A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    1. NEW RULE as of 5 Nov 2024, trying it out
    2. Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    3. Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct-----

It's crazy that a 60 ton metal airplane can just fly (lemmy.world)

I flew for the first time on a plane last week and I've seen planes take off at the airport. It looks crazy. But being on one is totally different like holy shit. The thing just FLIES. It just.... Soars... Through the sky! Like whoa man. Wtf... It's crazy. With how much these things weigh, it's insane to me the thing can just go up and bam, there we are, we're flying now. Like wow... Dude crazy.

oh, go on.

i haven't heard of the updated dynamics of flight.

This article does a pretty nice job of describing all the different theories

I just want to tell the void that I arrived at a similar conclusion about induced high and low pressure zones based on the wing "slicing" the air in half as if it was a continuous material causing cavitation above the wing, and was mocked for it.

thanks, that's a good article.

That's a great article, thanks for the read.

I don't know the full story, only that the fact air particles have to speed up over the top so they match up at the end is incorrect - one at the top, one at the bottom don't actually arrive at the end at the same time. There is something missing.

[–] Fleur_@lemm.ee 5 points 1 week ago (1 children)

This is wrong. Lift is generated from pressure difference. This pressure difference is caused by air moving faster over the top of the wing. I have no idea what you're talking about with air particles matching up at the end.

I vaguely remember seeing a video that explained that how it's usually explained is wrong. That's what they're probably referring to. But it wasn't that we don't actually know how it works, just that the common simplification is not technically correct (which happens often with these things).
