Did you know?

WebWhen there is no friction between flow lines, the only way flow velocity can change is via this pressure driven acceleration and deceleration. The air entering low pressure area on top of the wing speeds up. The air entering high pressure area on bottom slows down. That is why air on top moves faster. Webforce the wing exerts on the air parcel, which is opposite the upward force the air exerts on the wing. We have Δpy/Δt = (Δm/Δt) vy where Δm = ρwhΔx for a parcel having height h, …

It is useful in understanding relative motion above and below the wing. A similar … WebDec 8, 2014 · The obvious answer is that the air around the wing isn't irrotational. But that seems a bit too simple: they're implying that there's a possible contradiction here. I suspect that the answer is in Bernoulli's or Euler's equations, which I've heard are linked to why planes fly. But that's well ahead in my notes and I don't understand any of that ...
