Thanks. I’ve tried, but I still don’t see it.
This older quote for example:
To me the two paragraphs seem to say mostly the same thing: both are generating the majority of their thrust in the same direction, (the direction you want the resulting force to pull, and downwind), and both are rotating in the same direction and have their airfoils oriented roughly similar, with a small change in angle of attack.
The only difference I see is that the wind turbine rotor gets its power from the wind so it needs to pivot its blades to take advantage of that, and a propeller doesn’t need to. A wind turbine rotor is like an airplane always in a dive, a propeller is like an airplane always ascending, maybe.
If you wanted the install a wind turbine on an airplane, you’d point it so it generates its lift pointing backward. If you wanted to install a propeller on an airplane, you’d point it so it generates its lift pointing forward. I think. That is I think different.
