Understanding Lift & Wings: Upscaling Data for Real Planes

[Dennis U]

Hi guys,

I'm working on a project for school and I have measured the influence of the angle of attack, the wingspan and the speed of the air on the lift force the wing is producing. Now I have the question what these data say about real wings from planes. I've already red it has something to do with the Reynolds number, but I can't link the Reynolds number on the lift the wing produces.

Welcome to the PF.

What reading have you been doing about wings so far?

I've red about Bernoulli's law and I understand why wings don't fall out of the sky. I know the Reynold's number is defined as the ratio of inertial forces to viscous forces.
