While taking King’s Pilot School class I was taught that Bernoulli’s Principal explains how planes generate lift. But a few months later I saw someone post online who said that it is actually debated whether this is true. I thought it was interesting and have been thinking about it lately. A little research found this article in Scientific American which describes the ongoing debate.
It’s quite obvious Bernouilli’s theorem is largely correct, even though it does not cover the entirety of why air behaves like this.
Planes stay in the air because of aerodynamic lift. Planes are designed around this principle and thousands of planes stay in the air because we know this is how it works.
The article is much less about the principle, because even it says it is scientifically true. The focus of the article is “we can’t, like, explain it, man!” It’s a really long “how do magnets work” piece.
Doesn’t really matter how high quality the piece is. The title is too clickbaity. Everyone here on Lemmy is here because we fled shitty internet practices at some point, so we’re fairly sensitive to things like sensational wording. I’m guessing most downvoters did not click the link.
It’s really not. The longer travel of the air over the top of the wing creates an area of lower pressure than the air flowing under the wing, effectively “pushing” the wing upward.
That is true, yes. The shape of the wing creates a pressure gradient, causing the wing to lift up and deflect the air down. Newton’s law requires an equal and opposite force.
This spoon in the sink illustration really shows this:
