In this episode we discuss Boeing 787 tail fin safety issues that appear to be related to shimming. The Boeing 737 Max also went through EASA testing, and a bit of it is beginning to feel politically charged...the Pipistrel Nuuva V300 is a potentially game-changing cargo EVTOL aircraft that could be delivering cargo to remote locations that were previously accessible only by helicopter. Lastly, we dive into the technology behind Chevrons, serrations cut into the trailing edges of jet engine nacelles and nozzles that reduce noise.

Dan: And here on struck, we talk about everything. Aviation, aerospace engineering, and lightening protection.

All right, welcome back. This is the struck podcast episode 26. I am your cohost Dan Blewett and I'm joined here. Remotely with our lighting protection expert. Allen Hall, Allen, how are you?

Allen Hall: Hey, great. Dan, boy--another troubling week for Boeing with the seven 87 on the engineering side of all things, uh, is just the hits.

Keep on coming there. It's gotta stop at some point. Don't you think?

Dan: You think so it's like spreading amongst their fleet now. So in today's show, we're going to start with some of the 737 max testing. So Yas has been testing them and we'll talk about. What they, uh, what they're doing and how it's going.

Um, and our engineering segment where we're talking about Boeing 787 issues. So the Dreamliners got some vertical fin safety issues. Uh, it sounds like shim problems, so yikes and other potential nightmare, I guess, for right now. Um, also we're going to chat a little bit about chevrons and their use in reducing, uh, engine noise.

Cause obviously jet engines are like the. Most intensely loud things on the planet. So every effort to reduce that as important, even a couple of decibels. And then lastly, in our electric tech session, we'll talk about, uh, PIPA stroll. And one of their new cargo planes that they're hoping can really take off.

Uh, no pun intended. The Nuuva V300 is they're hoping can tackle, uh, the helicopter market and replace them where, you know, we've got to ship cargo out to an oil rig, or we got to ship it out. So some other place where helicopters traditionally, the only place that can get there, but these EVTOLs are going to be coming for that market.

So I know you, um, Are a proponent of getting away from helicopters, which are many respects. Do you think more difficult to maintain and have some pretty spectacular failures when they do fail? Which is scary. So, anyway, so let's talk with, uh, let's talk first about the 737 max. So Yas has been testing it.

How has it been going?

Allen Hall: 737 flight testing concluded up in Vancouver, British Columbia, uh,
