EP59 – Jetoptera, 3-Wing Jumbo Jets, SpaceX WiFi & More
Will Jetoptera's fluidic propulsion system work, and reach new applications of aircraft? SpaceX wants their satellite wifi on planes--can they make the technology work with existing radomes? And, can a 3-winged jumbo jet really deliver on fuel efficiency and lift projections?

I'm your co host, Dan Blewett. On today's show, we've got a lot of prototypes to talk through. So my co host, Allen Hall here is gonna kind of pick apart a bunch of these different designs, talk about some of the good things and the bad things. And but we'll start with some news, Airbus, talking about hydrogen starlink, internet, potentially providing fast Wi Fi to planes or something pretty interesting that I hadn't thought about. And then we'll get into some different concepts of trialing jumbo jet, and electric sea plane. And a really interesting what's called a fluidic propulsion system on a flying car concept, as well as one that has the wings, detach and fly home. So again, this would be kind of fun. But let's start with news. Allen. So Airbus has said that the, you know, hydrogen is probably not going to be widely used in planes before 2050. So 30 years off, Does that sound right to you? Well, they're talking about larger aircraft, like in a 328 350 kind of aircraft not being able to switch over to hydrogen, I think that's right. The shorter kilometer type aircraft, maybe propeller driven aircraft will be an easier conversion. And it makes a lot of sense, because there's a lot of short routes in Europe and also in the United States, that could handle a hydrogen aircraft, but it's gonna have to be specifically designed. And that's why Airbus is pushing the back a little bit. I think, early on, there was an impression like we're going to make an Airbus A 350. with hydrogen. That's not where Airbus it. I don't think that's where their intent was. I think eventually, yes. I mean, that's that they did put up some PR about that, right. I mean, we saw the promotional things. 2:10But that that didn't have a timeline, if they're talking about hydrogen aircraft. Yeah, I think they can totally 2:18like an ATR 72, or the dash eight q 400 turboprop aircraft, aircraft would be relatively modifiable into a hydrogen configuration. But after that, when you talk about changing a turbo fan engine to hydrogen, and all the infrastructure involved in aircraft to for the fuel system, that's just going to take a long time, because there's so many, so many pieces to it. Hydrogen is a very small molecule, it leaks everywhere. 2:49Whereas liquid fuel doesn't do the same thing. So all that is all the design elements change, and pressures, and temperatures are all different. Just starting over. It's what's what's what Airbus is saying is like, Look, guys want to start over? 3:05We can't do that overnight. We can't even do it in 10 years. Yeah, so it's definitely they're gonna more all these current planes that use turbo fans to just run their course, essentially. And then, like I said, just start from scratch, like a different designer. I mean, do you see it being like a really wacky, very different looking like futuristic looking? Or is it just gonna be an A 320? That's still pretty normal looking that runs on Hydra? Like, is there a reason that it has to be strange looking to be futuristic and use a different system? Because like, all these renderings You see, like, yeah, so Oh, they always seem very science. fictiony. Right, but right, because it has to be that way, or it might look the same. And 2050, I think the aircraft, essentially, it's gonna look the same,
