It's crazy that a 60 ton metal airplane can just fly

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. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- Avoid politics (NEW RULE as of 5 Nov 2024, trying it out)
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct

Yeah that's mostly bullshit.
Your arm flies when you stick it out a window, and it isn't shaped like shit, so does a piece of paper.
It's basically like a sail, but horizontally instead of vertically, the onrushing air hits the bottom at an angle, is deflected down, and bumps the wing up.
The rest is just to try to reduce drag on the top (super-critical wings attempting to maximize laminar flow, or at least make the disconnection as far back as possible so turbulence creates the least drag on the wing.
I'm partial to the Newtonian explanation myself, I was explaining my interest the first time I saw an illustration of the Bernoulli principle.
in fact, I just wrote about The Newtonian explanation a few minutes ago:
"the Newtonian makes more practical end complete sense to me sense to me as an explanation for a lift.
maybe the confusion comes from calling the motion of pushing air down "lift"
push-off.
hm. what the heck is an appropriate antonym for lift...
spring-hold.
oh, buoyancy?
maybe we should switch our talk from lift to buoyancy.
rather than generating lift, velocity through the air generates aerodynamic buoyancy due to the increase in downward pressure, or rather the compressed air beneath the airfoil."
Sorry, as an engineer, this whole "shape of a birds wing makes air move faster over it" pisses me off to no end.
Airfoils are shaped the way they are for drag purposes, not whatever crazy things they say, we could make them like massive triangles and they would still work.
sure, i get it.
he did come up with that half explanation 250 what years ago, so I'll give him a pass.
kind of a bummer that a half explanation is his most famous 'discovery" even though he did so much
No, yeah, Bernoulli was a genius who did a lot otherwise, he should be remembered for all his other scientific contributions..
But you fuck one goat...
