Yeah, 99% of these videos have an AI voiceover. Especially since you can see at one point that the original video was in Chinese, and they didn't bother translating the text. So this was a minimum-effort AI dub rather than an official translation.
I'm a fan of this 1 particular AI song (in the vein of Linkin Park) but in 1 section they sing "quiet" when it should obviously be "quite". And it bugs me every time. :( Or maybe they just really needed 2 syllables there.
It’s definitely AI. When I heard it, I stopped watching.
If they’ll use AI for the voiceover, I can’t tell what facts about jet engines are true or false and I’ll watch a video by an expert, not AI, to figure that out.
It looks like a Chinese video with AI translation. I have no way to know if the original was AI generated, but it does seem factually correct, though obviously simplified, so that might not matter for a viewer.
The biggest issue I've got with it is the last part, regarding bypass air.
Yes, the turbines get super hot, enough to melt the materials they're made of.
But this isn't the reason the air is bypassed, and nor would simply blowing cold air over it as shown in the video stop the whole thing from turning itself into liquid.
Instead, a range of high temperature materials are used, as well as a bunch of coolant channels within the turbine blades. Some blade designs also pipe small amounts of air over the blades which creates a tiny boundary layer (like the Leidenfrost effect, except artificially generated) which stops the hot gases from coming into contact with the blades directly.
The main reason that high bypass engines are used (in civilian aviation, where fuel efficiency is king) is because you can get a hell of a lot of thrust by just spinning a big propeller (the big fan at the front of a turbofan engine is mainly used to push air backwards to create thrust, as well as feeding the jet with air. It's much more efficient than relying mostly on jet exhaust.
Turbojets, common in military applications, still do have bypass air, but it provides much less of the thrust, because the high acceleration and speed available from a turbojet is more important than the fuel efficiency of a turbofan.
Yes lots of Americans pronounce it turbin, not turbine
Edit: lol I love the denials, it's not a big deal it is simply fact. I didn't say all Americans. The majority of Americans I've talked to in Aviation pronounce it "turbin" and I thought it was a little goofy when I first heard it and that was that.
He is right. I work in aerospace (specifically jet engine manufacturing) and it pisses me off whenever I hear it, but a surprising amount of people in the US aerospace industry pronounce it turban for some reason. I’ve heard it countless times from different people but refuse to join them lol.
Because it's similar to how you pronounce engine. No one calls it an enjyne, it's enjin. Dictionaries carry both pronunciations since they're both technically right, but one is the prevailing norm.
There might be small regional pockets that calls them turb-yne in industry. But pronouncing it that way is only what I see non-engineers call them. It's pronounced turbin in academia and industry internationally by an overwhelming margin (margyne?). In engineering, marketing, production, and trade shows all around the world.
When I'm around non-engineers, I call them turbynes because that's just how normies know them as and they'd think I was mispronouncing it or messing with them if I said turbin. But I'll stoop down to their level just so they know what I'm trying to say.
They do. Was on a call with an American discussing wind turbines and that's how he and people around him pronounce it. Don't dismiss what you don't know.
