yeah.  Allen Hall: This is Lar Benson from AC 8 83 and Joel and I have talked about Lars as this company a number of times on the podcast because Lars does pitch alignment and pitch measurements that dramatically reduce damage to wind turbines. And so we thought we saw Lars here in Hamburg. And we thought what was just corner and find out all the details. So lar walk it to  Lars Bendsen: the program. Thank you so much. So  Allen Hall: can you explain a little bit of what Pitch Alignment is and why it is so  Lars Bendsen: important? Yeah, I think it’s thank you for inviting with this podcast. I think it’s critical that you need a role that is in balance. Yeah. So all three blades have to have the same pitch angle to keep the road I balance. So there’s the aerodynamic balance, and then you have a mass imbalance. Right. They’re equally bad. Right. But we can measure it b
