This week on Power-Up, we discuss Siemens Gamesa's method for stabilizing wind turbine blades by installing closeout plates. Then Vestas and ZF's idea to replace the metal torque tube in the gearbox with a plastic piece, protecting from current. And finally, an Enercon patent for painting blades in an ombre pattern to lessen visual disturbances. Sign up now for Uptime Tech News, our weekly email update on all things wind technology.

Follow along with me, Allen Hall, and IntelStor's Phil Totaro, as we discuss the weird, the wild, and the game changing ideas that will charge your energy future. All right guys, our first idea is what's turbine blades, and it's an idea from Siemens Gamesa, and it In patent form, as they describe it here, it's what they call a novel approach to stabilizing wind turbine blades without the need for traditional trailing edge beam designs. But what they're really doing is they're installing closeout plates on the, between the aft spar and the trailing edge. So, This idea is pretty much making a wind turbine blade look a lot like an airplane wing, Phil. Philip Totaro: Yeah, especially like an older style airplane wing. So those that aren't familiar with the closeout plate, it's like a rib design that has this, vertical element at different longitudinal locations throughout the Kind of the, the max cord section and in inner portion with the exception of like the, the immediate root section of the blade. But it's, it's interesting to me, besides just the, the general concept here, the timing of this was fascinating to me because they filed for this patent back in April of 2024. And the patent has now published in October and the question Is, is this a potential fix to a problem? Is this what's this really doing? Allen Hall: Well, it's stopping torsion is what it's doing, Phil. It's preventing the blade from twisting too much, which makes me think of a couple of blades that I'm familiar with that have torsion problems. Joel? Joel Saxum: Well, if you look at the image here, so I've crawled around in quite a few blades doing RCA's and failures, and you're always looking for failure modes, so you start getting into a different mindset of when you're crawling around in them. But In multiple blades that I've been in, there's an, what looks like an extra shear web in the, in some of like the max cord region and stuff like that, just to make sure that you keep that part of the shell supported and then that structure rigid there. And in this design, they're removing that extra shear web and putting these closeout plates in there. And it is exactly like you guys say, the design looks like an airplane wing with a bunch of ribs in it. And to me, in my mind I'm, I'm not a, trained structural engineer, but from engineering principles and just kind of physics and forces and a little bit of knowledge there, this to me looks like it could solve some, some pretty big issues. However, in maintenance, that makes things a little bit more difficult because maintenance and construction, because it's harder to place these things in construction, of course, and to get them right. We already sometimes have a hard enough time placing shear webs and getting those right. Now you're adding perpendicular components and multiple ...
