 * I added WikiProject Energy because varying the blade pitch in horizontal-axis wind turbines is a typical method for controlling rotor speed and power output. --Teratornis (talk) 18:35, 10 October 2009 (UTC)

Confusing
Article defines pitch using Canadian/British coarse/fine terminology and then goes on to talk about pitch using American high/low terminology. The correspondence is not obvious. — Preceding unsigned comment added by 24.207.72.103 (talk) 23:10, 20 February 2015 (UTC)
 * ✅ I agree, not being an expert in the area it is confusing to me also. I have marked the article as confusing for this reason. Joseph2302 (talk) 23:49, 20 February 2015 (UTC)
 * I have explained the terminology and removed the notice. cagliost (talk) 09:04, 22 August 2020 (UTC)

Stall-controlled wind turbines
The article currently says

"Passive (stall-controlled) wind turbines rely on the fact that angle of attack increases with wind speed. Blades can be designed to stop functioning past a certain speed. This is another use for twisted blades: the twist allows for a gradual stall as each portion of the blade has a different angle of attack and will stop at a different time."

This is a correct summary of the reference given, but is it correct? Angle of attack actually decreases with wind speed. The purpose of blade twist is for each part of the blade to have the same angle of attack. Is it possible that different parts of the blade would stall at different times?

Required blade twist is a function of rotational speed of the propeller. Does it have any relationship with forward speed? cagliost (talk) 09:11, 22 August 2020 (UTC)
