Wait how do we not know how lift works?
I think it's more so that we know HOW it works but we don't know WHY it works
I don't get it, how can you know how it works but not how? Or is it some philosophical why are the laws the way they are?
Trial and error until we got an equation that pretty much tells us exactly what will happen for given variables.
Physics simulations where a computer helps just try out different propeller designs to see how well it works has been helping introduce all kinds of super exotic designs in the last few years cause yeah as someone who did physics; "it's all just agreed upon expected outcome from trying it."
We know Jack shit.
It's like the question "did we invent or discover math"?
Speak for yourself. I'm a student pilot and most of my instructors (who are either retired airline pilots or are trying to build up flight hours to qualify for an airline job) don't understand the science behind it. To be fair, understanding the science doesn't really help you fly a plane...
How do we not know how gravity works??
It's elusive, man. Lack of symmetry really fucks with our shit, yo.
